<div>I'm a food hacker and biotechnologist travelling the world learning and teaching food&beverage fermentation and discovering the beauty of life! I'm participating in the hacker movement because of it's openness, versatility and potential to improve the life on this planet. I'm promoting the use of ancient arts combining it with the new ones.<br />
<br />
I'm one of the founding members of [https://www.noisebridge.net/wiki/Tastebridge Tastebridge], currently working for example on [https://foodhackingbase.org/ Food Hacking Base community project] which about similar stuff as Tastebridge in its time but more internationally focused, evolving rather into the "umbrella organization". <br />

<div>===Experimental Incubator (ei) - Project Proposal 20/5/2012=== <br />
<br />
<br />
<br />
'''Abstract'''<br />
<br />
<br />
Experimental incubator is a device designated to control it’s internal conditions. The prototype is going to allow for a temperature regulation both at constant level and more importantly for controlled temperature oscillation. Another factor included is monitoring of it’s electricity consumption. The temperature is a crucial factor in food&beverage fermentations therefore device which is optimized for these purposes is needed. The novelty temperature oscillation function allows to optimize the growing conditions for cultures comprised from multiple microorganisms with wide range of temperature optimas. Next generations will be more sophisticated aiming for measurement and control of CO2, oxygen levels, stirring, humidity etc. The device will be build to comply with principles of low energy consumption, easy to repair and upgradeable structures, sturdiness in accordance with concept of environmentally friendliness. This project is based on an open source aiming to bring this tool to as many brewers and fermenters being as affordable as possible.<br />

<br />
* Things to discuss concerning the design of the control unit and it's heating/cooling system controlled by microcontroller.<br />
<br />
How to “close up” the ventilation duct to the chamber so the insulation is complete???<br />
<br />
How to “switch” the warm or cold air circulation to the incubator and out???<br />
<br />
===== '''The Code''' =====<br />
<br />
This section is about developing the code to allow the arduino microcontroller to control and run the incubator as desired. The basic info for the first steps is here and it will be updated as we progress. The major focus for now will be on measurement of temperature and controlling it by peltier element.<br />
<br />
<br />
'''What needs to be done:'''<br />
<br />
<br />
* 1. temperature measurement by thermistor<br />
<br />
- temperature needs to be measured by thermistor (10 kohm) <br />
<br />
- frequency should be +- every 3-5 minutes (if the heating/cooling phase is not on, than measure every 30-60 seconds)<br />
<br />
- report/print the temperature so it is human readable (serial monitor?)<br />
<br />
<br />
* 2. switching on and off the peltier device based on temperature readings<br />
<br />
- the peltier is 100 W so it will have power source to power it (around 250 W)<br />
<br />
- switch the peltier relay based system on/off by arduino based on temperature reading (more below)<br />
<br />
<br />
<br />
* 3. switching on and off the fans to circulate the air from peltier to the incubator chamber<br />
<br />
- the fans may have to use the power source/relay circuit too or it may be possible to power them through arduino directly not sure about that yet (small 2x 80-40 mm fans)<br />
<br />
- once the peltier is switched on (based on temperature reading) the fan/s has to switch on (does the fan by the heat sink has to be always switched on???)<br />
<br />
- each fan is pointed to the hot respectively cold heat sink with separated air ventilation systems/ducts to the chamber and out <br />
<br />
- the peltier and fans should go a bit "over the desired temperature/overshoot" like a degree or two so they do not switch on/off all the time<br />
<br />
- once the peltier is on the temperature measurement should be performed every 30-60 seconds<br />
<br />
<br />
Well that would be a basic info, if you could have a look on it and please post on Tastebridge discuss or send email to Frantisek Algoldor Apfelbeck and it will be explained in more detail what needs to be, thanks a lot!<br />
<br />
<br />
<br />
'''Here is a very simple example of what we need:'''<br />
<br />
<br />
'''Constant temperature 25°C mode'''<br />
<br />
<br />
Goal - keep the temperature of the incubator constant at 25°C +- 1 one degree<br />
<br />
<br />
Procedure<br />
<br />
- measure the temperature every 3-5 minutes and display it (serial monitor)<br />
<br />
- if temperature differs from desired<br />
<br />
- switch on the peltier <br />
<br />
- switch on the fan by - heat sink (to warm up) or - cold sink (cool down)<br />
<br />
- increase the temperature measurement to frequency once per 30-60 seconds<br />
<br />
- switch off the peltier once desired temperature is reached (with one degree over shoot)<br />
<br />
- switch to the one per 3-5 minutes temperature measurement and display it (serial monitor)<br />
<br />

* Things to discuss concerning the design of the control unit and it's heating/cooling system controlled by microcontroller.<br />
<br />
How to “close up” the ventilation duct to the chamber so the insulation is complete???<br />
<br />
How to “switch” the warm or cold air circulation to the incubator and out???<br />
<br />
===== '''The Code''' =====<br />
<br />
This section is about developing the code to allow the arduino microcontroller to control and run the incubator as desired. The basic info for the first steps is here and it will be updated as we progress. The major focus for now will be on measurement of temperature and controlling it by peltier element.<br />
<br />
<br />
'''What needs to be done:'''<br />
<br />
<br />
* 1. temperature measurement by thermistor<br />
<br />
- temperature needs to be measured by thermistor (10 kohm) <br />
<br />
- frequency should be +- every 3-5 minutes (if the heating/cooling phase is not on, than measure every 30-60 seconds)<br />
<br />
- report/print the temperature so it is human readable (serial monitor?)<br />
<br />
<br />
* 2. switching on and off the peltier device based on temperature readings<br />
<br />
- the peltier is 100 W so it will have power source to power it (around 250 W)<br />
<br />
- switch the peltier relay based system on/off by arduino based on temperature reading (more below)<br />
<br />
<br />
<br />
* 3. switching on and off the fans to circulate the air from peltier to the incubator chamber<br />
<br />
- the fans may have to use the power source/relay circuit too or it may be possible to power them through arduino directly not sure about that yet (small 2x 80-40 mm fans)<br />
<br />
- once the peltier is switched on (based on temperature reading) the fan/s has to switch on (does the fan by the heat sink has to be always switched on???)<br />
<br />
- each fan is pointed to the hot respectively cold heat sink with separated air ventilation systems/ducts to the chamber and out <br />
<br />
- the peltier and fans should go a bit "over the desired temperature/overshoot" like a degree or two so they do not switch on/off all the time<br />
<br />
- once the peltier is on the temperature measurement should be performed every 30-60 seconds<br />
<br />
<br />
Well that would be a basic info, if you could have a look on it and please post on Tastebridge discuss or send email to Frantisek Algoldor Apfelbeck and it will be explained in more detail what needs to be, thanks a lot!<br />
<br />
<br />
<br />
'''Here is a very simple example of what we need:'''<br />
<br />
<br />
'''Constant temperature 25°C mode'''<br />
<br />
<br />
Goal - keep the temperature of the incubator constant at 25°C +- 1 one degree<br />
<br />
<br />
Procedure<br />
<br />
- measure the temperature every 3-5 minutes and display it (serial monitor)<br />
<br />
- if temperature differs from desired<br />
<br />
- switch on the peltier <br />
<br />
- switch on the fan by - heat sink (to warm up) or - cold sink (cool down)<br />
<br />
- increase the temperature measurement to frequency once per 30-60 seconds<br />
<br />
- switch off the peltier once desired temperature is reached (with one degree over shoot)<br />
<br />
- switch to the one per 3-5 minutes temperature measurement and display it (serial monitor)<br />

<div>===Experimental Incubator (ei) - Project Proposal 20/5/2012=== <br />
<br />
<br />
<br />
'''Abstract'''<br />
<br />
<br />
Experimental incubator is a device designated to control it’s internal conditions. The prototype is going to allow for a temperature regulation both at constant level and more importantly for controlled temperature oscillation. Another factor included is monitoring of it’s electricity consumption. The temperature is a crucial factor in food&beverage fermentations therefore device which is optimized for these purposes is needed. The novelty temperature oscillation function allows to optimize the growing conditions for cultures comprised from multiple microorganisms with wide range of temperature optimas. Next generations will be more sophisticated aiming for measurement and control of CO2, oxygen levels, stirring, humidity etc. The device will be build to comply with principles of low energy consumption, easy to repair and upgradeable structures, sturdiness in accordance with concept of environmentally friendliness. This project is based on an open source aiming to bring this tool to as many brewers and fermenters being as affordable as possible.<br />
<br />

<div>This project is about creating an incubator which allows for a creation of a controlled environment which is as friendly to the microbial cultures as possible. The first and most important feature will be the ability to oscillate temperatures in a controlled manner. The idea behind is that the cultures which are composed from many different microorganisms with different temperature optima would proliferate at temperature oscillations rather than at one set temperature which will favor just some of them. The goal is to keep the cultures like [http://en.wikipedia.org/wiki/Kombucha kombucha], [http://en.wikipedia.org/wiki/Kefir kefir] etc. as biodiverse as possible aiming to improve the vitality of the culture, it's probiotic qualities and also it's taste. Here are the details for the current [[Prototype proposal]] which is based on [http://www.arduino.cc/ arduino clone] control element, temperature sensor and [http://en.wikipedia.org/wiki/Thermoelectric_effect peltier heating and cooling] source. The device will be build to comply with principles of low energy consumption, easy to repair and upgradeable structures, sturdiness, all in accordance with the concept of environmental friendliness. This project is based on an open source aiming to bring together interested people from various backgrounds collaborating making this tool available to as many brewers and food hackers as possible.<br />

====Project status 5/10/2011====<br />
<br />
Today (5/10/2011) I've filled up the water bath (polystyrene) container with tab water and added the aquarium heater (200 w). I let it adjust to the temperature of the water to avoid rupture of the glass enclosure and switched it on, set on 30°C. I've moved our [https://www.noisebridge.net/wiki/091_Brew_Masters_workshop_3/10/2011 current experiment] to the water bath and checked within two hours making sure that the temperature of the water bath is appropriate (by my hand, no thermometer available). <br />
<br />
I plan to make the timer work within a day or two but I'll need hand with that because it doesn't have very intuitive interface. <br />
<br />
Below is the short gallery of how did I set it up.<br />

<div>This project is about creating an incubator which allows for a creation of a controlled environment which is as friendly to the microbial cultures as possible. The first and most important feature will be the ability to oscillate temperatures in a controlled manner. The idea behind is that the cultures which are composed from many different microorganisms with different temperature optima would proliferate at temperature oscillations rather than at one set temperature which will favor just some of them. The goal is to keep the cultures like [http://en.wikipedia.org/wiki/Kombucha kombucha], [http://en.wikipedia.org/wiki/Kefir kefir] etc. as biodiverse as possible aiming to improve the vitality of the culture, it's probiotic qualities and also it's taste. Here are the details for the current [[Prototype proposal]] which is based on [http://www.arduino.cc/ arduino clone] control element, temperature sensor and [http://en.wikipedia.org/wiki/Thermoelectric_effect peltier heating and cooling] source. The device will be build to comply with principles of low energy consumption, easy to repair and upgradeable structures, sturdiness, all in accordance with the concept of environmental friendliness. This project is based on an open source aiming to bring together interested people from various backgrounds collaborating making this tool available to as many brewers and food hackers as possible.<br />

====Project status 5/10/2011====<br />
<br />
Today (5/10/2011) I've filled up the water bath (polystyrene) container with tab water and added the aquarium heater (200 w). I let it adjust to the temperature of the water to avoid rupture of the glass enclosure and switched it on, set on 30°C. I've moved our [https://www.noisebridge.net/wiki/091_Brew_Masters_workshop_3/10/2011 current experiment] to the water bath and checked within two hours making sure that the temperature of the water bath is appropriate (by my hand, no thermometer available). <br />
<br />
I plan to make the timer work within a day or two but I'll need hand with that because it doesn't have very intuitive interface. <br />
<br />
Below is the short gallery of how did I set it up.<br />

<br />
'''Heating and cooling unit''' 13/6/2012<br />
OK we are going to play with the relay circuit switching on and off one or two peltier modules (100 w) and fans (120 - 80 mm "PSU") by arduino. I wonder if 250 W power source from PC power supply unit would be suitable? We can get it for free ... We want to use at least one 120 mm axial-flow fan type for taking out the heat/cold from the heat sink connected to the peltier. Where can I find more about the '''static pressure''' values etc.<br />
<br />
* A fan with high static pressure is more effective at forcing air through restricted spaces, such as the gaps between a radiator or heatsink; static pressure is more important than airflow in CFM when choosing a fan for use with a heatsink. The relative importance of static pressure depends on the degree to which the airflow is restricted by geometry; static pressure becomes more important as the spacing between heatsink fins decreases. Static pressure is usually stated in either mm Hg or mm H2O. <br />
<br />
<br />
because in our case we have a heat sink with fins just behind the ventilator. The idea in this moment is to connect two peltiers to one heat sink, one peltier on each side. When we need to cool, one with the "cold side" attached to the heat sink is switch on + the fan in the internal duct and the external fan cooling the external heatsink by the hot side of the peltier are switched on too. When we need to heat up the second peltier with the hot side connected to the heat sink wee switch it on so is the internal fan and if necessary external fan cooling the passive heat sink on the external cold side of the peltier. In this case there would be just one heat sink in the internal circulation connected on one side to the hot side of the peltier module and on the other side to the cold side of peltier module. This would decrease the frictions of air with another heat sink. If the changing of the polarity of the peltier device is easy to do and it doesn't decrease the life span of the module too much, we could do that too.<br />
<br />
So to play with the set up one internal heat sink, two peltiers and arduino we need:<br />
<br />
* bigger hardware<br />
<br />
- 250 W PSU source<br />
<br />
- 2x peltier<br />
<br />
- heat past<br />
<br />
- 2-4x 120-80 mm fans<br />
<br />
- ventilation duct<br />
<br />
<br />
* arduino/circuit<br />
<br />
- arduino<br />
<br />
- 2x relay<br />
<br />
- 2x diodes (IN4001-IN4007)<br />
<br />
- transistor<br />
<br />
- 10 k resistor<br />
<br />
- wires to connect everything<br />
<br />
- and in my case a shit load of luck!</div>Algoldorhttps://www.noisebridge.net/index.php?title=File:Drawing_ei_heating_cooling_circuit_mechanics_fa13062012.jpg&diff=26067File:Drawing ei heating cooling circuit mechanics fa13062012.jpg2012-06-13T03:05:42Z<p>Algoldor: </p>

<br />
<br />
<br />
'''Abstract'''<br />
<br />
<br />
Experimental incubator is a device designated to control it’s internal conditions. The prototype is going to allow for a temperature regulation both at constant level and more importantly for controlled temperature oscillation. Another factor included is monitoring of it’s electricity consumption. The temperature is a crucial factor in food&beverage fermentations therefore device which is optimized for these purposes is needed. The novelty temperature oscillation function allows to optimize the growing conditions for cultures comprised from multiple microorganisms with wide range of temperature optimas. Next generations will be more sophisticated aiming for measurement and control of CO2, oxygen levels, stirring, humidity etc. The device will be build to comply with principles of low energy consumption, easy to repair and upgradeable structures, sturdiness in accordance with concept of environmentally friendliness. This project is based on an open source aiming to bring this tool to as many brewers and fermenters being as affordable as possible.<br />

* Things to discuss concerning the design of the control unit and it's heating/cooling system controlled by microcontroller.<br />
<br />
How to “close up” the ventilation duct to the chamber so the insulation is complete???<br />
<br />
How to “switch” the warm or cold air circulation to the incubator and out???<br />
<br />
<br />
===== '''The Code''' =====<br />
<br />
This section is about developing the code to allow the arduino microcontroller to control and run the incubator as desired. The basic info for the first steps is here and it will be updated as we progress. The major focus for now will be on measurement of temperature and controlling it by peltier element.<br />
<br />
<br />
'''What needs to be done:'''<br />
<br />
<br />
* 1. temperature measurement by thermistor<br />
<br />
- temperature needs to be measured by thermistor (10 kohm) <br />
<br />
- frequency should be +- every 3-5 minutes (if the heating/cooling phase is not on, than measure every 30-60 seconds)<br />
<br />
- report/print the temperature so it is human readable (serial monitor?)<br />
<br />
<br />
* 2. switching on and off the peltier device based on temperature readings<br />
<br />
- the peltier is 100 W so it will have power source to power it (around 250 W)<br />
<br />
- switch the peltier relay based system on/off by arduino based on temperature reading (more below)<br />
<br />
<br />
<br />
* 3. switching on and off the fans to circulate the air from peltier to the incubator chamber<br />
<br />
- the fans may have to use the power source/relay circuit too or it may be possible to power them through arduino directly not sure about that yet (small 2x 80-40 mm fans)<br />
<br />
- once the peltier is switched on (based on temperature reading) the fan/s has to switch on (does the fan by the heat sink has to be always switched on???)<br />
<br />
- each fan is pointed to the hot respectively cold heat sink with separated air ventilation systems/ducts to the chamber and out <br />
<br />
- the peltier and fans should go a bit "over the desired temperature/overshoot" like a degree or two so they do not switch on/off all the time<br />
<br />
- once the peltier is on the temperature measurement should be performed every 30-60 seconds<br />
<br />
<br />
Well that would be a basic info, if you could have a look on it and please post on Tastebridge discuss or send email to Frantisek Algoldor Apfelbeck and it will be explained in more detail what needs to be, thanks a lot!<br />
<br />
<br />
<br />
'''Here is a very simple example of what we need:'''<br />
<br />
<br />
'''Constant temperature 25°C mode'''<br />
<br />
<br />
Goal - keep the temperature of the incubator constant at 25°C +- 1 one degree<br />
<br />
<br />
Procedure<br />
<br />
- measure the temperature every 3-5 minutes and display it (serial monitor)<br />
<br />
- if temperature differs from desired<br />
<br />
- switch on the peltier <br />
<br />
- switch on the fan by - heat sink (to warm up) or - cold sink (cool down)<br />
<br />
- increase the temperature measurement to frequency once per 30-60 seconds<br />
<br />
- switch off the peltier once desired temperature is reached (with one degree over shoot)<br />
<br />
- switch to the one per 3-5 minutes temperature measurement and display it (serial monitor)<br />
<br />

<div>=Introduction to temperature measurements=<br />
<br />
We are all familiar with the classic simple analog thermometer - the one with the resevoir of mercury or alcohol at the bottom. Unfortunately it is not very easy to convert the (optical) readings from this into a digital format so that we can datalog the information from our experiments. But with the Arduino we can take an analog ''electrical'' signal and turn it into a digital one that we can use. We have a number of choices so we need to choose the best ones for the BioBoard, where we'll be doing measurements on biological systems so the temperature range is generally the same as the one for liquid water. We want inexpensive, readily available, sensors that are easy to implement with the Arduino - and have the appropriate range, precision, and accuracy.<br />
<br />
Some of the basic types of electronic temperature sensors include:<br />
*thermocouple - excellent for very wide temperature ranges, up to 2300°C<br />
*resistance temperature detector (RTD) - used up to 600°C, often for industrial applications<br />
*thermistor - generally limited to <150°C, but inexpensive<br />
*digital temperature sensor (DTS) - the output is linearly proportional to the temperature<br />
[[File:Thermometer sizes.jpg|200px|thumb|right|relative sizes of the two sensors]]<br />
<br />
The thermocouple may be seem to be the most versatile - the individual sensors can be quite inexpensive (but to make your own can mean buying enough materials for many probes) and the range large - but the millivolt output requires an amplifier (~$18) to make them compatible with the Arduino, and they have a greater range than we need. RTDs are becoming increasingly common for some applications but require a bridge circuit, and are not as inexpensive or commonly available as we would like. We chose to focus on ''both'' the thermistor and the DTS because they cover the temperature range of choice well, they are inexpensive, and they can be implemented on the Arduino easily - you get two choices, just in case you have a preference, or one is more easily available than the other. The photo shows the 2 sensors that we interfaced (the DTS is the 3 wire one), but note that the digital sensor also comes in a smaller surface mount configuration, and thermistors can be as small as a grain of sand.<br />
<br />
<br />
=Building a thermometer=<br />
<br />
Since your temperature probe will be exposed to moisture or liquid water, it is best to encase it in a waterproof sheath - a good way to do it might be to place it in a plastic tube and seal both the thermistor/DTS end and the wires coming out the far end with silicone aquarium sealant. Leave the tip of the thermistor or DTS exposed, so that you will have a good response time.<br />
<br />
==Digital thermometer==<br />
<br />
The digital temperature sensor is the new kid on the block - it is a chip made by such manufacturers as Maxim/Dallas, Philips, and Texas Instruments, and is made to run off a voltage from 3 to 5.5 VDC, just like the Arduino puts out. We used the [[Media:Maxim-temp-sensor-DS18B20.pdf|Maxim DS18B20]] (Sparkfun and Hacktronics carry them for ~$4 but you can find them for less) and each sensor has unique 64 bit serial code stored in an onboard ROM - this allows you to use more than one sensor at a time. It is rated for the range -55°C to +125°C and has a stated accuracy of +/-.5°C in the range -10°C to +85°C.<br />
<br />

[[File:DTSprobe1.jpg|200px|thumb|right|assembling the DTS probe]]<br />
[[File:One_wire_address.JPG|200px|thumb|right|serial port results for the address finder]]<br />
===What you need===<br />
<br />
*digital temperature sensor such as the Maxim DS18B20<br />
*1" / 25mm piece of acrylic tube<br />
*Wire - you'll need 3 different colours; we suggest red for power, green for ground and white for signal<br />
*Heat shrink tubing<br />
*Aquarium / hot glue <br />
*4.7kΩ resistor<br />
<br />
===Assembling and waterproofing it===<br />
<br />
We've been using this very good, easy-to-follow [http://www.hacktronics.com/Tutorials/arduino-1-wire-tutorial.html DTS tutorial] from Hacktronics - it'll teach you everything you need to know about interfacing with your DTS. We'll give you a quick overview, and tell you how to waterproof your DTS for use in liquids. For the detailed how-to, please see the Hacktronics tutorial.<br />
<br />
First, you have to solder the wires to the chip; remember to pull the heat shrink on ''before'' you solder the joints. Keep careful track of which of your wires goes to which legs on the sensor! Next, string the piece of acrylic tube on the wires, leaving the sensor sticking out about 1" / 25mm. Fill the tube with glue, then pull on the wires to drag the sensor into the tube until the leads are fully covered.<br />
<br />
===Interfacing and measuring===<br />
<br />
Use a solderless breadboard to build your circuit by connecting the ground / #1 leg of the DTS chip to the GND pin on your Arduino board and the VDD / #3 leg to the power strip on the breadboard. Then connect the DQ / #2 leg of the chip to an empty strip on your breadboard, and wire that to the Arduino's digital pin 3. Last, connect the strip to power / 5V using a 4.7kΩ resistor. <br />
<br />
You'll need to download the [http://www.milesburton.com/?title=Dallas_Temperature_Control_Library Dallas Temperature Control] and [http://www.pjrc.com/teensy/td_libs_OneWire.html Maxim/Dallas OneWire] libraries, and run the [http://www.hacktronics.com/code/one_wire_address_finder.zip One-Wire address finder] sketch on your Arduino board to retrieve the unique 64-bit serial code embedded in each device - follow this [http://www.hacktronics.com/Tutorials/arduino-1-wire-address-finder.html tutorial] from the nice people at Hacktronics. <br />
<br />
Once you have the address for the DTS, you can either upload the standard [http://www.hacktronics.com/code/arduino_ds18b20_temperature_sensor.zip One-Wire sketch] to your Arduino board to start measuring temperature, or use the [https://github.com/BioBridge/BioBoardArduinoCode/blob/master/temperature_sensor_NEW.pde modified version] we've made.<br />
<br />
==Thermistor==<br />
<br />
A thermistor is a type of resistor which has a very well known dependence of the resistance on temperature, and the change is quite steep so that we can resolve small differences in temperature. We are using them in place of traditional thermometers, and so they are sometimes referred to a "resistance thermometers" - they are inexpensive, easy to find, and are '''very''' easy to interface to the Arduino. They are specified mainly by their room temperature (25°C) resistance and a common value is 10 kOhms. If many models are available, like from a major electronics supply house, you can also specify the tolerance and you can choose from different shapes and sizes (the size of a match head is good for starters). As well, there are two general types of thermistors - ones that increase in resistance with increasing temperature (PTC) and those that decrease in temperature with increasing temperature (NTC).<br />
<br />
===What you need===<br />
<br />
Besides your thermistor, all you need for the circuit is a "standard" resistor with a value that is the same as the room temperature resistance of your thermistor. You'll be using the standard one to build a "resistive divider" so that you can use the 5 VDC output of the Arduino and have good resolution over the full temperature range of the thermistor (usually something like -40°C to +125°C, perfect for biological experiments). For our examples we'll be using a 10kΩ NTC thermistor (Sparkfun and Hacktronics carry these) with a 10kΩ resistor for the bridge. [[File:Thermistor-schematic.jpg|200px|thumb|right|schematic for the thermistor temperature sensor]]<br />
<br />
===How to build it===<br />
<br />
Solder on wires and waterproof it as described for the DTS above.<br />
<br />
On a breadboard build your simple resistive divider circuit, following the schematic in the image insert.<br />
<br />
===Things to keep in mind===<br />
<br />
R1 is the thermistor in the circuit, so your standard resistor (R2) is the one tied to the Arduino ground. When you buy the thermistor and matching resistor, buy ones with tight tolerances so that you don't have to worry about small errors in the temperature introduced by values which are off the stated values; and you might measure the actual values with a good digital multimeter, just to make sure. Take care when soldering, so that you don't expose the sensor to too high a temperature - you can fry it; before you waterproof, check the resistance one last time, just to make sure everything is still OK.<br />
<br />
===Interfacing and measuring===<br />
<br />
Remember that the Arduino has a digital output with 10 bit (1024) resolution so for the special case where R1 is the same as R2 (that's our situation at room temperature) the voltage will be half of the Arduino's 5 VDC, so we can expect the digital output to be 1024/2 or 512. The code looks like this:<br />
<br />
double Thermistor(int RawADC) {<br />
double Temp;<br />
float resistance = (10240000/RawADC) - 10000; //calculate from voltage divider, for 10k resistor<br />
Temp = log(resistance/10000);<br />
// calculate the temperature, in K, using 4 thermistor model/material specific parameters A, B, C, D<br />
// here we use the values for the Sparkfun/Hacktronics version of the Vishay 10k NTC thermistor (from datasheet)<br />
Temp = 1 / (0.003354016 + 0.0002569850 * Temp + 0.000002620131 * Temp * Temp + 0.00000006383091 * Temp * Temp * Temp);<br />
Temp = Temp - 273.15; // Convert Kelvin to Celsius<br />
// Temp = (Temp * 9.0)/ 5.0 + 32.0; // Convert Celsius to Fahrenheit<br />
return Temp;<br />
}<br />
<br />
and the math part is the Steinhart-Hart equation, which is the relationship between the resistance and the temperature for a thermistor with certain materials properties ([http://en.wikipedia.org/wiki/Steinhart%E2%80%93Hart_equation see here for a description]). On the manufacturer's datasheet for your specific resistor you will find a list of 4 materials constants - usually referred to as A, B, C, and D - that go with it. The most general equation is: <br />
<br />
1/T= A + B*ln(R/Rt) + C*ln(R/Rt)<sup>2</sup> + D*ln(R/Rt)<sup>3</sup><br />
<br />
but check which one is appropriate for the material constants on your datasheet (the ones in this example are for Vishay thermistors which come from Sparkfun).<br />
<br />
=Calibrating a home-built thermometer=<br />
<br />
[[File:Zero_C_noise.JPG|200px|thumb|right|results when the thermistor is immersed in ice water]] [[File:Temperaturebump.JPG|200px|thumb|right|response time of the two sensors]] [[File:Double_probe_baht.jpg|200px|thumb|right|example probes for the two sensors]]<br />
<br />
Everybody needs to be convinced that your homemade instrument is reading what it should - it must be checked for calibration. Most of us only have two easily accessible, well known, temperatures in the biological region of interest that we can produce - the melting point of ice (0°C) and the boiling point of water (100°C, at sea leve)l - and these are good places to start. It can be helpful to use another reference temperature measurement technique which has already been calibrated, such as a commercial digital thermometer, in case or thermocouple (plus a reader for it - I use a Fluke instrument with an adjustable offset in case there is any error at your reference temperatures) is not available. This figure shows the results of a trial where I placed both the thermocouple and the thermistor in an ice+water bath (a double walled coffee mug) and recorded the Arduino output every 10 seconds - both instruments had an efective resolution of .1°C and we are looking at the ''noise'' at a fixed temperature.<br />
<br />
It is not uncommon to see a peak-to-peak noise level of 3 times the resolution, and that is about what the experiment shows for both the thermistor and thermocouple. Note that for this experiment the Arduino output seems to be linear with the calculated temperature, and this what we expect for relatively small changes in temperature - if we are monitoring experiments where the temperature does not change much we can simplify the mathematical relationship between resistance and temperature, avoiding the calculation hassles of the Steinhart-Hart equation. The offset of ~1.3°C between the "Arduino temperature" and the expected value of 0°C -(the reference thermocouple does only a little better than this unless the 0°C offset voltage is very carefully tweaked - and remember that the literature indicates that we can expect up to about 1°C error due to instrument on-board cold junction compensation errors) - is likely because this particular thermistor only has a room temperature resistance tolerance of +/-5%. If measuring and then using the offset is not what you wish to do, you might have to buy one with a better tolerance and generally take extra-ordinary measures. <br />
<br />
The DTS also showed an elevated temperature when in the ice bath - +2°C in this case. This time it is a little harder to understand, and because they are so new there is not much help out there on the web (and I doubt that the vendors have much real experience with them). With the software setting used it had a resolution of .25°C but this is user configurable (between 9 and 12 bits). In order to compare the response time of the two probes we can first immerse them in ice water then remove them and watch the temperature drift upwards towards room temperature - the results are shown in the figure on the right, and because of the construction method the sensor mass is very small compared to that of the probe. The two performed identically, but took ages to reach the new temperature - to get faster response you'll need to decrease the thermal mass of the whole probe ''significantly''.<br />
<br />
If we need to investigate the calibration over a narrower range we can play tricks like add ice to hot water and watch the temperature on both our Arduino output and our reference thermometer slowly drift up/down together - to see how your DIY measurements compare with the calibrated ones.<br />
<br />
<br />
=Making it cooler=<br />
<br />
The acrylic tube we used for waterproofing the sensors is a little on the large size, partly because of the large gauge lead wires used - you can customize your specific raw sensor so that it is encapsulated differently and suits your application more closely. You might want to skip the tube method altogether, just waterproofing the sensor alone with something like epoxy. <br />
<br />
<br />
=Geeking out=<br />
<br />
If you want to hack just a little more then you might choose to use a thermistor that you find out in the world, using ''obtainium'' can be particularly satisfying - such as from a BBQ probe or other similar digital thermometer. These will have a to-be-determined room temperature (25°C) resistance and materials constants, so you will need to measure the resistance at at least 3 different temperatures (some people ignore the "C" constant, so 3 might be enough) and solve the multiple equations to get the constant values. Luckily, websites exist to help you with this process. <br />

<br />
'''Abstract'''<br />
<br />
<br />
Experimental incubator is a device designated to control it’s internal conditions. The prototype is going to allow for a temperature regulation both at constant level and more importantly for controlled temperature oscillation. Another factor included is monitoring of it’s electricity consumption. The temperature is a crucial factor in food&beverage fermentations therefore device which is optimized for these purposes is needed. The novelty temperature oscillation function allows to optimize the growing conditions for cultures comprised from multiple microorganisms with wide range of temperature optimas. Next generations will be more sophisticated aiming for measurement and control of CO2, oxygen levels, stirring, humidity etc. The device will be build to comply with principles of low energy consumption, easy to repair and upgradeable structures, sturdiness in accordance with concept of environmentally friendliness. This project is based on an open source aiming to bring this tool to as many brewers and fermenters being as affordable as possible.<br />

<div>This project is about creating an incubator which allows for a creation of a controlled environment which is as friendly to the microbial cultures as possible. The first and most important feature will be the ability to oscillate temperatures in a controlled manner. The idea behind is that the cultures which are composed from many different microorganisms with different temperature optima would proliferate at temperature oscillations rather than at one set temperature which will favor just some of them. The goal is to keep the cultures like [http://en.wikipedia.org/wiki/Kombucha kombucha], [http://en.wikipedia.org/wiki/Kefir kefir] etc. as biodiverse as possible aiming to improve the vitality of the culture, it's probiotic qualities and also it's taste. Here are the details for the current [[Prototype proposal]] which is based on [http://www.arduino.cc/ arduino clone] control element, temperature sensor and [http://en.wikipedia.org/wiki/Thermoelectric_effect peltier heating and cooling] source. The device will be build to comply with principles of low energy consumption, easy to repair and upgradeable structures, sturdiness, all in accordance with the concept of environmental friendliness. This project is based on an open source aiming to bring together interested people from various backgrounds collaborating making this tool available to as many brewers and food hackers as possible.<br />

<br />
'''Abstract'''<br />
<br />
<br />
Experimental incubator is a device designated to control it’s internal conditions. The prototype is going to allow for a temperature regulation both at constant level and more importantly for controlled temperature oscillation. Another factor included is monitoring of it’s electricity consumption. The temperature is a crucial factor in food&beverage fermentations therefore device which is optimized for these purposes is needed. The novelty temperature oscillation function allows to optimize the growing conditions for cultures comprised from multiple microorganisms with wide range of temperature optimas. Next generations will be more sophisticated aiming for measurement and control of CO2, oxygen levels, stirring, humidity etc. The device will be build to comply with principles of low energy consumption, easy to repair and upgradeable structures, sturdiness in accordance with concept of environmentally friendliness. This project is based on an open source aiming to bring this tool to as many brewers and fermenters being as affordable as possible.<br />

<div>===Experimental Incubator (ei) - Project Proposal 20/5/2012=== <br />
<br />
<br />
<br />
'''Abstract'''<br />
<br />
<br />
Experimental incubator is a device designated to control it’s internal conditions. The prototype is going to allow for a temperature regulation both at constant level and more importantly for controlled temperature oscillation. Another factor included is monitoring of it’s electricity consumption. The temperature is a crucial factor in food&beverage fermentations therefore device which is optimized for these purposes is needed. The novelty temperature oscillation function allows to optimize the growing conditions for cultures comprised from multiple microorganisms with wide range of temperature optimas. Next generations will be more sophisticated aiming for measurement and control of CO2, oxygen levels, stirring, humidity etc. The device will be build to comply with principles of low energy consumption, easy to repair and upgradeable structures, sturdiness in accordance with concept of environmentally friendliness. This project is based on an open source aiming to bring this tool to as many brewers and fermenters being as affordable as possible.<br />

<div>This project is about creating an incubator which will be able to oscillate temperatures in a controlled manner. The idea behind is to create as friendly environment for the microbes as possible with the aim on cultures which are composed from many different microorganisms with different temperature optima. The goal is to keep the cultures like kombucha, kefir etc. as biodiverse as possible aiming to improve the vitality of the culture, it's probiotic qualities and also it's taste. The prototype should be based on [http://www.arduino.cc/ arduino] control element, temperature sensor and simple heat source like air heater or aquarium heater. I believe that because of the climate conditions in Ireland, this piece of equipment is essential for success of larger fermentation movement. <br />

Tastebridge<br />
<br />
<br />
Tastebridge is a food hacking group originating in the http://noisebridge.net Noisebridge hacker community in San Francisco, California, USA. We focus on traditional high quality food preparation combined with today's scientific knowledge and current technology. One of our major goals is to bring the slow food movement to the home and make it more easy and reliable, as the Governator says “sexy”. Our projects encompass artisan food and beverage culturing such as kombucha and soda pop brewing, yogurt making and of course preparation of various dishes from all different parts of the world. One of our major focuses is design and collection of equipment which would help with above mentioned activities. We are interested in building free open source incubators, dehydrators etc. We are looking forward to promote our activities in the communities in different part of the world stimulating their development in the direction of local sustainability.<br />
