[edit] Spacebridge Meeting notes from 2010.03.30

Suggestions for improving launch quality and efficiency

- Need a standard process for setting up and testing electronics. This process must be well documented
- Preflight check list.
- Battery check
- Have ?Yay or Nay? call of the Tuesday meeting before the launch. For a ?Yay? call to be made, every critical component must be completed and tested.
- A full check list of what is going up with this launch and their dependencies
- Mark the tank as we open it, to alleviate confusion as to which one was used.
- Always take a second (back up) tank to each launch
- create wiki pages of each payload item, including set up instructions. (list of needed pages are on the bottom of this page.)
- Provide better communication for the drive out of the launch site
- locate stores in the area that can provide forgotten items like batteries and helium


List of tasks that we should do before the next launch

- Test different types of batteries in the freezer (both types of batteries and competing brands)
- acquire a bathroom scale to weigh the helium tanks with.
- Purchase condoms, extra large
- the cannon IS1100 stopped taking pictures shortly after being turned on, probably battery related, but we should test to make sure.


Ideas for next launch

- One battery grid to rule them all!  This would consist of 2 battery systems that connected just prior to the component giving a back up system should one fail.
- add solar cells to the outside to the payload to test energy received as we go up. We can use the datalogger to store the information.
- Use a droid with debian installed (Chris has one) to feed data from a USB hub that had has several web cameras hooked up and save the data out to a USB harddrive. Alternatively we could also use a beagle board (Nils has one).
- Attach LED blinkies or stroke lights (from disposable cameras) to the end of the antenna support arms.
- Add a high pitch buzzer to the payload bus to help locate it
- add brightly colored inflated condoms (balloons will work also) to the payload so that they will float above the final resting place, assisting in locating it.
- Add a video camera, and stream it's feed over a ham radio to a base station.  This would use a NTSC broadcast.  This has the potential to be expensive, so Chris will gather  - a cost estimate for this (both dollar and if possible weight)
- make the video camera steerable.  Even outside of the flight this would be usable as we could then be able to see the area where the payload landed before having to walk there.


Ideas talked about, but decided to be considered independent of the core Spacebridge concept

- Generating Hydrogen quickly and cheaply.  While awesome, it's to dangerous and inconvenient for us to focus on at the moment.
- UAV.  Again awesome, but is a large enough project to be considered independent but closely related and potentially intersecting Spacebridge.


Wiki pages that need to be created and maintained.

- Radio, with set up instructions
- Radio Antena (dipole)
- GPS
- Packet Tracker
- Open Tracker
- G1, including applications used and set up intructions
- Canon A700 Camera, including CHDK, script, battery limitations, SD card limitations and set up instructions
- Canon IS1100 SD Camera, including CHDK, script, SDHC card limitations, instructions
- Payload Bus
- Icrais program
- Android APRS

Next Launch Date!

- Saturday, May 1th

Tasks/Items for next Launch

- payload bus (Christopher)
- mylar bag for the camera (Christopher/Albert)
- active heating element (Brian/Albert)
- A700 vertical (Blake)
- IS1100 SD horizontal (Blake)
- G1 for tracking (Nils)
- G1 expanded accelerometer data (Nils)
- CDMA tracking phone (Christopher)
- package tracker (Christie)
- radio (?)
- Need to order more balloons (?)


Maker Faire

We have decided to attempt to get an adjacent booth to noisebridge for the spacebridge exhibit.

- Christopher is to contact some people there to get this set up.

We also looked into ways to easily and safely move the helium tanks. One way was to get a trailer. They are not expensive, but we lack a place to put it. The other way was a hitch mounted box that would allow us to secure them. This is easier to store, but will have to be custom made.

get regulator from the soda stuff, talk to milo about that or we need to aquire one

HAVE TO GET BALLOONS!!!!! need ask MH for where he got them

WEIGH IN IS NEXT TUESDAY!!!!


need to make a check list of what is going up and their dependencies

looking into this - A700 vertical (Blake) - COMPLETE - package tracker (Christie) ? independently powered and not connected to the opentracker or GPS just started, will look at it on sunday - radio (?) ? currently in the previous state - Need to order more balloons (?)

Be Ready on Sunday - G1 for tracking (Nils) - G1 accelerometer data app (software hardening) (Nils) - CDMA tracking phone (Christopher) - payload bus construction (Christopher) - active heating element (Brian/Albert) - have temp sensor for the open traker (brian/albert) - have extra balloons!! - water proof camera bag (Albert)

Sunday agenda - Install and integrate temp sensor - Payload marking


Standing issues - SD1100 (horizontal cam) Yuri's night failure analysis (Blake)


SUNDAY all hardware must be present for the meeting no new payload items can be added

TUESDAY ALL ITEMS MUST BE WORKING AND TESTED!


Makers faire get a booth regaurdless

wind protection 4 tarps creating an open topped box use PVC pipe for the walls and sand bags on the corners http://www.amazon.com/Dry-Top-12163-16-Foot-5-Millimeter/dp/B0002Z3NP2

regulator to determin the pressure in the balloon

flow meter to tell how much as left the canister

easally changeabel settings for the open tracker

get a club ham radio license

trailar to help get stuff to the space

shelf space for spacebridge
