Contest Information

HSIS/Contest Information

Materials

Available Materials

  • GNX-5 (rebranded as Guidepoint) GSM(cellphone)/GPS tracking device
    • Ratmando has the data sheet and pinouts of the current micro controller for this device. He's looking into replacing the micro controller with something like an ATMEGA644
  • Ratmandu may have a camera
    • Brimstone found out that if we take a 1M picture every 10 seconds, that it will fill 7.5GB in 2.5 hours
    • We may be able to get cameras that work with CHDK at Unclaimed Baggage for less than retail cost.
  • Omegix can volunteer his Android G1: HSIS/G1
    • Asking HSIS team to come up with $80 that I'll hold on to until we retrieve my phone (and keep if we don't).
      • The Little Buddy or the Boost Mobile solution would be cheaper, and just as easy Omegix 15:23, 11 March 2010 (CST)
  • Opticron found his Boost Mobile Phone. This combined with a camera taking automated pictures and our electrical needs are met.
  • Cameras
    • Bender
      • 8MP, $85. Confirmed that it works with the special firmware
      • 7.1MP, $55. Confirmed that it works with the special firmware
    • Omegix
      • 4MP, free. Will need CompactFlash memory if we want to find out about the firmware

List of Potential Materials - Source & Pricing

Depending on design, we may not need many of these materials)

  • Weather Balloons
  • Helium
  • Parachute (rocket model type) and streamers
  • String / Fishing Line
  • Styrofoam cooler, small
  • Digital Camera: 5MP, preferably a Sony so we can use CHDK
  • 1 x Memory Card, 8GB
  • 1 x Memory Card, Cheap (size not important)
  • Atmega Processor
  • Free-spinning joints (like found in keychains)
  • Bungee cords
  • GPS
  • Batteries (3 x D Cell)
  • Radar Reflector (Is this something we will make, or purchase?)
  • Shock Cushion for Bottom of payload
  • Radio or Cell Phone
  • Heat Source (like HotHands)

Human Resources

Bill Brown

Bill Brown has expressed interest in helping the project. He can provide balloons, lifting gas, a launch site (on a mountaintop near Hartselle), a ground station and some lightweight tracking payloads. All of it is for his company: High Altitude Research Corp. He invented the Near Space BalloonSat back in 1987. It was the first to take photos and videos in Near Space.

  • Recommendations
    • Use his lightweight tracking payloads instead of the GPS cell phone method.
    • Use the Canon PowerShot series hacked with CHDK (Canon Hacker Development Kit) software.
    • Fly the Flip video cam.
    • Bought balloons for $20.00 each on eBay. Has receipt to prove it for costing.
  • Media

Others

  • Rohan has worked on BalloonSat before
  • Steve Boyer and Sarah Johnstone have worked on BalloonSats before as well

All Interested Peoples

  • Brimstone
  • Spacefelix (HSIS Event Board Liason)
  • Omegix (Acting as local POC/Project Manager)
  • Crashcart (requested no admin duties)
  • bender
  • Ratmandu
