Contest Information

From contest rules and guidelines online at the contest website.

Caution/Disclaimer

From the 1337arts website: Launching things into the stratosphere can be DANGEROUS! Please contact the FAA (or your respective government body that regulates air traffic) before trying any launches (even if they are under 4 lbs.) to make sure your vehicle won’t be entering restricted airspace and PLEASE check the University of Wyoming’s Balloon Trajectory Predictor (or a similar website) to make sure you balloon won’t be landing in the city/a populated area where it might cause significant damage. Also, be sure to test your balloon’s terminal velocity for descent before launching to make sure it’s within a safe range.

Rules

  • One team per hackerspace. Any size build team, but only 10 people for the launch and retrieval team.
  • Payload must be under 4 pounds (~1.814kg).
  • Parts cost limit of $250.00. Must show receipts or have other proof of purchase.
  • Payload must return with pictures taken from the flight.
  • Only one official launch per team allowed. Notice of official launches must be given by 8 a.m., and a judge must be present for the launch to count.
  • All local laws and ordinances must be followed throughout the entire competition.
  • Balloon camera must take pictures of the curvature of the earth.
  • The Event Board may judge any other conduct considered outside “the spirit” of the event and disqualify a team that does not adhere to it by majority vote.

Scoring

  • Retrieval Time Based on time of balloon launch to recovery. Fastest gets 50 points, next gets 45, and so on.
  • Weight of Payload 5 points added for every 1/2 pound under 4 lb.
  • Cost of Setup Base: 50 points. 0.5 points off for every dollar over $150.
  • Total Points Retrieval Time Score + Weight Score + Cost Score

Event Board & Judges

  • Judges are members of each hackerspace, and will be submitted to the Event Board. They will ensure all rules are

followed.

  • One person from each hackerspace will be on the Event Board. The Event Board will oversee the event, judge each

applicant, and declare winners.

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.

List of Potential Materials

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

  • Weather Balloons
  • 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
