This is the master page for all of my Near Space Ballooning projects

• Bob - My first tracker, Arduinio Pro 328 3.3v, NTX 2 and uBlox MAX 6 on a Veroboard shield
• ProMini - My second tracker, Arduinio Pro Mini V2 328 3.3v, RFM22B and uBlox Max 6, currently dead bug style
• ProMini2 - My third tracker, Arduinio Pro Mini V2 328 3.3v, RFM22B and uBlox Max 6, currently dead bug style

A new series of trackers on my own PCB's, inspired by pAVA and such like.

• HabTrk V006 - B1 - V006 Board 1
• HabTrk V006 - B2 - V006 Board 2

• Launch 1 - Completed 01/12/2012
• Launch 2 - awaiting HabTrk for backup tracker
• Launch 3 - Mini launch using just HabTrk tracker

Frequency range legally available is 434.04MHz - 434.79MHz according to IR2030.
