[Flightcomputer] "Pictura 1" PCB
link). Making this one custom costs like $8. It incorporates a good conenction to hook up your t68i ericsson telephone for serial commands (SMSing), and its used to go with the Radiometrix NTX2 breakout for radioconnections and the Lassen IQ breakout for the GPS connetions, you should make those as well. It is all powered by 3 AAA batteries you paste on top. Then, you have to get a Arduino Pro Mini as well that is the brains of this PCB. I have made these breakouts in a free version of Eagle (which is great, you can download it here). You can make PCB’s for very cheap at www.batchpcb.com or even better at http://www.seeedstudio.com/. Also, i have a few of these boards spare and i don’t use them: if you like, you can have one. Scroll down to download the PCB files in a .zip file.
