In a weak/crazy moment of wanting to get my hands dirty with surface mount circuitry and microcontrollers, I went about cloning the Altusmetrum Telemega flight computer over the summer. I currently have a spare that I can't justify hanging on to. The original though was to make sure that I got at least one working board out of the process, but my success rate was 100%.
You can get all of the technical specs from https://www.altusmetrum.com/TeleMega/ if you aren't familiar with them. Some of the construction process specs:
The Telemega pictured below can be yours if you can pique my interest enough. I will consider any offers PM'ed to me during the next couple of days. I will give priority to trades* over cash.*** As with any rocketry electronics, you are responsible for its verification and use. (Check your laws for amateur radio license requirements.) There is no implied warranty from Altusmetrum.
*Trades that might entice me (in no particular order):
***As I mentioned, this was mostly to try my hand at the process and make something I've been drooling over in the process, not to make quick buck or detract from Bdale's and Keith's sales.

- 4-layer PC boards from OSHpark.com
- all components from major US suppliers
- solder paste applied with a mask for correct amount application
- all parts hand-placed under a dissecting microscope (this took HOURS!)
- reflow soldered on a laboratory hot plate
- all components visually inspected
- larger components placed and soldered
- powered up, firmware loaded, RF calibrated
- tested GPS, transmit/receive, and firing circuits

This was a a great way to get my hands dirty with SMD circuitry. My rocket room has temporarily turned into the electronics room. I've made a total of about 12 various devices over the last two months. I started on some easier projects and worked my way up to these.
