will you be selling these?? How much? When?
No plans yet Oddpxl. I guess if there's enough interest I can make the boards open source or maybe offer a complete kit. The parts I'm using are expensive but it might be possible to swap the APD for a pin diode (losing a lot of range in the process) - I'll test it out. Right now I'm just doing this for fun! I gotta get out more...
