I put together my first Eggtimer kit this week--an Apogee. This is my first rocketry related build though I have successfully built several guitar effects from schematic in the past so I do have a bit of experience with electronics.
This seemed to go together with minimal difficulty. The instructions were very clear and other than the one surface mount part very easy to solder up. When I power up the unit, it appears that nothing is happening--and at first I assumed that was the case and immediately looked for solder bridges or incorrectly installed parts but to my (admittedly old-man) eyes, everything looked ok. Then while I was perusing the instructions I got a 2-second beep. Then nothing further.
After some futzing around (which included breaking the power connector on the board and some sloppy work getting the pins out of the board) I was able to ID that the board is providing a single 2-second beep followed by nothing, almost exactly, and reproducibly, 45 seconds after power up.
Does that ring a bell for anyone in terms of where I should be looking to troubleshoot?
Images are attached. Sorry, they aren't fantastic shots.
