I was talking about shot timers with a friend, and this project came up. He mentioned, and I agree, that adding a Raspberry Pi to handle all the data storage and user interface would not only make that stuff easier to write, it would also free up the Arduino coding to the sensor stuff (echo detection, etc.) Which led to thinking, why bother with an Arduino? I've not done much GPIO hacking but I can't imagine it would be that hard to get values from a microphone or piezzo sensor, but I don't know if the fidelity would be enough to do echo detection and etc.
Anyway, just a though. I'd still like to see a shot timer that uploaded my sessions to my PC.
The answer, it seems to me, is wrath. The mind cannot foresee its own advance. --FA Hayek Specialization is for insects.
what is the consensus? If you had to by a timer now - which one would it be?
Just letting folks know that the code has been moved to github and updated: https://github.com/hestenet/arduino-shot-timer
