I got into airsoft recently, and I wanted a way to measure the BB’s velocity. The cheapest chronographs I could find were ~60-70€. I thought making one myself would be much cheaper and a good learning experience. The total cost was about 15€.
I tested it with an Army Armament R504, its specs sheet says it shoots at 300 FPS, I measured 298 FPS which is within the margin of error.
You will find schematics, component list and the code at my blog and at GitHub.
