AWESOME! I really enjoy someone taking the time to explain this as a Engineer would. You could have considerd a waveguide and shot the LED into the end of the waveguide and used only 4 LED's. This would project the light very evenly down to the photo transistor
Really a great job!! I have an Alpha Chrony (I think it uses the same components, haven´t checked yet though) and as I shoot outdoors it used to work just great, but on cloudy winter days it´s starting to give me some errors. So I find your info really interesting. Thank you man
thanks for sharing! There are some cheap IR illuminators on eBay/amazon for ~$20, I wonder if those would work, they aren't sold in strips though, they are ~20 850nm leds oriented in a circle. Just purchased the $40 kit from competition electronics...
Fuck it. Tried that and gives false inacurate readings. I bought the infared light kit and its spot on accurate. For god sake everyone carrys on lile its expensive. Why have a chrono if you cant afford the proper infa red light kit.
it depends much on the projectile format and reflectivity. I'm using it for research, my gun is fixed, always shoots through the chronograph at about the same position. Works for me.
Am l the only one that found this tutorial hard work. I don't want to know all that technical bull shit, only what parts to use and how to cobble it together. We aren't all science graduates for f***s sake.
