This is exactly the video I needed. No way am I gonna spend that kinda money on a light bar when I can do it myself! Thanks for the help. :)

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

Interesting. Nice research. Thanks. I'm having the same issue with my Pro-Chrono. Particularly at or above 2000FPS.

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...

Thanks for your great job, creative with poor budget.... but I want to ask, how much voltage about one LED and totally voltage used?
@tomtechtod9200

24V total, typical forward voltage drop is 1.45V per LED, total 12Leds used. Supplied by 24V with 68Ohm in series.

So will led strips work or do I need infra red?

Probably IR. You will need to try

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.

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.
