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.
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. :)

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

Thanks for your great job, creative with poor budget....
but I want to ask, how much voltage about one LED and totally voltage used?
24V total, typical forward voltage drop is 1.45V per LED, total 12Leds used. Supplied by 24V with 68Ohm in series.
Thanks tom...👍🙏
Thanks tom about yours respect....
On my village... i difficult to get LED 850nm, what I can use LED infrared former CCTV?
So will led strips work or do I need infra red?
Probably IR. You will need to try
Hi. Is this what you are using. 5mm 850nm IR Infrared Launch Emission Tube Diode LED Lamp Emitting
Just add to LED lights from Harbor Freight the end goodbye you're welcome
..and just what small cal can yours read? I tried cheap white leds from Lowes..lol returnable.
Great. Happy for you.
Would have been nice if you showed how to open the case.

you understand $ maybe but not the physics of this. go away

Just go and by one from Amazon then. Bvi
If you think you need to be a science graduate to understand this then... Just wow
