Technically possible, but not for the average user and not without modifications, so FX has not released any firmware for it.

It was available for shipment when I posted this thread the first time. Looks like it’s sold out.

Sorry to hear your wait, I read that many others gave up as well on it. I am still on the fence,if I should get this or FX or Garmin.

FX Chrono v2 (want to buy). In Virginia.

Very well done! Thank you for sharing!

I think he is doing it as a hobby first, and as a challenge. Nothing is wrong with that. He can make the electronics for under $10-15 and that's with bluetooth. I can't speak to the moderator part, but if he makes it modular and smaller diameter that can be stuck inside the shroud, etc...

Yes, that's when many people ruined the thin wires coming out of the chrono.

Maybe consider using a paired/matched digital infrared LED-diode ($2-4). This way you do not need any additional circuitry to process the signal. The max speed to sample with a timer a digital input signal on the nRF52840 is 16mhz You can use one digital input pin and run a counter (timer)...

The ESP32-s3 is an energy hog at 23mA. You should use an NRF52 at 2-3mA, if you want bluetooth. For the LED sensors should use infrared (3-5mA) and also protect the lens from lead dust accumulation. Daystate's older barrel mounted chronos had that problem. Running the LEDs at a duty-cycle...

I like the 8.8oz one. Great to carry around on the rifle. Thank you all!

All I know is that I had many nice 5 shot groups at 100 yards, but when I went to 10 shot groups during the same session, the overall groups near doubled in size.
