Building off of the great work that @DaystateRebel and others brought in the original homebrew fx chrono display thread here:
https://www.airgunnation.com/threads/homebrew-fx-chrony-display.1278760/
I've been working on a new display for the FX Chrono v1 (the one thats on sale now at UA) so I didn't have to use my phone during range days. I wanted something that was larger, visible in sunlight and could export my data after a session. I ended up finding a newer 7.5 epaper (eink) display from Seeed Studio and using that as the base with a built-in esp32c3.
The built-in microcontroller has both BLE and wifi capabilities so its able to connect to the FX Chrono as well as host a basic webserver for setting configuration:
And heres a quick look at the exported csv:
Besides looking for a quick way to reference session data and SD, I wanted the ability to quickly switch between gun and projectile profiles while at the range and see FPE calculations in real time beside the FPS.
Next Steps:
- clean up code and fix a few ble bugs that I've encountered with higher shot counts
- store readings to local disk instead of memory so they are not lost on restart
- reconfigure webserver hosting to utilize its own wifi hot spot
- clean up webui
- clean up code base
- and of course do some more testing at the range!
After I get through the above changes I am happy to post up the code and installation process to get your own v2 display up and running. I am also happy to provide a service to flash the epaper devices with the open source code if it becomes too difficult of a task.
My ask to the community (especially members that have more experience utilizing chrono devices and tuning) is, are there any other features or abilities of your FX chrono that you would like to see implemented or would help in your tuning?
