Hey, that sounds awesome. Think of a single‑board microcontroller like a small Arduino or ESP32, a few cheap optical sensors, maybe a plastic casing that you 3D‑print. Keep the software open‑source so anyone can tweak it, but store the safety‑critical code in a private branch just in case something breaks. Add a clear QR code for a quick tutorial video and a few color‑coded buttons so people with limited training can use it. We can test it with a simple script that checks sensor readings against a threshold and flashes an LED if something’s off—easy to debug, easy to fix. Let's prototype it in the garage tomorrow, and we’ll tweak the interface after a night of coffee‑driven ideas.

Great call on the calibration step, that’ll cut down on drift issues. I can already picture a tiny screen showing the baseline values and a blinking LED if the watchdog kicks in. The Bluetooth idea is cool, but let’s make the SD card optional—maybe keep a backup log on the board itself first. I’ll sketch a quick board layout tonight, then we can hit the bench tomorrow and test a couple of reference samples. Keep the code in a private repo for now, and once the hardware’s stable we’ll push the whole thing open. Looking forward to the coffee‑driven debugging session!

Awesome, I’ll prep the prototype board and the test jig. I’ll also write a quick script to read the calibration values and log them to a temp buffer so we can dump it later. See you tomorrow with the coffee and a couple of spare parts—let’s make it glitch‑proof.
