Can you post source code and hardware BOM? Is it using an ATTiny85 or some other 8-bit MCU?

Just curious what you're doing in code.

I can't really tell from the picture but it looks like it could be a 555 timer meaning no code.

Oh, good call, it probably is a 555 timer.

Yup, no code! That's why it's so cheap to make. That also puts me at the mercy of the potentiometer and capacitor tolerances to determine the pulse length, but I accounted for those errors in the design.
