Hi, thank you for the project. Where are the hex files? I don't find it.

Nice work Ron!!!! Thanks for sharing your project.Also nice work with the pcb exposure and the box you drilled...

In your video, you measure 2 twisted wires. Those two twisted wires gave me a headache some time ago when i was experimenting with the capacitance touch buttons. I was using a 2-side PCB for sensor connected on the breadboard with 2 twisted wires... According to my calculations, the capacitance had to be very small, but in fact the PIC had a different opinion and measured almost double the expected capacitance. It was the stray capacitance of the 2 twisted wires :)
