Beachmaster Digital

[Qiaozhi]

It will be interesting to see a PI detector designed around the Raspberry Pi Pico.

Started thinking about a digital version of the Beachmaster, here's a little something I've been playing with.

Going to experiment with some direct sampling of the pulse decay slope (16-Bits 1MHz) and I've also taken a leaf out of George's "Voodoo" book and added a channel for VLF sampling to get some idea of phase. Still very early days yet and not yet started on the PCB layout, but this is the overall concept.

Using a rotary encoder for menu selection and a 2" colour LCD display which plugs on the back of the Pico.
