Minimalist mesh radio.

I got a 3/4" pvc plug with a mounting ear printed to adapt the solar patio light to fit a standard 3/4" pvc conduit Tee. The battery and on/off switch is in the solar panel housing. That leaves a lot of room in the conduit coupler for that small RAK4631 board.

I swappd out the 18650 battery that came with the solar light for a higher capacity 18650 but that one didn't have a nipple on the positive end. So I did have to put a bubble of solder on the battery holder terminal.

There's a drain hole in the bottom of the PVC Tee and a drain hole in the bottom of the solar panel housing.
