get the bits in a case
ben biles • 04/05/2023 at 04:13 • 0 comments

starting to get everything in a case.
I think I might need to use 2 x SSR to switch each leg of the 110VAC rather than just one.
It just feels safer and could switch double the power.
I just have to make some buttons with the 3d printer to poke through holes drilled into the case.
I could also do with 3 AC 110V sockets on the side.
The input AC socket is switched and fused.
If I get all this working properly I will change the case for fireproof polycarbonate.
