Thank you for the praise.
I guess I should have taken some photos while I was building it. I will open it up again and take some. Please hang on. I have to warn you that the inside doesn't look as pretty as the front.
The meters are two of
these. I took them apart and connected the back panels (just a plastic boards). I made one big meter panel (? -- where the numbers are printed) printing on a
plastic label that looks like a hairlined silver panel. I drove them using a control board called TS-VU001. I bought the meters and the driver from Ali Express.
Thanks!
I am afraid the inside is not that professional looking, though. First build audio amplifier but I used to make some ham-radio rigs some forty years ago (then I turned to software and never did much electronics until now).
I used mostly a
handheld power drill. For big, non-round holes I used a
jigsaw I bought a few years ago when I built the wooden amp rack you can see in the picture. With these tools, the precision is not that great. So I bored considerably smaller holes and filed away the rest. I spent a long time filing. It was a curiously satisfying experience, filing metal precisely with patience I didn't have as a teenager when I built the radio rigs. I also started with the back panel so that I would get better by the time I tackled the big hole on the front panel.
