     I made a crude CR2032 mod because there's no way I put a Varta back in there…

     I know I should have used @RonsCompVids 's remote battery board but I didn't want to wait for @MuseumJoe to ship it 😛

     For those who can wait, it's there:

     I put all the components back after cleaning them.

     I only replaced the two jumper blocks. I didn't have a fitting DIN plug so I reused the existing one, doesn't look great but still works.

     One of the tantalum caps blew right away… I checked them all for shorts though… 🤔 Anyway, it's on a negative rail so not really a concern.

     Oh, and I cleaned the removed components in vinegar. That poor IC is ready to loose legs.

     Also, I noticed the pad for the negative battery terminal was so gone that the pad left on the other side didn't connect anymore to ground. I had to dig the epoxy to find the ground plane, and solder a wire to it.

     Can you spot the wire on the last photo?

     Today I spent time trying to redraw the silkscreen that went missing… I know it's completely useless 😄

     I had to create my own tools, because it's really hard to get this resin exactly where you want it, either it doesn't stick, or it spreads everywhere… the two-wires paintbrush seems the most effective (done with a 0.1mm wire).
