Fixing a faulty tachometer

As components get smaller and smaller I'm seeing an increase in a specific failure mode where equipment dies with a very high current draw. And it's all down to one non-semiconductor component.

This is the first task for my new Infiray thermal camera module. It performed flawlessly.

By request, here's a link to the AliExpress listing I bought the thermal imaging camera from. The price should be around £200, so shop about if they increase the price too much.

This also keeps the channel independent of YouTube's algorithm quirks, allowing it to be a bit more dangerous and naughty.
