Hot air stations aren't just great for (de)soldering, but also for making toasted marshmallows.

More images of broken household electronics. This time: The controller of by dishwasher...

It's a one-sided single layer PCB with lots of small bridges, 0 Ohm resistors used as bridges and a few big bridges.

Can anyone who's better at electronics than me tell me how this thing powers it's microcontroller? There doesn't seem to be a transformer.
Can you really get 230V AC to 3.3V DC with just resistors and diodes or am I missing something here?

My clothes dryer broke a few days ago. I decided to open it up to see if I could repair it.

It's now working again.
Public repair instructions/documentation should be standard for all (electronic) devices.

Progress report: Successfully connected the ALU to the data bus and added a data register to the storage.
