I salvaged a transformator from an old broken halogen lamp - anyone remember halogen lights? These were the next big things before LED lights came and ruled the lightning market.
Anyway, the lamp's tranformator has 12V with 1.6A ratings on the secondary (total 20W - those halogens were still juicy ones :). Even better that it also has a switch and mains cable with a plug so it don't need to buy those.
So I decided I can make a variable power supply aka supply lab bench from it with the following parameters:
Variable voltage: 0 - 10V
Variable current: 0-1A ( still not decided that need this function?)
Set common voltages easily: 3.3V and 5V
Display voltage
Measure current (?)
