During cleaning up i found this toroidal transformer. As i am always missing some power supply, i decided to build up a power supply out of that.
Yes i know everybody did something like that, and there is a lot of chinese stuff arround where i can get a laboratory supply very cheap.
There are some things which i want to do better:
* real linear output
* easy to use - no complicated UI
* high efficiency
