Digitally controlled linear Power Supply

New project is a Digital controlled linear power supply that will be precise down to 1mV and 1 mA in the range of 0-30V. This is my newest project that is in work now.
It will have 2 x 0-30V outputs and a 0-5V in same chassis as my GPSDO reference that is near finished.

10 Mhz GPSDO Reference

Some of my instruments, need a 10 Mhz reference to get accurate measuring. Therefore I build a 10 Mhz GPSDO reference. Comming soon

When using project from this webside, you agree that it is on own risk!
