A while back I was looking at service manuals for a few lab power supplies, and I remembered the elegant approach of the HP E361xA series of power supplies. I wanted to see if it is possible to add digital controls, perhaps even making it able to control it via a computer. Ideally, I also wanted to see the current limit when adjusting it, a feature too many power supplies lack.
The good old HP/Agilent model A3611A
So let’s do just that, recreate the lab power supply with some modern goodies added to it.
See how circuits from the past are integrated with modern components to make a power supply controllable via an Arduino compatible microcontroller in the post here.

Thanks for featuring my blog post. As luck has it, I just finished the second part after a few too many months as well.
