I’m currently mainly working on my new anemometer design but once in a while I get distracted. For example when my Keysight E3645A lab power supply was making so much noise that I could hardly concentrate. That’s when the idea of this fan controller was born.
I don’t usually do reviews but I just got a Keysight E36103A Lab Power Supply today and since it’s a newly released model there’s not much independent information out there so far. At least when I ordered mine 7 weeks ago I was unable to find a single proper review. So I thought I’ll share my first impressions.
Finished 5V to 12V USB boost converter I frequently need a low-power supply to run a microcontroller system. Typically, one uses a lab power for such purposes. But at least on the desk where I do the programming I don’t have one. Since these systems typically consume little current it would be handy to be able to power them from USB. Most of my devices have on-board regulators so the voltage is rather uncritical. For 3.3 volt devices, the 5V from USB is just right. But others have a 5V regulator so they need a higher supply voltage. And even others might even need 12 volts.
A classic afternoon project. I was in need of a variable voltage and didn’t have a proper lab power supply available. But I did have a solid 12 volts from an old computer PSU. So I built myself this little thing.
