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.
There have been two previous posts on this project: one on the concept and the hardware and one on hardware testing. You probably want to check them out first if you’re not yet familiar with this project. Or even better: Click here for an overview over this project.
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.
