Temperature Controlled Fan

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.

Keysight E36103A Lab Power Supply Review

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.

Free Inductance Meter PCB - first come, first served

When I made the PCB for the stand-alone inductance meter, I erroneously used a SSOP footprint for the microcontroller (instead of the desired SOIC). The PIC is available in a SSOP package (PIC16F1963-I/SS instead of PIC16F1936-I/SO) but I didn’t have any at hand so I simply made a new board with a SOIC footprint.
