Pretty excited to put a small damper on all the energy-crisis-fearmongering with only 4 solar panels. There may still be big problems ahead for industry, but at least the Reps Labs are safe from blackouts:
That concludes the ADRmu preparation

New devices that just work are boring, but Arroyo didn't want to send me a broken XXL TECSource

so that the PPM farm can remain in operation independently of electricity costs. Maybe there's even enough power for a little AC unit 😎

I also haven't forgotten about the higher res GbE image sensor I've shown briefly ... but that is somehow stuck in a resolution-limiting 'region of interest' mode and I haven't found out yet how to get to full resolution.

Finally I got the chance to measure my 3 electrical standards with freshly calibrated meters. TWICE 🤯

This is probably not the final version of this vid, because there's some blatant software piracy going on at 8:30 which might get me into trouble 😬

Probably my biggest video project yet ... probably still lots of mistakes to find and correct 😬

The Fluke calibrator saga continues. To import accuracy we need 3 transfer standards with good short term stability: 10V, 10 kOhm and 1 Ohm. In this video we are looking at 2 different 10V approaches.

It looks like I can't give stuff away any more. Nice. Completely reasonable and sane policy there 🙄

Friends, thank you for your patience, sorry that this took so long!
Got enough raw footage for 2 more videos 😵

I made an LT1166-based power output stage. Once finished it can be operated with a few ADCs and DACs to create 4-quadrant devices.

Finally ... uh almost done 🙈
PWM DAC needs some more love and a conclusion at the end is missing.
Anything else you'd wish more details about? Editing the final version now
