Got enough raw footage for 2 more videos π΅

can you make a video on anodising aluminum? that sounds like fun

Not quite sure! I think they are trying to get weed legalized nowadays?

Is Piraten Partei still a thing?

Got another, more popular CERN related open source project right here, ready to assemble ... it won't take 3 months this time, I promise :)
Marco Reps
on it π

thank you very much for the hint! Indeed I tried a new method ... replaced it now

this was a lot of fun to watch. just a question: was your audio properly normalized? it seemed to me that some parts of your commentary were quieter than others, making me reach for the volume control. looking forward to the in-depth videos to come!
Then it would not be a HPM7177 anymore π There are severel reasons CERN decided for a AD7177, one is 1/f noise. If you want to dive deeper into it read the thread @eevblog: https://www.eevblog.com/forum/metrology/hpm7177-adc-from-cern/
That was 36 minutes?? I didnβt check before watching it, and I thought it was more like 12π

Gorgeous!

Woww.. That's a hell of a build! I'm guessing you're the first non-CERN engineer to build one of these.

Beautiful video. My question was why didnβt you use LTC2508 as your ADC? Iβve read that itβs a next-level ADC

A precision voltage reference with a few standard voltages for calibration would be a useful tool.

Dam .. and I just treated myself to a 4.5 digit Fluke 8050A from 1979 .. only a few digits off :-)
