"0.1 ppm" open source 8.5 digit voltmeter from CERN
Added 2021-02-19 22:52:08 +0000 UTCFriends, thank you for your patience, sorry that this took so long!
Got enough raw footage for 2 more videos π΅

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

2021-02-20 20:22:39 +0000 UTCGot another, more popular CERN related open source project right here, ready to assemble ... it won't take 3 months this time, I promise :)

2021-02-20 20:11:27 +0000 UTCon it π

2021-02-20 20:08:04 +0000 UTCthank you very much for the hint! Indeed I tried a new method ... replaced it now

2021-02-20 18:59:57 +0000 UTCthis 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!

2021-02-20 12:37:22 +0000 UTCThen 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/
2021-02-20 10:11:01 +0000 UTCThat was 36 minutes?? I didnβt check before watching it, and I thought it was more like 12π
2021-02-20 09:47:36 +0000 UTCGorgeous!

2021-02-20 05:41:00 +0000 UTCWoww.. That's a hell of a build! I'm guessing you're the first non-CERN engineer to build one of these.

2021-02-20 03:42:37 +0000 UTCBeautiful video. My question was why didnβt you use LTC2508 as your ADC? Iβve read that itβs a next-level ADC

2021-02-20 00:40:37 +0000 UTCA precision voltage reference with a few standard voltages for calibration would be a useful tool.

2021-02-19 23:55:01 +0000 UTCDam .. and I just treated myself to a 4.5 digit Fluke 8050A from 1979 .. only a few digits off :-)
