my first post here, so hope it's on-topic for the forum.
Straight to the point... I have RPi 4-4GB running Astroberry for astro-imaging. The RPi is in the Argon ONE V2 Raspberry Pi 4 Case, and the power supply is the official UK white Raspberry one, all purchased from pihut. I noted originally that there felt like 'buzzing' when touching the case and it's never got any better. When running an imaging session with my telescope, the RPi is controlling DSLR, tripod tracking and a guide camera, all of which when touched feel the same. This can't be good!
I've searched everywhere for other issues and the only one that comes back is suggesting power supply issues. I have this issue with 2 genuine RPi supplies (one belongs to the RPi400, and the other purchased for this), and in 2 very different locations (work and home), so doubtful of a mains issue.
Thinking of debugging further, I took the RPi out of the case and connected to the 'guide-camera' only (USB-C), and the same feeling is apparent on the camera case. So I'm inclined to say it's the RPi itself with the fault, but is there a way I can stop the issue without just deciding that I have to write off the board? It's been in the Argon case purchase, and these devices are regularly used outdoors without issue.
It's most annoying when looking through the camera viewfinder during setup and getting static shocks on nose!
Thanks for your help in advance!
