Ive never had a problem with an SD card before. I use an SD camera and it works perfectly.
Raspberry pi stays in post code if it doesn't detect an OS> I've tried 3 different SD cards and still can't find the issue.
I don't know if temperature sensors get messed up, but the web interface says the processor is at 92F before this happens. I could attach a heatsink to the processor and the walls of the chamber.
Im trying to do some data logging, using a raspberry pi 3 would be super easy as it has a built in WiFi and Bluetooth receiver as well as an SD card. However when the vacuum gets to about -30inHg the Pi shuts off and the red light starts flashing as if there is no OS. Temperatures arent crazy...
Sorry not the best at making graphs as you can see. Speaking of, I actually wanted to go to all the houses next to the power lines and and the residents questions about their health based on how many years they have lived there.
Ill get some pictures when I arrive home. I am not leeching power,just pointed a CFL bulb at the power lines. I could post the magnetic field data I took if you're interested.
