Electron CPU usage

Well I ordered a new pi 3 on Amazon and did a fresh install it’s the same thing all over again. Every time the text changes on magic mirror it maxes out my cpu. And it’s starting to overheat as well and I didn’t even change any overclock settings.

Quite infuriating honestly. I don’t know what I’ll try next.

Oh man, that sucks. I’m sorry to hear that. I’m at a lost here. Really, there is no logical reason for that to happen

My last ditch effort is to try a new SD card. The card it came with is a SanDisk 32gb card and it’s just a plain black card and I have this otherone which is a SanDisk ultra 32gb card so maybe that does something.

@wtidwell

I am certainly rooting for you! I think there was/is a walk-through on preparing the SD card, formatting and such, although I don’t remember where. It’s been a long time.

The best of luck to you. Please keep me posted

Just to rule out one more variable: the pi 3 should be fine running at 1080p yes?

Here is my res on an old HP monitor. That’s using the DVI interface. It does not have HDMI.

@wtidwell Yeah I don’t use those plain black sd cards I buy the more expensive ones because of the issues.

I looked to see what SD card is in my Pi but all I could come up with is the wrapper it came in. I bought one of those CanaKit’s with everything included. I don’t want to take my mirror down if I don’t have to, sorry.

I’m beginning to think it’s the SD card. I did a clean install of Raspian on the SanDisk ultra which is the same class (u1) as the other card which was plain black and it seemed like it was a twinge better but not fantastic. Thanks for your input cowboysdude.

I ordered a SanDisk extreme u3 which will get here tomorrow and try that and report back in. Don’t take your mirror down haha

I hope that’s it. Then we can all laugh about it. Keep me posted.

HOW TO FORMAT AN SD CARD AS FAT

Note: If you're formatting an SD (or micro SD) card that has a capacity over 32GB (i.e. 64GB and above), then see the separate SDXC formatting instructions.

WINDOWS

For Windows users we recommend formatting your SD card using the SD Association's Formatting Tool, which can be downloaded from sdcard.org. You will need to set "FORMAT SIZE ADJUSTMENT" option to "ON" in the "Options" menu to ensure that the entire SD card volume is formatted, and not just a single partition. The updated size will be shown after the format is complete.

MAC OS

The SD Association's Formatting Tool is also available for Mac users, although the default OS X Disk Utility is also capable of formatting the entire disk. To do this, select the SD card volume and choose Erase with MS-DOS format.

LINUX

For Linux users we recommend gparted (or the command line version  parted). Norman Dunbar has written up instructions for Linux users.
