Re: Notepad++

I strongly recommend exploring the text editor options available to the open source community. Notepad++ is a pretty good text editor for Windows, but in comparison to what we have for Linux it's actually kind of crappy. Text editors are such an integral part of working with Linux, they receive a lo...

Re: Poor Man's Pi Safe Backup Supply (UPS)

For LiIon cells, the most important thing is they don't exceed 4.2V per cell, and for the sake of longevity it's best if they don't spend too much time above 4.0V. On the low end, 2.5V is about as low as they should go, and again they are best off not spending too much time at that level. 3.6-3.8V i...

Re: USB Audio out from RPI4 not using a DAC or any other adapter

The Pi has no ability to output analog audio via USB.

I think you're referring to "Audio Accessory Mode" that some phones use to connect headphones because they lack a 3.5mm jack, this isn't implemented on any Pi.

Re: Setting USB current limit on Raspberry Pi 4

The app is just called "Battery Charge Limit" but there's a few others that do the same thing. Without root all they can do is notify you when they hit the set point, actual charge control requires writing to a system location.

Re: Setting USB current limit on Raspberry Pi 4

I don't think there's any way to do that on the Pi, there's no way to limit current at the host level. If the Android device is rooted it's possible to have it stop charging at a preset level, and resume charging at another preset. My HTC 10 stops charging at 85% and resumes at 80, unless I override...

Re: Lakka on RPI Zero - is SD Card transferable to PI3?

It will probably work, it appears there's 3 images available. One for Pi0/1, one for Pi2/3 and another for the Pi4.

The Pi0/1 image probably is optimized to use less RAM, so you might get better performance using the Pi2/3 version, but I see no reason for it not to work.

Re: USB hard drive randomly disconnecting

Lots of modern appliances use BLDC motors for lowered noise, increased efficiency and the ability to run at variable speed.

The controllers for these motors (essentially a variable frequency 3 phase inverter) can make some pretty ugly RF noise if they aren't shielded properly

Re: Drives changed - copy aborted

Is the source drive (the SD card) by chance the active boot device on the Pi? You might need to use rsync if that's the case as it can handle active (changing) filesystems.

Yeah the bad news is that we're pretty much gonna need Nvidia to be involved to make GFN work on the Pi. The hardware is more than capable, but the necessary software stack simply doesn't exist.

Interesting thread for an interesting project. As for choosing a powered USB hub, I'd look for one that has a 5V input instead of a 12V input. The 12V ones will probably be USB-PD capable, hence the need for a higher voltage source. Regular 5V USB devices will be powered through another buck convert...

Last week I was upgrading my ethernet switch and I found a 256MB Pi plugged into it powered on with an 8GB SD card.

As far as I can tell it's only job is to email me if my external IP address changes.

Re: Interesting discovery re Raspberry Pi lightning bolt power warning.

Switching mode power supplies are very not picky about the power they're fed on the input. I've even run them on 50VDC before, with no effect on the output voltage. A 15W power supply for a Pi is going to be drawing around 0.1A at 120V on the input side at full load, the connection would have to be ...
