Re: What is a good replacement for Etcher (ads and ignores privacy)

So, if I want to use windows 10, I cannot write a disk image to a card/stick without special software? Win 10 itself cannot do it some how?

Re: Battery charger IC good for raspberry pi?

It looks good, but I need it to work with li-po or li-ion. Also, it looks very expensive. Right, but the first one was for LiPo. Although it might be considered expensive (not going to judge that) it meet all your criteria, I believe, as it has the auto shut down option, is a HAT, does charging whi...

Or, you might consider using LiFePo batteries which many people use to run 3.3 v microcontrollers without a regulator at all (the voltage is lower than lipo).

Re: Pi Facial Recognition

Traditionally "facial recognition" means a program which can detect a face from a picture. Do you mean this, that you want to count how many faces there are or when a face is in the picture? Because if you mean to detect individual faces particular to one specific person, this is more difficult, alt...

Re: [HELP] Chrome/Chromium Libreelec Rpi4

There at least used to be a simple browser add-on which worked. Forget what it's called. But it was basically capable of rendering text, so it wasn't really suitable for real browsing but worked in an emergency when you needed to check something simple.

Re: Uses for Raspberry Pi Zero/Zero W?

There are many microcontroller Dev boards out there that cost more than what a rpi zero costs. So that is a "spec" that it is hard to compete with. Also, if you want to create a project runn...

Re: Files going 'read only'

Perhaps the device is mounting read only at times and you think that it is the files. You might see an error message in dmesg about this. You can list and change read only flag with hdparm.

It might be a sign that the drive is going bad, they tend to do this when they are showing hardware issues

Correct me if I am wrong, but wouldn't Raspbian have tasksel as it is a Debian derivative? That would make installing KDE a bit easier/complete.

Re: How is 3.5 mm analog audio out on PI4?

If you really are concerned about loosing the USB port (which I suppose most people would not mind), then why not just use a I2S DAC HAT which is what most people interested in high quality audio use anyway? They are not that expensive and are way better than these cheap USB things

It's hard to answer this question because it is so vague and broad. On some level you can use any operating system for midi processing. Of course, as you say, low latency matters in a project like this and there are low latency and real time kernel s for this purpose. https://www.raspberrypi.org/for...

Re: Will Arduino nano and RPI get Damaged on Supplying 5V 3A DC?

Yes, you have to use a lower CPU frequency for lower voltage and when programming plain AVR chips in Arduino IDE, you can select the frequency from a menu. But I'm not sure if these options are exposed for the nano board
