Re: Lightweight word processor (alternative to LibreOffice Writer)?

One solution widely used in this situation is to use pandoc, a converter, which converts plain text documents written in markdown to latex, pdf, html, docx. The syntax is so much easier to remember than latex. While it does make a fairly standard MS word document by default, you can also give it an ...

Re: Pi4 as Desktop computer

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.

I don't know if I would be comfortable using a large desktop with 3D animations and other intensive stuff.

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

You could use MQTT, for example. A very common way to use remote sensors on things like ESP8266 is this. You install an MQTT broker on the RPi which collects data from sensors which send then over the network. The Rpi then collects that data, stores it and allows people to view and plot it in differ...

You can do this in many ways. The simplest is to use a ESP or similar microcontroller and analog temp sensor. It would be around $3 total.
