The problem arise when the Ender 3 Pro is connected to a computer via USB.The connection between the two is via USB and the connection bring also the power (+5V).
In my case the computer is a Raspberry Pi 4 running OctoPrint.

Generic RFID 125 kHz reader
Years ago I did buy a small and inexpensive 125 kHz RFID reader.
This article would be a kind of datasheet/notes of this reader and suggestions about how to use it.

3D Printing - Vocabulary
Like all the technologies, 3D print is not an exception and it has some "lingo", its own set of words to describe specifically something or some operations.
This post will be updated often.
Let see some of them to better understand this business.

3D Printing - The beginning
Time to buy, install and use a 3D printer.
What exactly should be done before to buy a 3D printer ? What is necessary to know ?
How to choose a printer ?
My experience.

A developer venting out
Venting out time !
After more than 35 years being a software/firmware developer, one thing that did not improve in this line of work, is the complexity of the developing environments.
It become worse, not better.
If you are not a software developer, stop to read here :) Boring stuff ahead.

Huzzah32 - RFID base module
A basic circuit to play with RFID and the Huzzah32.
It can be used as base for other projects.
The idea is just to have a Huzzah32 connected to a MF RC522 board and a small display, reading an RFID card/tag and showing it on the display.
The RC522 reader uses tags at 13.56 Mhz.

Ancient history - Digicom
Around 1985 I was working in Digicom S.p.A. (still existing).
I worked on many projects, designing some firmware for modem or other TLC products.
