Multitasking on the Raspberry Pi Pico

Published Nov 23, 2022

Embedded systems always faszinated me. Especially the ways to organize executions on them. Therefore I was happy to find a backup of an article of my hacked website in which I showed different ways of executing tasks on a Rapsberry Pico. One is just running two bare metal implementations on each core of the Pico. In other examples I use different variations of FreeRTOS tasks and bare metal.

Maze Generator

Published Nov 23, 2022

I realy enjoy programming Javascript in the P5 framework. Though Javascript is a weird language, you can have very quick results. This time I tried programming a maze generator algorithm using the iterative version of the randomized depth first search algorithm.

Latching Power Supply

Published Nov 15, 2022

My kids are constantly leaving the garage door open during night. So I am currently developing a project which shall notify me whenever the door is left open. To save power I designed a latching power supply and explained the circuit in an article.

First Step in P5.js

Published Nov 14, 2022

Today I made something very different compared to the projects I usually tinker on. I did a coding challenge in p5.js a Javascript library which allows very easy creation of animated graphics. But as a first project I decided on programing my own version of Minesweeper. Have fun playing it.

Self Etching PCBs

Published Nov 5, 2022

My current project keeps me busy. I had several flaws in my circuit design so that I had to redo the layout and soldering several times. When I finally finished the design I decided to etch a PCB. While doing it I created a page in which I summarized all the steps I do to etch a PCB on my own.

New Start

Published Oct 10, 2022

Due to a brute force attack on my word press blog I needed to start from scratch. I decided to use robust and old technology to reduce the attack surface to a minimum. Hence I create the pages manually without any fluffy editor. I also removed any social media approaches like comments or stuff. I really hope that this time the page will be more robust and endurable so that my work is not in vain and you, my dear guest user, will find lots of helpfull information for your tinkering project.

The first article I like to publish is about requesting data from a DECT device attached to a AVM Fritz Box using Node Red.
