What this 'Electronics Workbench' is all about

The best way to know everything about microcontrollers, programming, PCB design, protocols and other embedded systems stuff is to start playing around with it. In the course of this travel, I will blog about my experiences and present some hopefully interesting projects and tips along the way.

Please come back from time to time to read about new projects, experiences, reviews and discoveries I make while working on the design, construction and programming of mostly microcontroller-based circuits.

Yet Another Blog about IoT... yawn...?

I realize that for many of the projects I am undertaking right now or will start in the future, there are somewhat similar solutions out on the internet.

Without any intention to downplay all the inventive and creative work being displayed on the internet that give me quite some inspiration too - thanks for that! - in one respect this blog will differ from some (many?): while many sample projects are prototypes created on breadboard with a few shields, wires, Arduino's, wall warts and the likes, the end result of my projects will be a directly applicable product, fully integrated, with the right form-factor PCB (for instance to assemble it in the wall behind a mains power switch).

Building a finalized 'product' requires some extra effort and attention for details (like form factor constraints). Since I have this annoying urge/need to know all the gory details about everything that has some electronics inside, or that I build myself, from time to time I may dive a little deep into he details, or wander off a bit. But all for a good cause: understanding and just knowing how and why it works. Besides, what's the fun in just copying/using something? Having said that, from time to time I may borrow some ideas and partial solutions from others (and will try to acknowledge the original author(s) when I do).

Retro computing

Going back to the 70's and 80's and trying to recreate my very first microcomputer with the SC/MP microprocessor.

8-bit rules

Honoring the days of 8-bits with modern day microcontrollers of the Atmel AVR Tiny and Mega family.


Working on various components that can be applied in a home autmation environment.


Discussing design, fabrication, testing and assembly of PCB's and circuits.

Open source PCB Design

After having worked with the free version of EagleCAD for a few years, which is limited to two layers, I decided to check-out KiCAD once again. Soon you can read all about my close encounter of the third kind with KiCAD in the blog section.
