Isolation Transformer

My isolation transformer can supply 2.5 A. However, without a current meter I never know when I’m about the exceed that maximum current. With this analog current meter I can easily monitor the output of my precious transformer. And it even is a True RMS analog current meter. I doubt there are many of those around!

Power Strip Controller

Sometimes I have an idea in my head to build something. Extend an already existing thing, like a powerstrip for instance. Whether I would need a remote controlled powerstrip or not is irrelevant in this case. And the funny thing is that I can’t stop thinking about such a project until it is finished.
That’s why I’ve built Carl, my powerstrip controller which can be controlled by Telegram and MQTT.

Sonoff And Tasmota

Sonoffs are very affordable, and therefore very popular mains switches from China. The downside is that they use their own proprietary software and servers to control them. This can be changed by installing Tasmota software on them.
This project explains how I’ve done that, so I’ll know what to do when I want to add more of them. Hopefully the information is useful for you too.

IR-Repeater

Infrared control signals don’t travel well through cupboard doors. And yet we tend do like to hide all the equipment clutter away from sight in a cupboard, which usually doubles as a table for the TV to stand on. But how do you control such equipment, when it’s hidden behind a door? Simple with an IR repeater.

Raspberry Pi Eprom Emulator

With this project I’m taking microprocessor programming to the 21st century. No more Eprom swapping during programming. Simply upload the new file the Eprom Emulator and the new program is already running on your vintage 8-bitter.
The project is built around a Raspberry Pi Zero W.

SB-Assembler

The SB-Assembler is a free cross-assembler, which can be used to create programs for a large variety of micro processors and micro controllers. Version 3 of the SB-Assembler runs on any computer which is capable of running at least Python 2.4.

Knowledge base

Here you'll find a collection of information on several topics. At first it was designed for my own reference, but some of the topics in here appear to be very popular, especially the information on IR Remote Control.

My Projects

This is where you'll find the some of my electronics projects. Feel free to browse them for some ideas or use the projects as they are if you think they are useful to you.

Raspberry Pi

I love the Raspberry Pi, I tend to use them for more and more projects. Therefore I think the Raspberry Pi has deserved itself a place on my front page, as well as in the Projects area.

Software section

I have also done many software projects. Some of them can be found here. All software projects are free to download.

Repair and other tips

Here's another little corner on my website. This is where you can find some tips on repairing electronic circuits. It is also home to some general tips and tricks I find useful during my electronics adventures.
And remember, if you can't fix it with a hammer, you'll need a bigger hammer.
