My Lab

In this corner I give you tour around my lab. Eventually it will contain a description of all the instruments I've got, how and why I've got them, and what I had to do to restore them to their original glory. Some of the instruments even will get some useful upgrades, well at least they are useful to me anyway.

CO2 Air Quality Monitor

A friend of mine saved a whole bunch of these CO2 monitors from becoming landfill. We did know they were LoRa enabled CO2 monitors, but with no type number to be found that was about all we knew.
With a lot of detective work I was able to find out more about these devices. Enough to connect them to TheThingsNetwork. And now some of them are monitoring and recording the air quality in my house.

Awning Controller

Our house has a lot of window surface facing the sun, which can cause temperatures to become quite hot inside during the summer months. This can be remedied by automating the awning control. Here's my implementation, which deploys the awning safely, only when necessary, even while nobody's home. And as a bonus, the awning can now be operated from anywhere in the world.

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!

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.

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.

My Lab

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.
