For years this basic timer has worked very well in our house controlling the central heating. It was a success among all people because it was easy to set up and after the initial configuration we haven’t really touched it for years. It just kept working without getting in our …
I have long been looking for a way to make a word clock (although there is no shortage of clocks in our home…), but until recently I haven’t found a financially reasonable way to make one. What changed is that I recently acquired a desktop 3D printer. This dramatically expanded …
This article is a new iteration on the wall clock I made a while back. (What can I say? I like LEDs, clocks and clock made up of LEDs…) This time I used a new PCB for driving the circuit and I designed a fully 3D printable enclosure for it …
In the following I am going to describe my own version of the light panels that, in my view, eliminate all the disadvantages of the commercial products while keeping all the advantages. I am aware that others have made similar light panels. I am making and publishing my own version, …
(This article is updated regularly as I create new development boards. The new ones are towards the bottom of this page.) Over the years I have created several development boards and breakout boards. Despite their cost (time, effort, money) they are invaluable investments for development. They simplify and speed up …
Some time ago I also completed this project that I never got around to publish. This project is a WiFi-Infrared gateway. I am aware that such commercial products exist, but at the time I needed one for my home the available options all suffered from one or more shortcomings, such …

Introduction Almost a decade ago I made a PIC micro controlled staircase light timer. It has been working really well ever since and now time has come to upgrade it. This time I designed it around the ESP8266 WiFi module as most of my other projects these days. Having WiFi …
Introduction Recently, I have tried a number of cheap WiFi smart bulbs. Usually, they arrive OK from China (although they are in serious need of weeding all the spyware in them), but this particular one failed to do more than a quick flash when I switched it on. No WiFi, …
