The article below is a detailed description of a GPS and GSM based vehicle tracking solution I have created recently. Its major features: Real time location reports using an onboard GSM modem. Has a micro SD card socket for offline storage on a memory card – this way using a …
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 …
I must have thought there were not enough kinds/shapes/etc clocks in the world. Or maybe I thought: “I made one in the eighties, one about 10 years ago, so it is time for another one.” I’m not sure at this stage. What I do know is that I wanted to …
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 …
