As mentioned in post Water pump controller I was building a system, that controls the water pump and connects to my Home Automation network. The system contains of two units. One is near to the sensors in a humid environment where there are no network coverage, the second unit performs the switching in a safe… Read More »
I have built a water flow controller with two home made panels made around the Arduino infrastructure. One unit is near the sensors measuring flow and pressure, the other one communicating on my home automation network. The two units are connected with RS485.
I have designed a module for controlling window shades as a part of my own home automation project.
For this project I was inspired by Benjamin Heckendorn, where he was building a game for practicing hex numbers. I always wanted to build that, but did not wanted to make my own PCB. Then I came across with the so called LED&KEY board. Actually this is already a 3in1 game, and the binary-game mode… Read More »

It seams, that it is very popular now to build portable bluetooth boomboxes. I already have made an active speaker set, but it does not provide bluetooth connection, and while it was designed to portable, it does not contains battery. So now I wanted to have a more portable one with bluetooth support. The TDA7492P… Read More »
