This microcontroller module is great as it is cheap, but also incorporates an OLED display. I admit, that the screen is extremely small 0.42″, but it can still display some basic information, and you will not buy a screen and the microcontroller for the price of ($6 or 5.6 EUR). There are at least two… Read More »
RP2040-Zero is a cheap but powerful developer tiny board utilizing a dual core ARM CPU developed by the RaspberryPi team. This particular module was developed by WaveShare.
I was aiming for a smooth transition for one of my Arduino projects, the first tool for that is the ramp library. While the library itself is quite nice, I miss some more comprehensive documentation of it. Working principle Ramp is meant to be used with motors, like servos, to ease up the start and… Read More »
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 »
I always felt the need of a portable monitor. First of all, because I did not had a flip-out screen on my previous camera. But it is also very handy when testing hardware, that requires a screen. But of course it can be used as a secondary monitor as well. The screen I bought for… Read More »
I generally like the idea behind the Wemos D1 Mini system, but I have to admit, that there is a lot of problem with it. This time I was sorting the issue with the Relay shield. Now the Relay shield is a proper one, the only problem is that it occupies pin D1. Pin D1… Read More »
