Playing with software, hardware and touching the sky with a paraglider.
Welcome to my website! I’m Michał Słomkowski, if you want to contact me, you will find the details at the bottom of the page. Recent articles published or updated:
Detailed writeup of installation of Webasto Thermo Top Evo auxiliary heater in '94 MB W124. Contains some quirks like using W-BUS emulator and fooling the heater to use already-present circulation pump instead of separate one.
Second module of Octoglow, which contains numerical VFD to display wall time and 433 MHz weather sensor receiver.
Almost all available USB-controlled power strips use 5 V from USB to drive the relay. This is no use with recent PCs, which hold 5 V during sleep mode. I've written alternative firmware for popular DCT Tech USB relay module available from AliExpress, which detects bus inactivity and shuts the relay down when PC is in sleep mode.
I needed to determine the security code of Becker Europa 2000, usually installed in Mercedes-Benz W124. I dumped the contents of an internal EEPROM via I²C and read the code.
I use Digispark module to inject NEC protocol commands to start Microlab 6C speakers and select sound source automatically at startup.
Module which houses the brain of the Octoglow - the Orange Pi Zero single board computer. It also contains I²C DAC to drive analog gauges to show CPU usage in real time.
