The S1-AU Mk1 is a beautifully crafted DIY electronics kit designed with classic 7400 series logic chips.

Big clock display with temperatue based on ESP32 and MQTT.

The 6-digit VFD clock is built around 6 Russian IV-22 VFD tubes and looks very familiar to the popular 6-digit Nixie Clock.

All 26 GPIOs are buffered with bi-directional voltage translators to protect the RPi when experimenting with new circuits. Normal and T-board version.

Breakthrough new concept, leading semiconductor technology combined with inherent block chain and new business model for smart sensor applications.

Innovative textile integrated system of sensors, conductors and electronics unit for measuring and transmitting body and position data

Wizama creates an interactive board games console with its ecosystem of connected objects.

3 displays alarm-clock with TFT screen, developped with Arduino

Zener diode noise is processed, captured and recorded on an SD card. Passes all NIST tests for random signals.

        FORMANT is an analog monophonic synthesizer published in the 70’s from Elektor magazine. It has a modular structure that allows it to be constructed step-by-step and expanded at will. It can be built at home and it is an excellent model to fully understand the operation of subtractive-type synthesizers.

Shows time and date and even plays a simple pinball game on your computer or mobile device via WiFi!

There's a breed of cyclists who ride incredible distances. 400km a day, or 4,000km in 10 days. This is a GPS tracker for that kind of lunatic.

Control your WS2812 RGB LED strip via an ESP8266 WiFi access point.

The cold season stresses every car battery. This project helps to prevent deep discharges and record the voltage over a longer timespan.

Using just any PN532 RFID reader/writer board and a USB to TTL cable you can build your own smart card reader and learn about NFC Tags.

Arduino OBD2 diagnostic tester supporting Diamex DXM and Pi-OBD (AGV) modules

Save time if you build a prototype with microcontroller and LCD. Because at least a part of such a circuit is the same you can often use the same PCB.

OBD2 for Raspberry Pi with Pi-OBD add-on board or DXM OBD2 module and OBD2 software taken from my other labs project Firmware Update for OBD2-Analyser NG.

Firmware update for OBD2-Analyser NG. OBD2 software for OBD2-Analyser NG with Bluetooth module running on PC and Raspberry Pi with Bluetooth adapter.

A logical sequel to RNG-5 hardware random number generator- one-time pad crypto system, very secure, virtually unbreakable peer-to-peer communication!

Project with 2x (3x4 Switch) and 16x 7-Segment LED. I use Atmega 1284P with 12MHz / 3.3V on Arduino.Diskussion in German here: https://www.mikrocontroller.net/topic/371684
