XRC PRO is a powerful, open-source RC transmitter and receiver system using STM32 and NRF24L01. It features real-time control.

A device used to hold wood steady while you cut it or take measurements on it.

A simple but very useful Zener diode tester

The ultimate beginner’s board to learn, build, and master Arduino the easy way.

Aujourd’hui, l’automatisation rend notre quotidien plus sûr et plus simple, en réduisant les risques et en allégeant les tâches répétitives. Je vous présente mon projet : un distributeur de gobelets automatique. Contrairement aux solutions classiques à plusieurs étages d’engrenages, j’ai opté pour un système poulie-courroie : plus simple, plus fiable et facile à maintenir. Cette conception permet de délivrer des gobelets rapidement, en toute sécurité, tout en restant accessible pour une fabrication pratique.

This is a great small portable radio. You probably can't find a cheaper radio on the market than this with similar features.

Expansion board for ESP32 boards.

Minimalistic board that allows you to quickly and easily utilize a silicon photomultiplier (SiPM) within your other projects. Supports a range of input voltages, has a digital (TTL) pulse output for the registered counts and a direct output for the SiPM pulses for easy expansion.

A compact, DIY laboratory power supply platform powered by ESP32, featuring closed-loop motor control for precise voltage and current adjustment, real-time measurement, and an intuitive graphical display. Users can select from predefined voltage and current presets or save custom settings for repeated use. Designed for hobbyists and makers, it enables hands-on exploration of analog and digital circuits with high precision and flexibility, combining practical functionality with an educational and experimental approach.

Learn how to make PCBs at home using just two materials.

Flea-Scope™ is a very low-cost ($18 from Elecrow) and easy-to-use 18 million sample-per-second (Msps) USB oscilloscope and mixed-signal logic analyzer with a built-in waveform generator, and so much more, based on the PIC32MK MCU!

A set of 8 pistons with a timing belt and spark plugs.

Imagine a laboratory where valuable equipment is at risk because traditional locks offer no traceability. Anyone can enter, and if something goes missing, there’s no way to know who was last inside. We designed a smart solution: an IoT-based door security system using NodeMCU ESP8266 and RFID technology that reads electronic ID cards (e-KTP) as access keys. When a user taps their e-KTP & KTM (Student Card) on the RFID reader, the system verifies the unique ID, unlocks the door automatically, and logs the access in real-time to both a local database (XAMPP) and Google Spreadsheet. This system enhances security, enables instant user tracking, and leverages a national ID that everyone already owns—making it cost-effective and easy to implement. It’s not just a smart lock; it’s a secure, traceable, and scalable access control system for laboratories, offices, or dormitories. With this innovation, we move from blind access to intelligent, data-driven security.
