An Arduino project to log GPS data to a MicroSD using the tiny XIAO ESP32-C3. The components are small and light enough to fit around a cat collar! Now we know where the cat runs around at night :-)

An Arduino project to create a compass that not only points North, but also points to another person. This is very useful for outdoor teams sports like Airsoft.

Transparent HUD for an Airsoft gun that shows how many BBs are left in your magazine and keeps track of your number of kills and deaths during a match. A XIAO ESP32-C3 is used together with a SSD1309 transparent OLED display. An IR Transmitter LED and IR Receiver sensor is used to detect BBs. Video: https://youtu.be/BZJjDX5xyRM

E-Paper based ultra efficient mini personal weather station

A simple Arduino project to show how to setup a BLE Peripheral device and a BLE Central device, and how to send values from the Peripheral to the Central using Notify

A simple Arduino project to show how to continously read analog values directly from the ADC (analog to digital converter) on an ESP32-C3. This is much much much faster than calling analogRead(), so it's useful if you need to read values at a high frequency.

E-Paper Display based efficient NTP Clock

An example of recording audio onto a MicroSD card, using an INMP441 microphone and a XIAO ESP32-C3

The code running on the microcontrollers inside the gesture controlled LED Zeppelin lamp prototype, made as the final project for the 2024 Digital Fabrication Fab Academy overlay course at Aalto Fablab.

My Digital Fabrication Portfolio created for the 2024 Digital Fabrication Fab Academy overlay course at Aalto Fablab, containing extensive documentation for 6 months worth of hands-on learning in designing and manufacturing a wide variety of projects with a variety of different processes.
