The seller
I’m Bobricius, an engineer and hardware designer from Slovakia with a deep passion for retro computers, open-source electronics, and creative DIY projects. With decades of hands-on experience, I love bringing vintage computers back to life, often reimagining them in compact and user-friendly forms that are accessible to today’s enthusiasts.
I have designed and built a variety of popular projects, including the Armachat LoRa messenger, PICO-2040 portable computers, the ZX-Spectrum emulators, and several custom cyberdecks and handheld devices. My work often combines classic computing with modern technology, such as HDMI video output, SD card storage, and easy-to-use interfaces.
I regularly share my projects and ideas with the global retro computing community, and my creations have been featured on platforms like Hackaday, Tom’s Hardware, The MagPi, and Tindie. I’m always experimenting, learning new things, and doing my best to inspire others to discover the fascinating world of hardware hacking.
