The Story Behind BlockBoy

BlockBoy is a passion project born from a love for engineering and nostalgia. With a decade of experience in automotive electronics, I recently shifted my focus to the world of custom PCB design. When the
LEGO® Game Boy™ set
was released, I didn't see a static display piece, but the perfect challenge to bring my technical skills and nostalgia together.

What began as a personal mission to upgrade my own model evolved into a professionally developed kit for collectors. The goal was to bridge the gap between a static model and a working piece of history. Every detail has been obsessively refined: from a display that perfectly fills the window, to authentic membrane switches that replicate the original feel of the 90s.

BlockBoy is built by a maker, for makers who value technical precision, authenticity, and a clean result.
