Welcome to our corner of the internet

Two brothers. A lot of projects.

We make things, break things, and share what we learn. Pick a rabbit hole.

On the workbench

be hacked.

Meet Desk Buddy.

03 / THE HUMANS BEHIND THE ROBOTS

Yep, we're actually twins.

We're Mark and Jeff. Our shared interests tend to end up as 3D-printed parts, lines of code, and robots taking over the desk.

This is where we keep it all: the projects, the experiments, and the videos we make along the way. Grab some files, follow a build, or just see what we're up to.
