Capsela is Dead, Long Live Capsela

In the magical 80s, there was a building set that stood apart from the rest. Capsela, originally created by Mitzubishi Pencil Company (the Uniball folks) looked like a series of clear plastic spheres with gears and motors inside. The signature Capsela modules served as both enclosure and functional component. The set came with a variety of gear options like planetary gear, worm gear, and clutch capsules. You could use chain drives and propellers. A lot of the parts were water-resistant, and part of the toy’s shtik was that you could make boats out of it with pontoons keeping most of …read more

Building Set Limitations Make for Z-Height Follies

I’m working on a small CNC mill that uses a robotics building set as a starting point. I don’t know what to expect from the process. Maybe the connections will be too wobbly for the machine to be anything but a curiosity. Maybe I’ll be able to do pen plotting and balsa carving but nothing tougher than that. My goal is to have it carve PCBs, but what ultimately is important is that I have a tool whose awesomeness justifies the expense I’ve put into the project.

So far the process has been fun and interesting. But recently the Z-axis …read more
