Seeing a heavy load slide around on nearly frictionless air bearings is pretty cool; it’s a little like how the puck levitates on an air hockey table. Commercial air bearings …read more Continue reading DIY Air Bearings, No Machining Required
Fair warning: if you’re going to try to mold uranium glass in a microwave kiln, you might want to not later use the oven for preparing food. Just a thought. …read more Continue reading Nuke Your Own Uranium Glass Castings in the Microwave

[Thomas Sanladerer] wanted to create some molds using 3D printing for concrete and plaster. He used a delta printer with flexible filament and documented his process in the video below.
If you’ve printed with flexible filaments before, you know you need an extruder that has a contained path. [Tom] borrowed a printer, but it didn’t have that kind of set up. The first step was to swap extruders with another printer.

Videos games are a cornucopia of project ideas well-suited to the talents of makers and hackers, and Halloween is as good a time as any to show them off! Reddit user [Tavarin], a huge fan of the Boderlands video games, whipped up a plaster mask — replete with glowing eyes — of one of the game’s signature enemies: the Psycho.
[Tavarin]’s secret to forming comfortable plaster masks is to open his jaw while the wrap is setting — that way he’ll be able to talk without breaking the mask off his face. Hot gluing in and modifying a 60mm PC …read more
