Slate coasters, laser engraved with the logo of Covalent Spirits, the distillery run by a friend of ours. I made them in December 2025. Their Orange Vodka is excellent.

Here's a set of four on the bed of the laser.

Laser cut "gingerbread" houses

It was laser day in December 2025. My wife wanted a couple of coasters made, and my daughter wanted some cardboard cut into shapes for "gingerbread" houses. Here's one of the houses.

My wife wanted a couple of coasters made. The coasters are slate, engraved with robotics team logos. Here's one with the FIRST logo, in the laser.

And one with the gear-and-lightbulb logo of our team, FRC 8592.

CO2 Laser Setup

In October 2025 I got a new Gweike CO2 laser cutter and needed somewhere to put it.

The table (October 2025)

Fast, cheap… The laser cutter is still shrink-wrapped in the background, and the table is upside down, 2x4 legs sticking up from a plywood top, with a caster waiting to go on.

And good enough. Here's the laser on its finished rolling table, lid open, with the packing foam and exhaust fittings on the floor below.

The exhaust

I needed a 150 mm to 4" vacuum hose adapter. Oh noes, wherever will I get one? I printed it.
