I've upgraded my light tent for macro photography yet again. I reused most of the PVC components from the Mk.1 design but replaced some of the pipes to make the tent wider; I had sometimes been limited that way with the original design. I'm keeping this one at the office instead of at home and wanted to be able to accommodate one of the 23-inch wide patch panels I've designed, which requires a significantly wider light tent.

Upgraded frame on IKEA table

I designed the Mk.2 around some left-over IKEA GALANT parts we had in the office, which yielded a table 47.5 inches wide and 31.5 inches deep. I bought some M10-threaded caster wheels and screwed them into the bottom of the GALANT legs to make the table mobile for ease of re-configuring my office area.

In my product designs at my day job I sometimes specify torx-headed screws. This could be because the heads resist tool damage better. It could be because torx-heads are more available at the time for some particular combination of thread and length and material I need. Or it could just be because they look cool! Whatever the reason I need a number of torx drivers; in the larger sizes 1/4 inch hex-ended bits are just fine but for smaller sizes I prefer to have small screwdrivers for each one. Since I don't like them rolling around loose in a drawer I made a rack out of 1/4 inch birch plywood on the laser cutter.

Here's a quick and dirty demonstration of turning an old hard drive into a very poor disc sander. It took all of twenty minutes, but don't worry: the video's been sped up considerably. Hope you like it!
