A Laser-cut Plywood Rack for Torx Drivers

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.

Third Update for 2014's Quantifiable Goals

  • Complete one 5k footrace: No progress.
  • Earn Fechter rank in HEMA: No progress.
  • Do 10 pullups in a set: nine
  • Do 100 pushups in a set: 40
  • Do 200 situps in a set (right now I'm at 50–60): achieved on March 11.
  • Add five new videos to Youtube: one
  • Launch three new web projects: one
  • Add five significant projects to my personal site: none as yet.
  • Add eight artworks to my personal site: none as yet.
  • Post 24 new blog entries: this is my tenth blog post this year
  • Launch my crowd-funded project: Still prototyping, nothing to report.

Hard Drive Disc Sander

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!

Second Update for 2014's Quantifiable Goals

  • Complete one 5k footrace: My knees are still not healthy; as soon as I start running again (perhaps I do this too soon?), it's not long before they start giving me pain.
  • Earn Fechter rank in HEMA: No progress as yet.
  • Do 10 pullups in a set: I've reached 9 pull-ups in a set, only one off of my goal, without any particularly dedicated training; it's more a side-effect of all the push-ups and planks and various other strength-training I've been doing.
  • Do 100 pushups in a set (I tested at 21 at the beginning of January): I'm in the high thirties now.
  • Do 200 situps in a set (right now I'm at 50–60): achieved on March 11. I've started doing a lot more planking as it feels like a more concentrated and efficient workout for the core muscles.
  • Add five new videos to Youtube: none as yet.
  • Launch three new web projects: One launched, the administrative interface for our embedded linux terminal server.
  • Add five significant projects to my personal site: none as yet.
  • Add eight artworks to my personal site: none as yet.
  • Post 24 new blog entries: this is my eighth blog post this year; I've fallen off the pace considerably.
  • Launch my crowd-funded project: Still prototyping.

Color Eggs Like an Estonian

Easter came recently, and so I was finally able to dispose of the bag of onion skins I'd been accumulating in my kitchen since the New Year. To understand why, you have to know something about an old, as in pre-PAAS, technique used in Estonia for egg coloring. Other countries in Eastern Europe do something like this too, but I don't know what subtle variations may exist from nation to nation, so I'll just present my own family's method.

The final result
