I’m teaching my last class at West Point Grey Academy this morning, then testing a gearbox I had designed. I’ll have a post some time later today. Watch the twitter feed for an update. Thanks!
If you follow us on instagram you’ll see last night I shot ~15 photos in a row as I assembled an Arm3. Those pictures have now been added to the Arm3 assembly instructions to make things easier.
A more subtle new feature is that the laser cut files have been updated. Every wood part has a unique number in the design, and those numbers were written next to each part on the wood, a bit like the plastic scale models I assembled as a child.
I felt that it would look better if the part numbers weren’t visible on the final assembly. I’ve been taught the error of my ways, in no small part thanks to your awesome feedback. The designs have been reworked and now the part numbers are directly written onto each part. This way they are easy to identify, even after they’re popped out of the frame. It’s as minimal as it can be without sacrificing utility. I like it, it’s good.
My friends Marshall and Gabi over at Protobuilds in Austin, Texas, heard about my experiments with a bed leveling switch and took it to the next logical step: a touchless inductive sensor. No more screws, no more physical limit switches, no more bed levelling problems!
Read a complete write-up on Thingiverse and try it for yourself!
Now if only someone would add linear encoders so we could get closed-loop printing…
We built an Arduino Tetris game with the Arduino Starter Kit and we played music with a piezoelectric speaker from the same kit, so it’s only natural to combine the two and add Tetris music to our game.

In this class at VHS you’ll learn to solder through-hole PCBs, the same skill you would use to put together many DIY kits.
TV-B-Gone is a universal remote that has one job: to turn TVs off.
Class will be $30 for the kit, no attendance fee. Kit includes all the parts and two AA batteries. Class is limited by the number of working irons, not the number of kits.
PS: TV-B-Gones are available in the VHS vending machine, so you can make one any time. Death to TV!
