My awesome wife has a laser cutter at work. I dropped by Monday evening with a sheet of dark acrylic and she cut me a #MeArm!

I happened to grab the files for version 3, but I understand there are newer models out there now. In any case, it went together nicely and lined up nicely with my next order of micro servos arriving. UPS had a bit of a snafu with my hardware order, so I had to scrounge around quite a bit at Home Depot (and completely cleared them out of M3 hardware). Other than some longer-than-necessary-and-not-trimmed bolts, everything worked out. Okay, I cracked some of the acrylic around the gripper. Still works.

Instead of installing a microcontroller, I applied a bunch of fuzzy Velcro to the base. I also installed the previously discussed touch sensor board under the pedestal:

I used a roll of sticky copper tape to create touch panels along various MeArm structural elements. Interconnections happened using blue wire wrapping wire (which will probably fail due to metal fatigue at some point) soldered onto various panels. In some cases (namely C and D), two panels are also bridged into one input:

Then I hooked up a few NeuroBytes: three Motor NeuroBytes for three of MeArm's axes (I didn't hook the gripper up as I still need to fabricate a fourth servo adapter) that handle servo control and reflexive motion, and a handful of standard NeuroBytes to add some simple behavior:

As usual it's a jumbled mess, but it does look better in the dark:

Video showing said simple behavior (note the 'frustrated shake' when I touch the back of the arm too many times):

It goes without saying, but if you don't already have a #MeArm you should change that immediately. Made for a thoroughly enjoyable evening of building and wiring, and it's hilarious to watch to boot. Probably would be a lot less jerky with a proper controller, too.
