Time for Tessellation #quilt prototype tile layout below. This is an exploded #tessellation, and so far, it's my favorite, because it shows more of the quilt top. #hackerboxes control tile goes in the center.

I am going to do the anchor points for the control tile now. I'm using a historical sail eyelet model and built-in stitches on the #sewing machine to achieve the reinforced holes. Need a good thread to suspend the control tile and provide strain relief for the flexible wire that will route through these holes. Something neutral is what I am looking for.

The control tile will be able to move, therefore utilizing the #accelerometer to change the pattern of the circle of fifths #music #theory theme.

Time for Tessellation quilt top with light emitting diode display printed printed boards laid out like a clock face.
Old sail corner showing the reinforcement stitching techniques I'm going to use to suspend the control tile.

What a cool nerdy explanation video from @breakingtaps of Micro-electro-mechanical devices- #mems devices - in this case #gyroscope and #accelerometer in your phone. So cool.

In a past life, I worked in the commercialization office of a university, selling rights to our patents. A good chunk of them were MEMS devices - and it was always delightful to learn about these microscopic innovations.

NebulaBreaking Taps — The ingenious micro-mechanisms inside your phoneHow does your phone track its position in space? Phones use small micro mechanical chips called MEMS, to monitor accelerations and rotations. Today we're decapping a six axis IMU, printing up some models and talking about how they work.

How _does_ your phone track its relative position/orientation in space? Tiny little accelerometers and gyroscopes!

I dissected an IMU so we could trace it out in detail, play with printed models, analyze high speed footage and look at pretty SEM images

Cheers to all the folks I badgered with questions! ♥ The gyros in particular were a bit of a challenge to figure out, since they don't operate quite like a "textbook" MEMs gyro (or rather, they are more sophisticated in their sensing)

3ax accelerometer/gyro chip. Composite of 3 different chips that I decapped. Didn't get a complete view of top right unfortunately.

I thought the bottom was accel at first, but thinking they are gyros now? Dual mass vibrating kind? Lack of combs on the top devices is throwing me, just a few plates that I can see.

There are "pits" or cutouts under two of the three devices under the bottom, which is contributing to my feeling they are gyros (to help allow coriolis distortion)
