I started the week by getting stuff done! My socket holding project, SocketSetStack, wrapped up after defeating some printer gremlins, and I uploaded code I was proud of, so you can find it on Thingiverse and print your own. If you like, you can change the dimensions to save filament, or fit different sockets. I received some nice comments from coworkers after sporting this on my tool cart.
I never studied music, and I am not a musician. My approach to music was through Wikipedia and math, so when I saw the expression for a semitone, the frequency ratio between two notes in western music, I thought it looked cool, and it reflected my connection to music.
My girlfriend shared a Tweet from an artist who converted a sound wave to a 3D bead. There was not much background on the procedure, printer, or process, but it was clear how they rotated the 2D visualization into a "vase" using a rotate or lathe function. I would wear one.
I started writing about a new project that is wildly different than most of my other ideas. This one came from a simulated combat experience at Grindfest known as the electric knife fights. I assure you, this is far less dangerous than it sounds, and when I finish, it will be safer than ever. The premise is that two people enter a ring with rubber knives outfitted with shocking electronics, and they try to tag each other three times. The cheap tasers sting, but they don't do any damage. The only wounds during last year's fights were from people tumbling dramatically and sharp zip ties on the knives. Now, I am on a team that wants to eliminate all the accidents from faulty equipment.
I had a few ideas for new blade designs, and I wanted to test their usability. From a plastic scrap, I laced bare copper wire through some holes and connected a battery, voltage converter, and a switch. Here, I learned how far a spark could jump since the wires were too far apart. I put a piece of wire across my makeshift blade, and it was obvious everything was running.
Mounting conductors on a rubber blade should be easy, but it could snag on someone or their clothing. One alternative the group talked about was graphite held in some adhesive, like liquid tape. I had the ingredients on hand, so I coated one edge of the blade with black liquid tape and graphite powder. It wasn't conductive, and it didn't stick to the rubber. I'll have to try something else.
The rest of the summary posts have been arranged by date.

One of last year's knives

Proof of concept, not a fighting tool
