2015-11-13 (F) Weekly Summary

A three-month project came to a close this week! The Wrist Mounted Chording Keyboard had instructions written for the wrist rig portion, which took a whole day, and it was finally published as an Instructable. The text written for these projects is rarely copied from blog posts, much like these Saturday morning updates they are written from scratch to ensure good flow, continuity, and an encompassing knowledge of the procedure. Hopefully this approach doesn't lead to details being omitted. The title, Always Handy, was selected as a shorter, and catchier title for the wrist rig.

Text written for instructions

Despite the effort taken for this project it was not well-received on Instructables.com. The specialty appeal of the project may have been too narrow for the demographic attracted to Instructables. Learning from the Conductive Paint Instructable, which was wildly successful, despite being a quick project, a general appeal seems important to be popular. This should not be a surprise.

Usually my busy weeks meant that a lot of project work happened but this week was busy with work-work. My company sent me to North Dakota for a start-up and I worked longer hours than normal. This meant that I had little time for myself to do project work, projecting (project-eeng). A couple of single-day projects were dredged out of my repository to fill the gaps.

The first single-day project was a Rack Gear I designed for OpenSCAD six month ago. This project was sitting on the shelf for three months before I even started the Chording Keyboard project. Rack gears are useful in linear movement and even LEGO makes them for their Technic line of blocks. Mine aren't natively compatible with LEGO but some plastic glue and careful measurements could force the matter.

The second single-day project was a t-shirt customized with a bleach wash. This technique was hardly created by me but the results looked like they might be fun so I gave it a shot. I was happy with the results and a t-shirt that was sitting at the bottom of my clothes pile has become one of my favorite shirts. Unlike versions which add paint or ink nothing was added to the shirt so the texture and softness were not affected.

The technique was basically
  1. Mask off a section
  2. Spray a mixture of 1/2 bleach and 1/2 water over the intended area
  3. Wait while processing
  4. Rinse off bleach

Custom t-shirt

A new project was started which won't be as lengthy as the keyboard but will be part of my cyberpunk costume. My right wrist will feature the automated keyboard but the left arm will host lock picks held on over-engineered holders meant to act as quick retrieval and quick deployment holsters. This look was important to show the cyberpunk aspect of "High tech and low life."[1][2]

A sketch was made which was the concept of the pick holders. Basically, a set of lock picks were purchased to be costume pieces. Observe all laws regarding owning lock picks and don't even think of using them unless your legally allowed to do so. Measurements were taken from the cosmetic picks and a simple model was made in OpenSCAD.

Concept drawing

First model. Simple

More accurate measurements were taken from the lock picks and style was added in the form of my personal symbol in the end instead of a simple circle. Measurements were taken by referring to a print of the previously modeled version and seeing how much space needed to be added or subtracted. This goes against the measure-twice-cut-once methodology but does make for fast prototyping with less stress. Always a trade-off when prototyping and further unbalanced by 3D printers which allow for inexpensive and almost effortless prototypes to be generated in real-space.

Second revision of lock pick holder

The rest of the weekly summaries have been arranged by date.
