I have a list of my Press STUFF.

I find music from my Electronic Windchimes relaxing, so I wanted a convenient way to play it anytime. The EWC_Box was a battery-powered boombox and the first to integrate pseudo-random melodic instruments with pseudo-random drum beats. I was proud of how it performed and looked.

I have failed at haptic mechanical compasses since 2014, but I made an oversized proof-of-concept, roughly the size of a baseball. When I face north and jostle the device or turn north, I can feel feedback. Now that I have a working design, I can focus on improving and miniaturizing.

I bought an electric screwdriver, but it came with a rubbish case, so I made a custom holder from plywood with the laser cutter.

I decided to have a little fun and build a workaround for Pokemon GO, which required a lot of coordinated movements but rejected mouse and keyboard input. I used a couple of robotic arms to move an auto-tapper around the screen in a pre-programmed pattern.

Facial-recognition cameras are problematic, but you can "jam" them in low light by flooding the area with infrared light, which humans do not perceive. I swapped out the white LEDs in a hat-clip light with IR emitters, and it still ran off the same battery.

If facial-recognition cameras emit visible or infrared light, it is possible to blind them with passive methods, like 3M reflective tape. I cut shapes for the glasses and lined the edges, making them almost indistinguishable from ordinary glasses.

I learned some lessons in Year 9 about building power supplies. This time, I included terminals I could hand tighten over loose wires and barrel connectors. Everything was 12V, except the USB sockets, which included a 65-watt port where I could power a soldering iron.

I desperately want wearable computers to leap forward, but typing while standing is a tricky hurdle. I built a Bluetooth keyboard I could wear and operate like a keytar, but it was QWERTY, so I did not need to relearn any typing skills. The function keys on my left hand opened typing layers for macros and Numpad access.

I had a whimsical idea for a puzzle box inspired by a cryptex, which looked like elaborate bicycle locks. My design was to arrange keyboard keys and mechanical keyswitches in a cylinder. I used twenty-six letters and ten numbers for thirty-six keys, which comes out to six keys on six sides. I installed a battery so people could freely handle it and solve the typing puzzle. When someone gets a letter incorrect, the LED turns green, but when they type the right message, it stays green and flashes when they complete a puzzle.

GrinderCompass MKII was supposed to become a convenient wearable capable of notifying a wearer when walking north. I could not create strong enough feedback from lightweight parts, but I built a wearable-sized unit that I could test with while I worked on other projects.

I was running low on sanding discs for my rotary tool, and replacements seemed exorbitant. I saw some promising variety packs, but I also wanted larger diameter pieces, so I cut ordinary sandpaper sheets into circles with the laser cutter and got my custom size and some new textures. I could also do this with wet/dry abrasive sheets.

I made a two-neck flute that generated telephone tones. I called it a Phlute as an homage to phone phreaking. I painted it red because the electronic device that did this was called a Red Box.
