2021-07-23 (F) Weekly Summary

I made a new recording space. The old one was great, but I don't live there anymore. I may have lost some egg-crate foam in my last move, so I had to supplement with some 12"x12" (30cm x 30cm) squares. Since I didn't want to stick anything directly to the door, I taped the squares to some foam/paper boards and hung them with homemade over-the-door hangers I bent out of music wire.
Sound insulation

I am nearly finished with the B.o.t.H. project. The cover fits well and holds neatly in place. I wrote a script for a video, and I have the recording space where I can capture it. I created a GitHub page for the files and included a compiled Arduino sketch.
Covered wires

I wrapped up the B.o.t.H. keyboard project with a short video. I recorded it in my new sound-insulated space, and it kept the noise out, but it was cramped. I didn't want to spend a lot of time recording and mixing, so I spoke into headphones and read the script, which took four takes.

My newest project is a laser grid like you'd see in a Hollywood heist movie. The project is solely for fun and exercise and not a legitimate security system. All the concessions I made to the design means this would be exceptionally weak at detecting intruders but flashy. Think of a laser harp mixed with a motion sensor.
Concept for 24EngLaserGrid

The first component in my slapdash system will be the camera from a Wii remote. These little devices track up to four infrared points and report them as coordinates. I won't be tracking each blip, just verifying that I can see four dots because anything less than four means someone has broken a beam.
Exploded Wii remote

I got one of the cameras out of a Wii remote, but I scorched the PCB and dislodged the unit from its housing. Getting more cameras shouldn't be an issue, so I ordered enough supporting parts to make a few cameras.
