Here’s a design I made recently for Dungeons and Dragons scenery using a lasercutter. I created a bunch of tiles based on a standard 25.4mm grid. The walls are made from two layers of 3mm plywood back-to-back, which allows both … Continue reading →

Here’s a quick one day build project, inspired by Kane Pixel’s awesome youtube channel, and this video in particular.  I lasercut the enclosure out of 7mm plywood. And used cheap adhesive acrylic mirrors on all four sides of the inner … Continue reading →

OK, I decided to do a bit more testing, using the CANBUS data of the car, given that a few people have pointed out that “Indirect TPMS” (Tyre Pressure Monitoring Systems) exist, and use the ABS wheel encoders to infer … Continue reading →

This is a question that I’ve seen debated a few times, both in person and on the internet. It’s not quite in the same league as the immortal argument starter “airplane-on-a-treadmill”, but it has many of the same features. To … Continue reading →

I was recently at the Central Coast Amateur Radio Club’s annual get together. And I saw this beautiful glass vacuum tube there. It’s a vintage Russian KP1-4 high voltage capacitor. Basically two metal plates in a vacuum separated from each … Continue reading →

Here’s a project I finished a couple of years ago, but never got around to posting. It’s a way to visualize music differently to the standard notation. The notes are wrapped in a spiral fashion, with one rotation per octave. … Continue reading →

Here’s a quick little project I never got around to writing up. A while ago I was doing a dive into group/category theory and playing around with graphs of various polytopes. I wanted to make a model of the faces … Continue reading →

Examination of the Hypothesis: The hypothesis I put forward in the last post I think has great merit. In particular: This hypothesis explains the consistent presence on the dodecahedra of their two most defining features; the nodules and the varying … Continue reading →

I was pretty happy with my previous hypothesis on the dodecahedron, the string idea fits so well with the observed shape of the nodules, and the device is very satisfying to use and play with. However one thing that it … Continue reading →
