Raspberry Pi Camera Conversion Leads To Philosophical Question
The Raspberry Pi HQ camera module may not quite reach the giddy heights of a DSLR, but it has given experimenters access to a camera system which can equal the output of some surprisingly high-quality manufactured cameras. As an example we have a video from [Malcolm-Jay] showing his Raspberry Pi conversion of a Yashica film camera.

DOOM maps to SVG to laser cutter
I’ve heard a lot about classic Doom’s data format and decided to write some Rust code to extract its maps and convert that to vector graphics I could laser cut.
I’ll go through the process, from the data extraction to the geometry reconstruction to outputting laser-cuttable SVGs, including the geometrical dead end I enthusiastically ran to when I tried to preview the result using bevy.

Furby modified to recite the wisdom of Jorge Luis Borges
While Furby toys are often described as robots, that term would be a stretch. A standard Furby only has a single DC motor to actuate all of the animatronic movement. But a clever gear mechanism controls what moves. If the motor only turns a little bit, it will just move the mouth. It can then turn further to move the ears or eyelids. Bandini discarded the original control board entirely and replaced it with his own to produce sounds, so he just needed to gain control over the DC motor.
Bandini chose to use an Arduino Nano board with an H-bridge for that job. A limit switch tells the Arduino when the motor is in the home position. Then it can rotate the motor the appropriate amount for the desired animatronic movement. Mouth movement syncs with the audio, which comes from a DFRobot DFPlayer Mini MP3 player board. Any time an audio clip is playing, the Arduino will move the Furby’s mouth. To keep it from jabbering on all the time, Bandini added a PIR (passive infrared) sensor. That tells the Arduino when someone moves nearby so it can activate a quote.
