Oh well, can’t have everything…
Music player on my PC loaded with 30 hours of tracks labeled “Unknown title, Unknown artist” because my media splitter doesn’t label the tracks it outputs.

Got my wav->mp3 track splitter to work! Now I have 412 tracks loaded onto my Shokz OpenSwim Pro 2 headset, and I know a bit about Rust! 🦀

Selfie of me wearing striped sweater and Bluetooth headphones with an integrated mp3 player loaded with music and looking smug because I taught myself a bunch of the Rust language over the weekend.

I haven’t yet had the chance to program Rust professionally, so I am learning it on my own. My first Rust project is processing a large 59 gig wave file using AVX512 SIMD and rayon to calculate a binary heap of RMS levels but ultimately I want to use DSP to split it into tracks.

The speaker transducer is wired to the crossover and ready to be mounted in the housing.
A two-way coaxial speaker (woofer tweeter combo) wired to two crossover networks and connected to a small amplifier.

The face of my speaker enclosure stuck to the printing plate when the time came to remove it 😢
Printing again with more wall loops and more infill.

Revised coaxial speaker enclosure with a little shelf for crossover components and mounting holes for a speaker grille.
3D printed baby blue stubby missile-shaped speaker enclosure showing the opening for the speaker to mount in and a perforated internal shelf and terminals mounted in the back of the enclosure. The print is showing signs roughly spots from the plastic having slightly overheated; The printer settings (extrusion temp or print speed) need tweaking.

3D printed speaker housing with no supports. I’m surprised this worked.
3D printed speaker housing that’s a ring with a half sphere on the back in orange red plastic back of speaker housing showing that it is closed except for two holes in it for wiring terminals close-up of inside of the speaker housing showing that the 3d printer struggled a little bit but got the job done

Simple DMX512 Controller using an Adafruit Feather nRF52840 using mechanical encoder. Future plans are to get the high res magnetic encoder connected and implement Bluetooth LE receive in the C/C++ firmware.

I wanna make a DMX512 controller.
A hand has a small 3D printed frame on it holding two rotary encoders, a DMX connector, and an Adafruit nRF52840 Feather MCU. So far, nothing is wired 😫

3D printed homebrew dual passive radiator minisub. I love the immediacy of 3D printing!
Photo of the dual pr minisub on a shelf with two 3D printed open-back infinite baffle design full range speakers and a mini amp. CAD design of dual passive radiator minisub showing the two side ports and the port on the bottom for the sub and the round feet to keep the sub from touching the surface it rests on. The compact design is half cube, half cylinder. Photo of 3D printer printing the dual pr minisub in peanut colored plastic, showing the partially printed tree supports inside.

These 3D printed speakers are simple, but get the job done. It feels good to make stuff I can use.

Photos of the box with the trees removed, the mini sub installed, and the passive radiator unstuffed.
My hand holding the speaker box showing the 5” sub. The inside of the box looking from the side where the passive radiator will be mounted. Brass thread inserts are visible, pressed into the plastic. The 5” mini sub has a neodymium magnet to save weight. My hand holding the speaker box. The top of the speaker box has combo terminals for wiring and the words BASS CUBED are recessed into the plastic.
