I have several Fibonacci1024 section LED PCBs, but not a full set. I will likely not be ordering more until the current tariff insanity stops (if ever), so I'm engraving & cutting acrylic to make them standalone pieces. Let me know if you're interested.

This is the beautiful carcass left behind after laser cutting the Voronoi grid for the 320mm Fibonacci512.
Photo of roughly 512 individual facets of shiny black plastic in a Fibonacci / Fermat spiral pattern, like the seeds in the head of a sunflower, all sitting on the black metal honeycomb bed of a laser cutter. A hand can be seen in the lower left corner.

You can 3D print your very own mini cartridge, or DM me and I'll send you one. 😁

I had my local Fedex print the labels on sticker paper. I also made stickers for the PCB and contacts, rather than 3D print them.

I've been printing these brilliant mini NES game carts with embedded NFC tags. Tapping the cart with a phone can be set to open the game in an emulator.

Photo of eighteen small 3D printed Nintendo Entertainment System game cartridges. The carts are gray plastic with color printed labels, contained in black plastic 3D printed covers. A US quarter coin and yellow number two pencil can be seen, included for scale, to show just how small the carts are. The cartridges in the photo: a gold Legend of zelda, Super Mario Bros, Super Mario Bros, 3, Duck Hunt, a gray Legend of Zelda, Super Mario Bros / Duck Hunt, Metroid, Teenage Mutatnt Ninja Turtles 2: The Arcade Game, Battletoads, another Super Mario Bros, Tetris, Teenage Mutant Ninja Turtles, Mike Tyson's Punch Out, Castlevania, Excitebike, Super Mario Bros 2, another gray Zelda, and Kid Icarus.

My very first Black Friday purchase today was from @nervo.us, a brilliant small business that makes these incredible generative laser cut wood puzzles!

Yes, I think this should do very nicely indeed.

Fibonacci182 Cards are now available! In the first pattern (Attractor) long-touches on the pads change the center of gravity orbited by the two boids. A double-tap of the touch pads changes to the next pattern. Running #FastLED on the onboard @adafruit.com QT Py SAMD21.

Check out the GitHub star history for the FEX project. That spike is when Valve announced the Steam Frame, which uses FEX to run x86 games on the ARM64 hardware. 😲

I'm selling my Flux Beamo 30W CO2 laser cutter, rotary, autofocus, diode laser addons, 4" fan & ducts. Asking $1,400, local (Kansas City) pickup. Used but good condition. Paid $2,800 new. I've bought a larger one. I'd love to keep it, but don't have room.

Backup arrived, giant new laser is all set up. It just *barely* fits on the table.
Large black metal box laser cutter with a clear window on ti, sitting on a table. On the wall behind it there are three large black discs that are all displaying the same pattern of bright green circles. To the left side there is a black inline duct fan with black ducts connected.

The delivery driver got the giant laser cutter box into the garage with a palette jack. I managed to get it from the garage to the base of the first of two half flights of stairs with a small dolly, but no further. Will wait for backup. 😅
Photo of a very large box (1240 x 800 x 410 mm, 48.8 x 31.5 x 16.1 inches) sitting on a tile floor at the base of a half flight of stairs. The box has the words "FLUX HEXA" in large bold letters on the side.

Actual label on my laser cutter. 😅
Thankfully it's really quick and easy to do on the Beamo.
Photo of a label reading "ADJUST FOCUS!" on a black metal box laser cutter. The laser cutter head and mirrors can be seen through the translucent orange acrylic cover.
