#39C3 is about to be very.. Cool

hello yes my copper planes are roughly circular with an area of 15393804123 micrometers^2 and a dielectric distance of 0.0000000000000000001585506 light years what is their capacitance please

This pedestrian bridge between a parking garage and a Home2 Suites by Hilton does *not* need to go this hard.

Fibonacci256 Expanding is now available! This morning I'm experimenting with using laser cut and etched black MDF wood for the back panel, instead of acrylic. lectronz.com/products/fib...

8675309 is prime, and so is 8675311, so if you ever need a middlin'-large pair of adjacent primes to test your cryptographic suite, all you need is a 1980s earworm and a +2 and you're all set.

they are having a conversation about listening

source for the hexa and penta now have basic readmes! fresh clones should build correctly (after a submodule init) github.com/starduststor... github.com/starduststor...

thank you for making this possible, Sequoia ✨💜

271 pixels in 3.9mm hexagonal lattice, self-contained logic and power

wow thank you everyone for such a great maker faire!! it was a delight to show you what I’ve been working on and to meet so many wonderful makers and participants!

“exceptional hexagon behavior”

you know, if you give it enough current, an LED bulb can be briefly used as an incandescent bulb

programming in C means you will want to put unsigned types in your code because you know when a thing should always be non-negative but then you will regret doing that

must be a morning, i'm so ready for the faire (not ready at all)

ten days to makerfaire let’s goooo

Official RFC 527.

things are coming together

a little more of the hexagon in motion

i am always learning about parts

I recently revamped this art project for a festival that happened a few weeks back. My friends made the structure and interactivity and I did the lights! I really like these aquarium crystals as refracting diffusers!

Biblically accurate ground

let's boogie

Three Sonic Pillars running with CircuitPython. Each powered by a Pico 2W. Distance with Adafruit STEMMA-QT vl53l1x and improved sound with the Adafruit 5102 DAC. I wish I knew more about music & sound to have a range of more pleasing tones but it’s coming together. Also needs diffusion & mounting.

Finally revisiting "Fibonacci256 Expanding"! I found a few working LED PCBs in my stash, finished the #lasercut acrylic enclosure, got it working with #PixelBlaze by @bhencke.bsky.social, submitted for approval on Lectronz, and up for sale soon! www.evilgeniuslabs.org/fibonacci256...

I got my first PCB assembled! Eventually this will run a dome-sized spectrum analyzer with a bunch of LED strips

well it’s got some issues but i can do charging UI now:

I am normal and can be trusted with shapes

my first seven functional prototype hexas in enclosure. i lucked out that seven is a complete hexagonal number. hat tip to @sequoia.farm for help with the front case design!

So in the meantime I redesigned my hexagon controller so that it fits neatly in the corner on the back of the hexa, leaving room for a nice large rectangular battery that can fit compactly inside a case.

The Clean Air Necklace is back and it's got upgrades! 🤩 It's coming with me to @opensaucelive.bsky.social next week, so make sure to come find me if you're going to be there! See how good (or bad!) the air quality REALLY is in San Mateo. 😉

sometimes i feel like there should be some kind of barrier to entry for designing things

if you're curious about the capacitors, they're Lithium Ion Hybrid (super)Capacitors. They're much safer than lithium ion batteries, and have 50k to 100k cycle life (batts have 1k to 10k). I also designed them here to be replaceable in the case one ever goes bad due to shorts or age. #chippydootles

Finished tweaking the map for this cluster of seven x 1" Fibonacci128. Driving it with a #PixelBlaze by @bhencke.bsky.social 1" Fibonacci128: lectronz.com/products/inc... LED Mapper: jasoncoon.github.io/led-mapper

a loud environment. a deep breath.

here’s a picture of it, the colors look much better irl, the brightness causing some wash out. im super excited and happy with these.

new microscope just dropped, here's the ws2812b 1010s. what? the mosfet is messy and appears to have been rotated? no nevermind that it's fine nevermind that now look the pixel package is so transparent u can see right through it

A coworker had the idea of making this resistance decade, then somebody decided to make a whole bunch of them and hand them out at different locations (and at customers). And now the gerber files are available for download! […] [Original post on mastodon.social]

Finally revisiting my open source earring project. These use an RP2040, an IMU, and 38 individually addressable RGB LEDs. They will wrap around a small rectangular lipo cell to provide enough power for subtle lighting effects for one evening. github.com/sequoia-hope...

they call me bendy5

Ye gods these are even more beautiful in person! 🤩 www.tindie.com/products/sta...
