I decided to be properly cyberpunk, my bar for Neotropolis needs exhaust fans on the outside. To be cinematic, the fan should turn pointlessly slow.

I bought a fan with a speed controller. It seem to use 5V PWM. Sending my own PWM, ~8% is the lowest speed. Below […]

I wore my Owl head and cyberpunk jacket for the Halloween party at #supercon and a bit Saturday night too. Though I had to keep taking it off to speak to people. At some point I need to add a speaker like those used for some storm trooper helmets.

There were a number of cool badge cases at Supercon this year. @thzinc kinda vaporwave case was really cool in person.

Also here's @geekmomprojects 's Souis Cuitton purse and ageppert's Speak&Spell

Today at #supercon - while the multimeter and bendy and scope SAOs were the most impressive last year, this hedgehog that @mitten made was my favorite. And now I have one!

(I've been thinking a bit about SAOs / badges. Something like a pocket operator would be a […]

Best outfit at #supercon last night IMO - @securelyfitz - above the buttons are paper displays that change questions, and when you make a choice, it takes your picture and prints out the meme with you in it and the questions you were given.

Latest creation: KPop Demon Hunters light sticks. @xconstants.bsky.social suggested them so she could greet Huntrix / Saja Boys trick-or-treaters as their fan.

Laser cut acrylic with edge lit LEDs.

At #burningman this year, I brought a small 1200 lumen projector that I could mount on my bike. Would it be feasible to do some quick on the fly projection mapping? It seems that yes, for somewhat small (about 6m x 3m max for reasonable brightness) and not very […]

Got self-written drivers for the GP1294AI VFD display working.

There's an existing U8gr driver. I now have it working with Adafruit_GFX (with a GFXCanvas1 buffer) and with #rust embedded_graphics via CCanvas.

Unfortunately neither framework seems to support […]

As we prepare for colorful explosions, I remembered I wanted to share colorful lasers + confetti I saw a few months ago at Gareth Emery's LSR/City show.

I have a singular RGB laser with ILDA interface + USB DAC that I've played with a little over a year ago. Someday I'd like to drive it with code.

found photos I took that night

This draws a lot more power than any of my wearable LED projects, and 4 hours later my shoulder is still reminding me of the weight of the battery pack. I used a 130Wh Paul C. Buff Vagabond Mini pack. It lasted about 2.5h. (this would use less power if the […]

It has become relatively easy & affordable to put together an LED Matrix sign. Recently I put together a 6 panel display using 1/8 scan modules for something much brighter than the 1/16 & 1/32 scan modules I usually use. It's bright enough to carry around in high […]

Here's an example where the columns are orange & teal instead of white.

Result of many months of work - over 15,000 LEDs to make a dim room.

The triangles on the front are segments of 32 addressable LEDs, but were just solid white most of the time. The window clock is commercial sheets of WS2816 driven by Novastar drivers/processor […]

Yesterday I went to a mad scientist meet up.

Unfortunately, while I did have a sign, before heading out, I realized it was unreadable without shade. The location was a large plaza at noon. So in the end, I had nothing more than my presence.

I expect there will […]

Also made a virtual 3D Christmas tree in the volume

@themariday I did try the "hardmode" setup, and the mapper did have more difficulty. It kept seeing reflections and deciding the pixel was somewhere inbetween the real LED and its reflection. The solution was stopping down the camera's shutter speed a lot. Then […]

Inspired by @geekmomprojects 's friend's tree, I tried out @themariday 's mapping tool a few days ago.

This is a setup I put together for testing a tool I was working on years ago, and it managed a pretty good map (only ~4 notably misplaced pixels). Maybe I'll […]
