Cuttlefish plushie in progress. LEDs/electronics come next before it is stuffed and sewn closed, but I had to post now because it's looking so CUTE!!!

@jasoncoon I didn't take it any other way! Jealous that you got the full "lights out" experience

My friend Jens is a 3D printing wizard. This is his variation of an LED ball. It’s better than mine in every possible way. 492 LEDs manually soldered together in 2 halves. Everything clicks together. You switch it on or off with a tiny rotation that triggers a micro switch. It’s gorgeous. @geekmomprojects

2 halves with center assembly with batteries and controller.

@tom_verbeure 😲😲😲!!!

@tom_verbeure it's astounding, but the hand soldering is insane!

@geekmomprojects@mastodon.social avatar

@tom_verbeure yep, that's why I took the approach of just piping the light from the PCB to the sphere surface, because I don't have the skill or patience to attempt that. What you did came out beautifully, though.

Just to see what's possible, I glued 18 WS2812B-1010 LEDs to the edge of a scrap PCB to get an addressable LED strip with a density of 900 LEDs/m. They are slightly larger than 1x1mm, so 18 fit into 20mm.

High density LED strip made out of 1010 addressable LEDs showing an animation.

@maketvee now that you've achieved this impressive milestone, will you try to achieve a (linear) density of > 1000 LEDs/m by utilizing a 3rd dimension?

@maketvee you could make the first no-wire SMD LED cube

@Jorvon_Moss I was sorry to miss it - I always have a conflict. Glad it was fun!

Sadly, I wasn't able to fix all of the flaws (a tendency to explode being the primary one) in my robot, "Footloose", so we won't be competing. However, I'm here at UIUC to cheer on my son Justin and my bouncing 1-lb grand-bot, "Singularity," (pictures below) as well as his team's 30 lb bot "Collosal Avian." The tournament is livestreamed ("Live" link at the "Robobrawl UIUC" YouTube channel) if you want to check it out.

@bytex64 ah, the good old days when insurance premiums were low!

@brokenminded yes almost all kinetic weapons in the 1lb not division are powered by brushless drone motors.

The first post-lunch 30-lb combat bot match ended with an arena-clearing LiPo fire. Clip of the fatal shot here: https://youtube.com/clip/UgkxVVXaJlAKat0wR0-XTPVayp3HUAc8dY0A?si=XkP8xcEOL5CHLaZk Will go back inside once it clears out

@gadgetoid I wouldn't have either, the designers said they came up with the idea themselves, and their execution is beautiful.

The downside of the enclosed combat arena is the challenge of clearing out the smoke. Still waiting at a distance for them to bring in the giant fans to air it out.

geekmomprojects,
@geekmomprojects@mastodon.social avatar

Back in business now with the smoke cleared out. This entire 30 lb fight took less than 10 seconds: https://youtube.com/clip/Ugkx1Cre2CqEpij_SBT2M8OdrIuE8eN_BJcD?si=M1IeAH2EuUAjCp8i

This 30-lb match also ended in less than 10 seconds because one of the competitors destroyed itself immediately before its opponent had a chance to touch it: https://youtube.com/clip/UgkxqV5_pbsZbhBIhK3fB8_QP6QKoOS5BU7a?si=5VUipQIZn7sOw0O0

Here's the bristle bot's (named Surface Charge) second match against a novel vertical ring spinner bot. I was watching while filming so the camera slips upwards a bit, but you can see the devastating force of Surface Charge's weapons in the final hit.

My son's bot, a compact full-body spinner named "Singularity" went up against a Pac-Man themed horizontal spinner. Singularity performed well but lost. It's hard to keep a full body spinner stable, and there were some issues. Still, it is an ambitious, well executed design, and I'm super proud of Justin's work. The tournament is double-elimination, so Singularity will fight again.

Combined video of two very short one-pound fights demonstrating that the match stops immediately once a bot's LiPo battery gets exposed.

Successive clips of two very short fights between one pound robots which both end with the robot shell opening up and the contents exposed.

The 1.5 lb full-body spinner (Wayward) which lost to Pac Your Bags (Pac-Man themed horizontal spinner) locomotes (awkwardly) with a single shuffle drive at its center, which pivots to let it turn. Not sure how it works mechanically, but I hope to find out. The full two minute match is below.

@SnoopJ yep, you never know how they're going to turn out!

Here's a snippet from a fight between a cute duck-shaped bot, whose orange bill is a horizontal spinner, and a vertical spinner whose weapon is jointed in the middle to become narrower and longer the faster it spins. The duck lost an eye early on and ultimately lost the match in a judges' decision, but looked cute doing it.
