88 gamers got assistive devices FOR FREE through thecontrollerproject.com either directly from me or through one of the amazing volunteers around the world. thanks to @prusa3d.com for his support with reliable 3d printers and to @cookiecad.com for beautiful filament to make these look amazing.

I finally decided what I want to make with my Linden Oak. And I barely have enough material. Stay tuned for more. (The Linden Oak was a 300+ year old tree in Rockville, MD, that had to be cut down. I bought a slab of it in the county's urban lumber sale a couple years ago.)

Learning Rust's nalgebra crate thanks to Advent of Code Day 10.

I'm a fan of the PrintKit kits. This particular one was a lot of fun. It's nice to see West3D making these available.

I just saw where Trump thinks the US should rename (American) football so that we can start calling soccer football. This, because he was awarded the inaugural FIFA Peace Prize. So ... hear me out ... The inaugural SI Metric System Peace Prize.

It's family wreath laying day at Arlington Cemetery.

I just completed "Cafeteria" - Day 5 - Advent of Code 2025 #AdventOfCode adventofcode.com/2025/day/5 I didn't even get a chance to look at this yesterday so I had two challenges to tackle today.

Is anyone I know here planning to attend the Rust NYC Unconference? I got a last minute invite and booked my travel so I'll be there tomorrow. It would be really nice to meet in person if we have the chance.

I just completed "Lobby" - Day 3 - Advent of Code 2025 #AdventOfCode adventofcode.com/2025/day/3

I just completed "Gift Shop" - Day 2 - Advent of Code 2025 #AdventOfCode adventofcode.com/2025/day/2

I think we underestimated this tree! We went to a cut-your-own tree place and chose this one. It's easily the biggest tree we've ever had. The second pic shows an old bird's nest that was still in it before we cut it down.

Happy Thanksgiving everyone.

The plywood bumper saga has concluded successfully. These were more work than I bargained for but they turned out nice.

Update: I found the time and energy to move all the stuff. But the sheet of plywood turned out to be a sheet of insulating foam. I'm out of luck.

I need to make some bumper frames for the HS robotics team. So I need a sheet of plywood, which I have. But it's buried so deep behind machines and other stock that it feels easier to buy a new sheet.

I think if I wait just a week or two I can check the "uses Rust at work" box. Cross your fingers for me.

Dammit! The bit slipped, going too deep, and broke off.

I'm made of stardust, but I still have to do chores.

I'm happy to report the battery replacement surgery was a success.

I've been dialing in CNC settings to prep for FRC build season. The issues I had with too-small bearing holes are solved. I had to adjust a couple bit diameters (due to wear?) and change the max deviation setting from 0.05mm to 0.01 mm on the onefinity CNC.

Looks like it's that time again.

I've got some reading to do.

I got nothin.

Oh, that's the good stuff.

I see we're inflicting NFL football on the Euro zone today. Here's a tip: if the refs call a penalty for "illegal formation" just go with it. Don't ask what that is. Nobody actually knows.

What a great day for the Owl Moon Raptor festival at Black Hill park. We got to see a red tailed hawk and this Saw-whet owl released from rehab.

This looks like a really great tool!

Just FYI, A couple black holes merged.

Dammit.

Liberals when candidates defend trans people: "We can't do this, it's too unpopular." Liberals when candidates have a nazi ss tattoo: "it's ok, not all candidates are perfect." Do y'all hear yourselves?!

Hello, friends! After 10(!) years of #AdventOfCode, I've made some changes to preserve my sanity: there will be 12 days of puzzles each December (still starting Dec 1) and there is no longer a global leaderboard. Read more: adventofcode.com/2025/about#f... adventofcode.com/2025/about#f...

This was a fun build when I made mine.

I do recommend people follow Cathrin. Her art is amazing and beautiful. You'll also get glimpses of her amateur astronomy adventures.

I just completed all 25 days of Advent of Code 2024! #AdventOfCode adventofcode.com Finally!

One reply and 544 reposts. Nobody knows how to deal with this truth.

I just completed "Crossed Wires" - Day 24 - Advent of Code 2024 #AdventOfCode adventofcode.com/2024/day/24 Interesting: I thought I had a solution by hand a couple days ago, but once the computer algorithm was done, it found mistakes with my first solution and found the right one.

We have finally released our new puzzle, the Flummoxagon! We've done more tweaking and playtesting on this than any other puzzle, and I think we've managed to make a unique and addictive game. It's turned into something completely different from our original idea n-e-r-v-o-u-s.com/blog/?p=9827

It's about time for my annual re-watching.

Tonight, at 10PM Eastern, @pezliz.bsky.social and @zombiehedgehog.com will be taking a look back at 3D Printopia as they walk through my photo gallery from the event. Come hang out with us on Twitch: www.twitch.tv/pezliz

I was working yesterday on my 2024 Advent Of Code. I never finished Day 24 or 25. After developing what I thought would be an efficient solution to Day 24, it didn't work. So this morning I started looking over the problem with pencil and paper and solved it without writing any code. Oops.

Hey! The #RustConf25 talks are now on YouTube. I can finally watch the presentations I missed. www.youtube.com/@rustfoundat...

Two puzzles I'm building: 🔴 12 pieces slide into a cube with coordinated motions in 2D abstract space. 🔵 30 pieces form a dodecahedron with 4D motions. Inspired by John Kostick's designs. john-kostick.github.io/vzome-sharin...

My Lucky 13 Dragon by @lucky13toys.bsky.social (I lost one joint ball and couldn't connect the hand!) Prusament PETG Anthracite grey, Polymaker Hedgehog Makes red, and Protopasta Blood of Mine Enemies.

3D Printopia fans, the photos are ready: davewheeler.smugmug.com/3DP/3D-Print... And, FYI, The Zee and Zed show are going to do a walkthrough of the gallery on Monday, 10pm eastern time. Join them on Twitch as we all take a virtual walk through the show one more time. PS: See FAQs below.

Today is Gabe's, @lucky13toys.bsky.social, birthday! This fellow is an outstanding community member in the 3D printing world. His designs bring joy to everyone who sees them. Go buy one, download and print it, you'll be glad you did.

Probably salvageable but I'll put this roll in the dryer before I use it again.

Coming soon: 3D Printopia photos.

So, I'm using Word to develop my resume and it's flagging numerous words as typos. When I right click, it suggests Spanish words and spellings instead. Why does Word think I'm writing in Spanish? (And will I end up doing my resume in Obsidian with markdown?) Stay tuned.

I've had three big issues messing with me this week. (In addition to the dumpster fire that is US politics these days.) And I feel like I need to just dump it into a thread. Just to warn you, there's no fun programming, 3D printing or photography posts ahead.
