Ok, here's two black holes, but I need them back by the weekend....

A Great Crested Flycatcher? First time I've seen one.

Nothing like a little time on the water.

Snow? Anyway, I hope to see you at # RMRRF.

I'm excited for Rocky Mountain RepRap Festival #rmrrf this weekend. Who here on bluesky is planning to attend?

Ooh, irresistible.

Since December I've been working with the Xilinx Zynq platform and trying to get the PYNQ Python/Jupyter environment working. But, wow, it's just been one roadblock after another hitting version restrictions with Vitis, Vivado, PetaLinux, Yocto and PYNQ. (more)

This is the fifth time I've run this particular CNC job with no issues but this time the bit breaks? Never trust a CNC machine.

This 5-year old Makita router that I use on my CNC has never had any maintenance. Today I want to try and replace the brushes and bearings. Old vs new brushes pictures.

The odds are stacked against me already so you might as well donate to MPLS rent relief and use the receipts to win the knit mittens, too.

I'd like to start documenting some personal projects so I'm wondering where people create such blogs these days. Any recommendations?

It's so hard to say or do anything productive today.

I remember 1976, the USAs bicentennial. I did the math and figured I'd probably live to 2026 and America's 250th birthday. Well, I made it but ... things feel off.

I want to take this to heart.

I said goodbye to 2025 by marking every Discord server as read. There's no turning back now.

At the end of the workday yesterday, I was downloading a software package, estimated to take 7.5 hours. This morning it reports a failure and I'm now starting over. Oof.

The new leaf I'm hoping to turn over in the new year is to share more electronics and programming projects. I feel like having a portfolio of shared work will be very helpful. But I didn't get this started over the holiday as I wanted to. Maybe just posting my intentions will help?

Articles of Impeachment would pass today as easily as the Epstein Bill. Do It.

Impeach Him. Do it today.

If you don't follow @oddjayy.bsky.social, I recommend him. Especially if you like robotics and mechatronics.

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.

My most-used words in 2025: 1. "robotics" (16×) 2. "team" (16×) 3. "couple" (16×) 4. "cobs" (15×) 5. "weekend" (14×) anisota.net/harvest

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.
