Sixteen Years of Python Performance
I build and benchmarked 17 versions of Python against each other so that you don't have to. Let's compare the performance of every Python version from 2.6 all the way to almost-released 3.13. Spoiler, it's great!

Install Klipper on a Raspberry Pi Zero 2
Running Klipper on your 3D printer requires a Linux server connected to your controller board. The Raspberry Pi Zero 2 is a great choice. It's tiny and uses hardly any power, which makes it easy to add to your build. If you don't mind the WiFi networking and have $15, pick one up and follow along to get it set up!

Doctests & Metaclasses & Multiprocessing, Oh My!
I've been programming in Python for more than a decade, but it's only now that I have had to bring out the big guns: writing a metaclass.

RErename
My little bulk file renaming script. Inspired by the venerable rename Perl script, my version uses Python regular expressions and focuses on safety. That's not just important, it's super-duper important! Bulk renaming is dangerous enough, but add regular expressions into the mix and It's all too easy to shoot yourself in the foot!

Childrens' Game to Punish PCs
Snakes and ladders is a boring game. But just how boring, exactly? Is it possible to bore a computer so much that it self-destructs? Let's try it and find out...

In-Progress

Greenhouse

For Mother's Day this year the kids and I picked up a kit set greenhouse from our local Costco. Our dog Teddy (I can't believe he closed his eyes for the photo) helped me unpack the boxes today, and I started applying the stain. There are a lot of pieces of wood to work through!

Cantrips

Helpful little single-file scripts. They're more than an bash function or an alias, but less than a full grown-up program. Some are a bit rough around the edges, but nonetheless I use most of these daily. Perhaps you'd like to too?

Tarmo5

Would you download a car? Would you print that car? Of course I would! https://www.printables.com/mod...

Hadley Telescope

Open Source 114/900mm reflector telescope. https://www.printables.com/mod...

Mini 286

This is one of the coolest Raspberry Pi cases ever. https://www.printables.com/mod...

Bear i3

This started as a frame upgrade to first 3D printer, the very poorly chosen ANET A8. Literally no original parts remain, but upgrades continue.

Rook 2020 MK1

Another 3D Printer? Yes, but this one is cheap. And 3D printed. And small too. I've got room for another one, right?

Finished

GPS NMEA Parser

Parse various types of NMEA sentences from GPS receivers. As much an exercise in the Python data classes, introduced in Python 3.7, as anything else.

Beehive Stand

We could put our beehives on the ground, but in the wild they build high, up in hollow trees, away from the damp. Besides, hive boxes are heavy. Picking up 30kg from ground level is no fun at all.
