Pure OpenSCAD one-day project: I made these chunky blocks for learning the letters in the Mongolian script. There are a lot more glyphs than just these ones, so I want to make a little Python wrapper for an OpenSCAD command-line call next. Many more glyphs to generate, but it's mostly automated!

I missed my monthly "don't buy a resin printer" meeting with @jumperless.org because I was hand-soldering a 3×2mm WS2811 IC to a flex PCB. If you want a Neopixel with colors other than RGB, turns out you can just make your own by having a long enough manic episode.

Petition to give the LA Metro A Line a secondary name, the "Jonathan Gold Memorial Line," so we can all go back to calling it the Gold Line and end this song-and-dance where I have to suss out how long you've lived in LA before I know which name to use around you

I caved and moved my nice Hakko again onto my living room floor where the Cool S is happening. Back in business. These angle connectors are great!

I remember these being easier to lay out in elementary school 😅 Anyway, good thing I didn't solder any more joints because I realize now I should have the data flowing in the opposite direction. Got to reverse all the strips now.

This project brought to you by the Hakko B2300 Heat Resistant Pad I love you, Hakko B2300 Heat Resistant Pad

A silly idea that turned out well! Most flex PCBs are cut by laser, not milled, so you can make perforations by adding incomplete edge cuts. These disks are for cleanly joining LED strips at different angles and different radii, and they break apart with just my fingers, no other tools.

I have enough pieces to fill an 11×14" shadowbox now. It's all coming together 😁 I'm still a bit worried about fit and precision (or lack thereof) on these tiles, but gosh they fit nicely so far. Need to get more hot glue though.... So that's *two* things I had to buy in order to complete this.

Taking a break here. One of the black-red-purple convex hexagons and one of the burnt-white concave hexagons had to be filed down a wee bit before I could slot them in. I love the 5' continuous glue stick 🎵

I made some high-temp silicone molds out of Mold Max 60 and have begun casting Moroccan-style zellij tiles out of my years of accumulated PLA scrap. They are very fun to play with.

Our #makergiftexchange happened on Wednesday, another moment where I'm bowled over by just how creative my friends and colleagues can be. My contribution was an inside joke. Did you know that, in Shenzhen, they'll let you print whatever you want on those shiny holographic security stickers?

And thank you @lasermistress.bsky.social for making the PNG that got sent to me in the first place!! <3 <3 good teamwork everyone, it was SO HARD not to tell y'all about the sticker machine before the gift exchange

It wasn't till after the event that inspiration struck and I made this spool holder. It's got a post in the middle to hold the Pathé-Baby center alignment holes and lets you tear the sheet at the right spot.
