9 Cool-S arranged on a printer plate

Updates from the Cool factory

A Cool-S illuminated by LEDs in the white portions in one half pink and one half blue. It is worn around the neck with a golden necklace.

A white PCB in the shape of the Cool-S. It has a string of SMD LEDs following the shape of the S on the middle portion. On each flat side sits a right angle button.

#39C3 is about to be very.. Cool

TIMON I'm completely serious, we can overnight this to you, though you may have to provide your own chain to hang it on 😅

Also, I nearly fell out of my chair when you showed up in the Any Austin Skyrim tree video!! You were way more of a surprise guest than the "real" surprise guest!

My LIR311s just arrived! Let's figure out that jumperless test rig soon

Magnifique!

Ok but seriously, what am I going to do with a nearly 4-foot-tall (114 cm) Cool S, I've run out of wall space for such a thing.

Do I let it into the blank wall space I keep for professional video calls? Do I mount it on the ceiling over my bed??

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 am crying a lil, this is the only iron I had during lockdown and it has seen me through so, so many jobs since then

A poster board with a meter-long cool S marked out with blue tape and addressable LED strips

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.

One 90° connector PCB soldered cleanly to two LED strips

Oops, I gave my strips a pitch of 2.54mm and these LED strips are 3mm pitch. It's manageable, but I need a quick way to adjust that in the KiCad model.

Reminding myself to quadruple-check the polarity of these strips before turning on the iron.....

I love you, Hakko B2300 Heat Resistant Pad

The Cool S diagram from the last post, with gold corner bracket pieces laid out around some straight sections of addressable LED strips.

A hand holding a printed out diagram of the Cool S shape, with distances and angles dimensioned. It is not a cyanotype blueprint despite what the post says.

....oh right, I completely forgot about these until someone asked me about them at Supercon and then a lot of people asked for a set.

Honeycomb pattern, one of the preloaded ones on a Pixelblaze LED controller by electromage @bhencke.bsky.social

Alpenglow Industries (Carrie) (@alpenglow@mstdn.social) Attached: 1 image Got an ugly-ass nonfunctional fireplace that someone painted black? I’ve got the solution! I’ve had the parts and custom flex boards for a while for this and just no time. Tonigh...

I made a really cool LED wall project for my house last week - spruced up an ugly black fireplace with 1035 LEDs and a Pixelblaze LED controller. Check out the full story and project progress on mastodon:

You can tear them at angles of 90°, 60°, 45°, 30°, 22.5°, 15°, or combinations thereof.

(....ignore the Jokerman silkscreen, it's fine don't worry about it)

A flex PCB with concentric copper rings and perforations so it can be torn into smaller arcs and wedges.

The same flex PCB with one quarter of it torn out and turned into three curved connector pieces of different radii. The remaining board has a silkscreen that says "Do it [...] coward" in Jokerman font.

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 made this specifically for @settinger.net but felt I couldn't deprive the rest of the internet of this nonsense.

The finished panel of recycled plastic tiles, framed in a shadow box

The canvas from the previous post, now fully tiled on the top half. A hot glue gun is lying on the empty bottom half. A 5-foot-long continuous coil of hot glue stick is spooling out the back of the glue gun.

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'm so glad I'm not the only one!

A stretched canvas with some of the homemade melted plastic zellij tiles nestled in place, starting at the center and progressing to the top left.

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.
