Scorched earth soldering

Stock photo of a soldering iron with a glowing red tip poking at a melted board.

"Hey let's make sure this stock photo hand model doesn't make us a meme and hold the soldering iron by the metal bit by just turning it on for the shoot and setting it to a bajillion degrees."

No, not really. All it takes is a single clock cycle call before and after to enable and then disable the input, no big deal.

If you are at @bsideslv.org this week and enjoy my open-access writings on the Jumperless hardware developed by @architeuthisflux.bsky.social, be sure to check out the raffle and silent auction. I've donated a Jumperless to both!

www.jrpanel.com Okay turns out you can just get membrane keypads made for crazy cheap. I always assumed you could (and probably still would ask Elecrow to deal with them on my behalf), I just didn't expect there to be a JLC-style online ordering setup.

Now I need to come up with some silly nonsense

Output from me trying to get jumperless to work with pulseview where the upper bits from the analog measurements are missing, looking like a cross section from a frensel lens

Wait, are Frensel lenses just sine waves with the upper bits missing?

I learned two new techniques for customizing 3D models: cutting the model and dropping it through the build plate in the slicer software.

I mean, I do have a box of shotgun shells I cut open to harvest the lead shot. It would be very fitting to use every part of the animal.

I hereby nominate @straithe.com for inclusion into your Maker starter pack.

Haha yes, it very much is EE code. I would love any help you can muster, especially now that it's starting to spill over from "firmware for some electronics thing" into a full blown operating system.

Two circuit boards are connected to the Jumperless breadboard. The Jumperless breadboard uses LEDs to highlight connections rather than physical jumpers.

Thanks for writing the docs for the OG I never got around to condensing into something approachable. Your posts are so much better than the scatterbrained nonsense I wrote. (I even changed the link on the probe kit to your writeup.)

I've got a new open-access post up on my Patreon about the user interfaces on Jumperless. Please check it out!

The jfs module is basically like MicroPython's vfs and parts of os, but kinda written in a style that's probably more familiar to Arduino-style C++ people (me). It uses the almost standardized API shared by FatFS (the one Jumperless actually uses), LittleFS, and SDFS, but still has been Pythonified to use types that are easier to work with in MicroPython.

I'm getting confident enough that the way python does certain things is garbage for my particular needs and that I can shove the C++ API into Jython (in this case they're pretty similar but I get the feeling this is a gateway drug that ends with a new Arduino C++/Python mashup language.)

Okay I think it was worth the better part of a day, but the jocs website now (mostly) color matches the MicroPython syntax highlighting on the Jumperless.
And I added some new stuff about jfs (Jumperless File System) and generally made everything prettier and like ~10% more helpful.

That's cool, you can just select 15% if you don't like it

Someone tipped me on Ko-fi immediately after opening their Jumperless V5 and it gave me the most hilariously dystopian idea.

I think what you're smelling is cigarettes... and dreams.

@ArchiteuthisFlux My Jumperless V5 came, it’s beautiful and smells like cardboard and dreams.

It's funny I didn't even really think about it, but you're right that basically every step in the probe build is some completely unhinged technique I just made up. Probably should've provided better guidance than like 10 sentences on a piece of paper.

I'm so glad you figured all those out and wrote better docs than I ever could in the process. Thank you!

(Now go to your mailbox and get your V5)

The Jumperless probe has some of the most interesting engineering solutions I've seen in a soldering kit.

This isn't at all what he was intending to do, but I was musing about how to make this into a real costume and found the coolest research paper by Disney about designing inflatable structures.

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