Just another day of coming up with new ways to shove Jumperless branding into every square millimeter of this thing for no reason.

@secretbatcave @settinger I hadn't thought of it that way, but yeah, I guess it is.

A quick self-nerdsnipe. Someone should do something with this Amprobe Recording A.C. Volt Ammeter to make it draw arbitrary images, but that person should *definitely not* be me.

Maybe @settinger should swap out the thermal printer in his capybara head with this.

@shapr Then you're gonna *love* my eventual pivot into making blockchain-enabled AI pins!

Ha found something, a **Very important** addition (sarcasm), that little tongue on the bottom left covers the crystal, so you can't freeze the RP2350B by holding it in a weird way and placing your finger on top of it (or: why most consumer electronics have an enclosure.)

Someone please lie and tell me there's absolutely nothing that could possibly be improved so I can move on to the rest of this thing.

Oh, if you wanna zoom around and look at the schematic and stuff, here's a link to the board in @stargirl's KiCanvas.

It's fun to be the board that has so much going on that it's basically a stress test / performance benchmark for things like that.

I paid for this goddamn copper, you can dissolve it from my cold, dead fingers!

PCBs... uh... are like onions.
Because they make you cry?

Me: **really needs to get these V5 Rev4 gerbers in like yesterday to get them shipped before CNY**

Also me: **spends 3 days nudging tracks around purely for aesthetics (yes, including the inner layers because fuck you)**

The thinking is that they'll all come with some resin printed one, and I'll send people who do rad shit another one made out of some metal or whatever. These things are tiny, so tungsten/osmium/uranium/gemstones aren't even necessarily off the table.
The best part is the act of forgery is itself worthy of getting one, so they're literally impossible to "counterfeit", aha!

Youguise, I think I just figured out an awesome way to thank all these non-monetarily-motivated, Star Trek-ass, commie bastards in my community for their contributions to Jumperless V5.

It's been a really long time since I've pulled off routing a board on 2 layers. The difference in cost for 4 is practically a rounding error, but it's totally worth it for the 丂 ㄒ 尺 乇 乇 ㄒ 匚 尺 乇 ᗪ, which is clearly the whole vibe here.

omg this little GPIO/analog/QWIIC/Bus Pirate breakout board that plugs into Jumperless V5's (new) FPC expansion port is finally done!
I seriously could've made this ugly in like an hour. But noOoOo, I just *had* to spend 3 days making this free bonus board into a friggin' work of art.

I need a shorter domain name because I traded a Jumperless for a custom deadbug LED QR code business card at #supercon. And architeuthisflux.com doesn't quite fit in the smallest QR code.

There's a whole backstory for how we got here, but I think this one from our recent meme-fight is better without context.

Lonely sausages aren't an excuse, written in the legendary font no one remembers, Jokerman. Get something similar to this on a shirt from Claire's Threadless at some point. But for now, send it to that one friend who is always in some whole dramatic situation just because he's a fuckboy and cannot control himself and you have to try to sound sympathetic even though it's clearly their fault and they need to grow a frontal lobe.
