Hey @Unixbigot !
I wondered what that multi-microphone home assistant module was as per #EverythingOpen presentation? Went and installed #HomeAssistant didn't I? Can give it up any time I like...

ESP32-S3 based mic arrays: https://www.aliexpress.com/store/1100220184/pages/all-items.html (the one I have is the Korvo-1 but cheaper alternatives exist). You could just meld an esp32 board with a mic module eg https://www.aliexpress.com/item/1005004396761379.html or ( https://www.aliexpress.com/item/1005005449219195.html + https://www.aliexpress.com/item/4000320765322.html )

The wizard had done well at the market, having traded all his fireworks for a brace of smoked fish, a goose, and a small kitten.

Reaching the river he found the ferryman disconsolately sitting on the dock. “Where’s the ferry?” asked the wizard.

“Sunk! I’ve sent the boy for an ox team to pull it out, but he’ll be hours. Rope bridge if you can’t wait” the ferryman pointed at two ropes strung across the river.

The wizard considered…
”hmmmn I can only carry one item at a time…I know this one…uh, kitten first, then um”

There was a pricking at his ankle. The kitten was climbing his leg. “I got this mister” said the kitten when it reached his chest. “You take the fish and I’ll ride the goose”

“You will make a powerful familiar”, complimented the wizard.

“Off you go boss” said the kitten, jumping to the ground, and mounting the goose.

The wizard took the fish in one hand, grasped the upper rope in the other hand, and stepped onto the lower rope. Gingerly he crab-walked across the rope bridge. When he was midway across the kitten set sail, prompting the goose into the stream.

The goose paddled strongly, catching up with the wizard midway.

“Capital!” called the wizard, then “wait, what?!” as the goose changed course and paddled downstream.

“So long, sucker!” called the kitten.

“Hey Bud, did you see on the teevee they reconstructed the face of a Neanderthal skull?”

“Yeah it’s bullshit. If there were Neanderthals around today, you wouldn’t be able to tell them apart from anybody else”

“What do you mean?”

“Like, say there was this one Neanderthal who didn’t die, he just kept going, and he was here in his car with you working as a Repo Man. You wouldn’t have known”

“Hypothetically?”

“Not at all.”

“Intense”

@decryption@aus.social avatar

any of you nerds seen an ESP-based relay board that'll handle 24V AC and also take input from a physical switch?

Unixbigot,

@decryption yeah can do that for you with pluggable modules. Two column module baseboard, relay module on the left, cpu and button modules on the right.

Unixbigot,

@decryption Oh this is for your hvac hack? I have another esp32 module in my stable that’ll drive four or 8 way relay boards.

Unixbigot,

@decryption let’s work backwards from the vent motors. Are they really AC? Are they just on-off or do they need to be reversed? That’ll determine what kind or relay you need. I also have a shit load of 4-gang solid state relays that are good for AC (they don’t work with dC). Driving relay banks is such a common pain that i designed a relay bank driver that stacks up to drive an infinite number of them, 8 per level.

Look, I know it’s stupid but if you have a synthetic rabbit in Queensland you should NOT connect it to the wifi. They passed the synthetic rights law just fine, meaning synthetics of all species have the same rights as organics, but they neglected to amend the classification of rabbits as prohibited vermin. Rabbit detector van swept up our Josie’s beloved Flopsy and she’s utterly inconsolable. We restored a backup to a new chassis but she spotted the difference immediately and now she won’t come out of her room until we get the original back.

I've implemented a KiCad footprint that provides an "oh fuck I got tx/rx backwards again" crossover box. Not my idea but I forget where I first saw it (I think it was here on Fedi). Fit two resistors (or solder bridges) horizontally and it's straight through; fit them vertically and it's a cross-over.

https://github.com/accelerando-consulting/Kicad-Libraries/tree/master/Accelerando.pretty

A kicad footprint that is two resistor footprints, where the resistors can be fitted vertically to swap two lines, or horizontally for straight through
3D render of the crossover footprint, showing that it conceals the fact that you are a doofus who often gets data lines bass-ackwards.

Was I fucking drunk when I designed this board? I completely missed 2 GPIOs to control a LED and a switch on the schematic, and I used the wrong SERCOM for the I2C lines which means I now need to swap SCL and SDA.

This thing is a fucking mess.

Unixbigot,

@jpm i made a kicad component and footprint for swappable tx/rx lines, via clever solder bridges (or 0R) it is called Oh_fuck

Unixbigot,

@jpm what did you scrape that solder mask with, a brick?

Unixbigot,

@jpm on sale today for all your precision bodging needs - a diamond cone can be used to strip solder mask, and to cut tracks. https://s.click.aliexpress.com/e/_mOJpIOO
