New modules and old modules for the Heathkit AA32, front and back.

Guess which are old and which are new.

The final stage of my rainwater filter system is a UV disinfectant. The control module has an indicator for "lamp good" and "lamp bad," but the whole thing is in a shed outside. I plan to use an ESP32 or something to monitor and alert me in case of failure.

How should I detect a failure?

Most superhero stories are problematic, but this page describing a dilapidated neighborhood as a place full of villains where no one follows the rules is some grade a bullshit gentrifier propaganda

hey - does anyone in berlin want a huge (prints on A2), old, amazing pen plotter? (image of it attached).

i got it when i lived there, and i've since moved and had huge hopes of trying to move it back to nyc but it's just not going to be possible. you can have it for free as long as you go and pick it up at my old flat, it's heavy as shit.

includes all needed cables and a lot of repair / maintenance / operation manuals that don't seem to have been digitized anywhere.

Note to C programmers: char doesn’t default to signed on all systems. Please be explicit in your type assignments. I just spent way too much time trying to figure out why an aprs wx utility that worked fine on my x86 systems failed on beaglebone and rpi.

The ISS equipment seems to be working great for this latest ARISS SSTV event, but I haven't been able to capture a good image yet.

Dear web developers and admins,
please stop embedding Google's hideous #ReCaptcha into your websites. Its algorithm is faulty, forcing regular users to click dozens or even hundreds of fire hydrants, bicycles, or traffic lights each day. It puts a 'suspicious activity' flag on users who won't obey to Google's business model - such as people who don't sign into Chrome, use anonymity VPNs, or use browser extensions to suppress common tracking mechanisms. Enough is enough. Stop it.

I finally got to tell someone off for not wearing a mask today

There’s nothing wrong with building electronics in Tupperware, but you really should consider using this as an excuse to get a 3D printer ;)

I *had* enough cutoff wheels to finish this project before three in a row exploded on me. Always wear eye protection!

I never should’ve let myself get suckered into using a “free” commercial product in the first place. Time to make sure I have local copies of everything in portable formats.

I picked up this programmable color LED sign on a whim because it was free and has a dozen decent power supplies in the box. But if I turn it on and it works, what should I do with it?

Whoah. This is a tough read: tinykat.cafe/on-all-that-fucke

I needed a sheet metal brake to fabricate a custom hvac plenum, so I threw this almost 6ft wide brake together out of parts I had on hand: 2 2x6s, a piece of angle iron, and a piano hinge.

I mean, here you are in a world full of chemical indulgences that can grind your ego to sand, dial your empathy to 11 and fill you with visceral, bottomless bliss and a sense of immediate and universal oneness with every other sentient entity in the vast cosmos and your go-to move is "this made me really give a shit about turning calories into javascript. I created content for 14 hours straight."

A package shipped from Houston on Monday has traveled to Shreveport and Dallas on its way to me in Austin. If you’d told me 4 years ago the president would destroy the postal service to prevent mail-in ballots, I would’ve thought you were a conspiracy theorist.

I just installed FreeBSD on this Dell/Wyse thin-client. It’s a little bigger than my usual utility/experiment systems (BeagleBone Green for scale), but cheaper and so.much.faster. I’m using EOL thin clients for all my future projects
