Here’s how Fluxer plans on doing it: fluxer.app/blog/roadmap-2026#why-polyproto-and-no…
Okay so let's write this down to think it though.
The latest smoke detector to howl pointlessly into the night sends out 11.3V DC onto the signal pin when triggered but running off batteries. I suspect that's 12V nominal, and it probably delivers 12V when operating on AC power.
Most importantly, it's not like... 500mv. Or AC. Or complicated. It's simple DC.
When acting as a non-reporting _satellite_ node, it triggers when _receiving_ 4V DC on the signal pin (4.0 exactly), and that voltage is polarity sensitive. -4V doesn't trigger the alarm.

Checking for DC on the signal line, I get functionally nothing. 20ma DC at most, and even that's something I'm picking up out of noise floor shift rather than direct measurement.
My _thought_ was that if the signal line was somehow floating in whole number volts (for whatever reason) than maybe somehow the right RF noise could kick it over.
The problem with _that_ is that I can now _also_ confirm that non-detecting units go off _exactly as long_ as a detecting device keeps saying it's detecting by putting voltage on the signal line. If that voltage goes away, so do the satellite alarms - and immediately.
And that's not what happens. We have to manually intervene and shut the alarms off ourselves.

All _that_ does is get us right back to where we started, which is, "we have alarm after alarm after alarm of different makes, methods (ionisation, photodetector), and models which just in this house are determined to go off randomly, usually but not always at night, for absolutely no detectable fucking reason, and then pass self-test just fine afterwards."
And no, regular cleaning - even weekly cleaning - does not help. I do _all the things_. None of it stops the problem.

If you're new to this adventure, I have heard this exact same story from _many other people_ at this point - though nobody I've talked to has said they've literally taken metres to the signal wires to verify that way.
Regardless, I know it is not just us.
What I've been told from others who deal with this is to RMA individual units that trigger randomly one at a time until you end up with a set that doesn't. And I guess that's what I'm gonna do, but
holy shit, team
holy shit

Tak, nadal myślę, że Toy Story 5 to po prostu boomerskie komiksy o tym, że technologia zła, książki dobre, ale ktoś pomyślał, że dobrym pomysłem jest stworzenie z tego całego filmu animowanego dla dzieci...

The most incomprehensible thing about this incident is why Jackie didn't have a rocket launcher with her.

Y’all, someone sent this to me without context, and … I have *so* many questions.

Behold, a cigar box guitar that will cut you (or, realistically, me).
Thanks to @fullywoolly@mastodon.social and @Oyu_Fka@mastodon.social for help in making the piezo pickup work (i.e., you only have yourselves to blame).

Quoting
I've been kind of absent from here for a while. But now! A video of a very bad but very fun guitar! That I made! First one ever!
Materials:
* Galvanized steel washtub
* 2x4 (i.e., wood)
* walnut piece (fingerboard)
* fret wire
* guitar tuners
* rusty bolt
* piece of pipe from a lamp
* floor base of a different lamp
* scraper blade from oscillating tool
* bicycle chain
* luggage strap
* 1/2 inch EMT (galvanized) conduit
* thick wire from a yard sign
* piezo buzzer from some toy
* 1/4 inch female audio jack
* wire, solder, some screws, etc.
(this is 5 minutes of me showing the guitar and playing some random things to show how it sounds)

@oaj@mastodon.com.pl @cazabon@mindly.social Following hashtags on a Mastodon server only shows you tagged content that arrived at that server for other reasons. You don't get all tagged content. See https://tags.pub/#why
You should keep it blocked if you want to, but it does provide a real service.

@cody@catboy.baby I am pretty sure MFM is a feature though: https://docs.akkoma.dev/stable-docs/installation/migrating_to_akkoma/#why-should-you-migrate
if we are talking about things that suck, maybe you're thinking of pleroma?

this is the opposite of fire safety
this is the opposite of how anything like this should ever work, I mean
what if all the RMAs are getting you are a set that won't go off even when they should?
but whelp
guess i'm gonna find out
'cause this sure ain't workin'.
