I suppose you don’t have the original power source, if you did then measuring the output would be my starting point.
If it’s LED then it’ll probably be a single LED using PWM. In that case try figuring out where the switching circuit is.
If it’s not LED, you should measure resistance between the wires, that would tell you which one is the common. .

Well, you want rent money, don’t you? Then keep back the tears and start wriggling those piggies, while telling me a sexy story about how sweaty they were today. /s
Seriously though, just keep a self-hosted LLM for the communications, that way you don’t have to even try to tell the freaks apart. Just make sure nobody tries the ol’ “ignore previous instructions” trick

Buy womens discount underwear, wash it a lot, make sure to tumble dry as well. When it’s good and “worn” buy cans of mackerel in tomato sauce. Smear some of the sauce in the crotch of the underwear. For a premium product you could not shower for a few days and wear it while buying the fish. Maybe forget to shake before whipping your dick back in.
What am I even doing with an everyday boring job, I should be doing this myself.

- Comment on Single ended signal transmission 2 weeks ago:
If you’re designing for production then talk with the assembly guys, they will have options and cost estimates.
If we’re talking a one of, then just try. It’s only 500mm so not that much can happen. Especially at the slow speeds you mentioned. 20kHz isn’t that fast compared to the +100MHz that a cat5e is designed for when using differential signalling.
Are plugs a must? If not I’d consider soldering the wires. At least for testing the cable’s suitability.
If you must use plugs, then don’t use rj45. Some yahoo, like yours truly, will come along and go “neat, an undocumented ethernet capability” and fry something expensive. Have a look around DigiKey or where you get your parts, and find a less common plug.
And if you end up needing more wires, then get an old parallel ATA HDD cable from the early 2000s. They have 80 wires and are free at the dump.

- Comment on Repair or not, electrical heater switching circuit 1 month ago:
A relay would do the job, but they also wear out faster and the sound is noticeable.
While writing that, I found myself thinking about how significant the life span difference is. So I did some back-of-the-envelope calculations.
The defective heater had been installed for roughly 2100 days. Sometime during April we shut the heaters off, and they’re not powered up again until October, so let’s call it 50% of the year. The schedule for the heaters is usually two power on cycles daily. Again let’s call it 50% of the time. The house is pretty OK insulated, but let’s say that the heating element is powering up 4 times each hour. In reality it’s probably closer to 25-30% and twice an hour, so I’ll use that as the lower bounds for this calculation.
1050 days is 25200 hours, meaning that the heaters will have done between 12k and 50k power cycles in the almost 6 years of operation. I’ve seen relays weld shut before 10k, but MTBF for suitably rated relays on RS starts at 50k power cycles.
So maybe a relay could actually do the job. But then there’d still be the issue of the noise, which, while negligible, could still be annoying for some, especially in a bedroom.

Wow, thanks, that is much appreciated. I was trying to find a SoMe channel. And knowing that Adax isn’t averse to support is even better.
- Comment on Repair or not, electrical heater switching circuit 1 month ago:
I could rewire the heating circuit, but doing so without the backing of an authorized electrician would be illegal. I’m already on thin ice just installing the heater by self.
But the thought has crossed my mind, as I have noticed there being an order of magnitude more 230V heaters on the market than 400V. On top of having to rewire everything, I’d have to put in a new 3 phased breaker, otherwise I’d be pulling way too much current… Let’s just say that this 1200W heater isn’t the only one we have in operation in my house.
- Comment on Repair or not, electrical heater switching circuit 1 month ago:
But you managed to pack my thoughts into 3 sentences. Unfortunately that means a new heater, because I don’t have a source for the board.
- Comment on Repair or not, electrical heater switching circuit 1 month ago:
I was thinking about contacting the manufacturer, but they don’t really have any post sale customer support. That’s all on the stores, and besides the heater has been in operation for almost 6 years now. So I’d they’d tell me to go away at best.
- Comment on Repair or not, electrical heater switching circuit 1 month ago:
I don’t know what stopped it. I wrote the occupant, but it was really just me. Neither RCD or fuses were blown. There’s a fuse (bimetal in a plastic box positioned above the heating element inside the heater) in series with the heating element, but that’s 400mm from the short, and its probably only there to prevent overheating and setting clothing coverie the heater on fire.
A new heater is 200€, because it has to be 400V as there’s no neutral wire available. That’s why I’d even entertain the idea of repairing the board.

I didn’t notice the USB port on the right, I was so focused on the shitty alignments. Like how can you fuck up only some of the 'S’s? I get that the ports are a result of the outline of the parts soldered to the board. And getting the HDMI vertically centered, or having the single USB port not turned 180°, would require both effort and a bit pricier BOM … But! The engraving? It’s the one thing that’s not relying on external factors.

That’s the reason I don’t drive a VW ID3. I wanted one, I really really wanted one. But during my test drive, I got a 10s timeout from the display, for apparently tapping too fast while trying to adjust the AC, WTF? And don’t get me started on the stupid mood lighting.
Too bad, it was in my price range, rear wheel drive, 236hp and a decent range. And there’s soo many of them on the roads in my country that spare parts wouldn’t be an issue.
Luckily it looks like some car manufactures have decided to ditch the ginormous look-at-me-I’m-just-like-a-tesla touch-screens. Kia, hyundai and VW at least according to slashgear.com/…/major-automakers-removing-touch-s…
- Comment on AWS crash causes $2,000 Smart Beds to overheat and get stuck upright 2 months ago:
Different appliance, same experience.
First off, the “smart” part is just another thing that can break.
Secondly, why is it cheaper than the older/dumb device? Don’t try to tell me it’s because the manufacturer had to develop new electronics, with pricier components. Isn’t it far more plausible, that it’s because my personal data is part of the price, without my knowledge?
Thirdly, what happens when the manufacturer gets liquidated? and the new owner decides that I need a subscription to use the device effectively either bricking it or raping me. Like we saw with Futurehome …openhomefoundation.org/you-dont-own-it-if-they-c…
Or what about when the manufacturer decides that they don’t like you and decides to snuff your account? Like amazon did when a driver foxbusiness.com/…/amazon-customer-claims-company-… sure, if you’re abusive towards staff, then by all means act on it. But lockjng people out of their smart home, without giving them a chance to respond to the accusations first?

We’re all different, I do realize that, but I don’t do just-in-time delivery for my household products. I’ll buy a couple of bottles of rinse aid, and once the last bottle is empty I put it on the grocery list.
I don’t need to know that the dishwasher has run out, I’ll deal with it when I see it.
And do not tell me where to jump or not 😀 I’ll jump in front/on top/behind of ridiculous conclusions if I please /s
- Comment on AWS crash causes $2,000 Smart Beds to overheat and get stuck upright 2 months ago:
Because, and this may surprise you, some (most?) people don’t think about how their stuff works. They just see it has an app and goes “neat!”.
I don’t know why my dishwasher should be online. But I’ve been with people who’s smart watches twinkled to alert them that their dishwasher, located 30min away, was out of rinse aid. I no scenario is that relevant. Rant warning There’s a God damn light on the front of the unit, that tells you the same damn thing, and you can’t do anything about without being at the unit. What are you going to do? Drop whatever you’re doing at work and take an hour lunch break early to drive home and deal with it? Didn’t think so.
BUT the person had seen the dishwasher and thought it was neat, modern, and needed a new dishwasher. And that’s whywe end up with a lot of “smart” devices, which are just “ordinary devices with an cloud based remote control”

- Comment on Tragic Titan submersible’s $62 SanDisk memory card found undamaged at wreckage site 2 months ago:
And even if you sampled at 10 sps, and did 50 sensors at 10b, you would still only be looking 5000bps or 5.8x10^-7^ GBps, meaning that it would take roughly 26 years to fill up a 512GB SD card.
While I don’t know for how long the sub had been submerged, I doubt it was close to a quarter of a century. If that was the case, I believe that we would have been talking about that as well. Even if it was 500 sensors, at 100sps at 12b we’d be looking at 79days.
IMHO there’s only a few things a 512GB SD card would be used for. And I hope it was music, because I don’t think we should watch the final moments of these people’s lives.
