Don’t lick, that’s dangerous, but nobody said “don’t eat 60/40 solder”. So go for it. Just remember to put a few sheets of paper in the bowl before taking a dump, otherwise you might break it.

I whole heartedly agree with you on the virtue of simplicity in design, and this heater is a bit over the top for its basic function. But we wanted something that

1. Could do 400V
2. We could control remotely
3. Was available for sale in Denmark in case if an RMA

and at the time that narrowed it down to either the Clea or neo series from adax, and I believe one other product line from a second manufacturer. The remote control part was really hard to find in 400V.

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.

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.

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.

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.

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.

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.

Yes, it certainly bears semblance to my first 9 months in solitary confinement, before the hag dragged me out from her wretched womb. Curse you vile woman!

Well it’s what you get when you decide to instill democratic values in every school child for decades. Perhaps we should make note of that?

It’s finally coming to England.

I want to believe, I really do. But I fear that the crypto apps people have grown dependent on will make it harder than the desktop battle. And IDK but I seem to recall every year since at least 2001 being proclaimed to be the year of the Linux desktop.

I rely on my banking apps (plural), governmental email app, government authentificator app and the governmental LMS app for public schools to make my everyday function. And the last time I tried just a custom ROM, those apps refused to run.

An astroid the mass of the meat half of a giraffe and the volume of 5kg of somewhat dry duck feathers…

I’m beginning to think that it would more relatable if it was just stated in kg or m^3 instead

And is it half the volume, mass or a dimension? Because I’ve never tried neither blending or carrying a giraffe before (I never got invited to those parties in uni) so I have no grasp on volume or mass.

Is the terminal emulator set up correctly in regards to baudrate and stopbits? I would try playing around with these settings.

I haven’t used Dell gear before, but you are sure that it’s not some proprietary protocol that’s running over serial? As in it requires some special software instead of a console?

I’m not sure what you mean by the signals being dirty. If it’s the slope after the initial fast rise you mean, I guess it could be remedied with an opamp, a push-pull pair, an optocoupler, or some other switching circuit with a suitable power capacity. But as long as it gets above the hysteresis threshold for long enough it should be fine. Whether that’s happens you should be able to tell from the scope (which I can’t see while writing in my client)

Indeed, feeling the need to check, I can tell you that we’re not in the onion anymore…

And here I thought I had it all figured out. But it does make sense. Doing it with an analog signal introduces noise and measuring pulse widths is going to be simpler.

Ok, but what’s the chance of being hatched on each continent? I believe that it’s a statistical insignificant amount penguins being born anyway

Except that wasn’t a serial port, it was midi, and the reason it was on the sound card was because the input was analog.

Your joystick was just two fancy potentiometers, and your soundcard decoded the voltage on the middle legs into a position.

Soundcards handled joysticks because they had the fastest ADCs.
