I feel like the only way to actually automatically clean a shower, like to the point where you would never have to go back and clean it for real because the automated system is weak and misses areas, would be to like fill the entire bathroom with high-pressure steam.

I seem to remember the tech bubel thread theorizing that just adding steam jets to the Dymaxion House bathroom would do the trick:

Buckminster Fuller's Dymaxion House posted:

The bathroom consisted of two connected stamped copper bubbles, built as four nesting pieces. The bottom piece is fully plated in tin/antimony alloy and the top half is painted. Each bubble had a drain. No area had a radius of less than four inches (10 cm), to aid cleaning. The commode, shower, bathtub and sink were molded into the structural shell in one piece. One bubble contained a step-up ergonomic bathtub and shower, high enough to wash children without stooping, but just two steps (16 inches / 40 cm) up. The oval tub had the controls mounted on the inside left of the entrance to the oval tub. The other bubble was the bathroom proper with commode and sink. The ventilation for the bathroom was a large silent fan under the main sink, which kept odors away from people's noses.

So the scrubbing bubbles just sprayed soap everywhere?

That doesn't clean poo poo. Please take a brush to your showers now and then goons, like maybe once a month? 4 times a year, I can compromise?

Yeah it doesn't have to work, just look like it does the same thing as the other one.

Where I work we are getting hosed on voltage regulators. Not particularly fancy ones either.

I am getting completely hosed, professionally, by the shortages.


Just bought up the world's supply of a critical part directly from the MFG, in the hopes that it will tide me over until October.

I bought out the world's supply of a particular type of MOSFET a couple of months ago. Mostly because they went EOL and all of our old equipment depends on them so we needed the spares. On the upside it made for a pretty easy pitch for some money to update those systems.

My parents had one at one time and I think the solution had some very diluted bleach or something in it that would kill anything that might grow. You still have to clean the shower to get rid of soap scum and such, it's just this way it gets sprayed down every time you use it so you don't get mold on the grout. That was the idea, anyway.

Lol it's like the after shower spray except if you forget to close the shower curtain it makes a huge mess. Also it takes batteries.

#1 shower cleaning tip from me: switch to body wash from bar soap. Much less horrible soap scum to gently caress with

I don't think we ever had a problem of not closing the shower curtain, the real reason it didn't really work iirc is that it kinda piddles out the liquid so unless your shower is only 3 feet by 3 feet it's just gonna spray the area immediately around the shower head and nothing else.

Yep, this thing would break after about a year and sold for $25. They now sell for $200 on Amazon and are definitely not worth it.

Yea its this. An ex had one and it worked well for this limited use case, still needed to scrub a couple times a year. Currently my wife and I have some spending money but 0 extra time so we're looking to clean up the house in as automated way as possible.

Dominoes posted:

Agree on using existing nozzles etc. And there are many ways to reach this goal, including and beyond the Scrubbing bubbles design. Fix nozzle, pressure-powered moving nozzle as you suggest, electric nozzle, water source siphoning from line pressure (like lawn sprinklers etc), own water tank, multiple devices around the shower working independently / together / single device etc etc. Mesh-networked van-der-waal-hugging squeegee bots.

Yep. I think the goal would be neat and a thing me / other people would use.

LMK if you wanna work together on it at some point in the future, I'd love to work with you on a thing. I'd be willing to form a company you majority own and what not if we get a prototype together.

If we did a sealed battery and could basically just pot a connector, I think we could solve the intrusion and battery corrosion issue. And it might actually be cheaper and easier to assemble.

I'll hit you up once I've got more time avail / am ready for a new proj.

e: What are you imagining the battery powering? Run-time and schedule timers, maybe nozzle adjustments, button-to-wake-from a standby mode etc? If it doesn't power any motors etc, could probably use a coin cell, which would make your waterproof housing simpler.

Anyone know how to crimp one of these right-angle spade terminal things?



Do you even crimp them? I guess I could solder a bare one, but what about an insulated one like this?



e: Nevermind I found the specific tool to do it with like a minute after I posted

Trying to repair an oven. I think it's the relays. Can I buy replacements? I am pretty sure the same part is no longer made, and I don't know how to tell if something will work as an equivalent. Trying to search I find things that look the same but say DC instead of AC which seems like I'm no where close.

Here's a photo



The contact is scorched. It looks like this on both the bake and broil relays.

Symptoms: When you turn on the oven and set it to bake, it pre-heats normally, with the element cycling on and off during pre-heating. Then when it reaches the set temp, the element stays on and will not turn off until you turn off the oven.

Model numbers etc. on the two parts

The relay seems to be this one:
https://smile.amazon.com/CONNECTIVITY-POTTER-BRUMFIELD-T90N5D12-12-pieces/dp/B00LQPWBZU
with this datasheet which says it can switch 240V AC at 30A, the 12V is control power, I guess.
http://www.farnell.com/datasheets/1828107.pdf

Searching the second number shows this guy used a newer Omron relay and had it work:

I'd double check other stuff too. You said it still cycles while pre-heating, which kinda hints that the relay might be fine (well, clearly not fine, definitely still replace that mess, but functioning) since when relays fail they usually either weld together and never turn off, or get so corroded that they never turn on (or turn on erratically). The whole "turns on and off normally during preheat, but then doesn't turn off when up to temp" almost sounds like a thermostat problem or something.

Hmm, dang. Well, it has a digital read out of the temperature which appears functional (again, during pre-heating but not after), so I'm pretty sure it's on the board not a sensor.
