Do-It-Yourself, Repairs and Fixes

has anyone here ever experimented with an "electromagnetic" pump? If the pumped liquid is conductive and the piping is enclosed in a coil (think solenoid), and a current is passed across the fluid near the coil, then the magnetic field made by the coil should attract the fluid passing the transverse current (causing it to flow). As fluid flows toward the coil, new fluid starts passing current and so on.

Electromagnetic pumps are used in metal processing for continuous casting, but those are fancy and expensive devices. Could I pump seawater by wrapping a coil around a garden hose and pop-riveting a couple of electrical contacts into the hose on opposite sides next to the coil? I think regular "fresh" water would not be sufficiently conductive, but whatdoIknow? My longer term plan is to try pumping molten salt, but I want to learn on cooler stuff first.

I'm all ears!

I've been having a problem with my Honda GCV 160 recently.

Neighbor was using it and accidentally ran over a bag, force stopping the motor. Cleaned the blades out and tried to run again, just spluttered but didn't turn over. It sat like that for a while, no luck on turning over.

I took the carb apart and cleaned all of the components thoroughly with carb cleaner, reassembled and it actually ran nicely for about ten minutes. It then slowly revved down and stalled, and now it won't run again.

Is it an air intake issue? Bad gas? I put a new air filter in, too.

Who else's got a wet trunk?

I think my sunroof drains might have been clogged. Any suggestions as to the best way to dry it out?

I've tried google/youtube and can't seem to find any decent tutorials/instructions for my particular situation, so I'm hoping someone can help get me started on this repair job. I don't necessarily need a full breakdown or step-by-step instructional, but some help with the terminology, techniques and materials I would need to learn and use to accomplish this project would be greatly appreciated!

The project is the interior face of a very old chimney that protrudes through the floor of a 3rd floor bedroom and up through the ceiling. I believe the term for the stuff on there now is called "render" as it is like a stucco/plaster smooth-ish finish nearly an inch thick overtop of the original brick. This finish coat is in bad condition and falling off the brick near the ceiling. The rest of it is still holding but there are some cracks and I'd rather not test its integrity until I know what my plan is. The chimney is lined already and is used exclusively as a vent for a propane boiler in the basement. There are no fireplaces or anything in use anymore. This is in an early 19th century farmhouse in the US, so the brick is very old but still solid (no loose bricks or anything like that). Bits of the mortar are loose and will likely need to be re-pointed if I take any of this stuff down but I'm happy to do that.

Ultimately I just want it to look nice, not be falling apart and creating dust, and probably most importantly: not leak any rogue gas fumes into our soon-to-be guestroom. I think because the chimney has a liner in it already, the gas isn't an issue but I didn't put it in so I really can't be certain of what kind of job was done. I'll put a CO2 monitor in the room regardless, but would rather avoid that problem altogether. I'm fine with either reinforcing the render to give it a few more years or cleaning it all off and resurfacing the brick somehow. Any suggestions?

I always end up in decision paralysis because I think of way too many possibilities. Is there a way I can avoid brackets? If I am able to drill into studs should I just use normal wood screws? I'll be using it as a tea/spice shelf.

Anyone else have trouble with these GE dishwashing machines?

Mine cleans dishes well enough, but the gaskets leak easier than any other dishwasher I've ever had. I replaced the gaskets a few months ago, but if a little bit of debris builds up then it's leaking again. Also, the racks are badly corroded, but the machine is only maybe five years old. Anyway, it's just kind of funny that my aunt is coming over tomorrow and the last time she was here she noticed the dishwasher was leaking.

I have a Rexing Dashcam that I've used for a couple years, and lately it's been behaving badly. It works perfectly fine while on, but when it's time for it to shut down, it often will shut off early, then reboot over and over until its internal battery is totally dead.

Everyone on the net says it's a bad card. Nope. It does mess up the card's partition by quitting in an uncontrolled fashion and by rebooting over and over, but I took the thing apart and the real problem was that the little internal battery is swollen and almost dead.

All the battery does is provide the camera with up to 30 seconds to save the currently captured video and perform a controlled shutdown, and as such, it's quite small. The battery in my V1LG was a 602040 3.7V 450mAh lipo. It was pretty badly swollen (they are supposed to be relatively flat). I've ordered a cheap replacement for $7, which is a lot cheaper than a new dashcam.

Anyway, if your dashcam is behaving oddly at power-down, and you've tried different cards with no success, it may be your battery.

The Gerber armbar has got 2 holes for an awful plastic clip and I thought "easy fix" - it wasn't. Had to order screws M2x4mm & M2 nuts and had to drill very exact, worked out in the end, I present: Frankentool® PS: Locktite's your friend.

Inherited a little flux core welder a while ago if you know of any good books or videos please share. Had a stick welder years ago but never got a feel for working on thin stuff, I'm guessing this will be the opposite problem.

I het the general theory looking for like practice drills and how to read a weld to know what wrong

This toothbrush still holds enough charge for over a month of use after 4 years so I guess I will charge it like this from now on.

$15 for keyboard tilt clips is outrageous. Luckily I had some cheap steel wire laying around from Christmas.

I have a solar panel from a cheap Walmart device I tore down. Hooking it to a Multi-Meter shows it's about 2.25V (probably supposed to be 2.5V but runs a little low?).

What's something useful I can do with it?

you will always have that favorite piece of clothing or like a backpack that needs repair etc.

It's not even hard and looks better than before in almost all cases imo, even if you're not skilled.

Meeting people where they are with technology is so important, and I love that this lets the grandchildren message from their phones as is presumably convenient for them.

Realizing that this would be a clutch heirloom to have cast of my mother and grandmother.... think they'd go for it?

Or make one of myself and specify in my will that to inherit, any heirs have to make pan de muerto in it and eat it...

I have.... let's say.... no hardware experience.
