A last ditch effort would be to ask in the electronics megathread here in DIY. They might be able to come up with something. Also, I found a few of those FBELE parts on alibaba.com. Even if you did have to order the minimum of a thousand parts, it would still be cheaper than the $90 that Teledoorbell wanted. edit: here you go!

With Tesla selling home Li-Ion batteries, is the idea you charge at night with cheap electricity, and power your house in the day with the battery, thus lowering your cost, or does that not make sense? Is sposed to couple with solar so you have 24 hr power?

It's like the unicorn of speakers, I'm having no luck so far. Looks awfully similar to a headphone driver. Maybe ask around at head-fi or one of those headphone enthusiast sites.

At the local art center an air compressor is used for spraying glaze on pots. The sprayer works at 45psi and there is no bladder on the compressor so you have to spray in short bursts. Because the psi is quite low, and the volume is low, is there a cheap bladder to build? Can I just build a bladder out of 4" pvc with some check valves?

I'm sure you can find a free junk pancake compressor around easily and simply use the (properly built for the purpose) tank from that.

They're cheap & plentiful. Alternately, old fire extinguishers, old grill propane tanks (that have been disassembled and filled/emptied completely with water to flush propane), mounted car tires, and really anything else can be used to hold 45 PSI.

Phanatic posted:It *sort* of makes sense. That's an excellent analysis, except I think they've underestimated the installed cost a bit; 30%-40% is probably closer (for example, SolarCity is advertising $5000 installed), so more like 17 cents per kWh. It doesn't make sense (yet) for the average American, but it is impressively close. Solar installs without net-metering agreements are still priced well beyond (battery + panels should be in the 35-40 cents per kWh LCOE) what makes sense in almost any part of the U.S. Hawaii Electric is probably making GBS threads itself right now; for the rest of the country this is just a POCO wakeup call - grid defection is very close to being viable, and if they don't rethink how they run as a business right now they'll be dead within 30 years. POCO's that listen to that wakeup call should be able to offer incentives in excess of that $0.17/kWh, at least in some areas. With a 3.3 kW peak draw, $1500/kW is below the installed cost of almost any grid-scale storage (even pumped hydro), and distributed storage also relieves load on distribution systems. So far, this has only been leveraged in small scale pilots, but the mainstream draw of Tesla's batteries could make a big difference there.

Last year my AC condenser stopped working. I changed the capacitor myself, and had a professional come out and change the fan motor. At the time he did not change the fan, and I recall him mentioning that it was shaking a bit, but he did something and brought it back and said that would fix it for a while. I guess a while has come, because my condenser isn't working again. The motor is fine, obviously, but the fan itself was cock-eyed, with one side sticking up so that it would hit the top grill and the other side sitting down on some of the wires, effectively lodging it. I did not think to get a picture of that. I took the top off and here's how the fan looks: and here's how it looks when I manually hold the fan up I'm assuming I need a new fan. Should I attempt it myself--it seems easy enough, but I don't want to gently caress up any of the wiring the guys did last year. Also, any time I look up "how to change fan" I get instructions on how to change the motor.

It's not too hard, the only tricky part will be to make sure the new blades have the same angle-- the motor is expecting a certain amount of load and airflow to operate efficiently and cool itself. Also if the condenser has a cowl that the fan sits in, the new one will need to be at the same height as close as you can get it otherwise you might induce turbulence that could reduce airflow and or create undesirable vibrations. If you have a grainger in town they have a pretty wide selection http://www.grainger.com/category/condenser-fan-blades/fan-blades-and-propellers/hvac-and-refrigeration/ecatalog/N-jra Also if you have trouble getting the old center of that fan off, PB blaster works wonders.

I've got this water hammer that seems to be coming from the laundry room. I'm assuming cold water too, as there's a brand new expansion tank installed for the hot water. The hammer happens pretty much whenever water is used anywhere in the house, intermittent thuds separated by at least a few seconds. Are those little water hammer arrester things made for laundry likely to help, or what should I be looking at here?

If it's happening on every faucet in the house, I would be suspect of the water pressure. Fixtures usually like 40-60psi.

Does anyone know what this light socket that is over my bathroom mirror is called? It has no serial/model number or anything on it. It's 31.5cm long. The (long lost) tube that was in it had connectors on the side of the tube (like, at 90 degrees to the length of the tube) that fit in the large sockets at either end of the mount. Feel free to laugh at me if this is a super common light fitting where you are. I'm in Australia and this is the only one I've ever seen.

Wow, that's an odd one. That looks like it takes some type of double ended halogen bulb. Their wattage is linked to their length though. A ~300mm one would be around 1500W, which would be absolutely blinding over a bathroom mirror, so maybe not a halogen. I don't suppose you have any other of those fixtures in your place do you? What about your neighbors? You could maybe get a better look at an existing bulb, maybe even take it down to the store and match it up. edit: After looking at it again, I get the feeling that it's missing pieces. You might definitely want to check out a neighbor's fixture just to see if anything is missing. kid sinister fucked around with this message at 19:49 on May 7, 2015 |

So a couple years ago I had a basement man-cave room remodeled into an office. The old floor was commercial tile over cutback glue straight to the slab. Some asbestos remediation was needed . For cost, I decided to go with VCT (vinyl composition tile, i.e. grocery store tile) to replace it, and had read *somewhere* that the old cutback glue should be removed with mineral spirits before putting down modern clearset glue. The flooring subcontractor disagreed, said that the clearset would go over the cutback no problem, and since the other subs had been pretty decent, I trusted him. Here are some glamor shots of what is happening at the tile joints now: At first it was a couple of spots here and there, but now whenever it stays wet outside for a couple of days and the slab sucks up more moisture than normal, 1 to 3-inch puddles of clearset+cutback mixture will erupt from the floor sometimes when I step on a tile that doesn't see much traffic, and the little quarter-inch spots will just spontaneously pop up wherever they feel like. I'm planning on talking to the contractor about this, but I was wondering what the goon prognosis was for my floor. Is this something that can be fixed with the tiles in place, are we going to have to redo the whole floor, or will this eventually stop happening and I'm just being a big sissy? Also, I'm a bit concerned that the cutback glue might be impregnated with asbestos. It doesn't seem friable, even where the spots have dried out, but is a thing that people really did? The house was built in 1968 if that helps, though the old tile could have been installed pretty much any time between then and, say, 1980.

The Mrs is happy and I didn't have to wire anything, so I'm calling this a win. The US is like that too now. Stores can't buy incandescent bulbs to sell them here anymore, but stores can sell their existing stock. Stores knew this ban was coming, so they massively stocked up. I could see why they wouldn't bother stocking specialty bulbs like that though. I could see this as a problem in the future for certain fixtures even with regular sockets where you just can't cram the fat base of a CFL or LED bulb in there.
