I'm going the custom length outdoor light route for the first time and ordered a bunch of stuff from christmasdecorators.com and realize now that I need a few more plugs and some zip cord. I'm trying to get this done on Saturday so I can't just order online (no one sells these via Amazon Prime). I have to head down from Berkeley to Sunnyvale for work tomorrow so almost the whole Bay Area is in play.
Is replacing the fan on a convection oven a DIY project? The fan on my Viking electric oven made a bunch of noise then started smoking, so I'm guessing that's what failed. Is replacing it a doable project for someone with moderate electrical skills? And is it something I should try to tackle this weekend, before Thanksgiving? (I can cook w/o convection in the meanwhile.) [more inside]
I would like to run some portion of one of those cuttable LED strips off of a battery or batteries. Is this possible? How do I calculate how to do that given that these strips use 12v DC converters to run when plugged in?
I'm waiting on a call back from the doctor, but am just trying to understand the magnitude of this potential shock. Minor or major? [more inside]
I need to find the best and most diplomatic way of getting my landlord to fix some of the electrical work in my apartment, and could use some help regarding finer points about the National and Massachusetts Electric Codes, and/or Tenant's Rights. [more inside]

The light switch inside our bedroom corresponds to a wall sconce over our bed. My wife hates the lighting from it and would prefer lamps. What's the best way to get the switch to control plugged-in lamps? [more inside]
I've decided I want to make better, more purposeful use of my downtime to get myself out of a rut. I'd like to take some ongoing (not one-off) classes in something that is engaging and practically useful. I'm feeling drawn to mechanical-type things, like learning how to do basic electrician stuff or auto repair. Any ideas? North Seattle would be ideal but I can travel.
We have a spot on our wall where a doorbell used to be mounted. We no longer have the doorbell, but the electrical box is still there and the wires are still in place. I currently have it covered with a painted blank plate but I'm wondering if there are any other creative ways we could cover this and make it less conspicuous. [more inside]
I'd like an easy way to keep track of what I need to do on a seasonal, annual, and 5-year basis to ensure my home is functioning well. I'm looking for a way to keep track of when the last time various systems were serviced and/or what I need to do in the next month. How do you keep track of your maintenance cycles and tasks?

We moved into our little one-story house in Toronto a few months ago and one thing that came up on the home inspection was that our pot lights are not covered by vapour boots. Since then, I spoke to an insulation guy about upgrading the insulation in the attic and he suggested that instead of putting in vapour boots, switching all the pot lights to LED would be more affordable/easier; he suggested replacing the halogens with LEDs as they burnt out. Well, one bulb has burned out. I'm confused about the replacement choices. [more inside]
Bought an LED light fixture. Only now noticed the instructions say "must be mounted on ceiling". Can I mount it on a wall anyway? [more inside]
I've just moved into a new (to me) house. (The house itself is old and quite funky.) I brought with me my extant Macbook Pro (most-recent vintage). I'm finding that when my computer is fully charged and the charging cable is plugged in (green light), the house lights flicker. [more inside]
I bought a Waterpik about three years ago but never took it out of the box until tonight. There is a recessed port with two brass-colored prongs at the base of the device, for charging. Upon inspection, I discovered that the prongs were covered in weird gunk. [more inside]
I'm moving into a house that is almost entirely 2 prongs. Sure there are 3->2 prong adapters. But is there a safer way to use these outlets without tearing up the walls? Are there any relevant safety gadgets out there?
I need to temporarily (20 minutes to a week) attach a test lead to a gold pad on one side of a printed circuit board. The gold pad is about 10 mm in diameter and the center is about 12 mm from the edge of the board. There are surface mount components on the other side of the board, so an alligator clip would be sub-optimal. The input signal is a few millivolts. [more inside]
I have recently bought a flat (yay!). I had an electrician in today to look at some broken appliances (the hob, fridge and bathroom fan), and while checking things out he noticed that the voltage of the power in the house was unusually high (248-250V), possibly because I'm close to the transformer, and he confirmed that this could shorten the life of electrical devices. He mentioned that you can now buy a gadget to add to your electrics to step down the voltage to a more normal level, like ~220V. Is it true that a high-ish voltage can cause problems, and does anyone have any experience of the voltage-fixer he mentioned? I'm in the UK.
So I managed to get myself a job in a busy factory as an electrically biased maintanance man and need resources to help me become more up to scratch with what im dealing with. [more inside]
Why would using an American electrical device on European voltage cause it to short out circuits at home when I plug it in again after coming home to the US? [more inside]

My car (2012 BMW 328i xDrive Wagon E91 LCI) has two quirks: 1) battery warning after turning off the car, even after extended drives (never BEFORE starting the car) 2) brake wear warning after car has been parked in the cold for several hours (disappears after warming car up) [more inside]

The rubbery casing on my MacBook's charger just split after 6 months of use. I bought this one after the same thing happened to my last one. It's not splitting in the high strain zone near the body of the adapter, but part way down the cord. What's the best way to prevent the cord from splitting further? I've tried electrical tape previously, but it doesn't hold up well and leaves a lot of goopy adhesive behind. Thanks!
Does anyone know anything about electricity? Here's the situation. About a week ago, the overhead lights in my dining room and living room went out simultaneously -- we saw it happen. There is another light (kitchen overhead) on that circuit that is now out as well. I think it was turned off at the time, so we only noticed it later, but I am guessing it went out at the same time as the others. [more inside]

My wife removed the stereo from our 2006 Renault Scenic to extract a coin that had been stuffed in the CD slot by one of our lovely children. This wasn't the first time she'd done this, and there haven't been any problems in the past. However, upon returning the unit this time, the dash controls for the stereo were found not to work, only those on the steering column. She removed the unit again, checked the fuses, replaced the unit - and now the bloody air conditioner is dead. [more inside]
I replaced a ceiling light in a 1950's-wired apartment. There are insulated black and neutral wires, but no ground connection (fixture has ground wire but just connected it to mounting bar). If wired backwards, what happens when I flip the switch? When I touch the fixture while power and/or switch are on? [more inside]
One of the power windows in my car has stopped rolling up. The windows are controlled by a dual switch in the center console. The driver's side works, and the passenger "down" works, but the passenger "up" switch does not. I tried replacing it with a new switch I ordered online, and was able to get the window 90% up, but then that new switch abruptly stopped working. Is this likely to be a case of a bad part, or is there something wrong with my electrical system? More details below. [more inside]
So, my apartment complex installed a new exhaust fan in our unit. This is great! it's powerful and will be an excellent addition to the kitchen! However, they inconveniently placed the switch for the fan about 2 inches too low for comfort (pictures inside). When the oven is pushed in the switch gets covered up. Is this the sort of thing I can move myself? Or is this the sort of thing I should pay an electrician for? How much? (And for the sake of argument, let's assume my apartment complex is fine with me doing this.) [more inside]
I'm toying with the idea of DIYing a version of this ceiling lamp. Can anyone tell me the technical name for the pivoting/rotating/swiveling T joints, as Googling combinations of that phrase is not giving me similar connectors? [more inside]
We have this furnace. In the summer it would be nice if we could run only the fan (We don't have central air), but according to the manual, Fan Only Mode requires the R and G thermostat contacts be wired. As you can see, only the RC/RH and W contacts are wired. Would simply swapping the orange wire from RC/RH to RH/G create the circuit needed for sweet, sweet fan action, or will it be necessary to run a new wire from G to the control board in the furnace, therefore requiring professional help? [more inside]
While snooping around my basement today I found a strange little box/connector of some sort that I have no idea what it is. It looks really old (the house is ~90 years old) and isn't currently connected to anything. It seems to correspond to the incoming phone line from the outside box, but I could be mistaken. Can anyone tell me what exactly this is? [img inside] [more inside]
YANM medical billing professional, but I need help in getting my very expensive, recently-out-of-warranty electric wheelchair fixed. I live in NY, have (crappy) private insurance ( Oxford Liberty) through my mother's job and Medicaid due to a cerebral palsy diagnosis. My chair ( an Invacare model) was provided through my previous insurance and OL isn't accepted by the contractor that provided it. They take Medicaid, but refuse to put in a claim and keep passing the buck. I can't leave my house. What do I do? [more inside]
I have a Frigidaire dehumidifier with a short (when I plug it in, it trips the fuse on any house circuit I try). Should I try to fix it, or is it likely to be unobvious? I'm not particularly handy, but I don't mind taking something apart. Is it safer/better to simply dispose of it? If so, is it recyclable?
When I'm sitting in the room with the breaker box to my house, I hear a series of short buzzes, like "bzzzt." The noise seems to be coming from the breaker box, and I notice that a faceplate to one of the switches is missing (breakers were last switched off a month or two ago, when new heat pump was installed.). Here is (or should be) the image (if not, there's just copper surface where the breaker faceplate should be):
I'm interested in adapting this tutorial and this tutorial into a dress design. Basically, I want to keep the accelerometer as part of the design, but have lower profile lights and reduce the number of lines to two or three, somehow... I could solder two extra beads (right?) on but it would look better with just two or three beads/lines. What can I do? The accelerometer isn't super-required since I can just program sparkles, so losing that isn't completely off the table. [more inside]

One of our circuit breakers tripped, and it won't return to its "on" position. I push it toward "on," but it doesn't stay, just returns to a middle position between on and off. It serves only a single hallway in the home, and nothing is plugged in there. Does the breaker need to be replaced? Should I call an electrician?
I don't really understand the utility industry very much but I've noticed some electric companies are very responsive to getting lines up from damage and have crews out at 2 a.m., and others don't even start work until the next day. What motivates them? Is it primarily loss of earnings from all the meters not running? Are there regulatory performance expectations? Or is there some sort of precedent in litigation that would put them at fault for underperforming? [more inside]
