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]
My husband likes to take electronics apart and put them back together (cameras, smart phones etc.). Right now his setup is ridiculous: he works (mostly) over a big tupperware container to catch the screws that fall into it, unless they fall on the floor, and he holds the flashlight on his iPhone with one hand while trying to wrestle tiny screws into place with the other hand. There has to be a better way; this looks painful. what can i buy him to improve his setup (lights, magnifiers, other things i haven't thought about)? What do you use in your efficient and effective home repair shops?
So, my 15mo old daughter poured a cup of coffee in my 2011 Mac Book Pro, and now the keyboard and none of the ports work. I am trying to figure out what to replace it with, if anything (at the moment). [more inside]
Why does the signal keep dropping on my Wii? [more inside]
These are various .avi files from old which my player a Panasonic Blu-Ray DMP-BDT230 supposedly supports. It will 50% of the time but only show the picture and then a high pitch dog-level sound comes through speakers. It is connected via HDMI to TV with TV's audio output RCA to early 2000s receiver.

My current house room setup doesn't make sense, and I'd like to move the media room to a different location. However, the only available wall for for TV/Xbox/Etc, is the wall that divides the kitchen and the living room; so the TV would be hung on the same wall as the microwave and stove, but on the other side, in a different room. (If that makes sense.) Is interference still a thing, or is most equipment shielded enough that this idea isn't a problem?
Is the control panel on my gas oven really completely fried after switching the breaker on and off? How can I prevent this in the future? [more inside]
My fiance sold and shipped some very expensive, heavy, one-of-a-kind electronics to an online friend overseas. They were damaged during international shipping. The purchase price was over a thousand dollars and the items are literally irreplaceable. Who is legally liable here? What are the ethics? We *cannot* afford to reimburse this expense. [more inside]
I have a refurb monitor that's starting to go bad: the screen will fill with vertical color lines that don't change once they appear. Cycling the power almost always fixes it, but it's starting to happen more often. There are three boards inside - which is the likely culprit? [more inside]
I'm trying to set up several micro USB charging stations in my house and car, and I'm realizing that I retain very little from 9th-grade Intro To Electronics. Set me straight on how current works? [more inside]
So - I need to epoxy some wire back into a tiny plug. The old one holding it was whitish. Can I use regular epoxy or do I need some kind that it especially made for electronics? Thanks

My mother-in-law's TV is out of HDMI ports. I need a switch and a cable. I can't order online-- I need to be here to set up, and leave early Monday. Best Buy/Radio Shack are last resorts. [more inside]
Recently I found a good deal on a direct drive DJ turntable which was manufactured for the japanese market. I know japanese consumer electronics run on 100V while US runs on 120V. I have heard conflicting things on whether this would be an issue. It seems like the turntable would likely run but I have heard some reports that this difference in voltage might eventually damage it. Is a power adaptor a permanent solution to this problem? Is a power adaptor even necessary?
A few months ago I moved into a new apartment, and decided to get one of these industrial shelving units - something like this to use as a desk/bookshelf/musical gear shelf. Everything works great, except when I plug my macbook into its charger and start typing. If my hands are on the aluminum body of the macbook and my wrists brush up against the metal frame of the shelving unit, I get a sharp shock, nothing too bad, but painful and annoying. [more inside]

I am thinking of getting a friend's old Realistic receiver (Realistic STA-65C, I think). I am not of the nature that I need an exact model replacement of the treble knob and am curious if there is a place online or a store like Home Depot or Radio Shack that might sell knobs that could fit or made to fit. I know eventually I may find one on ebay but don't need it to be a perfect match nor spend too much. [more inside]

I was given a tablet demo unit from my workplace because we no longer sell this model. It's functional and great, but still has the old security base attached. It's a circular nub about 1" thick that fits into the cradle of the demo pedestal, and has wires coming off both ends of the nub. I can cut off the wires, but the nub is superglued onto the back of the device. What's the best way to remove it? Photos within. [more inside]

I have this USB DAC/headphone amp (which is great). I just started using the RCA outputs for a pair of powered monitors (also great). The problem is that the DAC switches between the outputs based on whether the headphones are plugged in. This makes sense, but it's annoying. I want to hack it and switch between them manually. Electronics whizzes, check my reasoning. [more inside]
I inherited this rice cooker but cannot figure out what buttons to use to make regular short grain Asian rice. I thought it was the large one on the right but the rice is gross and uncooked yet soggy. Can you help? I looooove rice and need to remedy fast. Thanks for your help. Can you tell me what all of these buttons mean? I can't find a mode number so I can't look up the operating instructions online.

I have an idea for a half-and-half forearm tattoo (like this) where one half will be filled in such a way to represent computation, computers, electronics, artificial intelligence, something like that.

I need basically this. I'd rather order it from closer to home. My searches for this type of cable in the US haven't turned up anything, and I don't know enough about electronics to figure out what other names it might go by. I think it's a common type of cable so there must be something I'm missing. Thanks!

Is it feasible to take apart, modify, and put back together again a hair dryer so that it works in reverse, that is, become a small vacuum? I assume I would have to make the blower work backwards to become a sucker, and I would have to direct debris into a little sack and away from the blower and power source. If I were going to do it, what would I do? How much work would it be? How ugly would it be, assuming rudimentary skills and a home workshop? If it's impossible-- why?

It's generally advised to leave as much behind as possible when moving abroad, but my wife's employer is paying to have a decent amount of our household stuff transported from the US to the UK. And why would we want to waste money buying duplicate items if it isn't necessary and we probably won't be staying more than a couple years? So I'm trying to figure out which of our electronics and appliances might be made to work overseas. I am aware of the voltage difference and the line/mains frequency difference between the US and the UK and I'm considering buying one or two good-quality step-down voltage converters for things that aren't universal voltage compatible. But I have some questions that my Google research has not cleared up. [more inside]
We have a ton of devices with different chargers and I am looking for a clean charging station that will hide the cord clutter but still allow us to charge multiple devices (with varying connectors) at once. Any recommendations? [more inside]
I'd like a thin and light 1080p laptop. It does not need to be powerful, but it does need to be cheap. I'd like to spend about $300, but it must be under $500. The perfect machine would be something like a chromebook, but with a higher res screen than the ones I'm aware of. The resolution requirement trumps the thin and light requirements. [more inside]
I am playing with an animatronic toy I got from a thrift shop. Before I started trying to hack it, there was a rocker switch that when pressed in one direction, made the head turn left, and when pressed in the other direction, made the head turn right. I have hooked this up to my arduino by replacing the switch with transistors, but the head now will only turn right. Without knowing exactly how the circuit board inside the toy works, is there enough information to figure out what I'm doing wrong? [more inside]
I have an electric, piano-weighted keyboard that I want to learn how to play. I can't afford lessons right now. It has MIDI in and out connectors.

Looking for things in the $75-150 range.
How do I safely and (pretty) cheaply implement this one-off home electrics / electronics project? I have a low-wattage controller that will drive a high-wattage load having to do with the heating of water. I already have a GFCI extension cord that will stand between EVERYTHING and the wall outlet. The main complicating factor is that this is a single, custom-built thing so I need to use off the shelf pieces for a housing, etc. [more inside]
