Please help me understand electricity and electronics. I have read the water analogy numerous times but I still can't quite grok it. Like "Ummm, Where does the water go and does it evaporate?" I have started tinkering with a Raspberry Pi and would love to build more complicated circuits with capacitors and transistors. [more inside]
I just picked up an IBM electric typewriter from a salvage shop. However, as you can see HERE, there's something a little bit strange going on. Any electricians out there who can give me some insight? Thanks!
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]

I'm about to teach a soldering class to kids, and it occurs to me that I may blow a fuse in the room that I'm doing the event in if I plug too many in at once... Any idea of how to gauge how many I can plug in simultaneously? This is the soldering iron I have. http://www.elexp.com/sdr_5258.htm Ideally, I'll plug in 12 at once... thank

What would be a good battery to use for renewable energy generation? If the anual average wind speed of an off-grid house was 6 m/s and had a roof at 30 degrees due south (for the use of solar PV). What kind of battery would you suggest I purchase so that it can be used for a turn key system and last for up to 3 days using wind power and solar PV? - The average power consumption per week of the house is 111.657 KWh [more inside]
I want to create a customized Settlers of Catan board. For the purposes of this question, it could also be a custom Monopoly board. I want the pieces ( cities / hotels ) to light up when they are placed on the board. I know I would put LED's in each piece, but besides that, I am not sure if or how I could power up the LED's. I am not an electrical engineer, but magnets, watch batteries or inductive charging sound good to me. Help me make an awesome electronic board game!
Just returned from fabulous 2 week holiday in New York. I Brought back Epson Artisan 800 All-in-One Printer from Staples costing $230. Unfortunately, I cannot use it in U.K., unless I plug voltage converter/transformer products. Has anyone else bought this set over there with more success? Any advice \ information appreciated. Please specify me What exact voltage converter product to buy & where to buy it from USA online store. Thanks. [more inside]

Carpets in new home are producing tremendous amounts of static and lots of sparks. What are good solutions to reduce the static to protect computers and other electronic equipment? Ideally, the solution would reduce the static across the entire house, as trying to protect each piece of equipment with an anti-static mat or some such would quickly become cost prohibitive.
