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]

Voltage converter / inflating an air mattress to be used in Italy: My friend, a sculpture instructor in Florence, Italy, is putting us up and guiding us around the city. Very cool. He has asked that we bring an air mattress with an electric pump, which he will later use for camping, also in Italy. [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.
