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 bought a few of these for a motorcycle project. I need to hook it up to a little arduino, but i'm used to breadboards, how does one hook this up? Do I need to solder these little connections? Btw, the project is to make custom signals tail lights for a motorcycle. I bought these hoping they would convert the 12v of the bike to 5v for the arduino.
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]
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?
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]
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]
I am packing my entire house and moving to the UK, and I'm hoping to bring my TV, stereo, and a few smaller appliances with me. Please help me figure out my US to UK transformer and voltage requirements! [more inside]
Can I safely use a 5V 2.1A power adapter for a device (Linksys WET11 Wireless Ethernet Bridge) that expects 5V 2.0A? [more inside]
What kind of potentiometer do I need? Electronics and electrical math confuse the hell out of me, so I'm just going to lay it all out. [more inside]
DC-powered DVD players? I'm living in a country where the AC power is 220 volts, but will be returning to the US, where AC is 110. I want to buy a DVD player that I can use here and at home. [MI] [more inside]
Voltage query: What are the disadvantages of regularly using electronics made for 110V using a step down voltage transformer in a 220V - 240V country?
Global citizen looking for either 240V only or bicurious with 110V CD Clock Radio in NYC or via online sites. O' Wise Ask MeFi, where do I find the perfect alarm clock to wake up with when in Bombay? I'm not yet desperate enough to make exceptions for 110V clocks in drag using a voltage convertor. [more inside]
