Can I use light switches to control mains plug outlets?

My room has only one outlet. What I want to do is fix 2 plug sockets to the bottom of my desk and then have everything electrical connected to that through an extension lead.  However, as these are at the back of the table I want to install light switches at the front which I can use to switch the outlets. Is this allowed/safe? The switches I have are single pole. This picture is as seen from underneath the table.

Compaq and HP laptop power cord compatibility? Answered

The plug for my HP laptop's AC/DC adapter has a loose connection, so I am using my old Compaq adapter.  All the specs are the same; 65w, 18.5v, and 3.5a, except for the input amps, 1.7 on one and 1.6 on the other (probably just because of efficiency).   The plugs are the same.  I just wanted to double check.  Is it okay to use the Compaq(actually says HP on it) instead of the HP one?

Is this legal? (UK electrical appliance question) Answered

Kitewife just bought a Christmas decoration, but when it came out of the bag, the connection was as shown in the image. The loose wire is already a safety concern, about which I shall be contacting the store, but I also I thought that appliances sold in the UK had to have a plug moulded onto the power lead? Since the decoration is lit with old-style filament bulbs instead of LEDs, I am wondering if she has been sold something that has been sitting in a warehouse since before the legislation changed?

Why isn't my new cigarette plug car adapter working? Answered

I got out my multimeter and did some testing: the socket itself produces power, but the plugged in adapter does not. The weird thing is that I tested it before with the car running and it worked. Is there some special way to plug this thing in that I'm not aware of? Any help would be appreciated.

How to connect a 12v/5v dc converter to a standard 12v plug? And still use the plug?

I need to power both a Raspberry Pi and a 12v touch screen from the same 12v source. I know that I can use a dc voltage converter (like this one: http://amzn.com/B00GQ4DTGQ) to step the voltage down to the 5v for the pi. The power supply has the circular 12v adapter (e.g. http://amzn.com/B00GUBVI9K).

Current and voltage ratings in dc plugs and wires? Answered

I had this great idea to turn old cell phone chargers into DC extension cords.  Cell phone wires are nice because of their curly spring wires.    I worried the wire gauge might not be large enough to handle my project.  Here is my question.  On websites that list current ratings for standard wire gauges, they list current limits but not voltage limits. Why is this?  If a 22 gauge wire can handle .92 amps does it really not make a difference whether it is 1 volts or a million volts?  Why don't they use watts to list how much power a wire can handle.  Watts take both volts and amps into account. Another mystery is that my DC plugs are rated for 6-10 volts.  Why are the plugs rated for volts but not amps?  What would happen if I used these plugs for 4 volts, which I plan to do.   Thanks -Jacob

3D Motion Tracking System - Plug and Play

We're working on developing an electronic personal trainer. When we started, we couldn't find an easy to use, plug and play system that could collect all the data and give us the measurements we needed... so we built one ourselves. It's comprised of three 3-axis MEMS sensors to provide 9 channels of data, an onboard microcontroller, rechargeable battery system, and bluetooth module to make a complete 3D tracking system. Is anyone else out there working on motion projects that could use something like this?

How can I indicate a USB charge with an LED?

I've seen some USB ports/chargers out there that have an LED that lights up when you plug the cable in.  Is there a simple way to do this?  I need the LED to light when the USB cable is plugged in, not when the charger is on.  So I could plug in the adapter and nothing would happen, but when I drew current to charge something, the LED would light up.  I can't figure out how to do it, so I'm asking you for some aid.  Thanks

Microphone wiring? Answered

I have a broken microphone. Its wire is cut  inside the insulation. i want to replace the entire cable. when i removed the plastic cover of the microphone i saw a red and a black wire soldered to it.  Therefore it uses only 2 wires but in the connector it is a TRS one not a TS one. i will also replace the connector.  i am wondering how should i wire a TRS connector which has 3 leads. one being the common ground. but the other 2.  should i short them out and connect the red wire or must I connect the wire to only one lead?  Then if i buy a $0.2 TS connector and i wire it accordingly. will it work? One another question does the microphone device has polarity that is should i connect  positive to positive and negative to negative lead. because there is no indication on the Mic?

How to build a circuit that switches between battery or AC, like a boom box (for lack of another example)?

I am designing something which will be lit by led's, and I want the device to be able to have the option of operating by way of either batteries(for the led's), or by plugging it in to 120V AC(the led's are the only things that will be powered). I know how do what I need to change the AC to DC(correct drivers etc.), however, I don't know how to design what I need to simply make it switch over to batteries if you unplug it from AC(automatically, as a boom box does if you remove the AC cord), or vice versa, switch to being able to plugging it in if batteries are dying/ are dead.

How do you build a fluorescent light from scratch and have it plug into the classic American outlet?

I am not asking how to build the bulb. Just attach the bulb+ballasts+plug it in. I want to build several letters out of fluorescent light bulbs, for example one letter is O but it will look more like []. I want to use bulbs that are 2-4 feet long or what ever is easiest... from scratch (without buying light fixtures and taking them apart). Each letter will be constructed of 4 lights. I know that I will need to solder parts together, I will need to buy ballasts, and bulbs... But construction wise I am semi lost. Also I would like recommendations as to how many ballasts for the bulbs, I don't mind if some of the bulbs flicker. Lastly I want the bulbs to make that humming noise so if you have any idea how I can induce that other then leaving the ballasts running for a while please tell me. Thanks, -Oliver
