Capacitor identification 2	18 Jul 2006 12:31 GMT	11
http://www.hucker.plus.com/temp/cap2.jpg Removed from a broken (caught fire!) fanless power supply (fanless PC power supplies are NOT a good idea - Yesico was the manufacturer if you want to avoid them). It was right next to the AC input, so I assume it's a filter capcitor (to ...

5 volt supply straight from 240v AC mains	18 Jul 2006 11:43 GMT	35
Please may I ask what the arrangement is when you see a single LED powered straight off of a mains power supply without any transformers or switch mode circuitry? In other words, totally uninsulated or regulated. I have an old computer with an external hard disk which needs about ...
AC socket/wiring questions	18 Jul 2006 07:14 GMT	18
1. Is the Hot wire more insulated than the neutral? If so, why? If the current is the same at all points in a circuit, the neutral wire will carry all the current coming in from the hot wire back to ground...so why have less insulation for the neutral wire?

coil gauge	17 Jul 2006 13:30 GMT	6
HI again, I read on the internet that depnding on the gaude size lets 18, it will take more amp to generate the same EM strenght as with a 30 gauge. considering there are the same weight of magnet wire to do the coil.
Fuse for 24V Transformer	17 Jul 2006 11:52 GMT	5
I'm wiring a remote ON/OFF switch for a large room (window mount) air conditioner which is otherwise accessible only via a 8 foot step ladder. Historically, everyone has been going to the fuse panel to do this. I need to use a low-voltage 24VAC control circuit to keep

square waveform (555)	17 Jul 2006 02:10 GMT	6
Just liek to know if it is a normal thing that at LOW frequencies ( 15-25 Hz) that the output of a 555 timer is not exactly a square wave. At higher frequencies I get a perfect square wave (say between 50 and 300Hz). But at lower frequencies, the voltage when get to high, slowly ...
