Hi, does anyone know what is the use of the -5V output from the 20-pin ATX power supply connector? I bought a computer case with Delta Power supply model DPS-250AB-4, a 250W PSU for microATX case and I noticed that this PSU don

Hi, just read your reply now. Thanks for the info. By the way, induction motors like those in the washing machine, dryer or refrigerator? ???

Hello, just want to know if the power outlet frequency will have a drastic effect on the electrical appliances? Say for example: - If I buy an electrical appliance from another country whose power spec is 220V, 50Hz, then I bring this item to another country whose power spec is 220V, 60Hz, will the 10Hz difference will damage the equipment or affect it in any other drastic way? I think those motor-driven/transformer-supplied appliances will be affected (like air-conditioner, fridge, TV, etc), but I just want to make sure. So please advise. Thanks!

Hi, thanks for the reply. So this simple signal amplifier is only practical to use if you have one or two tv channels that are weak? The reason of my inquiry because I have a set-top-box that converts analog tv signal to digital then it is fed to my tv's A/V. The problem is, I have 2 tv channles that are very weak and my set-top-box cannot convert it to digital anymore and it will just show a message "No Signal" for those 2 weak channels. So I am finding a way to boost the tv signal before it is fed to my set-top-box. Any alternative solution for this? Or the best thing is really to boost the signal before it's fed to my STB.

Hello, I saw a project here named "TV Signal Amplifier source: smartkit" and it says it will amplify weak tv signal. I was assuming that the purpose of this amplifier is to boost TV signal so that you can watch now an improved reception, correct? My question: If you amplify the weak TV signal, you will also amplify the noise or raster effect of this weak TV signal. So overall, you still have a very bad reception ?? It does not improve anything. Please clarify...
