There have been a lot of CPUs that did not feel much love: the 80286, the AMD Bulldozers, the Celeron D, but the one that got absolutely creamed in public opinion was the IDT WinChip. Which is ironic, as it was a...
This cable costs $200 so I want to build one. I know where to get the round silver plug at right which is a 7 pin Amphenol and I know the pin designations inside.
I'd like to know if the left white electrode input socket can be found anywhere or it can only be made special at factory. Have you...
I have a power strip that has fallen from height accidentally for a couple of times, there is no observable crack or damage, however, could this lead to bad contacts or anything bad to the

Hi all,
25 year electrician here with a strange (to me) issue.
I have a science project lamp that has a dimmer, a volt meter and a socket with a bulb in it. The kids can turn on the bulb, rotate the dimmer and watch the voltage go up and down on the meter. Simple enough.
Every dimmable bulb...
Hi everyone, I have just started learning sockets in python and I have made the following code:

Hi
right now I do not have school but I was thinking about what my chemistry teacher said last year.
he was telling us about electrons and how they move from negative to positive. he said something along the line of: let's you would put a fork in a wall socket and by chance you first hit the...
There is an interesting video @ Facebook about a potato that is made into a light socket & battery:

It's mid summer and I think I need a project to keep busy. What better than a solar project? Problem is, I've never built a solar circuit before, let alone a battery charger. Ideally, I would like to build the equivalent of a solar powered generator. I know there's no way I'm getting as much...
Hello,
I was trying to check with a voltage tester if there was voltage in a light bulb socket (Edison type, no bulb present). Explosion happened (a relatively loud sound) and the safety circuit switch turned off.
My question is, how can one explain this with the laws of physics and how can...
My son occasionally pulls plugs from powerpoints. We tried to get a powerpoint cover but the strong tape here in Japan is weak and it fell off easily. I was just wondering how much electric shock he might get from pulling out the cord when the device (a fan) is operating. Its a two prong...
It is safe to add on extra socket by this way?
Original connection:

Add-on connection:

The extra socket is for light usage only. Water heater is instant water heater without tank. The switch is double pole single switch.
If I plug my electrical device in the socket in any direction the device works. If i plug the device in opposite direction, it makes no problem. while the current in the socket is coming in hot wire.
Is there hot and neutral also in the wire connected to the device or they are both hot ?
Hello,

A 23-kg sign is suspended from the end of a 7-kg pole that is 4m long. The pole is partially supported by a cable that is attached at a point 3m up along the pole from the socket. The angle between the pole and the vertical wall is 60°, and the angle between the cable and...
There is this new electrical device called the Neo Socket Automotive Power Factor Corrector supposedly made by the Japanese company Miraizu that can be plugged into an automotive lighter's electrical socket which can increase the power factor of the AC electrical devices of a car. Power factor...
The Sandy Bridge processors are not significantly faster than the Nehalems, and they only had dual-channel memory. There is a noticeable difference in performance, but it really isn't worth upgrading.
Hopefully, the HUGE performance boost will be with the 8-core/22nm "Ivy Bridge" processors. I...

Greetings –
I have 5 (somewhat related) questions –

2) I could plug an AC cord up to the socket and if I do this – on a standard male plug...
