smallest power jack socket?

I'm looking for the tiniest power jack socket possible for charging an internal battery.  I'm considering micro USB, but it's difficult to solder (and it would be nice if the plug didn't have an up and down direction).  Can anybody suggest alternatives?  Thanks.

Hi. Is there someone out there who might repair motor vehicle ball and socket joints or know of such facility?

I have such joints on a yacht's steering gear in need of replacement. Easy I hear you say but not so for I can't identify which vehicle they were intended to fit and enquiries to various manufacturers/suppliers have drawn a blank because of the taper required (imperial dimensions I believe). Only option would seem to be to have the offending part repaired. Any advice will be greatly appreciated. Regards Recrem.

Do you HAVE to have a socket for an 8 pin microcontroller or can you just solder it directly to the board? Answered

I'm trying to put together a Tv-B-Gone with the Microcontroller from ladyada but they don't send along the socket (I had the rest of the parts already from other projects and just needed the microcontroller and socket) and its not at Radioshack either. So I'm wondering how important that piece is? Can't I just solder it directly to the wires? Or is there something specific that I'm failing to understand? In a dire need to learn, thanks.

What is a good cable/socket system for modular circuits?

I've been working on and off on an integrated color organ and vumeter over the past few months.  Part of the design is that there will be a central "hub" that will do all the filtering and user interfacing, allowing me to build the display itself separately.  The intent is that this will allow me more design freedom in a display, since I won't have to fit all the circuitry into it.  It's also cool, since this project is more self education than anything else.  The minor problem is that I have no idea what type of cable or connector to use in order to make the design modular. So, is there a good cable/socket type for this purpose?  It preferably needs at least five wires (high, low, mid, left channel, right channel), which is why I don't think USB is a possibility.  Also, will it be necessary for one of the wires to be hooked up to ground of the central hub?  My intent is for the display and hub to have different power supplies, with the filter outputs hooked up to transistors in the display, which will in turn "trigger" the leds. Forgive me if this is a glaringly obvious question; I'm entirely new to electronics, so I have no experience with cables and the like. edit: the display is going to be at least a foot from the central hub, if not more, so ribbon cables and the likes are out of the picture.

Light Socket Extension help

Can you help me find a safe way to build a cheaper version of this: http://reviews.lowes.com/0534/3125483/reviews.htm?   Here's my situation: I want to convert double-lamped can lights into adjustable spotlights without making any permanent changes other than unscrewing a lightbulb and replacing it with something else.  It needs to be able to go back to a lightbulb very easily.  The cans stick out from the wall and each socket is oriented vertically, so one points up and one points down, effectively washing the wall up and down with light.  The wall of 8 or so are wired so the tops are all on one circuit and the bottoms are all on another circuit. The item from Lowe's works OK, but is $17 and more flexible than I need.  Here's what I started to put together:   At the top is a 100W Par38 spot light, screwed into a single outdoor metal lampholder.  That is attached to a 1/2" pipe (PVC or metal), about 12" long.  Now, at the bottom of the pipe, it needs to screw in to the socket to get power.  I either need to get an E27 lamp base onto that pipe, or use a two-blade outlet adapter that screws in, and get a two-blade plug that is rigidly fixed to the pipe.   Is there anyway to do this that the NEC would smile at?  Absent of that, a way that is still safe and secure, and safely removeable without changing the existing light socket arrangement?

What is the standard size dc input jack socket for music equipment i.e. mini amps and guitar effects gadgets? Answered

As quite a few people will have noticed (because i have asked so many 'beginners' questions on here) I am building a mini guitar amp. I am wanting to use a 2.5mm or a 2.1mm dc input socket, I was just wondering if there was a 'standard' size connector. I'm sure I have heard there is one size commonly used in guitar effects pedals and equipment like that. It doesn't really matter, because this is likely to be a one- off product, but if something breaks a few years down the line then I would like to be able to say i'd used the most common jack, so i can get a replacement.

I suspect they aren't that sort, because I think they would need more connections than these have. One has 3 solder lugs, the other only has 2.

Cardboard insulator? Answered

Thank you so much for these tutorials.These cardboard insulators are almost never seen in europe, is there a reason? Is 110volt more suitable than 230v maybe? I am in Europe.Do you think the electricity travel cardboard in the cardboard? My nations authority that decide standards for all electric products question the cardboard when i asked them, they never seen it.I am experienced with these sockets by now, but I got a shock when changing bulbs whilst the plug was in the wall the other day, metal socket with cardboard insulator. And I cant find the reason for it, the insulator on place and intact, the wires not too long so the bottom of the socket were touching either.In case I put electrical tape on the inside of the socket wall, between the insulator and the metal socket.Another question. Depending on how the connector plug is plugged into the wall the threaded white metal part on the socket might be the hot/live part rather than the neutral. Its slightly more risky if the threaded socket base is the hot one, but you cant really know unless you have special earth plug in usa or when using any plugg in the UK. Other non-earth plugs and any standard europe plug with only two pins are more risky.Does it matter do you think?
