I bought a set of Radio Shack Crimp-On Banana Plugs, but can't figure out how they crimp... they seem to be pretty thick brass... has anyone used these? if so, how do I crimp them?

(okay I am now having to retype this out as this stupid editor isn't working properly) I currently work at a dairy (or convenience/general store for you Americans out there) and I have been assigned the awesome job of phasing out the cash register with a fully fledged touch screen point-of sale system. This is how it goes: There is a computer 'out back' that controls the stock levels, reports and so on, and there is the touch screen system 'out front' that handles the transactions. These two computers need to have a constant connection between each other. We were going to use Wi-Fi but we found that it's too unreliable and not very secure. SO we are using plain old Ethernet cable. Now the problem: we have no router or switch so do I need to crimp the cable as a patch or crossover cable? And if someone could point me in the right direction to do this, that would be much appreciated (as everything I've looked at tells me something different every time). Cheers! (P.S I know CAT-6 is faster and more reliable, but I'm just using what my boss ordered)

Yeah, so, my brother bought a mid-80s Schwinn World Sport. It's a nice bike. I spent about 10 hours overhauling every piece of that bike. Unfortunately, when I got it all put back together and test rode it, the bike had a nasty pull to the right. Bent Frame. He didn't check that when he bought it (didn't know anything about it, I daresay). Anybody know anything about repairing a bent frame? The frame's tubes don't seem to be damaged or crimped or dented. I'm thinking of using a car jack and some straps to straighten it out. Any thoughts?

Not sure if Tech is the right place to post but it seems appropriate. I have been doing some breadboarding lately and in an effort to clean up my work I plan on making a box/panel with several commonly used components (potentiometers, audio jacks, DC jacks, other sockets). I would like to have some sort of quick way of connecting these components to a breadboard. I saw a post here in instructables on how to make Banana plug to breadboard pin jumpers. The only problem I have with this solution is that all of the panel mount banana plug jacks I can find are fairly pricey and somewhat bulky for what I want. Does anyone know of something like a panel mount breadboard socket? The components I will be using will have anywhere from 2-9+ wires coming from them so I would like a way to have some sort of socket or connector mounted with the component and use wires to connect to the breadboard only when the component will be used (as to avoid lots of excess, unused wires coming from my panel). A source of cheap banana plug jacks (female, panel mount) and crimp on male plugs would help as well, if I cant find another option.

Hello, Ever since i moved into my current home I have wanted to put in under-cabinet lights in the kitchen. Its a small kitchen but the current fluorescent lights are just not giving me the light I'd like. Powering the LEDs is my only concern. There are two under-cabinet areas each with one type of florescent light fixture with a normal 110v power line running into each light directly from a small hole in the wall (all hidden of course under the cabinets). There is no power outlet associated with these two lights. There is one outlet along the wall but I would not like to use this if possible as it powers the kitchen appliances, and it would show the power cord from the lights (Id love for these new LEDs to remain hidden.) I understand to use a 110v source I would need a LED transformer of some kind, I have seen these for sale, but I do not have an outlet that this transformer can plug into. Like this: http://www.ledstrips8.com/20-singlechip-smd3528-waterproof-aluminum-shell-rigid-led-light-p-118.html Is there a way to connect a type of transformer to this direct 110v line? Would I splice the plug off the end of the transformer and just crimp it to the 110v source from the wall? Like the end of this transformer: http://www.ledstrips8.com/led-power-supply-110220v-ac-to-12v-dcindoor-use-p-70.html Im currently at work but if pictures help I can upload them later. Thanks!

Hey Instructablonians! So after thinking about it for a while, I realized that my original Beating Heart T-shirt was a bit.... restrictive... as to what you could display on your glorious torso. As a result, I decided to embark on a journey to make a fully programmable 14X7 LED array display on a t-shit, which I call LED-shirt v2.0! Also, since I was making this portable and re-programmable, I figured that you should be able to go everywhere and still have some nerd "bling", so I included a charlieplexed LED binary clock. I drew up the schematic on eagle, routed the board, etched it, drilled it, stuffed it, programmed the binary clock, then soldered ALL of the crimp beads onto all 91 LEDs and female header (it's got to be detachable). I tried sewing some of the LEDs on via a sewing machine, but I bought the wrong thickness conductive thread, and the machine kept jamming. Then I tried by hand, and it just takes too long v_v. (I'm using Leah Buechley's method)I'm going to order the thinner thread and find someone with a sewing machine they're willing to lend me. Until then, I have this awesome blue binary clock that I can carry around with me!Oh, it's atmega168-based, runs @ 12MHz, and as of now runs off of 3 AA's, but I have plans to make it LI-ion compatible. Also, I have to thank Zach for the idea to make the 14X7 matrix - it's really a demi-charlieplexed 7x7 array.Oh, and if you were wondering, that's an aluminum rod w/ a captive ring next to the battery pack. I love lathes.-Muffin
