Power Tool Corded to Cordless

Hi 'nstructables I'm building a hovercraft (see several tutorials on Instructables - the one with a leaf blower) and my leaf blower is corded. I don't want to buy 25 miles of Black and Decker High Power Extension Cabling so I'm planning to convert to cordless. Here's my idea: (in visual) Is there anything I need to add? And if so, how do I make the "12VDC-240VAC" inverter described? My blower is 1600 watt. Thanks for any help! (Black and Decker)

Looking for a iTouch USB cord wiring diagram? Repairing the USB cord

Hey, I have two old USB cords form my iPod Touch laying around, and I took one apart to find that two of the wires simply pulled free of the part that goes into the iPod. I'm not willing to risk blindly soldering them back on and hopefully not frying my iPod to test it out, without at least a few tips as to which wire goes where. Could anyone help me? The four wire colors are green, blue, orange, and white. Orange and white are the ones that pulled free. Thanks :)

how can i make a ethernet cord splitter so i can hook up two computers to my one (cable one) modem?

I have a desktop in two rooms of my house and only one modem with just one ethernet port on it. so i can only hook up one computer at a time. i need both desktops hooked up and dont have the money for a modem with 2 ethernet ports on it. i have lots of extra random cords layin around. i usually can figure out how to do this sort of thing but im stuck. my modem has the cable home phone and internet all on it and it all has to b plugged in for anything to work. i got the cable to another end of the house by taking a short cable cord and plugging it into a splitter. so i could run a cable cord to my living room and my other room without having to pay for extra rooms. but i cant do that with the internet and i need to know how. can someone please help me?

A/V Cord to Typical Stereo Wires? Answered

I have a surround sound speaker system that only takes the typical stereo wires (you know, positive and negative electrode inputs for left and right side). I also have a stereo reciever that only provides A/V outputs. I was pondering how I could make these work when I realized that, even with an A/V cord, it still needs to make a complete circuit. Thus the cord needs to have two wires going through it, and the plug had a way to complete that circuit. Now that I know this, I want to know if I can cut the plug off of one end, strip the wires apart, and plug those wire ends in my subwoofer? If anyone knows if this is possible, please let me know! And please help me determine which wires are positive and negative current. THANKS!

Can I cut the end of a computer keyboard power cord and connect a USB cord to it?

I just got into electronics and I really like LEDs. I started looking around the house for some, but I might just go buy brand new ones. Well, I still have my old computer and I took apart the keyboard for LEDs. Instead of trying to take the LEDs out of it, I decided to keep everything together. The power cord is connected to the other board thing (a motherboard or baseboard?) It is one of the kind that have the 6 long pieces that makes a circle-like shape. I want to know if I can make that end a USB. www.quarkr.com/app/upload/product/20090525/image(962).jpg I see that in this image this is something that I want to do. But everything from the keyboard is still connected. I hope I am explaining this clearly enough.

Wiring an indoor extension cord to a small switch?

Hi - I need to take an indoor extension cord like this and wire it to a switch like this. I'm assuming I can just cut one of the two wires within the extension cord and connect either end to a prong on the switch.  Actually, I'm almost positive that will work. The real question here: is it safe? So, will this switch be able to hand the electricity from the outlet running through it? Thanks, Adam

Laptop "plug" upgrade/replacement question.?

I have an Asus K53SV Laptop and the power jack is busted, like the internal connections are loose.  I'm looking to upgrade it to a panel-mount one that's screwed into the case instead mounted to the mother-board. How do I find out which kind to order online?  It's not like I can go to the barrel-jack store with my laptop brick and see which one fits.  Is there a standard sizing scheme or something?  I couldn't find one. Also, is there a MagSafe like system for this?  I'd love to have it come apart if someone trips over the cord (again... that's why it's broken now... >.<)

Old hard to find cord`s circuit?

So at my school we still use old old programmable relays. The Crouzet Millenium 2. The problem is that we are plugging in and out the cords each day which leads to as you can think, them to stop working. My teacher can not find them and I am sure the school does not have the 100 ish dollars to drop on one cord. It is part public school so its not the richest. If my teacher had at least the whole schematic for the cord, then he can make his own cords to at least let us us them without having to upload 50 thousand times to try and get a response from the things brain. The cords model number is 88950102 if this helps

Dedicated cable release cord for iPhone camera

How could I make a dedicated cable release cord for the iPhone?  I have looked and looked for this end product - but cannot find it anywhere... Knowing that we can use the volume up button on headphones for the iPhone/Touch to snap pictures, how could we make a cord that is dedicated to this function (instead of using earbutds).  I am wanting to use this feature to help with making stop motion movies.  Using the earbud control is useful.  But I'd really like to have a cord a bit longer than the standard earbud cord lenth.  And also would be nice if the cord could have a very easy to press buton.  Clicking on the headphone volume control can be sort of akward sometimes.  Perhaps we could take some old earbuds and cut off the earbuds and do something with the remaining wires and make a some sort of switch with the remainder. Any thoughts?  I am pretty sure that I could waste an amazing amount of time and figure out via trial and error - but thought it might be better to ask for some quick direction! I believe that the more recent models of iPhone/Touch use a TRRS plug as described on this page:  http://en.wikipedia.org/wiki/TRS_connector Any thoughts  - THANK YOU  VERY MUCH!

My Laptop Is Broke. But how? Answered

I have an old dinosaur laptop (a Fujitsu Life-book C2330 approx. 7 years old.) that worked up until very recently. I packed it up in my closet for a few weeks, and when I decided to re-purpose it, the laptop wouldn't power up. I believe the problem is not in the laptop itself, but in its power transformer. When the transformer was working, it would make a high-pitch, low volume, whine. But now the transformer only whines once for a half second every five seconds. This could maybe be attributed to a blown capacitor or other electronic mishap. If that is the case however, it would probably be more worth my time buying a new transformer. My second idea is that the transformer has been damaged but usable for a while, but the laptop requires a slight charge of some kind in the battery to get it going, and the old transformer doesn't have the guts to give that charge. Metaphorically leaving me with a car with a dead battery, trying to jump-start off another car with another dead battery. If this is the case, then I should buy a new battery. My third idea is that both the transformer and the battery are not the problem, and it is the power jack that is the problem. I had to open the computer up not too long ago to re-solder the loose power jack. The screws that attached a ridiculously large EMI cage to the motherboard were stripped, so I had to drill them out, and then bend the EMI cage about 45 degrees. That allowed me to fix the power cord, but it also damaged my internal wireless card. After putting it all back in one piece, the laptop worked fine until I bought a new one, when I put it in my closet and forgot about it. Which brings me back to the thought that the power jack is broken. But it doesn't look broken at all, it doesn't feel broken, and it doesn't jiggle in the laptop. And if the jack is broken, I might as well just give up. The last possibility, is that the laptop, the transformer, the battery, and the power jack are all usable, but the power cord, which looks fine on the outside, might have lost its conductivity, or become frayed and detached inside its rubber casing. Which can be easily fixed by opening it up and reattaching the wires. That's my situation. I don't know which of these ideas it is, but it has to be one of them. I appreciate any help I can get. Sorry for the bad image quality. Not that the pictures help much anyway. Thanks, Sam

How to build a circuit that switches between battery or AC, like a boom box (for lack of another example)?

I am designing something which will be lit by led's, and I want the device to be able to have the option of operating by way of either batteries(for the led's), or by plugging it in to 120V AC(the led's are the only things that will be powered). I know how do what I need to change the AC to DC(correct drivers etc.), however, I don't know how to design what I need to simply make it switch over to batteries if you unplug it from AC(automatically, as a boom box does if you remove the AC cord), or vice versa, switch to being able to plugging it in if batteries are dying/ are dead. Thanks.

Circuit board assistance for a beginner (corded phone hack)?

I'm attempting to hack an old corded phone into a two button device in a smaller enclosure. Reason being my apartment uses landline phones to buzz people into the building, and I wanted to see if I could DIY a fun alternative. As it stands the functionality of two buttons is needed - speaker to answer/hang up, and the 9 key to buzz in - but the board itself is larger than the enclosure I had wanted to put it in. Is there a way to get around this? Would it be a matter of having to trace the circuits and physically break off pieces of the board that aren't relevant (keys 1-8, etc), or do I have it all wrong?  Pictured below is the board and the two buttons in question. EDIT: I accidentally circled the key below the 9 key - I'm aware of this mistake. I am a total newbie when it comes to this stuff so if this is a dumb question I apologize in advance. Additionally, if anyone has alternative solutions or suggestions for this issue I would love to hear them. Thanks!

Dell Insprion 1100 power jack negative positive pins?

Hi all, I was given a Dell inspiron 1100 with the charger and as I went to pull out the power cord from the the power jack at the back the wires ripped leaving the end of the plug still in the power jack at the back. I removed the end part and am now trying to figure out what pins of the 3 are what.It is a 3 pin jack all them are numbered 1,2 and 3.My problem is when the wires ripped out they left no evidence of what goes where when I tried to put them back in..Another problem is that the cord from the adapter only has 2 wires,centre and one around it,so two pins must be the same?.I placed smaller wires into the connection pin holes and glued it so later on  its easier to connect them up to the cord as the wires from the cord are thick and too hard to get back in the end connection. Can anyone please help me identify the 3 pins? Cheers

What DC adapter does this clock use?

 Someone was throwing away this HoMedics ss-5000 alarm clock, and I "rescued" it. The DC adapter wasn't with it, though, so I want to find a replacement for it. (Without the adapter, it won't give any features besides the time and temperature.) Might any of you possibly have this clock and/or know what specs its adapter has?  Thanks,   Win Guy P.S. I'm sorry that the photos are sideways, the camera I used auto-flips images that are taken at an angle, and that was the only way that I could take the pictures without the flash coming back and glaring in the lens.  UPDATE! I found a really old variable voltage adapter, but it has a fixed amount of amperage: 300mA. In any case, today I'll open the clock and check the polarity. From there, it'll probably be smooth sailing. Thanks to everyone who responded to my post!  But this question is still open to people who have this clock who can tell me exactly what the specs are.

Potenco's Latest Pull-Cord Power Generator - Wired Video

Check out Potenco's latest pull-cord generator in this interview Colin did for Wired. Video: Potenco's Latest Pull-Cord Power GeneratorA couple of weeks ago, we headed out to Potenco's amazing headquarters at the decommissioned Alameda Naval Base to check out their power generator for the developing world.It looks a bit like a yo-yo, and generates an average of 25 watts of power in normal operation. That's enough to power twenty minutes of cellphone talk time with just one minute of pulling.Their engineering feats could ultimately enable millions in the developing world to access information through their cellphones and internet devices, and light their homes with smoke-free lanterns. Now all they have to do is get them out into the field.One proprietary thing we couldn't show you was the Potenco cord testing room, where a Rube-Goldberg looking machine put dozens of types of strings through thousands of simulated yanks and pulls.Nicholson Baker envisioned such a machine in his book, The Mezzanine, but for shoelaces, not power generators. We echo his thoughts on the relationship between finding the right strings and civilization's advance: "He had constructed a machine and strapped hundreds of shoelaces of all kinds into it, wearing them down over and over, in a passionate effort to get some subtler idea of the forces at work... Progress was being made. Someone was looking into the problem."Enjoy the video! Thanks to Potenco (especially Mike Lin and Colin Bulthaup) for letting us come out and Michael Lennon and Annaliza Savage here at Wired for putting it together.
