2x Questions - Techy

First question - Does RadioShack sell female USB ports? Ones like those that you would use for a mouse, so I could plug in a USB powered device (mp3 player) to charge through, say, a car or wall? It doesn't matter what other type of end it has on it, I'm just going to cut it off anyway. 2nd - Does RadioShack (that's the only electronics around here) sell power adapters, you know, that plug into the wall and output DC power, that output around 5v of power and around 500mA? I'll probably go 'round to garage sales and stuff to find junky electronics, but would like to know if there was an alternative if I happened to not find one. Again, 'tis to be used as a charger for my mp3 player. Thank y'all for your help!

Ideas and a Question

I have a couple of suggestions for new instructables features. Here they are.1. Add a button for rating the difficulty of an instructable, and one for how long it takes. Put them beside the rating buttons.2. Let me add groups to my favourites.3. Create somewhere where people can sell their creations, kinda like etsy -- Loads of people are selling stuff on etsy, and could be doing it right on instructables.***NEW IDEA*** 4. Find some way to get rid of the ads. They keep confusing me.And finally, a question:Is there anywhere where I can buy an instructables multi-tool or shirt? Or do I have to win one? If there's no shop, there should be one.

How discover time travel... i think

Long story short, my friend found some instructions of how to create a time machine or something. The drawing looked kind of dirty so instead of keeping the drawing, she just took a photo of it. She showed me the photo, which turned out to be real blurry and crappy.I posted the blurry photo up on this site, and someone commented that the original image is on a site called asiko.org It's some weird $h!t. I emailed them but never received any word back as to who is behind this. But anyway I figured to post the instructions here because it does seem feasible. The plan is basically this:1. Choose a date, time and city. These 3 things are called Asiko. Let's use 01/01/09, Time Square NY, New York just for clarification purposes.2. Popularize Asiko till step 53. Meet at Time Square on 01/01/09, and we should see a time traveler from the future4. In the unknown future, a time machine will need to be invented. Still popularize Asiko, 5. When they figure out how to have "safe time travel", a traveler will be sent back to the popularized location and time of Asiko, which is Time Square, 01/01/09.

Underground Webcam

I have a problem with the city Department of Public Works. There is a collapsed culvert in my backyard, which causes my yard and basement to flood. I am trying to come up with some footage to prove to the city that the culvert is (FOR SURE) collapsed in the middle somewhere. I am thinking of constructing some sort of wireless web cam / led light setup that i can push up the length of the culvert to record what is actually going on to prove to the city that they DO have a problem and where exactly it can be found. I am thinking of a rugged sort of wire (similar to a coat hanger) and a 2 liter bottle (or similar) to house the cam and some small led flashlights. The device will need to be pretty small... have light and be able to stay somewhat upright so it won't flip upside down once in the "tunnel". I am looking for some ideas on how to execute this. If you have any recommendations, please send a shout my way. I would love to get some great proof to head straight down to the DPW and see what they have to say then.I have even called the local news team to help me with exposing the problem. To see the story that was on the news, go here...http://www.youtube.com/watch?v=CpjGmS9GJ_wThe photo shows the receiver and the wireless cam i am thinking of using.Or maybe i would be better off using a wired cam, due to the signal loss of being underground, either way, i have some really small cameras i can use, it is just a matter of the housing and the lighting... and a way to push it and make sure i can get it back later.

A central non-electric grid electricity storage system for solar and wind energy with future expandibility

I have been thinking and reading about building a system so that I could surf using a laptop, charge lights, charge mp3 players, mobile phones, rechargeable batteries so that if possible they would not need electricity from the grid, rather that would be optional when there would not be enough power that was found otherwise. I had first thought to work this out in a group as a kind of project, as there are others but I don't really know that many people with those skills. The idea is that you start very basic, with say one solarcell and the electronics. The electronics should allow plug to when you wnat to have the money you can add another, in serie or parallels so they give more power. This can then be plugged in to a system that stores that electricity in batteries. The system should also be so that it allows to connect for example one or more small selfbuild wind turbines, like the ones found here, so that in the best case you get electricity from both, or one of both but with the possible option to get electricity from the grid so that if necessary you can charge something from there. That would mean it would include an electricity meter, and maybe the possibillity to add that self powering powerplant as well.So basically you have two projects. Or maybe three. The casing to add small solarcells in, and then be able to add several casing together. The electronics to put them in serie and then a central electronic system, which allows to connect solar casings, self build windmills, batteries, the self powering power plant, possibly the possibility to add it do the grid, and last but not least the possibbility to charge things. That could be a seperate part of electonics. As one of the things I had been thinking about is to allow to connect fuel cells to it. I prefer us in what already exist, so I would suggest using the following instructabels projects or learning from them:a Savonius Wind Turbine,Ted Baer's Bicycle Wheel Windmill, savonius windmill alternator,introPringles Wind Turbine,DIY 1000 watt wind turbine,A remote controlled power RGB LED mood light,Power LED's - simplest light with constant-current circuit,Circuits for using High Power LED's,personal powerPlant, ... others may follow laterLike for example the Charge Any USB Device by Riding Your Bike but then connected to the portable usb batteries, so they could be also connected to the central charge unit. The connectors could be usb connectors. I saw some time back a connector which had a 4 port usb block attached to it, but other connector types would be usable as well. In adition, it should be able to switch on automitcally when the sun goes down, but allow a control a button or remote control to trun them manually off, so that no needless electricity is wasted. I know this is a lott at once, but its more my kind of thing to work on more complete/complex systems. The lights that would be used with this would be led lights, powered a la sunjar, using the same technique. So that them turning off and on, is mostly controlled by the sun going up and down. My idea was that with such a system, I could add piece by piece, and still have light, and electricity indepency from the grid, and I would know the cost, so that once I would have bought the pieces it would generate electricty whitout to much further cost.Solarcells would typically provide 8V or 12 V, this could be smaller ones, the casing would be is supose made of plexiglas, with pieces that standup to keep them appart, and holes for the cables, and a backside, that stays dry as well. This is what is on the drawing: the solarcells feed into the sersol which puts them in not parallel and then transport the current to the cen1 which directs it to the batteries to store it. The same for the windmills. But they go to the windmills, which puts there current in not parallel. The powerreg, regulates the power of the personal power plant, it can discharge, but also just regulate. There is connector to the grid, so if there is no electricity or not enough electricity it can be taken from the grid. There is the possibillity of a remote, which would work in connection with the cen1. The batteries might need extra electronics to see which one is full and to divert the current to another battery, and to get current back to the powersockets which could be regular oens, but also preferably usb ones. The other two connections could be for for example fuel cells, or something else. The control solar cells is simply to turn the connected sunjars which may still each have there own solarcell, on or off by the rising or going down of the sunn. The remote, is to turn them off manually.The casing should be sturdy but not to expensive, it may have to include somethings to keep it right, but the idea is to be able to put them after glass as well. The idea is that the electronics design would be free, or very cheap, so that people can build this themselves, the casing shouldn't be to expensive but that can differ on taste, most parts or thing likes windmills would be the DIY type or possibly ones you can buy as well, and most parts would have to be, off the shelf. I'll try to add a basic drawing, and some sketches, to give you a better idea. I'm not that good at that, i'd admit.

Inductor Usage

I have an 10mH inductor pressed against the active line of an extension cord connected to a load (a washing machine) that produces 9 amps. How do I measure the voltage produced by the inductor? Does it need to have a current already in order to react to the magnetic field? Does the negative lead produce a negative AC and the positive frequency such that if I attached a voltometer I would get a 0 reading? That's what I am getting even on my voltometer, even on the finest setting. I should be reading 0.09V, I believe.

New car sub, does this work?

My cousin was nice enough to give me this nice little 200 watt 12 inch sub. It just needs some minor repair, theres a little puncture hole in the dust cap, simple fix. I tried hooking it up directly to my stereo and using the eq to filter out all the freq and still wasn't too happy. I took the amp out of my mirage sub and wired it all up to this one, the amp is only 75 watt rated, well I could be wrong, all I know was that the sub was 75 watt. But it works great, tell me if this is a good idea guys, lookin for opinions. Also too, is it normal that the heat sinks on the amp should be "energized"??? I picked it up by the heat sinks while it was plugged in before I had the sub and dropped it rather quickly, althought it seems to have loosened the joints up in my hand. Also too, does anyone know what brand of sub it is? All it says on the front and magnet is VR with a 12 in between (12 inch). I wanna find some specs for it as I'm not sure if the box it's in is tuned for it and I'm thinking about porting it or would that make it overdrive if it was ment to be in a sealed box?

a DIY optical port

I have been intrested in optical computer for a while but found them rather expensive to build so I tried to look for cheaper ways to build some key features like the gates. The basic idea is to use solar cells that power a led. For and OR-Port you use solarcells where it is enough that one of the side gets light to make the led burn. To make and AND-port, you can put a resitor in between so that it really needs the power form both channel sot make a led burn. For a NOT-port you put an invertor in, so that when it burns it gives no signal, and wheren it does not receive light it burns this because of a battery it caries. A NOT-port is almost like a led-throwie.I do hav emore but wanted to know if this would be a good place or not, or if someones intrested in hearing on how to build a full optical computer, still basic, but almost completly optical, or if it would be better to post this on the microprocessor group at the opencourseware of the MIT ?
