chargers, or booster??

I was watching pages throught here watching the diferent chargers post, they all very cool like the one it was built inside of an altoids can... BUT they where all made out of bateries and none of them where made out of lithium ion cell phones like bateris and i was wondering if this proces was posible so i can try to make one what yall say??????

Black & Decker 18 volt charger not working

I have three Black and Decker, 18volt battery chargers, for the FireStorm series tools. One is an orange dual charger. One is the single black charger that came with the drill. And one is the Radio charger. The radio charger AC adapter case melted and no longer works. The single and double chargers both seem to kill batteries, and do not charge. I have voltage coming from the chargers, but I don't remember how much. Does anyone know what the voltage should be on the charger? More importantly, how do I repair the charger to output the correct voltage/current?

Non-Arduino Solar Charger

Do you think there is a great alternative to the current solar charger? Today, there are many DIY Solar Chargers that are alternatives to the current commercial products. Do you think there is a better design for a solar charger that is not run by an arduino?

Smart battery charger

I am trying to build a smart charger that will charge a Ni-Mh 2/3a 1200mah 9.6v charger. By smart I mean that it will stop when the battery is full, then if it drops below, say 9.4v, it will charge it to that again. Most of them also have a discharging button that will bring the voltage down before charging it. For the charger part I found this websitehttp://www.elecdesign.com/Articles/Index.cfm?AD=1&AD;=1&ArticleID;=1823Which details how to make a charger that will charge a 13.3v battery. Of course, mine is 9.6v, so it would have to be modified. The current "dumb" charger for the battery just gives it 12v @ 250ma. The smart charger also is powered off 220vac, which is not good because I live in the US. IS there a way to make it work off the 12v 250ma charger? Also, the circled components (the overlay thingy wasn't working), what are they? the no/nc one might be a switch, and the RL1 one could be...a relay?

Solar charger in altoids tin for 9v??

Well, if you have seen the altoids solar battery charger, and the altoids 9v usb charger, then you must have thought, "why not put em together???". Now, Im not electronics buff, but I'd be willing to bet that since the 9v charger instructable is so small, that it could be incorperated with the solar panel kit. Now, my question is, would i have to do anything ridiculous to convert the solar charger (which is ment to charge 2 AA batterys) into a 9v usb charger w/solar panel while still being inside an altoids tin. PS: I still don't know why I have this wierd fascination with altoids tin DIYs, but I do...

Hello I have a bunch of AA rechargeable batteries and would like to use them. I could just go out a buy a charger but wheres the fun in that. I would like the charger to be close to the ones you buy, but of course with the instructables finesse. it needs to charge at least 4 at a time and tell me when there charged with an LED indicator. id like to see if it can be plugged into my USB port and charge. Thank You John F.

Does the current of a USB phone charger affect LEDs powered by it?

 Here's the story: I was reading Instructables one day, and I had a BRAINBLAST. If I were to add ambient LED lighting to my room, a USB phone charger would be a relatively convenient power source! So I got to work. However, while using online resistor calculators to determine the resistor suitable for this project, I noticed that they did not require the source current. This got me pondering. So the question is: Does the source current matter? Additional Information: 2 USB phone chargers Charger 1:     5V 1000mA Charger 2:     5V 800mA Resistor: 1.5ohm 2W Metal Film Resistor LEDs in parallel LED:     3.5V 25mA Help would be greatly appreciated!    :)

iPhone Chargers

I have seen many 'ibles on battery-powered USB chargers that say they cannot charge iPhones/iTouches because they require power to be supplied to the data pins. How, then, have I seen iPhone chargers (that work) with only two inner wires - a red and a black?  I recently bought an iPhone charger, so I could cut the wallwart off and use it instead of a USB port in this circuit. However, I have discovered that it only has 2 inner wires, as previously detailed. How could I use a 9V (PP3) battery and a 5V (7805) voltage regulator to turn this into a battery-powered charger? Both of the above questions are ones I would like answers to. Thanks in advance, ~H4ZZ

Building a charger circuit for a coilgun by adding a bunch of smaller charger circuits from cameras together.

A while ago I ran across an instructable detailing how to connect a bunch of charger circuits from disposable cameras together in order to make the capacitors for a coilgun charge faster. I went about cutting the important parts of the circuit out of the rest of the PCB inside the cameras, but the instructable has since disappeared and now I'm left with a bunch of separated charger circuits that I need to add together. Does anyone know how to do this? The pictures are examples of what I've got. I have 11 of them.

Repurposing a Sonicare wireless charger into a Galaxy S3 charger- anyone tried that?

Hi All, I have a spare Sonicare Flexcare travel charger, which is used to wirelessly charge my toothbrush. I've tried to charge a Nexus phone with it, but it didn't charge - I think this can be for two reasons - some kind of incompatibility, or the distance was too high due to the little round bulge on the charger. Does anyone have an idea if this might work? I didn't want to remove the bulge before some inputs from the forum :-) To charge a Galaxy S3 I'd need an insert to stick to the battery, but that's cheap enough. Thanks, Daniel
