USB charged USB charger?

Hey all,      I'm looking for a combination of 2 circuits that I know exists already. I want to charge a Li-ion battery via a USB port in a computer or a wall adapter. Then (to save space and be more streamlined) I want to be able to use the same USB connection In the device I'm making to charge my phone from the Li-ion battery. If anyone could point me in the direction on this circuit that would be greatly appreciated.     Thanks

USB to Arduino USB Wirelessly?

I am currently working on a robot that has a deadline in about a week, and so far, there is only one problem we haven't solved yet: Communicating with it without a wired connection. Currently, we have a program on a desktop send the Arduino the gcode via USB cable. What we would like to do, is send that information without actually having it connected with a wire. Originally, we were going to have a Bluetooth module connected to the arduino directly, and have the desktop program communicate with it. Unfortunately, due to time constraints, we haven't managed to get it working, and would like to move onto plan B: communicate through the USB port, and essentially leave the Arduino untouched.  I did a little googling, and I wasn't able to figure out very much on Bluetooth dongle -> Bluetooth -> USB that was actually positive and helpful. Currently, we have a few HC06 bluetooth modules lying around, as well as a few spare Arduinos. I was thinking of connecting one of the modules to another arduino, connect that arduino to the robot's arduino, and communicate with the first arduino via the bluetooth. Essentially, the first arduino would be an interface for the second one. Would this work? How would I go about doing it? In short: What would the best method to communicate between a PC and the USB port of an Arduino wirelessly be? Anything helpful is always appreciated, thanks!

I stripped the cable (it was male to male), and tested the output with my multimeter, too. I am getting about 5vdc, is that normal? I thought I got more out of the USB port. Like I said, I was wondering about any opensource usb control program I could use to control the USB voltage. Is this even possible? Also, I can't program AT ALL, or understand it, either.(if it matters)

USB generator

I am building a small crank-powered generator for a college electronics class that will power a USB port. I know a USB port supplies 5V DC, and that my generator will obviously produce AC current, but I'm not sure the best way to convert AC to DC, then how to step my voltage up to 5 volts. My generator uses 6 wire coils in a circular pattern. 12 neodymium magnet rotate over the coils. This doesn't seem like the most efficient design ever, but that part is a stock university kit, the wiring is up to me. I've only been able to test each coil at a time, and each one produces .5-.7 VAC. Do any electricians out there have some tips? When all is said and done, I'll definitely be posting an instructable on this.

Question by MACKattacksnipe 


USB heater

Hi everybody! As sais in the title of the topic, I want to realize a USB heater. Let me introduce you to what I think. Last week, I was in the store near high school with some friends, and one of them told me : "It would be cool if we could heat up things in high school, to have like a mini oven directly in our locker, working with battery." Of course, the idea is not to install a oven in our locker, firstly because it would need an incredible battery, and secondly because it would be pretty dangerous.... So here is the idea : the goal is to heat up at least 2 chocolate breads at 60°C. The heating time is not very important, but it has to be under 40 minutes (a system will start the oven before our break). But here is not the most complicated : the oven has to get its power from a usb power bank(I can plug in 2 power banks if necessary). To conclude, I have to fin a solution to heat approximately 1.5L,( but most of it is filled with air), at 60°C, with a power of a maximum of 20W. I saw things to heat coffee by USB, would it work if I take the heating pad? Also, I would like to know how much power I can  get from a power bank (in W), before it to heat too much.

USB power? Answered

I have a 1.2 V nimh battery and a 3.7V li ion (no protection circuitry) battery, which would add up to 4.9V if put in series. However, I want to turn it into a temporary USB power supply (5V) so ignoring all the things regarding putting 2 batteries of different capacities together, is there a way to kick the voltage up a tiny bit? I was thinking something like filtering the output of a joule thief, possibly. I also have a solar panel (4.5V, ???A) and was wondering if that could help, but I don't want to rely on it too much.

USB Spacebar?

So Im not sure this is the right place to post. But please bear with me and forgive me if its the wrong place. Thanks! (Oh, and sorry this message is so long. I wanted to be extra thorough. :))Hi,My names Emily and Im in a band. Were a three piece: weve got a keyboardist, guitar/vocals (me), and a drummer. On the 28th we have a Battle of the Bands where were playing 4 songs. One of them, a new one, has just recently been recorded/mixed. On the recording, where weve worked very hard on getting it to sound very good, theres a sort of sparkly background melody thats going on behind the normal parts that was added in the mix. Since then, weve grown very attached to these sparkly noises. However, everyone has their hands full (quite literally) and cannot play the sparkly noises at the same time. We had to find a way to automate the noises playing.So, today we had a practice and we decided to try to get these sparkly things going. We did find a very unorthodox, time consuming and temporary way after a lot of time wasting. Our way of getting it to work involved getting a separate laptop, plugging it into the PA (the speakers, that is, for those who are less learned in audio), attaching a USB keyboard to the laptop, make a loop in the best way we could of the sparkly noise, and leaving the screen open so that the keyboardist could with his toe hit the spacebar to make the sparkly melody play. This method had a couple disadvantages:1) We simply cannot continue to use this USB keyboard. We only have one USB keyboard in my house, and its used on a computer that has no PS/2 ports. So I had to put it back today, and we just need another solution.2) The keyboardist kept accidentally hitting other buttons/the mouse pad when we used the built in laptop spacebar, making the automation stop, pulling up some weird program, etc. This was why we switched to the USB keyboard. However, he still occasionally hit the wrong button, caused problems, etc. We could, in theory remove all the buttons except for the spacebar on the keyboard, but like I said, I have to return the keyboard and I dont want to ruin anything.3) A KEYBOARD IS BULKY, can break, and looks weird on stage. We have a complicated enough set up already and this simply adds to the issue. I have no problem using an extra laptop, but the keyboard has to go!The solution:This is where you come in! My hope was to try to rig up a modified staples easy button, a keyboards sustain pedal, a Rock Band (the game) pedal, etc. (any sort of pedal) and just make it so that you just plug in the device and you have an assignable button. (In this case, a spacebar.)Im on a tight budget.Any ideas?PS: If youd like to hear the effect/song Im talking about, please go to www.power-pirate.com (my bands website), go to Music, listen to the “In Mind (DEMO)” mix. Feel free to skip to the chorus, the part Im talking about starts at 1:04.PPS: When I posted this text into the message body box, all my apostrophes turned into weird special characters! So yes, I do know basic grammar, but my computer doesn't. Sorry about that :p

Back USB Ports Not Recognizing USB Drive

I recently (2 hours ago) made a case for USB drive because the case "broke" off. Anyway, my main USB ports on the front are on the bottom, with a stiff port cover over them. This makes it virtually impossible to use my USB drive now, as I cannot fit it in the tight space. So I want to use one of my 4 ports on the back. My problem is that when I plug the USB drive in, it just will not recognize it. I tried it it in my mouse port, keyboard port, everything. I tried it with another USB drive to make sure I just didn't ruin my first one; it wouldn't recognize it either. Maybe I'm missing something, or being ignorant, but I can't seem to figure out why it won't recognize it, and what can be done about it. Is there some menu like in the Control Panel (though I checked) that enables the ports, or what? I really to have to go case-less. Thanks! Edit - I'm running Windows XP Home.
