iTunes controller?

I'm not sure if I was searching for the right key words, but I was planning on building a desk with all of my computer components built into it, save the monitor keyboard and mouse, and I wanted to make like a little controller for iTunes that controlls random, repeat, next song, previous song, pause, and play. Like, would it be possible to take apart a spare remote control and use the circuitry and buttons from that to do it? Is it even possible? Also, this will be on a Windows 7 PC

But, the lovely people at Microsoft say that it isn't possible to install more than one controller on a PC, but I know that's bull because I've seen people do it before.  I already have one installed; I have the driver and everything. But my computer doesn't even look at the second controller like it exists.  What is wrong, how do I fix it and how can I make gaming easier? Thank you for your time!!

charge controller

Question for you all. I have a solar powered spot light I really like, when it's charged up. It has a 6vdc 4ah battery in it and I wish to re-charge it from my 12vdc system. Source power will be my 12vdc 160 ah battery and I'm thinking of using my extra 12vdc charge controller with a 3.5 ohm / 1 watt (or better) resistor attached to reduce the power to 6vdc. I believe that will work, but I don't know if the controller will know when the battery has reached capacity? The other thought is to just by-pass the 6vdc battery and run the light from the 12vdc system (using the resistor to reduce the power). Any thoughts?

I'm planning on making an Xbox controller with a dualshock 3 controller inside.  I'll be making one for me, but I'm looking to earn some money so I'm curious if anybody would be interested in buying a second one for themselves.  Keep in mind this won't be cheap, it will cost up to $100 in parts alone.  While I don't have a lot of experience, I have a lot of skill (see my tvbgone sonic screwdriver for an example). Lastly, keep in mind this is not a sale yet, just gauging interest so I know whether or to make a second one.  Leave comments here on requests for aesthetic features, and PM me if you have a price you'd be willing to pay.  Please only reply if you're serious.  Expect to see a sale post sometime in July, I'll be going by best offer.

REMOTE CONTROL

Someone can advice me what switch is suitable to use in my remote control. I had tried push button however it does not compatible with the coding (I'm using chipkit UNO32). My intention is to make the user select AUTO mode or MANUAL Mode. After selecting, the user will be asked to select speed and duration. So this requires a lot of loop-inside-a-loop, if-inside-if etc. When I'm using push button, the microcontroller cannot read the command when the second button is push. I heard, if using push button I need electronic relay.

accelerometer controller

Hi I’m making an accelerometer (3-axis) that I want to be able to work in some programs and games. I haven’t built any tech´s before. Hehe so plz replay with easy words. There are some tutorials out there which are based on an old game controller and stuff. But I want to do my on an Arduino board with a USB connection or wireless connection. Here is a tricky part, I want it to fit a cube chassi that is around 7-10 centimeters, I haven’t done it yet so that’s why I put it to 7-10 cm because I have still time to make it bigger or smaller. I don’t know much about the wireless connection and battery to make these things. I know I’m sounding like someone that doesn’t have a clue about these things and it’s true, I want to learn it and make this controller. If someone can tell me more about this sort of project or tips me to a tutorial or something it would be excellent.

Quality control

First, let me just say how much I love Instuctables.com......I really can't remember....not one single time this year, not checking in here for even ONE SINGLE DAY!! It is my go-to place!! That said, I've kinda been thinking about the amounts of digital "clutter" that exist here. Now, I myself have only put up two instructables......so I wouldn't claim to be a MAJOR contributor, by any definition...........but what I mean is....... there are some instrutables here that are just junk!  Some kid zipped in here 4 years ago, put up something he (so-called) "made" with a piece of notebook paper and and a stick......no photos or the photos are garbage, and he hasn't been back since. A few bad ratings, and a couple of bad comments....and that's it.  Has anyone ever discussed any sort of "juried" process after awhile?  I dunno.....maybe it's a bad idea, and god knows my work here isn't Smithsonian quality material, but I did put a'lot of thought into it, and I love the community here! I just think if something has less than two stars after 3 years and all the comments are wretched.......it should maybe be removed. Such an action can be announced, maybe, or voting or something. .....just food for thought. C

Hi, im wanting to build somthing simple to control the heater control valve on my fiesta. its a simple solenoid valve at 0v its open(hot) at 12v(14.4v) its closed(cold) the propper control board uses pulses to control the valve, the board has since given up and im left with a very hot car, now i thought a simple way to sort the problem might be to use the 10k pot on the control board with a MOSFET and just vary the voltage going to the valve. will this have the same effect on the valve?

LED Board Control

Hi there.  I salvaged 2 boards of LEDs from an old LED can at work.  They were previously DMX, and have an array of red, green, and blue LEDs.  There are four leads coming from the board, +, -, a dashed line, and an unmarked line.  I am looking to integrate these with another project, but am unsure how to go about finding how to control them electrically.  I was thinking it might be digitally controlled right on the board, but I see no IC.   All I am looking to do is figure out where voltage needs to be applied in order to have different RGB levels.  If I helps, the number printed on the board is FT140PCB GS.  I am able to attach an image if that would be helpful. Any ideas of how to go about this?  Thanks a lot, anything would help!
