what are these ic's? Answered

I have puled two components out of an old radio/amp/ cd player etc. and i want to know what they are and if i can use them to make an audio amplifier. one says BC Power Module  SVI 3101 D on the front and 424  1w2  on the back and has 14 legs (it can be seen here, this is actually the exact one i have from the same appliance :  http://farm2.static.flickr.com/1042/4733036801_a2d72f1df9.jpg ) . The other looks kind of like an op amp, it has 12 pins and the part no 5a3920, and below that 218 130a (as you can tell i am not a good at desoldering and not having a solder suck doesn't help).

How to Control a Servo?

How do you control a servo? I know you can control it via Arduino or some other microcontroler, but can you control a servo with out the need of programing??? I know the servo has 3 wires red, black and yellow... and if what I heard is right, that yellow wire is for controlling it.... Thank you! Comodore

How to control a solenoid? Answered

Hi, I have a tiny solenoid from an automatic air freshener that I want to control manually. The solenoid acts as a valve that opens when fed 5v, and closed when no voltage is present. On the factory board, there's a timer that triggers the solenoid every few minutes for a fraction of a second (opens and closes so fast it just sounds like a click). What is the simplest way (No Arduino, Raspberry, etc.) to make a 5 volt pulse to make it go "click" on the push of a button?  Further more, how would I control the length of the 5v pulse?  I want to be able to control the amount of gas it passes (Pun intended) when activated. Any information would be helpful, and a circuit diagram would be greatly appreciated (I can read diagrams but can't design a circuit). Thanks!!!

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!

How to fix a PS3 controller??

So i was playing Skate 2 when I had to go into my kitchen and put away some things. I came back, but forgot I put the controller under the gaming chair when I got up, so I sat, and the chair rolled right over the controller. I looked at it and the left joystick was half out. I pushed it back in and it was weird. It wasn't always in the middle. It would stay up, or left, or upper left, lower right, etc. I pulled the rubber part off and realized that the rod connected to the controller had to go in a slot in the rubber part. But considering the outside of the rubber part have to go INSIDE the controller, and it's hard to do. I tried unscrewing the bottom, but idk what kind of screw it is. I NEED HELP!

How to control the speed of this motor ? Answered

I have this spare Dayton Shaded Pole Motor that I would like to use for a project.  When the motor was removed, just two wires are attached to it to which I attached an adapter plug.  When plugged in to a wall outlet, it obviously runs at only one speed.  I was wondering how I could control the speed of the motor thus enabling me to lower the speed.  Would it be possible to add a dial to lower the speed?   I saw a video on youtube titled How to make a Simple Speed Controller (link: https://www.youtube.com/watch?v=0YZJ0kJEmh0) and was wonder if this would work for my motor? In the video, the guy uses a Switch, project box, and potentiometer.  However, should a rheostat be used instead? (someone posted that in the comments to the video) So, let me know what you think, and how I should go about doing this. Here are the specs of the motor: 1/40 HP 1550 rpm 115V 60 Hz 1.1 Amp Class A Ins, 40 degree C Max. Amb. Cont. Duty Thank you.

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.
