    n64 analog stick help

    You may have better luck with a PC joystick (like the actual joystick part), but I don't know how big you want it to be.... Then again I would imagine a lot of this kind of stuff is probably done with the photo-interrupters... I know they are pretty small, which seems to be the goal a lot of...

    5v to illuminated switch - help

    I gotta say, it looks excellent, I like the breaking it into 2 parts thing as well! keep up the good work! Oh, and the DVM is a VERY nice touch, I have a few atx supplies kickin around, I may very well do that after I get my scope off my bench (that is... still workin on it!)

    Anyone with solar panels on their roof?

    Considered it for my parents house actually... decent orientation, but due to the climate up here, the pay off would take a fair amount of time (I was thinking somewhere in the 20 year range)... and the roof would probably need serious repair before then (due to the age of the house). Though I...

    Broadband fm transmitter

    Quite a nifty technology, I've heard it called several things but most generically, Cell Broadcast.... Last I heard they were trying to get something like that going in the US for amber alerts and such of the like.... I think it would be great, but it seems that no one wants to cooperate or has...

    merging 2 circuits - speakers with external power and an ipod dock

    Welcome! My first thoughts of the issue that you are having, you have two different signal levels... the speakers you cut out were one, and the RCA (red/white) are at another. One thing I would try, is to get the audio signal before it hits any part of an amplifier... line level is what you...

    Samsung HP-R5052 plasma won't start

    There is a lot that I would like to say to this, so I will keep it as brief and professional as possible. 1. "True" obviously wants to do this, and is not afraid of breaking his Plasma or none of us would be having this conversation. FRANKLY, I would say that as long as the person understands...

    Samsung HP-R5052 plasma won't start

    Sorry. I don't know if it was that way by design or not... but I do know it was performing at least some of the function it was supposed to... as far as I can tell, it was still operating normally. Granted, some of the things I have seen have been broken, thus, I replaced the component. I...

    Samsung HP-R5052 plasma won't start

    I hate thru-hole stuff... I have learned a couple of decent removal techniques.... but I can't tell you how many times I have done more damage by bad de-soldering... now I am a bit on the brighter side. I agree with seasonedtech on this one, it looks like it could be compromised. To answer...

    Samsung HP-R5052 plasma won't start

    I gotta say, not a bad looking job you did there.... good luck! Normally I just replace those... it almost looks like an IDE (computer 40-80 wire ribbon... 28-30ga wires) cable.... which, again, I just replace. Honestly though, considering the size, I think you did a pretty decent job, but even...

    Just a quick little link for ya, I am actually going to be doing a similar amp.... only for my Bass guitar... so a little Capacitor modification is necessary, but this site you may find very helpful. http://tangentsoft.net/audio/cmoy-tutorial/ Matty-

    14-pin ATX Power Supply pinout

    Both the ground leads (should be all of them) and the case should be grounded to the same ground, you can make sure of this with a continuity test or a basic resistance test, you should be getting VERY low resistance (if any) when ground leads are tested against case... there is probably even a...

    Fm transmitter question

    So I know this may sound odd.... but i still prefer wired to wireless... but thats because I can hear the differences not many others can/care about. If you wanted to do wireless, there are systems out there that basically plug into your computer (or any audio source)... transmit on something...

    14-pin ATX Power Supply pinout

    Agreed with Steve, all of the rails in your power supply should be linked together.

    Laptop LED screen issue

    Never heard of that brand before no... However it seems like you have a pretty good idea what's goin on. I would say you are probably correct with the fault being the actual screen. (at least at this stage) I would go with what rob was saying, tape something small to the end of your probes...

    Laptop miniDIMM 144 pin 0.5mm connector supplier?

    I know this post is old... but what kind of a laptop is it out of? What is the port on the laptop called (sometimes you can find it that way)... for example, HP has a wierd one: High speed serial port (sometimes called), its on the side of a lot of hp laptops, it generally connects a dock.

    CAR ECU HOW IT WORKS

    Depends on the car, most modern cars... no. Not one way that I am aware of... most of the keys now have a "transponder" (RFID Chip) that the car needs to see before it will start... or stay running. This security measure should not be bypassed, not only could you possibly completely disable your...

    Looking for ECU circuit diagrams ...

    I used to have some old Saab ones (like pre-1994), but thats about it... and honestly, they were kinda hard to read (partly in Swedish, and the quality of the PDF was not fantastic). In general though... yeah its hard to find, due to the proprietary nature.

    Tektronix 475A Display problem [Horizontal?]

    Okay, just ran through all of the power supply test points, pointed out by my service manual... the 50V line was at 49.6, so I adjusted it back up to 50. I double checked it with both of my meters (analog and digital) and both meters agreed it was a little low.... double checked after my work...

    Yet Another Voltage Regulator Thread

    Under powering varies a bit, I've had an LED that was just kinda dim, where as others, it just simply didn't work.... I have heard of people prematurely frying them... but I don't know if its true (I would expect that it could be...). Globs of solder will always still work! it may just look a...
