    Kris, I'm often impressed with the quality of your contributions on the forum but this one strikes me as amazingly comprehensive.

    Can some one tell me what exactly is this and where I can found it

    The schematic confirms what I previously stated. The board appears to have been damaged by contact with liquid. If so, it is probably unrepairable as the inner layers of the board may be corroded.

    Can some one tell me what exactly is this and where I can found it

    47 µF, 10V tantalum capacitor; size unknown; available from Digikey, Mouser, etc.

    Buying resistors; better just to get 1 Watts?

    Another consideration is that ¼W resistors are the largest that can be placed side by side on a standard 0.1" (2.54mm) spaced breadboard or prototyping PCB without interference.

    Last night...

    You guys (Kris & Chris) have musical tastes that overlap much of mine; I have all of the Alan Parsons works, etc. so you might like to see a YouTube playlist of stuff I've been listening to over the past year or two as my musical horizons have continued to broaden. KJ6EAD channel (Excellent...

    LED on AC Mains

    I often refer to them derisively as "destructables". Better methods for powering small DC loads from AC main voltage without a transformer are shown here: http://ww1.microchip.com/downloads/en/appnotes/00954a.pdf http://www.zen22142.zen.co.uk/Circuits/Power/tps.htm

    Happ switch Illuminated button help

    You can do better on the technical specifications but it won't matter since you can't control the 12V for the LED and a 5V signal with a single pole switch simultaneously. You could exchange the switch to a double pole model but that's not an ideal solution either. http://na.suzohapp.com/

    Help identifying component

    They're Molex series KK connectors with a 0.156" pitch available from all the usual electronics suppliers and from arcade and pinball game specialists. http://www.molex.com/catalog/web_catalog/pdfs/D.pdf

    Overloading an output , blows transistors why?

    You may be getting confused by semantics. An overload is not an increase in resistance to current flow, just the opposite. It might be better to call it an overcurrent condition, but terminology develops in illogical ways.

    Happ switch Illuminated button help

    First; supply the specifications from Happ Controls for the switch and LED. I'm guessing the LED has a built-in resistor for 12V but give us the spec's. Second; what, if anything is the switch controlling; just the LED or what? Third; what's an iPac and what connection are you making to it...

    I wouldn't be that stupid! (would I?)

    Leaving aside the fact that only amateurish misuse of the meter could result in the need for a fuse replacement, I would have pulled the ferrules off of the glass tube and mounted the SMD fuse inside with bus wire soldered to each ferrule producing a finely crafted kludge fuse. ;)

    New to the board, need help identifying a plug

    Often, there will be a manufacturer's logo and/or model series identifier molded onto one end of the shell.
