    Combining Micro Generators

    As dc generators will also run as motors, you'll need to "steer" the output of each through a diode to your battery. As the least amount of voltage loss would, I imagine, be desirable, use schottky diodes as these will have only 0.2v loss as opposed to a silicon diode at 0.7v.

    Original way to use car radio as a garage radio

    AM radios were mono , not stereo. May have been front and back but mono just the same. Some even had the speaker built in to the radio.

    Modified sinewave to pretty good sinewave?

    Your problem is you apparently look up Google for a few technical terms and then redistribute them in your answers here without any understanding of what is the theory behind the process.

    Original way to use car radio as a garage radio

    Simple to put on a 2 way switch, charge when not in use. No problem with excess voltage, car alternators do it every day.

    Panasonic stereo no power

    I'd say you didn't even look at this before you posted it. Reason is.....no schematic. Try again.

    Suggestions for winter electronics projects wanted

    Just about everyone would have made one of those 555 keyboard organs at some time but with "pcb piano keys" and an old biro as a stylus. Great stuff for kids though. The vibrating robot is something else again, great imagination. Good choices I think. Same thing for us here...we are finally...

    Malfunctioning Popcorn Machine (burning resistor issue)

    Lets see if the penny drops......... Brown black black gold on original is 10 ohm....... (10r) ... (1 x 10r) Your arrangement is 4 series 1k resistors (4 x 1k0) ....total 4k0 or to make it clearer 4,000r or 4,000 ohm (thats four thousand ohm)

    Modified sinewave to pretty good sinewave?

    Proof of the pudding as they say, is usually in the eating. Now include inefficiency. BTW...don't forget the inevitable run down in cell characteristics.....

    Actually it's 746 if you want to be picky.....

    Malfunctioning Popcorn Machine (burning resistor issue)

    1 x 10 or 20r is not equal to 4 x 1k in series or 4kOhm.

    What transter starts a kawasaki nijah what dose it look like

    Some early model Kawasaki 750's had an accessible ignition control pcb and replacable discrete devices.(non-potted) Found that when my mates kids re-connected his battery in backwards after pinching it for their machine. Black box at the time was around 200.00 and I replaced the blown output...

    Subwoofer repair

    As above, my thoughts were that cost would have been in the mind of your techie...... Sometimes, as I once found with a Panasonic unit, even DIY with considerable knowledge is a waste of time. Much easier, quicker, cheaper to source a second hand working unit online.
