    Switch-mode Nicad charger failure

    Hi Mooncat, Is it dead or does the discharge part still work? Do you have a schematic to post? Some pictures of the internals perhaps? Have you checked for fuses (might be soldered to the PCB)? Have you measured the temp switch inside the battery for open circuit?

    Hi Jim, So, we are talking battery powered and spark free!? ;D I suggest a CD4060, LEDs, a piezo beeper a three way switch and a few small parts in a sealed box.

    Well, I would go to the store where I bought it and tell them to put it where the sun doesn’t shine, because that’s where the crap should be! Then I’d find me a quality player at another store!  8)

    efficient 12v to 5v regulator chip.

    If I got it right here you need less than 500mA and this should be fine with almost no heatsink at all. If you fit it in a metal box just bolt it to the box and you’ll be fine. The tab of the MXL1074CT-SL is common ground so you don’t need any insulation for it if you don’t want to. (I presume...

    Hi Jordan, There are two possibilities here; one is that this is a crappy player (I have seen others also struggling with diverse problems with this model). Second; the installation is poorly done (unless the car harness has some flaw)!

    efficient 12v to 5v regulator chip.

    Woops!  :-[ The MXL1074CT-SL is available as sample and works the same way as the MAX724-26 (max 2A).  ;)

    power supply failure alarm

    If a power supply fails you either lose the power or getting the wrong voltage. The need for failure alarm or a backup system depends very much on the use. A life support system needs a backup but for a less important power supply it might be enough with a failure alarm.

    Hi Jim, Welcome to our forum. You have to reveal a little more about your invention so we are able to help you! What I mean is we need to know something about the voltages and how much power (Watts) you like to control.

    efficient 12v to 5v regulator chip.

    Here is another possible solution: http://datasheets.maxim-ic.com/en/ds/MAX724-MAX726.pdf High current, high efficiency, no heatsink, low part count, free samples and no fuzz! ;)
