    What's wrong with circuit?

    John, Others may be able to give a more educated answer but I am assuming the 33nF and 4K7 are the filter (in your 120v version). 15nF and 4K7 in the 240v version I get ( using 1/2*pi*RC) around 2khz and with the original 15nF around 1Khz so I don't really see how it makes much difference...

    KJD 17 wiring to 230vac single cap motor question.

    All of your wiring is incorrect. Can you supply a factory drawing of the motors and their connections.?

    Model Ship LED Project

    I'm in to all sorts of model engineering and have at times used motor winding wire to connect LEDs etc. Fine copper wire with varnish (or similar) insulation. Reason being, one can hide the wire easily by cutting a slot into the wood or whatever. Scrape off insulation with a sharp knife or burn...

    12v Automotive Cooling Fan Indicator Light

    Op says he cannot access the relay ........ Therefore an aux relay on the fan motor.

    Capacitor explosion??

    Sounds to me like the capacitor was rats before the accidental drowning of the plug. Refer ............" The second time I went to start it it would not start. I thought it possibly had something lodged in the impeller. I used a stick to turn the impeller" As for the "explosion", stories like...

    Adding mac mini turn on button to a project(power supply bench diy).?

    First switch looks like a momentry switch (only on as long as you are pressing it) which will not work in your application. I can only assume you need to "turn on" the power supply which you can achieve by simply putting a bridge wire between terminals 15 (black) and 14 (green). Make sure you...

    12v Automotive Cooling Fan Indicator Light

    Leds being small current devices are susceptible to any small feedback giving spurious results if you connect across tha actual fan as you originally explained. What you need to do is as explained, remove the LED from the actual fan load circuit and place in the "control" circuit. This isolates...

    Unmarked Antenna Box - What the Heck is This Thing?

    Sounds plausible. Units like this are usually on a "loan" arrangement. Might pay to check with his doctor.

    12v Automotive Cooling Fan Indicator Light

    Use another small auxiliary relay on the existing fan motor to drive the LED.

    12v Automotive Cooling Fan Indicator Light

    A hand drawn circuit of what you have will get more help. Instead of telling us what you think, show us what you have. Must remember many of the automotive systems are earth return and could present problems to the uninitiated.

    Laser Rust Removal

    Amazing how that bloke way back when first shone light through a ruby, saw the effect and wasn't quite sure what to use it for.

    Pad has been ripped off from my protoboard, now shorted.

    And clean the copper on the board with steel wool or similar before you start. Then keep fingers off.

    Latching touch switch

    Many times see requests here on how to set up a latching switch of one type or another. Saw this at Futurlec and thought it may be of use to some. May have to wait a bit for delivery (usually a bit slow) but for $4.50 I thought it was a steal. http://futurlec.com/Touch_Pad_Latching.shtml

    Lightweight Electronic Spark Ignition for 2 cylinder engine

    That's advance/retard, not fixed ignition. No, not wrong, just a different application. Motor vehicles and the like require the best ignition points to give maximum performence/ efficiency over a wide range of speeds and loads. Not so with the applications I outlined earlier.

    Lightweight Electronic Spark Ignition for 2 cylinder engine

    There are millions of engines out there that use the fixed ignition system. Usual placement of ignition points or whatever is around 28 degrees btdc. Usually they are of a type where a particular rev range is required e.g. water pumps, rotary hoes, timber saws, on and on and no, it's not a...
