    Pump protection circuit

    Hi Steve, The current sensing could be kept simple by using a low value resistor in series with the pump motor wiring. Some experimenting will reveal suitable threshold values (voltage drop) where to switch the pumps off and on. You probably need to make some delays (analogue or digital) for...

    Plessey ZN416E AM Receiver

    The ZN414Z and the ZN416E has been obsolete since at least the early nineties! You will be very lucky to find one of those! I believe the only chance you

    very simple PS

    Hi Guys, Perhaps it should be mentioned that the forward drop is actually 0.8V at 200mA (like in this app) and increasing to 1.1Volts at 1A. AG; What happened to $crooge?

    New here, problem with a certain part..

    Hi fuz, I believe that is the power input filter you are referring to? It is actually two parallel inductors with a common core. Perhaps this type might be used for signal inputs too. Parts from EPCOS shouldn

    Pump protection circuit

    Hi Steve, I think we need to know more details to give you a more precise circuit. From what you give us I would sense the decreasing current to switch over to the second pump and if required even shut the second one down when it runs dry.

    52" RCA big screen - no power Service Manual Needed

    Hi John, I suppose the problem is the projector is missing one color? Are the tubes leaking?

    Momentary switch

    A 4-way which looks just like a standard toggle on top is not easy. Unless you could see some markings to identify an old one its hard to find. Here are a few examples to look at. This is a (normal) small one: http://www.etisystems.com/j1.asp Here is a really small one...

    Hall effect sensor bypassing?

    Most likely this is a switching sensor not a linear one!  Sensonic?

    Hi Doc, I agree, this is an absolute goldmine, if you know Russian! I browsed trough the books and magazines to find a bunch of EPE magazine in English but nothing else! I found many interesting books but in Russian which is too bad! Perhaps I need help to navigate to the 80% of the titles...

    inverter

    My car has a 1.7kW alternator but I am sure you could find larger than that so I don’t think there would be any problems. At least not at engine rpms greater than 3000!

    infrared help

    I don’t believe it’s possible to change the wavelength and the problem is most likely that these are to narrow banded to communicate. Try to hook up a scope to see if there are any changes in voltage at all.

    12vdc heating element

    You need to have the oil inside the injectors heated too, or the engine won’t start! The system described by Ldanielrosa will work fine but do not forget to switch over to diesel again some time before you stop the engine!
