    Electromagnetic sensor

    Hi!!! the website you posted is all about the experement on how the brain scanner operates... Maybe the uses of that is working out radio signal in a path to locate cancer and it is the basic part of the human technology...maybe anything will do...but for now there is nothing yet to have a...

    Looking for circuits about stealing energy from energymeter

    stealing energy Hi!!! Maybe such energy meter is Ammeter!! because it uses an energy transfer from current flowing to the wire and it trasfer trough its core for the neddle to deflect.. so if done this the energy transfer is involve by this you can make another inverter using the basic...

    battery charger: buck

    Hi!! try to put a line filter using a coil. Put the said coil in the power line or connect it in series in Line1 and line2 of your power line. Use #20 magnetic wire with more or less 20 turn and fashion loop to the firrite core. If the problem could not be fix try to add your filter capacitor or...

    Overvoltage and Undervoltage

    Actually the overvoltage is depend upon the load.. Too much loads will create this because the the loads consume much current and the resulting to decreasing its voltage... it is the voltage resistance and current relationship.... more loads more current is require and the resistance of the wire...

    Need Help : Inductor & capacitor design for the boost co

    If that so you need to design the step up transformer for you to make the 325 v of power... because the inductor and a capacitor cannot do it because it is mainly a power filter.... If so use the rectifier diode with high breakdown voltage but the problem of this is you cannot control the...

    Help me with noise caused by power supply

    Noise problem Hi..!!! Try to figure it out... your power supply is too noisy but we have to know what is the real score or what is the load of that power supply... If your power supply is too small than the load of course it will create a noise like it is vibrating.. If your Transformer core is...

    comparing opamp design wrt BJT vs Cmos

    If you mean about the advantae and the disadvantage there are so many thing here to rememder opamps if you use to say is the most basic design used for a long time, now this opamps is simply say, it is a transistors circuit design used in so many variety of appliances and it make the electronics...

    DC-DC converter problem

    usually the better understand for this is the driver of the high side is from the +vcc to the load or it boost the b+ to improve its power but decrease its current maybe or better you have to use a high current dc to dc output transistor and in the high side is the Load is connected directly to...
