    Hi toXic, Welcome to this forum. Can you explain in more detail what you want to do? What kind of object do you want to sense, is it metal or plastic what shape? The more details you supply the better solution you can get. Pictures will help.

    Reduce output Voltage of Power Supply

    Hi Audioguru, Nice bargain 3 to 36VDC switcher for 2 bucks! :o I wonder if you can get 2A over the entire range though? If you can, congratulations to a very nice PSU! Normally switcher like these for laptops and such do not have that big range maybe 14 to 21 volts or so but with a schematic...

    You need an Schmitt trigger circuit to have a more distinct off and on here. Unless you are satisfied with a poor circuit and poor over all efficiency.

    Transformer ratings?

    Hi Audioguru, Sorry to step in like this but I think Rhonn has 230VAC in his outlets! So 125V is no problemo . ;D ;D ;D

    lm741 schematic diagram

    Kevin, On the first page of this datasheet http://www.ensc.sfu.ca/reference/data-sheets/LM741.PDF you can see exactly how the 741 is built inside.

    Reduce output Voltage of Power Supply

    Hi Robert, Everything that Lou said makes perfectly sense. But if you are not sure what you are doing, please be careful. A PSU like this has capacitors inside which has several hundred volts perhaps for minutes after you have disconnected it! :o Can you try to get schematics for it and we...

    Changing 12v to 24v with out a transformer

    Kevin, this is an audio amplifier IC http://www.tde.lth.se/ugradcourses/elektronik/pdf/2004.pdf not an op-amp. The diodes are Schottky diodes that are fast and have a low voltage drop.

    Wait a minute! The phototransistor can only withstand a maximum current of 20mA. If the 2N3055 have a gain of 20 this means the collector current cannot exceed 400mA or the phototransistor is history! Just a caution!

    my project

    Hi Joe, Welcome to this forum. I think what you mean is a light organ. If this is the case I might have some schematic on such a device. Are you into electronics or is this a first project?

    lightbulb's role in car amp

    Hi Matthew, A circuit with the same characteristics as a cheap bulb would be complicated. Low voltage bulbs are not as sensitive to vibrations and shock as mains voltage bulbs (lamps). A workshop safety hand lamp with a 24Volt bulb can be quite violently handled before its filament burns off...

    Sound activated NE-2

    Tubby, What kind of AM transmitter do you use? Is it a tube circuit them maybe you can tap voltage via a transformer from the anode side to a neon bulb.
