    PROBLEms of LM317

    After decoding this: I gathered you want to know about the following: Yes IC1 is the current limit part. The current limit does prevent short circuiting. You can find a complete explanation here: http://www3.telus.net/chemelec/Projects/Power-Supply/Power-Supply.htm

    Simple O2 meter with LM3915

    Hi gearhead, They are printable, only adjust the size if necessary to fit your printer! I am sure you know the 2.54 mm (or one tenth of an inch) distance between the IC pins, use it as a reference!

    Need drawing for Toshiba V-75TR

    Hi tufail, Welcome to our forum. Sorry I do not have any schematic for you but these PSUs have problems with bad caps, so I believe that’s what you should check first. I hope this helps.  ;)

    circuit converse High voltage AC to DC

    Hi Mike, Believe me, I was laughing during the last post! ;D You haven’t appeared like you where stupid before so I guessed where you where going with it. It was an obvious worst case scenario of curse! :D BTW, could we be sure that 1000 of the 50V diodes would survive 50kV? Will the voltage...

    circuit converse High voltage AC to DC

    Hi Mike, Why use the 1N4001 (50Volts) instead of the 1N4007 (1000Volts) if you must use diodes from this family? ;D Why not use diodes for 32kVolts, not that many will be required? ;)

    circuit converse High voltage AC to DC

    What’s the source of the 50kVAC and what’s the power (current)?

    circuit converse High voltage AC to DC

    Hi nametc3, Welcome to our forum. The way to convert 50kVAC to DC is easy; just use an high-voltage rectifier!

    battery and HDD

    Hi atoof, OK, that’s fine! Use an LM78S12 to get 2A for the drive motor and you’ll be fine!

    battery and HDD

    Hi atef, The question is; are the four IDE ground pins connected to the negative of the power connector onboard the HDD or not? On the motherboard they are connected but this does not help if the HDD gets its power from another source.

    alternator

    Hi anton, The alternator does not produce more current than the circuit consumes at the regulators pre-set voltage!

    battery and HDD

    Hi atoof, If the HDD is an IDE type the IDE bus needs to have common ground with the motherboard or the two floating grounds can obtain a destructive voltage between them. This means there is no protection against static or some stray voltages. My guess is the IDE controller circuit in the HDD...

    free energy motor

    Hi indulis, Yes, I agree the methods are probably the difference here not the copper. I haven’t gone deep at all into this but from what I have read things have been learned from optical fiber signaling even though these are conducting light.
