    Help for power supply.

    Hi moutoulos, Before this circuit was changed (from the original by WA0AUQ), it had a 18Volt transformer and it was intended for a fixed 13.8V output. It would work fine this way! This is the original:

    Choice of switching regulator IC

    Hi autir, You could go for a primary switched PSU, no heavy transformer, small size, high efficiency, very small heatsink and heat loss! What more could you ask for? ;D

    basics of electrical supply

    Why is it called “live” when it easily can cause the opposite?  ;D

    Sure! On a day with your stupid hat on, anything is possible! ;D ;D

    Need help building off this schematic.

    Hi Lou, I suspect this circuit is supposed to be used to adjust the voltage for a CPU? In that case do you know what kinds of PSUs are used in every computer?? 8)

    led lamp

    Well, when you put it that way I can almost agree on the transistor even though a common BC635 would probably work fine (not tested though). However the ferrite core, I could find some in my junkbox or easily buy one in an electronics store. ;D

    Hi Audioguru, Why is the transistor and core so special, please enlighten me?

    Need help building off this schematic.

    Hi Jordan, Are you aware of the amount of heat this will produce? Maybe a switch mode supply is better for this purpose?

    This might explain a few things, or it might not! ;D [attachment deleted by admin]

    Hi Guys, Here is a simpler approach to solve this problem: http://elm-chan.org/works/led2/report.html Or like this: http://elm-chan.org/works/led1/report_e.html ;D

    TTL Buffer

    Hi kabilan, MP, Well, it is pretty safe but to be absolutely sure there is only the galvanic separation which will allow 100% safety. On the other hand, if you know what you’re doing you don’t need it. Just double-check everything before you start things up and you’ll be fine. ;D

    An Open source , CAN-bus based automotive wiring harness for the masses

    Hi cgriffin, As I said before, an interesting project which I like to follow. I am afraid I can’t help you much at least not at this point but please keep us posted with details along the way and maybe we can fill in some blanks for you! 8)

    Inverter Circuit 12V DC to 230VAC Sine Wave

    Hi Audioguru, Yes you are correct, there are twice the number or more of the N type around but the Rds and the price does not differ that much. However I agree, N-channel would be a better choice for this inverter. I bet they came from his junkbox !  ;)

    lots of new circuits

    Hi Dazza, So that’s what the nails are for, I thought they where there to prevent things falling of the globe down under! ;D

    TTL Buffer

    Hi kabilan, Welcome to our forum, These buffers will not galvanic separate the computer from possible damage, only opto couplers or relays will do this.

    help in field of radar

    Hi mrsandeep, Welcome to our forum. I don’t have any small radar project for you but here are some links about radar. I am not sure what level you are on so these links are a wide variety on the subject, I hope that at least some of them will be helpful. ;)...
