    pcb software

    Hi Bjorn, I use Eagle sometimes but Proteus most of the time; Proteus is nice for simulation and drawing schematics. My projects tend to be made on strip board! ;D

    19v 5A PSu

    Hi Xenobius, It’s not easy to design a SMPSU, are you sure you don’t want to try to repair the old one first? About the motor; is it suppose to run in one direction only or must it reverse too?

    high voltage photo flash capacitor charger

    Hi Steven, Do you collect capacitors? ;D You can charge those caps (first pic) directly from mains via a rectifier bridge to about 340VDC. Your mains power is 240AC, right? Maybe you should use a resistor is series not to pop your circuit breakers or fuses! Be careful, these caps can kill you...

    peavey pv-8.5c

    Hi fellow, I agree, the quality is not perfect. I can read the parts list but some of the small print on the schematics is not clear. For trouble shooting it could be good enough, however it depends on what you need. With the help of the part list and some imagination it is possible to identify...

    12V / 5A Transistor Switch

    Hi Guys, As I mentioned before ripple can be fatal to the clutch especially if the driven load requires near maximum torque! A “clean” DC voltage will prevent a slipping clutch! 8)

    SIM CARD READER

    You can take a look at the TDA8003TS and it’s data sheet, maybe it will help you. The data sheet: http://www.semiconductors.philips.com/acrobat_download/datasheets/TDA8003TS_3.pdf More info : http://www.onsemi.com/pub/Collateral/NCN4555.PDF...

    12V / 5A Transistor Switch

    Hi Kain, Ok, sorry if I was a bit drastic there but the idea was not feasible as I see it. I think you need a transformer or a clutch made for 120Volts, those are the two possible ways. A more complicated way is to use PWM, it is done in some contactor circuits where 24V contactors are run...
