  1. Can anyone explain to me the function of an op-amp in a simple manner ? Especially this IC > LM358N http://rocky.digikey.com/WebLib/ST%20Micro/Web%20Data/LM158_258_358_A.pdf
  2. Hey Audioguru i made in 3 days time the original circuit in Express PCB. Anyone has got the skills to make it match with the modified parts ?? PSU_0-30V_0-3A.zip
  3. I have requested some parts from NT. At first my 1st mail at hotmail required that i pay because they had too many req from that email provider. After that i put my other mail, but someone after 2 days reported that they couldn't give me samples. ANd all these because i am wrote no company i just put student.. I had requested 5 X 3914LM.
  4. Hi all 1st post here And to start quickly here are some questions... 1) On post #93 someone asked about higher Voltage rating Caps can be used (change a 50V to a 250V) but he went to sleep :P So is it possible ? The voltage rating of caps refers to how quickly does the Cap releases its energy ? 2) IS there an updated PCB image yet ? 3) In a previous post you audioguru say "Our project doesn't specify a part number for D6" But i see on the project page that says D6=1N4148 In the end shall we use the BZY79C5V6 you suggest ? Or you did a typo, and you meant changing D7 and D8 ??
