[sdiy] PC-based synth advice

[John L Marshall]

The main board is also noisy. Consider all of the digital logic on board with nasty rectangular waves. I prefer to put the analog stuff outside with a separate power supply. The fan cools the power supply and the rest of the computer as well. If the power supply is 80% efficient then 20% heat is generated by the power supply and 80% heat is generated by the rest of the circuitry.

Have you considered building up a lunch box computer? The LCD is built in. The keyboard protects the LCD while traveling. Standard size peripheral cards (PCI) and drives (3.5") can be plugged in. You may not need an SVGA monitor in the studio.

  Hi all,
  I'm working on a PC based synth: I use a single-board PC with some components: HD, FDD,DACs and of course a power supply; all this placed into a aluminium box.
  I would like to use my system in two situation: studio, where I will use the VGA output and a monitor and stage where I'd like to use simple LCD. Here is the problem: I can find LCD displays (in Italy) only at a cost twice than US and other countries. My question is the following: Does someone knows some place where I can buy a LCD display (2 * 40 characters could be enought) for a reasonable preice ?(possibly in Europe, so the delivery cost will be low) A 40*2 display cost me about 60$.
  P.S. I someone has already build a system like mine (as I seen by some mails) or has some idea, I'd like to have some advice. For example: the PC power supply is quite noisy, I'd like to place it in another box, is this a good idea?
  Thank you.
  Stefano Chiappa
