How do I build a microphone preamp for a Macbook Pro? [more inside]

I have a medium-sized run of printed circuit boards that'd be most cost-effective for me to silkscreen/photo-etch at home. I'm pretty sure I got that part covered... lots of tutorials available [1, 2, 3, etc]. It'd be a shame, though, to build this setup and then not use it again, so I'm wondering where are some great repositories for (all types of) PCB layouts? Added difficulty: Would like reasonable descriptions of "what they do" and how the boards are likely to be employed. [more inside]

Should I eat – er, solder – this? I'm building a preamp and I just discovered that I'm low on 0.1μF 50v ceramic disc capacitors. My question is about whether it's worth trying to salvage more from another (already disassembled) piece of equipment. [more inside]

Electronics filter: What can I do to make a 24v PSU turn into a 18-19v PSU? It's 0.5A power supply which as far as I can tell is important to know when using, say a resistor to lower voltage. But how resistant should the resistor be? I've found information on how to tell a resistor's value, but not how it will actually effect a line's voltage or how to calculate it. Are there any good sites with this information? Also what will happen to the amount of amps the PSU supplies when I do change it to 18/19v?? Also, what can be done to increase the amperage of a power supply? What inside the circutry is actually dictating the amperage?
