Re: White LED strobe
What might work is a 3909 IC. It can fire a LED from 1.5 vlots Vcc. I think it works in charge pump configuration, firing the LED from a cap.

Re: Scavenging old electronic equipment
I have found that Conair answering machines have a LOT of diodes, caps, transistors, inside. Now these are the ones that dont use tapes. I'v been finding them for 2 to 4 buks at DAV or Salv. Army stores.
