I have an interesting idea, does anyone know if there is a device/control unit that can send a 12V DC signal on command from a a serial port? If i wanted to control strobe lights or neon from my PC? not outputing the power from the PC but using the PC to "flip the switch"?
www.discolitez.com--try it. Also I've been researching using Natnl semi's LM3915 chip to build a five band spectrum analyser LED display. That might help you as well.
you can also use your serial out only. DTR and RTS can be used to trip a low voltage relay. So you can control 2 items with one serial port. You can also use your LPT but I have not played with that at all.

OMG, you so deserve to be flamed for bringing back a 7 year old topic.

However I think they have moved on, if you can use the USB port rather than serial there is the Fusion Brain, developed and sld by two erstwell members on this forum, plus there is the velleman relay kits. Hell there are loads of relay kits out there, do a search for relay kits.
Using PC to control lighting.
