SirPoonga:
That's cool budda.  For me I am going to use the ledwiz as it is usb.  but for others who want to do a knocker that is good info.

Randy just PMed me the led wiz does to 5v per output.  So, those relay's form radioshack should work, I hope.

Just a thought, 3 9V batteries in series would supply 27 VDC.

Not as elegant as a power supply, but cheap and plentiful...

SirPoonga:
Yep, I was involved in that thread.  As I said in many other qbert knocker threads, I don;t want to use the keyboard LEDs because I use those.  I don;t want to use parallel port because I won;t have a parallel port.  USB is the only route and I have been waiting for one of these LED boards to come out.
Quarters:
Anyone ever use one of these with pinmame?
