Re: Interest in Knock LEDs?
I needed to order some electronics for some PC projects, so I also ordered some 4049's for this. That's one step closer than I've gotten before. =)
I found a simple inverter circuit that should work for this in place of the 4049. It's just a transistor and two resistors, so you should be able to pick the stuff up at Radio Shack. However, the 4049 is quite cheap, and should be a smaller package than trying to solder up the parts (i.e. not doing a SMD board or anything like that). I added a link for it on my Knock LED page.
