Here's a thingy that I've been fooling around with for a while. It's a 74HC14 TriCORE that gives you some interesting results. The caps are .22uF and the resistors are 1M. You can get three basic states from this configuration. 1,0,0; 1,1,0; and a really neat 1,1,1. I drew the schematic like this for artistic value alone. No other reason than that. |
