Now that the design topics have been fixed and the circuit works in simulation, we can continue to generate a layout. Again, using PCBflow will output a preliminary PCB with placed components:
Microcell counts: ne_NOT 21 ne_WAND2 7 ne_TBUF 6 ne_WAND3 2
Component Count pin 8 NE555 21 cap 21 resistor 27 diode 20 npn transistor 6 ------------------ ----- Total: 103
Well, i'd say it's a bit more than a dice with the old role-models of NE555 and CD4017 require, but who are we to judge? Still small enough to comfortably build and test.
Still some work to do manually: Add the LEDs for the dice, add the CD4017 clock generator footprint, add groundplane and let the autoroute do its (admittedly gut-wrenching) job.
And here we are, with a nice simulation of the full PCB. A modern rendition of the classic NE555/CD4017 based electronic dice.
