Hi Mike,
Wiring diagram on page 19 seems to be still showing a 1000 ohm resistor, though that could be my poor, sad eyes.
Page 30 the parts list calls for 220 ohm resistors, but text and wiring diagram indicate 150 ohm.
Am I correct to assume that wherever an LED connects directly there should be a 150 ohm resistor? Or are there some LED's that require a different size resistor?
By the way, the only reason I'm finding these potential problems is because you've created a document that's fun to read!
Thanks again,
Mark
