A realisation

By using the internal oscillator and not an external crystal as I have been doing until now, I free up 2 extra pins on the microcontroller. This means that I can drive four RGB LEDs with a single 16F628A! (OK, five if I didn't need to interface with an EEPROM and have a button.)
Old news for pretty much anyone who has ever worked with these things, but I just tested it out yesterday. At heart, I'm still a n00b.

Also, the DCF77 receivers arrived! Now I can start building binary LED clocks that get their time off the atomic clock in Frankfurt!
