It looks great.  How did you cut the letters in the acrylic?

Did you cut them yourself and if you did, what method did you use to do such a nice job.

Nice, I will now make one

Off to the laser cutter I go!

Yeah sure...

Once I get my website up and running then I may sell fronts for them

I am not starting the project yet, got rather a lot of other stuff to do currently.

Who else would be interested in a laser cut front for one?

Mowcius

Price will depend on the size, I will get back to you on that, probably about £20 (currently about $30 USD) for a square, with mounting holes and all letters laser cut, about 8" sq (21cm for you metric guys )

No, I would not do it with vinyl sticker like the copy one is done. I would laser cut the letters into 3mm acrylic and then you would just light up behind each word.

There may be a problem with that code because it updates the time using a timer interrupt and if this occurs in the middle of your displaytime routine, the relationship between hours, minutes and seconds can  be broken.  You can fix this by disabling interrupts when accessing the time variables that can be changed in your interrupt handler. But why not replace your interrupt handler with a call to millis().

Something like this code in your loop function:

Code:

unsigned long prevMillis;

void loop() {
  while( millis() - prevMillis >= 1000){
    prevMillis += 1000;
    ss++;
    if (ss==60) {
	ss=0;
	mm++;
	if (mm==60) {
	  mm=0;
	  hh++;
	  if (hh==24)
	    hh=0;
	}
    }
  }
  // rest of loop code here...
}
