Second Attempt Prototype

This time around I went ahead and used a laser cutter to cut the intricate shapes. I also added all other animals to the mix and slimmed down the model (2.5″ tall).

Each LED has a separate bracket inside to focus the light.
I implemented 2 buttons to fade in on special characters using PWM and added an ALL on function.
So~ what did I learn:

* USE HIGH FLUX LEDs, ~ wider spread but still direct light.
* Use thin paper so there is less distortion around the edges of the cut shape
  when light passes through the hole space
* Wire wrap is awesome but gets really tedious after about 6, is there a better
  solution?  I don’t know yet.


code is available – send me an email – I’d like to take keep the site
as uncluttered as possible =)
