Propeller-Powered Hand Stamper

Within the next few months if you happen to be visiting one of those groovy amusement parks dubbed, "the happiest place on earth" you may -- especially if you have small children -- want to look for the Buzz Lightyear character. Soon he will be carrying a cool hand stamper and it is Propeller powered.

I assisted an engineer at the Anaheim park (where this was created) with the circuit and wrote the code after he built a PCB that would fit in the device. It has been approved and will be deployed to the parks shortly. The program is not terribly difficult; it plays a random WAV file from a uSD card and runs a mini light show. To keep the lights simple and allow the show to be built in DAT tables each output has four levels (off plus three). Each line of light show definition is two longs: one for the light levels (quaternary), the second for timing (in ms). The light show code is very simple and runs in a spin cog, driving a BAM dimmer.

Nope, it's not changing the world but if the sounds and lights of this stamper make one child smile then I am a very happy man.

    Does this stamp with ink?

    I count seven dots. Are these all LEDs? I'd assume so since five and a half of them are lit.

    Are they tri-colored LEDs?

    I'm curious since I recently replaced the main controller board of a Roboni-I with a (heavily loaded) Propeller Proto Board. The orignial board had five bi-colored LEDs which I replaced with tri-colored LEDs. I've been trying (with some success) to come up with fun light displays for the five LEDs. I'm hoping to add additional patterns it can display.

    I like your method of of having a code for the patterns. I've been using different algorithms for each display.

    Helping to make gagets for Buzz Lightyear. Do you have one the best jobs ever?

    In the end is a standard address-type stamper, though it has a cool Buzz Lightyear message.

    The LEDs are standard, mono color. The code actually controls eight but the mold shop changed the design a bit and just put 7 on the device.

    Initially I was expecting it to have an inkjet head controlled by the propeller (not that that would be a stamp) but it's still cool to see the propeller making the world a happier place for non-programmers too!

    Jon,

    Another great job well done and the Mouse and Buzz Lightyear is glad to someone like you helping them out
