  1. Thanks for featuring Yoda guys.

    @Ben Technically any pumpkin that has been carved to display an image is a hack because it took something and made it do something completely different than it was designed to do. Not all hacking is about micro controllers, scripts, robots, or nokia lcd screens.

  2. The death star scene is wonderful.

    While I don’t mean to crap on anyone’s project… LED’s in a lab coat? TWO arduinos? Really? There’s a think called multiplexing and a cheaper board called the Maple if you just needed extra GPIO pins.

    If you bothered to read my blog, you would find that the coat and the marquee are two separate systems. The coat is run by one Arduino that runs 8 channels of software PWM that I built a few years ago.

    The whole marquee is run by a second integrated AVR, and is part of a product I am developing recently that differs from other serial matrix drivers that have an AVR chip per 8×8 Matrix. Instead, my design has one AVR that can run 10 8×8 matrices (1280 LEDS) in a row using only 5 IO lines. I do know a thing or two about multiplexing obviously.

    Before you crap on anything, you should probably take the time to look down at what you are crapping on.
