70 LED matrix in a jack-o-lantern

Posted on Friday, October 29th, 2010 in Holiday by Ian

Hack a Day made a Jack-o-lantern that shows animations on a LED matrix.

Mike shows you how to design and run a multiplexed display with an AVR. Then he guts a pumpkin and installs 70 LEDs with power tools.

Gourds, LEDs, and power tools, what’s not to love? We’re big fans of blinken-pumpkins.

  • KH: Really? They are digital inputs driven by an MCU. The MCU GPIO probably has diode clamps and ESD protection. Have you experienced such failures? Please...
  • KH: Neither. Google "Marco Schweighauser’s 8-bit virtual Javascript CPU" and see the first result. Sounds more like a very limited feature toy CPU.
  • Alan: "8-bit x86 like CPU" - isn't that an 8080, or Z80?
