The Pirate Puzzle RGBPP Badge Addon 

An fun but optional part of the Pirate Puzzle at DC31 

Pirates didn't have a suite at DEF CON 31 this year. Instead, they have a puzzle.

To go along with the puzzle is the Pirate Puzzle badge.

Features:

• Is not actually a puzzle itself (...yet), but can be used as part of the Pirate Puzzle
• Gives you a big glowing PP at night, by default a rainbow PP
• People can plug wires into different parts of your PP and it may change colors
• Has a big black 28-pin DIP ... microcontroller
• There are 8 bits of white data that shoot out after someone touches your PP wires
• Really fancy trace work on the top layer (and it's only a 2 layer board)

For more information. see https://dc31.whiskeypirates.com

When firmware updates are available, they will be at the linked website.
Firmware updates require a TTL UART.
If you don't have one, a USB TTL UART adapter is cheap and easy to get.

Here's the schematic.

Additional notes:

• The PP is meant to be an addon, not a badge. Yeah, it has holes for a lanyard, but that's really meant for hanging it on a wall after con.
• RGBLED will only work on very fresh AAA cells. For longer life, use a lithium primary (1.5V or 3V OK) or recharable lithium AAA cell.
• For a brighter PP, solder the addon connector and place your PP as an addon to another badge.
• Note: due to a firmware bug, version 2 and earlier units LEDs may turn off when plugging in your PP to other badges.
• The Whiskey Pirates 2023 badge solder kit is a simplified version of the Pirate Puzzle.

Purchase includes fully assembled Pirate Puzzle (except the addon connector, you can solder that yourself).

Please note: the power switch is a weak point in the design.
If wearing as a badge, be careful as impacts can break the switch.
If hanging on a wall or for casual presentation, the switch should be reliable.
