Parts

If you want, you can purchase the components individually and assemble yourself. If there’s enough interest, I will offer a packaged solution.

• 14 key Wireless RF Remote + LED RGB Controller for WS2812B
  • This is the hardware controller for the LED’s which includes the remote.
  • There are other RF remote + controller combos out there, and the “Add DIY” button because it allows you to cycle through specific patterns.
  • Unfortunately, controlling the brightness isn’t intuitive (or documented). To change brightness, uou must select a solid color and then hold down the “Speed -/+” button to change.
• WS2812B RGB LED Strip 144 pixels
  • This is where the magic happens.
  • 1m, 144 pixels provides the best patterns with highest pixel density.
  • There are 3 types of shielding (covering) when ordering:
    • IP30 (no shielding) allows for maximum flexibility; however, is the most likely to break
    • IP65 is nice but is stiffer and the silicone shielding makes it tricky to feed through the webbing.
    • IP67 will not fit throught the nylon webbing, but is waterproof
• Portable battery
  • This one uses Micro USB. If you want to use a different battery, then make sure you find a Barrel Jack adapter which fits.
  • There are batteries which hold more power, and this one works well considering weight, storage, size, and form factor.
• 5.5mm x 2.1mm Barrel Jack to Micro-USB Cable
  • Used to connect the Micro USB Power Bank to the LED Controller.
  • If you want to use a different battery, then make sure you find a Barrel Jack adapter which fits.
• Tubular Polyester Webbing
  • You’ll need at least 4 feet.
  • White diffuses the light better, but black has a better aesthetic, IMO.

Case

For the case, you can use the two following options:

Plastic craft case

• 4”x6” Craft Case
  • This will hold the electronics and battery.
  • A 3D Printable case is currently being worked on
• 4”x6” Vinyl Envelope
  • Since most badges are 4”x6” or less, this should be able to accomodate most badges provided by conferences.
• 4”x6” Index Card
  • Optional. You only need 1. This is to provider a backer for the badge and hide the electronics.
• Hand Riveter Set
  • Somewhat optional; however, this is the best solution I found for affixing the badge sleeve to the craft case. Optionally, you could use Super Glue or E6000; however, it does not adhere well.
• Matches
  • Used to remove frays after cutting the webbing
