About the Badge

This years badge is a badge. You can wear it around your neck with a laynard if you prefer. It lights up, and it will scan for and display the number of other BLE enabled Badgelife badges, and other Bluetooth devices.

Instructions for Use

To use the badge, the bottom right key is the Exit / Menu key. Press this to get to the menu. The top two rows of keys are light patterns. Press one of these to change the light mode. Press the lower right exit key to return to the menu. The 3rd row down, left most button will begin scanning for Bluetooth Badges, and display a count.

Build Guide

Your badge will likely come as a kit. Below is a full build guide, but you likely have the leds already pre-installed on your badge.

  1. Install the Key Alignment Diffuser. This laser cut acrylic piece only goes one way, line up the notches on the top of the acrylic with the gold plated holes on the badge. Place the keys into the grid and through the PCB one at a time. Finally put something stiff ontop of the keys, like a book or piece of cardboard, and flip the badge over. Now solder the keys in place.

  1. Solder on battery pack onto the back of the pcb. The red wire goes through the + hole, and the black wire goes through the - hole. Use the double sticky tape to attach the pack to the board.

  2. Add the OLED screen to the front of the pcb. The screen should go off to the right from the pins. J6 is the OLED screen header, its closest to the SD card slot.

  3. Solder on the SAO headers if you wish. There are two on the upper left and right sides of the badge.

  4. Turn on badge, bling out.

Bonus **** Format an SD card to Fat32 and stick it in. Flash the newest firmware and your badge will record in a text file all the BLE devices it sees. Neat!

Troubleshooting

LEDS are flickering. -- Possibly a bad solder joint. Use a soldering iron on low heat (300 deg C or less) to remelt all four pads on the led. The LEDs are heat sensitive, so be careful.

Badge is stuck red and showing "Initializing" -- Batteries may be low. Change your batteries. Sometimes the badge will just take 10-20 seconds to boot due to shitty code. We are still working on that (Sorry our bad...) Also if you leave the OLED off, the badge may not boot due to improper resistance. Put your screen on.

** Important ** The color wave mode has some delays coded in, so mash the exit / menu key to return to the main menu.
