-# xcb-2024
-Cross Communication Badge to gamify conference encounters
+# xcb-2024
+The cross communication badge (xcb) was created for a two day internal company conference. Its main purpose was to gamify communication and networking across the 150 participants.
+
+<img src="img/xcb-2024-top-bottom-revb-photo-front-assembled-off.jpg" width="800"/>
+
+<sup>Additional images can be found in the [img](img/) directory</sup>
+
+# Features
+The badge features three modes: Conference, Play and Sensor.
+
+In <ins>conference mode</ins> each badge transmits its unique ID every 30 seconds. Any badge receiving two transmissions from the same badge within 100 seconds will count this as a unique contact. Due to limited infrared power, close proximity between sender and receiver is assumed. The amount of unique contacts is displayed on the LCD screen to gamify in-person encounters.
+
+In addition secret badges are hidden at the event location, offering a treasure hunt for those who want to explore beyond the main conference tracks. The needed hints are printed on [flyers](xcb-2024-flyer.pdf) handed out with the badge. The discovery of these secret badges is encoded in the display as single segments to easily compare progress between participants.
+
+It was important to me that the badge could be re-used after the conference so I added two additional modes.
+
+In <ins>play mode</ins> the badge features a version of the popular game Simon https://en.wikipedia.org/wiki/Simon_(game) (in Germany known as Senso https://de.wikipedia.org/wiki/Senso_(Spiel)). People can chase a high score, which can also be displayed when in conference mode.
+
+In <ins>sensor mode</ins> the badge transforms into a temperature and humidity display with min/max functionality. Powered by USB the badge can continue to operate in the home or office.
+
+On the back of this stacked PCB assembly (preventing any electrical shorts while wearing) the participants can find a [silk screened word puzzle](img/xcb-2024-bottom-revb-render-back.png) containing the names of the employees of the company.
+
+## Video
+There is a short video highlighting all badge features on youtube: https://youtu.be/XA52-lHTVL4

+
+# Hardware
+The hardware is [straight forward](kicad/xcb-2024-top-revb-schematic.png). Powered by two CR2032 coin cells or USB, a STM32, a three digit LCD display, an infrared receiver/transmitter, a buzzer, four capacitive touch buttons and a temperature and humidity sensor. All neatly packed into a wearable badge.
