Dungeons and Dragons Hit Point Tracker With E-Ink Display
thingiverse
A case for my Hit Point Tracker with e-Ink display. It uses an Arduino Mega 2560 and HC-06 bluetooth module. Instructables project link... https://www.instructables.com/id/Dungeons-and-Dragons-Hit-Point-Tracker-With-E-Ink-/ I wanted to create a hit point tracker that displays all of the players hit points in a normalized scale, so you can see exactly who needs healing the most and how poorly the whole party is doing. It connects via Bluetooth to an Android phone which displays all the buttons you need to control your party's status. It's powered by a replaceable 9V battery. The current state is saved to EEPROM so you can swap out the battery without losing everyone's current hit point values. Components needed -Arduino Mega 2560 -HC-06 Bluetooth module -400x300, 4.2" E-Ink Display Module -RobotUI app from the Google Play Store -3 resistors. Any value, but they all need to be the same value. -9V battery -9V battery connector -Wires and solder -(optional) Some kind of case. -(optional) Power switch. You could just remove the battery, but a switch is more convenient. -(optional) Cylewet 55 breadboard. If you hate soldering as much as me. Tools -Probably a soldering iron -Wire cutter -(optional) 3D printer for case
