About true's Nametag SC8

This nametag which keeps your name always upright was rapidly designed and presented at Supercon 8.

Features (both planned and implemented)

• Nametag where your name is always upright
  • or, optionally, waving, wiggling, or static
• 12x RGBLED and several RGB programs
• Infrared message communication
• USB support for power and data, including firmware updates

Specs

• Main MCU: CH592 BLE MCU, 448K flash, 26K SRAM
• Sub MCU: CH32V003F4U6 MCU, 16K flash, 2K SRAM
• Zilog IrDA transciever module
• Awinic AW20054 RGBLED controller

Usage

The buttons on the nametag are recessed. The easiest way to access them is to plug in the nametag via USB, then pinch from the back using your index finger and thumb.

All implemented operations can be manipulated via on the on-screen menus.

Things known not yet to work

• IrDA code is implemented but the linking features aren't tested. There are known bugs and these haven't been addressed yet.
• Messaging features are completely unimplemneted.
• I2C slave is unimplemented.
• BLE is untested and unimplemented.
• Someone requested a scrolling nametag mode. I hope to implement this during SC8.
