From the project
A portable bluetooth music player based on ULTRAKILL
ULTRATERM is a miniature replica of an ULTRAKILL settings terminal ( like the one used in cybergrind ), that acts as a bluetooth audio player.
The terminal sits at around 125mm tall, with a 57x104mm footprint. It was designed to look cool, be fairly accurate, and act as a (mostly) stand alone device. It features a: - 2.8" TFT display - Touchscreen + 3 physical buttons - A 2000mAh battery - Bluetooth headphone support - USB-C storage interface - Removable SD card storage ( and a custom microSD card adapter ) The case is designed to be entirely 3D printable, and assembled without adhesive or…
