Robot instrument builds are always fun, but the wiring can be cumbersome. However, this robot friend, built around a toy piano xylophone, requires zero soldering.

This project displays high resolution video generated by an Adafruit Metro RP2350. The HSTX bus outputs DVI video which can be shown on an HDMI monitor. The Adafruit-DVI-HSTX library makes the project easy to write programs like this in Arduino, while displayio makes it easy in CircuitPython.

The Metro RP2350 makes a perfect little game console. The on-board HSTX combined with a DVI breakout can output to a standard television or computer monitor for the display. The USB host connection makes it easy to take input from a keyboard to control the game.
