Despite the name, not every project we see using Teensy is necessarily that diminutive.

This adorable pre-amp from Marcell Marosvolgyi shows what’s possible with the small form factor, however, using a Teensy 3.2 plus Audio Shield to provide bass and treble tone control, surround sound processing, and compression, in a gorgeous little enclosure.

Adding a stackable 20-watt amplifier using Adafruit’s MAX9744 breakout board results in world’s cutest hi-fi stack. Project details can be found on Hackaday, with firmware and a Python script that provides a PC interface on GitHub.
