Csiko writes: The ingredients in this do-it-yourself christmas project are a gyroscope built of a felt pen, a bunch of old CDs, an embedded microcontroller (MCU), some LEDs and a big portion of nerdism. While the gyroscope spins, the MCU controls the LEDs so that a writing appears in realtime. Nice project, but it definitely needs a nerd girlfried to appreciate that.
