Technical issues prevented a full 5-mile pass, but a shorter 3-mile run resulted in the fastest 1st, 2nd and 3rd mile speeds in the history of Bonneville Land Speed Racing, with peak GPS speeds of 447.9mph and a 3-mile average of 420mph. Watch the world’s fastest* Teensy, complete with data overlay, in the video below!
The Teensy 3.6 has a USB host port (requires soldering of pins and USB Host Cable), and the ability to read and write voltages, as required to interface with a Eurorack system. This makes it the perfect intermediary between the two, and completely obviates the need for a computer.
With the addition of some 1k resistors and standard 3.5mm Eurorack sockets, plus code to read and store button presses in an array, a simple yet effective pattern sequencer can be realized. Additional detail can be found on Sebastian’s blog, while the example code resides on GitHub, and a sequencing demo can be found in the video below.
NOTE: PJRC recommends caution when interfacing Eurorack signals with Teensy. The Teensy 3.6 pins can be damaged by voltage higher than 3.3 volts, or below ground. Many Eurorack modules use -5V to +5V or -10V to +10V signals. Opamps, buffers, or other circuitry are typically needed to safely connect these higher voltage signals to Teensy’s pins.
For his latest project, he ditched the retrocomputing angle and went full futurism, using a Teensy 3.1 as the basis of his Dystopian Drone.
The Teensy outputs a continuously-evolving synthesized saw wave sound, which is then broadcast worldwide at http://echo.lurk.org:999/ef1j.mp3 as well as locally on 89.3 FM via a simple external transmitter. The result is deliciously chilling, and provided the perfect sinister soundbath for the authoring of this blog post.
