Here’s a simple audio clip player by Paul of Dorkbotpdx: The hardware is pretty simple. It’s just a Teensy 3.0 that “plays” the audio using a PWM pin. The PWM is amplified to a 9V signal using a NPN transistor, then a pair of transistors buffer the signal to the current required to drive an 8 ohm […]

24×30 RGB LED matrix
Madox is designing a RGB LED matrix consisting of 30 addressable RGB LED strips with 24 LEDs each. The LEDs are controlled through the Teensy 3.0 Arduino board over an I2C interface. The project is a LED lamp that will be mounted on the wall. It comprises of 24 LED Strips of 30 LEDs each […]
A look at the Teensy 3.0 testbed of nails
SJaak refers us to this article by Paul Stoffregen about how they test new Teensy 3.0 boards using a “testbed of nails.” Essentially the Teensy 3.0 crew has developed this testing interface which gives them a way to test every new board by bringing it into contact with the test jig’s pins. The result is […]
