Wooblizer – Acoustic Note to Wave Synthesizer
French digital-analog musician Emmanuel Presselin has created a synthesizer capable of taking in acoustic notes from instruments, keys, or vocals using an attached microphone and translating them into waves.
The synthesizer–which he calls the Wooblizer–uses a Teensy 3.6 […]
Foone Turing’s Single-Knob Keyboard
Foone Turing is a Python programmer from California who likes to make strange and wonderful USB keyboards in his spare time.
In a recent project posted to Twitter, Foone used one button, one knob, an 8-segment display and a Teensy to make an extremely minimal and inefficient approach to keyboard user interface design.
Foone’s single-knob keyboard uses a potentiometer to select ASCII characters based on degrees and […]
Model Rocket Flight Computer for 74mm Airframes
Sacramento-based Peregrine Developments has engineered a flight computer called the Randall FC using the Teensy 4.1.
Although rocket design has roots going back to thirteenth century China, modern model rockets have been a source of fascination for hobbyists and professionals alike since the 1950s. Early model rockets consisted of a simple 3″ motor built from a nozzle, […]
Obstacle Avoidance Using An iPad and LIDAR
Shane Wighton, the designer behind the well-known basketball hoop that won’t let you miss, has created a system for obstacle detection that uses the new iPad’s built-in LIDAR scanner.
The LIDAR system works by taking regular readings of a room by sending out tiny pulses of light at targets and measuring the time it takes to return a reflection. In this way, a scan can be taken of […]
Binaural Beat Synthesizer
Instrument maker and artist Greg Francke recently shared a project on Hackaday that uses binaural recording in combination with the Teensy audio library to produce a six channel wave synthesizer capable of generating “complex aural soundscapes.”
Binaural recording is a process that makes use of two microphones strategically located to create a 3-D stereo […]
