Audio Keyword Recognition
In addition to our standard form-factor boards, Teensy is available as a member of SparkFun’s MicroMod range of M.2 mix-and-match processors. Maker Evan Rust selected this board to pair with SparkFun’s MicroMod Machine Learning Carrier for a simple yet powerful keyword recognition project.
Using publicly available datasets, Evan uploaded […]
Quad Channel Audio Adapter for Teensy 4.x
Members of the Teensy community will be familiar with our Audio Adaptor Board, which adds CD-quality sound to your Teensy 4.x projects.
It uses the low-power SGTL5000 stereo codec from NXP, but forum user Bob Larkin performed a detailed exploration of this chip’s performance vs. TI’s PCM1808, resulting […]
Transforming Power Wheels
Various makers have created “working” Transformers over the years, but most of them can’t be ridden in since they’re full of … robot.
YouTuber James Bruton, who we’ve featured on the blog before, solved this problem by creating a Transformer that you can ride on, like a Power Wheels […]
FastLED Music Visualizer
Haybur has shared a template to help developers get started with Teensy-based music visualization projects.
While it is designed for use with a custom PCB, it can be adapted to any Teensy/Audio Adaptor Board project. The project assumes a 16×16 LED matrix, and takes care of all the FFT […]
Budget Mechanical Keyboard
Brad shares a project from the depths of COVID lockdown: a budget DIY mechanical keyboard. As a student, Brad yearned for a fancy mech, but a lack of funds resulted in a far more impressive route: soldering a Teensy directly to the switches of a completely DIY typing tool.
The […]
minichord Electronic Harp
The bizarre Suzuki Omnichord looks a bit like a prop from a weird 80s sci-fi show, but is in fact a real instrument, developed to create harp-like arpeggios, and first introduced in 1981, then re-introduced as the OM-108 in 2024.
Those familiar with its odd shape and interface will […]
dRehmFlight VTOL
We’ve all dreamed of flight, but Nick Rehm’s dRehmFlight VTOL brings that dream closer for hobbyists and hackers looking to get their weird contraptions airborne.
Based on a Teensy 4.0 plus TDK MPU-6050 six-axis IMU, the project is intended to teach flight control and stabilization concepts, rather than competing with […]
ActiTouch – VR Touch Detection
Yang Zhang, Wolf Kienzle, Yanjun Ma, Shiu S. Ng, Hrvoje Benko, and Chris Harrison have created ActiTouch: robust touch detection for on-skin AR/VR interfaces. Instead of traditional handheld controllers, the system uses the body as an input device.
A smartwatch-style wristband contains a Kinetis K20 microcontroller running firmware prototyped […]
Two-Key Keyboard
Adrian wanted to create a silly surprise for their friend and avid player of the rhythm game OSU!, with the bonus goal of getting a chance to learn about electronics. The result of this was an adorable two-key keyboard based around a Teensy.
Combining some spare keyboard switches and a […]
One Hacker Band
Aaron Todd is the eponymous hacker behind the One Hacker Band — a social media sensation that uses electronics to make musical instruments play themselves via MIDI. Guitars, percussion, a Novation keyboard, vocals — OHB’s got it all, and it’s all powered by Teensy!
Aaron takes us behind the scenes […]
Machine Learning Prosthetic Arm
YouTuber James Bruton wanted to create a prosthetic arm with natural control. At first, the idea was to use a brain-computer interface, but obtaining reliable data this way proved more difficult than expected.
So James pivoted to using machine learning to train the arm to mimic his real arm […]
MIDIHEX – Harmonic Table MIDI Device
The C-Thru Music AXiS-49 plug n play music interface was a velocity sensitive MIDI input device designed for composing and arranging music. Ben Glover’s Midihex is a new MIDI controller inspired by the AXiS-49, with 98 playing keys and an additional five function keys.
What the original […]
Electromagnetic Appliance Identification
Robert Xiao, Gierad Laput, Yang Zhang and Chris Harrison have used a Teensy to prototype Deus EM Machina: on-touch contextual functionality for smart IoT appliances.
In a world of increasingly app-controlled devices (I need three different apps just to turn my lights off at night, for example!), what […]
Teensy-Based 4.1 Computer
Dylan Brophy aka Nuclaer Tech has created a Teensy 4.1 carrier board called the Teensy 4.1 Computer, which equips the microcontroller with SBC-like ports and form factor.
Four USB ports, an Ethernet jack, and high-quality audio output make it ideal for synths, game consoles, computer emulation, and other […]
