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 […]
SparkFun To Manufacture Teensy
We are excited to announce the expansion of our partnership with SparkFun Electronics to include the manufacturing of all Teensy products. Teensy 4.0, Teensy 4.1 and related accessories will now be manufactured by SparkFun in Colorado, USA.
SparkFun will also fulfill direct sales and also sell to other distributors, so you can continue to buy from stores which currently carry Teensy.
We’re taking this bold step with 2 main goals.
1: Reliable long-term supply of Teensy. SparkFun is among the largest and […]
FastLED adds Massive Parallel LED Output
FastLED adds Massive Parallel LED Output on Teensy 4.0 & 4.1 thanks to Kurt Funderburg’s ObjectFLED driver.
The driver uses non-blocking DMA, so you can can prepare the next frame while the current frame draws.

Refractions – LED Art Installation
Michael Horn has designed and programmed a beguiling LED art installation in coordination, Refractions, with fabricators MGA Sculpture Studios. Five 7×5′ panels with embedded lighting create the illusion of waves along the static metal sculpture.
Five Teensy 4.0 boards coordinate the animation of 35′ long WS2815 strips, which […]
Game Boy (SameBoy) Emulator
The Game Boy and Game Boy Color sold over 118,000,000 units during their decade-and-a-half reign, but in case that weren’t enough, emulators like SameBoy allow you to play games like Tetris and Pokémon Gold and Silver on your Linux, Windows, or macOS device too.
Emulating a several-MHz 8088/Z80 hybrid on several-GHz computer […]
MCL65-Fast Apple II Accelerator
We love Ted Fried drop-in CPU replacements for retro systems. MCL65-Fast is a little different, however, in that rather than simply emulating the Apple II’s 6502 CPU. Arduino code runs directly on Teensy 4.1 at 800MHz+, with access to all of the device’s peripherals and slots.
In order to […]
Linear CCD Suite
DrM is a prolific creator of charge-coupled device (CCD) digital imaging projects, and the latest is a full-featured linear CCD suite with an $80 BOM cost that provides capabilities comparable to commercial instruments that might cost thousands of dollars.
On the hardware side, the Teensy 4.0’s 12-bit ADC is paired […]
