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 […]
CTR2 – Ham Radio Human-Machine Interface
Lynovation picked the Teensy 4.1 and Audio Adaptor Board as the basis for their CTR2 (“Control The Radio Too”) Human-Machine Interface for controlling up to 16 ham radios and eight antennae.
CTR2 is a standalone remote touchscreen display, with built-in DSP audio processing, FFT display, a rotary encoder for input, as well […]
Conway’s Game of Life Note Generator
Expensive Notes has been using Novation Launchpad USB Ableton controllers in a novel way, connected to a Teensy 4.1 via USB Host rather than using the intended DAW.
The Launchpad becomes a large 8×8 RGB LED “screen” for the Teensy, as well as an input device, while the Teensy can […]
DIY VR Controllers
Shiny Quagsire (Max Thomas) chose an extremely ambitious project for his high school final project: rather than creating something using the many VR hardware solutions out there, he decided to create his own VR controllers from the ground up.
The eventual solution utilized a Teensy 3.2 with TDK MPU-9250 nine-axis […]
Dalek Synth
Expensive Notes was given a broken Dalek (toy, not an actual homicidal mutant!), which, as is their wont, meant turning it into a synth! Based on a Teensy 4.1 and Audio Adaptor Board, the psychopathic cyborg is now polyrhythmic thanks to Expensive Notes’ creative mods.
The mutant’s antennae and arms […]
Doom Game Emulation with VGA Output
“Will it run DOOM!?” And as emulator maker extraordinaire Jean-Marc has now proven (and to be honest you may have already inferred from this post’s title), the answer is a resounding “OH YES”!
So, how did Jean-Marc squeeze all those demons and BFGs onto a Teensy 4.1? An STM32 port […]
TOPS – The Robot Dog
We’ve all seen videos of Boston Dynamics’ robot “dog” Spot dancing, but $75K is a lot to spend. Enter Aaed Musa’s Traverser of Planar Surfaces (or “TOPS” – “SPOT” backwards!) which can get just as funky at less than 1/20th of the cost!
The project, which was inspired by […]
Ultrasonic 3D Scanner
Alex Toussaint created an ultrasonic 3d scanner using off-the-shelf components for under $100!
What was your fantasy when you were 15? For Alex it was an autonomous drone that could deliver cans of Coke, which he reasoned would require a 3D map of its surroundings. Ruling out […]
Digital Instrument Suite
Jay Ackley has created a collection of musical devices called the NoPlay Digital Instrument Suite.
As Jay’s ambitions grew, it became clear that the simple saw wave output of the original microcontroller he was using was not going to work for his more advanced creations, which led him to […]
Engine Monitor for an Experimental Aircraft
Andy Meyer pilots experimental aircraft pilot and was in need of a good engine monitor to show key metrics on a sunlight readable screen.
After struggling for years with an Arduino-based project, Andy discovered Teensy and paired it with a NewHaven 4.3 inch 800×480 serial display…and it was […]
EBTKS Solid State Tape Drive for the HP-85
Adding new features to old computers is one of our favorite project types, as it keeps hardware out of the trash and gives the device a new lease on life.
Philip Freidin’s description of the EBTKS project certainly sounds like it has been an incredible journey, and the functionality […]

We would love to show your Teensy-based project here.
