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 […]

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.
