DIY Minimoog Synth

Nick Culbertson is back, with an attempt at recreating the “world’s most iconic” analogue synth using a Teensy 4.1.

If you haven’t guessed yet, we’re talking about the Bob Moog’s 1970 Minimoog Model D — the “world’s first” portable synthesizer, which could be played easily and instantly […]

Unconventional 3D-Printed Keyboard

Ben Gruver’s lalboard is inspired by one of the most unconventional commercial keyboards of all time: the magnetic/optical two-piece DataHand.

We’ve seen a number of interesting and unique Teensy-based keyboards over the years, such as one that only has two keys, or one that uses individual […]

Directional Gyro

ElectronDon66 has created a Teensy 4.0-based Directional Gyro heading display using a Ceva BNO085 9-DOF Orientation IMU Fusion System-in-Package (SiP) rather than a magnetometer.

The BNO085 is an interesting package, which combines a triaxial accelerometer, a triaxial gyroscope, a magnetometer and an Arm M0 running Ceva’s advanced MotionEngine sensor […]

vindar has created S.A.R.C.A.S.M: a Slightly Annoying Rubik’s Cube Automatic Solving Robot! This self-contained Teensy 4.1-powered machine is compatible with any standard Rubik’s Cube and requires no external computation to solve cubes.

Designed as an over-the-top desk toy, S.A.R.C.A.S.M. is charged and programmed via USB-C. vindar’s Teensy port […]

MicroDexed-touch DIY Synth/Groovebox

positionhigh has evolved the original MicroDexed port of the popular Yamaha DX7 plugin synth into a fully-blown, self-contained sample synth/sequencer/groovebox!

The project combines a Teensy 4.1 with a TI PCM5102A stereo DAC, and a capacitive touch ILI9341 SPI display. This upgraded design takes advantage of the PSRAM and […]

DIY Motion Simulator

Michael Rechtin is building a DIY Motion Simulator that he hopes will transform computer simulation into a theme-park-like thrill ride with the addition of realistic motion.

Flight simulator enthusiasts will go to great lengths to create the most authentic flying experience, with multiple large monitors surrounding cockpit-like rigs, attached […]

TeensyMix Open-Source Polyphonic Synthesizer

We’ve seen all manner of complicated synth and audio project based around the Teensy 4.1, and which makes GitHub user phjanderson’s TeensyMix synth somewhat unique. Recreating the 8-voice polyphonic synthesizer requires just an LCD display and digital-to-analog converter, with an optional 5-pin DIN for serial MIDI.

In addition to […]

80s Megapixel Camera

Frost Sheridan endeavored to see what could be done to make a vintage Kodak MegaPlus 4.2i usable by implementing the communication interface and building his own frame grabber gadget.

The first digital camera that I can recall seeing was 0.4MP Kodak that stored 24 images on its built-in […]

Dragon Halloween Costume

Industry veteran Nathan “Acorn” Pooley likes making costumes for Halloween. And often, this includes an interactive component such as glowing eyes. For the ambitious “Orange Dragon”, a microcontroller was required in order to achieve the desired mechatronic aspects.

For this, Acorn chose a Teensy 3.1 due to its ease […]

Reel Feel – Haptic Feedback for Virtual Reality

Nathan DeVrio and Chris Harrison from the Future Interfaces Group at Carnegie Mellon University have created one of the most elegant and cost-effective solutions to one of the common complaints with VR in the form of their Reel Feel haptic feedback device.
