Original Engelbart Keyset
Ken Shirriff retrofitted Douglas Engelbar’s 1960s era keyset from his famous “Mother of All Demos” to connect to USB so that it can be used with today’s computers.
We love Ken Shirriff projects, and Ken Shirriff seems to love Teensy too, if the number of our boards we’ve seen […]
Guitar Amp Modeler/Multi-FX
HexeFX, whose Jaws-themed guitar effects pedal we’ve featured in the past, is back with the fully open-source TGX4 amp modeler and multi-FX pedal.
The project consists of both software and hardware. The software is designed to be compatible with a range of Teensy-based platforms beyond the dedicated TGX4 […]
Spooktacular Halloween Show
Christopher Rees loves LEDs. So when he got the request to put together a display for the Tremonton City Lions Club Pumpkin Walk, he of course went all-in.
His Teensy 3.2-powered display features 184 RGB 5050 LEDs, three 10-watt RGB floods, three 20-watt RGB floods, and a whole bunch of […]
PDP-11/70 Emulator
Folkert van Heusden has added Teensy 4.1 support to a microcontroller-focused PDP11/70 emulator.
The system is capable of running UNIX 5 with disk, tape, and serial support, plus 4MB of RAM, an MMU (memory management unit) and high-performance 16-bit 11/70 CPU. It takes around a minute to boot, though […]
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 […]
Rubik’s Cube Solving Robot
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.
Virtual reality can be incredibly immersive, […]
