Open-Source Electronic Load
Electronic loads are important tools in the EE arsenal, useful for confirming that power supplies, batteries, and other power sources behave as expected. But their expensive prices motivated YouTuber EEforEveryone to create an open-source solution that relies on off-the-shelf PC components for cooling.
A custom Teensy 4.0-powered PCB takes the […]
Digital Analog 2×1 Mixer
PJRC forums member rwalters wanted to build an analog mixer with digital control. The analog signal paths meant less expense, but without sacrificing digital convenience. The result is the PGA2310 2×1 Mixer Project.
Components are mostly socketed, so despite the name, a PGA2311 volume control could be auditioned instead, […]
SATLLA-2B Nano-Satellite
We love seeing Teensy boards in use all over the place, from model rockets to jet-engine powered cars, but there’s something extra special about seeing them in space!
Imagine our joy when Ariel University’s Rony Ronen reached out to let us know that the Teensy 3.6 was being used as the main […]
Luma-1: An Enhanced LM-1 Drum Machine
The Human League, Yazoo, Gary Numan, Giorgio Moroder, Devo, Prince…Roger Linn’s LM-1 drum machine helped create the signature sound of a huge number of artists in the 80s.
After receiving an original LM-1 as a gift, Joe Britt (of Danger Research/T-Mobile Sidekick fame) decided to create his own enhanced version, […]
Kenwood VS-2 Voice Synthesizer Emulator
Kosmo turned to the trusty Teensy 3.2 and Audio Adaptor to craft a replacement for the out-of-production Kenwood VS-2 Voice Synthesizer, commonly used in HAM radio.
The VS-2 is a voice module for the Kenwood TS-850, TS-690, TS-450 and other transceivers, which announces frequency and other settings upon request, […]
Guild of Thieves Game Emulator
Thomas Dettbarn, also know and dettus on the PJRC forums, created a highly portable interpreter for the series of text adventures published by UK video game developer Magnetic Scrolls.
With versions running on Ubuntu, Debian, OpenBSD, macOS, Windows, and beyond, Thomas appears to have tested the the claim that it […]
Lathe Digital Readout
John Knoll had added a set of iGaging DROs (Digital Read Outs) to his old manual lathe, but was starting to feel their limitations. They rely on coin cells and are too laggy for precision work.
Inspired by a video of a digital caliper being read by an Arduino, John […]
Infrared Mirror
The human eye is an amazing piece of hardware, and various tricks and exploits are used every day to create such illusions as movies and Persistence-of-Vision (POV) displays.
Unlike vampire bats and mosquitos, however, the human eye lacks the ability to see infrared light — that area of the spectrum […]
Gamepad to Touch Screen Converter
Mobile gaming is quite popular, but touchscreen input is often less intuitive and precise than traditional controllers. Sinsid created their TUBG: Teensy Unknown Battleground project for a controller could be used to emulate those touch events!
Sinsid discovered that both iOS and Android support external touch devices, so rather […]
Teensy, Arduino Due and Sensors Carrier Board
Sometimes you need an Arduino for a project, and sometimes you need a Teensy — but why not both? 1bit created this Teensy/Due-ette Carrier Board to house a Teensy 3.2 and an Arduino Due (or Mega 2560), connected via I2C, plus a whole bunch of other stuff!
In addition […]
MIDI Bass Guitar
We see a lot of Teensy projects that bring the noise, but how many bring the funk? While it’s hard to say for certain without audio proof to back it up, Lokki’s MIDI bass controller certainly looks capable of putting some serious stank on it.
This unique Teensy 3.6-based […]
Parallel Battery Charger
What do you do when you’ve got a pile of quality Panasonic NiMH batteries and power-hungry robots that need high-capacity charged packs?
If you’re the folks over at PDX Hackerspace, a community-focused collective in Portland, Oregon, you assemble them into bot-ready packs and design a Teensy-powered board to charge […]
MDV microSynth
Marco De Vivo demonstrates (video) with his MDV microSynth even a fairly simple Teensy-based synth leveraging the Teensy Audio Library can produce excellent results!
In this project he creates a powerful instrument from a Teensy and Audio Adapter, plus an LCD display, potentiometer, a 5-Pin DIN […]
Horizon OBD2 CAN Programmable Module
Sebastian Yousef of SIGMAGAMMALabs has created an Arduino-compatible OBD-II device in the form of the Teensy-based Horizon OBD-Interface Module.
Hidden under the dash in most modern cars is a secret portal to a wealth of data and diagnostics. Once purely the domain of repair shops, OBD-II dongles are now available inexpensively with […]
