Giant Darth Vader Minifig
Last time we saw The Sketchy Maker on the PJRC blog, it was in the form of a giant 3d-printed LEGO Luke Skywalker, in celebration of Star Wars day. Now they’re back, but have taken a turn to the dark side, with a giant Darth Vader minifigure.
The more […]
Vimana – Multi-track MIDI Step Sequencer
After four years in development, Guilherme Martins has released Vimana, a multi-track MIDI step sequencer. Vimana is designed to be open and flexible in terms of software and UI.
Vimana features 16 tracks, with a main clock and division/multiplication per track. Step parameters […]
iSCSI Virtual Disk
Flok works with big, expensive IBM iSCSI (Internet Small Computer System Interface) boxes, so the thought occurred: what about the opposite extreme with a microcontroller and SD card? This experiment on Teensy and other boards yielded interesting benchmark results.
Usually benchmarks measure performance of 1 subsysten. But iSCSI […]
Soft Breakout Board and Touch Reactive Fabric Art
Salil Parekh has been using Teensy LC for e-textile projects, but found it difficult to use while testing and debugging due to its small size, which gave birth to the Soft Breakout Board for Teensy LC.
Similar to a regular breakout board, the Soft Breakout Board brings all […]
WS2812B LED Controller
XForce has created a programmable controller for WS2812B LED strips. The system is based around the Teensy 4.1 and a Nextion display and features remote operation over radio.
The home screen has five shortcuts for favorite effects, which can be combined, looped, and stored on mSD. Strips of […]
RV Leveling Helper
Sometimes the simplest solutions are the best. KD5RXT (Mark)’s “fairly simple” Teensy RV Leveling Helper (TRLH) may not be uncomplicated as a spirit level, it’s a clever solution to a common problem for RV owners.
The helper is placed on RV’s counter to measure whether the surface is level enough. Adjustment info is sent […]
Modded MIDI Foot Controller
Behringer’s 2001 FCB1010 “MIDI Foot Controller” is a curious device. Ten assignable control pedals and expression pedals let you do — well, anything that you can do using MIDI, from controlling instruments, to lighting and effects, to automation.
But what if it could do even more? This was the question […]
Node Web GUI
DragonSF has created a Web GUI for Teensy 4.1 with a focus on audio projects. The system consists of a Node server (with some HTML/JS/CSS magic) and a Teensy library, which communicate via Ethernet to allow interactions with the GUI to affect firmware on the Teensy board.
As such, […]
Loop Pedal with Procedurally Generated Beats
Marius4560 created a pretty rad project for their Human-Computer Interaction course assignment: a Teensy 4.0-based looping pedal that even provides its own unique ideas for beats!
The Audio Adaptor Board-based project generates random rhythms and drum sounds, plus lets the user record a chord progression to jam along to. […]
Engelbart Chording Keyset
Douglas Engelbart gave “The Mother of All Demos” in 1968, introducing concepts such as the computer mouse, highlighting text, and hyperlinking documents, which profoundly impacted computing.
Less well-remembered, however, was Engelbart’s chording keyset, a five-button keyboard-like device that allows the input of characters when pressed in specific combinations. Russ Nelson wanted […]
Debugging with Visual Micro
Visual Micro, creators of a Visual Studio extension that enables Arduino development in the powerful Microsoft IDE, have created a serial debugging tool compatible with the Teensyduino platform.
The plug-in allows you to use breakpoints for step-by-step execution, monitor execution time between breakpoints, and set conditional breakpoints based on […]
Mini MIDI Controller
Nick Culbertson, aka Moby Pixel on YouTube, recently acquired a Teensy 4.0 and some tiny breadboards. Nick liked the aesthetics of the Teensy/tiny combo so much that it turned into a “world’s smallest MIDI controller” attempt!
Nick had been eyeing Teenage Engineering’s new EP-133 K.O. II sampler, but […]
Fancy PC Fan Controller
CryHam, creator of the Kacey and KC4 Keyboard Controllers, has created the “Fancy” PC fan controller based on the same code.
The device can regulate seven analog or PWM fans, with RPM detection and display, automated fan power adjustment based on DS18B20 temperature sensors, and an ST7735 […]
LMN-3 Open-Source DAW
What do you get when you cross a Raspberry Pi 4 with a Teensy 4.1 with a Teenage Engineering OP-1? Perhaps something like the LMN3 from Fundamental Frequency!
This self-described “open source DAW-in-a-box” leverages the Pi-based Tracktion Engine DAW tools with a Pimoroni HyperPixel 4.0 display, and a Teensy interfacing […]
