Venti-POV – LED Poi

Po Ting made some awesome LED-POV poi that has some really impressive image rendering.

This design includes 80 pixels and a touch-sense pad to act a control button.  It takes advantage of the high performance features of the Teensy 3.6 to achieve high frame rate that allows for really detailed images as the LEDs move.

A couple of years before this project, Po Ting didn’t have any experience with Arduino or using micro controllers.  Through trial and error as well as a lot of community support, he was able to create this incredible LED project.  Some of the projects and libraries that really helped on the journey were Mortonkopf’s POV Project, the FastLED library,  KurtE’s DMA-SPI library, and Duff’s Snooze Library.

Stormtrooper Voice Changer

Shawn Hymel over at SparkFun put together a compact Stormtrooper Voice Changer.

While there are some pre-built voice changers out there for defenders of the Empire, this solution is both compact and low cost.  With only a handful of parts – a Teensy 3.2, Prop Shield Board, small speakers, a microphone, and a battery – this solution can fit entirely in a helmet.

This project makes use of the Audio Design Tool as well as TeensyTransfer by FrankB.

Detailed instructions (and code) on how to up your cosplay game by sounding like a Storm (or Clone) trooper can be found on this SparkFun blog page.

May the Force be with you.


Mega/Due Shield Breakout Board

Daniel Gilbert (Tall Dog on Tindie) has developed a breakout board that let’s you easily use Arduino shields  with the Teensy 3.5 or Teensy 3.6

This convenient board includes all parts needed to assemble a breakout board that allows you to connect a Teensy 3.5 or Teensy 3.6 to shields designed for the Arduino Due and Mega.  It features switches to select between USB or external power as one to set the US host port’s power mode (used for the Teensy 3.6).


Soft Power Button

Christoph put together a soft power button with sense output to power up a Teensy and allow the application to turn itself off the power when necessary.

The project started with list of desired features including: one button to enable power to a circuit, keep the power on as needed, sense the output so that the microcontroller can sense the power button’s state and turn itself off when told to do so, use a single LiFePO4 battery, and use no specialized parts.  Christoph was able to make this happen using a Teensy 3.6, a 5V step up/down regulator, a PCB he designed for the pushbutton, and a few passive parts.

Code for the project can be found on this project page.


Arduino Music Player

Jarkko Lempiainen has improved his Arduino Music Player to play MOD, S3M, XM, and IT music files

Originally built on a Teensy 3.1, the player has been upgraded to a Teensy 3.6 to take advantage of improved performance and increased memory.  It features 8 channels that can be individually controllers and supports various effects such as vibrato and arpeggio.

Code for the project is available on GitHub.

IR PC Remote & YouTube Controller

Shawn McCombs added IR remote capabilities to his laptop so that he could control his YouTube playlist from the comfort of his bed.

Some older laptops don’t have IR sensors or remote control capability, but Shawn worked around that by using a Teensy, and IR sensor, and the IRremote library.  This project allows you to take a remote and reprogram the buttons to control your laptop.

Code for the project is posted on GitHub.

Portable 2 Player Arcade Console

Lili Bykerk made a pretty cool portable 2 player arcade console.

This controller uses a Raspberry Pi running RetroPi to run the game ROMs and a Teensy 3.2 to act as a game controller using a modified version of the USB Joystick code. The controller also features an HMDI port to plug into your TV as well as 2 USB ports in case you want to plug in your own arcade controller rather than use the 2 that are built-in.

Lili put together a great Instructable on the project that details how to build your own and also provide the code for the project.


Counter Strike Global Offensive with Wii Nunchucks

Dave retrofitted a couple of Wii Nunchuks into custom controllers for Counter-Strike: Global Offensive (CS:GO).

Dave was already working on a project using two Wii Nunchuks for a custom controller when he came across a Reddit post about using a Wii Nunchuck to aim when playing CS:GO.  He had a breadboard on his desk with a Teensy-LC, some Nintendo Extension CTRL (NXC) breakout boards he developed, and some Wii Nunchuks wired up.  After a bit of programming he was up and running playing CS:GO with his new controllers.

Additional details and code for the project can be found Dave’s Parts Not Included site.
