Not only is Adam a bit obsessed with the trackball mouse, but he’s also a billiards fan. So when he saw a character using a 9-Ball mouse in the movie Oceans 8, he knew he had to have one.
He used an arcade trackball as a base and added some LED arcade buttons. A 3-D printing housing was create to custom fit his hand. A custom PCB made it easy to wire the buttons and trackball to the Teensy and also made it easy to mount the electronics.
The USB HID functionality of a Teensy along with the Encoder library made quick work of the code for the project.
Ben McInnes, Adoné Kitching, Jason Sutherland, and Luc Wolthers created an amazing game – Guitar Wizards.
Guitar Wizard is a game based of the classic Guitar Hero game. Rather than play for points, the players battle each other, head on, playing riffs on the modified Guitar Hero controllers, shooting LED notes at each other. The opposing player blocks the notes by playing their own notes and chords.
This amazing, interactive game is powered by a Teensy 3.6, has over 2,000 WS2812B LEDs, and uses the FastLED library.

PWM is commonly used to control servos and electronic speed controllers (ESC) and is useful for many projects. This tutorial explains PWM and introduces how to wire up and command a servo Part 2 of the tutorial go over reading PWM commands.
The tutorial features the PWM Backback by Bolder Flight. This handy backbpack makes it easy to hookup RC Servo Motors to your Teensy. It features 8 channels of 16 bit PWM output; bused ground, power, and standard servo connectors; and option SBUS communication input.
Darryl McGee and Steve Barile of Conductive Labs have developed the NDLR (pronounced Noodler), a 4-part poly sequenced arpeggiator, chord and drone player based on the Teensy 3.2.
The guys at Conductive Labs came with a unique solution to break down music theory into knobs and controls. The NDLR has four parts that can play up to 8 synths. The PAD part is a chord player. Press one of the 7 chord buttons and all the other parts change notes to match. There are also 2 “Motifs” which are sequenced arpeggiators. The Drone part can play a single continuous note like a traditional drone does… or choose from various retrigging options, such as having the note retrigger on a chord change, the down beat, every beat, up beat, etc.
Among the many advanced features packed into the NDLR is a pattern and rhythm editor that lets you create custom arpeggios. You can also save your patches and settings for later recall with the 8 global slave slots, 20 user patter slots, and 20 user rhythm slots.
John Grant built MyComm, a very clever solar global messaging device.
MyComm is a portable messaging device that allows users to send messages from anywhere on Earth. It uses the Iridium satellite system to offer coverage beyond traditional cellular and WiFi networks. Because it’s solar powered you don’t need to worry about battery life.
