Rob Reynolds over at SparkFun whipped up some singing skulls just in time for Halloween.
Inspired by a recent trip to Disney World and seeing animatronic magic, Rob grabbed a Teensy 3.6, an audio shield, and some plastic skulls and got to making. He created 4 solenoid circuits using mosfets to trigger the singing skulls. To top it all off, googly eyes were added to the skulls, because googly eyes make everything better.
Pete Prodoehl built a custom QWERTY keyboard in homage to the typewriters of old.
The inspiration for the project came from Pete’s interest in keyboards and typewriters as well as as a fascination with machines, and how people interact with technology . He grew up in Milwakee, the birthplace of the first successful typewriter. Coincidentally, he also lives near a street named fro Christopher Latham Scholes, the primary inventor of the QWERTY keyboard.
His QWERTY keyboard is made of wood, just like the early prototype of the Sholes, Glidden, & Soule typewriter. While Pete feels that he doesn’t quite have the woodworking skills of his father, he is good at creating thing digitally. He asks a compelling questions – are we losing the ability to craft real-world objects in exchange for creating digital objects? He suggests that maybe digital fabrication is the answer and perhaps it can bridge the gab between the two.

Liam Lacey created an incredible custom MIDI controller for Turnado, a powerful audio effects software program.
This custom controller provides a sleek interface to the Turnado audio FX software giving a performer easy access to the software during live performances. Not only are all the controls optimally mapped to the software, but a TFT display provides the real time value of the knobs as well as displays a menu for configuring the controller’s MIDI settings.
Tom Boyd made the ArduServer, a web server built in a Teensy that allows for remote control and the reading of sensors over the web.
The ArduServer uses a Teensy and a WIZ820 ethernet module. The Teensy connects to an LED and light sensor. Users can turn the LED on or off by using a web page. The web page also displays reading from the light sensor and the state of the LED. The LED and light sensor can be interchanged to other input/output devises such as temperature, photo sensor, etc.
The source code for the project can be found here.
This mesmerizing coat is made with 1,000 individual addressable LEDs (picture Edna Mode using her “No Capes” voice to say “No Strips!”) and whit shaggy fur that is not only fashionable, but acts as a diffuser. The individual LED pixels are joined together by flexible wires with spacing of about 2″. Janet doesn’t like to use strips on flexible surfaces because as she puts it, she prefer to never do repairs
The LEDs are controlled by a Teensy using custom hardware and software. The control switches are mounted behind the collar, and multiple battery packs are stored in pockets in the lining, in the back of the coat.
Brown Dog Gadgets has developed Crazy Circuits, an awesome circuit building system that work with Legos.
They feature several different projects including Lego based, interactive wearables, and conductive materials such as paint, thread, and clay. Several different components are available with many of them ready to fit onto a Lego board. They have many project tutorials published to get you going and code for the projects is published on GitHub.
This portable, compact, synth includes a portable speaker and can run off 2 AA batteries or use USB for power. It features 8 note polyphony with each note having 2 voices. This little synth is packed with features. Oh, and the LEDs on the buttons respond to the speed and shape of the low frequency oscillator (LFO)
