For 2016 Maker’s Faire at New York, Will Ware made Megachordotron, a Teensy powered MIDI controller with a touch sensitive keysboard. In his own words: “It’s intended for people (like myself) who are too clumsy to play a guitar“. This design is open-source and he has posted all the files on Github. In the following Youtube video, he shows the demo of his instrument.

Alex Whiteway, Sungjoon Park, and Rameez Qurashi (students at Cornell) designed FPGA-driven mechanical arms to solve Rubik’s cube. They used three mechanical arms to hold and rotate the cube. Each arm consists of two servo motors: one for rotating the arm and another for controlling the grip of a mechanical claw attached to the arm. With the help of the arms, a camera scans all six faces of the cube. The faces information is passed into Rubik’s cube solving algorithm, which then determines the moves needed to solve the cube. The move instructions are fed to the FPGA, which then generates PWM signals for the

Nevyn’s entry to the 2016 Hackaday Prize contest is a modular weather station built using a number of sensors mounted on a general purpose circuit board. The sensor readings are captured by ESP8266 and sent out to the internet. The initial project supports the following measurements: – Air temperature – Air pressure – Humidity – Ground temperature – Light intensity (luminosity) – Ultraviolet light intensity – Wind speed – Wind direction – Rain fall The weather station will be designed to work off-grid with limited capacity to store data for upload at a later date should an Internet connection fail temporarily.

Chronio is an Arduino-based 3D-printed wrist watch designed by Max.K. The watch fits in a 22mm watch strap and runs on a 160mAh button cell for several months. A 96×96 pixel Sharp Memory LCD is used for display. Besides telling time, you can play a simplified version of Flappy Bird on it. Features The ATmega is in Sleep mode for most of the time and only runs once a minute to update the time or if a button is pressed. This reduces the current consumption to 2uA. Sady the display needs a certain pulse every second, which requires a complicated

A nebulizer is a medical device that is used to transform a liquid medicine into aerosol droplets so that patients with pulmonary diseases can easily inhale the medication into lungs. Medical nebulizers are commonly used for the treatment of COPD, asthma, cystic fibrosis and other respiratory diseases. This application note from Microchip demonstrates an implementation of driving a piezo mesh disk in a vibrating mesh nebulizer demo. The demo system features a Microchip 8-bitPIC16F1713 microcontroller-based piezo mesh disk driver board and a nebulizer plastic housing. A significant innovation made in the nebulizer market is vibrating mesh technology. Basically, a vibrating mesh nebulizer is composed of a liquid reservoir with a
