Over the years, I've designed everything from silicon chips to circuit boards and from brainwave amplifiers to steampunk Prognostication Engines (don't ask). I've has also been at the forefront of Electronic Design Automation (EDA) for more than 35 years.
Adding interesting sound effects can dramatically enhance the impact of hobby projects and even commercial systems. One way to do this is by means of the WAV Trigger audio processor.
Turn a discarded valise and some audio tubes into a mesmerizing light show using Neopixel LEDs, a MEMS microphone, and a SparkFun audio tone processor.
Turn a discarded valise and some on-sale audio tubes into a mesmerizing light show using Neopixel LEDs, a MEMS microphone, and a SparkFun audio tone processor.
Make a novel clock and have fun tracking time using an Arduino Uno, some NeoPixel rings from Adafruit and a 3D printer to make a stylishly cunning chronograph.
