In this post, we will learn how to make Universal-Air-Slide-Whistle-1000: The slide whistle is a musical instrument often used for comedic effect due to its silly sound. In this instructable, we teach you how to make an air slide whistle! What is an air slide whistle? It follows the same idea as air guitar where […]

ROHM recently announced the 1608-size high accuracy blue-green chip LEDs, SMLD12E2N1W and SMLD12E3N1W. These products support the adoption of Color Universal Design (CUD) in a variety of applications, such as fire alarm system indicator lights, industrial equipment warning lamps and public transportation information displays. Color is considered to be one of the most important means

TL;DR – I wanted all of my AV components to turn on and change inputs as soon as I started Airplaying music to my Apple TV from my iPhone, so I popped open the Apple TV, wired up a photocell sensor to an Arduino Uno, wired up some Infrared LEDs, wrote some code, and made

Practicing the art of time-lapse photography without an intervalometer is doable, but not particularly efficient. And while any decent photo equipment store will be happy to sell you one, you can go the DIY way and build your own intervalometer based on the excellent Arduino platform. Theoretically, building an Arduino-based intervalometer is as easy as connecting an infrared

The intention was to build the most universal soldering controller I can think of. It can drive any low voltage (upto 24V) iron with thermocouple or resistive sensor, in series with the heater, or separate. Here is a short list of features: – power: 9-28V, AC or DC – 2 separate heater control channels –

Signal relay is almost an „ideal component“ thanks to a practically zero distortion and a total isolation of a switched signal from a control one. That is naturally one of the main features of all electromechanical relays, but at signal relays it´s especially valued, as we usually require switching of relatively small signals. Favorite and
