The increasing popularity of unmanned aerial vehicles (drones) has created a lot of security issues and possible privacy threats. Drone manufacturers have made them easy to fly so that any person without any experience can buy one and fly it without reading the instruction manual first. This has made them attractive for consumers, but also […]

Ultrasound, also known as sonography, is a medical procedure which uses sound waves to get images from inside the body. It is used to help guide biopsies, diagnose causes of pain, examine a baby in pregnant women, diagnose heart conditions etc. High- frequency sound waves are transmitted to the body using a small transducer (probe),

A crystal oscillator is an electronic circuit that generates an electrical signal with a very precise frequency. To achieve this, it uses the mechanical resonance of a vibrating crystal made of piezoelectric material. The first crystal oscillator was invented in the late 1920s by Walter Guyton Cady who was interested in submarine detection with ultrasonic waves.

The MAX11311 is industry’s first configurable high-voltage mixed-signal I/O that allows user-defined ADC, DAC, or GPIO functionality. Programming MAX11311 is very easy. A nice GUI tool helps to generate the right register values. If you want to make a universal signal processing board with a good number of I/O, it often gets very difficult to

This tutorial will show you how to build a jacket with turn signals that will let people know where you’re headed when you’re on your bike. We’ll use conductive thread and sewable electronics so your jacket will be soft and wearable and washable when you’re done. Enjoy! A version of this tutorial is also on my

Inspiration What if I told you that 2+2=Red!?!? What!?! I know this sounds crazy but for people with synesthesia this might be their reality. Synesthesia is defined as “the production of a sense impression relating to one sense or part of the body by stimulation of another sense or part of the body.” This is

The A1230 is a dual-channel, bipolar switch with two Hall-effect sensing elements, each providing a separate digital output for speed and direction signal processing capability. Additionally, it features a Magnetic Encoder for enhanced functionality. The Hall elements are photo lithographically aligned to better than 1 µm. maintaining accurate mechanical location between the two active Hall
Dual-Channel Quadrature Hall-Effect Bipolar Switch Module for Magnetic Encoder Continue Reading
We start this week with very sad news indeed. You may have heard about the horrific fire on the dive boat Conception off Santa Cruz Island last week, which claimed 33 lives. Sadly, we lost one of our own in the tragedy: Dan Garcia, author of the wildly popular FastLED library. Dan, 46, was an Apple engineer who lived in

I made a xylophone that uses an Arduino Mega to detect when a note is struck, and generate MIDI output. This project is wondeful because I essentially made a xylophone, a drumkit, and any other MIDI controlled sound instrument, with one tool. The following steps will outline what I used to make this xylophone.
