Cloud connected Development Board obniz is development board which has 12 IO and WiFi-BLE module. It can be controlled through the APIs on obniz cloud, either through the REST or WebSocket API. obniz API can be used in javascript. So, obniz programs written in JavaScript can run on a webpage, so “Turning on a motor […]

Engineers at Cornell university have created a new system for measuring vitals, which could revolutionize hospital experience for everybody. Usually, getting sick means having to go to the hospital which because of today´s procedures takes almost all your day (if not more), and most of the time is spent in waiting rooms. What if you

Hi guys welcome to this tutorial. Today we will be building a simple temperature monitor using the DS18B20 sensor with a Nokia 5110 LCD Display and an Arduino mega. Introduction The DS18B20 digital temperature sensor gives a 9-bit to 12-bit Celsius temperature readings and also has an alarm function with nonvolatile user-programmable upper and lower

Build a convincing artificial fire effect for the holiday season using NeoPixel LEDs, an Arduino UNO, and a cool mist module. Story This is a project I’ve had on the backburner for almost exactly 1 calendar year. The seed was planted when I toured the Harry Potter Studios last year and saw a fake fireplace

If you have high-powered LEDS, or a power supply, or are trying to control larger motors, you have to get a lot of heat out of your circuit boards. The classic way to dissipate heat is to bolt your power transistor to an aluminum heat sink. That is a slow, messy, and expensive proposition, especially if you need

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),

After $5.5 millions collaboration and a lot of work during the past four years of engineers at Imec, the next-generation electrodes called Neuropixels probe were designed to record hundreds of neurons in the brain. Imec is an international nano electronics research center dedicated to build and test powerful new devices for detecting neural activity within the brain.
The “Neuropixels” probe records brain signals Continue Reading
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 top 10 crystal oscillators from SnapEDA Continue Reading
