Summary This reference design is an anti-drowsiness alarm, which aims to keep the drivers alert by disrupting one’s drowse. According to the study by U. S. National Highway Traffic Safety Administration (NHTSA), drowsy driving is the primary contributor of at least 100,000 auto crashes a year. Statistics shows that most crashes caused by drowsy driving […]

A few months ago, Andreas presented a nice version of the “throwie” (a LED packed with a small battery that you can throw & see shining for hours) using an ESP8266 instead of a LED : a “wifi throwie”. He could not make it work with button cell batteries (the ESP8266 draws too much current)

Although Intersil’s ISL29501 time-of-flight (ToF) signal processing IC doesn’t have anything to do with the lighting applications I normally cover, I felt compelled to bring it to your attention because it’s one of the most innovative LED applications I’ve seen this year. The device requires little more than an external emitter (LED or laser) and

Operational amplifiers (OPAMPs) are high performance differential amplifiers in integrated form that can be used in many different ways. A typical OPAMP has a non-inverting input, an inverting input, two dc power pins, one output pin and a few other fine-tuning pins. On the following image you can see a typical diagram of an operational

This is a simple tutorial to create an EMF detector. You can use Arduino for this job, but is better use a microcontroller called Attiny85. It is possible program it throe the Arduino interface. What is a Magnetic Field [from Wikipedia] An electromagnetic field (also EMF or EM field) is a physical field produced by

AtmegaS128 – the first µC Rad Tolerant device for Atmel – delivers full wafer lot traceability, 64-lead ceramic package (CQFP), space screening, space qualification according to QML and ESCC flow and total ionising dose up to 30 krad (300 Gy Si) for space applications. The ATMegaS128 is “latch up” immune thanks to a dedicated silicon

With this instructable, I try to solve a problem everyone has: Passwords. Accounts. Logins. All the stuff you need to get into your favourite social media site, shopping site, blog or forum (they still exist, huh?). Now, there are several ways to control your accounts: Use always the same credentials: No. Never ever do that.

Digilent recently released a new FPGA development board. The Arty board. The Arty is designed to be used exclusively with Xilinx Vivado, and designed specifically for use with microblaze. This tutorial covers how to use the out of he box design that ships loaded into Arty’s Quad-SPI Flash, with I/O and UART. To view the

With summer arriving, and the fear of dried out chicken looming, we wanted a more high tech way to track the temperature of items we are grilling outside. There are wireless probe thermometers, but they require carrying around a separate readout. We wanted a way to read the termperature from our smartphone, so we took

I’ve played with the Intel Galileo a lot lately, so now it’s time to build some Intel Galileo projects! In this project I built a very simple weather station that records the temperature and humidity and saves these to a memory card. I’ll show you how to read temperature and humidity from a DHT11 sensor
