Most of hardware developers have used a temperature sensor in one or more of theirs projects. There are many types of temperature sensors, such as LM35, thermistors, and resistance thermometers. These types differ in response speed, temperature ranges, accuracy, and other...

PragmatIC is a world leader in manufacturing ultra low cost flexible electronics enabling the potential for trillions of “smart objects” that can interact with their environment. It has developed a unique platform of patented technologies to design and manufacture flexible...

Jarek tipped us with his latest project, an E-paper screen shield kit for Teensy. He writes: E-paper screens have been hacked out of Kindles and store price tags for a while, but this is the first ( to my knowledge ) open-source project which offers a simple and cheap interface for...

Maxim Integrated has posted details of the MAX30205 temperature sensor for thermometer applications. The sensor accurately measures temperature and provide an overtemperature alarm/interrupt/shutdown output. by Graham Prophet @ edn.com The chip converts the temperature...

Silicon Labs, the leader in energy-friendly solutions for a smarter, more connected world, has been constantly making silicon, software and tools to help engineers transform industries and improve lives since 1996. Silicon Labs has just launched its newest development platform, The...

A new prototype of a lithium-sulphur battery – which could have five times the energy density of a typical lithium-ion battery – overcomes one of the key hurdles preventing their commercial development by mimicking the structure of the cells which allow us to absorb nutrients. @...

ray @ rayshobby.net build a wifi enabled color led matrix using ESP8266. He writes: Last Thursday I had a lot of fun doing a workshop at my college (UMass Amherst) where I taught students to use a WiFi-enabled Color LED matrix combined with Javascript programs to create animations...

Giovanni Carrera writes: The purpose of this project is to provide a 4-20 mA output from a PWM signal generated by a microcontroller ATmega328 and numerous other chips, such as the PIC. One of the more interesting applications of this circuit would be to replace or to realize a smart...
