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...

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...

Three-axis MEMS accelerometers, Analog Devices’ ADXL354 and ADXL355 perform high-resolution vibration measurement to enable the early detection of structural defects via wireless sensor networks. The low power consumption of the devices lengthens battery life and reduces the time...

Infineon Technologies' Infineon Designer, introduced at the 2016 electronica trade fair, is presented as the first online prototyping engine combining analogue and digital simulation functionalities in an internet application. By Graham Prophet@ edn.com: Requiring a web browser only,...

Configurable as quad, triple, dual or single output, the LTM4643 quad output step-down µModule [micromodule] (power module) regulator deliver, respectively, 12A, 6A & 6A or 9A & 3A, or 4 x 3A from a 9 x 15 x 1.82 mm ultrathin LGA package. by Graham Prophet @ edn.com: This...
