by Julien Happich @ edn-europe.com: Part of the Swatch group, EM Microelectronic announced what the company believes to be the world's smallest Bluetooth chip. Offered in a 4x4mm QFN-28 package, in a WLCSP-21 or as a bare-die, the EM9304 is optimized for Bluetooth v4.2 low energy...

by Eric Bogers @ elektormagazine.com: Researchers from the Stanford University School of Medicine, using a combination of microfluidics, electronics and a standard inkjet printer, have succeeded in producing a biochip that can be used for research or diagnostic purposes. The...

Bob tipped us about a simple oscillator that uses negative resistance: Normally -according to the Ohm's law- when the applied voltage is increasing, the current is increasing too, however some components can break this law. When the voltage increases, current decreases. This is...

Mobile Roaming allows you to stay connected wherever you are and receive calls and SMSs, but with very expensive cost. So if you don’t have enough budget, you will lose your incoming calls till you are back from a travel. A team of innovators from Egypt had developed a new device...

The Pixel is an Arduino-compatible smart display, combining a 32-bit Cortex M0+ MCU with 32K of RAM, a 1.5" 128x128 color OLED screen, and a microSD slot all in one package. This is Rabid Prototypes’ second iteration of Pixel, which originally raised nearly $10,000 on Kickstarter...

In this video Circuit Basics show us how to use I2C to connect an LCD to the Raspberry Pi. After showing you how to connect the LCD to the Pi with a PCF8574 (http://www.circuitbasics.com/pj6v), they show you how to program it. First I'll cover the basic stuff like printing text to the...

In this technical tutorial Kolban Technical Tutorials start to look a Pulse Width Modulation with the ESP32 for dimming LEDs and for controlling a servo. ESP32 and Pulse Width Modulation -...

Susan Nordyk @ edn.com writes: Small enough for wearable devices, STMicroelectronics’ LIS2DW12 three-axis accelerometer draws only 50 nA in standby mode and 380 nA in low-power mode at a 1.6-Hz output data rate, adding negligible load on the battery. Operating from a supply voltage...
