by Jan Buiting @ elektormagazine.com: Confirmed last Monday (18 July 2016): 100%-thinkware-firm-and-brilliant-bunch-of-Cambridge-mathematicians/computer-scientists, ARM, is to be bought by Japan's Softbank for £24 bn ($32 bn). In official words: the board of ARM is expected to...

by Guillermo Jaquenod @ edn.com Actual microcontrollers have powerful bidirectional I/O ports, and you can use different techniques to fully exploit such capabilities. Recent Design Ideas described the “Charlieplexing” method as an effective way to drive M=N×(N–1) LEDs using...

Tahmid built a TV tuner IR remote with a PIC16F684: I then proceeded to write an IR transmitter using the PIC16F684 (using the MPLAB X IDE and XC8 compiler), following the timing information from the extended NEC protocol. In order to connect all the keys, I connected them in...

Florian Wolters made his own version of MMDVM adapter: During experiments with digital voice mode in hamradio I discovered a nice project describing an adapter for D-Star, DMR and other digital modes based on an Arduino Due and a little PCB to be put on top. This unit is called the...

Murata’s UMAL is a low-profile high capacity energy device. Designed to meet the demand for a slim high capacity energy source with a maintenance-free extended life cycle in wireless sensor nodes, the UMAL has charge/discharge and life-cycle characteristics superior to conventional...

Jon Roman and Donald Schelle have a design idea on how to simulate a high power led to test your driver circuit. Testing the driver circuit using LEDs, although easy, yields only typical results because the tests don’t factor in worst-case LED parameters and often generate...

This SMPS can be powered with low input voltage, from 5 VDC to 15 VDC and provided adjustable Output Voltage: + 92 Vdc to +340 Vdc. Can be used too, as power supply, for the Xenon Lamp, Nixie tube Clock, VFD display, Magic Eye, Neon, and too many others electronics circuits who need...

In this Instructable, you will learn how easy it is to send and receive SMS messages over GSM with Arduino. One of the essential elements of building IoT project is the ability to connect devices. Wi-Fi and Bluetooth are good low cost choices, but they work only at close ranges, or...
