by Graham Prophet @ edn-europe.com: Belgian researchers from imec, at a conference** dedicated to compound semiconductor technology, are to present promising device results with a InGaAs-only TFET (tunnel field-effect transistor) that achieves a sub-60 mV/decade sub-threshold swing at...

by Mahesh Venkitachalam @ hackaday.io: I use 9 V batteries for a prototyping a lot of my electronics projects. I was inspired by the Sparkfun breadboard power supply board, and wanted to create something similar, but with a more convenient form factor for use with a 9V battery. The...

Five years ago (on 29 February 2012, to be exact) the original Raspberry Pi was unveiled – on this celebrated first day the available stock was sold out within a few minutes, more than 100,000 boards were ordered and the Farnell and RS Components web stores where down for while because...

PCB-Investigator is a CAD software developed by EasyLogix for circuit board design and PCB quality assurance. Its latest version came earlier in February with a new browser interface that enables electronics assemblers to do PCB review processes without the need for local...

The LTM9100 μModule is an all-in-one solution for controlling, protecting, and monitoring high voltage power supplies up to 1000VDC. A 5kVRMS galvanic isolation barrier separates the digital interface from the switch controller, driving an external N-channel MOSFET or IGBT switch....

by bekathwia @ instructables.com: I was inspired by the Play Button awards YouTube sends out for subscriber milestones and whipped up a simple circuit using an ESP8266 wifi board and seven segment display to show off my realtime subscriber count. This is a great IoT beginner...
