How to use this When the simulator starts up you will see an animated schematic of a simple LRC circuit. The green colour indicates positive voltage. The grey colour indicates ground. A red colour indicates negative voltage. The moving yellow dots indicate current. To turn a switch on or off, just click on it. If […]
ARM’s acquisition of Wicentric and Sunrise Micro Devices has produced the Cordio family of standards-based, sub-volt, radio IP supporting Bluetooth Low Energy. Each Cordio product includes a pre-qualified, self-contained radio block, related link layer firmware, stack and profiles along with guidelines for design, test, integration, qualification, and application development.Cordio aims at ease of integration and delivery

An article by Dieter Laues in the February 2012 issue of Elektor inspired me to get my soldering iron out. The article described how by measuring the frequency of the mains electricity supply in any socket, the relative load across the entire electricity network could be determined. I ordered a pre-programmed processor (of the correct

Linear Voltage Regulator The power supply runs on a linear voltage regulator built on discrete components. The design of the linear regulator was inspired by the user Amspire from the EEVblog forum. The basic idea is that the Q1 pass transistor and U5A op amp act in a classic voltage regulating loop. U5A gets feedback

Aiming at lighting manufacturers that don’t want to buy a soldering line, Sheffield-based Litecool has developed a self-adhesive self-connecting LED package that can be pick-and-placed direct onto heatsinks – and it accepts standard lenses from Carclo. No PCB, metal-cored or otherwise, is required. The key to self-adhesive packaging for power devices is to spread heat

BEAVERTON, Ore., March 15, 2016 /PRNewswire/ — Tektronix, Inc., the world’s leading manufacturer of oscilloscopes, today introduced the P7700 series of TriMode™ probes for use with Tektronix performance oscilloscopes. Offering up to 20 GHz bandwidth, the new probes ease the challenges designers face when debugging circuits found in the latest mobile and enterprise designs by minimizing
17.03.16 – EPFL scientists achieve the highest yet reproducibility for perovskite solar cells combined with a boundary-pushing 21.1% efficiency at normal operating conditions. Perovskite solar cells hold much promise for cost-effective solar energy. However, heat stability is an issue, and can significantly limit the solar cell’s long-term efficiency. A team of scientists led by Michael
