Teardown: D-Rex toy dinosaur
The D-Rex is billed as a ferocious yet loyal dinosaur robot with an independent personality. The toy combines robotics, interactive sensors and reptilian-like skin. He walks, follow the sound of your voice and makes funny noises. Weighing in at about 8.5 lbs, D-Rex stands a little less than two feet high. You interact with D-Rex […]
EV advances come from Formula E electric racing
You may thank Formula E electric racing technology for some of the advances that ultimately make electric vehicles practical on ordinary highways. Just as automakers have sponsored racing programs to help perfect advances in conventional automotive technology, electronics makers are taking the same approach with Formula E racers to get a jump on components for […]
Researchers find ways to integrate GaN power circuits onto ICs
This year’s IEEE International Electron Devices Meeting (December 7-11, 2019) played host to presentations describing advances in gallium-nitride technology that may lead to smaller, more integrated power circuitry such as single-chip switching power supplies and more efficient power transistors. The IEDM is considered one of the premier technical conferences for developments in semiconductor and integrated […]
What do molded power inductors bring to high efficiency, compact designs?
Modern hardware applications trend towards compact designs that are power efficient. Passive devices don’t get as much attention as a microcontroller’s many sleep and shutdown states. However, every drop of available efficiency adds up and can make a difference. It’s possible to improve power efficiency with the right inductor. Power inductors are a necessary component […]

E-plane maker bets LiS battery technology could double the range of electric-powered flight
The best commercial lithium-ion batteries today deliver energy densities of around 250 Wh/kg. But battery chemistry oriented around lithium-sulfur could deliver double that figure. This potential improvement has brought electric plane-maker Bye Aerospace in Colorado to work with UK-based Oxis Energy on LiS cells able to provide in excess of 500 Wh/kg at 20-Ah capacity. […]
Better battery management: New technique measures electrochemical impedance of multi-cell stacked lithium-ion batteries
Researchers at Panasonic Corp. and Ritsumeikan University say they have developed a new battery management technology that measures a battery’s electrochemical impedance, which is an effective method of evaluating the residual energy of lithium-ion batteries in use. The technique is expected to be applied in applications characterized by numerous battery cells stack in series. Panasonic […]
Selecting a replacement external power supply – what you need to know
Fundamentally, you need to know four basic things when selecting a new power supply for a broken electronics device. The voltage coming from the socket at the wall (Europe/Japan/US), the voltage output, the current, and the type of connector (USB Type-B mini, barrel, USB-C). What most of us don’t know is that there are some […]
