Hyper Efficient Audio – 100 W from a single battery!
It’s amazing what application specific integrated circuits can do now. I never stop being surprised at what I keep seeing coming out of the pipeline. Audium Semiconductor recently gave me one such surprise with the hyper efficient AS1001 amplifier that can deliver 100 watts peak power, from a 1.5 volt (read single battery) power supply.

Driving the Nissan Leaf
The Nissan Leaf is an all electric car for the masses. On paper, the car seems to be a much more realistic proposition than cars like the Tesla or the Fisker. It’s a small 5 seat car, with a range of 100 miles and a target price somewhere a bit above $25k. For many, this is a price point that is manageable, even in these tough times. Continue Reading >>
How do you keep bits secure?
Let’s say you have a 256 bit encryption key in some piece of hardware. How do you keep it secure? Turns out, it’s very, very hard. Especially when the actual device can be in the hands of those that want to crack it. Continue Reading >>
Automotive Gas Turbines – Then & Now
I was reading about a new serial hybrid that uses a micro-turbine, and that got me looking at automotive turbines of the past. We’ve come a long way, baby! Continue Reading >>
Battery fill up via pump?
Turns out the crafty Germans are at it again! As reported in the Fraunhofer Research News recently, a group there is working with something called a redox flow battery. Basically it uses a liquid instead of a solid to store the charge. This isn’t new, but the team has brought the energy density up to that of Li-Ion batteries, and that is new! Continue Reading >>
