After having an entire month of dormancy on this blog, I’m finally beginning to cross off the blog posts on my “Pending” list. Last year, I made a blog post talking about Kentli’s lithium-ion based AA battery that has an internal 1.5 volt regulator. The first order never arrived, and the second one had arrived

By Stephen Evanczuk Contributed By Hearst Electronic Products 2014-12-17 For rapidly growing markets such as wearables or the Internet of Things (IoT), energy harvesting can significantly enhance battery life—or even enable battery-free designs. At the same time, however, engineers designing wearables and IoT devices face significant constraints in total design size and footprint. To meet

Wouldn’t it be ideal if you could just press ‘print’ to produce a printed circuit board? In a paper titled ‘Instant Inkjet Circuits: Lab-Based Inkjet Printing To Support Rapid Prototyping Of Ubicomp Devices’ researchers Yoshihiro Kawahara of the University of Tokyo, Steve Hodges of Microsoft Research and Benjamin Cook, Cheng Zhang and Gregory Abowd of

Diodes Incorporated introduced a pair of compact 40 V, 1 A-rated gate drivers specifically designed to control the high-current power MOSFETs used in onboard and embedded power supplies and motor drive circuits. Enabling the MOSFETs to be more rapidly and fully switched on and off, the ZXGD3009E6 (SOT26 package) and ZXGD3009DY (SOT363 package) help minimize

A new way of switching the magnetic properties of a material using just a small applied voltage could signal the beginning of a new family of materials with a variety of switchable properties, according to a team of MIT-based researchers. The technique could let a small electrical signal change materials’ electrical, thermal, and optical characteristics.

Active analog filters can be found in almost every electronic circuit. Audio systems use filters for frequency-band limit ing and equalization. Designers of communication systems use filters for tuning specific frequencies and eliminating others. To attenuate high-frequency signals, every data- acquisition system has either an anti-aliasing (low-pass) filter before the analog-to-digital converter (ADC) or an

It has been quite some time since my last post – as often happens, life intervenes and this time just a bit too much hospital time both for myself and one of my kids. Things are good now and normal can resume… LED Driver For years I have had this Black&Decker Firestorm FSL18 flashlight, but
