Researchers at Tohoku University in Japan have developed a new low-cost flat panel light source that could pioneer a new generation of brighter, cheaper and greener lighting devices to rival LEDs. The device uses arrays of highly conductive carbon nanotubes to deliver evenly-distributed illumination with high efficiency and a power consumption as low as 0.1
Cheap, ultra low-power light source runs on just 0.1 Watts Continue Reading
Modular DC-DC switching voltage converters (or voltage regulators) are fully integrated devices that take away most of the complexity of power supply design — but not all. One of the key areas that are still left to the design engineer’s discretion is the choice of components for, and layout of, the energy storage and filtering
Capacitor Selection is Key to Good Voltage Regulator Design Continue Reading
3.5″ Embedded SBC with Intel® Celeron® Processor J1900/J1800, LVDS, VGA, DisplayPort, Three GbE LANs and Audio. CAPA84R, is a fanless 3.5-inch embedded motherboard powered by the Intel® Celeron® processor J1900 quad-core or J1800 dual-core. The CPU is located at the rear side of the motherboard, which further aids the heat-extraction process and simplifies maintenance procedures.

The power saving mode here is what sets this Instructable apart from other examples showing day of the week, month, day of the month, time, humidity, and temperature. It is this capability that allows this project to be run from a battery, without the requirement for a “wall wart”. I had posted an earlier Instructable,

A while back I built a simple constant current electronic load using an aluminum HDD cooler case as the heatsink. While it was sufficient for a few amps’ load under low voltages, it could not handle load much higher than a few dozen watts at least not for a prolonged period of time. So this time around,

How to build your own VGA-adapter My lifetime project: building an 8-bit computer using Z80 CPU. This week I had a bad flu and could not do anything useful so I decided to dig up my old plans for this project. I first re-designed many things, like power, CPU-board, IO-board and so on (my old

Using a hybrid silica sol-gel material and self-assembled monolayers of a common fatty acid, researchers have developed a new capacitor dielectric material that provides an electrical energy storage capacity rivaling certain batteries, with both a high energy density and high power density. If the material can be scaled up from laboratory samples, devices made from
Sol-gel Capacitor Dielectric Offers Record-high Energy Storage Continue Reading
