I feel very fortunate to have gotten to jump right into board design right out of school, which I can't believe was so long ago. The first 6 years of my career was a trial by fire that taught me a lot of great lessons on design practice. To this day I still make recommendations on designs based on what I learned about designing in plenty of operational margin and saving cost wherever you can. Yes those things don't really go together, but the point is I never take for granted the value inherent ...
Inspired by Using a DC-DC Isolator to allow single power input to case? (and to stop hijacking that post) I'm checking the output noise of a Traco Power DC-DC converter. The  device I have is the TEN 6-4822WIN. It translates 48 V into +- 12 V. In this post, I'm using its +12 V to power my dc load in two situations: with and without fan.       I'm using a very naive approach, directly using the switcher output to power an analog circuit and the fan. And virtually no outpu ...
Governments around the world are more and more open to electric cars as a viable way to reduce their countries’ CO2 production; but the benefits are still controversial. (Image credit: from vectorstock.com)   Nobody knows the exact time humanity started to worry about the environment. Some people even don’t think there is much to worry about. However, we can all see that technology has embraced the challenge of finding or creating “cleaner” sources of energy. While ...
The device could capture terahertz waves and convert it to DC current, which could power-up electronic devices. (Image Credit: José-Luis Olivares, MIT)   Physicists at MIT have achieved a new scientific breakthrough that could one day allow household devices to be powered-up by direct current produced from terahertz waves. A terahertz wave, which is emitted by any device that sends out Wi-Fi signals, is an electromagnetic wave with a frequency between microwaves and infrared light. ...
BlueWave Solar is currently working on installing solar panels that won’t take over cropland on farms. Solar energy could help improve farming, but there are some challenges to overcome first. (Image credit: Dennis Schroeder, NREL)   As the demand for renewable energy increases, farmers are looking for new ways to make their own farms greener. Solar panels are a popular option, and while it’s not uncommon, they come with their own set of challenges. You don’t want the pan ...
The ClearView Power windows are coated with an extremely thin layer of organic dye that absorbs infrared and ultraviolet light and converts it into electricity to power buildings. (Image Credit: Ubiquitous Energy)   Another day, another solar window. What if windows in our homes or office buildings could generate electricity from the sun? Ubiquitous Energy, a Redwood City, California-based start-up company, has developed ClearView Power windows with built-in transparent solar cells that ca ...
