I agree, Chuck. Like many of the Sherlock Ohms blogs, it's hard to imagine how they figured out such an off-the-wall solution. It is certainly not intuitive. The trick here was remembering something odd from the past.
This is what I love about the Sherlock Ohms postings. You can turn the equipment upsidedown to find the problem, but in the end, it was a line that had to be drawn darker. This is a common solution to difficult problems -- look at what was difficult at an earlier stage in the equipment's development.
As energy efficiency becomes more and more a concern for makers of electronics devices, researchers are coming up with new ways to harvest energy from sound vibration, footsteps, and even electromagnetic fields in the air.
The government wants to study your brain, and DARPA wants to use similar information to give robots true autonomy beyond any artificial intelligence developed to date. Sound like science fiction? It's not.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
