Q: Jon, Breadbords generate lots of nosie, any other way recommand?
A: Yes, they do, and for analog circuits, the capacitance between contacts can cause problems. To reduce noise and capacitance use the "dead bug" prototype approach. Ren a Google image search for "dead bug prototype" (without the quotes). One of my colleagues used 10-megohm resistors soldered to a copper PCB ground plane and binding posts (the ungrounded end) and built a circuit from resistor to resistor. Analog expect Bob Pease at National Semiconductor (now TI) used this technique a lot.
By experimenting with the photovoltaic reaction in solar cells, researchers at MIT have made a breakthrough in energy efficiency that significantly pushes the boundaries of current commercial cells on the market.
In a world that's going green, industrial operations have a problem: Their processes involve materials that are potentially toxic, flammable, corrosive, or reactive. If improperly managed, this can precipitate dangerous health and environmental consequences.
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
