My guess is that the button switches did not use silver, since that material is "expensive", but rather some much cheaper substitute. Many times, after a product is designed it gets it's bom cost reduced, often by people with only an accounting degree, and having all the engineering skills that an accounting major study provides. So the expensive switch gets replaced by one using electroless tin, which is cheaper. Of course the pull up (or pull down) resistors may not be in spec either, ading to the complication.
Actually, I am now having push button panel problems on my relatively new dishwasher, which the membrane assembly does not want to continue to sick to the control panel, My guess is that the really good adhesive would have added a cent to the cost of the dishwasher.
That slogan goes " Never Time to DO IT RIGHT, Always time to do it over". I once worked for a company that was often in a rush to do things before they knew what to do. The result was often a lot of expensive scrap. That organization is no longer in business, by the way.
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
