Though it may be a late response, a number of electronic industry experts are questioning the scientific reasoning behind the European Union's (EU) Restriction of Hazardous Substances (RoHS). Those speaking out against the legislation claim the EU did not base the directive on robust science. They point to a recent study that shows the conversion to lead-free solder actually runs contrary to the best interests of the environment.
Sources agreed that RoHS will not be repealed, and they concede that China and the U.S. will go forward with their own legislation similar to RoHS. But they still raised the issue that RoHS is based on faulty assumptions about environmental damage. They note that RoHS was based on outdated concepts — such as lead leaching into the soil from discarded electronic products — that have since been proven scientifically wrong. RoHS dissenters have created a website called Pushback at www.Rohsusa.com to discuss their disputes with the science behind RoHS-style laws.
Two different shape-shifting polymers have been announced from two different universities: Wyss Institute at Harvard University and Zhejiang University in eastern China. Both of them change their shapes when immersed in water, and the one from Wyss Institute was made with 3D-printing techniques.
When you think of the DARPA Robotics Challenge, you may imagine complex humanoid contraptions made of metal and wires that move like a Terminator Series T-90. But what actually happened at the much-vaunted event was something just a bit different.
Traditional dev kits are based on a manufacturer’s microcontroller, radio module, or sensor device. The idea is to aid the design engineer in developing his or her own IoT prototype as quickly as possible. A not-so-traditional IoT development kit released by Bosch aims to simplify IoT prototyping even further.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
