A solid state relay (SSR) is an industrial component used for interfacing low voltage control signals to high current mains voltage loads. The SSR may be designed to switch either AC or DC to the load. It serves the same function as an electromechanical relay, but has no moving parts. You can control SSRs easily →

Stripboard is the generic name (also known as Veroboard) for a widely used type of electronics prototyping board characterized by a 0.1 inch (2.54 mm) regular (rectangular) grid of holes, with wide parallel strips of copper cladding running in one direction all the way across one side of the board. Stripboard is available from many vendors. Stripboards →

Every now and then situation arises where you need to construct simple filter circuits. Usually a low pass circuit is the most often needed one. A low-pass filter is a filter that passes signals with a frequency lower than a certain cutoff frequency and attenuates signals with frequencies higher than the cutoff frequency. Low-pass filters →
Wired is writing about The Chinese firm accelerating hardware, not software at http://www.wired.co.uk/magazine/archive/2016/04/features/hax-hardware-accelerator-china In four years, HAX has invested in 100 companies after vetting what general partner Benjamin Joffe says are 1,000 startups a year. “It’s an investment company that functions as a hardware accelerator,” explains Joffe. “We help them manufacture at scale. Then →
No matter how efficient we make our transistors and memory cells, they will always consume a fixed but tiny amount of energy set by the second law of thermodynamics, a new study suggests. Now the question is how close our real-world devices can get to this fundamental value. “At the end of the day, it confirms that Landauer’s theory seems to →
