Previously I have blogged about using relays with an Arduino, and SainSmart relays specifically. A while back I received a 4 relay, and a 8 relay board, and both of them used negative logic, i.e. a LOW activated them, and a HIGH deactivated them.
The Onion Omega, a promising open hardware development platform, blew through its Kickstarter goal this week, where its promise to make hardware development easy for software developers seemed to resonate with backers.
This home automation box allows the maker to turn on or off the lights in a room or select color of a hacked oil diffuser, project the indoor or outdoor temperature and humidity ratings from an arduino node by using RF transmission 433Mhz or create...
The release of the second generation Raspberry Pi has made the concept of running a cluster of Raspberry Pi's much more sensible vs. a cluster of first generation Pi's. The University of Southampton built a cluster of 64 Raspberry Pi's. [IridisPi]The Iridis Pi has a peak CPU performance benchmark was around 1 GIGAFLOPS (floating point operations per second)
