Maker William Sun Petrus has created an awesome drum machine using a 1920’s Remington compact typewriter combined with a little Arduino hardware and programming. The processing power is provided by an Arduino Mega and software used includes Ableton, Loop Midi and Hairless Midi Serial. Check out the video below to learn more and see the […]

Mythological legend has it that Tempestas, the Roman goddess of storms and sudden weather, saved the consul Scipio when his fleet of ships got caught in a storm off of Corsica. In return, she demanded that a temple be dedicated to her. [SephenDeVos]’ beautiful barometer, dubbed Tempestas II, demands nothing of the viewer, but will likely

The Micro Maestro is the first of Pololu’s second-generation USB servo controllers. The board supports three control methods — USB for direct connection to a PC, TTL serial for use with embedded systems, and internal scripting for self-contained, host controller-free applications — and channels that can be configured as servo outputs for use with radio

It’s wasn’t so long ago that RC transmitters, at least ones worth owning, were expensive pieces of gear. Even more recently than that, the idea of an RC transmitter running an open source firmware would have been considered a pipe dream. Yet today buying cheap imported transmitters and flashing a community developed firmware (if it

The SLF3S-1300F liquid flow sensor is based on Sensirion’s proven CMOSens® Technology and optimizes costs by simplifying the design without sacrificing the easy fluidic, electrical and mechanical connections. The straight and unobstructed flow channel has no moving parts; inert wetted materials provide outstanding chemical resistance and excellent media compatibility. In measuring flow rates up to
Sensirion Announces Its New Liquid Flow Sensor – SLF3S-1300F Continue Reading
At last week’s IEEE International Electron Devices Meeting (IEDM) in San Francisco (USA), imec, the world-leading research and innovation hub in nano-electronics and digital technology and Holst Centre debuted a miniaturized sensor that simultaneously determines pH and chloride (Cl-)levels in fluid. This innovation is a must have for accurate long-term measurement of ion concentrations in
