Cycle related gadgets are always of interest to Gadget Master, so I was interested to see an article on New Scientist about a “vibrobelt”, described as “sat nav for your waist”. Basically, it’s a belt to help guide cyclists, with actuators indicating the relative direction to take – left, right, and forwards

bonybrown.blogspot.gr writes: SMD solder paste stencils are used to accurately “print” a thin layer of solder paste onto a PCB on which the components are placed before reflow soldering. The “printing” is done in a method similar to screen printing, where the solder paste is squeegeed through a 4 mil thick, stainless steel stencil onto the PCB

After the recently introduced 1A diode SKL14, we introduce you the 3A type in the same miniature PowerSOD-123T package. New Schottky diode SKL34 features almost the same possibilities of usage like SKL14, which was recently introduced in our article: SKL14 – 1A Schottky diode will fit everywhere
SKL34 – another surprisingly small 3A Schottky diode Read More »
With the new AIR 40 wind turbine it is possible to gain 40 kWh monthly – easily and safely. Advantages / Features: high quality wind turbine with 12, 24 or 48V output voltage 40 kWh monthly at an average wind speed of 5.8 m/sec operation at 3.1-22 m/s wind speeds microprocessor based controller aluminium body composite blades optimized for a quiet operation 1.17m rotor diameter electronic overspeed protection brushless alternator (dynamo) with a long lifetime Small wind turbines are an excellent electric energy source for all „off-grid“ applications with a low and middle power consumption like telecommunications, lighting, SCADA (telemetry) and other.

(Phys.org)—Today’s dismounted warfighter can be saddled with more than 100 pounds of gear, resulting in physical strain, fatigue and degraded performance. Reducing the load on dismounted warfighters has become a major point of emphasis for defense research and development, because the increasing weight of individual equipment has a negative impact on warfighter readiness.
(Phys.org)—Internet, computing and networking technologies are now integral to many people’s lives, generating ever-increasing amounts of digital information. Data storage experts estimate that by 2020, 35 zettabytes—35 x 1021 bytes—of digital information will require storage that is safe, reliable and above all, quickly accessible
