The Wyland National Mayor’s Challenge for Water Conservation is presented by The Wyland Foundation and Toyota, with support from The Toro Company.
No drought relief yet, despite strong Sierra snowpack
The manual snow survey revealed a water content of 97% of historical average — a strong showing, but not strong enough to significantly alleviate the water deficits of the past four years of drought.
Measure the accuracy of Andy’s Android-friendly frequency counter
Head over to Andy Workshop for a wealth of Gadget Master material, including how he built his own frequency counter (originally looking for a simple tool for another project, he was side-tracked into building one himself). Thus began the “Nanocounter” (see right). “I somehow managed to persuade myself that it’d be a fun and educational project …

Glasgow researchers build “smartphone” gravity meter to measure volcanos
Scientists at the University of Glasgow have created a very low cost gravity meter which could be used to monitor volcanic activity using commercial MEMS device technology found as accelerometers in smartphones. The result they says is a sensitive detector capable of measuring minute changes in gravity, and at significantly lower cost than a traditional …

LED headlights score top, and bottom, in US tests
The US Insurance Institute for Highway Safety (IIHS) have assessed headlights on 31 ‘mid-sized’ cars and given only one of them a ‘good’ rating – a Toyota Prius with LED headlights. 82 cars were tested over all as some were tried with more than one headlight option. The rest were: ‘good’ (1 car) acceptable (11), …
IDT adds to power management portfolio
IDT has added to its power management products with the introduction of a dual-phase digital power controller that can help customers optimize, monitor and control high-power supply systems. The second-generation ZSPM1363 digital PWM controller delivers high performance and excellent transient response, making it ideal for addressing the growing demands in the telecommunications, server, storage, FPGA …
Electric vehicle cost penalty may be decisive
In the coming decades the improvement and choice of land vehicle powertrain will mainly be dictated by emissions conformance which will mean a cost/performance compromise. This will result in popularity moving from conventional to pure electric as laws tighten and technology improves, writes Dr Peter Harrop, chairman, IDTechEx Pure electric is already the norm for …
Platforms
I’ve never been quite sure what a ‘platform’ is. The word gets used a lot – in fact it’s in nearly every press release I see – but I’ve always thought it a bit like ‘ecosystem’ – vague, woolly and bolloxy. However now there’s a book out which explains the platform concept rather well. Called …
Smart clothing heats head and feet with a smartphone
A team of German thermal clothing designers have developed a way of controlling your body temperature using a smartphone app. Called Vulpés, the are offering the first thermo-regulating beanies and heated insoles on Kickstarter. Based in Lubeck, they have developed a mobile application to connect the Vulpés apparel to a smartphone which can be used …
Perovskite solar cells reveal another advantage
Solar cells made from lead-halide perovskite cells could be improved following the discovery that photons are recycled within them. Perovskites photo-voltaics are new and fast-improving which, according to Imperial College last year, rose in efficiency from less than four per cent in 2009 to over 20 per cent, on par with traditional solar cells. Now a …
