Boris Landoni @ open-electronics.org presents his 32bit Arduino Compatible board which has some nice features on board. He wrties: Our prototyping board acquires a 32-bit processor and sets the bar high, towards demanding applications that may take full advantage of the WiFi...

Chip McClelland @ hackster.io published his solar li-po battery charger based on MCP73871 to manage the solar and DC charging of the LiPo battery, TPS63020 Buck-Boost Converter and Maxim 74043 LiPo Fuel Gauge. He writes: I build connected sensor which are often deployed in local...

Researchers from Nanyang Technological University in Singapore build a new type of flexible supercapacitor that aims to be used in wearables and other portable electronics such as T-shirts charging mobile phones. The new type of capacitor is made with out-of-plane wavy structures of...

ePaper displays  (EPDs) are becoming a trend in application, just like the display used in Amazon Kindle,  for their low power consumption due to the  to the underlying ‘bistable’ display technology. These displays can continue to show information without any power at all. It is...

Michael Dunn @ edn.com did a quick tear-down of his drone. The main processor is an ST STM32F031K6, an ARM Cortex-M0 with the usual cadre of peripherals, as well as a motor-control block (the leftmost large chip in Figure 2). Although at the lower end of the ARM continuum, it’s...
