The open hardware innovation platform Seeedstudio produces the MDBT42Q, a Bluetooth Low Energy (BLE) module. It is a BT 4.0, BT 4.1 and BT 4.2 module designed based on Nordic nRF52832 SoC, a powerful, highly flexible ultra-low power multiprotocol SoC ideally suited for Bluetooth low...

Researcher at Harvard University had been working to build new microphysiological systems (MPS), also known as organs-on-chips, that can mimic the operation of the structure and function of native tissue. By developing such systems, they are replacing the conventional way of measuring...

Lithium-ion batteries are very popular as they're lightweight and have high energy density. But at the same time, li-ion batteries are very sensitive to overcharge/over discharge. An internal short circuit can cause fire and it may even lead to a violent explosion. Fortunately,...

New range of building blocks for IoT development are just out there! Just like LEGO, PUREmodules by Pure Engineering are the building blocks for IoT connected smart sensors where there is no need to solder, using breadboard or wires. It’s all done just by snapping the modules together...

A wide input range of 4.5 V to 40 V enables the TS3004x series of DC/DC synchronous buck regulators from Semtech to work in a wide range of applications, including industrial, telecommunication, and consumer. The current-mode TS30041 and TS30042 furnish 1 mA and 2 mA of continuous...

The Canadian Kron Technologies, led by its founder David Kronstein, has just launched a brand-new camera: Chronos. Chronos 1.4 is a purpose-designed, professional high-speed camera. It enables you to capture stunning high-speed video at up to 1280x1024 resolution thanks to its 1.4...
