Thread was announced about two years ago, as a new IP-based wireless protocol based on 6LoWPAN and 802.15.4 standards and targeting IoT applications. Nest Labs, an Alphabet company, has now released OpenThread open-source implementation of the networking protocol under a BSD license. The source code (C++) for OpenThread includes supports for End Device, Router, Leader & Border Router roles, and can be found on Github. The implementation is said to be OS and platform agnostic with a radio abstraction layer, have a small footprint, and implement all Thread networking layers, namely IPv6, 6LoWPAN, IEEE 802.15.4 with MAC security, Mesh Link Establishment, and Mesh Routing. To quickly get started, you may want to read the Examples README which explains how to build the code, start two nodes, and ping them. Interestingly, while the code is there for everybody to use, only paid members ($2,500 to $100,00) of the Thread group can […]

Tacterion Brings Capacitive Touch to Smart Clothing and Various Materials or Surfaces
With the advance of smartphones and other mobile devices, we’ve all been used to capacitive touch screens, but Tacterion, a German company born out of the Institute of Robotics and Mechatronics, at the German Aerospace Center, has designed “artificial skin” sensors that bring capacitive touch and other features to all sort of materials. Since the company wants to protect its IP they don’t disclosed much details about the inner working of their sensors: The patent protected technology is completely polymer-based. The technological principle are sensitive elements that measure based on transition resistivity: The more pressure is exerted on the polymer-based, electrically conducting elements, the lower the transition resistivity is, which is being measured continuously. Using our highly integrated high-speed readout electronics, a matrix of sensor elements can be combined to form sensitive surfaces. The readout electronics provides information regarding pressure and its distribution at a frame rate of 400 Hz. […]

Electrodragon WiFi IoT Relay Includes ESP8266 Module, AC Power, and Enclosure for $6
Thanks to ESP8266, the cost of WiFi relays has dramatically come down, but so far, I could not find an all-in-one solution with ESP8266, relay, AC power and enclosure, and for example I’m still using NodeMCU board, a relay board, a USB power supply, and put all that into a plastic jar in order to control a water pump. It works but it’s not ideal, and solutions like Wemos D1 mini with relay shield improves things further, but Electrodragon has come with a connect-and-play WiFi IoT relay that integrates everything including the case for $6 + shipping. Wifi IoT Relay Board Based on ESP8266: WiFi module – ESP-12F based on Espressif ESP8266EX WiSoC Relays – 2x Songle SRD-05VDC-SL-C relays supporting 125VAC/10A, 250VAC/10A, 30VDC/10A, 28VDC/10A Input/Output – 3x terminal blocks for relay and power Expansion – 12-pin header with Rx/Tx, GPIO4, Btn2, GPIO15, 5V/GND, ADC, GPIO5, Btn1, OUTPUT1, and 3V3 Debugging […]
