Debian on DragonBoard 410c Development Board

I purchased Qualcomm DragonBoard 410c development board last year, and first tested it and run some benchmark on the 96Boards compliant hardware with Android. I found that it was still work-in-progress, and decided to wait before trying Debian on the board. I’ve now done so, and will report by experience installing Debian Linux, playing with the board, and running Phoronix benchmarks to compare it to other ARM Linux boards. Installing Debian on DragonBoard 410c The first challenge is to navigate through the documentation that is not always clear or up-to-date. I eventually ended up on DragonBoard 410c Wiki on Github. You then have to decided which image you want. While there are two official operating systems with Android and Debian, you can three “entities” releasiong their own images. For Debian specifically, you have the Linaro image, and Reference Platform Build (RPB) image. I could not find any changelog or known […]

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 […]
