Qualcomm Tricorder XPRIZE Selects Two Winners for Commercial Medical Tricorders

Healthcare takes around 10% of worldwide GDP, and while in some cases an increase in the healthcare to GDP ratio means better care for people, in other cases it may lead to a decrease in the population’s living standards. There are political, business, and legal issues involved in the costs, but overtime I’m confident that technology can both improve care and lower the costs, in some instances dramatically, especially if open source designs become more common, and there’s some work in that respect with open source projects for prosthetics, opthalmoscope, and even surgical robots. Some commercial projects also aim(ed) to lower the costs of diagnosis tools such as Sia Lab’s medical lab dongle or Scanadu medical tricorder. The latter project sadly did not manage to pass FDA approval, and the company will stop supporting it on May 15, 2017, but that does not mean others have given up on developing […]

ESP8266, Mongoose OS & Grove Sensors – An Alternative Solution for Hackathons

CNXSoft: This is a guest post by Cesanta If you walked into any Hardware hackathon over the last year, you would see they are about innovation and bringing new ideas to this world and most of them are centered around the connected devices nowadays. However, just walk the floor, talk to the teams and you can quickly see an elephant in the room. The Hackathons are about connected devices, but with the ‘recommended’ and frequently sponsored hardware distributed to the teams such as Intel Galileo, Raspberry Pi, etc…. developers may struggle for a long time to even connect it to the cloud! Not to mention the innovation is usually hindered by a tedious environment setup which takes hours, things to learn about the specific hardware and how it can be programmed using low level languages. So many teams spent most of the time fighting with those issues and oftentimes still […]

Karl’s Home Automation Project – Part 3: Adding Light Detection to a Motion Sensor

This is the 3rd part of my Home Automation light project. In the first part, I wrote about basic setup with basic Sonoff Wifi MQTT switches and setting them up. In the second one, we added some 433 MHz motion sensors and a 433 MHz to MQTT bridge. And finally in part 3, we are going to modify the 433 MHz motion sensors to only work when it is dark in the room. Motion Sensor The motion sensor I linked in part 2 is run by a common chip called a BISS0001. We are interested in pin 9. If voltage is below .2v it will not trigger a motion. This solves the problem discussed in part 2, when we have a gloomy day or if blinds are closed etc. By adding an GL5537 LDR (Light Dependent Resistor) shown as R3 in the diagram above, you will achieve the desired effect.

NanoPi NEO2 Board, NanoHats, and BakeBit Starter Kit Review – Part 1: Hardware Overview & Assembly

NanoPi NEO 2 development board is an update of NanoPi NEO with a quad core 64-bit Allwinner H5 processor + 512 MB RAM, Gigabit Ethernet, and an extra audio header, which can be a great little board for headless application since there’s no video output. FriendlyELEC ask me whether I wanted to review to board with some of their NanoHATs add-on boards, and while I asked for NanoHat PCM5102A audio board and NEO Hub which I intended to use with Grove modules from my Wio Link Started Kit, I get a bit more than expected, as the company included sets of NEO 2 boards and accessories, NanoHATs, two serial debug board, and their BakeBit Starter Kit with several Grove modules to play with. Since I have so many things to look at in this first post, I’ll just describe the hardware, assemble it, quickly check the paper documentation, and give […]
