OBD-II dongles that you connect to your car’s OBD-II port have been around for several years, but they were initially simple devices with USB or Bluetooth connectivity that you control with your smartphone or computer. More recently we’ve seen more complex OBD-II head-up-diplays, and boards such as Macchina M2 open-source hardware OBD-II board that takes various XBee modules for 4G, Ethernet, WiFi, Bluetooth, GPS, and so on. iWave Systems, a company better known for their system-on-modules, has now unveiled their own OBD-II dongle with NXP i.MX 6UL processor running Linux, and integrating 4G LTE and GPS by default. iWave Systems OBD-II dongle specifications: Processor – NXP i.MX 6UL ARM Cortex-A7 processor @ 528/696MHz Memory – 256 MB DDR3 (Optionally upgradeable to higher capacity) Storage – 256 MB NAND Flash (optionally upgradeable to higher capacity). Connectivity – Built-in 4G Modem with antenna, optional WiFi & Bluetooth 4.0 LE module Positioning – […]
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 […]
Instreamer App Streams Zidoo X8/X9S/X10 HDMI Video Input to YouTube Live / RTMP Servers with FFmpeg
Zidoo X8, X9S and the upcoming X10, are TV boxes powered by Realtek RTD1295 processor with an HDMI input. The stock firmware already supports UDP broadcasting, but robbi5 decided he needed more, and designed Instreamer “HDMI IN Streamer” app leveraging work from Danman’s ZidoStream app for Mstar TV boxes and Zidoo’s own VideoAndHdmiIN app. Instreamer app supports the following: Streaming as MPEG-TS to network (unicast/multicast) Streaming in FLV format to RTMP server (e.g. Youtube) No need for intermediate recording file – thus no length limit Streaming runs in background HDMI out is usable as pass-through That looks good. Installation is easy. Download and install the latest Instreamer APK release Download and extract FFmpeg Android binaries to /mnt/sdcard You’ll be able to adjust a few video and audio settings after launching the app (not tested as I don’t have X9S anymore). You can now start a terminal, and stream HDMI input […]
