Reverse Engineering Hardware of Embedded Devices Nowadays, we are living in a world dominated by embedded systems. Everyone can be spied on through various channels. Routers, IP-cameras, phones, and other embedded devices are affected by security vulnerabilities and are therefore easily hack-able.  This article covers some basic hardware reverse engineering techniques on PCB-level, which are applicable to any electronic embedded

Intel Takes a Step Back In The Internet-of-things A few weeks ago,  Intel has quietly discontinued its three SBC boards, the Joule, Edison and Galileo. These pretty much represented the presence of x86 chips in the IoT market. SBCs are perfect for the IoT space. So, why would Intel kill off its SBC boards? It could be read as an admittance that its IoT strategy has not

No coding required: Node-RED on a Raspberry Pi | Node-RED is an easy-to-use programming tool that can be used for handling IoT signals. This article shows that Node-RED can also be used to quickly integrate and test hardware devices. As you can see from this tutorial, connecting and testing a cellular mode with Raspberry Pi using Node-RED required no coding at all. For more information about

Voice Controlled Bluetooth Car: 5 Steps This looks really interesting! Everyone has used the remote controlled car…. but what about a voice controlled car??? Ever used it?If not then you will build it now. Just you need an arduino as the brains and a smartphone.  Arduino nano is the brains of the project. Now the voice feature actually works with

Lessons for getting started with DIY IoT home automation | We live in an exciting time. Everyday more things become Internet-connected things. They have sensors and can communicate with other things, and help us perform tasks. Home automation is made possible by amaetuer developers and tinkers because the price of microcontrollers with the ability to talk over a network continue to drop.  Along the way, the writer has learned

Visualizing Smog Sensor Data with the help of Vert.x, Prometheus, and Grafana – RHD Blog The article shows an end-to-end example of an IoT device sending data in a certain format. A gateway is implemented with the help of the Vert.x framework, which does all the magic of connection handling etc.Finally, the data is stored in a Prometheus time series database and graphed via Grafana.

How to pre-test your product’s antenna | EDN Your wireless product’s end-to-end success dictates that your customers will rely on your antennas to perform well in their system. Most hardware and software is thoughtfully tested before sale or deployment, but why are so many antennas ignored? There is no reason to defer or ignore your antenna evaluation; help is available.
