With all these Raspberry Pi and Arduino projects in mind I am developing this gauge view for IoT apps on Android. There are some alternatives around, but I’m not quite satisfied with them as the...Read More
Introduction As a low power device the Raspberry Pi makes for a perfect network monitoring host. I’m running Nagios 4 on a Raspberry Pi 2 with a 5V/2A power supply. Fixed IP A fixed IP address i...Read More
Introduction We have seen how to control the Pi Rover over HTTP. However, you may find it a bit of an overkill to install a webserver bundled with PHP just to control the motors. A leaner alternative ...Read More
Which gerbil hardly sounded wonderful? Meet the Dada Bot. It uses a context-free recursive grammar to produce its wisdom. The engine is rmutt, a piece of software that I excavated from the deep entrai...Read More
Introduction Now that we have a programmable robotic platform, built with a Raspberry Pi, a motor controller and a chassis, we’d like to control it remotely, from a PC and later maybe from a mob...Read More
Introduction The need for a new access point arose out of discontent with the Speedport W723V DSL router as provided by T-Online. De device tended to become less stable as more wireless devices got co...Read More
Introduction To easily access our wireless Raspberry Pi projects (like the Pi Rover) over SSH, FTP, HTTP or whatever, we want to assign a static IP to the WLAN interface. In this example the network a...Read More
Introduction The HC-SR04 can be used to measure distance and detect obstacles in robotic projects. However, the reported range is not always accurate, small objects are mostly not detected at all and ...Read More
Introduction We’ll build a mobile robotic platform with a Raspberry Pi on a chassis. A Pololu DMC02 motor controller board is used to drive the engines. The controller receives serial commands f...Read More
What I needed was a live video stream to provide some sort of an FPV experience. Streaming over VLC or ffmpeg turned out to be suffering from too much of a time lag. Streaming over MJPEG Streamer with...Read More
I needed a camera to be turned off at night and a PIR sensor (controlling a light switch) to be turned on. A photoresistor would be an obvious choice here, but we can also accurately calculate twiligh...Read More
