We cleaned, vacuumed, wiped and removed the old nest. Our nesting box is ready for the new season and we are waiting for a new breeding pair to move in like last year. Also this year you have the possibility to follow the brood in this nesting box via live video stream. The motion detection is already armed and sends the pictures to our Twitter account @RaspberryBlogDE.
I have to thank all visitors showing an enormous interest to our booth at the MakerFaire Berlin 2017. Special thanks go to James Mitchell from the Raspberry Jam Berlin who organized all items on display at the booth and arranged an amazing “Pi-Wars” show, popping hundreds of balloons!
And last but not least I want to thank our neighbors from Pimoroni. I enjoyed to meet your fabulous team – see you next year!
Issue 57 of the official MagPi magazine contains a Do-It-Yourself Artificial Intelligence kit made by Google. The build instructions inside issue 57 are straightforward, so that you can talk to an intelligent device within minutes.
However, the installation walk-through in the MagPi57 did not work without problems, therefore I recommend to follow the instructions on Google’s AIY Project Page.
The kit turned out to be very popular and it is currently difficult to get hold on it. It is sold out at many places :-(.
Starting with version 0.30, motionEye can be configured to overlay buttons on top of a camera frame. These buttons will then execute custom commands when clicked. Thus, it is possible control to control a pan-tilt bracket or to toggle IR light for a PiNoir camera.
Here I mounted a PiCam onto a cheap (0.40 €) pan-tilt bracket with two SG90 servos from Aliexpress.
It is a major problem in almost all large German cities, that fine particulate matter is frequently exceeding its maximum permissible value of 50 μg/m3. In a special issue of the Make Magazine (IoT special 01/2017), I read an article about the Nova PM SDS011 sensor, which is using the principle of laser scattering to measure the concentration of particulate matter between 0.3 to 10 μm in the air. The sensor is cheap (about 20 Euro) and easy to use, since it communicates via serial connection.
For placing the sensor into an enclosure, it is equipped with a nozzle that allows to connect a hose of max. 1 m length. The UART communication protocol requires a bit rate of 9600 baud, with 8 data bit, no parity and one stop bit.
