Internet of Things gardening project with a Raspberry Pi Zero W and Analog Zero

Just a quick one… it is my birthday after all!!! 🙂

Les Pounder has blogged a gardening project over at Element 14. The project uses a Raspberry Pi Zero W for connectivity and a RasPiO Analog Zero to read an analog input: a soil moisture sensor. He has also connected up an I2C Flora UV sensor and even links up to Gmail to send you email alerts. Take a look here.

Ryanteck Ltd shutting up shop after several years in the Raspberry Pi community

I’ve just received sad news. After several years of operating in the commercial arena of the Raspberry Pi, Ryanteck Ltd is closing down. Ryan Walmsley, proprietor, just announced it via email. Ryan has been a leader of the Pi community, especially in the early days when he was a young programmer showing what the Pi could really do and developing one of the first motor controller boards that plugged directly into the GPIO pins. In recent times, he ran several Kickstarters culminating in the excellent RTk.GPIO board which gave you access to many more GPIO pins as well as bringing physical computing to PCs and Macs. Over the next few months, Ryan will be running a closing down sale so head over to his web store to pick up a bargain. He’s expecting to cease trading at the end of October.

Raspbian Stretch has changed the names of network interfaces on your Raspberry Pi

James was trying to allocate a static IP address to his Pi. He did what he’d always done and allocated the static address to eth0 but was then bewildered as to why it wasn’t working. He discovered that the naming convention for network interfaces has changed in the new version of Raspbian (Stretch) to an amalgam that includes the MAC address of the Ethernet port. He’s written up his findings on his blog.

Update: This only effects brand new installs of Raspbian. So, if you upgrade your Jessie to Stretch using apt, the interface names stay the same. The interface names change, however, if you install Raspbian Stretch from scratch.

I personally think this is “a bit crap”. I know it’s becoming the ‘standard way of doing things’ but for goodness sake… To change something like this is in the “almost pointless” category in my eyes. But what do I know?

Create a YouTube streaming box with a Raspberry Pi

Tinkernut has taken a Raspberry Pi, a camera module, added an 2.8″ Adafruit mini-touchscreen and a mini USB microphone and created a YouTube-streaming box. He’s programmed a touchscreen interface to allow him to preview the video and then added another button to send the stream to YouTube. He’s written the whole thing up as a tutorial and covers various tricky things such as getting that touchscreen working with a Jessie-based operating system and setting up FFmpeg. Take a look how he did it here.

Use a Raspberry Pi and the SenseHAT to create a mini-weather station

Ville Salminen has written a nice tutorial over on his blog in which he takes a Raspberry Pi, adds a SenseHAT and then programs it to access the SenseHAT sensors to create a mini-weather station. He uses Flask to create a simple web interface, so there’s plenty to learn here. Read the tutorial here.

New version of Raspbian released for the Raspberry Pi – hello, Stretch!

The folks over at Raspberry Pi have announced the immediate release of a new version of Raspbian, based on the Debian Stretch OS. There are various small software changes as well as the big update to the underlying operating system. You can read more on raspberrypi.org here and download the new image here. Please note: it is possible to upgrade from the previous version (Jessie) but the procedure is not recommended, so you may as well start with the new image!
