Adafruit has written a comprehensive tutorial on getting the Node-Red visual development environment to work on the Raspberry Pi and given details on what you can use it for.
Safety Attention Monitor uses a #RaspberryPi for car safety
James Hobson and his team at Chico State University have created a device to monitor drivers and their facial movements to determine if they are looking at the road. They’ve used a Pi and camera module plus OpenCV to do facial tracking. Read more about the project here.
Help fund a wearable technology workshop for Girl Guides
This isn’t strictly Pi-related, but it is to do with electronics and education so I thought I’d blog about it anyway!
Pi enthusiast (and Babbage the Bear-hugger) and STEM Ambassador Charlotte Godley wants to run an educational workshop for her local Girl Guides group. The subject of the workshop is wearable technology. For this, she needs to get hold of a load of GEMMA Arduino boards and other stuff (pictured above). Although she’s got some funding from the guides, she needs your help to fund the rest of the workshop. She has secured discounts for the supplies and is eager to get going on it. Her enthusiasm has come over in numerous Tweets and she’s created a video in which she talks about her plans:
This is a great workshop idea and I think it’s fantastic that she’s going to the effort of trying to crowd-fund it.
So, if you can spare a few quid to help support her, that would be fantastic! As of now, she has raised £109 of her modest £430 target. So, please help if you can! I know she’ll do a fantastic job on the workshop.

Starting a Code Club – what happens?
Author Sean McManus has set himself the task this year of starting up a Code Club in a local junior school. You can read about his experience with the initial steps here. You can find out more about the Code Club movement on their website.
Network monitoring with MRTG on the #RaspberryPi
Muhammad Furqan has written a tutorial about using the Multi Router Traffic Grapher (MRTG) software on the Pi. The software uses Simple Network Management Protocol (SNMP) to monitor network devices and draw graphs showing how much traffic has passed through interfaces over time.
Playing sounds on the #RaspberryPi
David Whale’s Raspberry Pi club is doing great things. This time, he and his young members played around with sound on the Pi. This involved working out a solution to an audio problem caused by an HDMI-to-VGA adaptor – very well worth reading if you use such an adapter and great fun to read anyway. They’ve also been looking at how to play sounds using PyGame in Python.
