Use your Raspberry Pi’s GPIO pins at the same time as the SenseHAT
Keith Ellis does a rather good line in tutorial videos over at pi-tutorials.co.uk. Recently, he wondered if it was possible to use the Raspberry Pi’s GPIO pins with the SenseHAT attached. At first glance, it seems that it’s not possible due…
International background radiation research project uses Raspberry Pi
A group of UC Berkeley students working with researchers at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have developed devices that will measure and report levels of background radiation. Called DoseNet, the open-source project aims to get…
Read analog sensors on the Raspberry Pi with the Analog Zero – Kickstarter!
A couple of weeks ago, I received from Alex Eames a new board he’d been working on called the Analog Zero. I blogged about it then and have continued to think about it and I really believe it’s the best solution currently out…
Use an analog to digital converter to get analog sensor readings on the Raspberry Pi
Gus over at PiMyLifeUp has done a great tutorial on using the “famous” MCP3008 analog-to-digital converter chip to read values from a light-dependent resistor. He goes through wiring it up and programming it using the spidev Python library. I prefer the…
Cambridge start-up uses Raspberry Pi for low-cost water quality scanner
Waterscope, a Cambridge start-up company, has developed a low-cost, 3D-printed water quality scanner based around a Raspberry Pi and a microscope. Alex Patto, Richard Bowman, Nalin Patel and Tianheng Xhao met on iTeams, a programme started at Cambridge University which aims to help…
Body movements create music with the help of a Raspberry Pi and Arduino sensors
Calvin Cherry, an electrical engineer graduate of University of Wisconsin – Madison, has created a new musical instrument called Music from Motion which adds layers of instrumental samples as he moves different parts of his body. Stop sniggering at the back!…
Raspberry Pi UPS HAT from S.USV – review
I was sent one of these HATs to get some feedback and a review. I’m free to say what I like. Introduction Today, I’m reviewing the S.USV HAT from German company S.Seprotronic GmbH. The HAT comes in two flavours – Basic…
Terrifying Terror from a Raspberry Pi Creative Technologist
Last year, Yasmin Curren was selected as one of the Raspberry Pi Creative Technologists. On 23rd April, I attended the CTs exhibition at Raspberry Pi Towers and saw her project. It was an interactive video-based experience about monsters living under…
Raspberry Pi-powered, GPS-enabled metal detector robot
Ingmar Stapel from Munich has created a robot that will carry out metal-detecting activities. The robot is fitted with a GPS to track location and a pan-and-tilt camera to enable the person who is controlling it to see where they…
