A new prototype of a lithium-sulphur battery – which could have five times the energy density of a typical lithium-ion battery – overcomes one of the key hurdles preventing their commercial development by mimicking the structure of the cells which allow us to absorb nutrients. This gets us a long way through the bottleneck which […]

[Sean Hodgins] has a knack for coming up with simple solutions that can make a big difference, but this is one of those “Why didn’t I think of that?” things: addressable seven-segment LED displays. [Sean]’s design is basically a merging of everyone’s favorite Neopixel RGB LED driver with the ubiquitous seven-segment display. The WS2811 addressable RGB
ADDRESSABLE 7-SEGMENT DISPLAYS MAY MAKE MULTIPLEXING A THING OF THE PAST Continue Reading
Last Thursday I had a lot of fun doing a workshop at my college (UMass Amherst) where I taught students to use a WiFi-enabled Color LED matrix combined with Javascript programs to create animations displayed onto the LED matrix. The matrix is made of 5×7 WS2812 (NeoPixel) LEDs. I’ve actually designed it two years ago

Sun tracker systems are widely used in solar panel setups to get maximum performance. You may want to use one in your personal solar panel setup. Now you can make your own with an Arduino, following the project that’s designed by RobotGeek Team and Wade Filewich. Parts You’ll Need: RobotGeek Desktop Roboturret x1 RobotGeek Rotation Knob x2
Hardware designer and serial Kickstarter entrepreneur Patrick Thomas Mitchell has taken to Kickstarter for the 30th time to launch his new Arduino E-Z COMMS Shield which is equipped with air and integrated LCD two indicator LEDs, and 256 audio words, enabling you to easily add speech to your next Arduino project. Watch the demonstration video below

Makers and skateboarders who fancy building their very own electric longboard may be interested in a new tutorial created by the Electronoobs website providing details on how to build your very own DIY Electrical on board. Equipped with a battery pack, radio receiver N5060 brushless motor and a little Arduino hardware and programming the electric skateboard is
Geiger counters are devices used to detect radioactive emissions, most commonly beta particles and gamma rays. The counter consists of a tube filled with an inert gas that becomes conductive of electricity when it is impacted by a high-energy particle. The Geiger–Müller tube or G–M tube is the sensing element of the Geiger counter instrument
The Makerspace has its own equipment (and a meetup page), which is installed in a multi-purpose room during the events. Library staff also do out-reach events (to schools for example) and in-house courses and workshops (Arduino for example), and the Makerspace has a loose alliance with the Surrey and Hampshire Makerspace, which also meets in Gulidford.
Despite how good microscope you have, stand is still very important part of final assembly. And while there are many commercial ones made of cast iron, they might cost more than a microscope head itself. I decided to make stand from wildly available material laying around – it’s MDF (Medium Density Fiberboard). Advantages – stable
Arduino enthusiasts, hobbyists and makers looking to control their projects from afar. May be interested in a new customisable wireless remote control designed by Schindler Technologies for the Arduino platform. Launched via Kickstarter this week the project allows you to easily control your projects such as a drone, remote control car, speakers or anything else your
