Reading Time: 4 minutesRejoice! It’s time for a new issue of Hackspace magazine, packed with things for you to make, build, hack, and create! HackSpace magazine issue 9 Tools: they’re what separates humans from the apes! Whereas apes use whatever they find around them to get honey, pick pawpaws, and avoid prickly pears, we humans take the step […]
Reading Time: 2 minutesIn our latest resource, we show you how to create a website and use it to document your coding projects. Why document your code? Search the web with the right key words for your programming conundrum, and you’re bound to find someone who has written software to address a question that’s at least similar to […]
Reading Time: 4 minutesThe sun is actually shining here in Cambridge, and with it, summer-themed Raspberry Pi projects are sprouting like mushrooms across our UK-based community (even though mushrooms don’t like hot weather…). So we thought we’d gather some of our favourite Pi-powered projects perfect for the sun-drenched outdoors. Air quality monitors and solar radiation With the sun […]
Reading Time: < 1 minute“Magical” fountain bends time under Arduino control Arduino Team — July 16th, 2018 Years ago, engineer and photographer Harold “Doc” Edgerton figured out how to “bend time” by pulsing a strobe light at the nearly the same speed as droplets of water, making them appear to move in slow motion, freeze, or even more backwards. […]
Reading Time: < 1 minuteAn Arduino “Whack-a-Button” Reaction Game Arduino Team — July 16th, 2018 After Instructables user R0RSHACH’s son won a place at the World Scout Jamboree in 2019, the maker decided to create a fairground-style game for fundraising. The resulting device is akin to a Whack-a-Mole or Batak game that can be found at high-end gyms, and features eight […]
Reading Time: 2 minutesimPulse is an energy harvesting alternative for bicycles Arduino Team — July 16th, 2018 Javier Betancor is developing a system that collects power as you ride a bike, with the goal of powering data collection and lighting. “imPulse” uses a stepper motor for power generation, along with a geared hub to make the motor spin at […]
Reading Time: < 1 minuteStepper motor utilized as a rotary encoder with Arduino Arduino Team — July 16th, 2018 Stepper motors work by alternating a series of magnets in order to rotate its shaft by a certain angle. When the shaft is manually twisted, these magnets produce an electrical signal in a predictable pattern, which as shown in the […]
