Rui Santos from Portugal has written an excellent, comprehensive tutorial for those who want to get into ESP8266 boards and control them from a Raspberry Pi. He uses Python on the Raspberry Pi, with imported MQTT libraries, and C code…
Alex Eames took a (cheap as chips) Wemos D1 mini (which has an onboard ESP8266 wifi chip), connected it up to an analog temperature sensor and then flashed a script to the board that would send the sensor readings to…
Spencer Organ has been putting his making skills to use with this Harry Potter-inspired build. Taking his cue from both the Weasley Clock and the Marauders’ Map, he’s taken a Raspberry Pi, an Explorer HAT, an Arduino, some servos and…
A team from Villanova University, Philadelphia, comprised of four faculty and more than twenty-five students, has developed a ‘bomb squad’ robot. The robot is intended to be used in developing countries to deal with explosive devices and uses a Raspberry Pi…
Over at DesignSpark, Dr Lucy Rogers has written a great tutorial which fuses the Raspberry Pi, 3D printing, an ESP8266 module and some Neopixels into a bus warning system. The system has the following features: A visual alert to tell…
A Mexican team of Paloma López, Leslie García, and Emmanuel Anguiano (together, they are known as Interspecifics) have created a nature-driven musical instrument. Micro-ritmos is an art installation in which ‘music’ is generated by patterns formed by bacterial cells. The material…
James Poole has taken a string of Neopixels (UK/USA) and hooked it up to an Arduino. He’s then taken a Raspberry Pi and used it to control the Arduino via a web interface. James then mounted the whole lot on…
Wendell Kapustiak has built a self-playing wooden pipe organ. The organ has 42 wooden pipes (representing 3.5 chromatic octaves). Each wooden pipe is different and had to be custom-cut to play the right note. A “blower” used to cool data centres…
Plum Geek have previously launched, and successfully funded a series of Arduino-powered robots on Kickstarter. Now, they’ve moved into the Raspberry Pi arena with the Spirit Rover. Inspired by the NASA/JPL Mars Rover, the full kit features a custom circuit…
Martin Hertig took a guitar bag, hooked up an Arduino to the zips via conductive thread to make a MIDI controller and then added a Raspberry Pi into the mix to create his project, called Zippy. The Pi runs FluidSynth synthesizer…
