This Pizza Compass Directs You to the Nearest Slice No Matter Where You Are

With the advent of GPS and the handy Google Maps, traditional compasses seem pretty outdated. They’re not as intuitive, and they only point north. But what if there was a smart compass that pointed you towards what you really want, like, say, pizza? Engineer Joe Grand recently built a compass that directs you to the nearest slice of pizza no matter where you are. And in the wise words of pizza connoisseurs, the Teenage Mutant Ninja Turtles, it’s totally tubular.

David Hansel’s ArduinoFDC Converts an Arduino Into a USB Floppy Drive Controller

Requiring no additional hardware beyond an Arduino Uno, Nano, Pro Micro, Mega, or compatible, ArduinoFDC is surprisingly powerful.

Developer David Hansel has published a tool that aims to make it easy to integrate classic floppy drives with a modern computer: ArduinoFDC, turning an Arduino Uno, Nano, Pro Mini, or Mega into a functional USB floppy controller.

“ArduinoFDC consists of three parts,” Hansel explains of his Arduino Sketch. “A library providing low-level functions to allow reading and writing disks at the sector level as well as low-level formatting disks. Integration of ChaN’s brilliant FatFS library to provide file-level functions for reading and writing files and directories in a FAT (MS-DOS) file system and a high-level format function to initialize a FAT file system.”

You take care of a pet eyeball in this bizarre video game

“Avant-garde” is a French term that translates literally to “advance guard,” as in the vanguard that leads an army into battle. In the arts, the term describes people or works that are experimental and push the boundaries of their medium. Emily Velasco, of the Emily’s Electric Oddities YouTube channel, used an Arduino Nano to build a bizarre video game and “avant-garde” is the best way to describe it.

Carbon Nanotube Spaghetti Proves Perfect for Flexible, Wearable Energy-Harvesting Generators

Directly printed using water as the solvent, these eco-friendly thermoelectric generators are flexible and suitable for wearable use.

A team of researchers from Stanford University has published a paper detailing non-toxic, flexible energy-harvesting devices which they say could power future wearable electronics — thanks to carbon nanotube spaghetti.

“Carbon nanotubes are one-dimensional materials, known for good thermoelectric properties, which mean developing a voltage across them in a temperature gradient,” explains Professor Eric Pop of the material focused upon in the paper. “The challenge is that carbon nanotubes also have high thermal conductivity, meaning it’s difficult to maintain a thermal gradient across them, and they have been hard to assemble them into thermoelectric generators at low cost.”

DIY SDR DSP Radio with Raspberry Pi and RTLSDR Dongle

The radio presented above is capable of receiving the entire spectrum, from 500 kHz to 2 Gigahertz.

Software-defined radio (SDR) is a radio communication system where components that have been traditionally implemented in hardware (e.g. mixers, filters, amplifiers, modulators/demodulators, detectors, etc.) are instead implemented by means of software on a personal computer or embedded system.

The CelloBot (Robot Design Controlled by an Arduino Uno)

Hello, I’m Andre and this is how you can build and design your own robot with dancing features. This robot was designed as a team project for my junior design class at Georgia Tech. The entire system is completely controlled by an Arduino Uno microcontroller, with various user interface devices. The fundamental components to the motion of the system are two servos that have been attached to a model of a cello. This guide assumes you have experience with soldering, laser cutting equipment, c++ programming, circuit design, and 3D printing.

Streamer-Focused Arduino-Powered Sparkpad Packs Keys, Volume Control, OLED Display, and More

Supplied as a kit with open source firmware, the Sparkpad aims to be a one-stop device for streaming, video editing, and more.

Maker Patrick “Paddy” Thomas has launched a display-equipped RGB macro pad, or “reconfigurable control surface,” built around an Arduino Pro Micro and with streamers in mind: the Sparkpad.

“The Sparkpad is a reconfigurable control surface, primarily aimed at Streamers. The V1 Sparkpad is designed to communicate with streaming software — such as OBS – via HID commands sent over USB,” Thomas explains of the design. “However, due to its modular hardware design and open source Arduino firmware, there is scope to do much more. We are hoping to foster a development community, and we will continue to develop improvements for the Sparkpad as and when we can.”
