Instructables user Tall-drinks wanted to learn how to use the BLE Mini Bluetooth 4.0 Interface from Red Bear Labs so he modded a lamp to display the current weather outlook from OpenWeatherMapAPI. By stuffing an Arduino, the Bluetooth module, a servo, and a cardboard gobo inside the lamp shade, he was able to have his […]
With parts that could have been used to build a remote control jet, ScratchBuiltAircraft on Instructables managed to make something even cooler: a remote-controlled hovercraft.
The body of the hovercraft is made of foam board, while the plastic ‘skirt’ around the bottom is just a simple heavy-duty garbage bag. Where the build gets really interesting is in the electronics. The thrust for the hovercraft is provided by an electric ducted fan powered by a LiPo battery. This fan also pushes air into the skirt of the hovercraft thanks to a duct located directly behind the fan.
The Fixers Collective will be returning to Maker Faire New York this month. They invite attendees to bring their broken stuff and learn how to fix it. They describe themselves as an “ongoing social experiment encouraging improvisational fixing and mending and fighting planned obsolescence.”
There are a lot of different shields out there for Arduino. However, sometimes there arises a need to make your own. Even more plentiful in the world of electronics are integrated circuits that do a lot of nifty things. Some control output, some input, and some are sensors. In this edition of Projects with Ryan Slaugh I show you how to make your own custom proto shield.
RFID (radio-frequency identification) systems are all around us. They help us get through toll booths faster. They help stores keep track of inventory. They are even in a lot of toys.
But there is no reason why the RFID chips need to stay in their original housing. In this project, I am going to show you how to transplant a RFID chip into a different housing to make it more convenient or at least more fun use. You can make an RFID reactive wallet, multi-tool, or cell phone case. The only limit is your imagination.
College hacking marathons, or hackathons as they’re known to most college students, are something every college student should experience at least once. Hackathons are really awesome ways for you to just get into the zone and just “hack” for about two days straight, more or less. While it wasn’t immediately clear to me what it took to throw together a hackathon, an event and a summer of preparation later, I think I’m getting a better idea.
For those of you who are contemplating or in the process of hosting your own Hackathon at your campus, here are just a couple of concepts I think you should keep in mind.
Taj Singh has built an electronics Scrabble tile dispenser based on a PIC 16F628 microcontroller and a stepper motor.
