With his beautifully-colored classroom “noise-o-meter,” Mr. Jones knows when things are getting out of hand. When you were in school (or if you are in school) the teacher likely told the class to be quiet, perhaps repeating him or herself over an over during the day. The teacher, however, likely never really defined what is […]
An Arduino plus fake food and audio capabilities equals something truly unique! Randy “randofo” Sarafan had an idea when he was in college: a takeout container that talked. To the world’s great benefit, now that he knows about electronics, he finally made this dream a reality. Using an Arduino Mega with a Seed Studio Music Shield, […]
The MR-808 robotic drum machine looks like a gigantic Roland synthesizer, but plays with real instruments! The Roland TR-808 was released in 1981 and was meant to replace a human drummer for practice purposes, but was instead used to produce music itself, helping to birth the electronic, techno, and hip hop genres. Moritz Simon Geist […]
A few months ago, Connor Nishijima demonstrated a neat project highlighting the Arduino Uno’s “built-in motion sensor.” Now, he’s using the Arduino Mega’s “built-in anti-GPS” to guess which countries you’re NOT in. How, you ask? By reading the frequency of the alternating current (AC) cycles in his house using an open analog pin. You’ll need an Arduino Mega […]
Maker Shuang Peng has created a 13 DOF animatronic hand using an Arduino Mega, seven servo motors, and six air cylinders, along with a Leap Motion sensor for control. As briefly described on his Instructables page: There are various ways to control the hand. I’ve tried the Leap Motion sensor and the data glove, which catches my motion via Processing. Then the Processing communicate […]
If you’ve ever seen a TV commercial for any fast-food chain, then chances are you’re familiar with the burger drop shot–you know, that scene where ingredients like ketchup, lettuce, tomatoes, onions, bacon, beef patties and sesame seed buns fall from above and then stack themselves upon landing. Well, photographer/Maker Steve Giralt wanted to try capturing a shot like this on his own without […]
While it may not be the first (nor will it be the last) robotic bartender we’ve seen, Pierre Charlier has come up with a clever and affordable way to mix the perfect drink at home. Say hello to HardWino. The automatic cocktail maker consists of a six-slot, rotating beverage holder that is controlled by an Arduino Mega and uses a TFT […]
Growing up, there was nothing cooler than hopping in a go-kart for a quick spin around the neighborhood. But you know what would make it even cooler? If you built your own set of electric wheels. That’s exactly what two engineering students, Adrian Georgescu and Masoud Johnson, have done using commonly available components along with a secondhand frame they picked up […]
GitHub user Sanni has created a Nintendo cartridge and save game reader shield for the Arduino Mega. The ROM gets saved to an SD card. You can also read/write save files to the SRAM, display information about the cartridge on a 0.96″ 128X64 OLED LCD, and calculate the checksum of your ROM dump. You control it using the push button–one […]
As part of a thesis project, Belgian student Bruce Helsen built a dual-axis tracker for optimizing solar panel use. Although adding a tracking system to a larger installation can be pricey (and likely not the most cost-effective option), it can certainly come in handy for smaller units. Helsen’s dual-axis tracker fits two 12V 150W solar panels for a 300W peak output, and […]
