The MQ-3 is an alcohol gas sensor that is available for about $5 from Sparkfun, Seeed Studio, and others. It’s easy to use and has sparked the imagination of anyone who has dreamed of building their own breathalyzer device for measuring the amount of alcohol in the human body. I got an MQ-3 sensor a […]
This project started as many of mine usually do, as a honey-do. We have compiled an extensive list of our book and movie collections on our computer at home, but my wife wanted to be able to scan the list from the video store (yes, we still go to the video store). So I created […]
Quadrotors are the new Segway’s: a mesmerizing, somewhat magical, self-stabilizing platform that every tech person wants to have. You can’t ride a quadrotor (well, maybe you can), but they do fly, and you can build one yourself from scratch! I helped with a previous quadrotor build (Instructable here), and after flying it I decided I […]
Need more Arduino board? Do not spend more money for another one. Why not try to build your own DIY Arduino board? It is easy and simple. DIY Arduino Step 1 Get an Atmega328–PU or Atmega328P-PU (with bootloader inside). atmega328p A brief introduction on the Atmega328 chip: 8-bit MCU 32kB Flash Memory 1kB EEPROM 2kB […]
This electronic instrument allows you to sequence and loop audio and MIDI data. Most of the time I use it to sequence drum samples so I can play around with different beats and rhythms. The really great thing about this instrument is that it is very portable, it fits in your hands easily, runs off […]
I’m working on an Arduino clone. The Arduino is essentially an ATMEGA328P development board with a bootloader pre-loaded. There are a lot of custom macros built into the programming interface that make it really easy to use, and even easy to build some powerful applications. Arduinos have taken off and can be found everywhere, doing […]
The Freetronics LeoStick is a handy break-out board for the ATmega32U4 microcontroller. The board has a convenient USB stick format, and is based on the pinout and connections of the Arduino Leonardo reference design for compatibility with the Arduino IDE. Before you plug in your LeoStick for the first time please read this section of the […]
So, I have always wanted a nice lamp by the side of my bed, Something simple with out any buttons. Of course this would mean it had to be wireless. I also wanted to use it from my bed but not getting out of my bed to turn it off. So it had to be remote controlled, […]
BOXZ is is an open source robot platform for interactive entertainment! We connected Arduino, Plexiglass(or cardboard) Origami and your idea together, so we can easily and quickly build a remote robot by ourself! You can assembled it like LEGO! We can use it to playing football game, racing, fighting or some other interesting things! Follow […]
Tyree (he wears a tie and he has tires) actually smiles after he bumps into something (see video). Using an Arduino motor shield, he detects obstacles using the “more current into the motor means something is in the way” principle. Tyree started out as a sketch and morphed into a real object thanks to Autodesk’s […]
