Purpose This project was built for the Things that Think undergraduate/graduate class CSCI 4830-7 and CSCI 7000-7 for the University of Colorado at Boulder.  Our group consisted of one graduate and two undergraduate students.  We worked on the project for 8 weeks, most of the time trying to learn how to program the arduino and learning the basics of circuits.  If you are looking to build this project, we do ...

Last year I was fascinated by the "How to build your own Quadrocopter" by Lenz Grimmer and decided that somehow I should try to do a similar thing. This talk is about the way I'm building a bi-copter using lessons learned for last year's talk and also with the errors I've made so far. My journey to getting a flying device running Multiwii is not yet complete. In this talk I will present all the common probl ...

So after 5 previous versions that had various flaws, I now have an Arduino robot that actually works and although basic is very cheap – although there a probably a few more flaws so please point them out to me but this is a good start on how to make your own robot. In order to catch up, please see my previous posts below, describing the problems that the other 5 versions had, how the h-bridge chip works and ...

The PhytoBot is a semi-intelligent plant which responds to external stimulus (light intensity and light location) and responds to it as a phototropic plant would. Essentially it is designed as a piece of interactive artwork for operation over a long period of time. The motivation driving this was triggered by the lack of understanding & acceptance of plants as reactive living organisms. Many of us are s ...

Hello Friends! Well, as you know, in September the new premiere shield  of Arduino, Arduino YUN. This little friend has a Linux embedded system with which we can run anything you can think of (at least so far). While there is very little information on this new board, with departure in the guide that provides the Arduino page (which will link later), plus a little knowledge of many Linux, can carry out a ma ...

Bobble-heads!!! Every sports fan loves em, but they're kind of boring, just sitting frozen on your shelf :-( I thought it might be fun to create an Automatic Bobble-head Bobbler something that can wake that old bobble-head up and get him nodding away. I finally found time to get one working just in time to be a Christmas present (and of course be the subject of a new Instructable). Concept phase: I first th ...

Obstacle avoiding vehicle, continue in “3D Laser Range Finder” series ( project 1, project 2). The basic idea is the same, measuring distance using red laser pointers, CCD analog camera and Arduino UNO.  Modification was made in geometry.  Two lasers were set for “far field” obstacle detection, few meters in front of vehicle on left or right side. Primary mission is to trigger left / right turn before a car ...

The world's first completely open-source Bitcoin ATM for Education and Experimentation. http://openbitcoinatm.org for more information. Step 1: Fabricate Box and Faceplate Out of a piece of 12″x12″ aluminum sheet metal, cut two rectangles and drill six rivet holes and four holes to attach the bill acceptor. Cut aluminum angle into two 11 1/2″ lengths. For each aluminum angle, drill and tap two holes; drill ...

I have been spending the last few months doing research into biologically inspired robotic structures. While my approach may seem formalistic in nature, these devices were simply a means for ultimately conducting social research. This desire stems from my experience building Simple Bots, and their subsequent display at multiple Maker Faires. While displaying these robots, I observed that the thousands of pe ...

Let's make a simple inverted balancing robot, and operate it. You need only half a day to do them, if you have an arduino and some materials. [a video of a robot you would make] introduction: After a few work with arduino, I have thought of making an inverted pendulum. Then I had two policies for the project. simple as possible bootstrap (without referring to website) Though they has been kept (*1), it has ...

Project Gado is an initiative which aims to create an open-source archival scanning robot which small archives can purchase for $500 and use to autonomously scan their photographic collections. This talk presents the Gado 2, a prototype ...
