Best place to waste your time …
I just received a package of 10 flexible keypads I bought on eBay for 15.88$, shipping included. Having a keypad in your project opens so many possibilities, at 1.59$ each I think it’s a deal! I found a keypad library for Arduino on the Arduino Playground. I made some minor modifications to the sample...
You can now find the code of the twitter robot on my github at: https://github.com/pchretien/tweetbot Feel free to fork … copying is not stealing! :)...
I just received my Beaglebone and started experimenting with it. The Beaglebone is a low cost, single board Linux computer with tons of IOs to interface with the physical world. My objective is to make a Python Robot using the Beaglebone as the brain and my Makerbot to build the frame. I found an...
I presented this project at the 28th Montréal Python meeting. I posted the slides of the presentation in my previous post here. The objective of this project was to demonstrate the use of pyserial and XBee to wirelessly control a robot. This project was also my first attempt at using the Tweepy library. The...
Today at 18:30h, I’ll make a short presentation at the 28th edition of the Montreal Python. I’ll present my PyGame Wireless Game Controller and a robot controller by the web. More details about the presentation on the Montreal Python Website: http://montrealpython.org/2012/03/montreal-python-28-lithographic-lobotomy/ You can get the slides of the presentation here: https://docs.google.com/presentation/d/1KTqljkl-fSZyuhXonCrQN10HsEFdp5AsavMEvj8bdRU/edit#slide=id.p...
I received a comment from “N00B” on my Build an Arduino Clone post pointing out a mistake I made by connecting 5V power to the pin #6 instead of pin #7 of the Atmega328 micro-controller. He was right and I changed the text of the article from pin #6 to pin #7 but, what...
Following the Open Hardware Summit I went to the Maker Faire World in New York city. This event was held in the same location as the OHS, at the New York Hall of Science. 3D printers were all over the place! Of course there was the 3D printing village where Makerbot, Makergear, Ultimaker, Botmill...
When you make a project using an Arduino board, you often need a case to attach the Arduino onto your project. This small project is my first attempt to make such a case that can be adapted to all my projects. To make it parametric I am using the OpenScad application. OpenScad is an...
Controlling DC motors is at the heart of many robotic projects. Servo motors are sexy but DC motors are cheap and a lot more useful to control wheel based robots. In this article I’ll display a “robot shield” circuit that allows you to use cheap motors to drive your robot. Wiring This shield has been built...
For this project, I keep the same controller as in the previous post but, instead of controlling a servo motor through a second Arduino, I will use it as a game controller. The game will be played on my desktop computer. Since I am not very good at writing games, I downloaded the PyGame...
