Arduino Robot 2 - Wandering Tank
What a busy couple of weeks I have had. Many upgrades for the printer have arrived, and work continues on understanding and possibly building Hexy before my Kickstarter version arrives from Arcbotics. In this post I will cover the upgrades I have made to the printer; why I made the upgrades, their cost; and finally show some updated Hexy prints to show off the new accuracy. First; I was printing the Seej Starter Set, in preparation for taking my printer to work on my last day. So, because of this complete printer failure and needing to order new parts anyway; I decided to do the upgrades that are suggested to get good accuracy. 2 x Timing Pulley, GT2, 20 Tooth - $11.00 each3 x Timing Belt, GT2 - $9.00 each2 x Motor Shaft Coupling, 5x8mm - $7.00 each. Moving along... So first, the change to the coupler: With the upgrades installed, it's like a new printer! So with an upgraded printer, it was timing to do a comparison print and produce a part for Hexy.
Interfacing a sensor with an Arduino
The world of hobby electronics is one that has seen explosive growth and massive changes over the past few years. The biggest changes have come from the level of computing hardware that is available to the hobbyist. From very simple microcontrollers to full PCs on a USB stick, all sorts of options are available. One of the more popular options is the Arduino, which falls between these two extremes. The entire Arduino project has been a proof of the power of open source. All of the hardware designs are open source, meaning anyone can take them and manufacture Arduinos. In this tutorial, you will get a development environment set up to work with your Arduino. Resources ArduinoArduino Playground Step by Step Step 01 Get your hardware The first step is to select your hardware. Step 02 Plugging in Most Arduino boards interface over USB with the development computer. Step 03 Software Installing the required software has gotten much easier recently. Step 04 Start a new program Step 05 Verify your board

Video Tutorials
From Processing by Jose Sanchez In an intent to give back to the open source community of processing and also help students to re-visit some subjects that may be unclear, I have developed some video tutorials, please send some feedback to keep improving them. List of videos by Fun Programming This series of tutorials start at the absolute beginning: what's a pixel. This project started on August 1st, 2011 and new videos are being produced each week. Watch at Fun programming I recommend watching related Khan Academy videos as well if you want to go deeper into geometry and math. by Daniel Shiffman These tutorials are for advanced users and follow the content from The Nature of Code book.

Practical Arduino: News
Tutorials: PHP
The purpose of this tutorial is two-fold. Number one, we’re going to demonstrate how all of the basic fundamental concepts you’ve learned with Processing (variables, conditionals, loops, functions, objects, arrays) extend to programming in other languages. Second, we’ll see how there are certain types of tasks that you can farm out to a server-side script (in this case, written in PHP) that cannot be done easily inside of your Processing code itself. Thanks to Shawn Van Every and Dan O’Sullivan, this tutorial is based off of material from Shawn’s quick and dirty PHP as well as Dano’s PHP sample code. What is PHP? PHP (which originally stood for “Personal Homepage”, but now stands for “Hypertext Preprocessor”) is a scripting language designed for creating dynamic web pages. <html><head><title>Your Page's Title</title></head><body> The <strong>content</strong> of your <em>web page</em>.
