Introduction This will be part one in a series where I ( A software developer ) share my experiences in an attempt to build a fully wireless robot. This series will be targeted at other software developers wanting to do the same , who can hopefully learn from my mistakes , and electronics engineers who would like a good laugh. The software: As this is aimed at software people we will start by talking about the software, before delving into the unknown and getting electrocuted. Before I even started buying parts, I had decided to go with the following "stack": Raspberry Pi with wifi dongle Arduino microcontroller Firmata Johnny-five As you can tell from the need for johnny-five this is indeed a JavaScript robot. The Idea is to run the JS on the Pi and have it control the Arduino and in turn control the robot. One thing to note on this is that the Pi's default package manager does not load the latest version of node.js so you are going to have to compile a ne

I've started a project that I hope really gets off the ground. It's just a simple github page that lists successful nodebot projects. The idea is to keep a list of successful projects that detail the hardware and open source the software involved in making the nodebot.  This will give people an indication of the complexity and cost of a project before diving in and hopefully sidestep any issues the original creator may have encountered. I hope this will serve as a platform for beginners to launch off of ,nodebot veterans to pass on knowledge and as a gauge to the size of the nodebot community. As a start and to show what I had in mind , I've added my own project as an example to the list. However any input on formatting would be graciously accepted, after all, this is open source!

Most of the time when you are looking for a way to run Node.js as a production server on Windows you will just run into IISNode , now IISNode is a great thing ,but I'm a fan of choice and most importantly , not a fan of XML web config files. I wanted to run my node server on what ever port I wished,or maybe even a different server and just have IIS reroute the traffic from a particular URL to the node process(so a proxy), this allows you to still manage your own load balancing and possibly scale up from that point without having to bother with IIS again. So first things first you will want to download and install the URL Rewrite and ARR modules for IIS ARR (Application Request Routing) URL Rewrite Once thats done lets crack open IIS and open up Application Request Routing, then navigate to Server Proxy Settings and Check Enable Proxy and Apply. Now lets create an an application on our Default Website that will link our url to the node process, h

Reverse proxy Running node alongside Apache takes little effort, all it requires is a reverse proxy , which is way less of an effort to set up in Apache than it is in IIS  and a way to run your node process as a service.  To set up a reverse proxy in apache simply add the code in the following gist to the end of your httpd.conf ( located at /etc/apache2 on OSX ) just before the line:  Include /private/etc/apache2/other/*.conf . Loading Gist .... This will re-route any traffic from yourserver/node to yourserver:8080 . Of corse line 14 ( ProxyPass /node http://localhost:8080 ) can be edited according to your liking , but this is just an example. Thats it when it comes to the reverse proxy , all you have to do is restart apache and all requests to yourserver/node will now go to the node process running at yourserver:8080 . Forever Now that we have Apache rerouting the traffic to the right spot , we should set up the node server as a daemon so that it

Prerequisites You will need node.js and npm installed , and should have at least some knowledge when it comes to node, if you do not , I suggest you try some example code in node before diving into controlling hardware with it.  You must have the Arduino IDE installed on your machine You must know how to get an LED working on pin 13 of an Arduino Set up the Arduino Wire up an LED to the Arduino on pin 13 and plug it into your development machine. Now we need to get it ready to talk to johnny-five. To do this simply follow the instructions under johnny-five's readme Set up the project  Create a folder on your development machine for the project , in this folder create the server.js and index.html files. Copy the code from the files in this gist  to the respective files. Loading .... We aren't done yet , we need johnny-five and the narf for this to work. In your project directory run the following command: npm install narf johnny-five If that succeede

The word Innovation , it drives me insane! I think I havent heard it used correctly this entire year. Apple uses it incorrectly a lot by calling improvement innovation, and people ridicule them for that. Yet those same people say things like "Patents hold back innovation". Just wait a minute? what ? Patents (saying this is my new idea and you cant use it) holds you back from inventing something completely new or different to what has been patented ? Well.. I don't even ... where did you buy your logic? Take it back , get a refund. Patents can hold back your ability to improve exsisting technology and being able to sell that as a product but im pretty sure the patent holder would pay you a nice sum for your improvement ideas(if you patent them of corse). Patents can work with improvement and if what you are doing is really innovation , there won't be an existing patent anyway.  So please , understand a word before you create a "buzz-phrase" aro
