Hello, I am here, presenting you, another project, which is low in cost, that is easy to build. Zombies are attacking, and you need a way to defend against them, so you decide to build the zombie rifle to defend against Zombies. Overall, this project is a low cost, quick build. Most if not all of the materials, you can buy at Radio Shack, or Sparkfun. No, this project is not on an Arduino, because the next step of this project, is to bare-bones it. You will be using the cheapest development board known to man, it is by Texas Instruments; yes, TI is a calculator company, but they also manufacture cool development kits. The name of the Development kit is MSP430 LaunchPad; which you can order at the TI E-Store or Sparkfun, or really any other major electronics distributor. It costs about $6 by the way, and it comes with one of the chips you will use, and another free chip, which you can use for any other project.

This is a Zombie Game and it uses processing to create a GUI based thread. I used Processing because it is easy for anybody to use and I used the TI MSP430 LaunchPad because it is a versatile platform and also easy to use. I worked on this project, by myself, for about an hour. My plans and ideas did not change while creating the project, because I thoroughly calculated all of the needed resistances and capacitances, so there should be not problem. I made this at home, so I think that anybody could really be able to build this. I learned that it is always best to calculate values to my electronic components because it shortens build time and brings the cost down. The biggest challenge in this build was actually calculating the needed component values. I think that the only thing that I would change, when I do another build of this project, is embed a serial adapter on the board with the MSP430G2553 embedded, so that there would be no extra headers on board.

Step 1: Materials

You will need:
1 .01uF Polyester-Film capacitor
1 .022uF Polyester-Film capacitor
1 10K POT
1 22K Resistor
1 small Perf-Board
1 8 pin DIP socket, or 8 pin female Headers
1 Five pin Male headers (or just 2 pin male headers and one 3 pin male headers)
1 Button
Some wire
1 USB-B mini B cable 

<p>It looks veeeeeeerrryyy similar to the one I made, though I couldn't find any reference...:(</p><p>http://forum.43oh.com/topic/182-killing-zombies-with-the-launchpad/</p>
<p>Yes, I did use your game as a basis. I figured though that I could explain how to build this. I added a few things in the GUI on processing as well. Although you are right, you deserve credit; I will add your name to reference.</p>
Any chance of doing this with Arduino? I didn't even know this Lauchpad.. =P <br>Thanks in advance!
Video please?

You invented the game?
Looks interesting. Or rather intriguing, as I can't find a description of the concept of the game, schematics or anything on how it actually works. <br>I guess the game runs as a Processing sketch on the computer and somehow interacts with an LDR based &quot;gun&quot; built based on the TI MSP430 LaunchPad. <br>Nice details on how to build it, but not on what the different parts are needed for. You tell calculating the components was the biggest challenge, but you do not explain how you proceeded. <br>I do not want sound like a critic, but remember many people will not want reproduce what you did literally, but want to learn from it to make other things... <br>
Ok, for the calculation of the components, This article would be of some help if you want to learn how to figure out the capacitance and resistance needed: <a href="http://minerva.union.edu/labrakes/Capacitance%20and%20Resistance.pdf" rel="nofollow">here</a>. The idea of this project, is actually a test on the ADC port on the MSP430 based processor. It &quot;grabs&quot; analog values and converts them into digital ones. Think of the LDR as a POT, depending on the output resistance given by it determines the &quot;light colour&quot; and intensity. The Processing Sketch runs a very simple program which uses animated GIFs to be &quot;zombies&quot;. The reason for the total difference in colours, is so that the LDR can tell the difference between &quot;zombies&quot;. The whole protocol is actually quite simple, it runs USART (Serial in arduino terminology) to communicate to the computer. I will post some schematics, I drew them on paper, but I'll make a virtual version for clarity. Simon
This is a great project; the current price of the board is $9.99, but still cheap!
