Step 5Teensy
Overview:
I think everyone agrees that Arduino has forever changed the landscape for DIY, makers, hackers, artists and engineers. It didn't take long after hearing about Arduino before I had one and was making LEDs blink and motors spin. But it took me awhile to realize there were other options out there, ones that were nearly identical to the Arduino (and in some cases better) but in much tinier packages... welcome to the world of the Teensy! (by PRJC)
What's a Teensy?
It's a small breakout board for an Atmel microprocessor, just like an Arduino... in fact they are so alike you can run a Teensy as a Teensyduino and use the Arduino IDE, making it easy to incorporate into any project. The biggest difference you'll notice between the two is the fact that the Teensy is way smaller!. The Teensy uses the 16Mhz Atmel 32u4 chip which has the nice feature of including a built-in USB port, which enables a very compact form-factor.
What will the Teensy do?
In the Laser Ball the Teensy will allow us to take the input signal from the IR remote through the IR reciever, decode the results, then sequence/animate the lasers. This is really a bonus feature (along with the IR remote), that really makes the laser ball an entertaining piece of technology.

Will the Teensy found on Dealextreme

do or I really have to buy from PJRC? I see some differences in design, maybe they differ in functions too?
How do I make this project sound compatible? You know, to make the lasers follow sound...
Thanks for the help, you really did a great job.

You can find Teensy's through other retailers but I believe directly from PJRC is the cheapest.
Adding sound is whole project in itself!.. but I'd start by adding a microphone. :)
I've ordered from PJRC. I'm also considering of building this into a more standard "box" rather than a ball. Is there any limit of how many lasers/IR receivers can I use? Can't decide how many modules to order...
