Let's blink an LED using the 555 timer ic. You can do all sorts of things with this chip but we'll be focusing on one of the easier projects to get started. By the end of the meetup you should have a working circuit that blinks an LED. You can use this as spooky ghost eyes, or inside a pumpkin. You can look further into the 555 IC and build alternating blinking eyes! After halloween? Use it as a fake car security system ;)

We'll also talk about other small gadgets and electronic kits such as the Arduino, BeagleBone and standalone kits. There are a lot of things to tinker with!
In the news: Apple just announced that OS X (Operating System) is now free as well as it's iLife and iWork apps. This is pretty big news and will likely encourage other OSes ahemWINDOWSahem to be more competitive with pricing. Good news for us!
