Homemade "headlamp" like Project needs IC spec

[thenewguy]

I trying to build a very simple inexpensive circuit for a led project.
1st: ON- HIGH 8 LEDs (5mm) LEDs
2nd: ON- LOW 4 LEDs (from the original 8 white LEDs)
3rd: ON- FLASH 4 red (5mm) LEDs (blinking)
4th: OFF

I bought some cheap lights that had this same function and ripped them apart to see what I needed for parts. I've attached some pictures of what I found but there is one part that I don't know what it is. What is that component, and where can I easily buy them? thanks

ahorton mentioned an IC does anyone know what kind would function like I want above?

Re: Homemade Switch

I think that blob is an integrated circuit built straight onto the pcb and protected with a blob of epoxy.

You can buy a range of integrated circuits and microcontrollers from most electronics stores.

I know it's fun and all, but apart from that I don't really see any point. http://www.dealextreme.com/details.dx/sku.5660 is pretty inexpensive, you've got to admit.

Re: Homemade Switch

I need to some reading on IC's. I soldered on some regular white leds where my samples had blinking red ones, the white led blinked as well. I can go with the 3 position switch and blinking leds or trying and figure out an appropriate ic that will configure my light as needed.

Any intro to IC websites or books someone can recommend?

Wikipedia is a good place to start.
