Here is a complete tutorial in 9 easy steps for programming ATtiny chips from Atmel using an Arduino. Fills in missing pieces from other online guides
Program an ATtiny Using an Arduino - [Link]
This handy breadboard header for ATTiny 25/45/85 microcontroller is a new design based on the original idea from Tinkerlog. Maybe the most useful feature is that it can provide power to the vertical breadboard strips while connecting all six port pins to the horizontal strips. Other features are :

These tiny controller boards are build to provide a quick start for projects with 8 and 20 pin AVR microcontrollers, e.g. ATtiny13, ATtiny45, ATtiny85 and ATtiny2313. They don’t include any fancy stuff, they are just as simple as possible. Eagle schematics are included.

Microprocessors are so cheap these days. If only there were a way to program them up just as cheaply… In this instructable, find out how to build up a complete AVR microprocessor toolchain: compiler, programmer software, programmer hardware, and some simple demos to get your feet wet. The endpoint is not quite as swanky as Atmel’s suite, but it’s gonna run you about $150 less and take only a little more work to get it set up.
This instructable is based on the Atmel ATtiny 2313 chip, mostly because it’s one of the smaller chips (in size) while still being beefy enough to do most anything. And at $3 a pop (non-bulk), they don’t break the bank.

With this small board you can program most of the AVR ATTiny microcontrollers or you can build your projects to use it in a stand alone application. It can be powered with a 9V battery because it has 5V voltage regulator on it. The voltage regulator can give 1000mA current. The power to the board can also be supplied with a wall wart. Low power external devices like a LCD module can be powered via the board itself.

alex_weber’s first Instructable is a cool one: an LED project that learns and replays sequences of light. Alex’s project is built around the Atmel ATtiny13v, an LED, and a Light Dependent Resistor-the whole thing is powered by a CR2032 battery.
