ATTiny Programming Shield for Arduino
This mini-shield is perfect for programming an ATtiny45 or ATtiny85s using an Arduino Uno as the programmer. This shield allows you to program multiple chips with the same sketch, without the need for jumper wires and a separate breadboard. This is sold as a kit with male header pins, 8-pin DIP socket and 10uF capacitor. The shield covers the two sets of headers near the USB port on most full-sized arduino compatible devices (power pins and pins 8-13).
Instructions on how to configure your Arduino as an ISP can be found here.
Make has a great video on "shrinkifying" your projects using an ATtiny45 or ATtiny 85 here.
