Product Review (submitted on March 11, 2013):

I burn optiboot using Arduino Uno as ISP. You can burn optiboot bootloader by using just 16000 hz crystal. What you'll need to put 16000 hz crystal between pin 9 and 10. Then load ArduinoISP sketch then upload, and then load optiboot sketch (select Arduino as ISP menu) then burn Bootloader.

I've tested that 18-22 pf Capacitor (2x), 120ohm, and 10Kohm resistor is not needed (can be omitted).
