I came up with this here
http://arduino.cc/en/Tutorial/ArduinoISPMy questions:
- Do I need to put a logic level converters between the wires as I'm going to bootload the Arduino Pro Mini 3.3v with my Arduino Uno(5V)?
The pins have protection diodes but the datasheet says the maximum voltage on an i/O pin is Vcc+0.5V so it's best to use them. it. A simple resistor divider will do for 5V->3.3V, for 3.3V->5V (ie. MISO) you don't need anything.
