Any problems give me a shout.

Common failings -

you will need the 'ATTINYCORE library, the Tiny4KOLED library and the TinyWireM library

don't forget to 'burn the bootloader' in the Arduino IDE before flashing the sketch, it doesn't actually burn a bootloader but it does set the fuses - set the clock source to 8Mhz internal, then burn bootloader then program via programmer.

Happy fergelling.
