Where is that orange wire on the right going? The one connected to pin 2 of the chip.

Sorry its not very clear is it! Plus the colours dont match at the CP2102 end!!

Orange (pin2) > TXD on CP2102
Yellow (pin3) > RXD on CP2102

I rebuilt it following carefully http://shrimping.it/blog/shrimp/shrimpduino_bb_minimal/ and seem to have made some progress,  managed to program it a few times!

Programmed the blink sketch and noticed that the LED was flashing in a very non-uniform manner. Could the crystal be a bit duff??
