ppl any comment?!!

which kind of transistor and how it's connected in details? i see a capacitor and a resistor on the transmit side and a resistor on the receive side.

As well i've this ECG electrode http://store.fut-electronics.com/ecg-electrode/dp/1188 , but not sure if it can help in the signal strength issue and if yes how to connect it to the Mindflex...

steeph-k: which ThinkGear module, i'm using Mindflex and it has neurosky module with TX and RX already connecting the Tx to Arduino Rx and GND to GND
