Voltage Issues

One of the hassles with this and the Arduino is that the arduino is 5V and the nRF runs at 3.3v . There are a few carriers out there, but i wanted something really small and easy. So I'm using the voltage drop across a LED to power this. You'll need one of the normal size LED's and they drop just under 2v and also provide a visible indicator as it will pulse as the nRF goes about its business.
