Step 2Design the power regulator
Now the IH13 takes 7.5V DC to power it so I needed to build a small regulator board to convert the 12V of the battery down to 7.5V. This hand drawn diagram shows the circuit.
I had originally wanted to have a lighter adapter for a GPS unit also but decided against it in the end (I am hoping the new iPhone will have GPS ).
Most parts were obtained at Radioshack. The LM350 variable regulator was purchased from www.digikey.com because I needed a regulator that would supply 2A or more.
