It must be the 1.8V.
Anything larger and you are likely to burn out your kindle.
Also get a soldering iron designed for small electronic work.

Thank you I learned the hard way, I plan on using a soldering iron at my university better suited for these things.
I thought the resistors could be used to convert 3.3V to 1.8V.
I realize I can't use the 3.3V as is on my pi because the kindle needs 1.8V.
Let me get this right. The 3.3V from my Pi is converted to 1.8V and combined with the RX from my pi. All this goes the TX of the kindle.
The RX from the kindle is converted from 1.8V to 3.3V and sent to the TX of the PI.
The diodes are to stop voltage from going the wrong way and the ground is the ground.
