Step 3Soldering it together
This should be pretty straight forward.
Just follow the schematic, and everything should work just fine.
If your soldering skills are a bit rusty, of you're a beginner, there are a lot of good How-To-Solder guides here on Instructables! Be sure to check them out if you're unsure about soldering. Don't let bad soldering ruin this (awesome) project for you.
When you're soldering, be sure to note the D+ (Green) and D- (White) on the USB cable. It's very important not to mix those!
Here's the pinouts for various USB connectors.
Also, if you do I like I did and solder the wires directly onto the LCD display, be very careful to not make any bridges between the connections! The connections are very small, and trust me, it's not fun when you realize the only problem with your circuit is a bridged connection on the display.
Here's a bigger version of the schematic.
Again, here is the datasheet for ATmega8.
