Halfinator Build help!! (Newb)

Hope this thread is in the right section.
I have decided to build myself a halfinator, problem is, I lack the knowledge in knowing how to build it. I have yet to find a step by step detailed build to use as reference. I've seen some nice builds on here but most of them are dated and most of the parts used are not available anymore.
Now, if anyone can take the time and help me with parts and planning, well it will be deeply appreciated. I live in the states, if that's factor.
Type of build: Halfinator
Features : Solar powered, Bluetooth enabled, long battery life, And LOUD:D
