Hello guys,
i have bought some stuff from Dinsyarcade.com and have a old screen from a "Tomtom One Edition 3".

I have no idea how to attach the screen to the Raspberry board.
Neither i know how to charge the external battery. Do i need one of those "Powerbooster" boards? Or can i just attach the battery to the raspberry directly and charge it then over the onboard power input?

What i want to do with my build:
- Have a speaker and a 3,5 headphone jack and a volume wheel
- play the games on the big TV (probably just with the miniHDMI port on the Pie itself)
- Play on the go in the original "Game Boy" case


Here is a pic of all the parts i have so far.
Thanks in advance.

Best regards
Kim

Yes you will need a charging module, applying direct current without a BMS (battery management system) will 100% lead to battery burn/explosion/blow... and 100% not charge it !

You also cannot use that LCD unless you want to make your own PCB for it, you'll need to buy a new one (3.5" reversing screen)

Okay thanks i understand.
But wich LCD screen can i use with this PCB from dinsyarcade?

The button PCB is irrelevant in terms of what screen to use.

As Kite says you'll need a 3.5' screen with its own pcb. There are several out there.

I'd recommend:

These require no 5v modification and work just fine with non intrusive boards which saves space inside the shell.

The first two pics i posted is the PCB from the screen. But how do i know which contacts i need for AV and sound?

You cannot use that LCD, you need one that can take composite input, which that one can't (because it is a TomTom device, not a video player screen)

I found some pieces that i would order.
Could somebody explain whats the difference between the below charging modules?

Your first link is a module that will charge a battery, it will not output 5V to power the system, you will need a separate booster for that. Something like this:

The second link will charge a battery and output 5V to power your system, although, you are better off buying a powerboost 1000 charger, and not the 500.

What I would buy is this, it's cheaper and does the same thing as the adafruit powerboost, i have successfully used 4 of these and have plans to use a few more:
