chiz's GB Pi2

[GnobarEl]

Hi,

can you share your config.txt please?

Thanks.

@GnobarEl
Which part exactly of the config.txt you're interested in?

*** Update #17 ***

Finally, after busting two (2) USB hubs, frying one USB gamepad board and lots of sleepless weekend hours, my GB Pi 2 is almost complete. Managed to mount today the battery connector and the LCD button controller board.

Battery Connector

I thought of mounting the battery JST connector in one of the sides in the battery compartment. This makes it easier to pull the connector if I want to replace the battery with a fully charged one.

LCD Button Controller

I mounted the LCD button controller on the other side of the battery compartment opposite the battery JST connector. This makes the button controller easily accessible by just removing the battery cover.

"Mostly final state" Shots

Here are pictures of the almost final state pending completion of the following:
1. Replace the sticky tack with double adhesive foam to secure the components
2. Add mini speaker - currently, audio works using the 3.5mm jack. I'm awaiting arrival of the 4-ohm and 16-ohm mini speakers that I ordered.
3. Replace screen protector with glass protector and mount permanently.
4. Add HDMI port - not needed at the moment but will be required to play 2-player games by connecting another USB gamepad
5. Optional: block areas with light bleed - I noticed some areas of the case that have lights bleeding. Not a show stopper but I like to address nonetheless.
6. Optional: incorporate Popcorn's graceful shutdown - right now I rely with EmulationStation's shutdown menu action then wait for the screen to turn off before I turn off the power. Works for now.[spoiler="front"][/spoiler][spoiler="top showing power and charging LEDs"][/spoiler][spoiler="left side view showing stock volume wheel and USB port"][/spoiler][spoiler="bottom showing stock 3.5mm jack"][/spoiler][spoiler="right side view showing micro USB power connector.

Joining its bigger "portable" brother: the PortaMAME

Adding this new baby to my growing family of retro and arcade consoles. Here are pics of my GB Pi 2 together with my PortaMAME portable arcade machine.[spoiler="PortaMAME full shot"][/spoiler][spoiler="PortaMAME controller close-up"][/spoiler]

Thanks Kite! I'm sure yours would be awesome once done!

I'm also following your work on the custom display and other boards you're making. Considering them for my 2nd unit.

I love the battery connector you have made chiz. Quality work

+ 1 for the battery connector.
Where did you find the "extension" cable ? Make it yourself ?

[toiletpaper69]

Very nice! Love the Portable Mame as well!

[chiz]

Thanks, guys!

@Robots86, @SidSilver
I had to order a set of 2-pin JST connectors for the batteries I took from the power banks. The order came with both male and female connectors so I made an "extension wire" with the male connector in the PowerBoost and the female connector exposed through the hole I made in the battery compartment.

Wow, this is really a great build! This battery connector is ingenious.
Do you happen to have the link for your JST cables?
I would love to have this connector, too. Only could find the cable so far.

@Fleder
Thanks, man!

I believe this is the JST connector I got.

@Fleder
Thanks, man!

I believe this is the JST connector I got.

This kind of connectors, could be used for more things than just plugging batteries, right? For example, to connect and disconnect the Pi and the screen, or whatever compound of your project?
