Hello
I would like to show you my first DIY gamebuino "clone".
It is completely hand made and hand soldered (except SMD parts on pro mini and the programmer).
It is based on R0d0ts original gamebuino design and schematics which can be found on the wiki.
I also added some "improvements"(changes):
-larger battery (1000mAh)
-larger speaker
-blue backlight
-larger buttons (same ones used on arduino esplora board)
-a bit different Li-Po charger (Charger module with TP4056 controller)
-3.5 mm audio earphone jack
-SD card slot (not a micro SD card slot)
-LED (indicator) that flashes when sound is outputed to the speaker
-a few more switches which allow you to manually turn backlight in three states (OFF-AUTO-MAX), and to manually mute the speaker
I bulit it with parts I bought on ebay or unsoldered from old circuit boards. It is hand soldered on a proto board, and has a piece of plexiglass (also hand cutt) screwed on the back.
It also has an EXT1 and EXT2 port (i2c ports) which can be used to connect modules and other gamebuinos.
Between the two EXT ports there is a ICSP port, that can be used for updating the bootloader or connecting SPI devices.
If you look at the pictures below, you can see there are two micro USB ports, one is used for charging the Li-Po battery, and the other for programming.
Unfortunately the only thing that doesnt work (yet...) is the bootloader, I was discussing that problem in this post:

altough I can load files or even stream music from an SD card.
I am going to post some more videos and pictures soon.
