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:
viewtopic.php?f=7&t=526&start=50
altough I can load files or even stream music from an SD card.

I am going to post some more videos and pictures soon.

Thanks!

Recently I made my first module, it is a ultrasimple led module, that can be seen in R0d0ts gamebuino trailer. It is basically just two green SMD LEDs tied to A4 and A5 (i2c data lines) on EXT port. With this module you just get two more LEDs you can switch ON and OFF in your sketch.

R0d0t please look at the pictures and tell me if my EXT port pinout is right (I do not know since there are just schematics, and the board layout is not released yet....I would really like my DIY gamebuino to be compatible with future expansion modules you will release).

Take a look at my gamebuino SD audio streaming demo based on code from gamebuino wiki ( http://gamebuino.com/wiki/index.php?tit ... _streaming )

Thanks R0d0t, the music my gamebuino is playing is Ninja Tuna (windows 7 sample music http://www.youtube.com/watch?v=tCO4i2t-Aso ).
Please take a look at my previous post and answer my question about the i2c EXT port layout.

Sorry, I didn't see your question. You pinout is the same, expect it's mirrored (you'll just have to plug modules upside-down). I tried to used the same pinout than seeed and tinkerkit modules:

Thanks for your great help

What do you think of my ultrasimple LED module?
I plan to make a few more modules myself in the future, I found a small vibration motor in an old cellphone so I am going to make something like your force feedback (vibration motor) module.

If I build a DIY gamebuino v2.0 I am going to add different EXT headers, is this something like the pins you used on the gamebuino design: http://www.ebay.com/itm/10pcs-2-54mm-KF ... 5b02226a6c


oooh you embedded the video....
how did you do that?

Awesome sound Albert! (and I thought my cell phone speaker was good!)

I'm would love to be able to hook up to a server and multi-play with people for games (advanced wars!!!!!!!!!!!!) And for controlling devices (using GBO as robot/heli/airplane/lawn mower controller....)
