Gamebuino clone in a mint tin

that is awesome.

that is looking pretty neat!

Yes great and you could maybe write a mini article to explain how to check the battery voltage on a gamebuino with the spec of the hardware used. I'm near sure that this hack could be fine for some of us as it's should be not too hard to do (even you have to make a hole on your beautifull gamebuino to put the 2 pin (female) header and be able to connect your voltage display.  

Inspired from the Raspberry Altoids tin console i guess ? :

The battery voltage check is a good idea.

The voltage checker was simple to add - it only requires a little soldering.
The header just needs to be attached directly to the battery leads.

I used a usb lipo charger module (TP-4056), so I attached the header to the battery leads where they contact the module (see pic below).

With the header in place, a lipo checker can  then be used - with the help of a couple of jumper leads. These lipo checkers are common amongst RC enthusiasts. There are many types - some just have an alarm, I've used one with a LED display.

The one pictured is one of these:

Hopefully that explains it well enough...?

Yes, tank you. Its really easy  ;) 

Hey, it's awesome! You should definitely make a Creation and tag it as "Hackbuino", "Cases" and "Classic" :)
