Portable Game Handheld

Hi,

maybe this is of interest for some of you.
Some weeks ago the retailer "Woolworth" here in Germany sold a handheld game for kids with
a small colour LCD and USB plug for 1 Euro (1,5 US$) .
I took one home and had a look inside. After posting it to the mikrocontroller.net Forum people all started to run to Woolworth to get one [noparse]:)[/noparse]
We found out mostly all infos regarding the LCD and the rest of the hardware.

www.mikrocontroller.net/topic/146804#1366349

The handheld is sold under the name "Miuchiz".
You can get one easily from Ebay, starting at 5$.
The problem is, the version sold here is the "Miuchiz 2.0", a redesigned clamshell version for the european
market.
I dont know if the hardware of the V1.0 sold in the US and elsewhere is the same.
If so, you can easily put a Propeller inside and get a 10$ portable Propeller handheld game [noparse]:)[/noparse]

In the german forum a guy designed a new PCB for the Miuchiz using an AVR CPU

Here a videoclip showing the AVR streaming "The Simpons" intro from a SD card:

but you could also just cut the traces on the PCB and solder wires to the buttons / LCD connector / speaker.

Info on the LCD :
98x68 pixel 65K color STN
8 Bit Microntroller interface
Integrated ST7626 Display Controller (easy to program)
only one 1uF C needed externaly
2,7 - 4.0 V
Pinout:

The original firmware is also hacked atm [noparse];)[/noparse] (the handheld uses a highly pimped 6502 clone CPU)
First demo showing code injected into the original game (bouncing square replacing a minigame normaly there):

    That looks really interesting. Thanks for the info.
    I'm going to look for one myself.

    That actually does look like a nice hacking project... I·like the 8-bit interface. I bet you could find the bare LCD for cheaper, but if you do want the case with the buttons (and presumably battery holder and speaker), then I think it's a good deal.

    Looks like somebody has already done the work of figuring out the pinout.

    Screen resolution limits usefullness a bit, but you can still do a lot with that...

    I think the easy way would but to use the existing circuit board, cut the logic traces to the LCD and try to wire them to a cut up protoboard or something and stuff it in there... Think there's room for that?
