Today i show you how i build my ColourMM

First i have get a PIC24/32 dev board.
I get a empty one from techtoys ...

After that ... the hell started with soldering all the smd parts.
The most difficult was to put the 100pins PIC32 in place

And for info , i do it directly compatible with the UBW32 board.

Up to now it's OK ... but !
I don't have a box to put all the VGA,joystick,audio,buttons connectors

Solution was found when i see a old External IDE hard drive box laying on
my desktop

After made all holes and fixation , i finally put the whole thing in this box
who was exactly the size i wanted.
Then i started to connect all cables (they are allot !) and for get the power
i just use the 5v output from the Hard Drive box ... he he he ...
The 3.3v is made from the dev board then all was ok.
And then ... Geoff <-- yea the 'Guru' ... is coming with a new
maximite with colours , stereo audio etc !!!
I was falling from my chair just to think about open the 'box' and change
the connections , made a low pass filter for audio and add components to
be able to have color graphics

But it has go better that i have think and my ugly maximite is just
become the most ugly i ever see

here it is :

The MMC card is fixed under the dev board just with hot glue.

So , now ... i will like to see if someone have made a ColourMM
most ugly than mine

Cheers.

Darth.

Theory is when we know everything but nothing work ...
Practice is when everything work but no one know why ;)

Another ugly Colour Maximite.

This is my first prototype, I used it to develop most of the code for colour support in MMBasic.

I am still waiting for my SD card holder, still somewhere in the mail.
If you look close on the right side i have connected only the green 'color'.
One of my projects requires more screens and using the 3 color planes will enable me to do just that, after modifying MMBasic slightly of course.
Another usefull trick is to use the three planes as double or triple buffer for showing fast flicker free animations in one color.

The OLED is connected to a serial port. The OLED has a picaxe controller that is connected to the OLED with 8 bit parallel bus and has some default messages in its eeprom and also accepts some tokens as commands like 'cls', move position, scroll etc.

I don't think anything is too ugly, it starts to get that 'punk' look about it...

Here's my *Colour* UBW32 testbed...

For crying out loud, all I wanted to do was flash this blasted LED.
