After finishing drawing the sidepanels in AutoCAD i made a trip to Belgium today to¬†a company called ‘Lasertechniek N.V.’ (http://www.lasertechniek.com).
They cutted the 8mm plexiglass for me with a ‘Trotec Speedy 300’ CO2 laser machine (thank you Michiel).
I wish i had this machine at home ūüėČ

I’m very pleased with the¬†result. It is¬†absolutely flawless ūüôā
BTW: the mini cab will be: 16cm x 29cm x 20cm  

Here is a little video of the ‘Trotec Speedy 300’¬†cutting one sitepanel.

Size does matter ;-)

Today i received my ‘Space Invaders TV Game’.

I have disassembled it and i’m going to use the mini-aracde-joystick for this project.
The mini-arcade-joystick looks, feels and works like an original arcade joystick. 
It’s just a little bit smaller. Perfect for the mini-cab.¬†

BTW: I’m going to connect the mini-joystick and ‘Sanwa OBSF-24’ buttons directly to the mini2440 free gpio’s.

Boot-Time Optimization

Posted: June 7, 2010 in neo-geo minicab

I have done some modifications to speed up the boottime:
* cleaned/minimized the linux kernel to 1mb
* now using a uncompressed kernel
*¬†changed the ‘jffs2’ rootfs to ‘yaffs2’
* tweaked the ‘u-boot’ bootloader.

Boottime from turning-on the mini2440 to a linux console prompt is now 4 seconds!

GnGeo Port

GnGeo 0.7.1 has succesfully been ported to the mini2440!

ALL THE CREDITS GO TO PEPONE (http://gngeo.berlios.de). THANK YOU MATHIEU!

Plexi Bending Bench

Posted: June 4, 2010 in neo-geo minicab

I¬†just finished the ‘Plexi Bending Bench’ using these instructions : http://www.highflow.nl/forum/f11/plexi-buigbank-4527 It’s in dutch, but i think you will get the idea.

Background info

Posted: June 4, 2010 in neo-geo minicab

I got inspired in making a mini-neogeo-cab after seeing ‘Pocket Lucho’ making this briljant¬†‘pocket neo-geo¬†cab’¬†(http://www.elotrolado.net/hilo_pocket-neo-arcade-2-0-proyecto-terminado_1251492).
But instead of using a real ‘neogeo mvs board’, i want to use a mini2440 arm board & 5.6″ tft screen (http://friendlyarm.net) . GnGeo (http://gngeo.berlios.de) will be the NEO-GEO gaming¬†emulator running on the mini2440.

Copying exact the same look of ‘Pocket Luchos neogeo minicab’ would not be¬†very original. So, i decided to make the minicab completely out of transparent plexiglass.

So, where to begin?
Well, first i’m going to make a ‘plexi bending bench’ for easily bending the plexiglass. Using a ‘plexi bending bench’ allows me to bend the plexiglass without¬†getting any bubbles in the glass.
