After quite a lot of work, I have finished my GP2x mod.
I initially wanted to incorporate batteries into this system (see my BenHeck thread for project details), however I should have used Li-ions and not NiMH cells, and for some reason the GP2x was power draining powerful C cell 5500NiMH cells in an hour (perhaps it has a faulty capacitor?), which is awful. Hence, I am running the system off mains power. I have since got some camcorder Li-ions which I will use in my next project.
Components:
GP2x mobo
GP2x TV-out cable
PSone screen (5" - I find the GP2x screen a bit small), modded to take S-video
2 x 55mm speakers
12mm tact switches for buttons
Casing made of 2mm perspex
NES D-pad
Tools needed:
30w soldering iron, solder, desoldering braid, lots of wiring.
TI step-down regulator (using one PSone power supply of 7.5v, the TI card converts to 3v for GP2x)
12mm tact switches and 6mm tact switches
Dual polarity switch (on/off)
2 x 55m speakers
3 sheets of A4 sized 2mm perspex
UHU glue; hot glue, electrical tape
Mounting board and textured thick paper
Scissors, craft knives, pencils, paper, felt pens, black paint, paint brushes
Excellent TV-out program from boot
SD card
220uf capacitor (for S-video mod)
Thin and thick pliers
Dremel and various bits
NES controller
Buttons - flat, recessed, initially I wondered how good they would be, turns out they work great!
One thing I did which was rather clever (as well as the screen rotation itself), was to make the GP2x controls different depending on whether the screen was landscape or portrait; for example, in portrait mode Left on D-pad is Left but in landscape mode is down; and the A and B buttons change with the volume + and - buttons. I achieve this switch automatically by using rotating cotton buds, making contact with tin foil:http://www.dcemu.co.uk/dcemugp2xmod.jpg
