I'll start with pictures. The cube should be a small and the first thing that comes to mind - likea elephant))
When I started I was nothing: cube, gamepad, memcard, display, buttons, triggers, mod mod chip etc. Almost all parts ordered from different countries, in my country gc - rarity.
Today I received my console and already break it. Dimensions motherboard 11,9x12,6Sm (Pic 2,3) I ordered a small 3.5-inch display, controller, tact switches and another parts. Having dealt with the power supply. It is possible to remove the 12v supply line, and replace them on the five volts. We save 1 wire and plenty of space. The power board will be beyond the console.
Disassembled joystick (pic 7-8) and controller board (pic 9). I will be use 3ds stick. Plastic case, controller board - no more needed.
Started working with the motherboard. No schemes and datasheet - too bad! Pcb has 4 layers and thickness - 2mm. Need make power line map and delete many components . Photos 10-11 Handy X-rays.)
On (pic.13) remapping supply lines, transparent overlay for making the necessary circuits (pic.14). (Pic.15) pinout picture. Pic.16 is a cutting board line. The last photo of my motherboard after partial cutting. There were problems with the board after cutting, 5v line was in short circuit , and all because I was too lazy and not accurate
In AutoCAD I started modeling accessories and components. Attach a photo 3ds joystick (Pic 19), memory card, display, motherboard - 90% of the components.
Few details: joysticks cpu, many buttons, wasp key cpu
(pic30) main board prototype - v1
Continued. Expected thickness between the motherboard and prototype board - 3mm)
all together v3
And v24 model
