I really like a old games like Final Fantasy, Sword of Mana, GTA:LCS and many others! So i wanted to buy a some console, but its cost a some money and i cannot play a games from other consoles, so I get idea to create a myself handheld game console!
For first I needed to select a device, so I chose a Raspberry Pi 2, because I want to play some PSP games. Then next I need a display etc... Because I dont have a so much money, I tried to find a cheapest items, so eBay!
Before I write a list of items what I bought, first I will write what items is needed and what is it usage.
So, I selected Raspberry Pi 2! Next we need a some display to draw our games! I searched in eBay a 4,5 inch parking camera into cars, its cheap!
But we need "feed" display with "energy". Display need a 12V, but from batteries we can get only 3,7V or 7,4V etc. So we need a DCDC 12V convertor, when minimal voltage is lower than 3,7V and effectivity is more than 90%. Next we need a batteries, for now I dont know what batteries I use, and I got some batteries at home, so Im taking this to later. Well, of course we need a sound! So some speakers. I use a speakers from my old laptop, so it isnt in my list of bought things, but we need a Stereo Amplifier. And now the gameplay things. I want to use all components whats used in PS2 controller, so two thumbsticks and 14 buttons (i bought a pack of 20 big buttons with plastic headers).
For connection of thumbsticks, buttons and other hardware things we need an Arduino (or Atmel chip). First I wanted to use ATTiny, but because its expansive (and maybe USB HID is not supported, but I think its supported) i selected a Arduino Pro Micro, what is cheap, small, but we dont have enough pins. For this we need IN 8-BIT Shift Register, probably CD4021, I will buy it in a "stone store", its cheap. So we got +6 PINs. For connecting a Display and Speakers, we need to buy an 3,5mm 4 pole Male jack, + 2 "pins" from RCA cable (connection of display) and some wires into a sound amplifier.
I think its all about hardware, but anything can be changed while building.
There is list of items what I bought, soon I will add a eBay links and costs:
- Raspberry Pi 2 (30€)
- Analog Display (10€)
- DCDC Convertor (1,16$)
- 2x Thumbsticks (3,98$)
- Arduino Pro Micro (4,30$)
- 20x Buttons with plastic fields (1,99$)
- 3,5mm Male Jack (1,89$)
- Audio Amplifier
And some others things. Some things I got home, but its not a expansive things!
Fully I paid +- 50€ for all!
Next I need to setup all electronics, make a 3D case model and found someone who will print it!
And now, just waiting to items arrive!
Step by step I will write a articles about things I do, so dont forget to check my blog!
