What I already did with my Pi?
Movie ceter ✔
Small router ✔
Network shared disk ✔
Gaming station ?
This last one was quite interesting. Raspberry Pi spec says :
SoC: Broadcom BCM2837
CPU: 4× ARM Cortex-A53, 1.2GHz
GPU: Broadcom VideoCore IV
RAM: 1GB LPDDR2 (900 MHz)
Networking: 10/100 Ethernet, 2.4GHz 802.11n wireless
Bluetooth: Bluetooth 4.1 Classic, Bluetooth Low Energy
Ports: HDMI, 3.5mm analogue audio-video jack, 4× USB 2.0, Ethernet, Camera
Is it enough for gaming? Yes ! Thanks to https://retropie.org.uk/ we can use our Pie for emulate Amiga, Nes, Sega,Comodore 64. And many more! This page can help yo build your retro Pie from the scratch. But believe me it is quite painful. So I decide to use short cut. It means ready build images for raspberry pie . There is many pages but I found something really cool on http://www.arcadepunks.com . Ready made roms with all needed things. Now just download the rom and write it on to SD card.
But it was not enough for me , I wanted more. I’ve ordered new Pi case in Amiga style ! https://retropicases.com/
Buying case – soldering the wire for power off switch – installing fan
Ok Case is delivered, next is power button about I was missing for. It will save your SD card when your controller will not work, emulator will don’t go back to the main menu, or you don’t want to use second computer to shut down your raspberry via SSH.
I’ve installed power switch – Borkin Button . For me it was the best method , and very elegant :P.
What we need is Klick Quick Button known from android phones where numbers of pressed button were recognized differently by system app. For us it has to only send 0 or 1 signal for Raspberry , where small script will be wait for signal (and perform switch off ) .
Every thing is explained on this film made by great guy ETA PRIME , you should look on other movies from his channel. A lot of useful knowledge.
Small tech skill will be required when we will soldering wire between PIN 5 and audio out . Script from movie must be installed, to make this button work
PINOUTS (How to read pinouts of raspberry pi – when top of the board is at front of you, USB sockets are on your right side then pins are on top left corner . Then you start counting from left, pin on bottom is your pin no. 1 )
For cooling I used spare fan for Galaxy video card . To keep all i one place I’ve used hot glue, So in this position fan is not blowing but taking hot air outside of PI.
The same diagram you will use for connecting 5V to the fan , you will use pins 4 and 6 . One problem is with fan connected to those the pins. Will spin even when raspberry pi is switched off. Why? Because pin no. 4 is on 5V powering rail , the same like micro USB socket used for raspberry powering. It should be fixed by installing small transistor , but I have to figure it out later. Yea I could connect to USB , but it would be a wasting of the port.
And what next I copied image downloaded from http://www.arcadepunks.com/ and I tested for few hours . O sweet back to the past !
Cannon fodder, Sonic and many more !!!
