PlayStation 2 Portable Docking Base, RaspberryPi Game Console

Former Member
Former Member over 11 years ago

Hey,

 

Couple'o days ago, I've got my hands on a PS2 Slim. Later on, I've noticed that it's power supply produces only 8.5v and max ~5.5A I guess.. So I've got the idea: Why not make a portable dock with a 7" TFT, 2W8Ohm stereo speakers, and an AUX port? So I've started searching aound the interwebs and didn't find a thing about this, but seen this RaspberryPi stuff, and came up with another idea: How about making a gameboy-ish retro console out of this little thingy?(Probably gutting an NES controller would give the controlls) So I started searching again and found some articles, but nothing actually has been around my imaginations. Then finally, I've found it out:

What if I put these all together, and make this AV dock that's compatible with PS2, and also has a RaspberryPi (actually functioning as a retro emulator) inside? It would probably be propelled by a 12v battery, and have a "Mikroelektronika AudioAmp" for the audio.

 

I'm doing this only as a hobby, I'm pretty much of a rookie in electronics stuff. I'm asking here about this, please help me.

I've came up with this sketch:

1. Volume knob

2. 3.5mm Audio in jack

3. 3.5mm Audio out jack

4. Channel switch(external - internal / PS2&RetroPi - External)

5. Main power switch and power LED

Sorry for the poor picture, I'm not a pro with MS paint..

 

Please Ben Heck, I need your help!!

    What I actually need help with is converting 12V into 8.5-9V 5-6Amps. Any suggestions?

    Sounds legit, think I can handle that.. But I've seen these "voltage regulators" that are used to power an LM386 chip from a 9v battery by reducing the voltage, those would take less space and emit less heat.

    Anyways, the 8.5v should be for the PS2(Slim)

    Thanks for any feedback/help so far!

    Any suggestions for the battery?

    Yeah, that would be a linear regulator.  I don't think you are going to put much current through those though. Worst case power would be (12V - 8.5V)*6A = 21W. 

     

    Even at 90% efficiency on the switching regulator you'd only see around 5W wasted if my calculations are correct.

    Yup, problem is PS2 requires 79W according to the Internet.

    I came up with the pre-beta parts list(missing pretty much stuff):

    Regulator/DC-DC Converter: http://www.aliexpress.com/item/DC-4-5-30V-to-0-8-30V-5A-Step-Down-Converer-Voltage-Regulator-Buck-Power/606392085.html or http://www.aliexpress.com/item/DC-Buck-Adjustable-Converter-DC-4V-30V-12V-to-1V-27V-5A-Step-Down-Converter-for/101882462…

    7" TFT LCD: http://www.aliexpress.com/item/7-TFT-Color-LCD-2-Video-Input-Car-Rear-View-Headrest-Monitor-DVD-VCR-Display-Monitor/1566…

    The small amp module: http://www.tme.eu/en/details/mikroe-234/development-kits-others/mikroelektronika/audioamp/#

    2 of these speakers: http://www.tme.eu/en/details/vs-bf45/speakers/visaton/2240/#

    The project also needs charger circuit, batteries, some buttons, switches, knob for volume, the power led, cables, and, of course, a RaspberryPi. Well, as you might notice most of the links are from AliExpress, and they sell stuff named Cubieboard there, that's the chinese RPi. According to this site(http://blog.bulte.net/01-09-2013/cubie-board-quick-look-raspberry-pi-comparison.html), the Cubieboard is nearly 1.5x more powerful than the RPi, but RPi is the original and even takes less space. So my question about this is should I stay with RPi or change plans for a Cubie?

    Also, I've found a voltage-amp meter for the battery: http://www.aliexpress.com/item/YB27VA-0-28-LED-Voltage-Current-Meter-0-100V-10A-DC-Red-Blue-Dual-Color-2in1/1198074622.h…

    Almost forgot: the RPi needs 5v and 2A, right? So another regulator circuit for that...
