So, I believe I'll be getting an audio alternative and a 4.3" screen this next week so I'll start building from there. Not a full console, more like an extended Pi Case while I get the other pieces (Controllers, wires, jump boxes, everything else)
the audio alternative is super simple.
Considering most projects output audio into speakers and no option for a 3.5m jack, I was concerned, specially when I would probably power it with only 3 volts (exclusively using GPIO with jumper cables, and Composite to output) so I decided I'd go (for starters) with Headphones. Sure! I'd still need to convert composite to a reliable that. So I found this. http://www.ebay.com/itm/152032363921 It's a cable that can be found cheaper, I just didnt find one that could ship to me </3 so I hope it works marvelously cause I could use this to transfer to an amp normally.
So this pre-alpha build includes the following:
Carton for prototyping
4.3" Composite LCD (hopefully works with 5 volts)
10mAh battery (previously owned by me)
Normal USB Controller
3.5mm for Audio
Of course, I'll be building on top of this, but I can't wait to show you guys for any possible inspiration for any ideas
