I had to fight with this for a while but I figured it out and wanted to save everyone else the pain! If you're using GPIO for input (this may apply for the Teensy as well) and want to have a joypad connected via USB so you can have two players, you need to make a couple of edits to the retroarch.cfg...

Hey guys, I was doing my build a little bit differently and i was wondering if anyone could help me figure out on how i would be able to hook up this volume wheel with the raspberry pi zero http://www.ebay.com/itm/Volume-Sound-Speaker-Control-Wheel-Tools-for-Nintendo-Game-Boy-Color-GBC-ZVMA618-/291...

I believe I would connect R+ and R- to to my head phone jack with would match your amp's + and - connections. The 5+ and Ground would connect to the breakout board. What about A+ and A-? Not sure what this relates to for my amp? So for the Adafruit amp I just connected the left channel from the hea...

Done! Well, mostly. Some customizations over wermy's original: 640x480 VGA screen Better speaker Kept a large part of the original circuit board Kept original Ext Connector plug, but covering a USB port instead (see below) Kept original DC barrel jack for power and found a USB cable with that connec...

I've got photos and videos in another thread: http://www.sudomod.com/forum/viewtopic. ... 2347#p2347

A diode protects against voltage flowing back one way and it also lowers the the actual voltage flowing through it so not sure that's what you want. I was referring to power on the amp but if that's where the amp connects to then yes. Oh so you'd actually have it on the amp? I was expecting it to g...

Can you please tell me more about the sound card... were did you buy it and how its working?? It's this little guy: http://www.amazon.com/Sabrent-External-Adapter-Windows-AU-MMSA/dp/B00IRVQ0F8 $5 and works great! Just needs a config file set on the Pi and then it works like charm: https://learn.ada...

So no need for a diode in there, just a cap between PP1 and PP6 on the back of the Pi?

Having the same issue but had not researched why. Thank you and interested in alternate solutions as well! I would imagine a capacitor or two along the lines that power the Pi would be able to provide a little extra juice to cover that power dip while the amp starts up...but unfortunately my raw el...

So I've run into an interesting power issue...I've got the Adafruit speaker amp and it's ground wire runs through the headphone contact switch: plugging in headphones removes power from the amp completely so that it's not drawing power at all. The problem is that when I remove the headphones, and th...
