Has anyone found a good pinball emulator that will work on the Pi 3? I have an old laptop screen I want to re-purpose. I was thinking the aspect ratio would make a great little tabletop virtual pinball machine. I haven't found anything for the Pi.

Just a note, PiTFTs don't work with emulators using OpenGL ES (which includes almost all emulators). PiGRRL ( https://learn.adafruit.com/pigrrl-raspberry-pi-gameboy ) and Cupcade ( https://learn.adafruit.com/cupcade-raspberry-pi-micro-mini-arcade-game-cabinet/overview ) only run MAME and NES, so if...

You could cut the tip off, connect it directly to a step up transformer, and take power from a 5V GPIO pin. Guess it depends on what your project is. I am using the same screen for a portable. It really only takes about 6V (I forget the exact number) to work.

I wonder if that's the experience of most people. The case is really tight (and this is my first project like this) so the more simple the better.

Thanks for the fast reply. Looks like this one will work best for me.

I'm in the process of building a Raspberry Pi portable. I'm just wondering how others are shutting down the devices. I heard that just killing the power will ruin the SD card sooner or later. Any elegant solutions?

I've seen the episodes you are talking about. He builds some crazy stuff. Didn't really have everything I need but it was a real nice device.

It turns out that you can run the R-Pi by itself on 3.3V by simply connecting a regulated 3.3V supply to both the +3.3V and +5V supply rails (that would be GPIO pins 1 & 2, along with a ground pin). BUT that means there is no +5V for any USB devices that might need it (some do, some actually do...

I'm working on a portable pi. The case is really small and space very tight. I would like to use a 7.4v battery to power it. (I realize I need to step down to 5v for the Pi). I would like to find a micro usb charging circuit but have not been able to so far. If it does not exist will a 3.7v circuit ...

how are you powering it off?

This site has some info. It's meant more for gaming portables but it has some good info.

Ben Heck on the appropriately named Ben Heck Show on Revision3 also discusses making cases without a 3D printer.

I just started a similar project to make a Gameboy game emulator. Boy is it a tight fan. I have the SD card set up (mostly), Gameboy gutted, and the pi slimmed down. I need to figure out what to do for a power switch to safely shut down. I'm also not sure which way to control the buttons. I need the...

I appreciate all the replies. I wouldn't want this to be too easy. It seems like the PI can power the amplifier on the Sony speakers suggested. I'll give it a try. I sense a lot of trial and error coming.

I'm trying to stuff a Pi into an original Nintendo Gameboy case to make a portable Mame device. Most of the parts are on order. I would like to add a speaker to give the option of headphones or external sound. I found several similar projects but none that use a speaker. This is all new to me and I'...
