Check if the display is operating properly with a 5V power source:- power the display with a different powersource than the rest of the system, e.g. a second powerbank or a 5V smartphone charger.- connect the signal and ground wires to the pi- power on the display- power on the gamepi- check if there are still problems

no labels needed. these switches are pretty easy to connect.this picture should help to understand how they work. when the button is pressed the ground and the signal line are shorted and that's basically the signal to the pi to do something.

I never said cutting off power with the switch is a proper way to turn off the device. I also power it off just like you said - shutdown the raspi from the retropie menu and then use the switch to cut the power from all other components. If you want to implement a better solution you can add a tactile switch to a unused gpio pin of the pi. when it's pressed the pi shutsdown. after the shutdown a transistor cuts off the power from the rest of the system.

- buttons L1 and R1 on the shoulders of the case- better button ducts - universal LiPo PCB/battery combo- stereo speakers- speakers in the front- minor improvements for better 3D printing

the display features a build in voltage regulator. it works fine with 5V or 12V.

holy cow. at least the hot glue fits the filament color :D Check out the updated version of this GamePi. It should cover some of your improvements. what's wrong with the keymapping btw.?

Check out the updated version of this GamePi. it's designed for separate powerbank-electronics and batteries (link in thingiverse description)

It's described in step 7.https://www.instructables.com/id/Arduino-LeonardoMicroATMega32u4-As-GamepadGame-Con/

1) Nope. The Arduion Pro Mini does a good job.2) As much as the size of your micro SD card. (thousands of games on a 64 GB card )3) Nope. All walls have are 4mm thick. 4) It fits in the butt-pocket of some jeans. Size is: 20cm x 8cm x 3cm5) As ergonomic as a thicker SNES controller (or a PSP). It's OK I guess.

finished the updated version:https://www.thingiverse.com/thing:2911881

Had no problems with my controller. Try swapping the controller data wires (withe and green).

well, no one's gonna stop you from re-configuring the setup - go for it.

it's not overclocked. it's getting warm but nothing near dangerous.

I've no experience with video via bluetooth. You should try it.

This article describes how it can be done.

the size of case is 20cm x 9cm

I did not measure the battery life time yet. My other device runs 4.5 hours on one charge - but it has a Raspberry Pi 3 build it. This one here runs a Raspberry Pi Zero which draws less current - so I think it should run around 6 hours on one charge.

1. The battery life is described in the third sentence. 2. You won't. But you can calculate it: - the capacity of the battery is 1350 mAh. - the charger delivers a charge current of 1000 mA. So technically it takes around 1.5 hours to charge it. But the charger won't constantly charge the battery with 1000mA. Just let it charge for 2 hours and it should be fine.

Thank you. To your questions:1.) The USB cable of the controller was cut and the single wires were directly soldered to the USB connector of the Pi (or to the test pads - for better handling). So it's like connecting the Controller to the Pi via USB -- but skipping the long cable and the USB jack. 2.) That was a typo. It should be "4. Remove the multimeter." I've corrected it. 3.) Yes, it's possible. This question was already asked and answered. Look into the commentens for the question of "Mr Joshua" 18 days ago. You could also connect further controllers via bluetooth.

- make sure all audio wires are kept as short as possible- make sure all points are soldered correctly- make sure you do not set audio to 100% within emulationstation (80% should be enough)- try setting disable_audio_dither=1 in the config.txt

Yes, you're right about the slid-in nuts. I used M3s squared nuts. It's up to you using washers - I didn't need them.

working on it

I've updated the link. M3x12 is too short. M3x16 should work.

Thank you for the vote.The performance depends on what emulators you want to use. I tried some games on N64 and PS1 - they didn't performed that well. Older system like NES, SNES, some Segas works just fine.

That's the battery I'm using.

I'm working on a revision of the GamePi 2 (ducts, shoulder buttons, new battery layout, etc.). it's quite low on my todo list - so no ETA yet.

there you go:

I skipped the volume control wheel because you can control it within emulation station and use button shortcuts (and there wasn't much space left). If you want to add one you should check Step 10 of my other instructable on the bigger GamePi 2.

@Millionaar: that's the way I did it too.

but the nintendo switch is way thinner then a raspberry pi hooked on a display ;)you do not need a splitter if you you use the official Pi 7" display. it's connect via DSI - so the HDMI port on the Pi ramains free for further use (e.g. a TV)

my very first handheld device was actually build around a 7" display. you can see it on thingiverse: https://www.thingiverse.com/thing:2785021There is no instructable for it since it was somewhat of a prototype (too big, too heavy).

thanks a lot.

sure. if you're interested PM me.

not as quick as it looks like :P these are all projects I started with a while ago but then lost interest or got frustrated with (e.g. the sound part on this build). Right now I just want to finish all of them and enjoy the upcoming summer weather. but yeah - glad that so many folks like the stuff. thanks again, btw :D

haha, talking about "favorable emulation station".thanks for the hint. I'll update the values.

thanks a lot and have fun building it.

Thanks for your vote.I've added the design featuring the external USB port: https://www.thingiverse.com/thing:2790453I can really say if all the fake SNES controller are 100% the same but I would think so.

in you picture all letters should connected. It like all switches are connected to the same ground line.

first of all thanks for the vote :)the charging is described in "Step 4: Wiring: the Power Circuit". On the first picture you can see a female micro USB jack. The wiring diagram says "female micro USB jack for charging the battery". You can shut down the Pi cleanly from the emulationstation main menu:press the Start button in the main menu, select QUIT, select SHUTDOWN SYSTEM

thanks a lot.

Thx. Don't forget to vote for it in the contests :P

you got mail.

The 3rd sentence of this instructable says:"It is powered by a smartphone Lithium Ion battery which lasts up to 3 hours (depending on the emulator running)."

thanks for the kind words. Actually this build presented here is my second iteration of this device. The fist one featured an internal USB hub and a external USB jack (see attached picture). I dropped the hub for this build since the Pi Zero W comes with bluetooth and it's super easy to bind it with some (for example) PlayStation bluetooth controllers for some multiplayer action. If you're interested I can send you the 3D model (stl file) with the external USB jack.

Thanks, again.

Thank you very much.

you could just use the unused composite video output of the pi.https://www.adafruit.com/product/2881

IMHO this quite a simple build but I am maybe the wrong person to ask.

the signals at the audio jack of the Pi would be spitted. There would be sound coming from the amp and from the headphones.

I've added a new back case which now supports a Intenso S5000 powerbankhttps://www.thingiverse.com/download:4808813

If we want to be super precise:Type: ScrewModel: ISO7380Socket: Hex Socket Head: Button Head Thread: M3 (3mm)Length: 18mmYou'll need a length of at least 17mm so the screw takes the whole nut .

The question for the battery life was already raised below - and answered. It lasts for 4,5 hours.

Did you installed Teensyduino next to Arduino? If so check the configuration (see picture)

Certainly you could use other battery packs. The only thing you have to keep in mind is that the min. output current should be 2A. Most of the cheaper/smaller packs only have around 1A or 500mA. This one ( https://www.amazon.com/dp/B071NP9PGR ) should power the Pi properly. Unfortunately the electronics of different packs won't fit the 4 holes for the "battery load indicator lights" on the back of the GamePi.

thanks for the appreciation. The 3D printer sits in an self-build 50x50x50 enclosure. When printing ABS you need a constant ambient temperature of around 40°C or the printed object will warp and crack. The foam is some cheap acoustic isolation foam. The printer is cheap so it's also noisy. I added the foam inside the enclosure to keep it quiet. I am already 3D printing (sometimes selling) parts to friends and colleagues ;)

Check out the picture of "Step 12: Wiring: Power". The top left micro USB jack i where you plug in the charger (5V micro USB, e.g. the same as you use to charge your phone)

Hast eine Nachricht.

Good point. I have an arduino pro somewhere around - gonna use it in the next version.

OK so I measured battery life using a camera filming the Pi while running a SNES game. The GamePi died after 4,5 hours.

easiest way is to swap the used HDMI display with a display which is using the composite video output of the Pi. So you could use the HDMI port to connected the Pi to your TV.

I tried acetone vapor on another version of the case - but it went horribly wrong. So I stayed with spray paint and sanding.

oh, man. I should have googled the name before :D

Thanks for the critics. This build wasn't really much about saving costs. Good point using a rear view cam monitor - gonna try it in the next (cost effective) build. I was thinking about a pi zero w in the first place but in another build ( https://www.thingiverse.com/thing:2790453 ) I noticed that PSX game are not running that well - so I went the the Pi 3.

Thanks. You can check the list of supported platforms here:https://github.com/retropie/retropie-setup/wiki/Supported-Systems

Video added.

yep, that's the right - somewhere around $160. As I said you can safe a good amount of money if you get the parts from ebay, aliexpress, or somewhere cheap.
