Introduction: Raspberry Pi Emulator Console for the Backseat

Picture of Raspberry Pi Emulator Console for the Backseat

Scope of project: After building a Bar-Top Raspberry Pi retro gaming machine I determined that while cool I cant take it around easily as it weighs about 40 lbs and is the size of a large microwave. And while fun for the basement perhaps Arthur would want to play it in the car for the long drives back to his Moms house.

My original plan for this build was based off the Adafruit PiGRRL but I I wanted the ability to play the SNES and Genesis emulators. I figured I would just need to add a couple more buttons and it would be a peace of cake. I thought wrong.

Unlike my other projects I bought almost everything for this build. I used my 10% off coupon for being a pro member with Adafruit, I have to say their support forums are great and the benefit of being an Instructables Pro member was worth it just with the savings on that one order. I chose the the 5" non touch TFT with HDMI input however in hindsight with the finished project I would have picked a analog/composite display as the driver board and signal wires are easier to route then HDMI.

I wanted to build a Gameboy and wound up with a cyberpunk looking headrest console. But the build was fun and the end result works. I am sure Arthur is going to like playing games instead of sitting for 3 hours in the car. Ill include pictures from the failed project just to show that sometimes things don't go perfectly and that is OK.

Take a break put it aside then when you come back you may have the fresh perspective to figure out the problem that was driving you insane in the first place.

Oh and I am sure I am going to drive someone nuts as I will switch between Metric and Imperial measurements with equal aplomb. Some things are only mentioned in MM and others are only referenced in inches. I will try to keep it all in millimeters for accuracy but somethings are only sold with inch measurements here in the states.

Shall we get to building? This took me about 3 weeks of tinkering after I scrapped the first 2 handhelds, I started pretty much as soon as I finished the bartop.

*Further note* The finished console is a full raspberry pi computer. With the wireless keyboard and mouse, and the little 802.11n wireless chip. I can exit emulation station using the controller or keyboard then boot to a shell or X to join wireless networks get on the internet or code. As everything is sealed in carbon fiber and plastic the wifi is needed to load ROM's and updates.

Step 1: Materials Used and Tools Required.

This is super important. Carbon Fiber gives off extremely fine particulates when shaped with power tools.

It will trash your lungs and your eyes so protect them and make sure you clean up with a damp rag when you are done working with it.

I wore a dust mask and I was still blowing black snot the following morning. Sorry if that is a image you didn't want to think about but hey you only got 2 eyes and 2 lungs may as well protect them.

Step 2: A Plan Never Survives the First Encounter...

Picture of A Plan Never Survives the First Encounter...

See that nice wood panel above in the pictures?... yeah... The finished wood case was too big for Arthur to hold. I went back to the drawing board and decided on a SNES controller for it is the right mix of button layout for all the classic systems and it was smaller then the 6 button genesis controller. Since I was going for a external controller I decided that a pelican case would be cool for the housing and would look nicer then a wooden box strapped to the headrest.

The only reason I am keeping this step in here is to show off my fancy carpentry and that i was able to reused the template and my plan for the display for the carbon fiber face plate.

As we all know a bit of forethought to the function of a handheld will make or break the device. The Gameboy and Game Gear were super comfortable to play and one could use one for hours with out any adverse effects. The PS Vita on the other hand is a torture device. I really wanted to like it but no matter what I added to the vita I still wound up with numbness and cramps.

I was going to pay homage to the Gameboy but the 5 inch TFT that I chose changed the profile from the 3.5" Pie plate. The larger screen would have made the MAMEBoy profile a bit too wide.

To make the plans of the case I went old school. I broke out the pencils pens and paper, grabbed my rulers and went to town. I will eventually get around to scanning my drawings if someone wants to make a wooden one.

Step 3: Software Side.

Since I am using the software image from my Bartop I am linking to its software configuration here.

Using the win32diskimager I wrote my backup image from the bartop to this card so for detailed directions on how to configure the controls The steps are the same to manually assign controls or after you copy the image to the card you can edit the Retroarch config with the following mappings under input player 1

Open leafpad then open home/pi/RetroPie/configs/all/retroarch.cfg

Select+Start will exit the ROM
Select+LB will save
Select+RB will load save states

Scroll down in the retroarch.cfg to this code:

input_player1_joypad_index = 0
input_player1_b_btn = 2
input_player1_a_btn = 1
input_player1_y_btn = 3
input_player1_x_btn = 0
input_player1_l_btn = 4
input_player1_r_btn = 5
input_player1_start_btn = 9
input_player1_select_btn = 8
input_player1_l_y_plus = -1
input_player1_up_axis = -1
input_player1_l_y_minus = +1
input_player1_down_axis = +1
input_player1_l_x_minus = -0
input_player1_left_axis = -0
input_player1_l_x_plus = +0
input_player1_right_axis = +0

input_enable_hotkey_btn = 8
input_exit_emulator_btn = 9

input_enable_hotkey_btn = 8
input_save_state_btn = 4

input_enable_hotkey_btn = 8
input_load_state_btn = 5

Download your base image This is going to be about a 1GB or larger file so while it is downloading you can format and get your SD card ready for writing the image. The most current version at the time of this writing is V2.3

The second piece of software is the SD Association card formatter utility, this will ensure that the SD card is properly formatted to the SD association standard. This may prevent possible card corruption however I don’t know for certain. My thought is that if the standards org recommends it then it is the best practice. I have had better luck with this utility then the windows format utility for SD cards.

The last piece of software to download is the Win32DiskImager I downloaded my copy directly from source forge as they don’t seem to put any junk in their download. This utility will serve two purposes the first is to write the image to the card. And the second is to create a backup ISO once you have it configured the card to your liking.

I installed the win32diskimager using Win7 compatibility as administrator for it to work properly.

After you have written the image to your SD card insert it in your Pi and Boot it with a network connection keyboard monitor and mouse.

The software image downloaded above will boot to emulation station press F4 when it states that you do not have a input configured to drop to the terminal.

If you are using a physical network cable you can run the following in the terminal window if not startx and manually start your wireless connection then open a terminal utility.

The final steps are to Expand the file system to use the entire drive,

sudo raspi-config

You will need to perform option 1 to expand the file system to use the whole card.
Then option 8 for advanced options to configure the memory split to 256.

At this time you can perform a software overclock by selecting the desired level of overclocking, however remember overclocking is at your your own risk you may void your warranty.

I cannot be held liable if you Burn your Pi.

Step 4: Carvin the Carbon

Picture of Carvin the Carbon

The plate that I had I was extremely lucky with. It is the remnant of a 300mm x 100mm plate. and it just so happened to be the exact width and length I needed for the Pelican case. Unfortunately with test fitting everything I had to remove the inner rubber liner from the case so I will loose my waterproofing but it will still be super durable.

For the plate to work properly I needed to cut a panel out for the viewable area of the the display. I used the sketches made for the wooden face plate to give a template for the monitor. One thing to note To safely work with the cutter and dies I used a face mask eye protection and covered the plate with blue painters tape on both sides to prevent scratches. Carbon/epoxy dust will go everywhere so make sure you have a shirt on that you don't mind getting stained.

After taping off the plate and marking my cut lines I started at the middle and worked my way to the corners using a reinforced cutoff wheel with my Dremel tool turned to its fastest RPM let the speed do the work don't force the tool. If you don't get a straight enough line you can switch over to a fine grinding wheel to even out your cuts. A light touch is the key.

After cutting the display I slowly ground the corners round to match the radius of the inside edges of my case. Lots of trial and error then when I slipped on the last corner I ground a cable pass through for the coiled charge cable and the controller cable.

I drilled 2 holes for the power switch and a as of yet unprogrammed momentary button on GPIO25

Step 5: POWAAAAA!!!

Picture of POWAAAAA!!!

I suppose the next best step is to figure out how to power everything. The battery pack with the case and 4 cells took up just way too much space in the box. It is time to route a remote switch and give it a diet.

As I am using stripped down electronics, to prevent shorts I am wrapping exposed contacts and boards with electrical tape. It may look like crap but they will be hidden under the carbon plate.

The power pack uses a momentary switch to turn it on and off. one short press to turn it on and a long hold to turn off. I added 2 leads to a push button then soldered them on either side of the existing surface mount push button.

To cut down on the size of the batteries. I used 2 18650 Li-Ion cells salvaged from a laptop battery by desoldering the brass battery contacts and soldering the wires to the positive and negative of the control board. Then I wrapped the whole mess in electrical tape to prevent it from shorting out. If I were doing it again I would have used a purpose built circuit instead of reusing this one.

The coiled Micro USB cable is attached to the case with a bit of non conductive hot glue. The pack is mounted using a strip of double sided foam tape.

Power is supplied to the components using a "squid" Y cable. I used the cable for the display and cut it into 2 6 inch lengths. I then cut a Micro USB cable so that the Micro male end was a 6 inch dongle stripping the + and - Wires and added a 2 pin JST connector to slip over the pins on the amp. I twisted all 4 of the (red) + leads together and soldered them finishing off with some heat shrink. I then did the same with the (black) - wires.

Step 6: Shorten Up the Controller Cable.

Picture of Shorten Up the Controller Cable.

The USB SNES controller was a bit too long as it came with a 9ft USB cable. As the console is going to be on the seat back in front of my son, a 4 ft cable is more desirable.

After removing the screws that hold the controller make note of the colors of the wires, as the replacement or shorter cable needs to be soldered to the board in the same order.

To apply tension to the wires as I touched the iron to them I used a hemostat with my pinky finger gently pulling down, while my right hand melted the solder with the iron.

After all 4 wires are removed, I cleaned up the excess solder from the holes and pads with some desoldering braid.

Now that the holes are cleaned up thread the shorter cable into place and use a bit of solder to attach the wires to the control board then reassemble the controller ensuring that all button caps and rubber membranes are in the correct position.

Step 7: Mount the Display, and Cram It All in There, and Finish It Up.

Picture of Mount the Display, and Cram It All in There, and Finish It Up.

First I lined the back of each circuit board with electrical tape to insulate the contacts then affixed a pad of double stick foam tape to each board.

The display is held in place with a bead of hot glue along the edges to the carbon fiber plate. I then attached the driver board to the display with double stick tape.

The Raspberry Pi board is test fit into place routing the cables and ensuring everything will fit under the plate. The amp was located so that a pocket screwdriver can fit in the cable pass through to turn the resistor knob.

Hey it all fits. Test it out before gluing the top plate on then you are good to go.

Now that the glue is all set up, I gently coiled the controller wire and used a peace of Velcro cable tie to keep it coiled. Then I wrapped the charge cable around the controller and gently closed the lid to ensure that it would close and latch. After that I threaded a peace of elastic Velcro strap through the molded slots in the side of the pelican case and strapped it to the back of my headrest. I mounted everything into the box in such a way that the lid functions as a controller rest when it is in the car. The lid also props the display into an optimal angle if the console is used on a table top.

Thanks for making it this far. I hope you get something out of this write up. It was one of the most frustrating things I ever built due to the multiple design changes and rebuilds. If you have any questions feel free to ask them in the comments and keep on tinkering.

Step 8: Redux

Picture of Redux

Howdy y'all. Well this little update is to address an issue I experienced with prolong use. One of the nice little 18650 cells I salvaged from old laptop batteries decided to catastrophically vent. I got lucky in that nothing expensive got toasted however it was a just par for the course with this build.

So to fix the power problem I grabbed a switching battery elimination circuit for an R/C and a 2.1mm female power socket and got to tinkering again.

Parts eliminated from the main build

Push buttons
18650 USB power supply
18650 Li-Ion cells

Parts needed
3 Amp 5V UBEC $5 from hobbyking
2.1mm Female panel mount power socket (had)
Alkaline Battery Holder (had)

The cool thing about the Battery elimination circuit is that it can output 3A nominal with bursts of 6A at 5Volts DC and accepts an input voltage from 5.5-23VDC so noisy auto electrical systems should not be an issue. That and I can power it using alkaline dry cells in a battery holder or my bench top power supply. Through out the process I tested continuity for correct polarity after each connection and before plugging everything into the Pi/Display

I will also show the origami used to cram all this stuff into the box.

Steps to fix the power.

  1. Cut the USB connector from the wiring harness.
  2. Strip insulation to expose inner copper strands of the wire
  3. Prep heat shrink
  4. Solder UBEC power out to wiring harness and dress the joints with heat shrink
  5. Solder the power in to the 2.1mm socket.
  6. Remove the buttons from the panel as they wont be needed anymore
  7. Insert Amplifier shaft through one of the 2 holes
  8. Insert the 2.1mm power jack into the other

Test power up and reassemble.

To cram everything back into the box.
The Pi Goes in first followed with the HDMI cable looped twice. The driver board for the display is not affixed to anything but there is a 45 degree angle folded into the white ribbon cable to relocate the HDMI port along the long axis. As the bottom of the panel on my build is the one that is tricky due to the HDMI adapters ,I fit that side first. Then gently work the cables in the rest of the way in, ensuring everything is hooked up as I go. Ensure that the controller cable is routed through the cut out. Then snap the top edge into place. Power it up again and play a game, to ensure that you have video, audio and working controls, before tack gluing the panel back into place.

There ya go. More fails corrected and hopefully this thing is done for good.

I will also add that in hind sight I should have used some cardboard to mock up the display and give myself a template to cut. Cutting the display and then trial and error sanding was tedious and invited errors like the one corner that got turned into a cord passthrough. I could have really screwed it up there.

muhammajunaid (author)2015-07-19

Hi, With the total cost as much as $200, why not just use a tablet , having android as the OS it will give a wide variety of games and along with bing cheaper it will let you run many other apps for elders as well?

superhotdog123 (author)2015-05-31

hey, two questions:

1.Where does your audio come from/goto?

2.Why not use a ps3 controller instead for wireless/wireless controller in general?

Good questions, The audio is a little 3W stereo amplifier. Running to two little speakers I salvaged from a laptop. And this leads to the second question.

My son is 5, I wanted to make it as simple as possible for him while still fitting into a single pelican box. The SNES controller meets two needs. 1 It has to be simple for a 5 yr old to operate with small hands and none of the games on the PI B+ Ver1 require any analog input. 2 the SNES controller is just the right size to fit between the monitor and the lid with the cable bundled next to the controller.

Now on the Pi 2 that I use I use for the Living room emulator console has xbox 360 controllers. But that one will run N64 and PS1 games too.

Gerfri (author)2015-03-05

Very interesant!!

sonicalec (author)2015-02-21

Yes raspberry Pi b+

sonicalec (author)2015-01-27

xbox 360 ?

MoTinkerGNome (author)sonicalec2015-01-27

Unfortunately the Raspberry Pi does not have the OOOMPH to emulate the 360 however The display does have an HDMI input so in theory you could embed it into a 360 case or Embed the display into a pelican case or the headrest to play the 360 whilst riding in the back seat.

as far as the Pi think 16 bit and some 32 bit gaming N64 is right out.

sonicalec (author)MoTinkerGNome2015-02-08

no raspberry pi

MoTinkerGNome (author)sonicalec2015-02-09

Not yet. The Pi B+ just does not have the horesepower. Now the Pi 2 that was just released can run PS1 and N64 at full speed. But that is the state of emulation on the Raspberry Pi at this point.

sonicalec (author)2015-01-27

xbox 360 ?

12Samzo34 (author)2015-01-09

Just to say, I'm a teenager so don't kill me!
I'm just writing to ask, how do you power the screen?? Is it wired to the Pi?? Or is it wired independently to its own battery??
Thank you who ever is knowledgeable in this subject (or who can read!) and who answers this. Thanks again,

MoTinkerGNome (author)12Samzo342015-01-09

Howdy Sam.

No worries, I expected there to be some questions especially when I showed both ways I powered. The display I used was designed to be powered via 5v through a USB connection. The Pi, Display, and Audio amp all require 5v. So I brought them all to the 5v side of my DC-DC buck converter (in step 8) If it were a 12v display you could splice it in on the 12v side of the the power circuit with similar results.

With an external 12v hobby lipo going to a barrel connector I am also able to run the system via a AC adapter. I hope this is making sence to ya if not feel free to ask more questions and I will help all that I can.

Love games

Lennymasterrace (author)2014-11-15

I hope you win the Grand Prize GNome!

Thanks Lenny, It would be nice as I have been lusting after a 3D printer but if not it is cool I only entered the contests to win other stuff to make more stuff. I don't take anything out of the family budget for my tinkering and only allow myself $25 a week for fun money. That is the reason I tend to use lots of recycled and re-purposed components.

If I don't win no biggie. Ill just have to go like Johnny Cash and get a 3D printer one piece at a time. However even the runner up prize is a Tablet that I can use for my classwork. So I am happy even making it to the finals. :D

MoTinkerGNome (author)2014-11-05

OK Yet another note. Had it been available I would have used this display. For $5 more it has everthing going the right way and mounting tabs too so you can avoid the hot glue. Man That is a purty display.

Lennymasterrace (author)2014-10-29

May I know how you managed to fit the display with the connected boards in that small box?

Ok, After a stomach bug Friday and Saturday. I wrote up a quick addition to this build and what I did to fix the power after one of my 18650 cells failed. Step 8 should show a bit better how everything crams into the pelican case.

Oh I omitted the 5 button control panel that comes with the display. It turns on when it gets 5v and as I don't foresee adjusting color or brightness I didn't want to hassle with the buttons.

Good catch in hindsight I could have been clearer on that step. If you can wait till this weekend Ill pop it apart and get some better pictures of it all crammed together.

Sure, I backed all the boards with electrical tape so that they would not short out on the metal of the display mount. Then I taped the short copper cable with the adapter board to the back of the display as the copper cable is not very flexible. I the white ribbon cable was sort of folded at a 45 degree angle to align the HDMI port along the long edge of the case.

The Pi uses the 90 and 270 adapters to route the cable along the axis. There should be just enough room to clear the top of the adapters and get the panel to sit inside the lip of the box. If using a wood panel there should be 1mm or so of the 3mm panel to sit inside the lip I used 4 drops of CA/Super Glue to hold the panel in place in case I needed to pop it off later. The driver board is free floading inside the case and the pi has a bit of double stick tape as shown in the pictures.

Lennymasterrace (author)2014-10-26

How hard is this project on a scale of 1 to 10? Is it suitable for people interested in the Pi and are beginners?

Well the easy parts are the case, controller, display, and pi as they are all off the shelf components. I just tinkered with them to make em a bit smaller.

Cutting the face plate is wear the difficulty comes in. If you use light craft ply instead of carbon fiber things will go a bit easier. Hot and Super glue work well for adhering the panel to the pelican. I used just a dab of super glue at the corners to keep it in and pop it out.

With 1 being assembling Lego's and 10 rebuilding a carburetor I would say that it is a 3. If you can use a saw and ruler you can get this together. The software is well documented here and on the site for the Retropie image. Before the Pi I was a relative Linux noob. now I am a slightly more skilled Linux noob.

If you pick the display I used. cable will make your life easier. I was able to get mine to fit with out it but it was sort of like a logic puzzle. You can fold angles into the ribbon cable to position the driver board to make it fit better.

If you use a external battery pack with out hacking it into a all in one box thing It is even easier as the pelican 1050 is not that big of a case. The extra couple cubic inches will allow the full length of USB cable for the controller. Eliminating a step and one less hole, and the coiled charge cable.

You could eliminate both buttons as I was looking for hole position and since I had both holes I needed to put the power in one and fill the other with the black button since it was filling up a hole it needed to do something so I hooked it to GPIO's and will eventually code it to intiate a shutdown script but I have not started that yet as it is not needed. Select and start on the controller then Start agian then shutdown will savely bring it down with out possibly corrupting the sd card image.

The inside looks a bit cluttered, I think I would be fine with a bigger case. And if the buttons aren't necessary, that's 6 dollars saved.

This is true. however the next largest case does not have the molded in strap attachment points. The 1050 is the largest of the Pelican Micro series. the 1060 is a bit longer and a tad wider but is 5mm shallower and you need all the depth you can get.

JustinN1 (author)2014-10-22

Nice! This is some Ben Heck level stuff!

MoTinkerGNome (author)JustinN12014-10-29

Dude thanks for the complement. That guy does some awesome hacks and it is an honor to be catagorized with him.

Zaqq (author)2014-10-28

Ooh, I like it. Have you check out the Pi Emulator in the briefcase? That one was mine; however, I think yours is a lot better looking. Good job.

MoTinkerGNome (author)Zaqq2014-10-29

I like your design too. I had not seen that however, It is giving me a idea for a prototyping work case. Put all the components in the brief case with the break out board and display when it is time to pack it up for the evening close it up then the cats can't bat sensors around. That would give lots of room for divided parts boxes and tools also..... HMMMM

I swear my cats are building something. I find anti static baggies all over the house and parts go missing from time to time. I try to keep them out of my basement workroom but cats being cats they sneak in and go all ninja mode.

vinz3nt (author)2014-10-22

Just wondering, is this the 480 x 272 pixels or 800 x 480 version, do you have a link for this monitor?

MoTinkerGNome (author)vinz3nt2014-10-22

I went with this one as it is 5V DC

however finding a HDMI cable that is flexable enough was a pain. I went through all of the short ones I had and had to buy one for $10 off amazon.

I shot an tweet to Adafruit offering a suggestion.
"@adafruit This one is a freebie idea. HDMI ribbon cable ends. A short flexible HDMI cable would be awesome for the PI and your Displays."

They replied. @MoTinkerGNome Like this?

Had I known that cable existed I would have picked it up.

vinz3nt (author)MoTinkerGNome2014-10-22

Or here:

Same monitor can also be found on eBay, almost 50% cheaper

MoTinkerGNome (author)vinz3nt2014-10-22

I didnt want to think that I was spamming the board. So I went through and added links to the stuff I picked up or similar so that they could be grouped together. I have no affiliation with any retailer listed. I work for an insurance company LOL.

Adafruit also offers a 1 time 10% off cupon code for instructable pro members. If anyone is going to attempt to build this Ill give them a free 3 month code to save a bit on the pricer parts from adafruit.

Andrew Hannay (author)2014-10-22

I like the excuse that you built it for your son, he probably doesn't even like the retro games. An iPad would have sufficed. :-)

Nice work though and I'm slightly jealous as I wish I had the time to do this sort of stuff but family life gets in the way. It takes me months to do something like this and then I have to sacrifice the gym or cycling. Then my posts to Instructables is usually just the pictures as I don't even get the time to write it up.

No worries. Actually if you check out my profile pic he loves them. I built a bar top arcade machine as we were turning the basement into a family room. I showed him what I built and his eyes lit up. Then I introduced him to the Atari games I used to play when I was his age. And he has been digging them ever since.

I can dig it, life gets in the way. Unfortunately in the rural area we live in there is really not much to do out here. I tinker to pass the time and well lets just say that I really need to build up an exercise regime LOL.

Agree, you can't play the old classics on an iPad. I have got my son into the retro video games on my MAME setup and my Bride of Pinbot pinball machine, but he doesn't last long and slips back into watching YouTube videos of someone playing Minecraft. Checkout some of my hacks.

I have the C64 laptop is top notch. I just followed ya.

vinz3nt (author)Andrew Hannay2014-10-22

Not so, most of the young people I know really like these old games, a simulator on an iPad or Android tablet are not giving the same experience

vinz3nt (author)2014-10-22

Looks awesome! great idea for my kids although they are a little bit too young now.

In my opinion the HDMI image quality is far superior over the composite one so the extra efford or wiring is well worth it.

olivopiment (author)2014-10-20
Quite interesting project !
Could you show us a scheme of the electrical system ?

Olivopiment I found a picture in my dump of the wiring harness I made of individual cables. I put it in the POWAA!!!! step and labled where the ends go.

The electrical system is basically just a Y cable. The Audio Amp, Pi and display are all 5V, 500mA draw. The USB power supply that I stripped apart has a 2 Amp x2 outputs so the 1.5A draw is within spec on one. If it were not I would have just plugged something into the other output port

this is incredible! awesome job

Thank you.

Every gamer in the world needs one of these and an xbox version

Thanks, I think when i finally get access to a 3D printer I will have to make the Pigrrrl.

Thank you. Never give up never surrender.

xxlauraxx (author)2014-10-18

A nice-looking console. Lucky Arthur!

Also, I like that you included the bit about how you made the wooden case, even though it ended up not working out. It looked great, and it's helpful to others when you share your entire process. Iteration = learning.
