NES-Pi + Custom Amiibo (sort of)

New weekend project that I made:
Last year I a got a NES case of a co-worker, I did’t know what to do with it, until now…

IMG_3365 IMG_3370
Empty case, only the top and bottom and the buttons.  perfect for a Raspberry pi project….
The last weekend I started printing heavy on my Anycubric Photon.

And it felt if i was making Amiibo’s

After seeing the second picture above I got inspired to make a new RetroPie console.
Needed to be RFID and controller…
Left the NES case and the semi setup  Right a working setup only no working code at that point.
Even the RFID would’t read the cards because of the SPI-PY  its sort of broken.

How to connect?
DIY-RFID-Doggy-Door-Circuit-Schematic-w_-LED_Fig1 6IW3b-1

First install SPI-PY (git clone then rolle back:

git clone
git checkout 8cce26b9ee6e69eb041e9d5665944b88688fca68
sudo python install

If you do that! Then and only then, you can get the RFID-RC533 working under latest Jessy or RetroPie latest build.
Then you can install the MFRC522 Library and start reading some card data.

To get it working the way I wanted was a pain in the @ss. There is some info on runcommand:

/opt/retropie/supplementary/runcommand/','0', '_SYS_', 'gb', '/home/pi/RetroPie/roms/gb/Tetris (JUE) (V1.0) [!].gb'

But no info on Scummvm and i wanted to launch Monkey Island 1 SE talkie version I made back in the day.
When the Talkie Mod came out.. Been looking for a console that could play those 2 new Talkie versions.
And ScummVM is vers 2.0 on Raspberry so it would work.

Here is a Video showing off how it works and change between Monkey Island and EmulationStation.

More detailed view of how it works: Look at the LED LOL

Some close up photo’s

A almost done, want to mount the RFID on top. I want to keep the opening to load maybe custom NES cartridges.

Made also new printed USB controller ports:

How to Script it?

I made  2 bash scripts and 1 pyton script (reworked its the RFID reader):

Only added the import subprocess so i can run shell code.

Change your UID to the card you want to use to boot a game. (my card is 221,107,213,59,88)

The Time.sleep(15) needs to be removed to boot the game quicker but left it in because want to try loading splach screen or something. The Led is to indicate if the game is stopt or not. Then it will boot EmulationStation again.
The python program stops but is been rebooted with EmulationStation.

The bash scripts:

This will kill EmulationStation and load the game

This will restart EmulationStation and my Python script will check for a RFID card

And to make it boot at run you need to make this change:

And for the skin i used the NES-Mini theme.

But it was missing 2 themes, i used ScummVM and the Oric emulator on my Pi.
So i made them download link below:
Download link: ScummVM.
Oric Atmos :

Download link: Oric Atoms.

The RFID fits perfect in the box that i made, now i can insert real NES cartridges 😀
So if i buy empty nes cartridges i could insert a rfid tag and load that game

Tried that and works ;-)
Tried that and works 😉

(cartridges and RFID tag)

Things to do:

Mount RFID on top case, make everything more durable.
Optimise the code, use some sort of database to use more UID’s and game titles.
Get more RFID tag’s, print more modes of old games… (open source Amiibo’s)

Remix 3D Model of Dreamcast VMU

I recently got a Anycubic Photon.

And you can’t change your infill so you need to use hollow models;
when you don’t want to use a lot of resin.


I found this vmu on Thingiverse by pcwzrd13:
Printed this for my self and looks good but want to try it on the Anycubic so i need to redesign it.


So I have been playing in ThinkerCad again result:

The VMU is now hollow and loose buttons  😀

Maybe I can fit a smartwatch in there have a cheap 10 euro watch laying around.

But lets print it first 😀

Old AR demo I made forgotten about until Pokemon Go appeared.

Some time back i tried the hole Augmented Reality thing and now that Pokemon Go is so popular

I remembered this project that i did below is a video showing a demo of the project that i did:

If you enable your Webcam in this flash app you can try it your self.

The X-wing will rotated on the Code and if you move it it will follow your movement.

Needs Webcam!

This code is used to display the xwing print it out or display it on your tablet or phone

Place it so the webcam can see the code
