Parts List
- Altoids tin (I don't think size varies between countries, but the ones I've been using are from the US). You can also use the blank tin that Adafruit sells, as it's an exact match in size and shape: https://www.adafruit.com/product/97
- Raspberry Pi Zero W (the older non-W version will work fine, but wifi is very nice to have for transferring roms and SSHing into it to tweak settings, since the USB port is taken up by the sound card)
- 3D-printed parts to hold everything in place (I'll have those available soon. STL files will be available at some point in the future.)
- Screen: either the 2.4" screen with custom PCB that Helder will have available soon, or a 2.2" ILI9340-based SPI TFT screen like this one:
http://www.ebay.com/itm/252135075697 (It should look identical to this one on the back. You may be able to find cheaper sellers. There is a thread for discussing screen options here: http://sudomod.com/forum/viewtopic.php?f=30&t=2887).
- USB sound card (this one specifically because of its size and the fact that it puts out enough juice to not need a separate amp to drive a tiny speaker: http://www.ebay.com/itm/112304879364 -- again you may be able to find a cheaper seller)
- Speaker: 20mm diameter 0.5W 8Ohm (this is the one I used, but any 20mm speaker that is 3.5mm or less in thickness should work: http://www.ebay.com/itm/122331730209 )
- Charger: Either the Powerboost 500C from Adafruit (https://www.adafruit.com/product/1944) or a tiny battery charger like Adafruit's microLipo (https://www.adafruit.com/product/1904)
- Battery: 1200mAh lipo from Adafruit: https://www.adafruit.com/product/258
- DS Lite buttons and conductive pads (DSi, 3DS and n3DS will NOT work with the 3d-printed parts or the button PCB that we're working on. I will have white and black buttons available.)
- Power switch: (I used this one since it's available locally for really cheap, but any tiny switch should do: https://www.adafruit.com/product/805)
- Tactile switches: 2 for start and select - these 2 will be pre-attached to Helder's board - (2.5mm tall including the actual button, 2mm tall without, 6.2mm x 6.2mm base), and 2 for L/R (5mm tall including the actual button, 3.2mm tall without, 6.2 x 6.2mm base)
- If you want to do it all by hand in stead of using a button PCB, then some copper tape like this: https://www.amazon.com/Copper-Conductive-Adhesive-4inch-36yards/dp/B01CH4LYZ6/
Software
- RetroPie (the Raspian-based bundle of emulators and frontend we know and love): https://retropie.org.uk/
- fbtft (SPI screen driver): https://github.com/notro/fbtft/wiki/LCD-Modules
- fbcp (copies the framebuffer to an SPI/GPIO screen): https://github.com/tasanakorn/rpi-fbcp
- Retrogame (turns GPIO into keyboard input): https://github.com/adafruit/Adafruit-Retrogame
A pre-configured RetroPie image will be available soon.
FAQ
Does it have L/R buttons?
Yes π it π has π L π and π R π buttons.
Where are the STL files?
They will be released soon. See this thread for more info: http://sudomod.com/forum/viewtopic.php?f=30&t=3181
Can I use a 2.4" screen on a board, like the 2.2" version?
No, the board is too wide, even if you were to chop off the corners.
How will you put ROMs on it without access to the SD card?
This is why the Pi Zero W is so nice - it has built-in wifi, so you can transfer files and update settings that way.
How much does this cost?
Depends where you buy your parts. You can use the links in the parts list as a starting point and may be able to save a few bucks by looking around for better prices.
Can a 2000mAh battery fit in there?
Not the Adafruit one, no. If you increase the height of the bottom area of the tin very much at all then your buttons will be pressing against the screen, and that's not good.
Can I just buy a pre-made one?
I (wermy) will likely have a few for sale, but not many. I'm sure there will be others selling a few pre-made ones here and there as well, just like the Game Boy Zero.
