arduino mintia - game console in a candy box

by:Changda     2020-06-14
This Instructables shows you how to create the Arduino color game console using a small candy box.
MINTIA is a multi-purpose tablet produced by Asahi Group Food Co. , Ltd. in Japan.
The design of the candy box makes it easy to take out a tablet with only one when removing the lid, and you can see the video demonstrating how it works.
It even has many 3rd-square customisation
Leather case for MINTIA.
This candy box is very thin and the tablet socket is perfect for a micro USB plug.
MINTIA was only in his 20 s, and a micro USB plug was not born yet!
It\'s a coincidence!
I want to squeeze all the electronic components inside to see how much can be squeezed.
Asahi MINTIA page: Facebook Official page: empty MINTIA candy box, you need to consume all 50 tablets first: there is no room for the PThis console to place the boost regulator, so remember to use 3.
Arduino board Version 3 v.
The link below is Sparkfun Pro Micro 3.
3 V 8 Mhzref: \"96x64 SSD1331 OLED display board, the smallest and thinnest color display board I can find.
At first I wanted to come from the old phone with a Lipo battery as it was only 23mm thick.
But I found it without a protective plate and the terminals were hard to weld so I ordered another one.
343450 is a bit too big. I used 303040 in the end.
It claims it has a capacity of 300 and I think it\'s good enough.
This micro charging board uses the TP4057 charging chip, the LED is red when charging, and will turn green when charging is completed.
Used to change battery mode between \"charging from USB\" and \"using battery power.
8 SMD buttons, 4 navigation buttons on the left and 4 operation buttons on the right.
Used to hold all SMD buttons.
Used to connect all circuits. You can re-
Programming the Arduino board at any time, but if there are already runnable programs in the board, it will be more convenient to test speakers, OLED and buttons.
If Arduino has not been downloaded and installed yet: Pro Micro board is not supported by the default Arduino, please follow the steps below to make the Arduino Pro Micro board: modified Tetris game of joang Villa, to support Ucglib and Pro Micro board.
Since the screen is squeezed from 320x240 to 96x64, the brick is a bit too small and 1 block is only 3x3 pixels, but it can be played.
Here is the source code I modified: source ref.
: The main design is to place OLED (visible area)
In the middle of vertical and horizontal.
The buttons on both sides have the same arrangement, which is designed to support games that two players can play on this console, such as pong.
To hide the game console in the candy box, I keep the front and border unchanged.
I just removed the sticker from the back and put all the parts in.
This candy box does not use any glue, so it is easy to separate the lid with some force: PAfter separate the lid and align the Pro Micro board USB plug to the tablet socket.
Some plastic needs to be cut to install the board.
Place the thin multi-function PC board on the back cover and cut the board to fit the box and OLED board.
Stick the SMD button to the PC board with double sided tape and mark the button center point on the back cover.
Drill holes for buttons. I start from 1.
5mm holes, 2. 5 mm, 3.
After the surface is smooth, 5mm, 5mm and finally about 7mm.

> Pro micro panel button panel-
> The Pro Micro boardConnection details are displayed in the following steps.
Fix the Pro Micro board and Lipo battery with double sided tape.
Welding Details: After welding, plug in the USB power supply and the charging board LED lights up.
If you have programmed the Pro Micro board in the previous steps, the Speaker should play the Tetris melody.
Keep in mind that before welding, remove the coating at the end of the coated copper wire.

After turning on the power, the OLED should display a splash screen of Tetris.
Measure and paste masking tape according to design.
Drill holes, cut out the middle part and shape the boundary with the cutter.
Carefully check if the holes in the OLED Glass parts are appropriate.
Mark the switch and Speaker position on the back cover, then drill holes and cut holes.

You can listen to some click sound when the click is successful.
You may find the hole a bit ugly, don\'t worry, we can print a nice cover to hide it. Play Tetris!
Show your friends the front and flip it and show them what you did! What\'s next?
