  • 3D Printed Case

    The 3D printed cases arrive and they fine but I need to redesign the case. I am a waiting for some buttons to arrive to do that.

    There are a few test boards I made without buttons but I did have one before the current with the Pro Mini on top of the board before I designed it upside-down, underneath the board and removed the large screen SD card socket for the current version. The ST7735, ILI9341 and (monochrome) Nokia 3310/5110 have the same pinouts and can be used.  I now need to get a Teensy.

    This is a almost a replicated version without the barriers. Sound can be enabled but slows the game down for this game. Color themes can be changed and will be used in future versions. I just wanted to get out a first version for now so I can write some other games.

    Ordered my first ever 3D printed design today for this project and due to be shipped later this month. Used gmax 3D modelling software (3DStudio Max Lite) and the cost for 3D printing and shipping was $40 for 2 units in black.

    The gaming system consists of a microprocessor running custom code to receive user game-pad inputs and produce color visuals and sound to suit video games.

    Step 1

    Any Arduino that can use the ST7735 TFT 160x128 display. Although they may work, this has not been tested with other displays but uses the Adafruit GFX library and the Space Invaders remake demo was designed only for 160x128 and tested only on this display.

Solar panels arrived today and read an fantastic article:

If it wasn't for this weeks deadline, I wouldn't have ordered 3D printed case so early. So I have taken the opportunity to send my design to printer and am excited to see the results, and that it will be ready for the next phase. I've modeled meshes before but had no idea how my design will turn out in physical form as I haven't design or printed anything else before.

There are also some solar panels and LiPo charger to arrive and I think it might be a good addition as it keeps in the frame of compact and portable. The TFT displays the proper brightness at 5V so I use a step-up regulator.

Oooh.. much nicer display than the ubiquitous monochrome Nokia 5110 - I think I might have to play with those...

You might want to pick up a 2.2" (LI9341) also as they all fit UNO shields with 5110 sockets.
