Update: Tetris Handheld Get PCB and Case

update-handheld-tetris

Check out this sweet-piece of homemade handheld gaming! [Jianan Li] has been hard at work on the project and published the updates in two parts, one that shows off the PCB he had fabbed for the project, and another which details the 3D printed case. This is, of course, is the culmination of the Tetris project we first saw as an incredbily packed, yet thouroughly tidy breadboarded circuit.

We really enjoy the 8-sided PCB design which hosts all the parts and gives you a place to hold and control the unit, all without seeming to waste much real estate. The case itself is quite impressive. The openings for the square-pixel LED matrices (the original design had round pixels) and the bar graphs all have nice bevel features around them. The control area has a pleasant swooping cutout, with blue buttons which stand out nicely against the red. Check out the slider switch by his left thumb. He printed matching covers for this slider, and the two that stick out the bottom. Also on the bottom are female pin headers so that you don’t need to disassemble the case to interface with the electronics.

All of this and more are shown off in the clip after the break.

    The First project done by a muppet, loose the gloves dude.

    other than that, cool project.

    very nice

    What is the deal with the gloves?

    This is just begging for a gray Plexiglas overlay. Would help tremendously with the legibility of the display – and should reduce eyestrain to some degree as well.

    put some shaded plexiglass on the LED displays. they will be much easier to read and look better. (especially on photos :-)

    I couldn’t find any suitable plexi, so i’ve used scotch tape coloured by black sharpie (not too much) and it’s much easier to read now… however it doesn’t look “pro”. it was just quick fix to improve readability of voltmeter of my diy bench supply.

    While I sense a Germanic accent (Swedish? Dutch? Amish… no that’s silly) is it really so cold he has to wear gloves? Dude, your a good hacker, hack up a friggin’ furnace!

    This is phenomenal. From his blog, I see that he’s only been working with microcontrollers for not quite a year. It looks quite professional. Good job! I definitely need to up my game.

    (And all that some people can comment on are the gloves … really?)

    That should be “Update: Tetris Handheld Gets PCB and Case.” Subject-verb agreement: it’s not just a good idea, it’s good English grammar.

    This is a beautiful build. Great job!

  10. Very nice work! Nice PCB layout for you first time, great job!

    When I saw the video, I knew that casing was done on a Stratasys. You confirm it on your blog.

    Beautiful project. Gloves? I’m not even wearing shoes :D

    A first class example of what can be done by a motivated person with CAD/CAM design tools and rapid prototyping these days… software, circuit design, PCB design, and enclosure design. Well done!

    I just saw him on Adafruit’s Show and Tell this past Wednesday, and it was an awesome project! I’ll put a link below for anyone who wants to see it.
