    Chuck from Mountain King Technologies just sent me a laser cut acrylic enclosure for the PTP.

    I know I made it very difficult for him with the board layout... But, somehow, he pulled it off.
    As a bonus, it's also a 3D puzzle :), but it only took me 15 minutes to solve it...

    Anyway, great job Chuck! And thanks!

    That looks pretty cool. Is it for sale? Do you have a URL for Mountain King Technologies?

    Edit:

    I found it myself. I made a typo in my first Google search which is why I didn't find it right off the bat.

    Here's the URL:

    BTW: I've started looking into ways to use these screens with less pins...
    One thing I noticed right away is that the VSYNC and HSYNC signals aren't really used in the mode the driver defaults to: "DE" mode.

    Anyway, if you want to recover P16 and P17 for other purposes, use the the driver in the attached example.

    If I ever to a redesign, I think I can recover even more pins. In that case, I'll use P16 and P17 to increase the color depth from 6-bit to 8-bit. That will expand the color range past the TV driver...

    I just got one of these, too, in the fluorescent blue color. The build instructions seemed a bit tricky to digest at first, but it looks fantastic when it's put together and it's so nice to finally have a home for the PTP! Thanks a lot Rayman for the PTP and thanks Chuck for the enclosure!

    Cheers,
    Jesse

    Here's a picture of my PTP in its home.

    UniverseRemote.jpg


    There's a second Prop in there to monitor the keypad, encoders, RF link, Wii Nunchuck connector, etc.

    It's main purpose is to control some custom lab equipment but I also use it to control robots and soon TVs and and other IR devices.

    There is room in there for a battery, I just haven't put one in yet. (Probably a two cell LiPo.)

    I know a keypad is redundant on a touchscreen, but hey, I like buttons.

    Sorry about the picture quality. If I used a flash, it washed out the screen.

    Duane, looks neat, thanks for sharing the photo!

    I'd also like to do a touchscreen remote control someday...

    Yes, very. See my website for more info. I've also started shipping the "PTP shield" to GadgetGangster.com to sell...
