Holy macaroni! That's awesome. What kind of DTV did you use? Did you fabricate that case yourself? More information please.

Hey! That's very nice. Seems like it's all made out of wood, and then a layer of tape-like aluminium foil on that?

The DTV is from a Hummer. It doesn't look quite right because I physically sawed off part of the circuit board.... the side with the voltage regulation components That was a fun experience. I followed all the traces on that side of the board and I thought it would work, but I wasn't 100% sure until I did it.
MadModder is correct, The entire thing is made from wood and superglue. The wood is that thin plywood stuff that you get at the hobby store. Then I covered it with faux stainess steel contact paper. With all the cutting and filing and glueing I did, I think it might have been easier just carve it from a big log.
I'm working on a site to document it. I was finally to a point that I could take a few pictures last night and I wanted to post them before someone scooped me.
I'll be publishing the keyboard convertor schematic and PIC code if anyone is interested. Those Jornada foldaway keyboards are really cheap on ebay. The cool thing is that I can have the PIC run "scripts" on power up... like POKE settings and stuff like that. It is also capable of progamming the function keys from BASIC. The PIC watches for a certain "activation" key sequence and then saves the next keystrokes to the PIC's EEPROM until you press another special key sequence to deactivate learning mode. I'm sure you guys are already doing this with custom ROM flashes, but I just about have an anxiety attack every time I start playing around with the ROM and I'd like to keep the flashings to a minimum.

Excellent!, I would have loved to build something like this, but I have neither the tallent, nor the time.

Very, very cool! Love the case (hinges, especially.) It would be great to peek at the PIC code too. You're in a position to answer a question: how much current does the Hummer board draw without the factory power regulator (and the LED integral to that regulator)?

I'll have to get back to you on the current draw since I'll have to take it apart to measure that specifically. Right now I can only back into a number. The whole thing uses 1000 mA (gulp) when running with the LCD screen. I know the screen alone uses about 730 mA. The 3.3v regulator and 7805 are sucking up some current as well since they are warm to the touch. The PIC and keyboard use practically nothing. So the current draw comes out to... ok maybe I can't back into a number. let me just measure it and get back to you.

Wow, this is a work of art. I noticed many similarities between some of my work and yours... It came as no surprise when you said you'd been reading my website. I need to add this to my gallery.
I was surprised to read it was made of wood. It doesn't relly look like wood at all on the outside.

Here are a few pics of my own DTV Hummer project. I had an old PSOne LCD screen lying around and I thought I'd make a C64 laptop. Actually, it's more like a C64 PDA! Brilliant! Simply brilliant! O.K., when do you start mass-hacking these for those of us with no talent? ;-D Happy New Year! Robert Bernardo Fresno Commodore User Group videocam.net.au/fcug

It's beautiful!
I'd be interested in the details of connecting the PDA keyboard. I have a PDA keyboard that I'd like to use with mine, but it's a little above my abilities without someone blazing a trail for me!

That is just amazing. Ive always meant to make an RS232 to PS2 adaptor, but never got bored enough to actualy make it. I cant wait to see the code/schematic you used. Do i detect a 1541-III-DTV space there? The 5pin header and SD slot lurking in a gap about the right size is just too suspicious for me But I have to say, its amazing work. Its just what most C64 enthusiasts have always wanted. Now if you could add a touchscreen and use the mouse driver too, that would make a killer PDA. could we have the model number for the KB? I have an old ericsson chatboard that I beleive also outputs rs232 for the keys, its even smaller than yours.
