Well in my time home from college I have made a Sega Dreamcast tablet. It has a 14.8v 6600mah li-ion battery in it. The GD-Rom has been converted to a tray loading drive that I call the GD-Drive. The screen is a 15" screen.

If you want to see some making of pictures and some info such as the schematic I used to control the GD-Drive as well as a GD-Rom pin out for the controller board relocation just in case you tear a trace check out my work log found at...

Now for the pictures. (Sorry about not being able to see the screen very well. I couldn't get it to show up very well.

Nice!!!

Awesome job dude.

Epic. That's some impressive stuff there; well done!!!

That thing is awsome!!!!!!!!!!!!!!

That is pretty freaking cool. I'm loving it!

that thing is beast! and you got it done for the 9/9/2009

Sweeeeeet!

Thanks for the comments! I am planning on taping another video of purely game play in a typical playing environment. I went and got a bunch of Dreamcast games for $3 a piece including power stone, sonic adventure, the full house of the dead 2, as well as hydro thunder and a couple other ones. Also I plan on putting my findings for the GD-Rom pin out in the Dreamcast section and I also will post the schematic for my GD-Drive on here when I get around to it. Thanks for checking it out!

That is AWESOME! It's unique and well done!

Thats pretty sweet. Its not really a "tablet" though. As tablets are touch sensitive. But Im loving the design.

awesome job, looks really sharp but PLEASE get some better pictures, your current ones are awfully dark and it makes it hard to tell what exactly is going on
tablet just refers to the formfactor of the design, the fact that most tablet computers have touchscreens is irrelevant

Yeah I had a difficult time trying to photograph it. Every time I took a picture with the flash off everything would come out very dark no matter what the lighting conditions were. When I would take a picture with the flash on it would wash everything out. The video came out well though so I'm pleased about that. But I have access to a SLR camera so I will try that out and see if I can get some better pictures.

This is great! I think this design is very unique!

Excellent work! Very sleek looking! What kind of battery life do you get on that?

Well I wish I could tell you.  I haven't actually been able to sit down long enough to play it coninuously until it died.  But I can tell you that on a full charge it ran the whole time that it was used to make my youtube video, which was about an hour and a half of "ON" time cause I could never get the part where I was speaking to sound right.  It also was on while I took pictures of it which equates to probably 20 to 30 minutes of "ON" time.  Then today I played it for two hours.  Then plugged it into my tv to play a game for a about 30 to 45 minutes.  So during that time the sound was all the way down and the screen was off.  So If I were to guess I would say anywhere between 3-4 hours, probably no more than that.  But thats just a rough guess and those "ON"/play times are bound to be off.  I just got a bunch of new games so after I charge it back up I will try to get a continues play time for it.
