I like the break out box idea, but wouldn't be cooler to have a cradle that attaches to the unit? Either as a cradle stand (working on the model for that) or as an attached device on the bottom of the unit?

Looks excellent to me. Maybe we could fit a dpad in there too :)


... Uber geekness would have the thumpad removable , the snap on cradle with a host base that both snap into making it look like a mini terminal... ummm... it can go on...

but the trackball was added, it's ermoveable and you can plug it into the other side of the unit, whichever is more comfortable...

Voila

This is the thumbpad I am going to be butchering for the prototype...

Great idea!
But i think i would need a MK2 then :(


Aren't the previous two versions the same? Just firmware upgrades, the interface port is the same? or is it pin 19 or something like that a little different?? If that's the case, Hmmmm... mayeb a simple dip switch to change the pin config... *runs to wiki...*

That looks bloody fantastic. You should really go ahead with your idea, and then license it to GPH. That would really turn the GP2X into a fully-fledged portable computer. Not to mention how sleek it looks :ph34r:

I thought only the MK2 has power on the EXT port.

Thanks! yeah, I've already started making the housing and started the electronics layout, should be interesting to see how long it takes... this is a weekend project... a few weekends... a whole bunch of few weekends... he ehee... it will be fun to finish though.

Hmm... if we are talking design here, then let me make a suggestion:

Allow it to be able to ACCEPT but not REQUIRE AA batteries. Wifi/external HD would kill the battery life...


Already in the design. Thanks for the suggestion. The unit will add additional source for power (not nessecarily aa batteries) , We will se how everything works once it's put together. R&D is key. Design and layouts always change. This is not the only design I have, there are four others.

Everything will be internal (no hd, you know how large the unit will be if that happened? and how heavy? yikes)
If you want to use wifi, you can plug it in, use a moron power supply, etc. etc. etc.

Again, thansk for your suggestions. There is always a start to everything, the path is always changing to the reach your destination.

Now if you were to sell this, how much do you estimate it would cost(including shipping)?

You know what. I haven't even built it yet, so don't ask me that. Who says I am going to sell it. You going to back the R&D to figure the least expensive way to manufacture this puppy? (Make the prototype, get some quotes from manufacturign facilites, get the die made for the casing, etc. etc. I am not at that point yet)

There will be a few prototyes of different models (with keyboard, without etc.) I am doing this for my own pleasure. If it's feasible to get it mass produced, then great, if not, then ah well. It's a HOBBY. Hobbies are done for fun, Hobbies don't have philanthrapists backing them. Oh and hobbies are done on ones spare time, did I mention for fun? And no financial backers?


Thanks, Cr8tive Leo

Damn, I didn't mean it in offense, what's up with your post? ;) I even asked if you would sell it and asked you to estimate. I don't like it when people get angry for no reason, so just forget I ever posted..... B)

I have to say I agree with Omars.
What are you being so defensive for?
Thank you. :)

It looks cool, have you thought about using 4 AAA batteries? I have been using 4 AAA NiMH 1000mAh batteries straight into my USB devices/hub with a small filtering circuit and it works perfectly.

At 5.28 volts under load it is well within 6% variation and should drop slowly until fully drained at about 4.8 volts, once again well within 6% variation.

Being NiMH they should handle any number of devices without moving parts and likely even would run a 2.5" hard drive, possibly with a capacitor to aid in spin-up.

I bought a super-slim USB 4-port hub made by Sakar at Staples today, they are on close-out and cost about $8.

I used a 4-cell AAA holder with a power switch from Radio Shack to power the USB device/HUB and used a motherboard USB Female cable removed from the bracket for a socket, came out nicely I think :).

I used a prototyping board and some resistors from Radio Shack for the circuit, if I knew how to solder surface mount devices I would use a tiny tiny USB host termination IC under the Samsung e810 shell on the EXT plug
(I was the guy who pioneered the Samsung e810 serial mod on the Forums and Wiki ;)).

So far I have only tested it with moving data back and forth from my brothers Creative MuVo, my Kingston Datatraveler and my other brothers USB SD Reader. I even copied from the USB SD Reader to my Kingston DataTraveler, it takes a bit of time on USB 1.1, but any Divx video file should play back just fine, and the PSX ISO's load in a flash from my Western Digital 80GB external 3.5" drive :).

Edit: Omars, even if you only asked for an estimate you should realize that it is incredibly difficult to give one, I would judge it to be worth well over a $100 easily if you wanted the fair-market value against the GPH BoB and the hand-assembly.

He did snap at you, maybe he had a bad day or something, but he did explain why an estimate wouldn't be possible, you could investigate building a similar device yourself.

I personally want my USB to be across the back at the top next to the SD slot, and fit 2 AAA batteries per side in a "Sega Game Gear" style, I think that would be the best in terms of reliability, of course I couldn't have a keyboard that way ;).
 
It would be fantastic if you succeeded in making this work, and a saleable product.

If you made a reliable plug-and-play gadget, sleek, keyboard functionality, D-pad built in, not too bulky and running off rechargable batteries, I believe a lot of people would pay about £70 for this quite happily, even if it means buying a MK2 to get the functionality.

Please keep us posted with your developments. This I believe, could be the most exciting mod for the GP2x by every stretch of the imagination potentially. Don't forget the D-pad!! :rolleyes:
