Break Out Box Available For Pre-order

I'd modify the Svideo to Scart adaptor, since composite video is nasty...
I need to get and Svideo to Svideo adaptor, so I can use my long Svideo cable that I use for my laptop Tvout. Until then, the TV-out isn't too useful as a feature to me anyhow. The only thing I have used it for is video capture

But, you see, i'm trying to do all this without having to source parts (which can take a while for ICs, I've tried before) so I'll just build whatever I build out of whatever I can find in my parts bin.

EDIT: I could possibly do this, however. I think I have 3 or 4 555 timer ICs.

Source parts? What are you using for the EXT port connector?

I wouldn't trust that circuit for powering USB devices, what is the power capacity? not 1 AMP like this one. The one I showed you is $4.14 at that store, try mouser.com or digikey.com.

I understand if you are playing around, just use a 7.2volt R/C car battery pack and a 7805 like you were going to. For designing it for maximum portability I would use an upconvertor with 2 or 3 cells, the least with the most current capacity the better

To make it painfully easy, go to the second-hand store and pick up a "Car to CD player" style 5v power supply (or check your junk drawer, I know I have at least 2 or 3 in mine ), the circuit will be ready to hook to a 9v battery or a 7.2v R/C car battery pack, I have done that before to power my CD player from a battery in my backpack.

I intend to use one of those data cables from a phone, depending on where I can find one (so yeah, I guess I am sourcing one part). But I am also looking in terms to build it as cheaply as possible, and as simply as possible. Also, as small as possible, which means less cells are better, at least for me. Also, I ask that you remember, I am building this for me, as an experimenter, and have no plans to make them for other people, so I'm not sure why you're so concerned about the way I go about achieving this. If you feel like trying to make a better one, go ahead, I'm sure we could all benefit, but I just want to do this in my own way.

$60?! For THAT?!

Sweet merciful monkeys, whatever it is they're smoking, they need to cut back to a quarter a day.

Might as well roll your own for 1/5 the price, if that. Of course, the problem with that being that the JTAG pinout on the wiki is apparently still wrong.

Oh, wait. This thing doesn't even HAVE JTAG! :rolleyes:



I am... underwhelmed.

I assume you are kidding. You do understand that when you put the capacitor in the Scart adaptor you will be making it function with Composite, right? Because your TV obviously can't accept an S-Video Signal if you are getting a black-and-white picture.

My point was that since your TV doesn't support the S-Video over Scart anyway, maybe it would be more intelligent to make a S-Video to Composite adaptor so that you could use your GP2X on a mate's telly (haha I am from the US, still like to speak English though).

I am just bored and strapped for cash, or I would have another GP2X by now .

The cheapest would be an already made circuit, see my idea of a cig lighter plug in a car, it is usually a 7805 or similar with a Capacitor and a heatsink and will run off a 9volt or a 7.2volt battery pack.

You are under no compulsion to pay any attention to me though, I am just interested in a purely intellectual way in design. I feel like trying to build one, but that does me no good right now because I have no GP2X, I look forward to building one in the future though.

Well, whatever happens in the regard to the Svideo mod... it ain't happening anytime soon... lol.

And no I wasn't kidding... I just assumed that the mod added colour information to the B&W Svideo signal... So you have a nice sharp picture with hacked in colour... that's what I thought.
