How are you guys doing all these visuals? I've poked around and found some decent software, but it all costs like $200+. Is there a hardware solution to mixing video feeds? I've got enough random video gear, but no way to mix it...

i can host it somewhere else, sure, but i'm curious why you guys dislike mediafire?

It tries to open up like 6 popups every time I visit the site, and the sliding ads just get annoying.

This, seriously. Get a box.net and you get 1GB of no hassle upload space.

Re: LSDJ Keytar (4 replies, posted in Nintendo Handhelds)

Whoo, thanks for the help arfink! That answers pretty much all of my questions. I think I'll just hit up one of the EE Majors to help me figure out how the pot connections work.

If it works, I will be so ridiculously happy.

@TraceKaiser
The problem is that if you look at the board, the Start and Select buttons are covered by the case, and the bottom of the D-Pad just clips the case as well. Larger Picture
So in the interest of looking nice and uniform, I'm going to try and cover the entire area around the screen, and then just wire the keyboard buttons to the contacts on the DMG PCB. Although, now that I think about it, there might be a better way to do this, like putting the A and B buttons on the side, Start and Select through the case at the position they are now, and then mapping the D-Pad to the arrow keys like planned before. Hmmm, I'll have to play around with it I suppose. This entire project was just started on a whim really so it's just one grand experiment. ^_^

I guess the biggest issue is just figuring out how to place everything inside the case. I have significantly less room than expected, but still enough to barely squeeze everything in. On to rewiring everything ever and hoping for the best!

Topic: LSDJ Keytar (4 replies, posted in Nintendo Handhelds)

So I've successfully made an LSDJ keyboard. But I want to be able to play the thing without having to deal with clipping a DMG to my belt and potentially entagling myself in wires. Solution? Put the DMG innards in the keyboard casing and make it a Keytar!

(This isn't wired yet. I just cut out the Numpad and placed the screen PCB inside to see how it looked...)

So this is pretty much the first electronics project I've ever done, so I've got a few questions about wiring and all. If anyone has any tips at all, it would be greatly appreciated. First of all, I am going to have to wire a new volume pot so that I can access it through the keyboard casing. However, I am horrible at deciphering the DMG Circuit Schematics. So I think I've figured out that I will need a 1K ohm stereo pot to replace the current dial thingy, but I'm not sure where to solder what on the PCB. If anyone has help for this it would be great. (PCB/Volume Pot Picture) I will have to do the same with the contrast dial, but as it only has 3 connections, it should be easier to figure it out on my own. (Although I gladly welcome any knowledge you have.)

Also, can I remove the cartridge reader component and place it somewhere else in my casing with ribbon wire to the PCB? Is this even a good idea? This is critical, because if I can't do this, I won't have any room for that back PCB due to it's thickness.

And now for the less detailed questions:

How can I wire buttons on the keyboard to the contacts for the DMG buttons? Is it as simple as carefully scraping away the top layer and soldering? Or is there something else I need to do?

If I remove the DMG speaker, will it affect any of the circuitry in a way that should concern me?

Can I just wire the all the ground connections on the DMG to the ground plate on the keyboard?

Does soldering two or three prosound mods to the PCB affect the sound quality or limit the DMG's ability to even run? I would like to have 3.5mm stereo female out, 1/4" mono female out (stereo to mono conversion done internally), and if I have room, RCA females out.

Whoo, that's a lot I don't know. I also might try underclocking it for good measure since it is supposed to be a performance instrument. I'll probably have questions about that as well later. Apologies for my lack of knowledge, but I'd appreciate any help you guys could offer.
