I just picked up a different screen for it so progress should be starting up again soon. I think the lowest it can run at 8v so hopefully that's not a problem.

Ah great to hear! Looking forward to your new progress!

What screen did you buy? Did it cost much? (I'm really having a difficult time finding a big enough screen for a fair price)

Oh yeah this thing. I wanted to have this done by MGC11, wasn't even close, so here I'm trying for completion by MGC12, probably won't make it by then either. :p
Anyway here's a bunch of stuff that happened to it a while ago that I neglected to post.


I painted it for some reason, even though I wasn't really completely done with cutting the case. The color is called "Pebble" it's a decent tannish-gray to try and give it a retro aged/faded gray plastic feel, which I doubt it does but I kind of like it anyway.


Pesky rf box just wouldn't come off with desoldering tools so here's Ben dremeling it off for me at MGC 11. We sure put him to work, with this and some desoldering he did for Lorne. Guess I owe him a beer.

Anyway what stalled work on this was that I was having trouble with the PSone screen and getting a picture. It just kept showing a blank screen with the backlight on so I just decided to find a different screen before I broke it, since I do still use it for it's intended purpose. Production on this stopped until a few months ago I found this Intec Screen at Goodwill for $2.



It's kind of crappy but this is just NES so the screen works decent enough for that.


The backlight on this thing is HUGE. Even so, I'm not going to LED mod it, at least not for the time being. It fits fine with the LCD in it's part of the case, and this isn't necessarily a portable so I don't need to worry about battery life.


This screen is also a bit bigger then the PSone screen, so I had to recut the screen hole. I'm going to use the screen cover overlay that was on the Intec screen to begin with, since I really didn't like the look of the thickness of the bezel with nothing there. Gotta sand it down and repaint but it came out good enough. I was worried that I would overcut it and it would keep falling out and have a noticeable gap when I secure it in.

...and that brings us up to date. Didn't tinker with it much during the summer but I'm back into working on it slowly. Tomorrow I'm going to relocate a few capacitors on the bottom of the board so it will sit lower in my case.

Nice work dude! Keep it going

Keep it up man! Can't wait to see it finished!

Just amazing....

Hadn't touched this since the last post. I Brought it to MGC2012 to do some work on it there but never really got around to it with Nomad mods and all the show happenings. Today I finally got around to getting the everything to run off of the same AC Adapter (remember, not a portable so no need for batteries). I'm running everything off of the Screen's Power Adapter, and it works for about a minute or two before the screen goes crazy, and then the audio freezes up a few moments later. The screen has both a 7808 and a 7805, and for the power to the NES I wired the +5v from the screens 7805 directly into the NES so I suspect it's overheating. I'll try to either heatsink the screens 7805 to something better (right now, attached to the screen it has nothing), or wire an additional 7805 directly from the 7808 instead. The latter is probably overkill and completely inefficient but again, it's not a portable so I don't need to worry about battery consumption.


Everything haphazardly wired together and working off of one AC Adapter. Since this is a laptop and will essentially be in two parts, some wires will be visible from the outside of the case. I'm going to use the cable from the NES for the wires between the screen and the NES to keep it looking tidy.


Then after a few minutes this happens. Pretty sure it's overheating, as the time it takes for the screen to wonk out varies. I got halfway through Toad Man's stage on the most recent test, and then of course it flaked out in progressively less amount of time on each reset.

Holy cow progress!!

If the screen fizzles out after a minute, it might be because the power supply isn't providing enough amperage for the whole shabang. The NES sucks up a beefy 650 mAh by itself. Dunno what the screen itself pulls, but i'm sure it's taking a bit since it's rocking a cathode filament for a back light.

Looking good. XD

I just wired up a separate 7805 through the +8v out of the screens 7808 and it works fine now, but of course more peril as the screen is too think and doesn't fit in the top of the case like I apparently thought it did when I posted such (not sure what I was thinking there). I'm undecided on what to do now, whether it be to remove the backlight and LED mod the screen so it will be less thick, or just get one of these 5" car monitors. The auction mentions that it's 4:3, but you know how that goes with Chinese Screen Auctions, even if it would make more sense for them to say it was 16:9 when it isn't instead of the other way around.

Anyway, since no actual progress has been achieved, here's a picture of gratuitous Game Genie daisy chaining on the project instead.

So many Genies!!!

Looking great so far!

Bump.

Still working on this project, been though a lot of revisions. I the Ps2 screen that I was trying to use would not play nice with an LED mod (some ground spots the lights were not nearly bright enough and the picture was way too dim and murky, and other spots the backlight completely washed out the screen), so I'm back to using a PSOne screen. Here's a picture of everything haphazardly wired together for testing purposes.



Everything will run off of the PSOne adapter, and a switch will be put in to change to AV output to a TV/additional screen. A lot of this thread is me just spinning my wheels so I'm going to clean up the first post and any additional posts of mine that are now irrelevant to the project.
