Friend of mine found full sized GameCube case replacements which should make installing a board dirt easy. I know of a supplier that has quite a few remaning but I can't afford to snap up $400 worth of merchandise that might remain unsold for some time. Cest la vie.
I recognize that pink bird...

you should join us on IRC to discuss a bit further...

welcome aboard mister ;)
we should talk about those replacement cases! you're not talking about divineo.es are you?

By the way. How is the digital audio board going? Also you plan on making more of the mx chip version only? Or is the rest now going to be together on 1 board?

I use it everywhere. :D

I'll go ahead and start idling since you don't seem to be in #gc-forever right now.

They're the only ones I know of who still have any. Last time I tried to place an order the shipping calculator maxed out at 50 Euros after X number of cases. Other people I know who have ordered from them pay and then later receive an e-mail stating that they need to cough up a bit more to cover the rest of the shipping costs. If you buy 30+ cases the cost per case begins to come down but that unknown variable of shipping may rear its ugly head.

Sometimes being in the US sucks.

all future video boards will be all in one with audio...
only you and ashen got special order video boards...
also, ill make your board tomorrow..

shipping to germany wasn't better either....i actually thought about driving there and picking them up myself, would be cheaper i bet :D

My mom is in Spain now, so I hope the cases arrives in time there. Unfortunately it is a bus trip so she can't take more with her. If they still are in stock next summer vacation when we go to Spain, will take a load with me (if there is still interest then) :lol:.

I know you're using the UV transfer method to make these boards. Have you ever tried heat transfer like this:

I'm looking into getting into PCB making and was curious as to which way is better.

that tube is pretty straight forward...
i used heat transfer for years...

there is a lot of that is not mentioned in that video using this method...
maybe best for the subject of a new thread....

here is the fiber optic board..
this will be the stand alone board for anyone who wants to add internal fiber optic audio only..(no video)


im my opinion, it may be easier to add this board to the GC with only 5wire connections to the mobo rather than disassemble the component video cable...
i have disassembled 3 component cables already and the metal shielding must be bent to remove and access the video board.
then 5wires must be connected to the video board...on top of this, the tricky part is to bend the metal shielding back into the original shape (or close enough to original shape) in order to properly close the plastic housing...
although this may or may not be a simple task, i dont have the patients to mess with the shielding long enough...
i dont have pics of the metal shielding readily available but im sure you all know what im referring to...

anyone who wishes to add external fiber optic audio to the component cable will have a slightly different board design with just a few more components, and must also mod the component cable housing to allow the wires to pass thru from the video board to the audio board..
at the same time, the GC housing must be modified for the internal board to add the FO connector...
i would think it may be easier for most to mod the GC case itself disassemble the component cable shielding and reassemble and then mod the component cable housing..
note = when i say easier, thats because im lazy



some notes about the internal audio only board:
the internal design uses stacked components to save board space and make the design as small as possible...
i needed to minimize the footprint of the audio board to allow me to use it on the video board also...
...so this design is used for both internal audio boards only and full audio/video boards too...(with small differences in circuit pathways, but same footprint)

here is the lower layer of components..
74HC04 hex inverter
3 capacitors
12.2880 crystal
0 ohm jumper
and 2 jumper wires

Image



...and here is finished product
TC9231N
47uF capacitor
and super glue on the jumper wires just in case

however at the same time, you state your monitor is incapable of receiving 15khz signal yet you can view everything normal with no issues...

one possible explanation that comes to mind while viewing different images on the web:
there appear to be different revisions of the chip or (most likely) different production run ID's.
it would be nice to confirm if the last line is indeed a rev change (wishful thinking)

if you can still get access to your chip, please post the chip Rev/ID (or a pic if not shown below..)

Code: Select all

B012355
CMPV-DOL
T2164(xxx)
I have confirmed 4 different Rev/ID markings so far..only three shown below.

Resurrecting this from page 7 of this thread. I recently opened up the Revolution to do a few things and took pics of the component chip inside.

It seems to me that the chip is a later revision? and may possibly correct the 15khz signal issue by displaying everything in 31khz VGA mode interlaced or not? Its the only explanation I can come up with unless the Dalian "good screen" suppliers are lying about the capability of their screens, which I can't see why they would.

whoa!!!!!
39k3
damn!!!



thats the first ive seen...
wow....
looks like i may have my chip markings a bit off by one digit...
and also...your chip may be the earliest documented production run....


the more i think about it and the more ive learned...i imagine all these chips are the same...
no internal changes...
if your up to the challenge....i guess one way to determine this is to take the chip i sent you and wire it up to prove the possibility of chips ability or monitors ability...
which chip version did i sent you?

im thinking Dalian Good Display Co., are indeed liars...
liars because they have to lie...
they may not be able to specify their screens are able to display 15khz...i still think this goes back to my theory of a contractual agreement...


good job and lucky you for possibly finding the earliest documented production run version

Of course, in every way! Really looks professional and the signature is pure art. It's a shame it has to be put away the Gamecube, not in sight.

pr0ton,
ill need to create a method for adding pins to the board so they are in perfect alignment to slide into the digiport holes...
i thought it would be a lot easier to add the pins but i guess not...well yea, its easy..but i want the pins to have "perfect" alignment...
i ordered some materials which could help in making a connector type thing to keep the pins in aligned...
...currently awaiting for delivery...(next week)

iggunr,
while im waiting for the stuff to arrive for the connector, ill start working on your board...
stay tuned...i should have the board finished this weekend...


Zen,
im a slacker...your package is going out tomorrow...

i just noticed i posted a pic of a B012455...
haha oops, i didnt even realize it at the time...


i happen to have an official board with a B012455
since the B012355's ive tested havnt worked with my monitor during 15khz mode, maybe ill have time this weekend to see if my monitor passes or fails during (expected) 15hhz mode with this other chip version...

this should tell us once and for all if the chip functionality was changed or if dalian are liars...
