Smart! I wouldn't have thought of that! I am wondering, it sounds like the display has the same pinout as the Portable, so would a adapter for the Portable work on the Powerbook?

This is so cool! I can't wait to see more! Why did you decide to start with the display first?

Do these HDMI traces look like they are run good? I think they will be okay. The Maximum length difference between traces is 66mils and it should have 100ohm of differential impedance.

Does anyone have a 3d scanner and has the ability to scan the bezel for the lcd on the portable? Because otherwise the screen is going to be tiny! I am also asking for power consumption reasons.

Alright, the schematic is coming together. I've changed it so many times now!

Great! It'll make the adapter PCB and the controller PCB much smaller too! I just wanted to know if it was a good idea.

Thanks! That would have been awesome to collaborate with him. He seems to have a lot of knowledge about the portable compared to me, but unfortunately I don't have a good way to contact him. On a side note, do you have a good idea on what type of cable I should use to take the odd connector...

No... I just follow his github. If I knew I would tell you. Mine will hopefully be in the same state as his in about a week or 2. If you can wait that long I can give you the pcb gerber and BOM, or if he posts his as finished on GitHub before mine is finished you could probably build it.

https://github.com/rezafouladian/PortableVideoAdapter He's doing it to! If you scroll all the way to the bottom you'll see it.

Hmmmm, Maybe, I am going to finish this one first though. But if I do get a powerbook 2300c I will probably try to help it to! :)

Unfortunately, I know nothing of coding and ran into a little bit of a snag. If anybody could help me that would be heavenly! I have the HDMI plug on the top of the PCB with everything else but the pinout of the lcd doesn't line up with the pinout of the library that comes with the Waveshare...

Look! It all FITS!!!!!! :LOL: Thats that, we'll just print the pcb and viola!... (JOKINGLY TONE) No suriously, that is the max pcb size that can fit in the portable's lcd bezel! Now all I have to do is figure out where and how to route traces...

I am glad someone is excited!

@techknight said over on Tinkerdifferent exact quote: " Tunnelvision. Shes cooked. This is becoming increasingly common. Gonna need to do a screen mod. SuperSVGA published his Pico to HDMI Adapter open-source, and i think its basically the same as what Androda did while his was VGA. "

I would try white lithium grease or sewing machine oil (or machine oil like it).

Now that I have a rough sketch of the pcb I get into the nitty gritty... WAITING for the Waveshare RP2350 PiZero to show up so that I can take measurements. In the meantime, I will be making the schematic for the Waveshare RP2350 PiZero and (crossing my fingers) hoping I can incorporate it into...

NOO DON'T DO IT!!!! :LOL:

Hmm, I guess you're right. I found a trace length difference calculator. The traces can supposedly be off by a little less then 1500mm... Thank you for making me double check!

@SuperSVGA Thank you so much!!!!

Does anyone know why there are grounds and vcc connected to A pins but nothing connected to B pins on the top IC for the A pins? Can I remove one of the grounds to move a D0 to the top IC?
