Raspberry Pi are already evolving

The Raspberry Pi is evolving right before our eyes

Boosting the USB currents:
http://www.raspberrypi.org/phpBB3/viewt ... =63&t=8591

Replacing the USB connector:
http://www.raspberrypi.org/phpBB3/viewt ... =29&t=8686

Somone else desoldered the ethernet and replaced it with a pin header.

Overclocking:
http://www.raspberrypi.org/phpBB3/viewt ... =29&t=6201

USB HDD's, wireless, playing the xylophone. Flashing lights and reacting to real world inputs.

What will we see tomorrow!

Not to mention lapdock portability mode (and batteries are included :) ) support for the larger, faster SD cards, OpenGL ES support in Python (plus Pi3D under development), displaying OpenGL ES images within an X window, etc.

I'm poking along getting OpenGL ES based 3-D model primitives ported to make it possible to display, manipulate, and combine them for use in Panda3D (if the port of that will fit in RAM - which is still under evaluation and potential development). These primitives are needed whether Panda3D will fit within RAM, or not, and are fun to play with, if nothing else, until more sophisticated 3-D tools are ported or developed (I'm beginning to realize it's probably going to be more of the latter than the former due to the RAM limitations).

The future's so bright, we gotta wear shades! 8-)

I have removed the composite video, audio, and ethernet connectors from mine and boosted the USB currents with the pi-pass jumper. I'm also planning to replace the USB connector.

I'm trying to figure a way to use a micro SD card that won't stick out the side of the board. I'm considering replacing the SD socket with this: http://www.sparkfun.com/products/544, or possibly adding it on top of the existing socket.

Thanks @AndrewS: I had not seen that one. He flogged that RasPi pretty hard :twisted: It almost doesn't look like a RasPi. Now if Gert would lash up a switching regulator board as a daughter board for us. :lol: He did say months ago he "might" do it. Of course he is pretty busy with his real job, his other job (RasPi) and the Gert Board. Whats one more job! Huh! :lol:

I almost reported that post to the NSPCRP* :shock:

That's pi abuse if I ever saw it.

As long as it works how I need it to work... :twisted:
This is the whole point of this, right?

Actually, these projects remind me of this Monty Python sketch http://www.montypython.net/scripts/terrier.php :?

Tell it to the Pi cops :lol:

Whatever floats your boat - just as long as no Pis got hurt. :cry:

I can't imagine that having all your connectors desoldered is an entirely pain-free process :twisted:

Your Pi has had a breast reduction, face lift, liposuction, lung transplant and who knows what else. Now if you would just take more pictures and type a little more! Especially the linear to switching swap. And the Lapdock switch from micro the HDMI A.

You really have been busy with that RasPi. When are you going to change out the memory module for 512? :shock: :lol:

its been said before taking a cold chisel to the 256Mb POP or was it BOB assemble to separate the memory from Processor isn't an option unless your very careful :lol:

At this point I will not put anything past @godFather89. Replacing the memory module is not impossible just impractical. Remove memory, reball the SoC because it will probably come off too. Replace memory module,after solder balling it, then replace SoC onto PCB. Of course the heat will damage the 25MHz crystal so then you will have to replace it. Half of the other components will probably partially or completely desolder so you will have to fix them. It has been discussed in depth on multiple occasions. I still do not put it past him to at least try at this point. He dove right into swapping the micro HDMI for a full HDMI connector. That is a pretty tiny bundle when you consider he says there are 18 wires in the micro, 19 wires for the full size. I have looked into that Lapdock connector area, not a lot of room in there. I assume he remove the full harness from the Lapdock first.

I think you are confusing me with someone else who did the HDMI swap. All I have done so far is to remove some unused connectors and add the jumper to increase USB power. I do intend to replace the USB connector and possibly the SD card connector. I won't try changing chips, though. Too many teeny leads and I don't have a reason to want to do it anyway.

Sorry jbuehl your right that was @godFather89. So I guess I do not put anything past him. :oops: :lol: :lol:

And here are some guidelines for modifying the lapdock:

Will post more soon.
Unfortunately there are no pics from inside the plastic. Will take some next time I tare it apart.

About changing the memory, no chance. I don't have the tools/experience to do it.

@ godFather89: No I do not think there are very many people that could accomplish it successfully. And thank you for the link and pics.
