With the recent announcements, I have taken a spare TouchPad apart to do some hardware modding. I plan on piggy backing one of the 10 cheap SD readers that I purchased from DealExtreme to the TouchPad's SIM slot, internally. At the moment, I'm also looking for alternative methods of internal power for USB Host Mode, as well as a reliable source of 5v power for the SD card reader.
While I'm in here, I might as well look for a solution to remove the creeks that plague the "cold" screen TouchPads, most notably the one at the center of the rear, so I will do this as well. If successful this will render the use of a Y-power adapter moot for those who use USB devices. Will either lead to anything? I can't promise, but my multimeter and I are hopeful. Stay tuned!
