If you’re looking to build a really big Android tablet the trick is not to start from scratch. [Peter] pulled off a 23″ Android Tablet (http://beyondthekeeboard.wordpress.com/2011/10/05/bigscreen-android-with-touch/) hack using a collection of easily acquired parts, leaving the hard work up to hardware that was designed to do it.
He didn’t really build a tablet, as much as he built a big touch-screen add-on for one. He already had a couple of inexpensive tablets on hand to play around with. One of them has an HDMI out port, which let him easily push the display onto a 23″ monitor. He knew the tablet was a 4-wire resistive touchscreen, but he didn’t know if other touchscreens with the same number of connectors and be directly swapped and still work. To test this, he cracked open a second tablet device and connected its touchscreen to the first one’s hardware. When he was met with success it was time to source a couple of 23″ touchscreen overlays to test with the external monitor. As you can see in the clip after the break, it works like a charm!
[Peter] was inspired to write about his experiences after seeing the 23″ Android tablet video in our recent links post (http://hackaday.com/2011/10/04/hackaday-links-october-4-2011/).
