DukePad (Build a tablet with a RPi)
- Osmium 13y agoThat calculator icon looks suspiciously like it could be a rip-off of the iOS 7 calculator icon. That said, looks like a wonderful project. I'm always struggling with the best way to access a headless Raspberry Pi. If something like this were a little cheaper it'd be great. The tablet + ethernet port combo is a great idea... Are there any Android tablets that take high speed ethernet port adapters, making them suitable as servers?
- ClashTheBunny 13y agoMy Viewsonic G-Tablet has a 10/100 ethernet port in the dock. It also has space for a miniPCI card if you want to solder something extra on. Either way, it can saturate my crappy internet connection.
- atmosx 13y agoIt's still 367,55 USD and it's too much... Maybe in a couple of years all these technologies will cost less for us to make something useful out of it.
- timthorn 13y agoToo much for what? If you want a top spec tablet, this isn't the project for you - this is about building something yourself, and to be able to do that at under $400 is something that was unimaginable a few years back.
- a3n 13y agoYeah, exactly, and you've got the flexibility to build something somewhat different than what's presented, depending on your needs or interest.
- djhworld 13y agoHow performant is Java on the RPi? I'd like to see some videos of the DukePad in action
- wiradikusuma 13y agoif I'm not mistaken, you need to pay for license to use Java embedded commercially?
- ChikkaChiChi 13y agoThis is DIY, not commercial use. It's just the plans.
- smoyer 13y agoToday you do, but Java9 will expand the idea of the modular JRE and allow you to tailor what's included. They were pretty clear that the road forward would see JavaSE and JavaME merge into a single project with different "profiles".
- a3n 13y agoIs Java, or JavaFX "essential" to an operational tablet, or can this table just run the default Raspbian LXDE?
- ChikkaChiChi 13y agoJava is specific only to the interface. A cursory glance at the parts list shows nothing that wouldn't work on a Raspberry Pi in any other form factor.
- smoyer 13y agoI was at the JavaOne Technical Keynote for the demonstration and they've specifically optimized the Raspberry Pi to use the GPU for rendering the 3D graphics. Since a tablet is graphics intensive, this is why such a low-end processor seemed so performant ... it just doesn't take that much processor to handle touch events and tell the GPU what to draw or animate. P.S. Project Sumatra was announced at last year's JavaOne and allows Java to run parallelizable code on GPUs. (https://wiki.openjdk.java.net/display/Sumatra/Main https://wiki.openjdk.java.net/display/Sumatra/Main) P.P.S. The coolest interface to their chess server was a chess-playing robot, also built around a Raspberry Pi and using standard hobby servos. I believe that project will also be open-sourced.

- ChikkaChiChi 13y agoAll I want for December Holiday Celebration Day is a touchscreen that interfaces to HDMI directly without the need for an external daughterboard.
- chromaton 13y agoI'd suggest using polycarbonate for the case instead of acrylic.
