Those devices aren't made any more. Check ebay if and where someone is selling leftovers. Some still have some unused leftovers from various countries (keyboard layout may vary).

Re: Start an Android App by pressing a button?

You could install a SSH server on Android device and then SSH-in from Raspberry and execute actions of apps you want to run (you have to know/find them), like for chrome browser:

Code: Select all

Re: Plans to support Vulkan?

Usually the hardware also have to support it. You can notice on products specs which version of DirectX or OpenGL given GPU card supports. And on top of that most ARM GPU units supports only OpenGL ES and not the "desktop" OpenGL so it's even farther away from supporting Vulkan.

Raspberry Pi is DEFINITELY more interesting than using a Android phone or tablet and playing games. Though I have used the Eclipse ADK, but the emulator is so slow!

Most scripting is done with Python and not compiled languages like C or C++. You can do cross-platform GUI applica...

Re: Hardkernel ODROID-C1 is a $35 Development Board

Chinese chips sell cheap. On dx.com cheapest S805 is for $59, but simpler stick on aliexpress is priced at $35. RK3288 and S802 are the main SoCs among those dongles so other probably can go cheaper to get rid of surplus.

And $35 may not be the local shop price for end user just like for RPi.

You can use phoronix benchmarks to compare them. You can pick between various synthetic or practical tasks/usage benchmarks.

Raspberry rarely has "idle CPU" :mrgreen: Bicoin mining long ago went to ASIC chips and no CPU or even GPU can compete in any way. Other scientific tasks won't do much on Raspberry either, but you can try if they work - but check if they won't start lagging other tasks the board does.

If you can avoid any C++ code for the backend then it would be very cool (for QML). In general you write once, run anywhere. In my case I just had to freeze into a standalone binary for Windows and OSX (PyQt4) without any code changes. Linux just run the sources without any distro/arch problems.
