My new playboard the Olimex Olinuxino A13 dev board running Android 4.0.3

11 Sep

The Olimex board delivers what’s promised an ARM A8 cortex running at 1Ghz with 512MB ram, 4 GB Nand(flash) memory with wifi and VGA connection.

The board is a lot more powerful as the the Raspberry Pi I have lying around, Android is by default installed but you can power it with a linux distro.

I connected it to my LG TV/monitor without problems, you see the Nexus wallpaper running in the background…

The power supply I used is a 6V 1,65 Amps,the same I  used for my Arduino projects. Keyboard and mouse are standard usb devices.

Next step is to 3D print a  box to hold the board, I recently build a Felix 3D printer which uses PLA (corn plastic) to print it’s objects. Probably going to use openscad to make the model. I’ll hope to make the box VESA mountable so I can attach it to the back of a monitor.

When that’s done I can start to make some ‘retro’ games for it and  attach cabinet style joysticks  with usb or using the available GPIO pins. Or make some cool open source games console with it, the board has a lot of possibilities and is very open.

For those  who have a rev B board they can fix the VGA problem with the solution described in the Olimex document here , my LG monitor accepts fine the original signal so I didn’t need the fix.

Oh, I forgot to mention it’s price 55 euro’s excl tax and shipping, that’s for the dev boards, the price will change when the board goes in production. You can still order it online https://www.olimex.com/dev/index.html

Raspberry Pi, 25 Dollar retro gaming platform ?

4 Sep

Just yesterday a blogged about the Gameduino a low cost 8-bit gaming platform, today I came about the blogpost that R-PI (Raspberry PI) can run Quake 3D on TV composite output or HDMI screen.

That’s amazing what you can do with such a little footprint computer. The R-PI is based on an Broadcom ARM with GPU acceleration, powered at 600 Mhz, 256 MB Ram and usb ports for mouse/keyboard and external memory.

This is a little beast with an awesome price just 25 us $, the platform is developed for educational purposes and for the developing countries. But what way to start programming better than by programming games ?

Hope to get my hands on one of the early devices soon in the near future, production is planned for late 2011.

Some nintendo 64 style 3D games should be possible on this machine, hope they enable WEBGL in the browser that way you could start programming with just javascript and webgl using a library like three.js, the future looks promising !
