Raspberry Pi GUI over SSH

So what after buying R Pi , the much hyped little supercomputer. You bought it with a huge urge for learning phython and develop some cool devices. But then you realise to setup a programming environment u need a keyboard, a mouse, network, a pricey HDMI display. (I swear any RCA  TV or monitor is too low in quality for an programming geek.)        So now your little but brilliant mind start asking why can't i connect and work R pi to my PC/Laptop.   Who can help you... ?????      Praise linux ... thanks to SSH and X window system .... SSH is a protocol , remote login facility for any linux system from another network device. X window is the aplication which runs a GUI in any linux OS. eg:- it runs LXDE on pi and GNOME on Ubuntu . The best thing about X window is that it is forward-able through  SSH protocol... !!  So what is the setup ??? Ingrediants:   1. A linux/ Windows PC ; which is your ...

RCA to VGA using FPGA for Raspberry Pi

Hi all.. Shortly received my Raspberry pi... i took my byte... :) I don't have HDMI capable display or an RCA monitor when i received the device.. But the eagerness was so high to think about an RCA video to VGA conversion, since my PC monitor is VGA capable only and was immediately available with me. I have an Altera DE2-115 FPGA board with Cyclone IV FPGA. It is a future perfect development board with a bunch of multimedia capabilities and large I/O options (still lacking HDMI ).       It have a RCA Video In plug. It also have a VGA output connector. So i thought of connecting Rasp pi RCA output to the DE2-115 board. And VGA out of DE2-115 to my PC monitor. The starter CD with DE2-115 have a TV Box Demonstration program. Refer to the DE2-115 User manual  (page 55). Loaded the .mcs file of  TV Box  program to Cyclone FPGA. Connected and powered Raspberry Pi. Voila... The raspberry fruit logo and boot messages started scrolling up.. and finall...
