Pick and place remote controlled robot

This is my latest venture. This is a pick and place, remote controlled robot. It took me around six hours to build this from Tamiya DIY kit and another two hours to make it work properly.


Its grip is good as it can hold both a table tennis sized ball and a kick ball.
But the gear boxes have some teething problems which is why some times it refuses to move ahead[as seen on video ;) ].

I wish to roll out a Line follower soon after this, but as I'm facing few blockades which is why I'm unable to do so.
Hope it rolls out soon.

Do put in your comments.

Hello ARM COREs!

Posted by Picasa

This is my first venture on ARM cores. After trying a bit, I succeded programming the CORE on an LM3s811 evaluation kit.
This wasn't that hard compared to programming the Atmega core(see this to know how I struggled/struggling to program the MCU).
The text you see is on a 96x16 OLED screen. The chip you see on the left is the LM3s811 MCU. And its fun to program the core on Keil!

Ubuntu 8.10 reviewed


The new Desktop effect on Compiz and a KDE 4.1 Desktop sporting new look.

This weekend (1st Nov) I upgraded to Ubuntu 8.10, which took a staggering 10 hours to update my box which hosts both KDE and Gnome. So I thought to review Ubuntu as a simple end user. Here it is

Firstly the things I liked:
  • Amazingly fast boot/shutdown time
  • KDE 4.1
  • Good looking art work for both KDE/Gnome
  • Slightly new Compiz effects
Then comes the things which make Ubuntu 'Rocking' always:
  • Superb driver support
  • Easy up-gradation/installation feature
  • Quick fresh install feature
  • Vast repositories
  • Amazing media rendering/acceleration with Amarok
In the end some things which makes any Ubuntu user 'Irksome'/'Pissed off'!
  • Kaffeine is gone for now.I dont know why KDE ditched Kaffeine and replaced it with some 'Dragon player'.
  • Hell long updating time! It took around 10 hours for me to update. I've seen even Vista taking such humongous time to update but I like Ubuntu and I want to it to make me feel 'GOOD' ;)
  • Initial glitches with sound I face every time I upgrade to new release.
  • Dirty looking GTK apps on KDE.
  • A difficult to remember keyboard layout for Kannada( in general Unicode).

Psycho-Reviewed:Watch it at Thy risk!

The must awaited Psycho which had raised to fame through Raghu Dixit's music,is finally out. The story revolves around a Psychopath,schizophrenic person who loves a lady in his Rehab period.

Warning: Spoilers about to help you!

The story starts with the hero running like Tom Hanks in 'Forest Gump' all around with background music something similar to Ramstein's , while he tries to net his lady love. When she's about to fall for him she gets to know he's a Psychopath,schizophrenic person, which makes her crazy. When Psycho gets to know this, all his rehab goes in the gutter and dies. Seeing this the lady love also becomes a Psycho!(sheesh!)

The casting did not deserve all the hype generated by the team to keep it a secret till the end. Film has lots of loose ends, narration is worse.
And also watch out for the nerve wracking yelling of "paaavaanaa" all through .
The only credit to the team is for the camera work and Raghu's amazing Music.
In the end it isnt worth a try in the theaters. I suggest any one who wants to watch this movie to just buy a copy of the audio and settle for it.

My rating for the movie is a Two on Five- 2/5
