My first obstacle avoiding bot based on the tutorial by Community of robots. This is my first one and helped me learn a bit about sensors, feedback and servo operations. One difference in mine is the use of IR proximity sensor which I had lying around instead of the Sharp distance sensor. This one does not measure...

I was fascinated by LASERs when I first went to IIT Kanpur during my school days. Since then I have been reading / playing a lot with LASERs. My first one was a LASER trip wire and then a LASER pattern generator. It all was around 10 years back. Having recently acquired an Arduino UNO a plethora of options have opened up. I have started to learn from the beginning and this time I have the power of a...

Arduino – 7 segment Dice

January 23, 2012

I have been waiting to play with embedded programming since and recently ordered an Arduino. I tested the spare LCD and displays with the normal tutorial commands and went step by step remeber the thing about slow and steady! I want to build a vector LASER projector and a quadrocopter someday but that is too far. It is kind of my VISION. My Mission is to learn embedded programming via arduino. It is one hell of a kit. My very first experiment was a 7 segment dice.

Why investors are not making returns in the stock market

January 4, 2012

In the last 10 years, sensex gas grown at 17.79% CAGR. That means, if someone could have invested Rs. 1 lac 10 years back, it could have grown to 5.14 lacs. In the last 10 years one third of diversified equity mutual funds have delivered a CAGR of more than 25%. That means if someone could have invested 10 years back in these mutual funds Rs.1lac, it could have grown to Rs.9.31 Lacs. But how many investors have REALLY got these kinds of returns…? In this context knowing about the...

Dock for Xps m1210

This is a docking station made by me for my DELL XPS m1210. I was having trouble as the Laptop became very hot when placed on the table as it jam packed from inside and the temperatures of the insides soar upto 94 degrees (celcius) and mind you thats too hot to even touch.

So i made this dock with a usb fan ( normal cabinet fan with usb cable attached ) and a laoding slot for my portabe seagate 80 GB Hard Disk.

The dock is made of scrap and some glue.

For cooling I tested it with a smoking stick and thus proper placement was decided for fan and the air vents. you can see in the vdo that the smoke is sucked into the vent very well when the smoking stick is brought close to the vent. This is a cool and easy method to check air flow for the desktop too.

Now i can play Supreme commander wihout my computer getting slow due to increasing temperature.

For temperature monitoring I used I8kfangui It works great for Dell notebooks.

The dock is made of styrofoam that was used as packaging for my 5.1 Speakers Umax Powerbeats.I kept the packaging just in case I might make use of it someday. What can be a better use than this.

I don’t know If I said it already but …Excellent site, keep up the good work. I read a lot of blogs on a daily basis and for the most part, people lack substance but, I just wanted to make a quick comment to say I’m glad I found your blog. Thanks,

A definite great read..Tony Brown

Hi,
I’ve got an m1210 also, and like you, I have been experimenting with various versions of OSX86. Right now, I’m running 10.6.4 (Apple retail version via EmpireEFI 1063 R2 boot).

My m1210 has run excessively hot at times in the past, but I found a way to solve the problem without resorting to a dock like yours, or a laptop cooling pad. When I took the machine apart to install 3 wifi antenna jacks, I found that the inboard side (intake) of the heatsink that’s under the left side of the keyboard was completely coated with dust so that it looked as if it had a gray felt air filter stuck onto it. I cleaned out the dust and then removed the heatsinks and replaced the thermal compound with that diamond compound (I used the 7-carat tube). Upon reassembly and powering up the laptop, I found that it ran quite noticeably cooler – and I’ve since made this filter cleaning exercise an annual event for the machine.

I must comment that I find your blog both interesting and informative and it I think that you consistently demonstrate a considerable aptitude for computer technology along with the ability to find clever and often unique solutions to problems.

Thanks for the effort.
