canon camera teardown, a set on Flickr. A couple weeks ago, at work I found a digital camera that was thrown away in the recycle bin, it had a broken LCD and everything else seems to be in good shape. It was a 2.1 Megapixel Shooter so i figured it must really old. On googling I found that it was launched in 2001 and one of the smallest digital cameras of its time. and cost like $600 US! these days you can get a decent DSLR for that price. Check out the review of this device here! ...

I have a Dual Boot boot system Running Ubuntu 12.04(LTS) and Windows & Home Premium(x64). The other day i was booted into ubuntu and had to use gparted to partition and format a flash drive to use with my Pogoplug-B01. And i by-mistake formatted the windows boot partition . Oops. I restarted my system and could not boot into windows! For me Windows is like a necessary Evil . Its where all my games reside! All for the other programming related stuff i use ubuntu. So i needed to get the windows partition up and running. ...

I just started playing around with the TI Stellaris Launchpad a couple of days ago. The Launchpad is a pretty powerful little dev board. It has ARM Cortex-M4F core at it heart. The really awesome thing is that there’s a Full fledged debugger built-in which makes it a really good board to start with ARM micros. I was fiddling with the UART trying to setup two way communication with the micro. so i started out with the uart_echo project included in the Stellarisware bundle. ...

A couple of days ago i received in my order of Philips SHH7810 in-ear headset from Flipkart.com. They delivered it in like 2 days as promised. I love their service and sometimes the price is also very reasonable as compare to brick-and-mortar stores,which was true in this case.I got it for 985 INR,which i think was pretty reasonable. The SHH7810 in my opinion is one of the cheapest and quality headsets with inline microphone that money can buy,I had done some research prior to finalizing this one, i coudn’t find any decent brand(aka sennheiser,skullcandy,sony,etc) earphones with inline mic and call.answer button,there was one from skullcandy around the 1k INR range but i was using the skullcandy ink’d for the past 8 months which was very similiar,I wanted some change and this had to be it. ...

Motorola launched the atrix 2 in india late last month. Almost six months after they launched it in the US. It seemed like a good vfm phone given the market price of around 22,000 INR and the many positive reviews all around the internet made it seem like an awesome buy!!! So i thought i should check it out.I ordered it,from probably india’s answer to amazon flipkart. it arrived 3 days post order. Packed snuggly in couple of layers of bubble wrap which i enjoyed popping! :P. ...

Just Completed the Build. Check it out! Soldered the FT2232 using the drag soldering method.Had to remove some stubborn solder bridges formed during the soldering of the fine pitch QFP using a razor blade! Thanks Ian and Dangerous Prototypes! 🙂 ...

RGB LED strips such as this are available for a low price.They are generally bundled with a IR controller and a power supply to power the LEDs and to change the color ,display various colour sequences etc.The IR Receiver is similiar to those used in TV and requires line-of-sight for reliable operation . I wanted the strip to be Controllable via a PC or a Mobile Phone.So I decided to make my own RGB LED strip Controller and to enable wireless control i used Bluetooth technology.The device can be controlled using a PC or a mobile phone with Bluetooth having a suitable graphical user interface. ...

Just a Simple code snippet that allows you to send a byte over a 8-bit wide parallel bus when using 32 bit devices such as those based on the ARM architecture. While programming AVRs this usually would suffice to send a BYTE over a parallel 8-bit wide port.Here’s an avr-gcc example PORTC = data; But with the a 32-bit microcontroller For example the LPC1768 from NXP. Each port is 32 bits wide and in order to send a byte over an 8-bit section of the 32 bit wide ports ...
