if the thing on top is from metal and the rest not a metal detector could do the job.
2  Development / Suggestions for the Arduino Project / Re: Auto Format challenged by long macro with "\" line continuation characters on: September 17, 2014, 01:24:15 pm

the auto formatter is not that robust if you have (  between "  "  or  {  the indentation fails too

It is a nice graduation project to write a really robust formatter

Analyse the output of the boot loader burning process?
compare it to avrdude output? (use commandline verbose flag?

disclaimer - Never did it myself
4  Using Arduino / Microcontrollers / Re: Cheap Chinese clone: Programmer not responding on: September 16, 2014, 01:41:20 pm

<wild guess>
maybe the boot loader and the sketch use (partly) the same memory addresses?
</wild guess>
5  Using Arduino / Storage / Re: HOW DO I STORE IN EEPROM longer BYTES on: September 16, 2014, 01:29:41 pm
split the int in two bytes  (use  /256  and % 256) and store the low and high part in consecutive addresses
6  Using Arduino / Sensors / Re: Has anyone solved the MAC 31855 high temperature instability problem. on: September 16, 2014, 01:19:32 pm
Did you connect the ground of the Arduino to the Ground of the kiln?
7  Using Arduino / Sensors / Re: Laser emitter: KY-008. Is it eye safe? on: September 16, 2014, 01:14:27 pm
Lasers are never safe, even a safe (low power) laser can fail in such a way it becomes unsafe.
8  Using Arduino / Sensors / Re: Set Resolution of analog-in and analog out using Matlab or Simulink? on: September 16, 2014, 01:11:02 pm
you can do oversampling  of the 10 bit signal.
to get an extra bit you need to sample 4x as much
2 bits extra => 16x as much samples

check this doc - http://www.atmel.com/Images/doc8003.pdf -

you need to implement this on the Arduino and you can define your own command in MATLAB to send to serial command to the UNO
9  Using Arduino / Sensors / Re: Looking for 1Kohm I2C Digital pot on: September 16, 2014, 01:07:29 pm
you can select easily at farnel  - this is a SPI device, but there are also I2C devices.

There might be a reason why those clone were cheap smiley-sad

Did the ebay seller offer support - special drivers - documentation that might be helpful?

Please keep the discussion polite, no need to get rude. 

@Nishant:
for commercial activities we have the gigs and collaboration section.

Personal opinion:
the student who pays for getting his homework done will in the end not be a good engineer,
I've seen  students fail their graduation because they could not explain the code they had "written" smiley


@Azizul90
You should give far more details about your project (goal, sensors etc) to get a meaningful answer. As a graduation project is showing you can act as an engineer you should come up with the criteria (requirements) to make the choice, no one can make them for you. When you have your requirements ready (unambiguous, complete, and testable) the choice of the board is just checking the specifications.
