[cow_theboy]

ela ela machooo

[chamithal]

We did a nice one - A heater controlling system.... Where we can plugin a conventional heater and heat to a given temp upto a .5'C precision... he he! cool ne... I wrote the programme.. it was a cool job..........

[Sasika@Elakiri]

Bro electronics monawahari igenagannawada??


Macho equalizer displays ganna thanak dannawada??


Ela wor kmacho, keep it up, speacially do that mp3 project and share your exp with us

Elakiri. Bud what did u use for disply. SEVEN SEGMENTS OR NICE LITTLE LCD.:D

At the moment im not doing anything.

Equalizer rady made ones nam not sure in SL. But u can make it Using Grapichs Displa AND PIC OR AVR. ( I recomand AVR )

and about that CAR MP3 PROJECT.

I have a knowledge for make it. But finding parts is the hardest part in SL.

Main problem is Finding a good 7" touch LCD.

and the other problem is finding electronic parts for make 12V power supply for CAR PC.

[icreations]

Wow... Cool... keep it Up Dude...

[kepu]

Weldone Brother ... good luck

[icreations]

Cool dude...

Elakiri. Bud what did u use for disply. SEVEN SEGMENTS OR NICE LITTLE LCD.:D

7 segment... it was enough.. tht one was our L2 june term project and was selected as the est one.. it could even boil any liquid by (u knw tht water boils @ 100 in 1atm n it waries with pressure ne.. + liquids like oil boils @ different temps ne.. no matter wht the liquid is, it identifies its boiling point... he he....)

We ddnt even use a 7 segement driving IC - we had a 28 pin 16F876A as I remember... so enough pins ne.. he he...;)

So long bro...

[Kasun007]

Why don't u use a LCD for this one.I think LCD is better than 7 seg for this.

Finding the circuit parts in SL is hard thing.which PIC u use for this?

[ashenrandika]

Wow max bro... dont you like port programming????:D :D :D :D :D

[rukshankb]

wow Good program me!

I also make LCD clock.

It has date, time ( HH.MM.SS ) and alarm.

But bro at knight LCD is not good enoughf.

May mage 2 weni project eka,

Is that a 3310 LCD or what?:love:

I also made digital Temperature Meter using 3310 LCD few months ago.

PIC12F629
DS18B20+
3310LCD

Powerd by two 1.5V bats.

I think u know about that project.

These r not my pics
