his task is to make a circuit board that would connect the camera and the display right ????
Exactly.
and btw he ask me to asked you what kind of an out put does the 12C give ??? AV orrr????
It's not 12C. It's I2C (i2c - inter-integrated circuit). It's a protocol where ICs can be connected directly without supporting hardware. So the data is sent through I2C bus from the camera. Please forward him the datasheet of it so he can figure out what data is coming from it.

On the easy way, you can ask him to join ROBOT.LK ;)

48 LED illuminator light CCTV IR Infrared Night Vision
Item description says Powered by DC 12V 500mA adaptor ( not included ).
So this is possible to run with a 12V battery. You can use a 12V 7Ahrs UPS battery quite fine.
There are smaller ones with less Ahrs (Ampere hours) as well. Less Ahrs means less time you can run with them.

There is no description about the power source. However I guess this is powered with 12V as well.
If that is the case, you can power that with same kind of battery. Just question the seller through eBay.

ah ok then , but i forgot to mention ...that battery will be giving power to a LCD display (i still havent decided the size) and to a i2C cam .... so will that battery provide enough power ??

No problem at all. You can use the same battery (12V 7AHrs... The same battery is inside UPSs). You can also buy a little charger to change when required as well.

Rasanga asked me what is this AHrs thing.
One ampere-hour is equal to 3,600 coulombs (ampere-seconds), the electric charge transferred by a steady current of one ampere for one hour.

He also asked me the dimensions of the UPS battery I mentions.
UPS batter (12V 7AHrs) dimensions: Width 65 mm, Depth 151mm, Height 97.5mm. Weight 2.65 kg
Cost: ~LKR 2000

Since Rasanga told me the UPS battery is large for him, I'm adding some small batteries.

hey guys ...I've purchased these items

http://www.ebay.com.au/itm/Rectangle-In ... 331wt_1139


http://www.ebay.com/itm/DC-12V-6500mAh- ... 0876857317

im still deciding on the display , most probably I'll use something close to 9-8inch LCD display ;)
and thats all i need i suppose , SO here's what im going to do ... Im going to fix the IR illuminators on to a biker helmet
, then fix the CMOS cam somewhere near to that and afterwords fix the LCD display on the helmet shield then connect them both via some kind of circuit or a converter ..
then plug them both into the battery which will be placed at the back of the helmet, and thats about it


so any ideas ? comments ?? will that work ?? and Im still a bit unclear about the CMOS cam thing , how should it be connected to the display ?? I asked another person who will be providing tech support , and he's not very familiar with that,
he told me to use a rear cam , MY QUESTIONS ARE .. which is better ? if I chose
either one of them , how should i fix the circuit ?? what kind of INPUT and OUTPUT should the LCD display have ?? and as another sub question , does the CMOS cam have the ability to take in video feeds from about 10-15m distance ?? IF not , can you suggest anyother cam which would be suitable ? :idea: :idea:

I guess 7" even enough. You should leave some space for the bracket you are going to fix it to the helmet.

Sounds like a good plan.

Your electronic designer must decide on that based on the interfaces you have on your devices. CMOS cam is I2C and most probably the LCD would be parallel. He will have to decide on a microcontroller which has enough ports to handle that.
what kind of INPUT and OUTPUT should the LCD display have ??
Usually parallel interface.
and as another sub question , does the CMOS cam have the ability to take in video feeds from about 10-15m distance ?? IF not , can you suggest anyother cam which would be suitable ?
Since I haven't work with the camera you bought, I can't tell you anything. If a datasheet is available for the camera, just check whether they mention about that. You can also send an email to that company on that.

Once you bought the LCD, I think you have everything you need except the main circuit. You will have to use a microcontroller to connect the I2C CMOS camera to the parallel LCD. If you could ask your electronic designer to submit his plans on the circuit design, we can help you with some ideas.

hi,
This is soo possible using a normal web cam.I'm telling this because one of
my friend built that.

web cams are come with a IR filter. Where you can easily do that conversion but
not easy in some cams, because in some chips the filter is placed inside the CCD
chip or more closer to it.

I'll already mailed my friend , hopefully I'm waiting for a answer now.

Sandun,

Rasanja is going to build something for an exhibition. He needs to fix a cam with IR illumination and get the output to a little LCD fixed on the helmet. Everything is battery powered so a person can wear it. Rasanja is almost in to the final steps of planning his project and he needs to discuss with his electronic designer on the microcontroller they are going to use, etc....

Since it seems you haven't read the topic form the beginning, it is recommended for anyone who thinks to jump in to read from the beginning. Otherwise it can be disturbing for all the participants. It is not required to answer all the posts. Please answer only if you know (no need to ask from friends and submit here since we have professionally qualified members in every engineering discipline we discuss here.. just ask your friends to join with us).

We need to keep ROBOT.LK with highest possible quality.

I hope you'll understand ;)
