And I have one question about this relay :
http://www.emartee.com/product/41852/Arduino-5V-Relay-Module
The Omron relay can take 15A max according to the datasheet But can the PCB take 15A? :-/
Same question to the Mosfet board.
http://www.emartee.com/product/41874/Arduino-4-Route-MOSFET-Button-IRF540
Is one channel capable to be loaded  with 33A (FET AND PCB?) or is that total power?
And I find another relay on this website :
http://www.emartee.com/product/41894/Wrobot-4-Channel-Relay-Shield
I can't make sure of the difference of them ,and which one is what I need to purchase....... in trouble......... :-/ :-/ :-/ :-/

@Mowcius

I just want to show it to the guys who is interested in , I have no plan to manufacture about this ..... smiley-wink smiley-wink

I am tiding all the information about  Robot Camera  With  2.8" TFT , and I will open all the information including schematic diagram[ch12289]eagle file[ch12289]datasheet etc to you guys.... smiley
you can make  it yourself
or if there are many guys need , I will entrust one company or one shop to manufacture and sell at a best price. smiley-razz smiley-razz
Thanks for you care indeed. smiley-wink

How is the display is controlled on the board (with the arduino)?
Also is there a datasheet on the display somewhere (just the display).

Thanks,
Mowcius

Dear Mowcius
   You can use Arduino to control the camera to take photo[ch12289]to export and import the picture from SD and TF card[ch12289]to read and display pictures from the SD and TF card. You can also use Arduino to control the camera to be your robot's eyes..... smiley-wink and you can extend other function of this camera. smiley
 This camera can also be compatible with some equipment.
  We will release new version soon ,which is more powerful than this version......
 More information will update continuously...............  

Regards

Can I get any info on the display?
Would you please tell me more about what you want to learn?

I never had any doubts that it could display the camera picture on the screen, but how exactly does this involve an Arduino ?
Well I was querying the fact that it would do all that while being controlled by an ATMega32 (yes 32).
Quote:
I do however doubt how fast this camera, screen module thingy will be.
I think that is pretty impressive.

The arduino would just control the taking of a picture and whatever else you want it to do as far as I understand it. The onboard ATMega32 controls the camera and screen (and storing of pictures etc)

Could the camera be connected to an arduino, data sent via XBee and then the data sent to the screen for the screen to display it/take pictures etc?
Any news on availability or pricing yet?

I would be interested to know more about the display as it is obviously cheap and relatively simple to interface with. Is there any more information available about the screen itself and how it is interfaced with?
Can I get any info on the display?

Mowcius
Yes, you are right. You can use Arduino to take pictures. However, you can also use the ATMega32 to take pictures.

Yes, camera can be directly connected to Arduino. And then data is send to the display wirelessly and display it.

Any news on availability or pricing yet?
now we are still testing it. Once testing is finished, price information will be updated here smiley
And the display can also be directly drived by Arduino. smiley

Well, you can see there are still many vacant pins on the control board. You can expand the function to work with Arduino. smiley

Well, soon i will upload a piece of video demo in Youtube. It will tell that it is true.
Make impossibility possible. That's the art of technology. smiley-wink

I'm wondering how you are going to make any headway into a VGA camera's image which is about 1MB native and about 20-30k as a jpeg with an 8 bit processor with 2kB of ram.  The arduino will probably take 10 minutes to establish if a frame has any blue in it......

It's pretty obvious that many people here have a very limited perception of how seriously low powered an Atmega microcontroller actually is.  

Hint : your computer has a million times more memory and storage than a Duemilanove. (literally)
11  Forum 2005-2010 (read only) / Development / Re: Robot Camera  With  2.8" TFT on: April 22, 2010, 10:02:56 am
It already has the function of storing image data to SD/TF card which is connected to it. smiley

I'm looking forward to the new version of this module
and I'm looking for the same kind of module to use with my
robot, which compatible with my arduino.
How to achieve that put the picture into the storage
of arduino small space?

expect your reply.Thanks

To mowcius :

Our module is more powerful, it can achieve:

- TFT take a photograph real time when you need
- show the picture at the same time
- storage the picture you take automaticly
- read data from SD card;
- read data from TF card;
- send data to LCD screen for display;
- read touchscreen input;
- control touchscreen input by a button
- get time from RTC.
- and some other more update

We will release new version soon ,which is more powerful than this version......information update.......

To Jackson :
 
   Thanks for care.
   You can use it with Arduino by USB interface through Mini USB or Sonsor shield shield.
   You can also connect it to your computer directly by USB cable.

To sciguy

    It can do some image analyzing like blob tracking or color tracking when you use with Arduino[ch12289]Arduino sensor brick[ch12289]Robot special sensor . smiley

We make this Robot Camera Kits  With 2.8" 65K touch TFT Display (Arduino Compatible)

It includes camera, screen and control board. Control board is placed on the back of the screen. Camera sensor generates image data which is then processed real-timely by control board and displayed on the screen.
The Screen is 2.8 " and 65K color, supporting touch TFT function.
Camera is 30W Pixel OV7670 camera, which can supuly distinct image for normal use.

Control board is integrated with Atmega 32. So it is compatible with Arduino, which makes it possible to communicate with Arduino easily.
Many interfaces on the control board are still reliable, including 4-channel ADC, 1 channel USART, ISP port and 2 channel PWM, which makes function development much easier. smiley

5V power is supplied to the control board via USB port, without any special requirement for power module.
OV7670 screen's power supply is 2.8 ~ 3.0V, which is TTL level for most of MCU.
TD/SD card can be connected to SPI port, which makes image storage possible.
Camera interface is plug-in mode. It is very easy to connect or disconnect with control board. Control board and camera can be used separately. smiley



















Our module is more powerful, it can achieve:

- TFT take a photograph real time when you need
- show the picture at the same time
- storage the picture you take automaticly
- read data from SD card;
- read data from TF card;
- send data to LCD screen for display;
- read touchscreen input;
- control touchscreen input by a button
- get time from RTC.
- and some other more update

We will release new version soon ,which is more powerful than this version......


More information will update soon............... smiley-wink smiley-wink smiley-wink smiley-wink
