Where can I buy a camera to connect over the CSI, or a display to connect over the DSI?

If you just say eBay, can you tell me what i would search for?

The particular cameras/displays have not yet been decided on so at this stage you cannot buy them. Once the boards production is all sorted and up to speed the foundation can spend some time on peripherals!

Part of the problem is the you will need an adapter boards for the Pi to the particular camera being used - and those simply haven't been designed yet. Camera's don't just 'plug in', they need something to plug in to.

Just for fun, here are some cameras to give you some idea. The one on left is already mounted on an adapter board (not one that fits on Raspi)

o sweet

I thought it would be more like a developers board where you have to go find parts to put on it.

Could you give me a ball park on how much? (ex $1-$30, $31-$75...)

No idea on price. This is a problem - usually the camera manufacturers only sell in VERY large quantities if you want a sensible price. Look up the Nokia N8 camera on Ebay for a ballpark - that's pretty high end, so should be less than that. No promises!

It would be really nice if someone with proper skills creates interface boards for diffident cheap lcd displays like ipad, NDSi, N800...

I DSI norm just about electronics or also about physical connectors ?

It's about the signal (and even that needs tweaking), I think the connectors vary wildly, hence the difficulty.

Prices for the cameras is quite low. Spare iPhone 3G camera is about $6 in a shop near my home. Also you can buy virtually any camera on china online shops, like aliexpress.com or dx.com
Just as example - 5 iPhone 4G cameras for $10 - http://www.aliexpress.com/product-gs/50 ... alers.html
So, there are only three questions: pinout? drivers? compatibility?

One last question - has it been tuned already by Broadcom (or is it similar enough to an existing tuned device)? Which does limit the options a lot. Tuning is absolutely necessary or the pictures are awful.

I believe:
- the iPhone4 rear sensor is a 5Mpix Omnivision OV5650.
- the iPhone4S rear sensor is an 8Mpix Sony IMX145.

Interesting, thanks. Not sure we have tuning for those, but we do have tunings for similar ones. Problem is, similar isn't usually good enough - even modules from the same manufacturer that appear the same can require very different settings. For example, on some Nokia phones, where they had multiple sources for the same front camera, we had to tune each, apparently identical sensor (to the end user), separately.

please, please, please read viewtopic.php?f=43&t=6691&p=103483#p103483 and leave the tuning to the community. Spend YOUR time on something we need YOU for.
Give 1000 raspberry pi users a small app with 16 knobs, and someone will come up with the proper tuning matrix soon enough. (for B&W there are a only 4 relevant parameters. So tuning will be easy. Release the camera with: "B&W works, but we're confident that color works too")

The same thing would be nice for displays: please release code for just turning on the DSI, and let the community do the rest of the tweaks and tuning.
I've seen people hack into all kind of phone displays, in my many searches on the Internet, and I know there is talent out there waiting for a shot to do it.
I don't think that the priority between the CSI cameras and DSI displays should go to the former, as the displays have a lot more applications.
Also you don't have to do any kind of marketing research. People will find their own displays from various sources, and if a mass-produced cheap display is needed as another revenue source for the Foundation, it will also be there in the end.

I 'ts a pity that so much effort was put into developing such a powerful hardware platform and not enough on the display issue.
It doesn't make much sense to spend 30€ for the main board and have to spend 100€ or more to get an HDMI display or a HDMI to VGA adapter.
I don't think many of us have access to video composite monitors anymore.
I actually find it a waist of resources such a perpheral.
This board is particulatly suitable for embedded applications with small displays.
My opinion is that until there will be access to a resonably cheap display with DSI interface, this platform will not have the diffusion it deserves.

Yes, for a good one.
There are cheaper ones too but not recommended, according to comments I found on the web.
Maybe you want to try, in case let us know if you find a good and cheap one.

You own a television do you not? Even the £1500 tv someone I know just bought has a composite input. All the TV's in my house have one.

I have no idea which rock you have been living under but i do not know anyone who does not have a TV with composite video. and about half of those people have HDTVs, including me.

http://www.ebay.pl/itm/ws/eBayISAPI.dll?ViewItem&item=251086464644 I've bought this one. Monitor is detected automatically, but sometimes RPi requires a reboot to set optimal settings (I guess RPi boots quicker than the adapter...). Forcing settings in config.txt works every time. The is a (small?) problem with D1 diode getting hot as described here: http://www.elinux.org/RPi_VerifiedPeripherals#HDMI-.3EVGA_converter_boxes but it doesn't go too hot to touch. Other adapters are also listed there. Hope you'll find something useful!

Just to increase your options HDMI and DVI are electrically identical, so you can buy HDMI to DVI cables for a couple of quid on ebay.

All of my televisions (even the new panel type) have composite, component and HDMI input.

As for such a powerful platform having shortcomings, remember, this board was designed arouns a budget, not features. It has all of the basics already there (I/O and networking), provisions to expand within the limits of the platform, and provisions to expand the platform (through the GPIO).

All-in-all, the RPi is an amazing device. Yes, competitors like Arduino have more options, but they have been around longer and have the development time to show for it. For a truely hobbyist system, the RPi has a robust core structure. It is now up to us, the hobbyists, to develop the expansions and share our designs with the world.

Some small progress...
Whilst James H is off on his travels, Gert gave me a 5Mpix camera last week, and I brought up the driver and put in a basic tune. So that has proven the HW interface and camera board design. Well done Gert - it worked without needing any HW mods. We now have to do the plumbing to make this visible to linux...

Gert. Is there anything he can't do? :lol:

On the plus side, the holidays are almost upon us. I'm keeping my fingers crossed that I get an RPi for Xmas. If not, it will be my present to myself.

I really can't wait to start playing with this thing. There is so much potential, if you (meaning "we") are willing to do a little work. I haven't been in "hardware mode" in years, and seriously craving the smell of molten solder. ;)

Yes, he can't write camera drivers....
