[PICS!] Inside the canon 1100D
« on: October 28, 2012, 03:31:25 PM »
Changing the crystal is too much work, not worth opening the camera and might not work.

I've overclocked a bunch of ARM router + phone stuff and if you go past a point the proc just doesn't boot.

Well i think it cold be worth the risk . I think i cant resist ;) Just bought a broken 1100d for experimenting.

About 7 Years ago i ylso overclocked my Nintendo Ds by adding a different crystal that could be activated with a switch.

Im also not shure what will happen if we change the clock.

Do you have a broken 1100D? I've been looking for one for a LOONG time  :-\

Before killing it for good, If it does not boot, I'd like some macro pics of every single PCB board and connector in there and run some tests to find the serial (UART) port (by probing the battery bay pins with an oscope or something similar)

I don't think there's a warranty for that.

Nope, that's definitely not covered.
Hardware vendors like to place "water-sensitive paper" that changes color in the event of water damage just to avoid this kind of situation.

And i guess corrosion from salty water or just mineral water is definitely obvious for anybody who can diagnose a failure in such a device.
I had found a 500D with a 18-55 IS on a used market forum. Shame it had been sold. Both things were not working. 18-55 IS could be repaired with a spare flat cable for AF (did that, so easy to fix mine a year ago) and the 500D looked like it had a dead shutter. You can find it on ebay for about 40 euros and doesn't seem to difficult to replace it.

The corrosion is usually obvious no matter what.

The pictures aren't very clear, can you write down the text from each IC?

Thanks for your hard work, here are some commented pics (I need more details on the unknown chips, one of them will probably be the audio IC)











Note: Looks like there's place for an IC, I wonder what that is. Also: lots of test points....

The second one looks like an audio chip (is that a jack and the upper connector for the microphone?) .

I was talking about this.
The form factor of the chip is the one of an audio IC and the connector directly above should be for the microphone.
The one on the right could be the  shutter release, as it is an entry level camera.
