Python code to detect if camera is available

Hi

I'm looking for a way to detect in Python code if camera module is connected to RPi. I have a script which start at boot to take pictures for timelapse, but when I run Pi without camera connected it causes errors.

Thanks in advance for any clue.

Re: F3 Poly Fuse casuing my problems?

First of all you can try to contact distributor and ask for replacement. If you can't do that (or doesn't want to) I think that you should try replacing that fuse. I did it myself and I'm far from being proficient in soldering. It's not really a big deal and if you won't try you will never improve y...

Re: Raspberry Pi Camera Module Causes Reboot

Mine is Rev. 2. And after additional tests I can confirm, that proposed solution solved my problems.

Re: Raspberry Pi Camera Module Causes Reboot

No, I have never messed with overclocking. But I will try to disable this current protection and see what happens. There is also proper stability test on this site, I will try this as well. Thanks for response. EDIT I had only few minutes for testing, but after disabling current protection in ./boot...

Re: Raspberry Pi Camera Module Causes Reboot

In my case it seems like the problem is related with shortage in power when GPU is in use. My model B Pi restarts just after trying to render some graphics. I tried to perform a stress test involving a lot of calculations for a long time and it passed it without problem (although I have no idea how ...

Re: Raspberry Pi Camera Module Causes Reboot

My Pi model B have similar issues. It restarts just after I try to run raspistill or raspivid. Also, it restarts when I try to run Minecraft. I have tried many PSU's rated above 1A without any luck. Except these two cases it works normally. On my second Pi (model A) I use camera and run Minecraft wi...

Re: Reboot when loading games / graphics

Are you guys using cases for yours Pis? Yesterday I tried to take out mine from RS Components case and realized, that during this operation whole board bends. The same is when you are trying to put it inside. Maybe that's the source of problems – some micro-cracks created due bending.

Re: Reboot when loading games / graphics

I have tried different cards with no difference. Yesterday I have also tried powering Pi from GPIO, with same results. And becouse I have lost my invoice, I have replaced F3 polyfuse with a piece of wire. Now I have voltages greater than 5V, but after starting Minecraft Pi still reboots. Probably pr...

Re: Reboot when loading games / graphics

Hi, have you got any success in solving this issue? I have exactly the same problem - my Chinese RPi from RS Components reboots after running Minecraft or OpenArena. To this day I have tried everything what I could think off. I have checked five power supplies (including "official" one from RS Compo...
