Re: Rpi Camera vs. PiNoir: Normal Colors + Infrared?

Thanks!

Is there infrared light of some specific frequency that is 1. invisible to human eye and 2. can be picked up much more strongly by the normal Rpi camera than in the picture you've given?

Or any other way to have "normal" colors plus infrared illumination?

Rpi Camera vs. PiNoir: Normal Colors + Infrared?

I understand that the PiNoir can pick up infrared light but the colors are altered. Is it possible to have normal colors and additionally pick up infrared light? Such as is happening in the following video: http://youtu.be/SHbwi6JP7FM?t=50s (the webcam picks up the infared LEDs of the headsets). Tha...

Re: Mobile Pi - Power Solution?

Sorry, I wasn't clear enough. I mean, whether solutions exist that shutdown if the power is getting low or that supply extra power in an accident of power loss.

Mobile Pi - Power Solution?

In the past I had problems with sudden interruptions of the power supply. Led to corrupted OS.

Are there scripts out there that manually shutdown the Pi or even better custom hardware solutions?

Thanks very much!

Hey, I autostart a python program to run my Pi mobile without visual input. I mistakenly disconnected the Pi of the battery pack. The error message: "No filesystem could mount root, tried: ext4 [ 2.04266] ... Kernel Panic - not syncing: VFS: Unable to mount root fs on unknown-block(179.2)" My Pi is ...

Re: vertical artifacts in low light condition video ...

I had horizontal artifacts, flickering, banding in low light conditions. When my Pi was connected to the wall's power supply the power cable's length was irrelevant. Connected to a battery pack though, the power cable's length plays a role. I now use my mobile Pi camera only connected to the battery...

Re: HDR raspivid and raspistill

Thanks for the example.

HDR is a skill that depends on the context of the photo. One could clearly maintain the contrast of the first picture but also lighten up the annoying drowning bits.

Re: HDR raspivid and raspistill

Thanks for your answer and sorry for not clarifying.

Besides the firmware, there wouldn't be any other way? Am I right, that the manual exposure is not yet implemented in the cameraboard firmware?

attach a LED + resistor to a unused GPIO pin and flash it each time you write? or if you have the LED on the camera you can see it flashing or use a texy lcd shield and write to that Thanks for the ideas. The led on camera I cannot use. Texy's shield looks promising. Stick a bluetooth serial adapto...

I have yet to decide what microphone setup to acquire but I would like to know in advance:

In what way is it possible to sync a video generated by the camera board with an audio file generated by a microphone?

Hey Leo,

you did attach the fisheye lense of the mentioned pack of three lenses? Would you be so kind and post a photo with the "wide angle lense" contained in the pack?
