Re: Custom Li-Ion vs SLA Battery

When size and weight aren't an issue, I'll always go with SLA. They're easier to charge, relatively inexpensive, charging circuits are simpler, and as long as you keep them topped up they'll last a long time before they need replacement. They're also less likely to fail catastrophically if there's a...

If your Pi isn't running anything important, or if you don't mind rebuilding it if things go wrong, you can update the firmware ...

I print and cut my own boards and little tags like this happen every once in a while and don't impact the function or lifespan of the product. The previously mentioned file method works, or even just take a pair of small side snips and carefully lop it off.

Hello everyone, Just wanted to drop a quick post...

Re: Official V4L2 driver

This is fantastic! I've now had Motion running at 2048x1152 for the last twelve hours straight. The ARM is sweating a bit, but I've overclocked to 900MHz and it's running at a very good 2fps (Motion's a bit of a pig).

Thank you all so much for the work you put into this!!!

Re: image goes black after a couple of minutes

Totally expected as you've told Motion to capture YU12 images. With any of the raw pixel formats (YUV or RGB) the driver makes a guess as to what you're using it for based on resolution. If <= 1280x720, then it assumes it is video mode and effectively runs it as preview/video encode at whatever fra...

I'm not sure if this is the best place to post this (and I apologize if it's a repeat of other work), but I found something interesting about the picture going dark when running Motion. If I run it with resolution 1280x800, it goes dark within about five minutes. If I run it with resolution 1280x720...

Re: pi noir behave like the regular camera board (indoor)?

It can be tough to tell under bright light. I don't know if there's any difference from an electronics or firmware standpoint - I think the only difference between the regular camera and the NoIR is the board colour and whether it has an IR filter built-in. One thing you can try is pointing the came...
