Re: Streaming ... how come it's so slow?

The example seems to show that streaming is done using H.264 However it is still slow with a 3 second delay between my action in front of the camera and such actions showing on my laptop. I am using VLC to capture the stream from the Raspberry. Are these delays normal on a LAN? When I've done netwo...

Re: RPi timing system

Section 12 is timing, and it seems that It could possibly pass a certificate procedure if any exists. This is mainly for High School meets. Most High schools don't have a budget for a 2-3 thousand dollar FAT system, so even if this can only qualify for AT (automatic timing - 1/60 of a second) it co...

Re: Controlling 32 lights with the Raspberry Pi

Hi guys, I'm looking for a way to control 32 lights/(230V or 12V). I have been looking at the components to do this, but have been unable to find exactly what I am looking for. It might help to know what you're trying to achieve. One thought for that number of lights is to look at one of the protoc...

Re: gps receiver, ntp accuracy, battery operation

Hi, I understand that the GPS signal itself is stratum-0, but my question is more about the experience with the different receivers -- if you look at the link to ntp.org I posted in my original question "Unfortunately many of these receivers were not designed with accurate time-keeping in mind. The...

Re: Help: Wireless camera on a closed network

Hi, Thanks for the reply. I will look into it and try your method. Pretty new with the raspberry pi though. Just in case anyone is wondering, I want to create a surveillance system for the outdoors, where there are no wifi. I will try to power up my cameras with solar chargers, but I'd love to be a...

Re: Help: Wireless camera on a closed network

Doing this wirelessly without the need for Wifi at all could be difficult. You need some way to get the data from the pi to the tablet.

You could do it without the need for a Wifi accesspoint/router by making the Pi act as an access point itself for which there are plenty of guides available.

Re: Frustrated from the Raspberry Pi

It would be worth checking the quality of the cables / power supply you have. From what I recall if the supply drops below 4.7V the 3v3 regulator won't be able to supply 3v3 to the Pi (and most parts need a stable 3v3 supply). At 4.8V you don't have much margin left before that happens. I've tried ...

Re: Frustrated from the Raspberry Pi

Can you try a new USB power lead - I had power problems with a desktop power supply that turned out to be the cable! I'll be checking this now. Update - The XBMC problem persists. Also I've checked and the voltage is same (about 4.8V) as with the other cable. It would be worth checking the quality ...

Re: Female Headers for the IO Board

Sorry James, but I find it difficult to believe that the Foundation does not have, or cannot compile, a list of commercial partners/businesses that may or may not have previously expressed interest in a CM-like product and/or contacted the Foundation about incorporating a modified RPi in their desi...

Re: Female Headers for the IO Board

Sorry for hijacking a bit. Can't wait to see the business model behind this IO board. I am really puzzled. And no, I do not imply that I know better than the foundation or broadcom how to make money. In my work, I am used to deal with overpriced proprietary hardware(end user perspective), but it is...

Re: Low-level access to camera output?

I don't believe it!! I have just started to think about my project structure in a bit more detail, and looking at various facilities needed. I had just assumed that a "clever" board like this would have power saving modes for projects like mine which have very limited battery power. Now I have been...

Re: Low-level access to camera output?

So basically please be kind to an old duffer like me and tell me (a)Was the mention of 90fps referring to the video or still mode? (b)is the video mode the Raspiyuv you were referring to, if not, what is Raspiyuv? (c)what is the link to the code for Raspiyuv, and if there is more than one file on t...
