Re: What to remove to minimize Raspbian (no xserver)

I know this is an old thread, but I wanted to say thanks to the contributors. I'm using my Pi as a stand alone security camera, and having loads of extra space to store videos and pictures is a god send.

So thanks for your work. Much appreciated.

Re: Wifi + Raspberry Pi camera = no SSH

Thomas, Thanks for the suggestion. I've actually done a few things today. First thing I did was: sudo apt-get purge ifplugd which reduced the problem significantly. I've got the videos being stored on a NAS box in the house, so yes the wifi limitations could be causing it, but looking at the Watch c...

Re: Wifi + Raspberry Pi camera = no SSH

So I have replaced the power supply with a 5V 1.5A power supply with a tortuously short lead on it. Its better, but still not great. I've done some experimenting and I've narrowed down the fault a bit more. I'm using the Model A with an Edimax wifi mini dongle and the Raspberry Pi Camera Module. I h...

Re: Wifi + Raspberry Pi camera = no SSH

Thanks both for the suggestions. I think part of the problem as well is the length of the cable. I'm using a 3 meter one now, which I think is also contributing to the problem. Need to rethink my positioning I think.

Re: Wifi + Raspberry Pi camera = no SSH

So after much frustration and digging around, the problem is (as pointed out) the power supply. As soon as the camera kicks in, the wifi dies. But the issue I have is what power supply to purchase now? The Raspberry Pi FAQ states: The maximum power the Raspberry Pi Model A and B can use is 1 Amp, so...

Re: Surveillance camera based on BuildRoot and Motion

Hi allenjh, What camera do you use? Is it CSI (RPi specific) or a normal USB webcam? If it's a CSI camera, make sure you connected it in the right connector and with the right side. If it's a USB webcam, could you tell us the exact model of the camera? Moreover, could you ssh into your RPi and tell...

Re: Surveillance camera based on BuildRoot and Motion

I like the idea of this very much and it seems to be well liked... however! When I fire it up, I can connect to the page just fine, but it doesn't see my Raspberry Pi Camera board. If I click on Add a Camera, it isn't listed there either. Am I missing a trick here?

Many thanks,

J

Wifi + Raspberry Pi camera = no SSH

I'm setting up my Model A with an Edimax mini WiFi dongle and Raspberry Pi Camera as a security camera system. I've set everything up and had the system running without the camera installed. Happily SSH in and setting everything up. I then connect the camera and I can SSH in for a couple of minutes ...

Matt, have you had any feedback on this one? I'm in Torbay so its a bit of a trek, but I'm keen to see if this goes ahead or not.

Re: 2.8" TFT + Touch Shield Board

Thanks Texy, that worked a treat.

(for anyone else reading this with a similar problem, I shutdown the pi, disconnected the HDMI, SSH'd in and ran the program, then used the shutdown command to turn it off then plugged in the HDMI so I could post this reply!)

How big do you want? If you want really big, you could always look at the touch screen overlay kits you can get. I've seen those all the way up to 65", but I'm not 100% sure how they would work with the Pi....

Re: 2.8" TFT + Touch Shield Board

The Pi's dimentions are: 8.5cm x 5.6 cm The TFT's dimentions are: 7.9cm x 5.4cm On mine the TFT sits almost inside the Pi's footprint, only having about 2mm overlap outside the Pi over the GPIOs. The Solar charger case from Cottonpickers won't quite hold this and the Pi as it overlaps a little, but...

Re: 2.8" TFT + Touch Shield Board

Hi Jeff, yes to both questions. The display itself isn't much smaller than the Pi's footprint, and although it is obviously connected directly on the GPIO port at one end, nothing else connected at the other. However it does rest nicely on top of the USB port - Model B's twin connector anyway. In d...
