Re: any recommendations for a USB microphone

I'm a little late to this thread but will add: I decided to see if I could get the mic on my MS LifeCam hd3000 working. I have 2 rpi computers setup with medium overclock (700-900mhz). I grab the sound off my outdoor aviary webcam (rpi1) and pipe it to the indoor rpi2 using this syntax on rpi1: arec...

Re: Setting up a simple firewall for use in the DMZ

UFW has worked out very nicely for my small need. I'm using a usb webcam on a v.2 rpi dedicated to viewing my outdoor aviary. I wanted to view the aviary not only from my home network but also on the internet away from home. The home router does the heavy lifting as the primary firewall. I didn't se...

Change LXterminal startup

Perhaps other beginners might be interested in tweaking how the LXterminal session starts. I particularly wanted to change the number of rows. I found I couldn't do this by right clicking on the window and changing preferences. After searching a bit I found I could modify ~/Desktop/lxterminal.deskto...

Re: Using a Powered USB Hub

NO. Well, at least mine doesn't. I have a common DLink DUB-H7 7 port, 3 amp powered hub. When I disconnect power from the micro usb power connector to the rpi, the rpi's LEDs turn off! If the rpi is powered down, and the usb hub is powered down and the rpi plugged into the hub, if I turn on the hub,...

Re: Prevent SD-Card Corruption

Just catching up with my posts. An interesting thing was mentioned was running the pi "ro", read only. As I have begun regularly backing up my images, I move the little mechanical slide on the sd card to "lock" (read only) to make sure my use of Win32DiskImage.exe (on win7 pc) doesn't accidentally o...

Re: Raspberry Pi does not turn on

OK, sounds like its working normally. BTW, if you're using wireless, you'll only see the red and green LEDs. With no keyboard/mouse activity, the idle-time-out limit will occur, and the screen will "turn off" while in the x-window. Pressing a key will turn the screen back on, bring it out of screen ...

Re: SD Corrupt

very difficult to actually read your screenshots. the print is too small. I have also had some problems with sd corruption. I keep generations of copies of images, just in case a bug sneaks in and I have to start again from a known good point. The problem happens most often on a headless rpi when it...

Re: Initial Problem

I don't use NOOBS but have some frustrations with beginning using the rpi. The main problem has been with power supply causing weird failures I couldn't identify. After changing to a stronger PS, nearly all strange things have gone away. So some suggestions. If you are using a usb hub, it must have ...

Re: Motion and Firefox memory leak

Yes this is a bug (tho little understood apparently by Mozilla) in Firefox (or iceweasel for rpi). I mentioned it in this forum originally because some new users (like me) may think the problem is associated with the rpi or the motion program, and wonder what they are doing wrong on the rpi. Indeed,...

Sorry for delay in reply. The wifi dongle on the aviary rpi is a Netgear stubby usb dongle I picked up at a local store.

Re: no access to motion server

Things to check that may be missed: 1) if the pi is wireless, and you have forced MAC address control in the wireless access point device, modify the wap to include the MAC address of the wireless device (dongle) attached to the pi. 2) if you want to see the MAC away from home, like at the local cof...

Re: Any Wi Fi signal Gurus out there?

Definitely not a guru, but have been messing with the pi and wifi a bit. I have an outside pi which sole purpose is to run motion with a usb webcam pointing at aviary (207.127.177.81:8081 using firefox). This pi is both headless and wireless. For several weeks the pi would loose its wifi signal stra...

Re: Consider a USB camera as an alternative

I concur. On my first pi, I hooked up a usb M$ livecam hd3000 and used Motion to view my outdoor aviary from other computers at home and via internet with tweak to router forwarding. Worked decently. So I thought I'd get a 2nd pi with a pi camera module and try to do the same. I worked at that proje...

Re: Unreliable Unreliable Unreliable

I have had numerous SD card corruptions. Some were caused by removing power on a stuck headless, wireless, minimally powered pi far from the router/hub/switch (outside aviarycam). Some were just strange glitches probably attributed to me learning the pi. You know its corrupted when the pi boots with...

Re: Prevent SD-Card Corruption

Maybe a little late to the party on this one. After doing a normal shutdown, and the system says its halted, there are a few extra moments when the green led flashes 10 times on my pi rev2 512MB. I suspect there's disk activity going on even after the system says its halted. If one removes power dur...

I setup a MS LifeCam HD3000 on a rev B rpi. It works decently well with the motion program. I currently stream 800x448 (modulo 16 safe) images of my outdoor aviary to home network and on the internet. While viewing the stream with Firefox 23, my 2 windows 7 PCs would sometimes crash after viewing fo...
