Re: Home Alarm System Retrofit - "Part Deux"

Hi Guys, It's my first time here. I have started looking into RPi stuff few weeks ago and so far I am happy with pbx and xvmc. Not sure if you've looked into the sensors from Ubiquiti? They have quite few useful bits in their mFi range - pir, door sensors and temp/humidity. I have ordered samples a...

Re: Home Alarm System Retrofit - "Part Deux"

Thank you for your thoughtful reply, damauk. I've been running this current configuration for a few days now and its clear the next improvement I need is a kind of sensor grouping like you're describing. I had initially thought I would give each sensor a group index (by adding a field/collumn to my ...

Re: booting from class 10 SD doesn't work

I installed (at separate times) both Wheezy and ArchLinux onto an 8GB class 10 SD card. In each case the boot starts okay, but gets stuck. Is there something wrong with trying a class 10 SD card? I have found that class 4 cards work fine (I've used up to 8GB). While I'm here, how does one change th...

Re: Home alarm system retrofit.

Polling GPIO with Python is fine if the signals you need to read do not change too quickly. If you poll using C, you will see several orders of magnitude increase in speed. (or far less CPU used if you throttle the polling.) For a home alarm system, Python should be OK. You're absolutely right. If ...

Re: on-line resize of /dev/mmcblk0p2 hanging

FWIW - Resizing my 32G Adata card seemed to hang too. (I left it for several hours.) When I moved to a higher output power supply everything (resize included) seemed to work better.

Anyway - If the resize seems to hang make sure your power supply is adequately rated.
