Re: Listen on a GPIO pin for incoming voltage?

@Grumpy Mike: I bought the resistors from someone who told me they'd be suitable for taking a 12V power source and driving an LED which normally expects something lower (like 3.5v?). I may well have got the terminology wrong. And yes I may have got the terminology wrong on the wiring but you still k...

Re: Listen on a GPIO pin for incoming voltage?

Thanks for the replies so far :) I would have posted a reading of the voltage but I can't find my meter! The power brick that goes into the alarm is 9V and incase of power failure, it falls back to an internal battery which is also 9V. When I connected an LED without a resistor, it lit for a split s...

Listen on a GPIO pin for incoming voltage?

Hi all, I've got an alarm system that can have an additional external siren attached. I've connected a couple of wires where the siren should go (siren+ and ground-) and then used a resistor and an LED. When the alarm goes off, the LED lights up and stays lit until the alarm is disarmed. I was wonde...

Re: Local Youtube

Well since Youtube is owned by Google and Google own the android market place, they can easily say that they're not going to let any apps in that download youtube videos. Obviously the raspberrypi doesn't have these same restrictions. It's very hard for them to prevent people downloading the video f...

Re: Local Youtube

I've updated the scripts to also download any youtube video on http://www.reddit.com/r/videos So not only will my youtube subscriptions be downloaded automatically but I'll also get the latest 'trending' videos from reddit. The great thing about this is that it will just check youtube and reddit eve...

Re: Local Youtube

So a bit of an update. For improved reliability, queuing and download speed, I'm now going another route. I'm using php to collect my subscription feed and pull out all the new videos. These video links are passed to phptube which then turns the direct download link. I'm then feeding those download ...

Local Youtube

I thought i'd start a topic about what I'm up to because other people might be interested, might have suggestions or perhaps have already done this..! I have my raspberry pi powered from the USB port of my Apple TimeCapsule (router/backup) and it also gets its internet connection from the LAN of the...
