Re: powering USB peripherals

Hi there Very interesting regulator you have found there, sure looks like it will fit the bill, and a good price. A couple of points come to mind. If the regulator is adjusted to give 5v out, I expect it will still operate with the input down to around 7v or less. This would mean if left connected t...

Re: Switching Composite output on the fly

Not sure if this is of any help but in fact to get 24fps films to 60Hz NTSC s system of 2:3 pull down is used where by one frame of the film has 2 fields scanned from it but the next has 3 so causing judder on fast pans. For 50Hz PAL the film is simply increased in speed to 25fps and each and every ...

I have a project that I think the Pi will be suitable for and hopefully introduce me to programming. I have a 1 off project to read the state of 4 switches in one location and send ...

Re: what resistor do I need?

Hi Just spotted your post. Please make sure the supply is a REGULATED 5volts. An unregulated supply able to give 4 amps could well produce 7v or 8v when only lightly loaded. Borrow a voltmeter to check 5v DC. If it is regulated at 5v then a resistor will not be a good way to limit the current. A 5R ...
