Re: Can you power the Pi from GPIO?

Allan/Gert,

Thinking about it, why would the 3v3 regulator have issues as it wouldn't have 5v on its input side?  I only intended supplying 3v3 - or are you suggesting the 5V would come in on the output USB from the powered hub?

Re: Can you power the Pi from GPIO?

<r>Thanks for that Gert, I suspected it wouldn't be quite so simple - back to a separate voltage regulator (<URL url="http://www.maplin.co.uk/1a-low.....ator-46321">http://www.maplin.co.uk/1a-low.....ator-46321</URL>) ) off the 6V or 12V rails and two smoothing Caps I can rob off the Humax mainboard...

Re: Can you power the Pi from GPIO?

<t>As a separate question, can I power the processing side of the RasPi from the 3v3 pin on the GPIO?  I am aware that the power side of USB wouldn't work (but would the comms side?) however, if I can find a 12V or 6V input powered hub I already have a power supply in a dead (tuner not working) Huma...

here are 2 small heavy duty cases that should work , and they are supposed to be waterproof 

Waterproof only so long as you don't want to connect any external wires, cables or PSU!

Re: Setting up a usb gps dongle

<t>GPS time are the seconds since 00:00:00 on 1st January 1970 so the UTC of  1326279176.68 when you executed the query to your GPS unit works out as 10:52:57 on 11/01/2012.<br/> <br/> I don't know how to work out the date exactly but there is probably a python script which can do it for you (I just...
