"Expansion boards (shields)"

It might be a good idea to find an alternative name for R-Pi expansion boards as "shield" brings a lot of preconceived notions ( size, format, pinout ) from the Arduino world which is not applicable to the R-Pi.

<t>Gert said: There are numerous posts about battery operation. Just want to mention here (again) the following: Beware that the boards as they come from the factor are price optimized not power optimized. You will get lower poser consumption if you replace the 1V8 regulator with a...

Unix uses Carriage Return only, while DOD uses Carriage Return and Linefeed.
To be pedantic; doesn't *nix use linefeed (0x0A) ?

How much power is sent down an video RCA port?
Note sure that can really be expressed in any meaningful or useful way but CVBS is usually around 1V p-p into 75R so that's approximately 13mA max, and 1V * 13mA = 13mW.

<t>tufty said: It seems that even the BASIC fans are coming around to the idea that BASIC simply isn"t good enough as it stands, and could bear some improvement. In the sense of K&R C being superseded and C++ being a development upon C and other languages' evolution then it can ...

<t>Abishur said: The good news is that, as was previously mentioned, there is voltage protection on the board and it was designed with this very scenario in mind. Also, the USB would not receive too high a voltage as it is behind the voltage protection, so no worries the...

<t>bf4ed said: Just add LM7805 before power input of r-pi. For use in car or home its wise to add some voltage stabilizer, just bo be on the safe side. Then you can use a cheap ebay supply. The problem is that people buying a supply marked 5V and suitable for...

<t>Frank Buss said: You could even short all output connections and the expander board survives it. Watch out for the maximum draw of the 3V3 rail though; just 50mA. With 680R that's just shy of 5mA per output ( good enough as you say for most LED's ), but 16 output...

<t>Davespice said: Off the top of my head I would guess that when you boot the Pi up with the Composite connector in use the display would adjust accordingly. Composite out is purely "output only" so the R-Pi would have no means to determine what is connected. It w...
