LM7805 12V to 5V?
Quote: 17.5W heat losses means you need a big fat heatsink. And no extra radiators for winter :)

LM7805 12V to 5V?
Yes, you can use an external power transistor to get more current out of it - there should be application notes for it, or at least schematics for it all over the interwebs. And...

I2C and SPI on ATTINY85 in same application.
Uhm... if they share pins, it's going to be a bit tricky on the physical side. Code-wise, as long as you're not doing it at the same time, it should work just fine (re-configuring...

N-MOS and P-MOS TO-92 Part Numbers???
I did a quick search on Farnell, and finding the combo TO-92 and that low RDSon seems impossible. However, if you're willing to accept the TO-220 package, there are numerous...

STK600 : Short circuit or too much current with Leds...
Well, a USB port isn't required to supply more than 100 mA, and will only supply 500 mA after enumeration of the device (basicly, the device asking the PC for more current). If...
