[Lab] USB_IR_Toy_v2

[Bennett Kanuka]

Paul, Thanks for the help!  I'm glad I can focus only on the driver part of
the diagram.  I think making an external copy is the way to go.  My goal is
to get the IR as bright as possible.
I think with the limitations of being powered through USB mean that at most
I can power about 5 (?) LEDs: 1 built in and a cluster of 4 on an external
driver.  So my guess is that I can  wire 4 IR leds together (in what
configuration - I'm not sure) and then lower or completely remove R4.  I'm
not sure then what changes are needed for T1 or C8.

Regardless, I'll come to the meetup on the 17th (with the parts).  Looking
forward to meeting some of you!
