[Lab] USB_IR_Toy_v2

[siggen]

Nice gadget!

The circuit ought to work with two IR emitters wired in series in place 
of the single one on the board: --->|---->|---   (Three in series might 
work, but the available voltage is marginal.)

An external copy of the driver (R5, D2, D3, T1, R4) would support an 
additional IR emitter or two. None of the part numbers of the 
semiconductors in the driver are critical.
