[mythtv] OT: Question about IR Blaster Circuit

I've got a question about building the IR circuits.

I am no electronics wizz, so I showed the circuit layouts to my friend.  I
showed him the IR receiver from http://www.lirc.org/images/schematics.gif
and the IR transmitter from http://www.blars.org/blarslirc/.  He noticed
that the receive diagram uses pin 5 for ground, but the transmit diagram
seems to use pin 5 for power (?).  Again, I couldn't solder my way out of
a paper bag, so I was wondering if anyone can make sense out of the two
diagrams.

If the pin-outs for the transmit circuit are incorrect, what _should_ they
be?


Thanks!
Jeremy
