1) I would buy something else instead of the Lego device for $30. The
Lego mindstorm transmitter requires a battery.
At work we have several of these JetEye serial transcievers that work well.
I bought 2 of these JetEye's from this seller and am quite happy with the
transaction and the devices. See below.
2) I am also very interested in how to use the lego IR Tower transmitter.
I have one of these at home and would like to play with it.
