I have this (http://www.ghielectronics.com/catalog/product/253) (along with the receiver).
(also using the Fez Panda 2)
I have tested the receiver with a TV remote and get a great distance of several meters and the receiver still picks up the remote.
But using the IR Transmitter Eblock I only get 4-6 inches. I am using a component shield also, have the eblock pluged into a digital port on there.
Should I get better distance than 4 inches?
