Can someone inform me wether the following device could be used as an IR Transmitter via Lirc ? I picked up one of these at a yard sale for 10$ hoping I can use it to change channels on my digital cable receiver using Lirc.

and if not, does anyone have specs for a IR Transmitting device that can be assembled from parts obtainable at radio shack ?
 
thanks,
Nick.
