-=== ''Heathkit GR-4000 Projector Television'' ===
-This was a six foot diagonal silver screen projection TV.  It had three large CRTs (Red/Green/Blue).  It was a nightmare to keep the three guns converged.  Every time you turned it on, the set was cold, and it projected three slightly offset images.  You would tweak the geometry with a dozen little knobs, then watch for an hour.  As the set warmed up, the electronics drifted.  You would have to tweak it during the adverts!
-The projector was a big wooden box that sat in the middle of the room, about 2 meters away from the screen.  If the lights were dim, and you didn't look too closely, you'd think you were at the cinema!  All this for only $1800 too.

-I've built a number of interesting antennae.  I'll need to revisit this when I build a video rig for my quadcopter.  I'd like to try a 5GHz skew-planar wheel or cover leaf antennae for this.
