11:29:20 From Jon U. Bell : Sorry for late arrival - Jon Bell, Hallstrom Planetarium, Indian River State College, Fort Pierce, Florida

11:32:04 From Joe Witte : Love the home-made creativity

11:38:00 From Richard McColman : I did some searching online yesterday and did run across French's web page featuring his homemade pointer. I didn't copy the URL, but it's still available online somewhere.

11:39:12 From Todd Ullery : bouncing makes me think there is something between the origin and destination you want me to notice.

11:41:52 From Bill - Sudekum Planetarium : I've actually been tinkering with laser pointers for years. Currently working on a way to incorperate a dimmer as a mini-slider (potentiometer) that slightly varies the voltage to the diode. Usually just using the "dot" - but also adding an arrow.

11:42:14 From Carole Holmberg, Museum of York County : I introduce the pointer by saying "red laser pointers, more than just for entertaining cats"

11:47:42 From Jon U. Bell : The Ash laser arrow size can be adjusted by rotating the front barrel...

11:50:42 From Richard McColman : Try surplus shed online for lenses. <surplusshed.com>
