[TriEmbed] Question concerning a mechanical release

[Scott Hall]

You're going to find solenoids at almost every electronics reseller.  I would
start with these:

All Electronics:
http://www.allelectronics.com/make-a-store/category/575/Solenoids/1.html

Jameco:
http://www.jameco.com/webapp/wcs/stores/servlet/StoreCatalogDrillDownView?langId=-1&storeId=10001&catalogId=10001&search_type=jamecoall&freeText=solenoids

MCM Electronics:

Newark, Allied, Grainger they all have them.  I'm sure some of the TAR folks
could chime in with robotics parts resellers as well.
