I have the | oscillator running in a small cast aluminum box and my idea was to bolt | a power transistor to the case and use that as the variable heating | element. I would then mount the whole unit inside a block of foam | insulation. I would like to hold the crystal at a non critical | temperature between 35-50C. Any ideas? | cheers | -- | | ===================================================================== | Lawrence Glaister VE7IT mailto:lg@jfm.bc.ca | 1462 Madrona Drive http://jfm.bc.ca/ | Nanoose Bay, B.C. http://members.home.com/cncstuff | Canada V9P 9C9 http://gspy.sourceforge.net | ===================================================================== | | -- | http://www.piclist.com hint: To leave the PICList | mailto:piclist-unsubscribe-request@mitvma.mit.edu | | -- | http://www.piclist.com#nomail Going offline?
