Thermal Sensor
Heat switch that is normally open below 135° F and closes at higher temperature. Imagination is the limit here. We don't have formal electrical ratings but believe it can handle about 2 Amps @ 120 VAC. It can be used (perhaps with a relay) to trigger a fire alarm when mounted near a furnace, in a garage, or in an attic. How about using it to shut off electronics or motors when overheating occurs? Or to activate a fan for cooling? Use it to record how long the furnace is on to rate its efficiency. 5/8" dia x 3/8" sensor head with (2) 1/4" x 1-5/8" long fixed leads.

LCDs
These liquid crystal displays are raring to go. As soon as we can get Mary Ann to stop playing with them we'll pick out (5) assorted displays for you. (She keeps zapping them with static electricity to see what pops up. Mary Ann is easily amused.) Sizes range from 1-3/16" x 2" to a few as large as 5" x 10". They're unused. Some have pin leads, some have traces right on the wafer. Either way, they're a terrific bargain.

Rechargeable NiMH
While this rechargeable NiMH battery (Mfr Part #B620) fits (31) different Bell South cordless phones, we like it for its battery potential. Shaped like the Superman emblem (1-5/8" tall x 2" wide at its widest x 7/16" thick) the battery has a 2-1/4" lead and a 6mm-wide 2-pin connector, and puts out 3.6V 280mAH. Inside it you'll find (3) 2/3 "AAA" batteries. The 1-1/8" x 3/8" dia cells have flat-tops.
