old toaster acquired

An old man in the neighbourhood had a yard sale today. Looks like he's moving out of his home after many years. I picked up a few items for cheap. And I got a special discount for moving the old washing machine out too!

In particular, I bought an old toaster, a vintage Proctor "colorminder." I'll take the heating element wires from it to build some of my own custom dew heaters. For my binos, SP-C8 finder scope, and Mom's telescope!

§

Extracted three strips of nichrome wire. Two pieces are approx. 51" in length with a total resistance of 9.4 ohms (that's 7 ohms / metre). The centre piece was longer at 95" with 29 ohms resistance (so 12 ohms / metre).

My first project will be to build a custom heater for my Celestron finder scope, to heat the objective and the eyepiece...
