#1 LDR's

Post by Paul Barker »

Just found I have a pair of vintage Mullard RPY18

rated at 0.75 watts 200v

Resistance 1Ω to 1MΩ

Nice range, nice power rating.

Might find myself a use in audio for these.

Not expensive

You could connect it to a Peltier device and vary the resistance by temperature. Alternately, a halogen light bulb generates enough heat, it would be kind of like an LDR.
