What is Karma (17 Oct 2019)

Karma is one way to say "thank you" to a poster that was of particular good help to you on your posted question or problem. It's OPTIONAL and avoids cluttering up forum posts with many "Thank you's". You can also personally Thank the poster and show that they have helped you by clicking on "Thank you". The higher your karma value and the number of "Thank you's" is a fun measure of your value and status about TecHKnow. You can increase (or decrease) a persons' Karam by clicking on the "more" icon just below their user Picture/Avatar

Either battery pack, voltmeter (in parallel), ammeter(in series) and heat/cool the unit with a hairdrier, a hand, an ice cube or whatever. Or just use a multimeter on ohms range and heat/cool accordingly.

Stick it to a multimeter on resistance so they can see what happens.
They find the V - A meters faffy.

After that stick it in a potential divider to make it 'control' something. E.g. an LED on/off
If you need help with that, the Resistance at room temperature needs to be known.
