Q: Is there a circuit which can multiply the resistance value?

Rajamy sensor gives a reading in resistance change. However, I can track that change easily with an amplifier circuit. However, I don't want to use in that way.

Hmm, I'll offer a different view here: The new font looks better than the old one (at least on Windows). I seem to like fonts with letters that are more "geometric" (I like the Twentieth Century font for the same reason).

But again, that's my own perspective

Q: Policy on closing old questions

NathanielI posted a question back in 2016. As an open-ended challenge it was on topic at the time, and now it's not, which is fine. Now the question has been closed, which is also no problem for me. The question is, was closing it now really necessary? The question had no activity for years and I've barel...
