Step 10 One more example

I've used similar technique to modify antique analogue meter for my next project.

It looks goods

Not to quibble but the reason old analogue meters have the reflective strip is so that you can line up your eye with the needle and its reflection and thus avoid erroneous readings caused by the distance between the needle and the scale and the angle at which you look at it. Not that that always matters but I thought it might be an interesting titbit.

Have to admit I never wondered (enough) what the reflective bit was for. Now that I know, it's an elegant solution to an obvious problem. Thanks.

The word you are looking for is
parallax : the apparent displacement or the difference in apparent direction of an object as seen from two different points not on a straight line with the object; (Merriam-Webster)

[Whatnot]

Not quite, although I could have used parallax in the description it would not do on its own and I was deliberately more liberal with words to make it clear anyway. So I wasn't really looking for the word parallax :)

Great instructable! I wish there was a way to make the light reflect more evenly.

I agree. So, more research to conduct. Thanks!
