Don't go blind.

Thanks for the trip down memory lane! As soon as I saw the title of the thread, I KNEW it was going to be this. Only time I've ever seen the word "ambihelical". By the way, was this in QST, Pop'tronics or where. I know I first saw it back in high school.

Now, just because of the memory jog, I'm going to Google the word. Pretty sure I'll be deluged, but ...

Thanks again!

Brings me back to the Mechanical Drawing tricks in high school. I wish I could remember them all, but those days are all a blurr now.

I remember the 3 legged thing from a MAD Magazine back in the late 50's or early 60's

I remember the 3 legged thing from a MAD Magazine back in the late 50's or early 60's

It was 1965, and they called it a "POIUYT".
