Algodoo

Nice work.

I recall my first experience with a slide rule was back in the Stone Age when I learned how to multiply by adding logs (not the wooden kind). Then when calculators became affordable I repurposed my slide rule as a back scratcher (and not a very good one).

I found that vinodril's slide rule moves more like a real one by increasing the air friction, and the air friction multiplier for the slide and for the cursor. With the right values of air friction, those components no longer act like skates sliding across an ice rink. I also increased the pull force of the drag tool which helped.

I started my engineering education with logtable. Slide Rule was introduced in II year of engineering. A made in Germany "Aristo" brand was most popular in India at that time. When I was in final year of engineering I saw first calculater by HP. It was bright green led display.

I see that you, Xray, and I are all old timers.

P.S. I see that you are a Mechanical Engineer. Check out Algodoo for Engineering.

Where does it say I'm an M.E? All I see on that page are technical engineering type scenes that were made by YOU. (BTW - No I am not an M.E. Most of my professional work has been developing digital circuits for embedded 8-bit computer boards in industrial and medical equipment. So, my expertise is electronics design and 8-bit assembler code for the Intel 8085 uP back in the 1980's and 1990's). Yes I am an "old timer".

Q: Where does it say I'm an M.E?
A: Nowhere. I was responding to vinodrai. Are you making a joke because the response is open to interpretation?

Q: All I see on that page are technical engineering type scenes that were made by YOU.
A: Yes. I can see that I am very popular on that web site.

Okay, I see what cause my confusion. In the first sentence of your comment you addressed me: "I see that you, Xray, and I are all old timers." Then in the very next sentence it appeared that you were still addressing me with a PS: "P.S. I see that you are a Mechanical Engineer. Check out Algodoo for Engineering." Now I know you were addressing vinodrai. It's ambiguous. Just a bit more than an old-timer can handle. LOL
