Great analysis, David!  Wonder who first invented this puzzle?

I do so love it when Excel is used for electonics purposes. However in your case I see it was only a tool to support your insight.

I hope you don't mind if I subvert the thread and point your readers to my blogs on the use of Excel in electronics on Planet Analog. There are at least 4 more to come over the next 6 months. One is due out any day now.

@Antedeluvian - of course I don't mind!  I am also looking forward to more of your articles.   I have a very good book called Excel by Example by a guy called Aubrey Kagan (unfortunately now out of print) which has some very good Excel tricks in it.   I learned a lot from that! :-)

Could that puzzle be used somehow to some sort of practical end or application?

@Zewde: Could that puzzle be used somehow to some sort of practical end or application?

My "knee-jerk" reaction is to say "Almost certainly!" I base this on the fact that I don't recall learning anything that did not eventually come in handy for something or other :-)

@Zwede - as I said, for the uninitiated you could use it as a decimal to binary converter for numbers less than 64.  Just write "32 16 8 4 2 1" and underneath those numbers, write a 1 if your number is on the corresponding card, and 0 if it is not.  Bingo - Binary representation of your number!

I have a binary clock (BCD format) in my office on top of my computer to confuse people.

I'll have to print up a copy of those cards for my own neferious purposes.

Octal representation

You can see how the cards work more easily if you represent the numbers in octal.  But then you'd have a harder time amazing your friends and relatives with your mind-reading ability.

I had those cards. They came as an insert in Dynamite Magazine, a kid's magazine back in the seventies.

Thanks for the memory.

No. I was eight or nine years old at the time and did not know binary math. I recall amazing all the relatives and being stubborn about not telling how it was done because magicians were not allowed to reveal their secrets.

I also have used '"PCB Designer by Niche Software" for years in my classroom. I recently had to upgrade to windows 7 running 64 bit. Now my PCD Designer will not run!!!!! (is 32 bit software) Have you come across a fix for this? I really like to use the software for my young students because everything else out there is too complex. Can you contact me Thank you in advance.
