Probably I can't afford long distance transfers.
Yup that's going to be the problem I have several things which would be nice in that environment - but.... -> and having worked in a museum as a display tech -> best wishes with the project.....
I once had to give a lecture to university students on PC hardware because the HoD thought they hadn't a clue (he didn't need his professorship to work that out). We borrowed a bunch of bits and pieces from Tech Services and laid them out in a form that gave them "relationship" as in "zones" inside a tower box -> also dismantled HDDs and so on -> then, we boggled their minds with the simplicity of binary vs octal vs decimal vs hexadecimal, and, the question: 1 + 1 = 10.. They could do 9 + 1 = 10 (well some of them) -> they couldn't understand things they had learned in primary school, like, you only have 10 digits 0 through 9 and then you have a 1's column a 10's column a 100's column etc -> add 9 + 1 what do you do? They were lost. Put a zero then a one to the left of it (No?). You know where this going..... in binary - only two digits 0 and 1 -> add 1 + 1 what do you do?
OK (we were rolling below the whiteboard at this stage)
As to BITS BYTES WORDS NYBBLES RAM ROM how stuff is stored multiplication and division (or as we know it adding and subtracting)
DON'T even ask what happened when we tried the same principles on HEXADECIMAL
Just an idea or two for you to contemplate as displays or even B4X/a/j apps as interactive bits for a museum format display. Be nice B4J exercise setting up some of that sort of thing.....for interactive stations and self-learning exercises.......
Might go well with those books you authored.........
