For those who missed the last puzzle, what is this?

  1. It looks like netting for a chair or something… I think you could sit on whatever it is and it would hold you.

  2. Looks like core memory. an array of doughnut-shaped magnets which are read and written via the intersections of the grid of electrical wires running through them.

  3. Mesh over the air vent on a classic car or some other contraption?

  4. Bingo to ScottyM, and within one hour no less!

    Thirty years ago, this was the standard for memory in electronics. The core memory boards were hand woven at first (this photo was from a board with the largest cores I have seen… an early model). Over time, the cores became smaller, more tightly packed, and machine woven. I just posted an example of that.

    The next puzzle will have to be tougher!

  5. Bravo! beam us up Scotty

  6. nice. love this ‘gadget guts’ series!!

  7. So, wait, the crossing wires never touch? So the magnetism at the intersections captures the value? How bizarre! I never got around to looking into how core memory worked!

  8. So, wait, the crossing wires never touch?

    The wires are likely coated in enamel so the conductors can’t touch. However, the magnetic fields created by currents in the wires are not stopped by the enamel and can interact with the iron cores.

  9. Ah, yes, the solenoid winder’s dream, just don’t scratch the enamel.

  10. Great shot. Makes me think of a static abacus: long-ago ancestor to the electronics.

  11. maybe a ‘One Ring’ factory, souvnir of the Dark ages….mmm, guess this is the geek in me talking 🙂

  12. Dang it. and I knew this one too.

    Day late, dollar short.

  13. Actually, ScottyM is only partially correct. The rings are not magnets, they are ferrite disks.

  14. Great Work.. Informative as well as Entertaining..

  15. Congratulations! This photo won 1st place in the contest Woven
