    You have a wonderful way of explaining these concepts in a very digestible, and intuitive format. Thanks!!

    Glad to see the series continuing. Since the last video I built a ring oscillator using three relay inverters with a 3000 uf capacitor to slow the cycle time to a few ticks per second. I was working on an SR latch to build a counter, but I don't have it quite right yet.

      Cool, it's really fun to see the relays running. I trust you have appropriate blinkenlights connected.
      In this series, I'll be doing a SR flip-flop next, then a ripple counter, then the gates required to restrict it to 60 mins and 12 hours.
      I'm tempted to start on the ALU (based on Deiter Muller's) for the CPU, we've covered enough in this basic series already to make a start on that as well.

      @@DrMattRegan I have some LEDs for the blinker lights. But I am tempted to get lamps like yours as that suits the aesthetic. Looking forward to the next video.

    1:52 - I'm guessing you might be introducing diode-resistor logic to explain how to get wired OR gates to work properly?

    • @DrMattRegan
      @DrMattRegan  5 місяців тому

      No, I’m not planning on using diodes except for fly back, at least for this series. Wired OR gates can be done this way. I will have to say a bit later though about rules for implementing wired OR in the scheduler’s decoder.

    Again, no errors in this video that I could see.
    Ah. The two-relay latch relies on disconnectedness, too. In that case, I guess the reason you still used it rather than the one-relay version is that the two-relay version still uses control logic that maps to what would be used for a zero-volt logic latch, whereas the single-relay version does not.
