Bulbs in parallel - test-drb@ccmp.vtda.org

4 Jan 1999

Sorry this is so late. I just don't do email when I'm at home.
And so over Christmas a lot of email piled up and I'm way behind
in my reading. If this question has been answered, well I havn't 
gotten that far yet in my reading.

 OK, now I have the feeling I may have forgotten
something. When you wire
some bulbs in series, and one burns out, they all fail. If they are wired
in ||, and one burns out, the others keep burning. What more is there? 
OK, what would you say if I told you that you could build a two input AND
gate or a two input OR gate using just two neon bulbs (in parallel), one
resistor AND NO TRANSISTORS?
 Or, how about a one bit readable, writable memory circuit consisting of
one neon bulb, two resistors, and a capacitor?
 How about a ring counter with no ICs, no transistors?
 I put some scanned pages up on my web page so you could grab them. The 
.ZIP file consists of 11 .GIF files. Each file represents two pages.
So lamp4546.gif (pages 45 and 46) is the first two pages and lamp6566.gif
is the last two pages.
 The zip file is at http://www.best.com/~dcoward/lamp.zip

 If you can't view .GIF files offline, then just bring up each file with
your browser. Start with http://www.best.com/~dcoward/lamp4546.gif

I'll leave the files up for at least a week.
I hope this rekindles your interest in lamp circuits.
