Step 7Breadboard Schematic
For a few hours this looked ridiculous without the schematic.
It's a rough one, still being checked at this time.
Check back every once in a while for updates.
Teaser: Gray Code enumeration: It moves along the edge of a cube of
dimensions equal in number to the number of bits. To bend this into
gray code without programming, you would need 32 XOR gates.
Perhaps you would prefer the PIC code, as in the original P-Box...
This has too many wires!
QUICK BENDS:
If you build this and get tired of how it sounds, I recommend mixing up the
"blue" wires on the 4040 next to the 555.
The 4051 wire order isn't as noticeably significant.
Removing one or two "green" wires from the last 4051 maybe interesting,
which I did backwards by building the circuit with power on it.
And of course, turn the playing speed knob.
The "green" wire on the left 4040 pin 1 is a reset trigger that "never" resets.
So move that reset wire to other pins and expect major changes in the sound.
I'm concerned about the 555 going too slow, but IF that happens
(making only low pitched sounds at all speeds)
try changing the 555's capacitor from 1nF (0.001uF) to 100pF.
The 555 was not tested in the circuit, I used a 4060 instead.
It will work though. Like in my hypnosis glasses instructable.
One advantage of this no-brain "mess" circuit is the convenient bending possibilities.
The following is the last sound I created on a PC immediately before that PC was
wedged in the keyboard (remote controlled) by an illegal DRM hack and rendered
useless, and is the first STEREO one generated by a process which could be
emulated by a circuit with 4 times as many of these chips; and although the
sound is open-ended (cut off at the end), it shows more synth-like qualities
than many of my other "Music-Ex-Nihilo" (P-Box) experiments.
Last PC generated, First Stereo P-Box sound from 10/2005
It's equivalent to output of a hardware bend, with diagonal orthogonal counting on 3 axis.
It also was done with a 256 bit counter. Remember, the counters are experimental only,
and impractical, since it will take forever to get to any serious music. That sound filled up
my hard drive needlessly, and reached the "convenient" limits of the PC to do this stuff.
(But more chips in the pattern below could have done it!)
A few million bits requires some obscure simple arithmetic (a Pythagorean Mystery)
to make all songs. There is a solution, which I will publish as P-Box #3 when it is made
understandable. Understand this, that THE NUMBER is only the simplest to understand
number that is useful for this purpose. Numbers can be defined for any similarly
special and amazing purpose, and as I mentioned before, the simple obvious
number is not ideal but easy to understand...I HOPE.
This is the schematic drawn from the breadboard on Step 2.
I mentioned before it's limited to 32 bits, unless you add more chips.
Twice as many chips gives 64 bits.
Eight times as many gives 256 bits. If you got the chips, the sky's the limit.
