Hey, youse guys . . . . . . . .
Why don't you try firing up the #2 puppy with a 9V battery and see what happens?
Not exactly what you would expect . . . . since that circuit is dependent upon a static /hi Z AC coupled "ground" thru the power adapter. INSTEAD of the use of a a solo independent / isolated / floating 9 V (or 12) batttery.
When you finger touch the two electrodes induced 60~ hum / pulses picked up from house wiring into your body and outted thru a fingertip is triggering the 555 I.C. latch function working in conjunction with the static AC circuit return. .
. . . . . . .some LEDs will light properly
Now I can't examine and evaluate the RED LED, for why it is not functioning.
But just look at the 6 other operating LEDS and you can easily see the two WHITE ones light brightly.
While the 4 other ERSATZ GREENS AND BLUES are not actually being bonafide R & G electro chemically constructed units.
Instead, they are ALSO being WHITE units that are then depending upon a tinting of their outer mold casting for the coloring aspect . . . . . . but, then performing quite dismally, in that respect..
My wife would be thrilled with this rinky dinky bottle cap construction as a gift ? ? ? ? . . . . . . possibly back when she was 4.
