I've only been able to get about 1 night out of a 9v batter so far.
I may have to slow down the blink rate...
Thinking about cascading 556's.

(2) 100 ohm resistors 1/4w
(2) 22k ohm resistors 1/4w
(2) 330k ohm resistors 1/4w
(4) Red LED
LM556 Dual TimerQty
22uf Capacitor 16v+
33uf Capaticor 16v+
9v Battery Clip
Double Sided Foam Tape
3' Solid Core Wire Pair (I stripped some ethernet cable)
First, a couple of assemblies from the parts list
are going to make things go a lot faster:
2) Twisted 22k and 330k resistor.
The 22k (red red orange) should be soldered to pin 14.
It's best to apply a bit of solder to each pin, and then heat the pin.
I solder the white part to positive and dark part to the resistor.
7) Hide a couple sets in some very dark bushes.
