Step 3Still working on it. Schematic!
Now making the schematic and putting it here.
Notes:
1.Notice that pins 2 and 6 are connected together under or over the IC.
2.An additional pot, perhaps 1K, can be put in series with the LEDs,
because changing the brightness has noticeable effects.
3.A headphone cord can be used to connect glasses LEDs to circuit box.
Obviously the glasses might not be in the circuit box so the connection points are marked with X.
4.You can obviously use a wallwart instead of a battery if you're not all wet.
5.At this point I have not decided whether to add more LEDs
or which side of the sun glasses works better.
Translucentifying the lenses and putting the LEDs outside may permit use with eyes open,
if it works well that way.
6.If the 10K knob turning clockwise slows down the flash speed, reverse it's wires if you want.
7.Although the LEDs are shown inside the schematic, I am running wires outside the unit
to the LEDs on the glasses.
8. The Anti-Idiot Diode prevents damage from reversing the polarity as long as the idiot didn't
install the diode backwards. Any cheap diode may be used.
9. The CMOS version of the 555 is ok to use and probably even better.
10. Sorry for the messy schematic. It looks more complicated than it is.
UH OH - BIG OOPS! THE 1UF CAPACITOR SHOULD BE 10uF!!!!!!
The 1uF capacitor will not work!
