I took a pair of sunglasses akin to the ones on the first Terminator movie and mounted two surface mount red L.E.D.s with "Krazy Glue(t.m.)" and wired them up to a small pushbutton switch and two 3v Lithium batteries.
that is all that is needed except one 1/4 watt resistor.
Each red L.E.D. drops 1.8V (typical of most red L.E.D.s) Running both of them in series, they drop 3.6 volts (Vf).
Using Ohm's Law ( V = I x R / I = V divided by R / R = V divided by I)
V = volts...I = current (in amps)... R = resistance in Ohms.
Starting with the 6 volts, (two 3V Lithiums in series) and a pair of L.E.D.s that drop 3.6 volts together and I want to run them around 18 milliiamps. 6V minus the 3.6V leaves 2.4 volts left for the resistor.
I chose a 150 Ohm resistor....So, 2.4 Volts divided by 150 Ohms (V divided by R gives circuit current as stated above) leaves .016 amps (or 16 milliamps) of current through the L.E.D.s making a nice Terminator look to an otherwise "normal" pair of sunglasses.
I mounted the Button (or coin) cell holders above the glasses frame on either side and used magnet wire (coil wrapping wire) to wire everything up.
I wish I could post pics, but as you can see is very easy to construct and very hidious looking.
By using such small L.E.D.s and wire, I can see through the glasses like the L.E.D.s and wire aren't even there, even when they are on, only a minimal amount of red light is seen in your own eyes since the L.E.D.'s reflectors project most of the light forward.
I bought the L.E.D.s from Electronics Goldmine (got 100 of them for about 4 bucks). You can look them up on the 'Net, they have a website.
When I first joined, Gold Cylon said he was looking forward to how I could contribute to others building Cylons since I am an Electronics Engineer. I havn't built anything Cylon yet, but this is something I have built that I wanted to share details about.
I scared my cousin so bad that he jumped about 3 feet in the air when he was coming back up out of the field from a fishing trip, and I hid behind some junk at the top of the hill by the gate that leads out.
When he got out of the truck to open the gate, I made an aweful screaming sound and ran towards him, the result was fantastic!!!!
I cant imagine what I would do if something with red glowing eyes came running at me in pitch black darkness.
Good luck building this and scaring the "Pogees" out of your friends...and.. have a Cylon Haloween!!!!
