For those who remember Blondie in their hey-day, many will also remember the Man-from-Mars flashing red eyes behind RayBan sunglasses in the "Rapture" music clip.

Below are two shots lifted from the clip on youtube, one of the "Man from Mars" and the other Clem Bourke, the drummer. I have highlighted the flashing eyes (and intend to replace these shots with full-res shots taken from my own DVD when I get back home).


For the Sydney concert on Thursday 2012-12-06, I decided (at the last minute) to make my own version of the glasses that would attract attention during the song "Rapture".

For something just to look weird walking down the street, two high-bright leds operated by a hidden flashing led would suffice, but when one wants to be seen against the intensity of stage lighting something stronger would be required. I also decided on Green instead of Red, because:

1. The brightest green LEDs I could get were 64.4 Candle;
2. The brightest red LEDs I could get were only abut 24 Candle;
3. Even at equal brightness, the Green will cut through whereas the Red would be lost.

This instructable has many photos and "micro" steps as I was still learning to use the new camera intended for the concert (I got 144 photos!). I will also discuss other options that were considered along the way.

Step 1: The control circuit

This is the only decent shot of the circuit board, as it was a kit. As instructions come with kits, I see no point in duplicating them here.

As I was only using LEDs, I would have preferred to use a standard "multi-vibrator" circuit that has two transistors, however, time did not allow the luxury of going through catalogs locating the correct value parts, and among the kits available there was only this Alarm Dasher Flasher which, because it is part of an educational series, is based on a 555 timer.

As this circuit would handle anything from 6V to 24V, I seriously considered replacing the power Transistor with a 4A version to run genuine colored brake-lights. I dismissed this idea due to heat--I didn't fancy burning my eye-lids. So, I ended up with a nuclear power plant being used to boil an egg.

As I was still considering the use of real light bulbs the use of an 8 * AA carrier was compulsory, and I already had the AA cells.

If I had never considered light bulbs, a single 9V battery could have resulted in a much smaller box. The circuit board is held in position with "BluTack".

The width of the box was convenient for the battery-pack, and the rubber bands around it stop the pack from sliding in either direction. By centering it, the box is more balanced than if all the AA cells were placed at one end.
dude you look like jack black!
You're not the first person to suggest the similarity.
Looking good - how well could you see out of them?
Because they were arranged by line-of-sight direct vision was impaired but, peripheral vision was excellent. I still wouldn't try waving down a bus...
