The Rainbiow-In-Motion Astro Strobe is a novelty keychain device that looks like it emits white light when it is placed on a hard surface and then stared at; but explodes into a rainbow of colors like electric Skittles when it is waved about or when your eyes move.

It has three AG3 (LR41) button cells in its body, and has three chip-type LEDs that flash in a sequential pattern to provide those explosive color effects.


This product is ready to use as soon as you remove it from the package. Cut down one side of the package with a razor blade, a knife, or a pair of household scissors; and remove the unit.

Grasp the metal base with one hand, grasp the part with the stars & moons cutouts with the other, and apply a firm but gentle clockwise twisting motion. This turns it on.

Do the same thing, except twist counterclockwise, to turn the unit back off.

Keys can be affixed to it by means of a medium-sized split ring, or it can easily be affixed to an existing keychain by means of a spring-loaded "lobster claw" clasp.
These keychain accessories are on a swivel, so you cannot get this device tangled up.

To change the batteries, turn the unit upside-down, and unscrew the product until the tailcap comes off. Set the tailcap aside.

Tip the three used AG3 (LR41) cells out of the body you're still holding into your hand, and recycle or dispose of them as you see fit. Be sure the little black O-ring that *MAY* be on the first cell does not fall off and become lost or end up in the garbage can, vacume cleaner bag, or battery reclamation box.

Stack three AG3 or LR41 button cells on a table, counter, or desk on top of one another, so their flat-ends (+) positives face down.

Lower the barrel of the unit directly over them. Then you can either pinch your thumb & forefinger around the bottom as you lift and flip it over (so the batteries don't fall right out), or slide a business card underneath, and then lift the barrel & card at the same time and flip it over.

Then just screw the tailcap back on firmly.
If you had the little O-ring come out, lay it on top of that last cell before you screw the tailcap back on.

Current usage measures 12.49mA on my DMM's 400mA scale.

This product appears to be at least somewhat splatter-resistant, but I do not for one second believe it is submersible. So water, milk, diet Pepsi, coffee, urine, root beer, or other liquids could get inside. So please try not to drop it in creeks, rivers, ponds, lakes, oceansides, docksides, puddles of polar bear urination, glasses of milk, slush piles, mud puddles, tubs, root beer floats, toilet bowls, cisterns, sinks, cups of coffee, fishtanks, dog water dishes, old yucky wet mops, or other places where water or water-like liquids might be found.
And for Pete sakes, do not place it in a wall-mounted porcelain urinator and pee on it.
A little rain or snow probably wouldn't hurt it though, so you need not be too concerned about using it in lightly to possibly moderately bad weather.

If it fell in water and you suspect it got flooded, disassemble it as you would for a battery change, dump out the water if necessary, and set the parts in a warm dry place for a day or so just to be sure it's completely dry inside before you reassemble and use it again.

If it fell into seawater, got thrown into a glass of milk, or if somebody or something peed on it, douche all the parts out with fresh water before setting them out to dry. You don't want your Astro Strobe to smell like seaweed, milk, or piss when you go to use it next. Besides, salt (from seawater or urine), lactic acid (from moo juice), or sugar (from root beer & ice cream) can't be very good for the insides.

Both test units of the Rainbow-In-Motion Asstro Strobe were purchased at the Greenwood Friendly Food Mart in Seattle on 01-15-06 and 02-14-06. Both units were defective; however I narrowed the problem down to the batteries themselves, and after replacing them with the batteries from the Crystal LED Glow Keychain, the product functioned - as best I can determine - as intended.

Product was made in China. A product's country of origin really does matter to some people, which is why I published it on this web page.
