12 IN 1 LASER POINTER

12 in 1 Laser Pointer, retail 99¢
Manufactured by (Unknown)
Last updated 09-27-10




This is a unique little laser pointer with 12 built-in holographic projection films, and two LEDs that flash alternately on a transparent "UFO"-shaped dial - the dial you use to change the projected image.

It comes in a yellow plastic body, and has a short chain with medium-small split-ring and spring-loaded "lobster claw" attachment on the end of it.


SIZE



This product comes to ready to use...well, it's supposed to anyway.
See near the bottom of this evaluation to find out why this might not be so.

Press & hold down the button on the top of the unit to activate the laser and the flashing LEDs.
Release the button to turn it off.

To change the laser beam's projected image, just spin the transparent, water-clear wheel while holding the button down and aiming the laser at a white wall or other light colored surface. Holding the button down during this prcedure serves two purposes: you can see which image you're getting, and you can tell when you have the projection film properly aligned (you'll get a "noisy" red cloud if the pattern imaging film is grossly misaligned).



To change the batteries in this laser pointer, turn it upside-down, use a #0 phillips screwdriver (the one with the 2.0mm shaft diameter from my set of jeweller's screwdrivers worked well here) to unscrew the screw holding the battery door on, lift the door off, and set it aside.

Remove the three used up old LR1130 button cells from the battery compartment, and dispose of or recycle them as you see fit.

Insert three new LR1130 button cells in the compartment, orienting them so their button-ends (-) negatives face the bottom of the copmpartment. Be certain that last cell goes under that springy metal contact in the battery compartment.

Place the battery door back on, and tighten that screw.

Unable to measure current usage due to how the product was constructed and how it functions (those flashing LEDs).

When reassembling the product after just one battery change, the screw became stripped - and I didn't even come close to reefing on it.



This is a laser pointer, not a flashlight. So I won't throw it against the wall, stomp on it, try to drown it in the toliet bowl or the cistern, run over it, swing it against the concrete floor of a patio, bash it open to check it for candiosity, fire it from the cannonada (I guess I've been watching the TV program "Viva Piñata" too much again - candiosity is usually checked with a scanner-type device on a platform or a handheld wand), send it to the Daystrom Institute for additional analysis, or inflict upon it punishments that flashlights may have inflicted upon them. I almost never beat, hit, throw, stomp on, or otherwise attempt to destroy lasers or other products which lase, because of their inherent delicacy. Therefore, this section of the laser's web page will seem SIGNIFICANTLY more bare than this section of the web page on a page about a flashlight.

The spectrometer's response band was narrowed to exclude the red laser line
and the broadband fluorescence emission from the product's yellow body.

That shorter red spike is the laser diode itself, and cannot be eliminated.

TEST NOTES:
Test unit was purchased on Ebay on 07-07-07, and was received on the afternoon of 07-18-07.

It came with dead batteries; it cost me $12.90 for three new Energizer #389 cells (at Longs Drugs in Sacramento CA. USA on 07-19-07) so that I could perform this evaluation.
Therefore, this laser cost me a LOT more than the 99¢ I paid for it.

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.
