"MOUSE" KEYCHAIN
LASER POINTER


"Mouse" Keychain Laser Pointer, retail $TBA
Manufactured by (Unknown)
Last updated 07-26-11






What this is is a keychain laser pointer. It emits a red beam (measured spectrographically at 654.450nm) with a measured output power of 1.60mW, and it includes a holographic projection head that projects an image of a mouse. It comes in a handsome chrome-finish body with gold-colored bezel and tailcap.

It was specifically designed to be used as a cat toy; your kitty can chase either a plain dot or a mouse.

It fits on your keychain with either the split-ring or the spring-loaded "lobster claw" attachment, so you can carry it anywhere. And it feeds from two LR44 button cells.

Because this is a laser, you should not shine it into your eyes, other people's eyes, pet's eyes, etc. Just use a little common sense here, ok?


SIZE



To use your new laser pointer, feed it first (see below), and then you'll be ready to drive the kitty cat bats**t.

Press the button on the barrel and hold it down for as long as you want or need the laser beam, and release it to shut the unit back off.
Don't aim the laser at your face when you push the button, otherwise you might hit yourself in the eyes with the laser beam, and that wouldn't be very good at all.
That covers the functioning of the laser pointer itself.

To attach the holographic pattern projection head, unscrew and remove the dome-shaped part at the front of the laser pointer, and set it aside. Screw on the dome-shaped "mouse" projection head, and let the kitty cat chase the little red "mouse" across the room.



This laser pointer requires two LR44 button cells, which are included in the package so you don't need to run to the store right away. To change them, unscrew and remove the tailpiece, throw it in the litterbox, and use the "pooper scooper" to bury it...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.

Tip the open end of the laser pointer into your hand, and dispose of or recycle the two button cells that come out as you see fit.

Stack two new LR44 button cells on top of one another on a table, countertop, or other flat surface, button-end (-) negative facing up. Lower the laser pointer over this stack so that both cells are in the barrel.

Slide the assembly to the edge of whatever surface you're reloading the pointer on, and place your finger over the laser pointer's opening as you slide it over the edge, so those batteries don't just clatter to the floor. Invert (flip over) the laser pointer now, so the open end of the barrel faces up. Remove your finger. Screw the tailpiece back on, and be done with it.


Aren't you glad you didn't throw that tailpiece in the plastic cat toliet now?

Current usage measures 24.30mA on my DMM's 40mA scale.



The "Mouse" Keychain Laser Pointer is not water-resistant or submersible, and probably would not withstand being stomped on or run over either. But it should not break just hanging on your keychain.

Since laser pointers like this are not meant to be stomped on, run over, drowned in the commode, or otherwise abused, I will not inflict those sorts of punishments upon this one. This was also borrowed from my sister (who would probably appreciate receiving it back in working order), so this section of the web page will be a bit on the bare side. :-/

The laser pointer emits a red beam measured at 654.450nm in wavelength, and has a measured output power of 1.60mW (with the bezel piece on) and 3.868mW (with the bezel piece off) using a Sper Scientific Pocket Laser Power Meter # 840011 -- so it's "cat eye safe" and it's kosher to use this as a cat toy as it is being sold specifically for this purpose.



The laser pointer's dot by itself, on the target approximately 12" away.
Does not appear white or as large in real life



The laser pointer' "dot" on a wall ~10 feet away.
Again, that white color does not appear in reality.



The laser pointer with the "mouse" head on a wall approximately 5' away.
That yellow color does not appear in reality.





Spectrographic analysis
Spectrographic analysis of this laser.


Spectrographic analysis
Same as above; spectrometer's response narrowed to a range between
645nm and 665nm to pinpoint wavelength, which is in fact 654.450nm.

USB2000 spectrometer graciously donated by P.L.


Normally, beam cross-sectional analyses would be here, but the instrument used for those plus the computer it interfaces with have been packed away for a move to take place in early-September 2011; thus I no longer have them at my disposal.





TEST NOTES:
Test unit belongs to my sister who purchased it (probably at a PetSmart or a Petco) within the last year or so in Federal Way WA. USA to use as a cat toy; it was found in her room on 07-21-11 (or "21 Jul 2011" or even "Jul 21, Twenty Double Sticks" if you prefer) while she was packing some stuff for a very near-future move.

Since it does not belong to me, the somewhat dreadful "" icon will be appended to its listings on this website at once.


UPDATE: 00-00-00



PROS:
Cat-eye safe
Made entirely of metal -- even the holographic projection head
Laser is labelled properly


CONS:
Not very waterproof at all, and *DEFINITELY* not submersible
Projected image of mouse is a bit sub-par
Batteries it requires could be a bit difficult to find or more expensive than necessary in "brick-and-mortar" stores
