The GIZMOS "Star Master" LED Star Projector (hereinater probably just called the Star Master) is an LED-based mood lamp that projects a colorful "starfield" on your walls and ceiling.
The Star Master operates from 3 AA cells or from a 4.50 volts DC adapter -- neither of which are furnished.
It has three operating modes (not including "off"):
1: Color-shifting stars
2: Warm white stars
3: Combination of color-shifting and warm white stars
SIZE
Feed the Star Master three AA cells first (see directly below) or plug it up to a 4.5 volts DC adapter and THEN you can project some colorful "stars" in your room.
Press and release the button labelled, "STAR" on the lower edge of the side of the Star Master to turn the warm white LED on and project numerous (hundreds) of warm white "stars" on your walls and ceiling.
Press and release the same button again to neutralise the Star Master.
Press and release the button labelled, "LED" on the lower edge of the side of the Star Master (on the opposite side of the "STAR" button) to turn the red, green, and blue LEDs on and project numerous (hundreds) of colored "stars" on your walls and ceiling.
Press and release the same button again to neutralise the Star Master.
Press and release the buttons labelled, "LED" and, "STAR" on the lower edge of the side of the Star Master to turn both the warm white and the red, green, and blue LEDs on and project numerous (hundreds) of warm white and colored "stars" on your walls and ceiling.
Press and release the same buttons again to neutralise the Star Master.
To change the batteries in the Star Master, turn the unit upside-down. You'll see a battery door. Unclip and remove it, carry it to the basement stairs, and huck it down into the basement with all of the hungry carpenter ants that need to have a wee so that the little insects start to nibble on it, find it unpalatable, and squat and go poddy on it...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.
If necessary, remove and dispose of, recharge, or recycle the tired AA cells from the battery compartment.
Insert three new AA cells into the chambers, oriening them so that their flat-ends (-) negatives face the springs for them in each compartment.
Finally, reinstall the battery door.
Aren't you glad that you didn't chuck that battery door into the basement with all of those carpenter ants that had to piss?
Current usage measures 300mA (white LED), 275mA (colored LEDs) and 510mA (all LEDs) on my DMM's 10A scale.
The Star Master is a mood light strictly-dictly for use indoors, not a flashlight meant to be bashed, thrashed, trashed, and abused.
So if you were hoping to see me perform, "The Smack Test" or, "The Toliet Test" on it, you're going to be a bit dissapointed.
Because the absusive tests will not be performed on this product, this part of the web page will appear a bit more bare than this part of the page about a flashlight.
