Night Vision Toilet





Introduction: Night Vision Toilet

I hate turning on lights at night just to go to the bathroom. When I do it hurts my eyes, wakes up the babies, and I lose my night sight once the light is out and stub my toe. If I just walk in the dark I can see fine until I need to aim for something like the toilet. Here is an easy gravity switched LED that sticks to the lid and doesn't put out too much light but just enough for that 2-am run.

Need to salvage an 3V LED from a happy meal toy or something.
2 plastic soda bottle tops.
A 3V button cell battery, CR2032
A penny
A paper clip
Some double-sided foam tape.

And some solder.

Step 1: Cut Tops of Soda Bottles

Cut the caps of two bottles, make one slice very thin, the other about half way.

Step 2: Solder the Setup

Solder the LED cathode ("-" side of LED) to the penny.
Then bend the anode sideways and solder on a little .25" piece of paper clip.

Step 3: Assemble and Glue Cap

Melt or drill a hole the size of the LED in the thicker bottle cap. (Aim it diagonally towards the bowl, not straight down like in my video and pictures.)

Mount the penny rig into the cap.

Then place the battery into the cap "-" side down; tilt it around and make adjustments based on how the battery contacts things. When you tilt it toward the LED, the battery should slid and make the "+" connection on the paper clip.

Take the thin cap slice and super glue it onto the base. You may need to file the cap cuts to make the pieces fit together better.

Tape it to the toilet lid and wait for the night.

    Well done and very useful. But no one thought that destroying your penny is illegal in the states... well who really cares.

    it isn't illegal if you don't try to spend the penny. Don't you know anything?

    actually, having the penny in your possession means that you own the penny and are able to do whatever you want with it. as far as the government is concerned, it's your property. that's why you can find coins w/ holes in them for necklaces, etc in souvenir shops.

    Isn't there some law saying that "All legal tender is property of the U.S. Government"?

    No, you own it and can do with it as you please. The government just recognizes it as a representation of value. At one time, the government promised that every penny was worth a certain amount of gold. Now, the government just guarantees that people recognize the physical object as worth a certain amount of money. You own a thing that is recognized as having a certain value and can trade it for other things that are supposed to have an equal value. (1 gallon of gas = 400 pennies, for example). It's yours and if you choose to drill a hole in it or flatten it or use it in your night vision toilet project, you're free to do so. once you alter it, the government says it isn't worth anything, but they won't stop you from altering it. heck, it would help curb inflation if more people bent coins and burned bills.

    Oh. Thanks for the info, it's good the know that some people know their stuff!

    Then how is burning money illegal if it's 100% yours?

    It isn't, well, maybe in Thailand (defacing the king,) but other than, generally no, unless you use that bill as legal tender.

    I know this is an old thread, but I thought I should add that it is not illegal in the states to mutilate coins, BUT it is illegal if you are attempting to make them look like a coin of higher value by mutilating them.

    You don't own money, just the value that it has if you know what I mean
