Night Vision Toilet




About: Dad and hubby, good food enthusiast, solar energy, boating, making stuff, melting stuff, and raising chickens.

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.

    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.

    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.

    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

    ya thats what i did with a quarter, cut in half with wire cutters. and drilled holes bam necklace. also i flatened and stretched a penny with it for the necklace looks pretty cool i got one n so does my gf

    If thingygoboom really needed the penny that bad, just melt the solder off of it. Think about this, if you are paid minimun wage $5.15/hour, your time value per minute would be 8.5 cents. At minimum wage, I just wasted a can of soda to type out this response over destroying a penny. lol

    lol. who cares. did you know in arkansas, when pulling from a side road into a main road, you are required to pull clear over to the lane closest to the middle and THEN move BACK over to the lane you want to be in. hoiw dumb (and unsafe) is that??? its totaly opposite in other states. I would never follow that law unless there was a cop right there. its totaly unsafe.

    Arizona Law states that it is illegal for a woman to drive unless a man walks fifteen paces in front of her with a lantern. We don't follow that one much though. lol

    If you ever need an endless supply of white LED's just buy or scrounge a led flood light, I got one at COSTCO for something like 15 bucks, the thing has like 50 5mm bulbs in it, I bought one 3 years ago and I haven't used half the LEDs yet.

    Now all you have to do is find a motion sensor from one of those cheep Halloween toys squeeze it in there and you have a hands free light.
