Night Vision Toilet

Picture of 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.

My $0.02
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
lol yeah, that law is so lame, pennies are too useful to say you cant "deface" them!
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
lmfao hahaha blondes XD
Wait. How long did it take you to type this? 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.

you know what would go good with this my instructable (pee target)
I prefer using the wash tube...

Its a novel idea- could be done as a school project. Ideas only are worth a million dollars- i am going to make one for my grand child

Like so http://www.evilmadscientist.com/article.php/nightlight
some people do this with LED throwies.

Very nice, simple and effective

to conserve energy, attaching a light sensor could be attached, this would stop it from lighting up when the lights are actually on.

Is it a simple add-on? I don't know too much about sensors and circuitry, hence the crude and simple device I've built here.

Cyberguys used to sell a toilet light that sensed if the seat was down. It lit green if the seat was up and red if it was down.
That's cool...

I have two problems with this project. First, I can only image that thing drilling into my back when I NEED to sit down on the toilet. Second, I've found that when it's late at night, sitting to pee is not that big of a deal for guys. No need to aim, no need to even keep the eyes open. As I'm getting a little older now, I'm also finding that the seated position grants more thurough, um, drainage.
Weee! (pardon the intended pun)
This post is fun! OK, First, if you're having drainage problems, you should go get one of those dreaded prostate exams... something isn't working right... second, sometimes a fella's gotta go, and go RIGHT NOW! No time for things like dropping the drawers, turning around, sitting, and peeing... it's unzip, and flood! Third, with even a MINOR hard-on, you'll NEVER get ANYWHERE NEAR "in" while sitting.. you'd be just like that roman peeing statue boy, and get it all over the floor ;-)

To assuage your fears of getting the light in your back, and the similar fears of all the WOMEN that might use said toilet... mount the beastie at the front , under the seat that way, the light shines when both the lid AND seat are up...helping the standing see their mark, and reminding them to put it back down when they're done, which the womenfolk will be grateful for ;-) Also reminds guys to put the lid up in the first place... if you can't see, the seat must be down, so put it up, right?

Of course this works both ways... If the ladies go into the reading room, and there's a dull red glow, they know to put the seat down themselves! No one like trying to sit if they've forgotten to put the seat down.
The solution to getting a hard on is to sit face the other direction, ie, to face the same direction as though you were standing up. there'd be minimal support for your button, and loads of room up front.. it might be a tad bit uncomfortable, but its only for a pee, how long is that? :)
Reminds me of a sign I saw in Germany in a house. Something like "A real man always sits to pee". I can certainly understand the sign in their case - the house was several hundred years old - can you imagine the smell of over 200 years of pee splatter? Ewww. Good suggestion about putting it under the seat instead of the lid.
That would break a manlaw, and ruin the challenge.

I find just the opposite.
i never sit to pee... never

cool man. well done. it's a great beginner project, since i'm a beginner in soldering. here is my version. Also I might find a way to modify it so it can be triggered by a spring. I had no paperclip so I cut and soldered the anode to make that "bridge". I think a small spring that triggers it would be cool. mabey even neodium magnet on one side to keep the device rooted to the toilet.

One thing I'd personally reccomend with this is to use a clear LED (colour of your choice) which are a bit brighter and clearer, and if you know how to you could make a target-diffuser to make sure you hit the bowl... :D
well i think the reason he used red is cause it helps from hurting your eyes
