Some aspects of humanity affect all of us at some point in our lives. Whether it’s getting caught in the rain without an umbrella, getting a flat tire on the way to work, or upgrading a Linux package which somehow breaks the entire installation, some experiences are truly universal. Among these is pulling a few squares of toilet paper off the roll, only to have the entire roll unravel with an overly aggressive pull. It’s possible to employ a little technology so that none of us have to go through this hassle again, though.
[William Holden] and [Eric Strebel] have decided to tackle this problem with an innovative bearing of sorts that replaces a typical toilet paper holder. Embedded in the mechanism is a set of magnetic discs which provide a higher resistance than a normal roll holder would. Slowly pulling out squares of paper is possible, but like a non-Newtonian fluid becomes solid when a higher force is applied, the magnets will provide enough resistance when a higher speed tug is performed on the toilet paper. This causes the paper to tear rather than unspool the whole roll, and also allows the user to operate the toilet paper one-handed.
This is a great solution to a problem we’ve all faced but probably forgot about a minute after we experienced it. And, it also holds your cell phone to keep it from falling in the toilet! If you’d like to check out their Kickstarter, they are trying to raise money to bring the product to market. And, if you want to upgrade your toilet paper dispenser even further, there’s also an IoT device for it as well, of course.

Our first impression of this IoT toilet paper roll was that somebody was pulling our leg. Watching the infomercial-esque video below is alternately hilarious and horrifying, but it leaves you with the unmistakable feeling that this is all a joke, and a pretty good one at that. Right up until you get to the big Kimberly-Clark logo at the end, that is, and you realize that the international paper concern must be looking at this seriously.
When you read [zvizvi]’s Instructables post, you find out that this project is indeed a legitimate attempt to meld an Amazon Dash button with your toilet paper dispenser. For his proof-of-concept build, [zvizvi] started with a gag “talking TP” roll off eBay, designed to play back a voice clip when the paper is used. It had all the right guts, and being just the size for a Wemos Mini and an accelerometer for motion detection was a bonus. The smart spindle can tally the amount of paper used, so you’ll never be caught without a square to spare. And of course, critical TP usage parameters are uploaded to a cloud server, so that more toilet paper can be rushed to your door when you’re getting low.
The whole idea, including justification based on monitoring TP use as a proxy for bowel health, seems ridiculous, but we suspect there may be some brilliance here. Joke if you will, but in the end it’s probably better than an Internet of Farts.

Over or under? Standing or sitting? Truly, toilet paper has been the focus of the most irreconcilable arguments ever. The folks on the Arduino Stack Exchange have a far more important question: how do you trigger an alarm when your TP supply is low?
[user706837] asked the Internet this question in response to his kids never replacing an empty roll. This eliminates the most obvious means of notifying someone of an empty roll – looking at it before you sit down – and brings up a few interesting engineering challenges.
Most of the initial ideas deal with weight or some sort of light sensor that can differentiate between the white TP and the brown roll. A much, much more interesting solution puts a radioactive source in the TP holder’s spring-loaded rod and uses a sensor to detect how much TP is left. A quick back-of-the-wolfram calculation suggests this might be possible, and amazingly, not too dangerous.
We’re turning this one over to you, Hackaday readers. How would you design an empty toilet paper alarm? Bonus points awarded for ingenuity and cat resistance.

Sunlit LCD screen
[A.J.] did some experiments and managed to replace his LCD backlight using fiber optics and the sun.
Game Boy LCD Repair
[Alan] found that he could fix dead columns on his Game Boy LCD screen with a little reflow work on the connector.
3DS Design Flaw?
Anyone having problems with the way their Nintendo 3DS closes? [Jeroen] noticed that his screen touches the other half of the device when closed. He added rubber feet to protect it, but we wonder if anyone else has noticed this issue?
Mac TP dispenser
This one takes iLife to a new level. Never poop without Apple’s consent again thanks to this Macintosh toilet paper dispenser. [Thanks Rob]
Children are the future
Here’s a heart warming way to end; [Bret] is teaching his 5-year-old son to solder. There’s a video that is sure to put a smile on your face. You’ll remember [Bret] (aka [FightCube]) from the adjustable prank box, a few 555 timer contest submissions, and several other hacks. We expect big things from your progeny!
Solving the age old problem of… wait, what problem are they solving? These students at UC Berkeley have built a toilet paper dispenser prototype. Not only does it meter out an exact amount for you, it will fold it and cut it as well. They mention this being the perfect accessory for a high tech bathroom, and we can agree. To be serious though, in public places, metering out limited amounts of toilet paper at a time could possibly result in major cost savings. We think the next prototype should have different preference settings such as; wadded, folded, or wrapped around your hand. Anyone else’s mind suddenly filled with unpleasant imagery?
