For reasons that most rational consumers can’t fathom, a not inconsiderable segment of the population believes the key to their continued survival during a pandemic unprecedented in modern times is to stockpile toilet paper. This leaves those of us not compelled to act based on the whims of our bowels looking at bare racks in the paper product aisle more often than not.
Which makes it the perfect time for [Ariel Yahni] to develop his remote controlled toilet paper roll. With this gadget deployed, you just might have a chance at drawing the Karens away from all the rolled gold long enough to grab yourself a pack. Even if it doesn’t distract the other
competitors shoppers, you can at least enjoy the looks on their faces as it scurries by.
The project starts with, of all things, popsicle sticks. These are used to make a reinforced platform to which the two motors, radio receiver, speed controller, and battery are mounted. With some clever packing, [Ariel] is able to (tightly) fit it inside of a cardboard tube with just the bottoms of the two wheels protruding through cutouts. A careful wrapping with toilet paper is then used to give it the look of a partially used roll, including a trailing “tail” that flutters in its wake.
In the video after the break, you can see [Ariel] take his roll of motorized TP through a local mall for a test drive. We’re sorry to say that nobody appears to make a wild dive for it during the test. But that could be because the video was recorded back in December before people had resorted to fighting over toiletries. It also explains why he was able to get into a mall in the first place.
Just think, if we had embraced the high-tech toilets of the future back when we had a chance, we could have avoided this whole thing. As far as dystopias go, this one is shaping up to be pretty weird.

LEDs and blinky projects are great, and will likely never fade from our favor. But would you look at this sweeping beauty? This mesmerizing display is made from 36 micro servos with partial Popsicle sticks pasted on the arms. After seeing a huge display with 450 servos at an art museum, [Doug Domke] was inspired to make a scaled-down version.
What [Doug] didn’t scale down is the delightful visuals that simple servo motion can produce. The code produces a three-minute looping show that gets progressively more awesome, and you can stare at that after the break. Behind the pegboard, a single, hardworking Arduino Uno controls three 16-channel PWM controllers that sweep the servos. We like to imagine things other than Popsicle sticks swirling around, like little paper pinwheels, or maybe optical illusion wheels for people with strong stomachs.
You won’t see these in the video, but there are five ultrasonic sensors mounted face-up on the back of the pegboard. [Doug] has optional code built in to allow the servo sticks to follow hand movement. We hope he’ll upload a demo of that feature soon.
Servos can be hypnotic as well as helpful, as we saw in this 114-servo word clock.

We feature hacks on this site of all levels of complexity. The simplest ones are usually the most elegant of “Why didn’t I think of that!” builds, but just occasionally we find something that is as much a bodge as a hack, a piece of work the sheer audacity of which elicits a reaction that has more of the “How did they get away with that! ” about it.
Such a moment comes today from [Robinlol], who has made an SD card socket. Why would you make an SD card socket when you could buy one is unclear, beyond that he didn’t want to buy one on an Arduino shield and considered manufacture his only option. Taking some pieces of wood, popsicle sticks, and paperclips, he proceeded to create a working SD card of such bodgeworthy briliance that even though it is frankly awful we still can’t help admiring it. It’s an SD card holder, and despite looking like a bunch of bent paperclips stuck in some wood, it works. What more could you want from an SD card holder?
Paperclips are versatile items. If an SD card holder isn’t good enough, how about using them in a CNC build?
[alvenh] has come a long way since he was a kid, but he kept the bag of popsicle sticks from his childhood. When he set out to build a clock for himself, he remembered his stored treasure and made something unexpectedly good out of the humble material. We’ve seen some neat stuff made with popsicle sticks before, but they usually retain their familiar shape.
[alvenh] began by choosing a style for his clock. We don’t know how he looked at a bag of sticks and thought, “Old English Georgian bracket clock with a bell top,” but if Hackaday teaches anything, it’s that some people just have a wider vision for the world. Next he laminated the sticks together or used them as a veneer for a thinner sheet of plywood to make his base materials.
An incredible amount of work went into the clock as he did things like sanding large contours using a jar for a form, or cutting mortise and tenons into craft sticks. [alvenh] even painted the face of the clock using his German Shepard as a model. Finally he installed an antique movement into the creation. The final result is stunning, and the build log is fun to read through.
