Hyundai Mini 45 EV Is A Small Car With Grand Ambitions

December 23, 2020 by Roger Cheng 20 Comments

One of Hyundai’s recent concept cars was an electric vehicle named “45” in honor of its inspiration, another concept car from 45 years ago. When footage of a child-sized “Mini 45” surfaced, it was easy to conclude the car was a motorized toy for children. But Jalopnik got more information from Hyundai about this project, where we learned that was not nearly the whole picture.

The video (embedded below) explained this little vehicle is a concept car in its own right, and most of the video is a scripted performance illustrating their concept: using technology to help calm young patients in a hospital, reducing their anxiety as they faced treatment procedures. Mini 45 packs a lot more equipment than the toy cars available at our local store. The little driver’s heartbeat and breathing rate are monitored, and a camera analyzes facial expressions to gauge emotional stress. The onboard computer has an animated avatar who will try to connect with the patient, armed with tools like colorful animations, happy music, candy scent dispenser, and a bubble-blowing machine.

Bubbles, The People-Pleasing Pandemic Panda

July 13, 2020 by Kristina Panos 10 Comments

This year, [Thomas]’ neighborhood has gone from a quiet burg to a bustling lane full of families and children who go out walking for exercise and a change of scenery. Early on, a game emerged to distract children from the pandemic by turning these walks into bear hunts — that is, looking for stuffed bears sitting in the windows of houses and keeping count of them.

With no stuffed bears in the house, he decided to join in the fun by pasting up a 2D panda bear in the window that’s cute enough to calm anyone’s nerves. That was fun for a while, but then he turned it up to eleven by making an interactive 3D version named Bubbles the Bear that blows bubbles and speaks in a friendly voice.

Bubbles sits in a second-story window and waits for passers-by to press one of the buttons mounted on the utility pole below. Both buttons are wired to a 433MHz remote that sends a signal to an ESP32 in Bubbles’ habitat that says it’s time to perform.

We particularly like the bubble maker that [Thomas] designed, which aims a blower fan with an air concentrator at a carousel of 3D printed bubble wands. Both the fan and the carousel can be controlled with a custom web app, and he gets an email every time Bubbles has a visitor that tells him how much bubble liquid is left. Check out the fun-size demo after the break.

Bubbles are fun, especially if you can make them in extremely large quantities. Bubbles can also do work — remember this next time you need a random number generator.

Blow 14,000 Bubbles Per Minute With This 3D Printed Contraption

August 12, 2015 by James Hobson 34 Comments

Like bubbles? Then you’ll love this 3D printed bubble blowing machine. It’s capable of blowing approximately 14,000 bubbles… per minute.

Designed and released on Thingiverse, the array of bubble orifices are 3D printed, as well as the gears and chain that rotate the belt of bubbles. The only thing not 3D printed is the 5 gallon bucket, some aluminum extrusion for mounting it rigidly, and the 50RPM motor that spins it around.

Place the bucket in your driveway, hook up a big fan behind it, and Bob’s your uncle — you’ve got 14,000 bubbles a minute to play with. Is it bad we want to see someone set this up inside a house?

Ephemeral Photographs Staged With Artful Inventions

December 8, 2014 by Sarah Petkus 11 Comments

[Gordon Kirkwood’s] focus as a photographer is in capturing ephemeral phenomena, that is, things that are exhilarating to see but also fleeting. In the pursuit of documenting such blips of beauty found in the natural word, he has taken on engineering the circumstance through which they occur by means of technology.

One of the amazing mechanical creations he’s constructed to aid in his photography is a large computer controlled, bubble blower. A few stepper motors work to dilate three segments of soap-soaked rope engaged at 120 degree angles to create a triangular aperture. When the aperture closes, the segments overlap slightly, covering themselves with a consistent coating of suds. When the segments stretch apart, a fan blows a current of air towards the center, pushing the sheath of fluid into ginormous glimmering orbs which he uses as the focal point in some of his photographs.

More currently, [Gordon] has been developing a body of work that involves zapping botanical subject matter with a quarter-million volts from a portable arc producing device he’s created and capturing the reaction with an ultra low-tech camera (the kind with the bellow and sheet you hide under while exposing the film). Using a method all his own, the shots recorded on large format film are claimed to turn out with even more clarity than any current digital camera in use today. [Gordon] has launched a crowd funding campaign to support a pilgrimage to the majestic island of Hawaii, where he’ll use his lightning producing apparatus on ten different specimens of tropical plant life so that he can record the outcome with his tried and proven technique. (see below an artsy shot of his lightning summoner)

Sometimes Kickstarter isn’t so much about commercialism as it is starting a dialogue with the world and beginning a personal adventure. May the journey lead to new inventions and larger, more ambitious projects! Oh yeah- the bubble blowing machine is a must-see in action. Wicked cool:
