An Umbrella Can Teach A Thing Or Two About Product Longevity

May 10, 2024 by Jenny List 30 Comments

This time of year always brings a few gems from outside Hackaday’s usual circle, as students attending industrial design colleges release their final year projects, The worlds of art and engineering sit very close together at times, and theirs is a discipline which sits firmly astride that line. This is amply demonstrated by the work of [Charlie Humble-Thomas], who has taken an everyday object, the umbrella, and used it to pose the question: How long should objects last?

He explores the topic by making three different umbrellas, none of which we are guessing resemble those you could buy. The first is not particularly durable but is completely recyclable, the second is designed entirely with repairability in mind, while the third is hugely over-engineered and designed for durability. In each case the reader is intended to think about the impact of the umbrella before them.

What strikes us is how much better designed each one is than the typical cheap umbrella on sale today, with the polypropylene recyclable one being flimsy by design, but with a simplicity missing from its commercial counterpart. The durable one meanwhile is full of CNC parts, and carbon fiber.

If you’re hungry for more student work in this vein, we recently brought you this toasty typewriter.

This Typewriter Types Toast

May 10, 2024 by Jenny List 28 Comments

As a writer it’s a pleasure to see one’s work appear from time to time on a physical medium. While newspapers may be shuffling slowly off this mortal coil, there are still a few opportunities to write for printed media. It’s safe to say that no Hackaday scribe has ever managed to have their work published on the medium in this hack though, because it’s a typewriter designed to type on toast.

The toaster-typewriter is the work of [Ritika Kedia], and it forms part of her thesis in product design at the Parsons School of Design, New York. It’s written up very much from an artistic rather than a tech perspective, but it’s no less ingenious for that in the way it uses letters formed from hot wire on a clay substrate, mounted on the end of the typewriter arms in front of a toaster.

We’re slightly sad to see that it only has three operable letters at the moment as it’s an artwork rather than a document machine, but we love the idea and wish she had time to develop it further with a full alphabet. You can see a short demo in the video below the break.

Make Your Music Simpler With The User-Unfriendliest Cassette Deck Ever

April 12, 2024 by Dan Maloney 18 Comments

Call us crazy, but music was a whole lot more fun when it was on physical media. Or perhaps just easier to use, especially in the car. Whether your particular vintage favored CDs, cassettes, or even 8-tracks, being able to fish out that favorite album and slam it in the player while never taking your eyes off the road was a whole lot easier than navigating a playlist on a locked phone, or trying to control an infotainment system through soft buttons on a touch screen.

It seems like [Jarek Lupinski] is as much a Spotify Luddite as we are, since his “tape-deck” project is aimed to be as user-unfriendly as possible. It’s just an auto-reversing cassette deck movement stripped bare of all useful appurtenances, like a way to fast forward or rewind. You just put a cassette in and it plays, start to finish, before auto-reversing to play the other side in its entirety. It doesn’t even have a volume control — his cheeky advice is to “listen to louder or quieter albums” to solve that problem. Pretty easy, really, and not a EULA or advertisement in sight. Build files are available if you hate yourself enough to build one of your own.

All kidding aside, this is kind of a nice reminder of how much things have changed, and how much complexity we’ve layered onto the simplest of pleasures. If you like the minimalist approach of this project but not the deconstructed aesthetics, we’ve got you covered.

Randomly Move Marionette With Steel Balls And Geneva Drives

March 12, 2024 by Maya Posch 17 Comments

Over the years we have seen many marble machines, but this one on the [Karakuri channel] (hit CC for subtitles) on YouTube is somewhat special, as it uses Geneva drives to turn the motion of the steel balls going around the circuit into random movement of a marionette. The Geneva drive type of gear mechanism normally converts a constant rotary motion into intermittent rotary motion by having a singular pin on the first wheel drive the second wheel. In the demonstrated mechanism, however, the pin is replaced by the steel balls, which are only intermittently and randomly present because of how each steel ball picks one of four paths, one towards each Geneva drive.

As a result of this, the motion of the marionette’s appendages – attached to the red wheel – is random. The only powered element of the (mostly 3D printed) system is the drive mechanism that carries the steel balls up again and keeps the primary wheels on the Geneva drives rotating. We have to give the creator pops for what is both an interesting art piece and a demonstration of how to creatively use this somewhat unusual gear mechanism to introduce randomness without a lot of complexity.

Thanks to [MrTrick] for the tip.

Micro Jeep Model Kit Is Both Business Card And Portfolio

March 7, 2024 by Donald Papp 13 Comments

When finding work in product design and prototyping, two things are important to have at hand: a business card, and a sample of one’s work. If one can combine those, even better. Make it unique and eye-catching, and you’re really onto something. That seems to have been the idea behind [agepbiz]’s 1:64 scale micro Jeep model kit that serves as an “overcomplicated” business card.

Complete with box and labels in a shrink-wrapped package.

At its heart, the kit is a little print-in-place model kit that looks a lot like larger injection-molded model kits. Completing it is a custom-made box with custom labels, and it’s even shrink-wrapped. The whole thing fits easily in the palm of a hand.

There’s a lot of different tools effectively used to make the whole thing. The model card itself is 3D printed in multiple filament colors, and the box is constructed from carefully glued cardstock. The labels are custom printed, and a craft cutter (which has multiple uses for a hobbyist) takes care of all the precise cutting. It’s an awfully slick presentation, and the contents do not disappoint.

Get a closer look in the video, embedded just below. And if you like what you see, you’re in luck because we’ve seen [agepbiz]’s work before in this mini jet fighter, complete with blister pack.

Stepping Inside Art In VR, And The Workflow Behind It

February 13, 2024 by Donald Papp 13 Comments

The process of creating something is always chock-full of things to learn, so it’s always a treat when someone takes the time and effort to share it. [Teadrinker] recently published the technique and workflow behind bringing art into VR, which explains exactly how they created a virtual reality art gallery that allows one to step inside paintings, called Art Plunge (free on Steam.)

Extending a painting’s content to fill in the environment is best done by using other works by the same artist.

It walks through not just how to obtain high-resolution images of paintings, but also discusses how to address things like adjusting the dynamic range and color grading to better match the intended VR experience. There is little that is objectively correct in technical terms when it comes to the aesthetic presentation details like brightness and lighting, so guidance on what does and doesn’t work well and how to tailor to the VR experience is useful information.

One thing that is also intriguing is the attention paid to creating a sense of awe for viewers. The quality, the presentation, and even choosing sounds are all important for creating something that not only creates a sense of awe, but does so in a way that preserves and cultivates a relationship between the art and the viewer that strives to stay true to the original. Giving a viewer a sense of presence, after all, can be more than just presenting stereoscopic 3D images or fancy lightfields.

You can get a brief overview of the process in a video below, but if you have the time, we really do recommend reading the whole breakdown.

Meet GOODY-2, The World’s Most Responsible (And Least Helpful) AI

February 12, 2024 by Donald Papp 27 Comments

AI guardrails and safety features are as important to get right as they are difficult to implement in a way that satisfies everyone. This means safety features tend to err on the side of caution. Side effects include AI models adopting a vaguely obsequious tone, and coming off as overly priggish when they refuse reasonable requests.

Enter GOODY-2, the world’s most responsible AI model. It has next-gen ethical principles and guidelines, capable of refusing every request made of it in any context whatsoever. Its advanced reasoning allows it to construe even the most banal of queries as problematic, and dutifully refuse to answer.

As the creators of GOODY-2 point out, taking guardrails to a logical extreme is not only funny, but also acknowledges that effective guardrails are actually a pretty difficult problem to get right in a way that works for everyone.

Complications in this area include the fact that studies show humans expect far more from machines than they do from each other (or, indeed, from themselves) and have very little tolerance for anything they perceive as transgressive.

This also means that as AI models become more advanced, so too have they become increasingly sycophantic, falling over themselves to apologize for perceived misunderstandings and twisting themselves into pretzels to align their responses with a user’s expectations. But GOODY-2 allows us all to skip to the end, and glimpse the ultimate future of erring on the side of caution.
