AI-Controlled Twitch V-Tuber Has More Followers Than You

Surely we have all at least heard of Twitch by now. For the as-yet uninitiated: imagine you had your own TV channel. What would you do on it? Although Twitch really got going as a place for gamers to stream the action, there are almost as many people jamming out on their guitars, or building guitars, or just talking about guitars. And that’s just the example that uses guitars — if you can think of it, someone is probably doing it live on Twitch, within the Terms of Service, of course.

Along with the legions of people showing their faces and singing their hearts out, you have people in partial disguise, and then you have v-tubers. That stands for virtual tubers, and it just means that the person is using an anime avatar to convey themselves.

Now that you’re all caught up, let’s digest the following item together: there’s a v-tuber on Twitch that’s controlled entirely by AI. Let me run that by you again: there’s a person called [Vedal] who operates a Twitch channel. Rather than stream themselves building Mad Max-style vehicles and fighting them in a post-apocalyptic wasteland, or singing Joni Mitchell tunes, [Vedal] pulls the strings of an AI they created, which is represented by an animated character cleverly named Neuro-sama. Not only does Neuro-sama know how to play Minecraft and osu!, she speaks gamer and interacts regularly with chat in snarky, 21st century fashion. And that really is the key behind Twitch success — interacting with chat in a meaningful way.

3D Printer Filament From Reel-to-Reel Audio Tapes

At heart, 3D printers are just machines that can melt plastic “wire” into interesting shapes. It’s well-known and oft-lamented that plastic of various sorts has been used to make all manner of household objects that might eventually end up in landfill or otherwise littering the environment. With these facts in mind and a surplus of tape, [brtv-z] decided to see if he could recycle some old reel-to-reel audio tapes into working filament for a 3D printer.

The homebrew rig to convert old audio tape into the unconventional filament

This isn’t the first time he has tried to print with unusual second-hand polymers, back in 2020 he pulled of a similar trick using VHS tape. Through experimentation, it was soon determined that seven strands of quarter-inch tape could be twisted together and fused to form a very tough-looking filament approximately 1.7 mm in diameter, which could then be fed into the unsuspecting printer.

The resulting prints are certainly different in a number of respects from using virgin filament. The material is porous, brittle and (unsurprisingly) rather rusty-looking, but it does have some interesting properties.  It retains its magnetism and it catches the light in an unusual way. The video is after the break (in Russian, but YouTube does a reasonable job of generating English captions).

Don’t have any tape handy? No worries, we’ve also covered machines that can recycle plastic waste into filament before. In fact, two of them even won the 2022 Hackaday Prize. What else could you melt down that might otherwise be thrown away?

Organic Fibonacci Clock Is All About The Spiral

Whether you’re a fan of compelling Tool songs, or merely appreciate mathematical beauty, you might be into the spirals defined by the Fibonacci sequence. [RuddK5] used the Fibonacci curve as the inspiration for this fun clock build.

The intention of the clock is not to display the exact time, but to give a more organic feel of time, via a rough representation of minutes and hours. A strip of addressable LEDs is charged with display duty. The description is vague, but it appears that the 24 LEDs light up over time to show the amount of the day that has already passed by. The LEDs are wound up in the shape of a Fibonacci spiral with the help of a 3D printed case, and is run via a Wemos D1 microcontroller board.

It’s a fun build, and one that we can imagine would scale beautifully into a larger wall-hanging clock design if so desired. It at once could display the time, without making it immediately obvious, gradually shifting the lighting display as the day goes on.

We’ve seen other clocks rely on the mathematics of Fibonacci before, too. If you’ve cooked up your own fun clock build, don’t hesitate to let us know!
