Most Hackaday readers are likely to be familiar with the infinity mirror, a piece of home decor so awesome that Spock still has one up on the wall in 2285. The idea is simple: two parallel mirrors bounce and image back and forth, which creates a duplicate reflection that seems to recede away into infinity. A digital version of this effect can be observed if you point a webcam at the screen that’s displaying the camera’s output. The image will appear to go on forever, and the trick provided untold minutes of fun during that period in the late 1990’s where it seemed everyone had a softball-shaped camera perched on their CRT monitors.
It works about how you’d expect: the stream is captured, manipulated through various filters, and then rebroadcast through Twitch. This leads to all sorts of weird visual effects, but in general gives the impression that everything is radiating from a central point in the distance.
While [Matt] acknowledges that there are probably not a lot of other people looking to setup their own Twitch feedback loops, he’s still made his Python code available for anyone who might be interested. There’s a special place in Hacker Valhalla for those who release niche software like this as open source. They’re the real MVPs.
Infinity mirrors are awesome. They’re great conversation pieces, and even more fun to stare into forever and ever and ever and ever… They can be tricky to build, but there’s actually a really easy way to do it, and [William] shows us how.
The way a infinity mirror works is it uses a one-way mirror with lights around the perimeter in front of a regular mirror. The majority of the light gets bounced back and forth between the two mirrored surfaces, and because you can see into the one-way mirror, you get that really cool infinity effect.
Now if you went out and bought a one way mirror, built the frame, and put it all together — it’d be a lot of work. But there’s an easier way to do it on the cheap. Mirrored car tint foil. Although it’s illegal on your car in most states, it’s still pretty easy to find. Continue reading “The Easiest Infinity Mirror Build”→
Here’s a cool crowdfunding campaign that somehow escaped the Hackaday Tip Line. It’s a remote control SpaceShipOne and White Knight. SpaceShipOne is a ducted fan that has the high-drag feathering mechanism, while White Knight is a glider. Very cool, and something we haven’t really seen in the scratchbuilding world.
[Sink] has a Makerbot Digitizer – the Makerbot 3D scanner – and a lot of time on his hands. He printed something, scanned it, printed that scan… you get the picture. It’s a project called Transcription Error.
The Apple ][, The Commodore 64, and the Spectrum. The three kings. Apple will never license their name for retro computer hardware, and there will never be another computer sold under the Commodore label. The Spectrum, though… The Sinclair ZX Spectrum Vega is a direct-to-TV console in the vein of [Jeri Ellisworth]’s C64 joystick doohickey.
Infinity mirrors are simple enough to make; they’re just one mirror, some LEDs, and another piece of glass. How about a 3D infinity mirror? They look really, really cool.
There’s a lot going on here, starting with the cabinet which is 30″x30″ and has some custom mirrored glass necessary because of a square cut-out in the middle of the front pane. The two mirrors face each other, with a strip of LEDs in between which accounts for the “infinity” part of the build. This is popular but usually it’s usually just the mirror and lights. In this case that special cut-out is a cubby for a glass. Place it in there and the rest of the build will mix you up a tasty beverage.
There is a second chamber in the enclosure behind the rear mirror. This houses the components that mix up the drinks. Raw materials are dispensed from 1.25L plastic bottles. The extra special part of the build is that since it is a senior project, all the driving circuitry uses roll-your-own boards.
[Evan] wrote in to let us know about the LED matrix infinity mirror he’s been working on. [Evan] built a sizable LED matrix out of WS2812B LEDs and mounted them to a semi-reflective acrylic sheet, which makes a pretty awesome infinity mirror effect.
Instead of buying pre-wired strands of serial LEDs like we’ve seen in some other projects, [Evan] purchased individual WS2812 LEDs in bulk. Since the LEDs just had bare leads, [Evan] had to solder wires between each of his 169 LEDs (with some help from a few friends). After soldering up hundreds of wires, [Evan] drilled out holes for each LED in a piece of semi-reflective acrylic and inserted an LED into each hole.
To create the infinity mirror effect, [Evan] mounted the LED matrix behind a window. [Evan] put some one-way mirror film on the outside of the window, which works with the semi-reflective acrylic to create the infinity mirror effect. The LEDs are driven by an Arduino, which is controlled by a couple of free programs to show a live EQ of [Evan]’s music along with patterns and other effects.
We don’t think we’ve seen an Infinity Mirror Clock before, but we love this new twist on an old favorite. Different colors distinguish between seconds, minutes and hours, and an additional IR sensor detects when someone is directly in front of the clock and switches the LEDs off, allowing it to be used as a normal mirror. This build is the work of [Dushyant Ahuja], who is no stranger to hacking together clocks out of LEDs. You can tell how much progress he’s made with the mirror clock by taking a glance at his first project, which is an impressive creation held together by jumbles of wire and some glue.
[Dushyant] has stepped up his game for his new clock, attaching an LED strip along the inside of a circular frame to fashion the infinity mirror effect. The lights receive a signal from an attached homemade Arduino board, which is also connected to a real-time clock (RTC) module to keep time and to a Bluetooth module, which allows [Dushyant] to program the clock wirelessly rather than having to drag out some cords if the clock ever needs an adjustment.
Stick around after the jump for a quick demonstration video. The lights are dazzling to watch; [Dushyant] inserted a stainless steel plate at the center of the circle to reflect the outer rim of LEDs. After a quick rainbow effect, it looks like the mirror enters clock mode. See if you can figure out what time it is. For a more step-by-step overview of this project, swing by his Instructables page.
If infinity mirrors aren’t cool enough, the 10-foot-tall infinity portalshould blow you away. Strictly speaking, the mirror itself is only 7’x4′, but you’ll still find yourself engulfed in the archway. The portal began as a simple prototype that we covered earlier this summer, which was just a frame of 2×4’s, some acrylic and LED strips. It works by putting lights between a two-way mirror and another mirror, reflecting most light internally and creating the illusion of depth.
The giant archway also began as a small-scale prototype, its shape and engravings carved out by a laser cutter. Once they were satisfied with its design, it was time to scale things up. The full-sized portal needed a a tremendous amount of stability, so the guys at Freeside built the base from wooden palettes. They needed the portal to travel to a few different venues, so the rest of the frame breaks down into components, including a removable wooden frame from which the acrylic hangs. A Teensy 3.0 runs all the WS2812 LED strips, which were chosen because each of their LEDs is individually addressable.
Check out the video below for an extremely detailed build log, which should give you a better idea of how massive and impressive this portal really is!
