Miniature golf is one of those pastimes that can be molded and redefined pretty much indefinitely. Like pinball machines which also come in an endless variety of flavors, each hole of a miniature golf course is a vignette with a theme designed to tie cleverly into its objective. Mini golf has come a long way from windmills and draw-bridges, and with technology thrown in the mix you end up with works of art like [Dan Rosenfeld’s] project, “Sleepwalkers” which go so far as to paint a holographic world for the player to interact with.
“Sleepwalkers” was commissioned by Urban Putt, a chain that accommodates for dense city spaces by building their courses indoors. Designed specially for its location, the hologram acts as a narrative told by tiny characters living within the walls of the historic building the golf course occupies. At a certain point during the game, a player is prompted to purposely place their ball into an opening in one of the old walls where it quickly rolls somewhere out of sight. When the player peeks through a series of holes dotted throughout the surface in order to find where it went, they discover another world sandwiched between wood beams and insulation. This becomes the setting of a short exchange with a character who the player must interact with in order to get their ball out of hock. The spectral glow and dimensionality of the wall’s inhabitants is created using a projection along with the Pepper’s Ghost illusion, a classic trick with angles and mirrors. Once the player’s hand enters into the Sleepwalker’s world through larger holes in the wall, a camera used for depth cues maps the projection to its presence. The tiny figure then uses the hand in a series of dioramas as a tool to climb on in order to reach the area where the player’s ball is trapped. After a joint effort, a linear actuator and sensor help to complete the illusion that the projected character is pushing the golf ball free into the real world where the player can then retrieve it and continue on to the next hole.
The traditional antics created by swinging pendulums and spinning windmills will always charm us, but the use of technology to take us into a new world will leave us with something more. You can see it on the faces of those interacting with [Rosenfeld’s] installation for the first time:

Listening tests reveal significant sound quality differences between various digital music storage technologies. Finally the audiophile press is tackling the important questions. This listening test looks at the difference between two four-bay NAS boxes, with one making the piano on Scherzo and Trio from Penguin Café Orchestra’s Union Cafe sound more Steinway-like, while another NAS makes it sound more like a Bosendörfer. Yes, your choice of digital storage medium can change the timbre of a piano. Another gem: “Additionally, the two units also had different processor architectures, which might also affect perceived audible differences.” There must be a corollary to Poe’s Law when it comes to audiophiles…
[10p6] has begun a project that can play every old Atari cartridge. Right now it’s just a few bits of plastic that fits every non-Jaguar Atari cartridge, but it’s a start.
The Android IMSI-Catcher Detector. You’ve heard about Stingrays, devices used by law enforcement that are basically fake cell towers. These Stingrays downgrade or disable the encryption present in all cellphones, allowing anyone, with or without a warrant, to listen in on any cell phone conversation. Now there’s an effort to detect these Stingrays. It’s open source, and they’re looking for volunteers.
[Rob] sent in something that’s the perfect application of projection mapping. It’s called Face Hacking, and it’s pretty much just a motion capture systems, a few projectors, a whole lot of CG work, and just a tiny bit of dubstep. It look cool, but we’re wondering what the applications would be. Theatre or some sort of performance art is the best I can come up with.
A while ago, [4ndreas] saw a 3D printed industrial robot arm. He contacted the guy for the files, but nothing came of that. [4ndreas] did what anyone should do – made his own 3D printable industrial robot arm. The main motors are NEMA 17, and printing this will take a long time. Still, it looks really, really cool.
Giant fresnel lens is dangerous fun
Here’s an interesting, and rather dangerous, use for those old big screen TVs that are frequently listed for FREE on Craigslist. With the lens from the old TV built into an adjustable wooden frame, [Grant] was able to melt a stack of pennies, instantly burn wood, melt spots in concrete, and serve his family a cooked egg… Cool.
Projection mapping app helps create hologram like performance stage
[Aimino] used an iPad, a mobile projector, and a mosquito screen to create a trippy hologram like stage. It might not seem like much at first, but it’s actually a pretty interesting effect. Watching the video makes me wonder what other applications this could have in the near future.
The world’s strongest magnet
At a cost of over $14 million dollars and weighing in at 35 tons, the 45 Tesla Hybrid is the strongest DC magnet on Earth. It’s powerful enough that the film crew couldn’t even safely get in to take footage of it. Over half of their camera tapes were wiped clean just while being in the same facility that houses it!
Virtual Body chair uses 4 of our 5 senses
Created in the hopes of providing a VR experience for seniors with mobility problems who can no longer travel the world, Tokyo Metropolitan University’s Ikei Laboratory presents the ‘Virtual Body’ exhibition. Included are a 3D monitor, a pair of headphones, a fan to create breezes and spread scents, a chair that moves and vibrates, and moving foot pedals.
Iron Man laser gauntlet pops balloons with ease
If you’re an Iron Man fan with disposable income, you might want to check out this functional full metal laser gauntlet. Built from scratch using no blueprints or guides, [AnselmoFanZero] sells them for around $3K USD.
