Most infinity mirrors are just minor variations on the same old recipe. Take a frame, add a normal mirror in the back, a one-way mirror on the front, and put some LEDs between them. [Stevens Workshop] took a slightly different approach and built an escape tunnel coffee table that really caught our attention.
To create the tunnel and ladder illusion, [Steven] kept the mirrors, but made a deeper wood frame, installed a light bulb in an industrial-looking socket instead of the usual LEDs, and added a single ladder rung. The end result makes for a very interesting conversation piece, and some of us prefer it to the multicolored LED look. Though he added his own touches, the idea was actually borrowed from from [asthhvdrt36] and [BreezleSprouts] on Reddit who used slightly different light and ladder designs.
While there’s nothing groundbreaking here, it’s certainly a case of “why didn’t I think of that”. Sometimes the old and familiar just needs a different perspective to create something fascinating. One of the advantages of the classic infinity mirror is the thin profile, which we’ve seen integrated into everything from guitars to coasters.
Some hackers make functional things that you can’t allow to be seen in polite company. Others make beautiful things that could come from a high-end store. [Marija] falls into the second category and her interactive LED coffee table would probably fetch quite a bit on the retail market. You can see a video of the awesome-looking table, below.
It isn’t just the glass, MDF, and pine construction. There’s also a Bluetooth interface to a custom Android application from [Dejan], who collaborated on the project. However, if you aren’t comfortable with the woodworking, [Marija’s] instructions are very detailed with great pictures so this might be a good starter project.

[Robby Cuthbert,] an artist and designer based out of Fort Collins, Colorado is creating stable cable tables that are simultaneously a feat of engineering and a work of art.
[Cuthbert’s] tables are held together by 1/16″ stainless steel cables that exert oppositional tensions that result in a structurally stable and visually appealing coffee table. In his video, [Cuthbert] leads us through his process for creating his tables, step by step. [Cuthbert] starts by cutting out bamboo legs on his CNC mill. He then drills holes in each leg for cables and mounts each leg on his custom table jig. Then, he attaches the stainless steel cabling taking care to alternate tension direction. The cables are threaded through holes in the legs and affixed with copper crimps. After many cables, he has a mechanical structure that can support his weight that also looks fantastic. All in all, [Cuthbert’s] art is a wonderful example of the intersection of art and engineering.
If we’ve whet your appetite, fear not, we have featured many tension based art/engineering hacks before. You might be interested in these computer-designed portraits or, if the thought of knitting by hand gives you the heebie-jeebies, the Autograph, a string art printer might be more your style.

Redditor [ squishy0eye] lacked a coffee table and wanted an infinity mirror. So, in a keen combination of the two, she built an infinity mirror table the resembles a nighttime cityscape.
Skimming over many of table’s build details, [squishy0eye] paused to inform the reader that an MDF base was used underneath the mirrors, with a hole drilled for the future power cable. For the top pane, she overlaid privacy screen mirror film onto tempered glass, turning it into a one-way mirror. The bottom pane is acrylic plastic due to the need to drill holes to hide the cables for each ‘building’ — the same mirror film was applied here as well. Wood was cut into rectangles for the building shapes and super glued around the holes and in the corresponding spots underneath to prevent any bowing in the acrylic. A small gap was left in each ‘building’ to run the 5050 non-waterproof LED strips around and back into the hole for power.

[Daniel Perdomo] and two of his friends have been working on a mechanical version of Pong for the past two years. We can safely say that the final result is beautiful. It’s quite ethereal to watch the pixe–cube move back and forth on the surface.
[Daniel] has worked in computer graphics for advertising for more than 20 years. However, he notes that neither he nor his friends had any experience in mechanics or electronics when they began. Thankfully, the internet (and, presumably, sites like Hackaday) provided them with the information needed.
The pong paddles and and pixel (ball?) sit onto of a glass surface. The moving parts are constrained to the mechanics with magnets. Underneath is a construction not unlike an Etch A Sketch for moving the ball while the paddles are just on a rail with a belt. The whole assembly is made from V-groove extrusion.
Our favorite part of the build is the scroll wheel for moving the paddle back and forth. For a nice smooth movement with some mass behind it, what’s better than a hard-drive platter? They printed out an encoder wheel pattern and glued it to the surface. The electronics are all hand-made. The brains appear to be some of the larger Arduinos. The 8-bit segments, rainbow LEDs, etc were build using strips glued in place with what looks like copper foil tape connecting buses. This is definitely a labor of love.
It really must be seen to be understood. The movement is smooth, and our brains almost want to remove a dimension when watching it. As for the next steps? They are hoping to spin it up into an arcade machine business, and are looking for people with money and experience to help them take it from a one-off prototype to a product. Video after the break.

[Nick Offerman] is a pretty serious wood worker. He likes to make crazy stuff including organic looking tables out of huge chunks of wood. Clearly, the wood doesn’t come out of the ground shaped like the above photo, it has to be intensely worked. [Nick] doesn’t have a huge saw or belt sander that can handle these massive blocks of wood so he built something that could. It’s a jig that allows him to use a standard wood router to shave each side down flat.
The process starts by taking a piece of tree trunk and roughing it into shape with a chainsaw. Once it is flat enough to not roll around, it’s put into a large jig with 4 posts. Horizontal beams are clamped to the posts and support a wooden tray which a wood router can slide back and forth in. The router’s cutting bit sticks out the bottom of the tray and slowly nibbles the surface flat. Once one side is flat, the block is rotated and the flat side is used as a reference to make all the other sides square to the first. After flattening, sanding and finishing the block results in a pretty sweet piece of functional artwork.
After [Travis]’s media server died a couple months ago, his brother [Nick] secretly plotted to replace it for Christmas. Admitting it to be an “asinine Rube Goldberg” arrangement, [Nick] wanted something custom and remarkable for his sibling. Rather than go the normal SATA route, 38 USB hot-swap laptop drives were clustered together inside a custom leather enclosure with a bronzed glass top.
[Nick] picked up 45 of the 500GB drives for only $350 and designed the project around those. He spent $1000 on matching metal docks for each of them, powered by $800 worth of PCIe quad independent USB controllers – no hubs. A $550 Xeon motherboard with 14 USB ports, 16GB of RAM, a basic video card and a 1000W power supply rounded out the electronics.
Under Windows 8.1 all drives are arranged in a single giant array under Storage Spaces, no raid.
Everything was built into a wood-framed coffee table wrapped in high-end leather that [Nick] spent 65 hours hand stitching himself. Fancy brass corner braces hold the frame square. All the wires were run underneath the table so the visible surfaces are clean and clear. The table structure is lifted up on legs made from half-inch square barstock bent into a hairpin and bolted to the underside.
All together [Travis]’s Zerg-Berg media server cost in the range of $4500. [Nick] intends it to be something that lasts him a very long time.
See the video below for [Nick]’s
rationalization explanation of the hardware and methods chosen.
