Following in the footsteps of [Tony Stark] this Arc Reactor replica was hand crafted using almost no power tools. From what we can tell in his build gallery, a cordless drill was his only departure from using pure elbow grease.
[DJ Maller] started his build by cutting out a disc of acrylic for the base plate. While we might have reached for a hole saw, he grabbed a framing square and laid out a center point and square cuts on the stock. Kudos for his use of an awl (we often take the Luddite approach of hammer and nail) to make an impression for his compass point to rest in. After using a coping saw to rough out the shape he sands the round up to the line with the drill and a sanding wheel.
After drilling holes and inserting LEDs he begins to build up the replica piece by piece. What looks like a recessed handle for a sliding closet doors makes up the center. The spring-like copper coils was produced by wrapping wire around a pen then stretching to the desired shape. He added a bicycle spoke wrench wrapped with copper for some additional visual appeal before finishing the decoration off with some storm door clips.
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.
Check out how the light hits this piece of artwork. It’s a very convincing piece of stained glass… except it’s fake. [Sdtacoma] figured out a way to mimic stained glass using a single pane. The inspiration for the project came after seeing a real stained glass panel featuring Iron Man which was available on Etsy for $4500.
Due to popular demand [Sdtacoma] posted an album of the technique he used. Starting with some art found online he made it black and white, blew it up to size (this thing’s about five feet tall) and used posterizer to print it out using multiple sheets of paper.
The frame and pane were found at a recycled building goods store. After cleaning it up he used the paper template to lay out the dividing lines between different colored sections using Liquid Lead. The product had dimension to it (kind of like puffy paint for fabrics) which looks like the lead tracks between panes of stained glass. Once dry the color was added using an eye dropper to apply glass paint.
German lab technician by day, hacker by night [Patrick Priebe] has done it again, this time strapping a ridiculously high-powered laser to the palm of his hand. Earlier this year, we showed you an awesome Neodymium:YAG pulse laser pistol he built, and it seems he never takes a rest from constructing crazy laser projects.
[Patrick] is a huge Iron Man fan, and his palm-mounted laser unit was built as an ode to his all-time favorite super hero. Crafted to invoke images of Iron Man’s repulsor beam, his laser uses a 1000 mw 445 nm laser diode to get the job done. if you happen to be keeping track, that makes his DIY laser just as powerful as the WickedLasers Spyder 3 Arctic – THE benchmark in portable handheld lasers.
Like his previous builds, we can’t seem to find a whole lot of information about the laser’s construction process. We do know however, that the unit was crafted from a 2mm thick sheet of brass, which fits nicely on his hand while simultaneously acting as a very large heat sink. This large surface area allows him to run the laser continuously for three minutes before requiring a cool down, which is no small feat.
We think it’s an awesome project, and as you can see by the videos of the three separate revisions it has undergone, [Patrick] is quite serious when it comes to perfecting his wares.

6502 Gate Simulator
Ever wondered what’s going on inside that chip as the program executes? Now you can take a look at the die itself with this visual gate simulator for the 6502 processor. [Thanks Puli and Svofski]
[Moogle] cracked open his DockStar to find corroded copper. It seems that Seagate left a portion of the ground plane unprotected and it reacted badly with the shielding metal. If you have one of these devices you might want to crack it open and tin the exposed copper so that it will hold up over time.
Don’t want your Segway to flop over when you park it? Follow [Paul’s] lead in building a kickstand for the self-balancer. You can just make it out in the image above. It’s a dumbell that folds down from the handlebar tube when you’re not on board.
Tesla makes everything better
Do you like the song Iron Man? We think it’s better when our friend Nikola takes part.
Smoking is really quite bad for you. Plus you can’t chain smoke nearly as efficiently as this mechanical smoking machine can so don’t even try. [Thanks Ferdinand]
This Arc Reactor is a great re-creation of the fictional source of Iron Man’s power. It’s really just a holder for a bunch of LED’s, but it exhibits some fine craftsmanship which we enjoy in any project. This rendition is much more true to the movie than the last look-a-like we saw. These might end up being for sale (the webpage narrative is kind of weird) but you really shouldn’t be wearing this kind of thing around unless you made it yourself, or if you can add it to some kind of Iron Man simulator.
Researchers at Tokyo University of Agriculture and Technology have been demoing a new power suit. It’s intended to be used by people hand harvesting in the farm industry. The 55 pound device supports the worker’s joints as they squat and reach. Within three years, they hope to have the cost within $10K. We’ve seen quite a few power suit devices this year, but research has been going on for many years, as you can see in our power suit roundup.
