[Daniel] was looking for a special gift to make for his close friend. His friend is a huge fan of the Myst franchise which made the decision easy — why not make a Myst Linking Book?
After doing some research he discovered that the book in the game footage was a Harper’s New Monthly Magazine, Volume LIV, Issue 312 from 1877. He attempted to find one on eBay but they were pretty expensive — and in pretty rough shape. So instead he settled on a copy of Scribner’s Monthly Magazine,Volume XL, Nov 1875 to Apr 1876. Not quite identical but close enough!
His original plan was to embed a Raspberry Pi with an LCD screen to show off the Myst videos, but then discovered the cheap and easy to use video greeting card modules, which you can pick up for $10-20 from China. They typically let you store about five videos and use a magnetic reed switch to activate — almost like it was designed for this project!

The massive engineering-defying Helicarrier from the Avengers is a brilliant work of CGI. Too bad it’d never actually fly… Like… Never.
Luckily, that didn’t stop our favorite RC hackers over at FliteTest from making a scale model of it — that actually works! If you’re not familiar, the Helicarrier is a fictional ship, the pride of S.H.I.E.L.D’s air force, or is it their navy.
It’s a massive aircraft carrier with four huge repulsor engines built into it, borrowing tech from Stark Industries. The shear size of it is what makes it completely ridiculous, but at the same time, it’s also unbelievably awesome.
Unfortunately, repulsor technology doesn’t seem to exist yet, so the FliteTest crew had to settle with a set of 8 brushless outrunner motors, with two per “engine”. The whole thing is almost 6′ long.
It doesn’t handle that well (not surprising!) but they were able to launch another RC plane off of it, mid-flight! Landing however… well you’ll have to watch the video. Continue reading “Lego Avengers Assemble to the Helicarrier!”
While researching copper plating graphite for a project, [Dave] stumbled upon a blog post illustrating a brilliant approach to metal plating 3D printed parts.
Our pioneers in this new technique are [Aaron], who runs a jewelry business, and [Bryan], a professor of Digital Media. By mixing graphite powder into an acetone solution, it is possible to make a kind of graphite paint that sticks extremely well to ABS plastic.
Using the graphite painted part as the cathode, and a chunk of copper as the anode, it becomes possible to electroplate the part with a variety of electro-forming solutions. In the first test (seen above), [Bryan] uses a Midas Bright Electro-forming Copper Solution (copper sulfate solution).

One of our tipsters stumbled across a pretty impressive video of a giant Tesla coil playing music — in a snowy forest! The forum showing off the video is in Finnish but Google Translate does a pretty good job getting the point across.
This massive Tesla coil dubbed the BiggerDR was built by [Kizmo], who lives way up north in Finland. He was originally inspired by another build and decided to try his hand at making one. The Tesla coil, detailed in another forum post (in English this time) has some pretty impressive specs. The coil alone has 1550 wraps! Not too mention a pretty impressive bank of capacitors in series…
His YouTube channel has some great videos of the build — in fact, he’s been messing around with Tesla coils for at least 7 years already — stick around after the break to see BiggerDR in action.

We’ve all heard the terrible greeting cards that have soundbites of 2 bit jingles that usually make you want to tear the battery out… but Hallmark is finally catching up with technology and now including real music in their cards — it might only be about 10 seconds, but hey, it’s a step!
They’re still pretty corny though, and we’re not really sure what even dictates an ideal situation to give someone an audible greeting card — but regardless, [Dmitry Grinberg] thought he could do better than Hallmark — and we’d have to agree. He’s created a New Year’s Greeting card using a CD jewel case, and what he’s packed inside is pretty incredible.
The case, when opened, will play a full-length song in full fidelity. Next time you open it, it’ll play something new and at random, from its very own micro SD card 300-song library.

Many think that the next big step in 3D printing is when we’ll be able to print in metal, well, at an affordable rate. But what about printing in metal and plastic at the same time?
The thing is, most electronics are typically two-dimensional. Layers upon layers of relatively flat PCBs make up the brains of every bit of technology we know and love. The funny thing is, we live in a three-dimensional world, and we like to shove these flat circuits into three-dimensional boxes. Well, what if we didn’t have to? What if the circuit could be embedded directly into whatever shape we want? It’d be pretty awesome — minus the whole servicing aspect of the product…
Anyway we’ve seen some great hacks over the years attempting this, like adding a copper wire strand into your 3D print, embedding components into your print by pausing the job, or even going old school and using the point-to-point Manhattan style circuit construction to add some electronic features to your part. But what if your printer could do it for you?
That’s exactly what Optomec is attempting with the Voxel8 3D printing electronics platform. It is your standard run of the mill FDM style 3D printer, but it has a 2nd extruder that is capable of squeezing out liquid silver ink that dries at room temperature. Just take a look at this quadrotor they were able to make.

Well, we have to admit, we never saw this coming… A 3D printed lawn mower? What? Why? Huh? How? Those were at least a few of the thoughts running through our head when we saw this come in on the tips line.
[Hans Fouche] has a giant 3D printer that takes up most of the space in his garage, and after printing several large vases, a briefcase, bowls, and even a wind turbine blade — he decided to try printing a lawnmower. A freaking lawnmower.
To do so, he reverse engineered his old rusty lawn mower, and redesigned it to be printable. Apart from the steel axles, some fastening hardware, and of course the motor and blade, the entire thing is 3D printed. And it looks like it works pretty good too.
