Custom Bases Make LEGO Spacecraft Even Cooler

If you’re reading Hackaday, we’re willing to bet that you either own the LEGO Saturn V and Lunar Module models, or at the very least know somebody who does. Even if you thought you’d finally outgrown playing with little plastic bricks (a critical mistake, but one we’ll ignore for now), these two kits just have an undeniable appeal to them. You might never get a chance to work for NASA, but you can at least point to the Saturn V rocket hanging on your wall and say you built it yourself.

[Ben Brooks] thought these fantastic models deserved equally impressive stands, so he built “exhaust plumes” that both craft could proudly perch on. With the addition of some RGB LEDs and a Particle Photon to drive them, he added incredible lighting effects that really bring the display to life. There are also sound effects provided by an Adafruit Audio FX board, and for the Lander, an LCD display that mimics the Apollo Guidance Computer DSKY that astronauts used to safely navigate to the Moon and back.

In his write-up on Hackaday.io, [Ben] makes it clear that he was inspired by previous projects that added an illuminated column of smoke under the LEGO Saturn V, but we think his additions are more than worthy of praise. Playing real audio from the Apollo missions that’s synchronized to the light show honestly makes for a better display than we’ve seen in some museums, and he even rigged up a wireless link so that his neighbor’s kids can trigger a “launch” that they can watch from their window.

For the Lunar Module, he 3D printed an enclosure for the Photon and Adafruit quad alphanumeric display that stands in for the DSKY. There’s even lighted indicators for the 1201/1202 program alarms that popped up as Neil Armstrong and Buzz Aldrin descended to the lunar surface 50 years ago.

While many of us aren’t old enough to have our own first hand memories of the Moon landing, projects like this prove that the incredible accomplishments of the Apollo program never fail to inspire. Who knows? Those kids that are watching [Ben]’s Saturn V from next door might one day get to make the trip themselves.

Magnetic Attraction Of Microduino MCookie Modules

We’ve seen countless different robot kits promoted for STEM education, every one of which can perform the robotic “Hello World” task of line following. Many were in attendance at Maker Faire Bay Area 2019 toiling in their endless loops. Walking past one such display by Microduino, Inc. our attention was caught by a demonstration of their mCookie modules in action: installing a peripheral module took less than a second with a “click” of magnets finding each other.

Many Arduino projects draw from an ecosystem of Arduino shields. Following that established path, Microduino had offered tiny Arduino-compatible boards and peripherals which connected with pins and headers just like their full-sized counterparts. Unfortunately their tiny size also meant their risk of pin misalignment and corresponding damage would be higher as well. mCookie addresses this challenge by using pogo pins for electrical contacts, and magnets to ensure proper alignment. Now even children with not-quite-there-yet dexterity can assemble these modules, opening up a market to a younger audience.

Spring loaded electric connections are a popular choice for programming jigs, and we’ve seen them combined with magnets for ideas like modular keyboards, and there are also LittleBits for building simple circuits. When packaged with bright colorful LEGO-compatible plastic mounts, we have the foundation of an interesting option for introductory electronics and programming. Microduino’s focus at Maker Faire was promoting their Itty Bitty Buggy, which at $60 USD is a significantly more affordable entry point to intelligent LEGO creations than LEGO’s own $300 USD Mindstorm EV3. It’ll be interesting to see if these nifty mCookie modules will help Microduino differentiate themselves from other LEGO compatible electronic kits following a similar playbook.

Lego Goes Underwater, With Model Submarines And Missiles

It is fun to make a toy vehicle with Lego, but it is even more fun to make one that actually works. [PeterSripol] made two Lego submarines, and you can see them in the video below. There isn’t a lot of build information, but watching the subs fire missiles and then getting destroyed by depth charges is worth something.

One of the subs is larger and uses a rudder to steer. It was apparently harder to control than the other smaller sub which used two motors thrusting opposite one another to steer. Looks like fun.

The works of Shakespeare, Goethe, and Cervantes combined do not equal the genius of Rick And Morty. Actually, the word ‘genius’ is thrown around a bit too much these days. Rick and Morty has surpassed genius. This cartoon is sublime. It is beyond any art that could be created. Now, you might not have a high enough IQ to follow this, but Rick and Morty is, objectively, the best art that can be produced. It just draws upon so much; Rick’s drunken stammering is a cleverly hidden allusion to Dostoevsky’s Netochka Nezvanova, absolutely brilliantly providing the back-story to Rick’s character while never actually revealing anything. Now, you’re probably not smart enough to understand this, but Teenage Engineering is releasing a Rick and Morty Pocket Operator. Only the top percentages of IQs are going to understand this, but this is game-changing. Nothing like this has ever been done before.

The Microsoft IntelliMouse Explorer 3.0 is the high water mark of computer peripheral design. Originally released in 2003, the IntelliMouse Explorer 3.0 was an instant classic. The design is nearly two decades old, but it hasn’t aged a day. That said, mouse sensors have gotten better in the years since, and I believe the original tooling has long worn out. Production of the original IntelliMouse Explorer 3.0 stopped a long time ago. Microsoft tried to revive the IntelliMouse a few years ago using a ‘BlueTrack’ sensor that was ridiculed by the gaming community. Now Microsoft is reviving the IntelliMouse with a good sensor. The Pro IntelliMouse is on sale now for $60 USD.

It has come to my attention that wooden RFID cards exist. This shouldn’t come as a surprise to anyone because wood veneer exists, thin coils of wire exist, and glue exists. That said, if you’re looking for an RFID card you can throw in the laser cutter for engraving, or you just want that special, home-made touch, you can get a wooden RFID card.

Lego has just released an Apollo Lunar Lander set, number 10266. It’s 1087 pieces and costs $99. This is a full-scale (or minifig-scale, whatever) Apollo LEM, with an ascent module detachable from the descent module. Two minifigs fit comfortably inside. Previously, the only full-scale (or, again, minifig-scale) Apollo LEM set was 10029, a Lego Discovery kit from 2003 (original retail price $39.99). Set 10029 saw a limited release and has since become a collectible: the current value for a new kit is $336. The annualized ROI of Lego set 10029-1 is 13.69%, making this new Apollo LEM set a very attractive investment vehicle. I’m going to say this one more time: Lego sets, and especially minifigs, are one of the best long-term investments you can make.

A Weinermobile is for sale on Craigslist. Actually, it’s not, because this was just a prank posted by someone’s friends. Oh, I wish I had an Oscar Mayer Weinermobile.

Rumors are swirling that Apple will release a new Mac Pro at WWDC this week. Say what you will about Apple, but people who do audio and video really, really like Apple, and they need machines with fast processors and good graphics cards. Apple, unfortunately, doesn’t build that anymore. The last good expandable mac was the cheese grater tower, retired in 2013 for the trash can pro. Will Apple manage to build a machine that can hold a video card?  We’ll find out this week.

Lego is releasing a series of Braille bricks. As near as we can tell, these Braille bricks are standard 2 x 4 bricks, with studs corresponding to Braille letters on the top. There are also screen/pad printed legends on top. I don’t mean to be a downer, but why, exactly, is this being created now? Did it really take fifty years for someone to say, ‘hey, if you don’t put some studs on top of a brick, it becomes Braille?’ How is this not already a thing? This isn’t me being facetious — how did it take so long for this to be invented?

KiCon is this weekend, so here’s a tip for everyone in Chicago right now: get a hot dog. Don’t put ketchup on it, or else someone will shoot you.

KiCon and Moogfest in one weekend? Yes, and that means new toys. The Matriarch is Moog’s latest synthy boi and the apparent successor to last year’s Moog Grandmother. The Matriarch is a four-note paraphonic synth that is semi-modular; no, you don’t need patch cables to make noises, but there are ninety-odd patch points for modular fun. It’s two grand, which is getting up there in the synth game. If only Radio Shack were still around and sold Moog synths…

We’re all aware that Russia launches rockets out of Baikonur cosmodrome, and the first stages eventually make their way onto the steppes of Kazakhstan. The locals, few there are, end up recycling these rockets, scrapping them, and sometimes taking space tourists and photojournalist out to the crash site of these boosters. Russia has other spaceports, and now we’re getting pictures of booster crashes from the frozen north. These rockets came from the Plesetsk cosmodrome and fell in the boreal forests near Arkhangelsk where hunters discovered them. Yes, these boosters are carcinogenic, but that’s what you do when a few tons of aluminum and titanium fall in your backyard.

No spoilers, but oh man the after-credits scene in Endgame was hilarious.

Watch This LEGO Pantograph Carve Chocolate Messages

[Matthias Wandel] is best known for his deeply interesting woodworking projects, so you might be forgiven for not expecting this lovely chocolate-engraving pantograph made from LEGO. With it, he carves a delightful valentine’s message into a square of chocolate, but doesn’t stop there. He goes the extra mile to cut the chocolate carefully into a heart, and a quick hit with a heat gun takes the rough edges off for a crisp and polished end result.

The cutting end is a small blade stuck inside a LEGO piece, but that’s the only non-LEGO part in the whole assembly. A key to getting a good carve was to cool the chocolate before engraving, and you can see the whole process in the video embedded below.

Lego Monorail From Your 3D Printer

If you had to guess the age of a person hailing from a country in which Lego is commonly available, you might very well do it by asking them about the Lego trains available in their youth. Blue rails or grey rails, 4.5, 9, or 12 volt power, and even somewhat unexpectedly, one rail or two. If that last question surprises you we have to admit that we were also taken aback to discover that for a few years in the 1980s everybody’s favourite Danish plastic construction toy company produced a monorail system.

[Mike Rigsby] had a rather ambitious Christmas display to produce, and as part of it included a pair of reindeer, Rudolph and Bluedolph, atop freight cars on a loop of Lego monorail. He didn’t just use classic Lego parts off-the-shelf, instead he recreated the system in its entirety on his 3D printer; locomotive, rolling stock, and all. In a simlar way tot he original his locomotive sits between the two freight cars, each container housing a pair of AA batteries which together power the unit.

The Lego system isn’t perhaps a classic monorail, in that it involves a four-wheeled vehicle that is guided by a central rail rather than sitting upon it. Drive comes from teeth on the side of the rail which mesh with a gear on the power car. There have been 3D-printable sections of it available as add-ons for owners of classic sets for a while, but this may be the first printable locomotive and train. The Christmas novelty aspect of it all may be a little past its sell-by date here in February, but it’s still worth a look as a potential source of parts for any project that might require a linear rail system.

Perhaps surprisingly we’ve never featured a monorail before, though we have brought you a MagLev.
