LEGO Meets Nintendo Switch

Posted on by

As you probably know, the Nintendo Switch is the incredibly popular console of the moment. You of course also know that LEGO has been popular since the beginning of recorded history. So it was only a matter of time before somebody decided that these two titans of youthful entertainment needed to combine up like some kind of money-printing Voltron. You know, for science.

[Vimal Patel], a known master of all things plastic brick related, decided to take up the challenge with a few experimental LEGO accessories for the Switch. These add-ons are largely designed to make playing the Switch …read more

A Tabletop Star Wars Themed Lego Racer Game

Posted on by

When it comes to the title of undisputed king of the toy construction kit world, the Danes have it. Lego are ubiquitous in the toybox, and parents worldwide know the joy of stepping barefoot on a stray brick. Aside from the themed sets for youngsters and collectors, we see a lot of Lego in projects that make it to these pages. Sometimes they are from hardware hackers who’ve chosen Lego because they had some to hand or because of its utility, but at other times they come from the Lego community rather than the wider one.

Take the Star Racer …read more

MIT Makes Lego Lab For Microfluidics

Posted on by

As any good hacker (or scientist) knows, sometimes you find the tools you need in unexpected places. For one group of MIT scientists, that place is a box of Lego. Graduate student [Crystal Owens] was looking for new ways to make a cheap, simple microfluidics kit. This technique uses the flow of small amounts of liquid to do things like sort cells, test the purity of liquids and much more. The existing lab tools aren’t cheap, but [Crystal] realized that Lego could do the same thing. By cutting channels into the flat surface of a Lego brick with a precise …read more

LED Stand For Lego Saturn V Boldly Goes Where No Lego Has Gone Before

Posted on by

Hackers everywhere have spent the last couple of weeks building the remarkable Saturn V Lego models that they got for the holidays, but [Kat & Asa Miller] decided to go an extra step for realism: they built a stand with LED lights to simulate launch. To get the real feel of blast off, they used pillow stuffing, a clear acrylic tube and a string of NeoPixel LEDs. These are driven by an Adafruit Trinket running code that [Asa] wrote to create the look of a majestic Saturn V just lifting off the launchpad with the appropriate fire and fury.  They …read more

Connecting Cherry MX Key Switches To LEGO Just Got Easier

Posted on by

Here on Hackaday, we like keyboard hacks. Given how much time we all spend pounding away on them, they’re natural hacks to come up with. If you’re pulling the circuitry from an existing keyboard then chances are the keys are pressed either by pushing down on rubber domes (AKA the membrane type), or on mechanical switches. [Jason Allemann] has just made it easier to do keyboard hacks using LEGO by building one for a circuit board with mechanical Cherry MX key switches. That involved designing parts to connect LEGO bricks to the switches.

For those custom parts, he recruited his …read more

Solving a Rubik’s Cube with Just Two Motors

Posted on by

We’ve all seen videos of Rubik’s cube champions who can solve the puzzle in less than 5 seconds. And there are cube-twisting robots that can solve the cube even faster, often in under a second. This Rubik’s cube solver is not one of those robots, but it’s still pretty cool.

The reason we like Dexter Industries’ “BricKuber” is not for its lightning speed — it takes a minute or two to solve the puzzle. What we like is the simplicity of the approach to manipulating the cube. Built from LEGO parts, including Mindstorms motors and a BrickPi controller, the BricKuber …read more

Lego Go-Kart Scores Radio Control

Posted on by

LEGO has always been an excellent toy for both play and learning, and the Technic sets are a great starting point for any budding engineer. Not content to rest on their plastic, blocky laurels, LEGO introduced more advanced parts over the years, such as motors and battery packs to allow builders to propel their creations. Combine this mechanical philosophy with [Matt]’s Giant Lego Go-Kart and you have one heck of a project.

It all started months ago, when [Matt] built his original Giant Lego Go-Kart, a 5-times scaled up model of the original kit #1972-1. Achieved through the wonder of …read more

Functioning Technic SLJ900 Bridge Builder

Posted on by

There is definitely a passion for detail and accuracy among LEGO builders who re-create recognizable real-world elements such as specific car models and famous buildings. However, Technic builders take it to a level the regular AFOLs cannot: Not only must their model look like the original, it has to function the same way. Case in point, [Wolf Zipp]’s version of a massive bridge-building rig. The Chinese-built SLJ900 rolls along the tops of bridges and adds ginormous concrete spans with the aplomb found only in sped-up YouTube videos. It is nevertheless a badass robot and a worthy target for Technicization.

[Wolf]’s …read more

Mechanical Marvel Trades Courage for Chocolate

Posted on by

When we see what [Jason Allemann] does with LEGO, we wonder why more one-offs aren’t made this way. This time he’s made a Halloween mechanical marvel that will surely scare more kids than anything else they’ll encounter on their rounds — so much so that many may even decline the chocolate it dispenses. Who wouldn’t when to get it you have to reach over an animatronic skeleton hand that may grab you while a similarly mechanized spider may lunge onto your hand.

The chocolate dispensing, the hand and the spider are all animated using four motors, a LEGO Mindstorms EV3 …read more
