Quintuple-Sized LEGO Go-Kart

[Matt Denton] was inspired by [James Bruton]’s scaled up LEGO and decided to create his own giant LEGO project. He found a classic model that he wanted to scale up.  1985’s Technic Go-Kart (set #1972) contained 98 pieces and seemed manageable.

He wanted to create something his 8yo nephew [Ruben] could sit in, but had to rule out a fully kid-sized go-kart. It had also to be (at least somewhat) economical with regards to plastic and printing time. [Matt] settled on sizing the largest piece—the 2×8 plate—to fit diagonally on the 11”x11” bed of his Lulzbot Taz5.

It took 168 …read more

Electric LEGO Longboard Now Complete with Epic Road Test

We recently posted about [James Bruton]’s most excellent oversized LEGO electric longboard. Well, now he has completed the project by tidying a few things and building oversized versions of classic light-up bricks to serve as headlamps and the tail light. Most importantly, he’s hitting the road with it!

He built a LEGO-looking enclosure for the battery as well, based on a 2×6 brick. The battery pack sits behind the motor with the tail light on top and holds the radio control receiver as well the twin LiPos. The head and tail lights pack 24-LED discs and are controlled by [James]’ …read more

Monster Mindstorms Delta Bot Delicately Picks Candy

A group of embedded developers from Sioux Embedded Systems in Eindhoven, the Netherlands, wanted to get experience working on Microsoft .Net. To make it fun they made it their project to produce a LEGO train with visitors at LEGO World, the official LEGO convention in Denmark. The team developed an application in C# to fully automate the train, with Mindstorms NXT and EV3 bricks as well as LEGO Power Functions motors controlling everything.

The train project carries a simple premise: the visitor chooses one of four colors, and the train goes and picks up a piece of simulated candy with …read more

Electric Skateboard Rocks the Giant LEGO

[James Bruton] built an electric skateboard out of oversized LEGO bricks he printed himself, and equipped the board with an excellent re-creation of a classic motor.

He began by downloading brick, gear, and pulley designs from Thingiverse and printing them up five times their normal size, taking 600 hours. The deck consists of 8M Technic bricks lengthwise and 4M bricks crosswise, with plates covering top. There’s even a monster 5×6 plate that’s clearly courtesy of a parametric brick design because you won’t find that configuration among LEGO’s official parts.

The coolest part of the project is probably [James]’ re-creation of …read more

Mindstorms Morse Key Writes to Drawbot

[Jason Allemann] built a Mindstorms Telegraph Machine that packs so many cool details that HaD is about to have a fit.

First off, It’s a drawbot able to write letters, a difficult feat given a lack of native stepper motors and the limited gear options for Mindstorms.  Trying to draw letters with servos typically makes for some ugly letters. And how does the drawbot know what to write? You code them in with Morse code. The second video after the break shows [Jason]’s setup. He has a Mindstorms touch sensor with a LEGO Morse key attached to it. He simply …read more

We Dig This LEGO Excavator Conversion

[Frank] was lucky enough to score a bucket wheel excavator LEGO set as a birthday present, and we won’t lie – we’re jealous. However, out of the box, the kit is somewhat limited; there is only one motor to animate the entire machine and it can’t be fully remote controlled. But don’t worry — [Frank] set out to change that (Google Translation).

The first part of the build was to add motors to control the different functions of the excavator. One motor was added for each of the two tracks to allow the machine to drive forwards, backwards, and turn. …read more

Making Spirographs with LEGO and Math

Master LEGO builder [Yoshihito Isogawa] has been on a roll lately, cranking out a number of robots that make drawings reminiscent of the classic Spirograph toy. For instance, he built an elegant drawbot out of LEGO elements, seen above. At first glance the monicker “spirograph” seems wrong, because where are the gears? However, [Yoshihito] has them stashed underneath the sheet of paper, with magnets controlling the pens.

His drawbot consists of a platform (cleverly, an inverted LEGO plate) upon which a sheet of paper is laid. One or two pen holders, each with a pair of magnets underneath, rest on …read more

EV3DEV Lego Linux Updated

The ev3dev Linux distribution got an update this month. The distribution targets the Lego EV3 which is a CPU Lego provides to drive their Mindstorm robots. The new release includes the most recent kernel and updates from Debian 8.8. It also contains tools needed for some Wi-Fi dongles and other updates.

If you haven’t seen ev3dev before, it is quite simply Linux that boots on the EV3 hardware using an SD card. You don’t have to reflash the computer and if you want to return to stock, just take out the SD card. You can also use ev3dev on a …read more

Converting a Robotic Motor For Lego Blocks

The Internet has brought a lot of advantage to life, not the least of which is access to really cheap electronic parts. [KarelK166] was buying cheap geared motors for projects, but they didn’t easily work with Lego blocks. He found an easy way to adapt them and–lucky for us–decided to share.

The process is pretty simple. The gearbox has two screws and an elastic band holding it together. Once the gears are exposed, you can drill a hole in two of them with a 4.8mm drill bit. This might take a little practice since the gear needs to hold still, …read more

Chocolate Factory Simulation Makes Bars with LEGO

[Michael Brandl] got to visit the Milka chocolate factory in Bludenz, Austria and was inspired to build this simulation of the production process for the LEGO world 2017 event in Copenhagen.

The process begins with the empty mold riding on a double row of tank treads. Subsequent modules seem to fill the mold with LEGO ingredients, cool the bars, and remove them from the mold. The last two steps rock: [Michael] built a dispenser that drops a tiny cardboard box onto the line, sized to hold 3 LEGO bars. The box rolls to the end of the line and is …read more
