Quintuple-Sized LEGO Go-Kart

August 25, 2017 by John Baichtal 16 Comments

[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 hours to print all 98 parts (some of them in a series of smaller pieces), 5 kilos total of filament at mostly 20% infill. The resulting car can be assembled and disassembled just like LEGO—no glue! The rack and pinion steering actually works and the Ninjaflex-tired wheels roll as one would expect. So, pretty much the same as the real model only five times bigger. The only non-LEGO components are threaded rods down the middle of his cross axles as well as the hose, just Neoprene hosing from a hardware store.

[Matt] is well-known to Hackaday readers, being one of the original BB-8 builders as well as co-creator of the Mantis walking robot. He’ll be on hand this weekend in Maker Faire Hannover to share this project, Mantis, and others. Continue reading “Quintuple-Sized LEGO Go-Kart” →

3D Printing A Daft Punk Helmet

September 6, 2014 by Matt Terndrup 6 Comments

Thanks to the awesome people over at Adafruit, you can now print your very own Daft Punk helmet! It is designed with a hollowed out shell and translucent material which allows for colorful LEDs to be inserted into the mask, which can light up just about any room. This makes the headset great for Maker Faire, household parties, and underground EDM raves.

The epic costume was inspired by the infamous electronic music duo from France who is known for hiding their identities behind intricate and complex masks. This version, however, is perfect for the Do-It-Youself builder on a budget assuming you have access to a Taz 3D printer through your hackerspace or a friend.

The entire helmet is 3D printed as one piece using a semi-transparent PLA filament with NeoPixel strips (144 pixel per meter) laid inside. It takes about 3 days to complete the printing job (assuming no errors arise during the process). After everything is finished, glossy gold paint is applied and the polished outcome is enough to turn some heads. Plus, this mask makes a great addition to any builder’s homemade ‘trophy’ collection.

A natural next step would be to add sensors that can detect bass vibrations. This could be used to change the colors of the display based on the music that is being played nearby. We’ve seen this sort of thing before on a few Daft Punk helmet builds that are far superior to this one. Of course the difference here is that the Adafruit version can be build in a reasonable amount of time by a mere mortal. Those other examples were life commitments as far as projects go!

Don’t forget to check out the video of this one in action after the break.

Get Your Hackerspace A 3D Printer

February 26, 2014 by Brian Benchoff 4 Comments

LulzBot is yet again giving away a few of their very fancy and well-reviewed 3D printers away to a few hackerspaces.

This isn’t the first time LulzBot has given away a few of their printers; a year and a half ago, they gave away eight AO-100 printers and they also donated one to our ‘ol buddy [Caleb] for TheControllerProject, a forum to connect disabled gamers to people who have the means and ability to make custom gaming controllers.

The rules for this giveaway are simple: Be a hackerspace, and display, “creativity and contributions to the free software and open hardware community.” It’s as simple as that. If you’re a hackerspace without a 3D printer – which would be somewhat astounding at this point – here’s your chance to get one of the best 3D printers around.

The contest will be open starting March 1 and ends on March 14, with entry requiring a hackerspace fill out a form somewhere on the LulzBot servers.
