World Maker Faire: 3D printed tower defense

Seej

Going to the World Maker Faire isn’t all fun and games; sometimes you have to suck it up, pay $130 in cab fare, buy $7 Heinekens, and crash the super not-so-secret after party.  While the company was fantastic, one of the more exciting interactions was [Jim Rodda]‘s Seej, a tower-defense-ish game constructed entirely of 3D printed weapons, flags, and blocks.

The goal of the game is simple: Each player gets a Seej engine, some blocks, a few pennies, and three flags. The first person to topple all three flags with ballistic pennies is declared the winner. The Seej engines aren’t just limited to the red and black catapults shown above; there are plans for a ballista available, and we’re sure someone will add a 3D printed trebuchet the the arsenal at some point. We’ve seen at least one example floating around the web.

In all honesty, this game is really fun and well worth the frustration experienced by a pitiable bartender who I hope was tipped well for the night.

World Maker Faire 2013: The Sub-$500 Deltaprintr

There are a few delta bot 3D printers out there such as the Rostock which, while being a very nice printer, is still a little expensive. When [Shai] from SUNY wanted to use a 3D printer for his artistic and academic pursuits, he decided to build his own printer. Thus the Deltaprintr was born.

Instead of printed parts, the Deltaprintr uses laser cut and machined parts for just about all of its bill of materials. The three motors mounted in the base are connected to the delta arms with Spectra fishing line, thus getting rid of the ludicrous cost of belts of the requisite length.

Everything is Open Source, and the guys behind the project should be putting their printr up on Kickstarter sometime next month. Word is the entire thing should be sub-$500, and a little bit of guessing tells me that doesn’t mean $499.

Pocket Sized Sattelites for Asteroid Detection

satellite

We’ve seen kicksats before, small pocketable single board satellites designed to orbit Earth. At this year’s Maker Faire, the team behind these kicksats has a new plan: using them to determine the orbits of earth-passing asteroids and hopefully not giving us any forewarning of our imminent extinction.

Instead of simply orbiting Earth, the new plan for these kicksats is to deploy them into the path of an oncoming asteroid such as Apophis so the radio transmissions from each satellite can pinpoint where exactly the asteroid is, something Earthbound optical and radio telescopes struggle with.

Despite the small size, the hardware on each kicksat is pretty impressive; each mini satellite has a solar cell on each side, a low-power MSP430 microcontroller with a radio module, and a few sensors. The system is designed so anyone can pick up the telemetry from these satellites with a small Yagi antenna and an RTL SDR TV tuner dongle.

An impressive bit of kit, but if holding a satellite or asteroid in your hand is more your thing, the same team behind the kicksat put up a whole bunch of 3D models of asteroids and space probes. They’re actually quite impressive when they’re printed out.

World Maker Faire: The New Ultimaker

Ult

Just as the the gates opened at the World Maker Faire in New York City the skies opened, sending everyone underneath the tents and pavilians on the faire grounds. Luckily, I was able to check out the new Ultimaker before that happened, and only a day after it was officially announced.

Compared to the older laser-cut Ultimaker, the Ultimaker 2 is much, much cleaner that’s made more for designers and architects instead of students, hackerspaces and tinkerers. There are a few new additions to the Ultimaker 2 – OLED display, heated bed, and a larger build volume. Basically, if you want Ultimaker quality without a lot of futzing around, go with the Ultimaker 2.

Ultimaker will be shipping a pre-assembled version for €1.895,00, with a kit version to follow shortly. As always, the Ultimaker 2 is open source, and no, this doesn’t mean an end to the classic Ultimaker.

Hackaday is going to the NYC Maker Faire!

maker

In just a few short days, the greatest hackers and makers from all around the globe will descend on the Hall of Science in New York City to show off their wares. Our new guy [Adam] and myself will also be there, giving these makers our unending support, putting up a few posts about what they built, and giving out some Hackaday swag.
