3D Printing From An Android Device

March 10, 2012 by Brian Benchoff 5 Comments

[skullkey] over at the House4Hack hackerspace in Pretoria, South Africa wanted a way to get kids excited about technology and desktop fabrication labs. Wanting to give kids a visceral feel for the march of technology, he created Makerdroid, an android app that allows for the creation 3D objects on an Android tablet and preparing them to be printed on a Reprap or Makerbot.

What’s really interesting about this build is not only the fact that [skullkey] and his lovely beta testers are generating .STL files on an Android device, the object files are also being converted to GCode on the Android, without the need for a conventional computer. Makerdroid uses the very popular Skeinforge to generate the instructions for the printer (although a lot of people are switching over to Slic3r).

Makerdroid doesn’t need a PC to print objects out on a 3D printer, but we think the process of shuffling GCode files from a tablet to the printer with an SD card is a little archaic. It might be possible to print directly from an Android tablet over Bluetooth with the Android Bluetooth Reprap app that is currently in development. Still, we love the idea of printing objects we just created on a touch screen, as shown in the Makerdroid demo video after the break.

Huge, fully functional NES game pad replica

huge_nes_pad

Students at Dutch TU Delft university recently built a huge replica of the original NES controller (Google Translation), which is fully functional and can be used to play games on a large display screen they also installed. How big is it, you ask? It’s about 6 meters wide – over 30 times the size of the original NES game pad and requires participants to jump on the buttons to play.

Convert any image to G-code

bitmap_to_gcode

Members of [Forskningsavdelningen], a Swedish hackerspace, are working on software that will allow users to vectorize bitmap images in order to convert them to G-code files for CNC milling. A good portion of the project is complete, but there is still a bit of work to do, so you won’t see it in action for a while. When it’s ready, we’ll be sure to let you know.

Convert your lame Dead Space plasma cutter into a bonafide laser weapon

If you forked out big bucks for the special edition of Dead Space 2, you know how lame the included plasma cutter replica is. Check out this video, that shows you how to convert your LED toy to a dual laser, fire starting, laser pistol. The process is pretty simple, so what are you waiting for?

Synchronized, LED-lit juggling balls

[Jonathan] wrote in to share a project he and some friends have just finished. He’s not sharing a ton of details at the moment, but he has put up a video showing off their wireless LED juggling balls. All we know is that they use bright RGB LEDS, Zigbees for communication, and that they are awesome. We can’t wait to hear more about them!

Water cooled PS3 Laptop

[Pirate] recently unveiled his latest work, a water-cooled Playstation 3 laptop. It looks pretty sharp, and can undoubtedly rival some of Ben Heck’s work, even if it does have an external PSU. Obviously having a separate power component isn’t necessarily ideal, but when you are cramming all of that water cooling goodness into such a small package, something has to give!

PartKAM Produces CAM Related Files Online

June 2, 2010 by Mike Szczys 6 Comments

PartKAM is a Flash-based CAM production package created by [Jack Qiao]. There are a ton of computer aided manufacturing suites out there, this one is simple and requires nothing more than having your browser open. We played with it for a few moments and found it useful but still a bit buggy. Most notably, it lacks a ‘undo’ option. That being said, you can export as SVG or gCode for use when you just need to hammer out a few parts with that CNC mill you threw together.

Generating G-code With Common Lisp

gcode

Ruin & Wesen are a two person shop creating specialized music gear. As part of their recent MIDI Command development, they got into case manufacturing. They purchased a mini CNC mill to cut the aluminum cases. Unhappy with the software options provide [Wesen] decided to write his own G-code generator. G-code is part of the numerical control used to command CNC machines. He implemented his interpreter using the language he’s most familiar with: Common Lisp (not surprising if you notice the website’s backend). The post covers the design philosophy used and some of the problems that came up. We look forward to future releases since the interpreter can generate milling code using processing.org sketches and cut PCBs directly from Eagle.

You may remember Ruin & Wesen from when they shared their Eagle layout videos.
