OpenSkan – Hardware, software, and website updates!!

After OpenSkan got a lot of attention (thank you Make, Adafruit, and Hackaday!) I felt the need to update a lot of things. I had some poor quality videos, pics, and hardware out there. Since then things have changed a lot! Just check it out at OpenSkan.Org ! Lots of new Vids!

Hardware Changes

The platform frame is made of metal extrusions with 3D printed feet and a printed handle. The platform plate is now made of several laser cut layers, this makes the inner gear a lot stronger. Added a motor with higher torque and speed with a bigger 3D printed gear.

The column is a lot smoother running. Its also now made with the same aluminum extrusions rather than u-channel. This has added portability!  Also a few more printed odds and ends here and there. The center of the column where it connects to the legs is printed and adjustable.

Sensor and Software Changes

Marcos Garciaacosta from Intel was kind enough to give me an ivy bridge motherboard and processor. This coupled with a new Nvidia GTX 650 ti and a fancy new mini itx case makes for a really decent scanning computer. Especially since I now have a Carmine 1.09 scanning sensor from Primesense. I’ve even strayed away from reconstrustme and now have a license for Skanect, which after recent updates is amazing for 3D scanning!

 

Anyway, check out the new site www.openskan.org , find Open Skan on facebook and twitter. Thanks!

(If any of my work inspires you, please let me know, I’d love to see what you have!)

 

 

OpenSkan: Open Source Full Body 3D Scanner

Its no secret what I’ve been working on in my free time this year. I’m proud to say, after neglecting it for awhile, I’ve completed a functioning prototype for the OpenSkan full body scanning rig. I do say prototype, because I have a few parts to strengthen and replace, but as far as form and function, its there. I’ve got plenty of pics and a video posted after the break showing all the inner workings, a friend being scanned, and some prints.

 

As it stands now, I’m controlling the linear column and rotating platform manually through changeover switches, in a project box enclosure that I gutted from an old robot I made to teach students. Unfortunately I bricked my Arduino, so once that gets re-programmed I’ll have the column running with speed control for smoother scans and full automation.

So far I’ve managed to keep the costs low. Everything you see is either lasercut, 3D printed, or cut on a bandsaw. Once I work out the kinks I’ll be posting all the files. There are some pics, in the photoset below, that show some of the 3D printed assemblies, including a nifty winch I’m proud of. Keep in mind however, I modeled most of these more recent parts in 10 minutes or less.

Right now I’m using Reconstructme to acquire the scans through the kinect. I’ll be switching software as soon as I get a full license of Skanect, since its pricey for a broke University student. I also hope to get my hands on an Asus Xtion.

What does the future hold?

The platform is going to be strengthened and given a makeover with a fancy LED lighting system. The column will be replaced with two 4ft pieces of 1 X 1 t-slot extrusion and given added strength and stability. I’ll be bringing this bad boy out to some local events to build some interest (and some funds for more research). There are also some more OpenSkan products in the works, so keep your eyes peeled!

One more thing to note! A proper OpenSkan website is in the works. We’ll be creating a one stop place for information and plans on any and all types of open source homebrew scanning equipment.

OpenSkan Full Body 3D scanner nearly done

 

 

 

 

 

 

 

 

 

As many of you know (mostly from my previous posts) I’ve been putting together a full body scanner. Well, I actually got it built over a month ago, just haven’t gotten around to posting about it. Now I say its built, but I have yet to wire and program it for automation.

My goal with this is to make an elegant and cost effective solution for 3D scanning and printing. My next stage after wiring is to take it out to local events. I bit the bullet and bought a Replicator 2, so that I can have a high turnout rate. Future plans involve incorporating scans into digital avatars for use with Occulus Rift and Leapmotion.
