Alternative to Xtion 3D sensor?

Hi,

For my new robot I was planning to use popular Xtion depth sensor. Even got one. I am really like it because it is smaller than Kinnect, does net require separate power supply and well supported by OpenNI on Linux. Unfortunately, there are indications that it is discontinued by Asus.

Troubleshooting 3-d Printer

This blog is a place to collect notes to be worked up into a Tips post for trubleshooting 3-d Printer problyms.

The idea is to list a symptom with a photograph and list sucsful fix actions to try.

 


 

For Example:

Printer: Printerbot LC

Material: ABS

Notes: Extruder temp 230C, Bed temp 110C, Fan on 100%,Polymide (Kapton) on a glass bed 

Problym: Poorly formed vertical edges, Keystoning (wider at the top then the bottom)

Print your own CtC!

 

While I was at Maker Faire this year, I was booth-neighbors with the great Fredini who was 3d scanning folks the whole weekend. I was one of the luck folks to be scanned!

Control Blender3D objects remotely

I just made a very simple example using Zeroc's Ice which illustrates how to control Blender objects remotely using Ice. Since Blender can run Python scripts, the idea is to write Ice server which can modify certain object properties (for example location). Corresponding client application can remotely invoke server methods and control objects remotely. Sources are available on GitHub. The first video illustrates how it works.

NerdCam3D has arrived

Hi folks,

it really has been a while, my last post is months ago. But in the meantime I have made major progress. First of all I have bought an Axial Wraith, a RC-car that offers lots of hardpoints to mount and attach devices. Then some guy from the Geman FPV-community made a small GRP-case for the camera. In this way I was able to crawl through my backyard in FPV for the first time (see 1st attached video).

Cnc or 3D printer?

So, this is my problem: Which one should i buy? Tell me pros and cons, like price and complexity. Some of you have knowledgement with these things, and these guys know a lot of these things. But most importan thing: I need something affordable and it can be used to produce robot parts Thanks, BotFIN

PrintrBot

Hey LMR, 

Has anyone here got, or has heard about, the PrintrBots. I am thinking of buying one and I am just wondering about people's experiences with the company and the actual printer.

Some things I would really like to know are:

Is it worth the price? Is the liney effect that you get on prints really bad or can that be improved with tuning and experience? Can you make threads for screws accurately or is that a longshot?

Thanks Guys (and girls)

Displays the time in binary
Hi, this is a binary clock that I made for fun out of a Teensy 2.0, some 3mm leds, and RTC, and a 3D printed shell. It displays the current time(in 24-hour … Read more

First trials with new 3D-camera attached to Zeiss Cinemizer Plus

Hi there,

As I have announced in my last post this one is going to be on the first trials of my new 3D stereoscopic camera
module. But before we start let's first take a look on the hardware.

3d part printing problem

I have designed a part in OpenSCAD and also output an STL file, both attached at the bottom of this post. I tried printing at 40 to 60 mm/s the first time. Everything was good until it reached the "leg" proper. Once there, it offset the print by about half the thickness of the leg. Thinking speed might be an issue, I slowed it down to somewhere in the range of 10mm/s. I got similar results. The offset was less pronounced, but, still there and still making the part useless. Do any of you 3d printing guys have any ideas for me?

Steampunk printing

Some of you might already know that I’m absolutely in love with my Makerbot 3D printer. It has opened up a whole new world of ways to design and build stuff. My current project has a Steampunk theme and I needed some parts for decoration. So I fired up Sketchup and designed some parts that I think looks cool and printed them out. Printed them out and added some paint and now it feels like stuff from the Steampunk universe.
I’m especially happy with the handles.

Processing mapping project

Project verview: 

 

mapping system using serial comms and processing 

 

 

I can do the coding and datbase side of things, hardware will be dependant on everyones robots but i use arduino and plan to go n to a beagle board i nthe long run and Cris uses pic so we should be able to make this pretty portable for everyones projects.

 

At the moment im working on a nice GUI(Graphical User Interface) to make it easier to see whats happening and hopefully cut down on development time.

 

Ideas anyons time :D  

Google sketch-up: entering absolute coordinate

ok, i'm trying again with sketch up

now, i want to move an object to an exact location, x,y,z. not just moving it around with the mouse.

how do you do? i read the guide and it says something like entering [x',y',z'] on the value box, but i have a problem with this: for making the brakets [] i have to press the alt button, that automatically interrupts the command so i'm unable to move.

Also, how do you see the exact coordinates an object is ?

thanks
