The first time I saw 3D modeling and 3D printing used practically was at a hack day event. We printed simple plastic struts to hold a couple of spring-loaded wires apart. Nothing revolutionary as far as parts go but it was the moment I realized the value of a printer.
Since then, I have used OpenSCAD because that is what I saw the first time but the intuitiveness of other programs led me to develop the OpenVectorKB which allowed the ubiquitous vectors in OpenSCAD to be changed at will while keeping the parametric qualities of the program, and even leveraging them.
All three values in a vector, X, Y, and Z, are modified by twisting encoder knobs. The device acts as a keyboard to
- select the relevant value
- replace it with an updated value
- refresh the display
- move the cursor back to the starting point
There is no software to install and it runs off a Teensy-LC so reprogramming it for other programs is possible in any program where rotary encoders may be useful. Additional modes include a mouse, arrow keys, Audacity editing controls, and VLC time searching.
Here’s an article in favor of OpenSCAD and here’s one against it. This article does a good job of explaining OpenSCAD.

[Aldric Negrier] is no stranger to the 3D printing world. Having built a few already, he designed and built an SLA/DLP 3D printer, named RooBee One, sharing the plans on Instructables. He also published tons of other stuff, like a 3D Printed Syringe Pump Rack and a 3D Scanning Rig And DIY Turntable. It’s really worth while going through his whole Instructables repository.
This open-source 3D printer was inspired by the Cristelia – SLA/LCD 3d printer and the Vulcanus MAX 3D printer (that he designed). RooBee One has an aluminium frame and an adjustable print area of 80x60x200 mm, with up to 150x105x200mm build volume using an ACER DLP projector. In addition, a fan on top of the printer was added to extract the toxic vapours outside and away from the printer operator. The electronics are based on the Arduino MEGA with the RAMPS 1.4 shield and one NEMA 17 stepper motor. As for the Arduino Mega firmware, [Aldric] choose to use Repetier, which he usually uses in his other printers.
The SLA resin he used is the Standard Blend Resin from Fun to Do Resins. These resins tend to release toxic airborne particles, so extra care should be taken to ventilate the area while printing and also do a proper cleaning afterwards.
You can get a glimpse of the printer making a small gear come to life in the following video:

The Spherebot is an open source machine capable of printing designs onto spherical objects, such as Xmas baubles!
The design is based on the ever-popular Egg-Bot, which we have seen derived into many other useful printers such as the Mug Plotter, and the Ping Pong Printer.
The Spherebot features two stepper motors, one servo motor for marker actuation, some cheap mounting hardware, and a whole bunch of 3D printed parts—all of which are available on Thingiverse. In this design they used a 3D printer controller board called the 3Drag by Open-Electronics, which is based on the ATmega2560 (the same microcontroller as the Arduino MEGA). The Spherebot doesn’t require all three axes or an extruder, so they only installed 2 out of the 4 stepper drivers on the board to save cost.
Once you have it all built, it’s a simple matter of uploading your design into the free Spherebot-Host-GUI provided on GitHub. Stick around after the break to see just what it is capable of!

When the Bristlebots were released back in 2007 by Evil Mad Scientist Laboratories, we all thought they were pretty cool. Apparently someone at Klutz did too. They have released a book, with the title “Invasion of the BristleBots”. The bots seem to be identical and the name is identical. There is no mention of Evil Mad Scientist Laboratories anywhere in it. [Phillip Torrone] has attempted to contact Klutz and the book publisher Scholastic directly to find out more information.
[Windell] and [Lenore] from EMSL had this to say:
“This is the first that I’ve heard of it. Frankly, I am a bit offended. Klutz makes some nice things, and I’m surprised that they wouldn’t have contacted us, asked permission, or at least given us credit. (Locomotion by ratcheting bristles isn’t remotely new — it occurs in nature — but the name ‘Bristlebot’ is surely ours, and I don’t know of any prior implementation with a toothbrush.)”
You probably know EMSL from their other projects such as the Peggy and Meggy jr. How would you feel if a project you did was published without credit? Would you care or not?
While Muxtape takes a breather to resolve an issue with the RIAA, Lifehacker has a step by step guide on installing and running Opentape, an open source PHP web application that’s similar to Muxtape. Take matters into your own hands and create your own version of playlist hosting heaven. Since Opentape is open source, you can adapt it and make it an even better application. Maybe your creation will be even more popular than Muxtape… and will lead to the same problems with the RIAA.
Adeona is an open source internet-based laptop tracking system that is free to use. It’s available for Linux, OSX, and Windows XP/Vista. After installation, Adeona will submit at random intervals, anonymously encrypted updates on the computer’s location to servers on the Internet, specifically to OpenDHT, a free storage service. The information is kept on the servers for one week. If your laptop becomes lost or stolen, you can use the retrieval tool to access information about where your laptop was last used: the external IP address, internal IP address, and nearby routers. If your laptop is a Mac, you can also download isightcapture to grab a picture of the thief. Adeona is designed to protect against common criminals who may not have much technological knowledge, and does not have any protections against events such as disk wipes. The open source nature of Adeona’s system means that there’s ample opportunity to improve upon the release or add extensions. Here’s one user who really likes what he sees.
The Nokia N810 tablet is a great buy, especially for hackers. It already ships with a Linux-based operating system, called OS2008, which is based upon Maemo 4.0. However, for those who aren’t fans of OS2008, you can install Debian easily with some patience and an extra memory card. The Debian install includes OpenOffice, Firefox 3, AbiWord, and IceWM. You should be aware that there are pitfalls. Some of the applications run slowly, and you may be in danger of losing data if you run into problems.
