If you look around Thingiverse, you'll find that most of the popular and non-decorative stuff is designed in OpenSCAD. To the original question, MakerGear makes some high quality kits.

No, John Carmack is developing software for the Oculus RIFT being developed by Palmer Luckey. http://oculusvr.com/?page_id=2 It is a pretty amazing piece of hardware though. Over 90 degree field of view for $500, rather than the $10000+

Even by press release standards, that release is vapid. Searching for Leap Motion reveals a web site equally devoid of information about what Leap Motion does and why we should care about its apparently new 3D motion-control tech.

It probably depends on how the button is debounced as well. Software and physical debounces are both generally tuned for at least a few milliseconds and potentially over ten milliseconds of latency. A better trigger could be built by inter

Ah, it seems prices have nearly doubled since the last time I bought from there. MakerGear had a similar price increase, and Rick posted a notice: " 4/9/12 - Please note that we have experienced a significant increase in pricing from our

As far as I can tell, there aren't any closeup pictures or videos of actual prints on the Cubify website. The images all appear to be renders. That should be a good clue as to the print quality. I saw them in action at CES, and the qualit

They aren't competing with RepRap so much as Makerbot, who ship an assembled "just works" open source printer and who are behind Thingiverse.

I'm excited to see what happens here. 3D Systems is releasing a printer with a proprietary filament cartridge[0], proprietary interface, and commercial ecosystem of downloadable solid model files[1] into a world that has inexpensive commod

It's actually pretty simple to hand solder a TQFP by drag soldering. The key is to use plenty of flux and have solder braid handy to take care of any bridges. http://www.youtube.com/watch?feature=player_detailpage&v... It's sort of

Consumer partially transparent head mounted displays are sort of available. SiliconMicroDisplay has one that is bulky and not really transparent enough to walk around in, but could be used to approximate Project Glass: http://www.siliconm

That is DSL, where they are limited by the length and quality of the pieces of copper connecting the CO or RT to your modem. Their 100mbit and gigabit services are fiber to the home.

That's not really a vicious circle. People not knowing you shouldn't prevent you from trying to do something. Do something cool and show it to an online community related to whatever you did, or even Hacker News or Reddit if it has general

Nicholas C. Lewis posted a decent open source inkjet[0] on Thingiverse. He had a Kickstarter for his inkjet cartridge controller[1], which I later used for something silly[2]. 0: http://www.thingiverse.com/thing:8542 1: http://nicholasc

It's to take up the rest of the space in the 3D render. In seriousness, it is an interesting idea by some designers who presumably either didn't understand or didn't care why their imagined implementation was silly or wouldn't work.

It's what is happening now because that is where the interest for home 3D printing is and what the capabilities of those printers are. 3D printing is popular among the maker crowd, and the printers are mostly capable of doing relatively lo

I have a 3d printer in my bedroom. I don't think one could reasonably run a 5 axis mill inside a house or apartment. Another issue is raw material. For a mill, you need to keep around various sizes and shapes to subtract from. With addit

This isn't really about printing a car, in the short term at least. This is a response to the kinds of DMCA takedown notices that Thingiverse has been getting lately, on Warhammer figurine models for example. http://groups.google.com/grou

If you examine the .lfp file, it shows that it stores a set of 1080x1080 JPEGs representing different images planes in the light field along with their depths. There is also a 25x25 look up table of the depth levels of the image, presumabl

Physically , you're stuck at f/2 in the sense that that is the actual f-stop of the lens. The information exists to let you choose the focus and the depth of field of the desired display image after capturing the light field. This simpli

There are already several significantly more powerful ARM Cortex-M3 boards available for around the price of an Arduino[0][1]. The draw of the Arduino is ease of use in interfacing to GPIO/UART/i2c and in the community of accessories, docu

3D printers are a reality, but $600 3D printers that are low maintenance and come assembled and ready to go are certainly not. I don't see anything on the Origo site suggesting they've solved the problems that have kept the UP!, the assembl

I wonder if that was related to their acquisition of Voodoo. Perhaps the original Envy was a case of putting an HP badge on a Voodoo design, whereas the later designs were from HP Personal Systems Group.
