Make your own 3d printed DIY chorded keyboard

Chorded keyboard is a computer keyboard where you get characters by pressing several keys at the same time.
This input method should improve speed, make your keyboard one hand usable, smaller and mobile or just make you look like ultra cool elite hax0r.

There are many different projects and now there is a Chordy KEY project with 3d printable case.

Chordy KEY combinations. Well, there is a learning curve if you want to be cool ...

GitHub repostiory with all the details and STL files:

https://github.com/Madfellows/Arduino/tree/master/Chording%20keyboard

From project description:

Chording keyboards have been around for a while, but appear to not be taken seriously. Although you can see many data entry methods throughout science fiction but usually involve hundreds of buttons that require the user to look at them and appear to be hard to work in adverse conditions or with bulk such as gloves.

The chording keyboard can take on many different shapes and easily used with one hand. The keys can be easily acquired without the use of pips and build with proper spacing to be used with gloves. The lower amount of keys used makes the manufacturing of the device cheaper and simpler.

This project is a completed left hand proof of concept chording keyboard that currently has all functionality of a standard keyboard minus function keys and plenty of combinations to add them and many macros. The base microcontroller is a ATmega32U4 packaged as a sparkfun pro micro, 8 buttons and 6 indicating leds the case is 3d printed and backed with craft foam.

How to make printable 3d models from complex datasets of water and sewage systems

Scott Kildall has several projects involving complex data sets processing and transforming them into 3d printable objects for information visualization.
He made and interesting tutorial on how to make 3d printable data crystals and now he published two tutorials on how to make 3d printable models that are three dimensional maps made from geospatial data of complex sewer and water city systems.
How to guides are treasure if you are into 3d visualization of complex data sets and map making.

Here are links to Instructables tutorials with detailed workflow ans software used. The entire process is not too complex and can be done even if you are novice:

WirePrint wireframe 3d printable models for faster prototyping by Hasso Plattner Institute and Cornell University

Researchers from Hasso Plattner Institute and Cornell University developed WirePrint software for faster prototyping. It basically custs down the time needed to 3d print an object by replacing solid volumes with wire frames.

A question comes to my mind: if this is publicly funded institute will the release the code under one of open source license? Public money should provide public with some tangible goods and services ...
I don't know much about how this sort of institution operates, gets funding and disseminates knowledge form applied research ...

Update: here is some sort of similar code on GitHub, inspired but not related to this project but creates wire frames:

https://github.com/ramkam/wireframe_3d

From video description:

WirePrint is a low-fi fabrication technique that prints 3D models as wireframe previews. By extruding filament directly into 3D space instead of printing layer-wise, we achieve a speed-up of up to 10x compared to traditional 3D printing.

This project is a collaboration between Hasso Plattner Institute and Cornell University.

PETG 3d printing filament

PETG is a 3d printing filament made from PET-G which is Glycol-modified PET, the modification is done by adding a second glycol during polymerization.
The resulting molecular structure is irregular and the resin is clear and amorphous with a glass transition temperature of 88 C (190 F).
Filament made from it gives good combination of toughness, clarity and stiffness

More about PET-G:
http://en.wikipedia.org/wiki/Polyethylene_terephthalate

Here are videos from Mihai Oltean showing actual 3d printing with PETG and object properties:

Here are links to his blogposts about his PETG experiences with more details:

http://3d-printizer.com/blog/?p=258

From his experience PETG doesn't stick to blue tape or to cool glass printbed.

Detailed post about testing strength of PLA vs. PETG printed objects:

http://3d-printizer.com/blog/?p=268

Looks like PETG doesn't break but bends at much higher weight loads then PLA which breaks relativity easy.

Cerberus Gigante big Delta 3d printer made by Steve Graber

Large custom Deltas seem to be very popular recently. Here is a new Ceberus Gigante 3d printer made by Steve Graber and used by artist Kevin Caron to make big sculptures. It is made out of CNC cut aluminum. It can 3d print 34" in diameter and 4'6" in height (metric is superior guys) and uses 3 mm filament (that's better).
Nice work Steve!

RepRapPro just release Ormerod 2 3d printer which features many improvements over the first version and the lower price.

Oremerod 2 tech specs:

Full open-source self-replicating RepRap
New 32-bit Arduino-compatible Duet electronics enable control via a web-browser
Wiring loom for simple plug-in connection – no soldering
IR probing for self-aligned printing – no bed adjustment required
Build volume: 200x200x200mm
Overall size: 500x460x410mm
Weight: 6 Kg
Printing materials: ABS, PLA, 1.75mm diameter thermoplastic.
Build surface: PCB-heated bed to reduce complexity of assembly and to ensure parts do not warp.
Computer interfaces: USB and Ethernet
X-carriage: Three Z-adjustable deposition head mounts; one head supplied
Motion: Linear ball bearings on X, Y and Z axes.
Pre-soldered electronics with built-in microSD card slot for standalone printing.
Enhancements to the printed parts to improve the ease of assembly of the X and Y axes

There are many improvements over first Ormerod 3d printer:

The Y carriage belt location and retention are improved by using printed parts rather than the laser-cut parts. This makes for easier belt tension adjustment.

The Y motor is now the same way round as the other two axes, which means that the Y axis can be zeroed more simply (previously the axis was designed with a high-end stop switch).

The heated bed support is a three-point support which makes bed level adjustment easier.

The infra-red Z/Bed probe is now differential, meaning that readings are taken with the IR LED on and then subtracted from readings with it off. This gives much less interference from ambient light and it is more accurate.

The extruder has much better access for cleaning and it has a locked drive stack that improves reliability.

The power supply is for worldwide universal voltage and is integrated into the machine compactly so there is no power distribution PCB needed, and there are no trailing wires other than the mains lead and the communications.

There are better integrated and simpler wiring looms, so still no soldering, but even easier wiring assembly.

There is an improved web interface, and you get even higher quality prints from better motion control. (All the new software is backwards compatible with Ormerod 1 so Ormerod 1 owners benefit from that too.)

There is simpler assembly and the build instructions are even more detailed.

Ormerod 2 is priced at £449 plus VAT (if applicable) for the full kit and £389 plus VAT (if applicable) for the the hardware only kits.

Press release:

... the origins of 3d printing are mysterious ... also, there was no Play-Doh in my country when I was a child (yes yes, the socialist darkness) and I have never seen it in real life (maybe it is similar to stuff we call "plastelin") ... ah well, I'll just believe the random internet meme ...

DIY ultrasonic distance sensor and tape measure by Adafruit

And it comes in 3d printed enclosure resembling fictional weapons from Dune universe.

If you don't know what Dune is or are unfamiliar with Weirding Modules, you should really do some reading and movie watching. The design is based on Beast Rabans pistol. Those DAMN Harkonnens ... I can only wish that Adafruit makes something Atreides or Fremen based ... just to bring more balance ...

As all Adafruit projects it comes with detailed instructions and documentation.

If you want to build one or learn more about ultrasonic distance measuring go to:

The cheapest automatic print bed leveling system made by Josef Prusa

Josef Prusa made an innovative ultra-low cost automatic printbed leveling mechanism for his RepRap.
It is made out of two glass plates and four micro switches (one in each corner) activated by printhead pressure.
The setup costs some 20 cents, so it is probably the easiest to make and cheapest system around.
Only limitations are that the switches get pressed if you print an object heavier then 300 grams and that you are limited in using heated bed.

Pi Top homepage: http://www.pi-top.com/

Reddit thread where they presented their 3d printed prototype:

http://www.reddit.com/r/3Dprinting/comments/2g0opb/fullsized_3d_printed_laptop_prototype_pitop_print/

They used the following setup:

Printer used: Rostock Max V2 kit - with E3D full metal hotend
Filament: PLA 1.75mm nozzle: 205 Bed temp: 55 Speed: 70mm/sec
Print time: 3 prints total (two pieces together and the two larger pieces seprately) roughly 160 hours of printing
Support settings: KISSlicer with medium support, at 45 Degrees with a horizontal gap (from object) of 1mm.
De-string Settings: Prime 5.5mm Suck: 5.4mm Wipe:5mm Z-lift: 1mm
Notes from the creators: "PLA really keeps its shape well. We had to use floating beams in the STLs to achieve a rigid enough support structure so the model wouldn't wobble after 10 inches tall and ruin the print. We found KISSlicer worked the best in terms of support structure."

Desert 3d printing in Morroco with WASP clay Delta

WASP from Italy is making some big Deltas that 3d print in clay mixtures. Here is a video of them in deserts of Morroco exploring some traditional earth construction buildings and clay mixtures. They make a traditional construction mix from local materials and use it in their machine to make some pottery or construction elements. In the future they will probably enlarge their Delta and 3d print entire homes.

I live in a house that is almost 100 years old and it's made from clay / earth sun dried bricks mixed with hay. Walls are almost one meter thick and it is very well insulated. I would like more application of old techniques in the future. Concrete boxes are just boring and sterile.

Acrylonitrile Styrene Acrylate filament from Stratasys

Acrylonitrile Styrene Acrylate or ASA is a new FDM filament from Stratasys which is very strong and UV resistant. Could it replace ABS?

ASA is an all-purpose material used for the production of prototypes, manufacturing tools and finished products. Manufacturers in the automotive, electronics, commercial, sporting goods and construction industries will benefit from ASA’s strength and durability. Applications include jigs and fixtures, electrical boxes, recreational vehicles and outdoor tools

Compatible with the Fortus 360mc, 400mc and 900mc 3D Production Systems, ASA thermoplastic surpasses the capabilities of ABS, offering UV resistance so parts will be durable and resist fading even with long-term exposure to direct sunlight. Considered to have the best aesthetics of any FDM material available, ASA offers an exceptional surface finish - details such as printed text and other features are greatly improved by ASA’s matte finish.

I wonder will this new type of filament come to DIY machines...

Here is the tech specs PDF sheet:

How to make 3d printable functional Pip-Boy 3000

Christopher Hoffman made this working Pip-Boy 3000 he will wear at DragonCon 2014. If you don't know what a PipBoy is, stop reading this post.

It uses 3d printed hand bracelet and embedded smartphone with external battery as an interactive display. I like it.
It is printed in 15 pieces and the print job takes some 25 hours. Well worth it.

It looks like the source model is developed by Yvo de Haas, the same guy who developed Plan B powder 3d printer.

How to make servo powered 3d printed valves for air or fluid flow control

Mikey77 known for several projects like the conductive printed electronic circuits posted his new work on 3d printable servo powered valves. The PLA printed valve can be used to menage air or fluid flow for any purpose you need it, the electronics are easy to put together and are controlled by Arduino or Picaxe. Servos used in this project are Futaba S3110 micro-servos.

Here is the 3d printed valve controlling the 3d printed robot muscle with air pressure

From project description:

The 3D printed valve is actually two valves that are controlled by one micro servo. When the cam (gray) is rotated to center, both valves are closed. From there, either one can be turned on, one at a time. The cam followers (black) push on the silicone tubing to compress it and create simple pinch valves.

The servo is quite efficient in that it is about the same volume of two 12 volt solenoid valves that handle the same pressure. It works efficiently at 20 PSI of air pressure and it has been tested at up to 30 PSI. It has also been motion tested and after more than 4300 on-off cycles it did not show significant signs of wear on the moving parts.

It is also considerably lighter than two solenoid valves and uses much less energy to operate. Once actuated, the valves can be left open or closed without using power.

Detailed construction guide, electronic schematics and files can be found at:
