3D Printed Wave Lamp Forecasts The Weather

January 6, 2018 by 4 Comments

While browsing Thingiverse, [Dushyant Ahuja] found a rather pleasing wave lamp, and since a mere lamp on its own would not quite be enough, he added a means by which his lamp could provide weather alerts by means of changing its color.

It’s fair to say that the wave lamp is not a print for the faint-hearted, and it took him 30 hours to complete. However, it has the interesting feature of not requiring a support or raft. There is also a base for the lamp designed to take a strip of addressable LEDs, and he modified its design to mount a small PCB containing an ESP8266 module and a level shifter chip. The code for the ESP relies on the OpenWeatherMap API, and changes the LED color based on the rainfall forecast.

Casting our minds back a decade, this lamp is reminiscent of the long-departed Nabaztag product, best described as an internet-connected plastic anthropomorphic rabbit that could keep you updated with information such as weather or stock market trends through lighting up and the movement of its ears. It was an overpriced idea tied into a proprietary online back end that was probably well before its time back in 2004. Perhaps repackaged for 2017 with a commodity microcontroller board Nabaztag has finally found its application.

There is a short video showing the color change and an LED animation, which we’ve put below the break.

3D Printed Lamp Even Prints The Nuts And Bolts

October 10, 2017 by 13 Comments

The first print to come off a shiny new 3D printer is usually a toy widget of some sort that will forever sit at your desk without purpose. The alternative is a practical project that is custom and personal like this 3D Printed Articulating Lamp. [IgorF2] shares his design for this wall mounted device which was created using Fusion 360.

The complete design consists of eight parts which includes the arms, nuts, and bolts, as well as the wall mount, each of which can be printed individually. These come together to form a structure that can be attached to a wall or your work bench. Though [IgorF2] has provided arm pieces of length 100 mm, 140 mm and 200 mm, you can mix and match to create a much larger project. The files are available for download from Thingiverse for your making pleasure.

We think this can be a great basic structure for someone looking at custom wall mounted projects. The lamp mount can be easily supplemented by a Raspberry Pi and Camera holder if you feel like live streaming your bench. Alternatively, it may be customized to become a motion detecting lamp just for fun. We hope to see some good use come of it in the future.

A Crash Course In Thingiverse Customizer

June 27, 2017 by 19 Comments

OpenSCAD is a great way to create objects for 3D printing (or other purposes), especially if you are already used to programming. For things like front panels, it is great because you can easily make modifications and — if you wrote your code correctly–everything will just adjust itself to new positions.

However, what if you have a general-purpose piece of code, and you want people to have the ability to customize it? For example, consider this code:

$fn=100;
difference()
{
  cube([25,25,5]);
  translate([4,4,-1]) cylinder(h=7,r=2);
  translate([25-4,4,-1]) cylinder(h=7,r=2);
  translate([4,25-4,-1]) cylinder(h=7,r=2);
  translate([25-4,25-4,-1]) cylinder(h=7,r=2);
}

That creates the plate with four drill holes you see on the right.

Stop Printing Air With A Filament Sensor

March 4, 2017 by 21 Comments

If you have had a 3D printer for awhile, you know the heartbreak of coming in to check on an 8-hour print only to find that in hour 7 you ran out of filament (or the filament broke) and your printer has been dutifully moving around for no reason. [Chuck Hellebuyck] knows and he decided to make a filament sensor he found on Thingiverse.

Finding a part on Thingiverse and printing it probably doesn’t warrant much attention. But if you watch the video, below, it is a good example of how things from Thingiverse don’t always meet your needs. The microswitch [Chuck] had was bigger than the design used. So he loaded the STL file into TinkerCAD and fixed it. He shows you exactly how he did it. That’s a useful skill because you never know when you’ll need to modify some part you’ve found on the Internet.

Fully Printed CNC On An IKEA Table

February 2, 2016 by 15 Comments

It seems that many 3D printer owners just aren’t getting the same buzz they used to off their 3D printers, and are taking steps to procure heavier machines. And making them in their home laboratories with, you guessed it, their 3D printers.

Following the pattern, [Michael Reitter], designed a 3D printable CNC around a IKEA MALM table. In order to span the length of the table for his X axis, he came up with a very cool looking truss assembly. The linear rails rest on top of the truss, and a carriage with the Z axis rides on the assembly. The truss has enough space in the center of it to neatly house some of the wiring. The Y-xis mounts on the side of the table.

Overall the mechanical design looks pretty solid for what it is, with all the rails taking their moments in the right orientation. We also like the work-piece hold downs that slide along the edge of the table. It even has a vacuum attachment that comes in right at the milling bit.

We’re not certain how much plastic this build takes, but it looks to be a lot. Monetarily, it will probably weigh in at a bit more than some other options. As many in the 3D printing world are discovering, sometimes there’s no reason not to leverage more mature industrial processes for lower cost large gains in accuracy and strength. Though, it’s pretty clear that one of the design goals of this project was to see how much one can get away with just a 3D printer, and we certainly can’t deny the appealing aesthetic of this CNC.

Video of it in action after the break.

Fish Feeder

3D Printed Fish Feeder

February 27, 2015 by 16 Comments

[Helios Labs] recently published version two of their 3D printed fish feeder. The system is designed to feed their fish twice a day. The design consists of nine separate STL files and can be mounted to a planter hanging above a fish tank in an aquaponics system. It probably wouldn’t take much to modify the design to work with a regular fish tank, though.

The system is very simple. The unit is primarily a box, or hopper, that holds the fish food. Towards the bottom is a 3D printed auger. The auger is super glued to the gear of a servo. The 9g servo is small and comes with internal limiters that only allow it to rotate about 180 degrees. The servo must be opened up and the limiters must be removed in order to enable a full 360 degree rotation. The servo is controlled by an Arduino, which can be mounted directly to the 3D printed case. The auger is designed in such a way as to prevent the fish food from accidentally entering the electronics compartment.

You might think that this project would use a real-time clock chip, or possibly interface with a computer to keep the time. Instead, the code simply feeds the fish one time as soon as it’s plugged in. Then it uses the “delay” function in order to wait a set period of time before feeding the fish a second time. In the example code this is set to 28,800,000 milliseconds, or eight hours. After feeding the fish a second time, the delay function is called again in order to wait until the original starting time.

MRRF: Repables, The Nonprofit 3D Object Repository

Repables

There’s a problem with online repositories of 3D printable objects: The largest repo, Thingiverse, is generally looked down upon by the 3D printing community. Thingiverse, owned by Makerbot, has seen protests, and calls for a an alternative repository. A few people have stepped up to provide a better Thingiverse, but these alternatives are either connected to specific 3D printer manufacturers like Ultimaker’s YouMagine, or have done some shady things with open source licenses; Defense Distributed’s DEFCAD, for example.

Repables, launched at the Midwest RepRap Festival this last weekend, hopes to change that. They are the only repository of printable objects and design files out there that’s backed by its own nonprofit LLC. It’s free for anyone to upload their parts and share, without the baggage that comes with an ‘official [company name] .STL repo’.

Just about everything can be hosted on Repables – .STL files for printable objects, .DXF files for laser cutter files, and even PCB files and Gerbers for circuit boards. Now, .STL files are able to be rendered in the browser, with support for viewing other formats coming soon.

It’s a really great idea that solves the problem of printer manufactures building their own hosting sites and the segmentation that ensues. It’s also headed up by a Hackaday alumnus, []. We’re everywhere, it seems.
