Semi-autonomous 14-DOF quadrupeds using Mini Maestro
Ryan 
Customer Lujing Cen’s team built two semi-autonomous 14-DOF quadrupeds using Mini Maestros for their high school class project at the California Academy of Mathematics and Science. The project syllabus includes making two separate robot designs and three total robots that work together. These quadrupeds were the “pack robots” described in the syllabus. An 18-channel Mini Maestro USB servo controller controls the twelve leg and two head servos. The project code includes a rewrite of Pololu’s Maestro C# USB SDK library in Python. The robot uses a camera and an RFID scanner to track its targets. 










Tinha alguém de pensar nisto, e os bacanos da Universidade do Arizona, e da Pensivânia, pensaram, então, porque não imprimir em Metal com estruturas de suporte solúvies, com n Impressão 3D de Plástico?
E foi o que fizeram:






Metal 3D Printing is About to Get Faster Thanks to Dissolving Supports
Hanna Watkin

An assistant professor at Arizona State University has developed a method of printing dissolvable metal support structures. This breakthrough could make end-to-end metal printing faster.
Metal 3D printing is fast on its way to becoming a mainstay option for heavy duty industrial 3D printing. But, it can be a laborious process involving copious amounts of post-processing.
However, an assistant professor of 3D Nanofabrication at Arizona State University (ASU) might have a solution. The man behind this development is Owen Hildreth., who has a mechanical engineering degree and Ph.D. in nanofabrication materials engineering.
However, he didn’t turn his mind to it until dropping in on a talk by visiting professor, Timothy Simpson, who posed: “If anyone knows of a water-soluble metal we could use for metal AM support structures, talk to me afterwards.”
Simpson is a research professor at Pennsylvania State University’s Center for Innovative Materials Processing through Direct Digital Deposition.

Vintage Motorcycle Seat Restoration - CB200
bekathwia  
This Instructable is about creating a new seat for my motorcycle, a 1975 Honda CB200T.
I picked up a trashed old seat on eBay because my current seat is in good condition, and there's no sense in tearing apart a perfectly good seat. Plus then I wouldn't be making my bike inoperable while working on this project.
The main reason I wanted to change my seat is to lower standover height, since I'm extra short. I also welcomed the opportunity to customize any aspect of my bike, since I am a motorcycle beginner.

Make Your Own High Quality CO2 Lasercutter! With Touch Control!MichielD99 
Hello everybody
About a year ago, I wanted to buy a CO2 lasercutter to make my workspace complete. One problem was that lasercutters aren't cheap, especially not for hobbyists who want a large cutting area. Of course, for that price you also get awesome software and customer support when you buy a lasercutter, but I only turned 17 when I started this project and I just didn't have that money. That is why I built my own machine. I had already made a machine like this, so I thought: "Why not do it again?". Of course this one wouldn't be made out of MDF sheets.
I made this machine together with my friend Thibo as it was our integrated project for school (we are in our last year of industrial sciences). He focussed on the research about lasers and cutting with a laser, because it's amazing that you can cut objects just by using light. I focussed on building this machine. In this instruction, there will only be talked about the lasercutter itself. This is a full step by step instruction on how to build your own lasercutter! I've included every file you need for building it in this instructable.

Man Creates a 3D Printer for Under $75 - And you can too!Monica Aderholt  
It was just last week that we saw the cheapest assembled 3D printer become available to consumers around the world. That was when New Matter’s MOD-t 3D printer launched their Crowdfunding Campaign. Priced at $149 for the first 500 backers, $199 for the next 500, and $249 for the rest, it proved that 3D printers could be cheap enough for most consumers to at least consider purchasing.
One man, by the name of Tarkun Gelstronic has taken this a step further. He put himself out on a mission to create a 3D printer for less than $100. What he came up with was really quite amazing.  Gelstronic didn’t just want to create any 3D printer that he could; he wanted to create a quality 3D printer that could print in multiple materials and include a heat bed.

Cheap 3D Printer Pops Out Parts With Blazingly Fast Speed
James Mulroy 
The ORD BOT is a simple 3D printer platform kit that uses an extruder to "print" 3D objects, just like the Cube or the MakerBot. However, unlike the MakerBot, the ORD BOT can only print using one color at a time (for now, anyway). But what it lacks in color it gains in speed: Its print speeds exceed 400mm per second and can reach up to a whopping 1 meter per second. This is considerably faster than the MakerBot's output speed of 33mm per second. The ORD BOT comes with two different print areas with the largest, called the Hadron, being about 200 square milimeters.
Now the ORD BOT isn't for just anyone--it's made with serious makers and DIYers in mind. This platform kit is just that--a platform: You have to provide your own electronics and build the whole thing from scratch (this does make it highly customizable and flexible), but according to a spokesperson at the ORD BOT booth you can order one with the electronics included for about another $200.

D Printer - Working Area 40x40x40cm
Thomas Workshop 
Hello everyone, in this project I want to show you how to make a 3D Printer.
I always wanted to have a diy 3d printer. The easiest way to make it is print frame parts and coonnect it with aluminium profiles or somethink like that. But I didn't have acces to any 3d printer. So, I used my cnc machine to make all nessesery parts and when 3d printer was almost assembled I printed plastic parts whitch were hard or imposible to make on cnc machine. And now i have a 3d printer with working area around 40x40x40 cm :)
I made a video and step by step instruction how to make it.

Four Whistles Version 2gzumwalt 
Four Whistles Version 2 is my first attempt at a "calliope" (well, sort of calliope) design utilizing the primitive knowledge I gained from the original Four Whistles Instructable (https://www.instructables.com/id/Four-Whistles/). Not being a musician and being "slightly more than hard" at hearing, while it may not sound like it this model is attempting to play "Mary Had A Little Lamb" using a balloon to power the whistles and a hand crank to power a cylindrical sequencer.
In order to play "Mary Had A Little Lamb", I incorporated four whistles in the design of this model, each controlled by one of four air valves. Each of the air valves are controlled by a rotating cylinder containing small 2.5mm "bumps" that activate the valves in the correct sequence (the "cylinder sequencer"). In order to minimize air loss and maximize play time, I designed the valves with a 3 degree preload (to increase the compression of the valve gaskets on the valve body valve plates), designed the valve "axles" using a virtually airtight membrane with torsion bars, and as a last defense against air leaks, used clear silicon caulk to seal the valve body assembly (see below). The caulk is not necessary, but will assist in producing a marked improvement in the models performance.

Gauss gun, and a 3D Freebie! Sim, uma Ideia e um Ficheiro 3D grátis!

Ora cá vai uma maneira de melhorar as Gauss Gun, esses Brinquedos Magnéticos que pareciam que já tinham tudo pensado...
Mas não!
Um Íman de Neodímio, é um Íman muito frágil, se for forte, a sua própria força o vai destruír, mais tarde ou mais cedo...
È, ainda por cima, preciso pegar na esfera de trás, depois de se ter disparado, colocá-la à frente, e só assim se pode re-começar.
Esta versão, ideia minha, pemite-vos disparar, mover uma esfera para a frente, disparar, até se fartarem.
E não partem o Íman. 

Mas, como se isso não fosse o suficiente, podem, ou fazer a coisa em casa, ou mandar imprimir em 3D:








Repetition Gauss Gun
Edgar

Gauss guns, those roller bearing ball shooting magnetic toys, fun as they are, suffer from the limitation of having to re-configure all the elements for each shot.

And, too strong Neodymium magnets may be destroyed by those hardened steel spheres, because they are directly impacted.

Not good.

So this is my solution, first, the magnet is out of line with the balls, and second, the balls have a no-return latch, so, all you have to do, to re-set the thing, is to move the balls forward.

Neat, huh? :)


And the Latch uses a small steel or iron part, a bolt, etc. in that hole, there, so you don't need to add any spring to keep the latch down, see the second picture:

Don't want to make it?

You can have it 3D printed:

Imprimir A CORES, na vossa Impressora! E o Zero Terninal, tricotar a 3D(!), um Sistema de Segurança Pi, e rodízios retractáveis!

Uma das tais ideias que são simples...
Mas só DEPOIS de se lá chegar!
Dica de Helga Pushkina:
Imprimir a cores, multi-materiais, numa só cabeça de Impressão, sim, sem mais do que uma Cabeça de Impressão, com a Impressora que já compraram?

Fácil... 
Se se cortar, e enviar, por sequência, de N Bobimas de filamentos diferentes, uma série de segmentos, conforme a impressão decorre!
Tempo para levar a mão à testa e dizer, "porque é que eu não pensei nisto?"










Palette takes up to four filaments and combines them into a single filament strand. This strand is then fed to your printer, enabling your one extruder printer to create multi-filament prints! 

HOW IT WORKS

  • Drive: Palette’s all-metal drive systems, inspired by those on industrial FDM machines, accurately controls filament to ensure the right lengths are driven from each input.
  • Cut: A rotary cutter system slices filament to ensure a clean, low-resistance cut, time after time.
  • Connect: Palette’s patent-pending splicing system connects filaments together end-to-end before passing them through a machined Teflon channel and splicing them together.
  • Cool: Combining both active and passive cooling systems, your newly spliced filament is re-hardened to ensure it keeps tight dimensions before being passed to your printer.
  • Calibrate: Our patent-pending synchronization systems continually monitor and adjust for filament usage, allowing Palette to modify filament lengths to ensure perfect calibration over thousands of feet.

Zero Terminal is a Tiny Linux PC in a 3D Printed Case
Bulent Yusuf 
The Raspberry Pi Zero W is a computer with wifi and Bluetooth that’s the size of a stick of gum. It’s cheap, cheerful, and staggeringly significant in democratizing computing. But you still need to hook it up to a monitor and keyboard to make use of it.
Enter the Zero Terminal, created by a mysterious character known only as “Node”. This homemade project combines the Pi Zero W with a slide-out QWERTY keyboard, touchscreen display, and a 3D printed shell. The result? A small, all-in-one computer that’s both portable and usable.
The PC runs stock Raspbian, which is a Linux operating system for the Raspberry Pi. The limited processing power of the Zero W means operations like running a web browser are slower than molasses. For basic tasks like working in the command line, meanwhile, or even word processing and running games in an emulator, the Zero Terminal should be adequate.

Mais uma ideia insólita, tricotar em 3D!
Porque pode tricotar em CNC, de forma a imprimir uma Camisola, por exemplo, e não só linearmente.

Ready-to-knit meets ready-to-wear: Kniterate is the new 3D printer for knitwear
Julia

Kniterate, the 3D printer for Knitwear, has taken Kickstarter by storm with its new crowd-funding campaign. The digital knitting machine, which first crossed our radar back in June 2016, has recently resurfaced, catching the eye of design bloggers, knitters, and knitwear enthusiasts alike. And all the buzz may be just what Kniterate needs to hit the market: with almost $250,000 already pledged, the Kickstarter campaign has more than doubled its initial goal of $100,000.

R-PiAlerts: Build a WiFi Based Security System With Raspberry Pis

imjasonc  
While working at your desk, suddenly you hear a distant noise. Did someone just come home? My car is parked in front of my house, did someone break into my car? Don't you wish you got notification on your phone or at your desk so you can decide whether or not to investigate? Well question no more! R-PiAlerts is here!
What is R-PiAlerts?
R-PiAlerts is a Raspberry Pi3 based security system built around Firebase's Cloud. If movement is detected, the system will notify the user of a potential break-in with a text message and a blinking LED display (silent visual alarm of sorts). Once user receives a notification, he or she can investigate. All detected movement will be logged to the Firebase database. Besides viewing the movement log on a web browser, the user can also access the movement log via an iOS app. I decided to build this due to the recent rise in break-ins to both vehicles and homes around my area. 









...E termina-se com este Projecto, que vos permite construírem os vosso próprios rodízios retractáveis, para mesas que podem re-colocar em qualquer parte, mas que ficam fixas, quando no sítio que querem, mas também podem apreciar um pouco da metodologia que este nosso amigo usa para fazer estas e outras Engenhocas:

Single Cylinder Air Engine
gzumwalt 
Before starting with this Instructable, I would like to express my sincere thanks to Instructables for featuring Single Cylinder Air Engine. I am indeed honored and humbled, again, many thanks.
Single Cylinder Air Engine runs on compressed air, a vacuum cleaner, a balloon, or even lung power. I've included three adapters in the design to interface with each. Please note the friction test video; your engine needs to pass this test before being successfully operated on balloon power.
The design incorporates two ports, one upper and one lower. When Single Cylinder Air Engine is viewed from the port side, "Wheel Piston.stl" rotates clockwise when pressure is applied to the upper port, and counter clockwise when a vacuum is applied to the upper port. As pressure or vacuum is applied to the upper port, the lower port functions as an exhaust (when pressure is applied) or an intake (when vacuum is applied). The opposite occurs when the lower port is used for pressure or vacuum.

MakerBot says its new print process reduces times and costs by around 30 percent

Brian Heater  
MakerBot’s MinFill arrived quietly last night as a firmware upgrade for existing customers, and the company is already calling it a “big benchmark in speed and widespread adoption of 3D printing.” Many are understandably a bit cautious around such grandiose proclamations from players in this space, particularly when it comes to something as unabashedly unsexy as infill — the support structures inside a model that keep it from collapsing.
At a bare minimum, however, the newly released MinFill setting boasts some potentially impressive numbers. The technology, designed in-house for the company’s Print software, runs an algorithm that determines the minimal amount of material required to create sufficient infill for a model, saving on material and print costs — both major sticking points in the technology’s adoption.
“You can imagine as you print a complex shape, you get a lot of interesting internal geometries that support the shape in the right places,” the company’s VP of Engineering Dave Veisz tells TechCrunch. “The net effect is that it’s going to reduce the amount of filament used and reduce the print time. So, you’re printing less to get your finished product.”
The time and cost savings varies, naturally, from project to project, owing much to different sizes and shapes of objects, but Veisz says the savings to both average out around 30 percent, effectively cutting the amount of material required to print an object by nearly one-third. Really geometrically complex objects, on the other hand, can have savings of upwards of 80 to 90 percent.

Mechanical Xylophoneneilmendoz 
This Instructable will actually show you how to make a mechanical glockenspiel as the keys are metal rather than wood (xylophone is a far better word though featuring very underused letter X). This instrument was a part of The Rock Band, composed of instruments that make music with rocks by throwing them through the air, slapping them and making them vibrate. The project was created at Autodesk's awesome Pier 9 digital fabrication workshop as part of their artist in residence program.
The rock parts of this instrument are the small pebbles that are launched at the keys. However, any small hard object would probably work. The aluminium keys were fabricated using a water jet cutter. If that tool is not available to you, then wooden keys could be used instead provided that the rest of the design is updated to accommodate their design. The xylophone will be controlled by MIDI so it is possible to control it to using most common music composition software, e.g. Logic, Cubase or Ableton.

The Easiest Arduino High Altitude Balloon Data Logger

Spaceshark 
High Altitude balloons are effective tools in conducting experiments and measuring data in the stratosphere. A successful launch can cost less than $200 and give insight and video of how our planet functions.
For hundreds of years, humans believed the Earth to be flat. High altitude weather balloons prove the Earth is in fact round. The idea of high altitude balloons or HABs is to mount a payload on a giant helium balloon. The balloons are then released, flying to heights of 100,000 feet. Once at these altitudes, the balloon pops and uses a parachute to float back to the ground often many miles from where it was first launched. HABs are great vehicles to get footage from the stratosphere, conduct science experiments, and collect data from high elevations.

3D Printer Buyers Guide

Alastair Jennings 
Frustrated with Fused Filament Fabrication? Read our 3D printing troubleshooting guide to the most common 3D printing problems and their solutions.
It’s amazing what your 3D printer can produce. But we’ve all had those infuriating moments when, despite everything, a seemingly simple model just refuses to print successfully.
You’ve checked the model, seen countless others make it without issue, but try as you might it just won’t print. What is it that keeps going wrong?
Here at ALL3DP, we’ve had our fair share of print failures. But the upside to those failures is that we’ve become finely tuned to recognizing and solving many common 3D printing problems.
