Designing a 3D Printable R/C Aircraft (Thin Walled, Lightweight Printing)

sahevaantaneja 

About two years or so ago, videos about 3D printed R/C aircrafts popped up on my suggested YouTube feed and since then I've wanted to build one of my own. I managed to find plans online and was intrigued by the immense amount of detail given to the internal structure, unfortunately, I did not have access to a paid slicer software capable of slicing such complex internal structures and the free slicer I was using was capable of slicing only the external skin/structure.
I figured that I might as well print the aircraft files I found online with conventional infills (hex, triangle, line, 3D gyroids etc.), a feature available with almost any slicer software out there. My printed aircraft turned out to be twice the anticipated weight and had a terribly high wing loading which made it fast as rocket.

E com este Instuctable, fazem um instrumento musical,  com uma gama de sons infinita, por obra do controlador MIDI, que faz dele um sintecizador, e depois um instrumento:

The Synthfonio - a Musical Instrument for EveryoneFrancoMolina
What this is 

This is an easy to learn instrument, simple to operate, improvisation oriented and with an endless possibility of sounds (as a MIDI controller). It features 2 sets of keys, one to define chords and key signatures, and another one to actually play the notes. Whatever chord is pressed in the instruments neck keys will define the pitch of the keys on the instrument handle, similar to a guitar, violin, and other string instruments; with the added advance that this one is a smart device that can interpret the scale being played from a single notes or pair of notes.

Spring Making / Wire Bending Machine 

jiripraus

Well, this machine is not only about making springs. It is a wire bending machine capable of bending 0.8/0.9/1 mm wire into any 2D shape. But yeah, the coolest thing I was able to make with it so far was the spring. How cool is that?
The main goal was to make it quite precise. Other DIY wire bending machines are not very precise and their bends tend to have quite a big radius. I like to work with nice sharp bends!
The second goal was to make it as easy to build as possible with commonly available parts and components. All the structural parts are 3D printed and all the metal parts are available in most of the hardware stores.

How to Create a Large 3D Printer Using a Smaller 3D Printer - "Project Locus"redhatman  

From those that own 3D printers, to those who simply are just curious about their capabilities, one topic that comes up rather frequently is the idea of "Printing another 3D Printer". Now this may not be 100% possible when considering components such as the electronics, however, nearly every 3D printer today in the open source community utilizes to some degree, 3D printed parts in it's construction. From fan mounts to spool holders, a person can spend a few minutes searching the web, and likely find a suitable design to use on their own printer. This has proved to be very useful, especially for those who love to build, modify, and design their own machines.

Que tal uma Micro-Fresa para a Oficina, para metais mais macios como Alumínio e Bronze?
Faz jeito:

Benchtop Micro Milling MachineHonus  

This is a micro sized benchtop mill that is suitable for milling small parts in soft metals such as Aluminum and Brass. While it is a manual mill it wouldn't be too difficult to convert it to CNC by adding suitable stepper motors and a CNC controller. 

The travel specs are:
X axis- 150 mm
Y axis- 75 mm
Z axis- 150 mm 

This design uses off the shelf assembled linear slides and 80/20 Aluminum extrusion for simple assembly and accurate alignment. The beauty of this design is its modular nature- you can make it any size you want and it's super easy to build.
Be sure to check out the build notes on all of the enlarged images!

Building the cheapest possible Prusa i3 MK2
Tom

What is the cheapest possible, real 3D printer you can buy without making one compromise after the other? That’s the question we’re asking by building a Prusa i3 MK2-style 3D printer that comes with most of the important features of the original one from Josef Prusa and requires a bit more work for sourcing and building the machine, but most importantly, we’re going to build it only with the most affordable set of parts.
This page will serve as a hub for part lists and build guides as the project moves along! All build videos and the accompanying project videos have been organized into a neat playlist!

Recreating an Antique Divers Helmet From Foam
LostWax

I love the ocean. I can sit on the beach all day just watching the waves do their wavey thing. Sadly, I happen to live in the middle of the Canadian prairies. No ocean to watch here. But there's always the world of make-believe, and what better way to get in the ocean vibe than with an amazing deep sea diver costume. I created this costume pattern to try and recreate the feel of the classic "Mark V" dive helmet which has become an iconic image of divers and the sea. It was used by the U.S. Navy from 1916 until 1984! Let's make one of our own.

Cardboard Bender
nml235l

A tool is something that makes life easier and more convenient. I have got a rather huge mass of cardboard (a cause of a new furnishings :-)) and appropriate number of ideas to make something with it (Bag for Containers). One problem is bend operations. Cardboard plates have a multiply layer (as usual) so I get clumsy splits during bending. To prevent such behavior I decided to flatten cardboard according the bend line. At this moment we get situation for a ... NEW TOOL. How to make flattening along the path? Certainly, using a one of the ancient inventions – the Wheel. We need only move the wheel (roller) along the path on cardboard surface with giving insignificant pressure. This principle we use in home preservation to connect bank and cover (or let's remember about the roller-machine for road construction). Concept of a tool is very simple: roller (wheel) and handle – nothing more.

This is a video about making a remote controlled forklift car. I've used Fusion 360 to design and create the 3D printed parts and CNC machining templates. If you don't have a CNC machine you can also use a jigsaw to cut out the wooden parts. I've provided the cutting templates, sources and 3D printing STL files on my GitHub page:

RF Signal Generator
Milen

The RF signal generator is a must to have tool when playing with radio receivers. It is used to tune a resonant circuits and adjust the gain of different RF stages. Very useful feature of the RF Signal generator is its modulation capability. If it can modulate the frequency amplitude or frequency makes it non replaceable tool for RF design works.
Some time ago I have designed an AM modulator, which could be used for such purposes. It works fine in some cases, but it has the disadvantage to be not able to work as standalone device. It requires additionally power supply module and two signal generators - for the RF carrier frequency and for the modulating signal. This makes it inconvenient to work with it outside the house. I decided to create an RF signal generator working as fully functional stand alone device. Instead to base the architecture on the modern DDS chip, I decided to use the analog approach. As a basis I have chose an existing RF signal generator published here. Similar design is described also here. The credits for this design go to their authors. I repeated mainly the first design adding additional digital frequency counter instead the not very precisely radial scale analog calibration.

Six Shot Blowgun

Edgar Castelo

3D model description
A Blowgun with a revolver's cylinder, 6 shots in rapid succession. It uses 20 mm PVC tubing, and it's just 4 pieces and a rubber ban, all easy to print and assemble.

Some 3 and a half hours to print, 98*44*30 mm, the larger part.The rest is the PVC tubing;
One large PVC tube part is the barrel, and 6 smaller tube parts, along with 2 other printed parts, make the cylinder.
The last 2 are a Rubber band, and the cylinder holding piece, that holds the cylinder, but rotates.

Designer Develops 3D Printer That Spits Out Wet Paper Pulp

Tyler Koslow

Designer Beer Holthuis has developed the Paper Pulp Printer: a 3D printer that squirts out fascinating objects made from wet paper pulp. The project aims to give artists and designers a way to 3D print more sustainable objects.
3D printing is a marvelous and innovative technology that enables us to create even the most complex designs, but one issue that has concerned environmentally-minded makers is the excessive use of plastic materials. Sustainability is becoming a major focus for many 3D printing companies and enthusiasts, leading to the development of recycled materials and other more earth-friendly processes.
Taking inspiration from the mischevious kids that sat in the back of class shooting spitballs at one another, designer Beer Holthuis has developed the Paper Pulp Printer: a 3D printer that extrudes sopping wet paper. Using a bit of natural binder and wet paper, the designer created a 3D printer that could extrude a thick bead of pulp that could be built up layer-by-layer into a 3D object.

Pessoal da Robótica, e Tele-controle, aprendam umas coisas sobre os Drivers, que impelem os Servo-motores a fazer o que lhes mandam:

556 Servo Driver
hombremagnetico

Servos (also RC servos) are small, cheap, mass-produced servomotors used for radio control and small-scale robotics. The are designed to be easily controlled: the position of the internal potentiometer is continually compared to the commanded position from the control device (i.e., the radio control). Any difference gives rise to an error signal in the appropriate direction, which drives the electric motor either forwards or backwards, and moving the shaft to the commanded position. When the servo reaches this position, the error signal reduces and then becomes zero, at which point the servo stops moving.
Radio control servos are connected through a standard three-wire connection: two wires for a DC power supply and one for control, carrying a pulse-width modulation (PWM) signal. The standard voltage is 4.8 V DC, however 6 V and 12 V is also used on a few servos. The control signal is a digital PWM signal with a 50 Hz frame rate. Within each 20 ms timeframe, an active-high digital pulse controls the position. The pulse nominally ranges from 1.0 ms to 2.0 ms with 1.5 ms always being center of range

$99 palm-sized PocketMaker 3D printer launches on Indiegogo 

While 3D printers do honestly come in all shapes and sizes, the vast majority of models feature roughly the same desktop size – with size differences usually being negligible. While the dream is always to go bigger and wider to facilitate larger prints and more ambitious projects, there’s a lot to be said for downsizing as well. Aside from the obvious benefit of making your 3D printer extremely portable, it also means 3D printing smaller, more efficient objects and optimally using your build volume. Why be tempted to go bigger if smaller means becoming more efficient? If this sounds appealing, then the palm-sized PocketMaker might be something for you.

Raspberry Pi Surveillance Rover (Land Drone)

DavidDrones  

Ever wanted to have a surveillance drone to monitor your surroundings? Of course you have!

Using a Raspberry Pi for the on-board logic, this compact, mobile computer, will create a local port that streams a video in real-time while simultaneously creating Bluetooth sockets to read values sent by a custom android app. The app syncs with the drone and uses user input to send instructions to the drone instantly. This project is fairly difficult to make from scratch, so hopefully the following will make life easier and provide some insight for drone enthusiasts like myself. All the software used for this project is provided. The code used was originally written by myself, but a few lines might have come from other sources. Feel free to modify and share the code to your liking. Please use the information provided responsibly and have fun!

Power in the Apocalypse (How to build a Wood-Gasifier)

tatebullrider 

In this Instructable I will be showing you the steps I used to build my Wood/Biomass Gasifier. It was really a fun project and I would encourage anyone serious about preparedness to build one. Now in case you don't know what a Gasifier is (and don't feel bad if you don't as very few people do lol), they are quite simple, let me explain. Essentially all gasification is, is a form of incomplete combustion, heat from the burning solid fuel creates gases which are unable to burn completely because of the insufficient amounts of oxygen from the available supply of air, it then filters those gasses(which is by weight: 20% hydrogen, 20% carbon monoxide, 50 to 60% nitrogen, and a little bit of methane) And you can really use any kind of Biomass(organic material) that will burn. You can even use things like paper, coal, peat, and lignite. You can then use that filtered gas to run any thing from a generator to a car. So now that you have a basic understanding of what gasification is, lets get down to the build!!!
