Make Your Own LED Stroboscope

GreatScottLab

In this project I will show you how the stroboscopic effect works and how we can use it to determine the RPM of a motor. Also I will be showing you how to create a simple LED stroboscope at home by utilizing an Arduino or a 555 Timer circuit. Let's get started!

CNC Furniture: From Sketch To Prototype Using Rhino & Grasshopper!
Ezequiel Lopez

About Carlos and Modifile
Carlos Travaini is the lead designer at Modifile.com. He's an Argentinian that moved to Venice, Italy many years ago and is constantly busy alternating between private projects he gets hired for and his new website.
Intrigued by how he's able to mix all the elements that enable him to create all his fun and very original furniture pieces, I asked him for a favor: I wanted to get to know his creative process. Note that most of the times this is a very private process and many artists simply won't let you into that space, but Carlos was gracious enough to let our cameras in not only during the sketching portion but the entire process, from sketch to prototype production.

Homemade Mini Bend Brake
Improbable Construct

In this Instructable I will show you how I made a Mini Bend Brake to bend some 1/16" aluminum.
I needed to make clean straight bends in strips of aluminum for my Hidden Bookshelf Light Switch.
I had pretty good luck bending the aluminum in my bench vise, but it was hard to keep the bends square and even.
So, this is what I came up with.

The ultimate guide to designing 3D printed interlocking parts
Katarzyna Plewa

With 3D printing technologies, the design freedom is just endless. Additive Manufacturing allows for the absolutely new use of design tools, such as interlocking tools. Thanks to 3D printing you are not able to combine different technologies and materials. Discover the benefits of 3D printed interlocking parts now!

In this blog post, we will go over the advantages of 3D printing interlocking parts, we will advise you which 3D technology will the best for different production needs and our 3D printing experts will show you our own study case of designing interlocking parts.

What are the benefits of 3D printing interlocking parts?

First of all, Additive Manufacturing gives you a wide range of materials, providing you with the best choice for your production needs. Every product you design is different, and to give you the best 3D printing experience we offer 18 materials across 8 3D technologies. Surely, one of them will perfectly fit your manufacturing preferences, whether you need your parts to be flexible or heat resistant.

Additive Manufacturing gives you amazing design freedom as the technology is capable of much more than traditional manufacturing methods. Your products can reach a new level of complexity allowing for better solutions for your production needs. Indeed, with 3D printing, you can easily design interlocking parts thanks to the high accuracy of 3D printing.

A não ser que queiram queimar Motores, e aleijar os dedos, podem muito bem recootrer a este Mini-Curso de 5 Aulas, sobre como montar e controlar as bestas que arranjam nas Sucatteiras e afins, para fazerem aquele Kart eléctrico, ou lá o que seja...

LARGE MOTORS CLASS

randofo

In this class I will show you how to control motors that are suitable for building go-karts, electric scooters, large robots, and much more. This requires a very different set of knowledge and skills than would be necessary for controlling a small hobby motor.
This class is intended for students with some experience working with motors, and mechanical systems. By the end of the class you will learn how to pick the correct power supply, build a control circuit, and adjust the speed of a motor. You will also learn how to make a circuit which reverses the direction the motor is spinning.
Motor control is demonstrated by a range of techniques such as using motor controllers with analog throttles and also with Arduinos and motor controllers.
I hope that you will come join me in the wild world or large motor control.

Um Oscisloscópio de Bolso? 

Ainda melhor, do tamanho duma caixinha de Fósforos!

Espantem os Colegas com esta pequena maravilha, que nem preciso de dizer mais nada, bolas, isto é a ambição de qualquer Engenhocas que se preze!

Oscilloscope in a Matchbox - Arduino

Peter Balch

Why would I want a tiny oscillscope? I've got a room full of electronic Stuff including four oscillscopes. But it's a fuss using them. It would be nice to have something that fits in my pocket, that sits next to the circuit I'm working on and that's as easy to use as a multimeter.
This oscilloscope costs the price of an Arduino Nano (£2 and a display (£3) plus a few pence for resistors, etc. It's specification is:

•  max 1M samples/second, min 1000sps
•  8-bits per sample
•  DC 0-5V; AC +/- 550mV, AC +/- 117mV, AC +/- 25mV
•  USB "PC scope" or built-in display
•  could be battery-powered
•  optional logic display
•  optional frequency meter
•  optional voltmeter

Intro: EWaste 60$ 3DPrinter

mikelllc

This project describes the design of a very low budget 3D Printer that is mainly built out of recycled electronic components. The result is a small format printer for less than 100$.
First of all, we learn how a generic CNC system works (by assembling and calibrating bearings, guides and threads) and then teach the machine to respond to g-code instructions. After that, we add a small plastic extruder and give an overview on plastic extrusion calibration, driver power tuning and other few operations that will bring the printer to live. Following this instructions you will get a small footprint 3D Printer that is built with about an 80% of recycled components, which gives it a great potential and helps to reduce the cost significantly.
On one side you get an introduction to machine building and digital fabrication and on the other side you get a small 3D Printer built out of reused electronic parts. This should help us to be more conscious about the big problems related with e-waste generation.

4-Axis CNC Hot-wire Foam Cutter (Arduino+Ramps1.4)

rahulsrajan

A CNC Hot-wire cutter is an awesome tool to have when you are building aeroplanes out of foam. It allows the ability to cut out any aerofoil shape from a CAD design accurately. A properly configured machine can save you a lot of effort and produce a smooth finish.
The machine has a Nichrome wire stretched between two towers. The wire is heated by passing current through it and the towers move relative to each other to define the shape of the cut. The 2D CAD design to be cut out is turned into G-code and fed to the machine, which moves in four independent axes to create complex contours like tapered wings.
The motion of each axis can be achieved by any means such as linear bearings on smooth rods or by using drawer slides of various sizes. Each axis is driven by a stepper motor through a Leadscrew, a GT2 belt and pulley can also be used depending on the size of the machine. The cutting forces involved is minimal and the construction only needs to be rigid enough to withstand the tension of the wire stretched between the towers.

Nem de propósito, aprendam aqui como fazer Moldes, nem que seja para técnicas menos radicais que a Fundição! LOL

MOLD MAKING & CASTING CLASS

Paige Russell

Welcome to the infinite world of Mold Making & Casting!
In this class, you'll learn how to make easy molds that will allow you to cast multiples of virtually any object – including 3D prints – in a variety of materials, like soap, plaster, chocolate, crayon, resin, metal, and more!
In this introductory class, you’ll gain a solid understanding of fundamental techniques that will empower you to tackle almost any mold making project.
You'll learn what undercuts are and how to recognize them on your models, determine what kind of mold and mold material to use, how to build and properly seal mold walls, and how to cast in numerous materials.
It may seem daunting, but I’m a product designer and ceramicist who has been making molds for over 15 years, and I'll be with you every step of the way. I look forward to teaching you how to cast your way to a customized world!

Laser Engraving on Your Prusa MK3

marzsolt 

Yes, your 3D printer is totally capable of making awesome laser engravings. Follow along to see how I did it. Hint: it's not complicated (well, probably just a manageable amount), and I created tools to make it easy for beginners and advanced skill levels to jump in and laser away.
There are many steps and I included a lot of details. I want to be sure you understand why and how things are happening.
Disclaimer: Lasers are very dangerous, so you need to use proper care and basic common sense to not get in trouble. I warned you, I will not be responsible if you shoot down a space pirate... or lose an eye. Arrr.
