Como dispara:

Magnetic NERF pistol
EdgarInventor

As strong as the 10mm Neodymium magnets you can get! It re-sets back at the flick of the lever, as the piston magnet is turned around, and so gets repelled by the 2 side magnets. Files at: https://cults3d.com/en/3d-model/gadget/magnet-nerf-pistol

Como se re-arma:

Repeat fire Neo NERF Shoot, turn, reset!

Rocket Boat

makjosher 

Every year in October, some friends of my parents have gotten together at a cabin next to a small pond. As a kid it was one of my favorite times of the year, as it meant I got to hang out with my two favorite cousins and one other friend. One year we got the idea to build a simple wooded boat and attach some model rocket engines to it. We built the boat and launched it from the dock. That boat only went about 6 feet, but an annual tradition was born. Over the next few years we built several more boats - most were dismal failures. Eventually, my brother decided to have a go at building a boat and his boats were considerably more successful. We gradually increased the rocket thrust and even added a second rocket stage. Our most successful run made it around half way down the pond before the boat lifted off the water and tumbled out of control. This year I decided to build my first boat in quite some time - this is the story of that boat.

Para brincar com o Tareco, nada melhor que esta máquina Laser, que vocês controlam com o Smartphone, e é tão fascinante para o Gato, como para o Dono...

Smartphone Controlled Cat Laser

Ikkalebob 

I've been wanting to start exploring the world of microcontrollers and programming for some time now, so I came up with this simple project which uses an app called "Blynk" to allow you to wirelessly control an Arduino board through your wifi. Now obviously the end result isn't the most practical device you'll ever build, but this was a great way for me to learn the fundamentals of programming Arduino and it can help you to learn too.

I've tried to arrange this project in an easy-to-follow format so it's ideal for someone who knows nothing about Arduino, but there's a lot of room for tweaking and improvement in my code that would allow more advanced users to get some use out of this project too.

This is a project that's been done before a few times, but I wanted to add something new by giving the system remote control functionality.

Com tanto Ìman de Neodímio à mão, eis uma boa ideia para usar um, neste caso, para serrar a direito, com um simples Serrote Manual de lâmina larga:

DIY Magnetic Hand-Saw Guide - Extremely Accurate Cuts!

Yonatan24 

I think handsaws are WAY better than circular saws for many reasons, but I always come across one problem: I'm never able to saw perpendicular, aka square, at a 90° angle. You can see the example for this here.

I have (finally!) received the saw that I won back in the 2015 Shelving Contest with my Ultimate Magnetic Pegboard. It's extremely sharp, beautifully made, and has a really comfortable handle. However, it is very thin, and doesn't have any aligning support on the top, so it bends really easily while sawing.

A well known solution for this is a Miter-Box. I've bought one, but it just doesn't work. Instead of having the sides hold the saw, I just saw into the plastic...

One day I was daydreaming a bit: "If I take that magnetic dovetail jig that I saw in one of Jay Bates' videos, and align it differently, will I be able to use it for sawing at 90°, perpendicular, and square to the wooden board that I'm sawing?" So I do a quick search and: "Wait, WHAT? It costs 50 DOLLARS?"

"OK, nevermind. I'm making my own!" I decided that I'd make myself a magnetic guide, which ensures that the cut will be square in all directions. Alternatively, you can modify it, and use it for dovetails, miters, or anything else.

Make a Router Planing Jig

WOmadeOD  

No Planer/Thicknesser, or maybe it's not wide enough? If you have a router, then this router planing jig might be right up your street.

I built mine as an improvement over what I've used in the past to plane wide planks for waterfall tables. I estimate it halves the time to get the same job done as before - not bad for something cheap, easy, and quick to build!

Let me show you how I built and use it.

Use the Instructable and video to make your own - there is even a SketchUp model for free download!

CNC Drum Plotter

lingib 

This instructable describes an A4/A3 plotter made from a section of plastic pipe, two BYJ-48 stepper motors and an SG-90 servo. Essentially it is a flat-bed plotter rolled up into a drum.

One motor rotates the drum while the other moves the print-head. The servo is used to raise and lower the pen.

This plotter has a number of advantages over a traditional flatbed plotter:

significantly smaller footprint

only requires one linear guide rail

simple to construct

cheap

An on-board interpreter accepts the gcode output from Inkscape.

Communication with the plotter is via a bluetooth link.

The plotter is compatible with the CNC Graphics Tablet described in my instructable http://www.instructables.com/id/CNC-Graphics-Tablet/.

While not a precision instrument the accuracy of this plotter is satisfactory for its intended purpose of transferring watercolor outlines on to paper.

Attiny programado com Arduino, Circuitos, Bancada, Oficina, e Sucata

O Attiny é um Chip programável, que vos ajuda em muito  Projecto onde o tamanho é um factor essencial, mas programá-lo pode ser uma embrulhada...

Já não  é assim, com este simpático Instructable dos nossos amigos Webgeeks, que vos vai dar asas, porque o passam a programar com um Plug-in para o Arduíno:

Arduino Attiny Programming Shield

webgeeks 

An Attiny is a great alternative to the atmega328, it is for those projects that need few GPIO pins and need to be portable. But unlike the atmgea328 the attiny cannot plug into an Arduino board and be programmed. Another way would be to use a breadboard and an Arduino uno as ISP, but it would be really messy and it would be hard to program it this way multiple times.

A better way would be to program it on a shield and in today's instructable I'm going to show you how to build an attiny programming shield. The shield is easy to build and plugs on to an Arduino to program. So all you have to is plug the attiny on the IC Holder and you can program it.

Ultimate Workbench

mikeasaurus

The ultimate workbench is your go-to place when you need to get a job done. It's got a solid wood work surface, great lighting, a vice to hold down your work, and of course all the important tools at the ready in drawers underneath. Also, it's on casters. Which is really the best part about this workbench, the mobility it provides.

Setting Up a Workshop

woodskills

This Instructable on Setting Up a Workshop is brought to you by WoodSkills. For woodworking plans, woodworking courses, books and tutorials, please visit WoodSkills

The first step in setting up a workshop is to establish your needs. A suitable location for the workshop must be determined. Workshops can be located in any part of the home or garage, but ideally the basement or garage are very suitable locations. You should plan for future expansion prior to designing a workshop, since at some point in the future you will outgrow your present shop. Many factors are taken into consideration in designing a workshop. Storage, lighting, ventilation, power requirements, and noise reduction are important considerations.

The typical woodworking shop requires a lumber storage area, a workbench, tool storage, stationary machine area, and a finishing area. Ample space should be provided to move between the bench and walls, and to provide the necessary clearance to be able to use long, wide boards and panels.

Rare Earth Magnets From Old Hard Drives

Lorddrake

It happens to all of us eventually.

You've upgraded your laptop from that ancient cinder block to a sleek new light weight model.

You got a new desktop PC to replace the one that was so old the keyboard was in Sanskrit.

You have moved over all you family pictures, every song you've collected since high school, all those movies you download ... completely legitimately .. *cough cough* .. no really ... OK ... moving on

So what do you do with the Hard drives you removed before sending the rest of your old computers to be recycled?

I'll tell you what to do .. You grab your tools and gut them for the glorious rare earth magnets (As well as a few other goodies) that are hidden inside.

Complete Motor guide for Robotics

taifur 

Robot is an electromechanical device which is capable of reacting in some way to its environment, and take autonomous decisions or actions in order to achieve a specific task.

Roboticists develop man-made mechanical devices that can move by themselves, whose motion must be modelled, planned, sensed, actuated and controlled, and whose motion behavior can be influenced by “programming”.

This definition implies that a device can only be called a “robot” if it contains a movable mechanism, influenced by sensing, planning, actuation and control components. Motors and actuators are the devices which make the robot movable. Motors and actuators convert electrical energy into physical motion. The vast majority of actuators produce either rotational or linear motion.

In this instructables I will explain more common types of motors and actuators, their basics and how to control them.

Mais um Projecto divertido da KJMagnetics, como separar Metais, com Ímanes, não só separar Metais Ferrosos, de Não-Ferrosos, e até Alumínio, de outros Materiais!

More About Magnetic Separation

Last month, we wrote about how magnets are assembled for magnetic separation applications – attracting iron, steel, or other ferromagnetic bits to get contaminants out of other materials. It was a fun example of some specific ways that magnets are selected and assembled for this task.
Still, some of you might be thinking, “Big deal, iron sticks to magnets. We knew that.” We have to agree that’s true.

What if there was a way to use magnets to separate metals that are NOT attracted to magnets? If we could separate aluminum cans (which magnets don’t stick to) from other, non-metallic trash, would that be amazing?
Read on to learn more about how this is really done!

Silicone Box Mold For Prop Making

Joe Sargent
Silicone box molds are a fairly simple and very effective way to mold simply shaped objects. I molded a pipe wrench, but you can mold many things (but not everything, which I will get to later) with this style mold. Very soon I will be posting the second half of this process, which is casting a part from the mold. I will be making a flexible foam wrench that looks exactly like the real thing, but that you can hit someone over the head with. Just creating a mold takes many steps, each of which is incredibly important, so just focusing on that should help maintain clarity. This style mold is best used with a simple, fairly uniform shape, with very little or no undercuts.

Power HD Ultra-High-Torque, High-Voltage Digital Giant Servo HD-1235MG

Overview

The HD-1235MG is a giant-scale (also called 1/4-scale) digital servo from Power HD can deliver nearly twice the torque of our strongest standard-size servo, offering up to 560 oz-in at 7.4V or 490 oz-in at 6 V (if you need even more torque than this, check out the much larger Torxis monster servos). The picture on the right shows how the giant-size 1235MG compares to our popular 1501MG standard-size servo.

The entire gear train is metal, and the output shaft is supported by two ball bearings for improved performance. Unlike typical hobby servos, the 1235MG has an operating voltage range of 6 V to 7.4 V. This servo works with standard RC servo pulses at frequencies up to 333 Hz. The 12″ (300 mm) lead is terminated with a standard “JR”-style connector, which is Futaba-compatible.

Case with 40 super magnets

In order to entice Mr. Macho Man to read the warning label, we printed it on glossy paper and added many visuals - just like he is used to from his favorite "magazines."
The brochure is translated into 6 languages and uses direct and straight-up wording - from one man to another. It's easy to comprehend, even for someone who normally ignores warning labels as a matter of principle.
