CNC Plasma Table
simonrafferty
So , you've bought a plasma cutter and you wish you could accurately cut your designs in metal. Tracing lines by hand gives disappointing results and CNC Plasma tables are way out of your budget. Sound familiar? Well, that's what I thought anyway!
If you have not bought your plasma cutter yet - there are a few things to bear in mind!
  1. The cutter must have 'HF Start' (Cheap cutters sometimes use 'scratch start' where you have to touch the torch on to the metal to strike the arc. Sadly, these will not work with CNC, least not this one!)
  2. If you have the option (can afford it) buy one with 'Pilot Arc'. If the torch moves over a poorly conducting area of metal such as rust, paint or a hole, the arc can go out and it will stop cutting. A Pilot Arc, like the pilot light in your boiler re-lights the arc if it extinguishes. It means you can cut pretty much anything no matter how grotty the surface looks.
  3. If you can, go for a branded cutter. Hypertherm are probably the best - or at least best known. They will give you the best cut quality and cut thickness for a given quoted power (some of the cheaper ones are a bit optimistic with the quoted power and cut thickness!). I started with a cheap cutter (which was actually pretty good) then upgraded to a used Hypertherm 40A machine which was cheaper than a new 'no-brand' machine.
  4. Go for the highest power you can afford. My original 30A cutter claimed to be able to cut 12mm thick - but the most it could realistically cut was 6mm. My new 40A Hypertherm claims 19mm cut thickness - and can indeed cut it (not very tidily though). It will cut nicely at 12mm thickness though.
This plasma table has been designed to work with whatever plasma torch
you have whether hand-held or a full blown CNC Torch. The mounting plate has been designed to be adaptable as possible. You can either attach the torch with zip-ties or U Bolts depending on how often you need to take it off.

Spiral Cut a Wooden Dowel Using a Table Saw
bradk3

My imagination was recently captured by an Instructable by a user named Seamster on how to build a wooden marble coaster. Since it looked like it was within range of my very limited woodworking abilities, I decided to attempt building one of my own. The only real sticking point was the spiral screw used to bring marbles to the top of the coaster.

Seamster used a Dremel to hand-carve the screw from a rounded piece of 2x4. I initially tried this with a store-bought wooden dowel, but quickly lost patience with the process (it turns out that I'm far lazier than I thought). I decided to see if I could figure out a faster way to carve out a wooden screw. I quickly hit upon a very simple method. This has probably been done before, but I'll document it here, just in case.
Step 1: Equipment and material
Picture of Equipment and material
The only woodworking equipment you will need to do this is:
- a table saw with a decent blade
- a miter gauge (pictured)
- a drill
- a suitable drill bit for your screws
- a clamp
- a screwdriver
- a pencil
...and that's it!

Adaptable Wheelchair for handicapped Dogs
aimzzz
A few months ago we discovered Luisa, a handicapped puppy who was born without forelegs on the website of an animal protection organisation (www.pro-tier.de) and decided to build a 3D-printed wheelchair for her. In the meantime we finished the wheelchair and have adopted Luisa. This project is open-source and we want to give everybody the opportunity to help a handicapped animal with this instructable and the 3D-Files we uploaded with it.
The Wheelchair comes in two sizes (The bigger size consists of several parts, so that it can be printed on smaller printers as well) and is adjustable in every possible aspect (width, height,camber,...).
All printed parts were printed by my company (www.multec.de) on our biggest 3d printer (Multirap M420). Of course the files can be printed on any printer, as long as the print area is big enough.

How To Make Pierce Work Jewelry
silvertinkerer

This is how to make jewelry items out of sheet metal with decorative holes. I will show you how to make a pin with the piece I cut out. There is almost no limit to what you can make with enough thought behind this process.
I am using a .80mm thick plate of sterling silver to demonstrate. I will be cutting out a rose design. I will be making this into a pin so I will need the clasp, hinge, & pin parts as well. I am also going to add color epoxy to this later on, you don’t need to do that. I will talk about finishes & other options later. Last but in no way least you need a design to cut out. I went to Google & looked for line art flowers to get my design.

Nail Bottle Opener
sbanas

I've seen these nail bottle openers online, and thought I would make one. They are super simple, but still very interesting, it can basically be a block of wood and a nail. I also wanted mine to be a little bit smaller and look better.

For this project all I used was:

- Scrap 1x4
- Scrap Nail, I used the biggest one I could find laying around
- Neodymium Magnet
- Special Walnut Colored Stain
- Epoxy
- Shellac Finish
- Template
- Black Spray Paint

Eis como funcionam as coisas, em 3D, uma fonte de inspiração para qualquer Engenhocas!


Explain 3D: Understand how things work Alyn Wallace
Explain 3D is a system of interactive educational simulations that can help you to understand how things work. Simulations are built in an interactive 3D environment, which brings fun to learning, is engaging and it also helps to develop logical thinking.
Explain 3D is a great tool for learning new things in a fun way. Principle of operation is shown through interactive simulations. You can zoom in and out, rotate and move assemblies in a 3D environment. Moreover, you can make objects semi­transparent and see operation cycles from the inside. Main parts and objects of simulations are described and explained and you can get more information with a simple tap on the object.
This makes learning more interesting and developes logical thinking, because the user has to think about principle of operation.

Understand 1,700 Mechanical Linkages with these Helpful Animations
Ronald Jaramillo

Mr. Đức thắng Nguyễn (Duc Thang Nguyen) is an engineer from Vietnam. Since his retirement in 2002, he has being working on an amazing animated 3D catalog of mechanical contraptions. Using Autodesk Inventor as a tool, he has documented over 1,700 mechanisms. All from gears, couplings, clutches, differentials to detailed examples of movement conversions. For every mechanism Nguyen has generated a corresponding animated YouTube video. These videos are an invaluable source to understand some of the more convoluted and challenging mechanisms. The video-clips portray a mesmerizing collection of kinetics sculptures on their own and can be enjoyed for their sheer aesthetic value.

Disney 3D Prints with Fabric, Makes Soft Interactive Toys
Caleb Kraft

he folks at Disney have been exploring some really interesting techniques for fabrication. Their latest is this interesting method of 3D printing with fabric.
The process is best described as an automated system for assembling laser cut layers of fabric. Their machine resembles a tiny assembly line more than a standard 3D printer.
First, a vacuum platform holds a roll of fabric with the bottom exposed. A laser cuts the shape of the object and support material from below while the vacuum holds everything in place.
Then, the laser is removed from the area and the “build platform” raises to accept the cut piece.
Next, a tool is deployed to adhere key points of the fabric to the build platform or previous layer.
This process is repeated until you have a solid block of fabric constructed from the desired object and the support material. This block must be manually finished by carefully removing the support material to reveal the “printed” object.

How to grow 100 pounds of potatoes in 4 square feet step by step DIY tutorial instructions 

I always look for ways to improve my gardening efficiency as I don’t have a big yard. I grew potatoes in the last two years. They are really yummy. And it is easy and fun to grow them. The problem is that it takes a lot of space to grow them. Not anymore after I found this approach. You can literally grow 100+ pounds of potatoes in a 2×2 feet space. Excellent idea.
Materials,
  • 2×6″ boards of 8 ft long… 6 pieces
  • 2×2″ board of 12 ft long… 1 piece
  • 2 and 1/2″ wood screws… 96 pieces
Tools
  • Screw drivers
  • Saw (optional, you may get your boards cut at the store where you buy them)

Resolução INCRÍVEL! E Brinquedos à farta, Lagartas 1:10, e aprendam em 11 Sites

Isto é fenomenal, e se sonhavam com o Impossível, bem, ESTE já cá canta!!!
É que para aqueles Protótipos com peças em que a Fidelidade à superfície tem de ser alta, isto é uma forma de não falharem!

Announcing Frosted Extreme Detail (or FXD), our highest resolution 3D printed plastic ever

Today we are excited to announce our newest material, Frosted Extreme Detail! It uses the same resin and printer as our popular material Frosted Ultra Detail (FUD), but it’s almost twice as detailed! Frosted Extreme Detail, or FXD for short, 3D prints using 16 micron layers (vs FUD’s 29 micron layers). This means 3D prints that have unprecedented detail and surface finish, sharper edges, less stepping, and stronger walls and wires. It’s perfect for the most demanding miniatures, figurines, and molds and masters for casting.

Design guidelines are the exact same as FUD, so all your existing FUD designs are printable and you can get started designing amazing new things right away! Pricing for this material is $5.00 startup and $5.99 per CC. The difference in price compared to FUD is that the thinner layers take longer to print and use more material.

RC car tracks in 1/10 scale
isaac_alaska

Earlier this fall, I was in the hobby shop to pick up some parts for my Sawback Gmade GM52000 and saw a set of what looked like tiny MatTracks to install on it. Not wanting to spend the $250 the hobby shop wanted for the used set, i thought to myself, "hey! I can make these!"
Since then, I've been through several dozen revisions, getting the fit and look just right, and trying to find all the necessary hardware, along with setting up my printer to handle the rubber material needed to print the tracks and other rubber parts from.
My original design used my own shape of frame, which improved upon other available designs by offering a longer ground contact patch and slightly higher axle lift, while still maintaining clearances to prevent rubbing. My latest design is actually a direct copy of the tracks used on Ken Block's F150 Raptor, "RaptorTrax". I searched the internet for a clear picture, and using measurements from the photo and specs from the Mattracks website, came up with this design, which looks surprisingly realistic.

Diamond Hotend makes multi-color 3D printing possible from a single nozzle
Francis X Govers III 

Entrepreneurs in Denmark have taken another step towards improving the general usability of 3D printers with the Diamond Hotend, a single 3D extruder unit that can mix and melt three filaments together and produce items in a rainbow of colors.
The most common type of home or hobbyist 3D printer is the Fused Deposition Modeler, or FDM type of printer, which works by melting a plastic filament with a heater element (the "hot end") and extruding the melted plastic out of a small nozzle, much like icing a cake.
Current hot ends can only handle one filament at a time, so the types of 3D printers that can handle multiple colors require a different hot end for each one. This causes a number of problems: the nozzles must be exactly the same height from the work surface, or they will damage each other’s work; the distance between the nozzles must be carefully calibrated and the printer’s software must make corrections to keep the output in the same place.

Make Your Own Plastic
TunerFreak

Many of us use plastic in our projects, but did you know you can melt down and reuse much of the plastic found in your house? In this instructable you'll see how to recycle plastic to be reused for whatever you want.

For this method we will be reusing high density polyethylene (HDPE) plastic. You can identify this plastic by the recycling symbol on the bottom of most plastic containers. HDPE will be identified by a small "2" in the center of the recycling symbol, and will sometimes even be accompanied by "HDPE" written next to the symbol.
When compared to ABS plastic:
HDPE:
  • density - .958g/cc
  • tensile yield strength - 20.6MPa
  • melting point - 129 C
ABS:
  • density - 1.05g/cc
  • tensile yield strength - 41.5MPa
  • melting point - 220 C
While HDPE is not as strong as more widely used polymers such as ABS, it is good for low stress applications such as project enclosures, lightweight mounting solutions, and more. And the best part, it's free!

Motion Detection Alarm System 
nivenenna

A basic USB camera can be used to detect motion in a room. In the following steps we will show you how you can use Reactive Blocks to program a ready to run Java application that sends SMS when motion is detected. With Reative Blocks you make Java SE applications so the alarm application can be deployed on any machine with Java SE and a camera attached or integrated. The application is easily deployed on the Pi since the Raspbian release has Oracle Java pre-installed. .
This is what you need:
  1. Raspberry Pi Model B+ with Raspbian OS
  2. Standard USB camera
  3. Ethernet cable
  4. Screen and keyboard for the Pi
  5. Windows or MAC computer with JDK
  6. Reactive Blocks, an Eclipse plugin, to program the application.
