A Samsung, deu-lhe para se meter no mundo do Arduino, para colaborar com a Internet de coisas, essa história de ter os aparelhos lá de casa todos ligados à Net...



Samsung Announces Their Entry into the Arduino Family
Matt Stultz
 
When you think about Samsung, the first products that come to mind are probably phones or televisions, not Maker-focused electronics. Today, with their announcement at Internet of Things World, Samsung has entered the Maker world with their ARTIK platform, an Arduino compatible family of devices targeted towards Internet of Things applications.
Currently there are three ARTIK devices: The ARTIK 1, ARTIK 5, and ARTIK 10. All are multi-core ARM processors with built in Bluetooth Low Energy. The ARTIK 5 and 10 also include Wi-Fi, BT, Zigbee, and Thread wireless connections.






 




Se sempre quizeram saber como funcionam aqueles Braços de Laboratório e Oficina, com os Ímanes na base, de ligar e desligar, está tudo aqui:


Magnets with an OFF Switch

Can neodymium magnets be turned on and off?
Generally, no. The neodymium magnets we provide are also called, “permanent magnets.”  The word “permanent” means they stay magnetized for a long time.  They are always on.
This is the opposite of an electromagnet, where you have to run an electric current through a wire whenever you want it to act like a magnet.  No flow of electricity, no magnet.
It's also opposite of a "temporary" magnet, like when you stick a (permanent) magnet to a steel paperclip, and that steel acts like a magnet as long as the (permanent) magnet is stuck to it.  Remove the magnet, and the paperclip stops acting so magnet-like.
When people ask us for magnets that can be turned off, we say it’s not possible.  Neodymium magnets, large and small, tend to stay ON.  That's part of what makes them so useful.

How to Choose the Perfect Wall Thickness When Turning Your 3D Model into a 3D Print
Fabian

Since each printing material and 3D model is different, choosing the right wall thickness can be confusing. Yet, keeping these simple tips in mind will ensure that you won’t receive an unpleasant surprise and the walls of your object will have just the thickness they need.
First things first: it’s very important that every surface in your 3D model has been assigned a wall thickness. When using your 3D modeling software it is possible to design a surface without a wall thickness. However, our printers need the information about how thick you intend the wall of your object to be. Thus, when turning a 3D model into a real 3D print, wall thickness is needed.









Eis como fazerem um Braço actuador linear com muito pouco...
Usando Sucata, uma Seringa de cola e uns poucos outros componentes:



Build This Inexpensive Linear Actuator from a Glue Stick
Andrew Terranova

A linear actuator is a mechanism that pulls or pushes a load along a straight line. Pneumatic and hydraulic pistons are examples. So are the threaded rods on 3D printers.
Commercially available linear actuators can be quite expensive, but now you can build your own with just a few dollars worth of parts. Gareth from Let’s Make Robots explains the idea in this post.
The main mechanism is salvaged from a used glue stick. By using a modified hobby servo to drive it, this actuator even comes with positional feedback. It is both surprisingly accurate and surprisingly strong. Check the video to see the finished actuator lifting a 6 lb weight!

Soldar, sem solda? E um Computador a 9 Dólares(!), uma Injectora de Plástico para Fabbers, e Alívio para a Dor, mais uma Câmara de Infravermelhos

Eis como fazerem algo em Electrónica sem as chatices do Fumo e da Solda...
E ainda ficam com uma ligação à prova de àgua!
É bom!



Solder Sleeves
Solder, heat shrink and waterproof your splices in one operation.

This is the easiest way to make soldered splice in your wiring. It is our favorite way to extend the wires on stepper motors.
This part combines a low temperature solder ring inside a piece of clear heat shrink tubing. It also has rings of hot melt glue at each end. You strip each wire, insert one from each end and cross the stripped ends inside the solder ring. You then heat the tubing with a heat gun. The solder and glue melts and the tubing shrinks. You get a reliable, insulated, waterproof and soldered connection in one operation.
It is also great when you need to fan out one wire to several wires. This often happens when you have one ground terminal, but four wires coming to it. Place the four wires in one end and one in the other end.









Um Computador por 9 Dólares? 
Com ligação Wifi, e gestão de Bateria?
Sim, se só precisarem de computadorizar uma Engenhoca, ou terem um Smartphone ou Tablet feito à vossa medida, porque este liga-se a um Televisor, ou Écran de Smartphone, com Monitor é mais caro.



Next Thing Co. Releases “World’s First” $9 Computer
David Scheltema

Snuggly situated in an industrial section of Oakland, CA is Next Thing Co. a team of nine artists and engineers who are pursuing the dream of a lower cost single board computer. Today they’ve unveiled their progress on Kickstarter, offering a $9 development board called Chip.
The board is Open Hardware, runs a flavor of Debian Linux, and boasts a 1Ghz R8 ARM processor, 512MB of RAM, and 4GB of eMMC storage. It is more powerful than a Raspberry Pi B+ and equal to the BeagleBone Black in clock speed, RAM, and storage. Differentiating Chip from Beagle is its built-in WiFi, Bluetooth, and the ease in which it can be made portable, thanks to circuitry that handles battery operation.








Ter a vossa própria Fabriqueta na Garagem, passará certamente, mais cedo ou mais tarde, por terem uma Máquina de Injecção de Plástico, para os vossos Projectos.
Pois aqui vai uma que podem fazer em casa, baseado no Ilustre trabalho da casa Gingery:




Make Your Own Injection Molding Machine
John Hannon

Tried, true, and totally doable. Start cranking out solid thermoplastic parts.

Sometimes there’s a tool you want to buy, but you can’t justify the cost. In that case, why not make it? For me, a plastic injection molding machine fell into that category — and it turns out they’re not hard to make.
I wanted to make solid plastic parts for some of my amateur science experiments. There are a number of ways to make things out of plastic, each with its advantages and disadvantages. Often just cutting raw material to the desired shape works best. Some plastics can be cast by pouring a liquid resin with hardener into a mold (see “DIY Rotocaster,” Make: Volume 41). Vacuum forming works well for making things out of thin sheets of plastic (see “Kitchen Floor Vacuum Former,” Make: Volume 11). I considered making a 3D printer, but for the few plastic parts I envisioned needing, it wasn’t worth the time and money.
Plastic injection molding has been around since thermoplastics were invented. It’s a great way to make many copies of a part quickly, and what I like best is that it’s easy to reuse old plastic objects to make new ones.
So I built an injection molder based on the plans in Vincent R. Gingery’s book Secrets of Building a Plastic Injection Molding Machine. David Gingery could be considered a forerunner of the Maker Movement — he and his son Vincent have written a whole series of books on building tools for the machine shop.

Cheap flying Lego quadcopter
Weseley


Ever needed an excuse to start building Lego again? Now is the time! Turns out Lego bricks can be used to build a perfect symmetrical frame for your quadcopter! And... it's super cheap.
I used Lego Technic because it has holes in the bricks. You can mount the motor's with tie wraps through the holes and it's an ideal weight reduction. For the motor's and flight controller I used parts from the famous Hubsan X4.

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.

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
