Será que dois Ímanes de força igual, exercem o dobro da força? E dois Ímanes empilhados?

Para responder a essas questões, vejam este interessante artigo da K&J Magnetics, que também tem um Link para uma calculadora de Repulsão magética:

Doubled Forces 

If you have 2 magnets repelling one another, is the force doubled? If you stack 2 magnets together, is the pull force doubled? These are good questions that we receive from time to time. The answers are found in the mechanical engineering study of statics, the study of forces on non-moving objects. We’ll try to answer these in plain English, avoiding as much engineering jargon as we can!

Batthead batteries could allow any device to be wirelessly controlled

Ben Coxworth

There are already a wide variety of devices that can be turned on and off by your smartphone, although they typically need to be Wi-Fi- or Bluetooth-enabled. The makers of Batthead, however, have taken another approach. They're creating Bluetooth-controlled batteries, that will allow any ol' device using them to be powered up or down via your phone.
The Battheads themselves are AA-sized rechargeable NiMH batteries, each one containing a Bluetooth Smart Chip that allows it to communicate with your phone.
There's also an integrated accelerometer, making it possible for the batteries to detect when they've been moved. This could allow for things such as flashlights that come on whenever they're picked up, or devices that automatically turn off when they haven't been used in several minutes.

Enxerte-se um Tomateiro, encima duma Batateira, e cultivam-se Batatas, e Tomates, no mesmo espaço!

Uma ideia simples... Mas ninguém a tinha tido!

TomTato plant grows both tomatoes and potatoes

Ben Coxworth

 

We've seen a number of innovations that allow for gardening in small spaces, including a ferris wheel-like contraption, a mat that shows you where to plant specially-prepared seeds, and a system that lets you grow vertically-stacked veggies in your window. The TomTato, however, is in a league of its own – it's a single plant that produces both tomatoes and potatoes at the same time.

Created by UK horticulture company Thompson and Morgan, the TomTato is not the result of genetic engineering. It's "simply" the top of a cherry tomato plant and the bottom of a white potato plant, that have been grafted together at the stem.

Todo o Engenhocas acaba for fazer uma Chiqueirada, mais cedo ou mais tarde, e, meus amigos, é desta conversão de Aspirador que nós precisamos!

Pois, se serve para aspirar, e separar, a poeira de lixar Placa de Gesso!

Drywall Sanding Dust Collector/Separator

Randyrandy74

Drwall sanding produces lots of dust no matter how dust free your joint compound claims to be, Drywall dust will quickly clog your shop vac filter and shorten the life of your vacuum.

There is a wide selection of drywall dust separators on the market from $50 or so on up to several hundred dollars for a nice Festool extractor. Being a DIY homeowner, taping drywall is not a full time job and doesn't warrant spending the money, so I decided to make my own with about $20 at the local hardware store, This price can be more or less depending on how you make it and what items you might have lying around, I could have used an old bucket but opted to buy a new one for this project, about $5 for bucket and lid at Lowes.

Converting Cordless To Lithium Li-Po

henal

As time moves we find that our drill don't cut it any more as now there are all of these new powerful cordless drills with lithium but the price of one of them cost about an arm or leg so what do you do?
Convert them to lithium,

Motor technology has been the same since 20 years ago and it's still the same in all new drills "DC Brushed Motors"

Up on opening my "Old" drill and having a look at my motor my motor looked very new and the brushes ware far from worn if not still would go strong for many years to come.
On the other end the battery's ware totally on the end of its life.

Uma Bússola no Smartphone? E uma Super-Funda, um separador de moedas em Lego, Construíndo Repraps, e um Gato

K&JMagnetics surpreende-nos com este Artigo, onde nos ensina que há Apps para aproveitar os sensores magnéticos desses Smartphones, para detectar o Norte, a força dum campo Magnético, e mais....

iPhone Magnetic Measurements

Modern smartphones have internal magnetic sensors that can detect magnetic fields.  Learn more about how the output of these sensors can be useful in finding north, identifying the direction of the earths’ magnetic field, identifying poles of magnets and checking compliance with air shipment regulations.

Detect Earth’s Magnetic Field In our earlier article, The Earth is a Magnet, we described the earth’s magnetic field.  As most of us know, we can measure the direction of this field with a compass to figure out which way is north.  Most smartphones come preloaded with a compass application that does exactly that.

While most folks aren’t using this compass to figure out which way to go, they are using magnetic information indirectly.  When using an iPhone for directions, the phone considers not only the GPS sensor data, but also the magnetometer and accelerometers.  That’s part of how it can tell which direction you are pointed in.

The magnetic field sensed by the internal compass is not actually pointing to the north pole.  In fact, unless you live near the equator, it is probably pointing mostly down into the ground!

Slingatron to hurl payloads into orbit

David Szondy

People have been shooting things into space since the 1940s, but in every case this has involved using rockets. This works, but it’s incredibly expensive with the cheapest launch costs hovering around US$2,000 per pound. This is in part because almost every bit of the rocket is either destroyed or rendered unusable once it has put the payload into orbit. Reusable launch vehicles like the SpaceX Grasshopper offer one way to bring costs down, but another approach is to dump the rockets altogether and hurl payloads into orbit. That's what HyperV Technologies Corp. of Chantilly, Virginia is hoping to achieve with a “mechanical hypervelocity mass accelerator” called the slingatron.

LEGO Coin Sorter

sherrycayheyhey

The Design

I wasn't too thrilled about how the case came out but I was happy with the mechanism part. Many of the LEGO coin sorters I've seen require the whole unit to be tilted which I think looks weird so I wanted to make my coin sorter with a sloped ramp with the rest level.

I wanted to enclose the mechanism to create a bit of mystery and get people thinking about how the machine might work. I also liked the idea of being able to see the coins drop so I added a couple of extra layers to make the machine taller.

This machine is made to work with US coins but could probably be very easily modified to work with other coins.

Adventures in RepRap Construction

Andrew Back

A report on the first experiences of building a RepRap 3D printer.

Over a weekend back in March my local hackerspace group, Bridge Rectifier, hosted a 3D printing workshop at which we learnt how to construct a RepRap printer and to use a software toolchain for creating, processing and printing 3D models.

For the workshop we were very fortunate to be under the expert tuition of Alan Wood and Mike Beardmore from Thames Valley RepRap User Group (TVRRUG), a 3D printing enthusiast group that has constructed over 100 RepRap printers and designed its own enhancements.

Around 30 people took part in the workshop and following the introductory presentations we split into two groups: one working on printer construction and a second learning the software tools.

The machine we built was a variant of the RepRap Prusa Mendel, provided to us in the kit form as used in TVRRUG's own printer self-build rounds.
