Brixo, Lego e electrónica! E Tinta que muda de côr(!), Câmara de Infracvermelhos, Massa sem Borax, e a máquina de aproveitar garrafas.

Para facilitar ainda mais a vida aos Engenhocas, aparece agora Brixo, que faz da electrónica um sinples Jogo de Montar!

Com Motores, Sensores, e Bluetooth, e compatível com o Lego, esta nova ideia ajuda-vos a ter ideias, e a pô-las em prática.

What is Brixo? 

BRIXO's electric bricks are normal sized building blocks that are anything but normal. It's like Lego® on steroids, if steroids also gave you superpowers and taught you new languages. 

Basically, they're bricks that safely conduct electricity and connect to your phone to enable you to do all sorts of cool things with your designs.  And no, you don't need to buy a whole new set, because they're used interchangeably with your favourite building blocks to add an element of interactive awesomeness. 

BRIXO bricks include LED lights, motor blocks and even sound, light and proximity sensors. They’re powered by a low voltage Bluetooth controlled built-in battery brick and coated in chrome, a non-toxic metal, to ensure your safety.

A gama de usos possíveis é infinita. 

How to Make Colour Changing Paint

SFXC 

In this tutorial I am going to teach you how to make a colour changing paint. On this occasion, I have chosen to create a paint that changes colour with temperature (thermochromic).

There are so many applications in which thermochromic coatings can be used. Some of these include, colour changing t-shirts, colour changing posters, colour changing birthday cards, promotional items and educational products.

Não faltam Telemóveis, ou Celulares, por casa, com Câmara, mas sem mais uso, nestes dias, então, porque não, transformá-los em Câmaras de Infravermelhos?

É escandalosamente SIMPLES, e é o que vão aprender, neste Instructable: 

Make Basic Infrared Thermal Imaging Camera For Cheap ! Convert Any Camera Into Infrared Thermal Camera

Kedar Nimbalkar

  

How To Convert Any Camera Into Infrared Thermal Camera Very Cheap But Useful Hack . Every Camera Sensor Has Ability To See Infrared i.e. Thermal Part of The Light But The Infrared Blocking Filter Inside Digital Camera's Protects The CCD Sensor From Burning With High Energy Infrared Light Such as Sunlight .

Now , If We Remove The Blocking Infrared Filter The Camera Can Also Able To See Infrared Part of The Spectrum of Light ! Which Is Pretty Cool Because After This Hack You Can See Hot Objects With Your Camera Glowing More As They Emit More Infrared Energy & Many Other Things You Can Do Like See Through Some Clothes , Black Objects Which Takes Teardown To a Next Level !

Mais Diversão, para Engenhocas novos e velhos,  eis como fazer Flubber, em casa, mas sem utilizar Bórax, que não há à disposição em todos os Países:

No Borax Or Starch Flubber/slime/putty

Igioteno 

I've been looking for a no starch or borax flubber for a long time

Some recipes had tide, cornstarch, lotion, clear glue and other ridiculous ingredients

Today, I found a recipe on YouTube on flubber and sounded very believable

I tried it out and a total fail

I then viewed the videos comments and one said just use glue, eye drops and baking soda

I tried it out with using the same ingredients in the video and the same ingredients the comment suggested it turned out great

But it smelled horribly like bleach and it was very wet

It was also very airy and not that stretchy 

So I just used the recipe the comment suggested

How to make a rope out of a plastic bottle?

We often need a strong wire or rope at rest or at the cottage. For example, you need a linen rope, and there's nothing suitable at hands. Don't worry! It is possible to make a long and strong rope out of an empty plastic bottle.
