Écran táctil Arduino, Uma Patente da Google, e um Motor V8 em Miniatura

Isto  é importante, agora têem à vossa disposição um Écran táctil Arduino, o que vai dar mais vida aos vossos projectos, qualquer engenhoca electrónica torna-se muito mais interactiva e configurável.
E isto, a funcionar com de 6 a 9 Volts e menos de 200mAh!

ArduinoLCD lets tinkerers add a touchscreen to their projects

Dave LeClair

For all the Arduino microcomputer addicts who love tinkering around on really cool projects, here's something that will might help you bring those projects to the next level. It's the ArduinoLCD from EarthMake, and it offers an affordable way of integrating a touchscreen into your latest gizmo.
The ArduinoLCD is a 3.5-inch touchscreen with 320 x 240 resolution. Obviously, this is not going to blow anyone away with stunning HD visuals, but it will work fine for most projects. It has a 500:1 contrast ratio, which should create good blacks on the screen. The screen is also LED backlit, so it will be plenty bright, and is capable of displaying 65,000 colors.
The touchscreen features its own 16-bit GPU. It also has 4MB of internal flash memory designed for storing macros, fonts, and bitmaps. Conveniently, it comes with a mounting bracket, which should make it easy to integrate into your projects.

Eis algo que parece vir dum Filme do 007, mas é real, e obra da Google! Uma obra-prima de inter-actividade, eis um Relógio com um Écran transparente onde aparecem mensagens, por isso, apontam o gajo para um Artigo, e lêem mais informações, ou vêem a direccção certa para onde querem ir, quando andam por aí.



Google patents smart watch with flip-up, transparent display

Dave LeClair

It was not long ago that the internet was going crazy over Google's Project Glass, and now Google has our attention again with the patent of a "smart watch." This watch appears to use technology similar to the glasses, but with a flip-up touchscreen instead of lenses.
From the looks of things, this watch would present notifications and other information transmitted from your smartphone right to your wrist. Let's be honest, a quick look at Kickstarter would let you find tons of watches that do this very thing. Google's potential watch stands out, however, because of the transparent screen that could "see" objects around you.
So what does this mean for real-world applications? The watch could offer GPS functions based on a landmark it detects around you. The watch could also detect small objects around you, so if you focused it on a product in a store, it could give you more information, which could prove quite useful.

Uma Obra de Arte, para os Amantes do desporto Motorizado, este Motor V8 em Miniatura, que funciona mesmo!
Há quem faça disto em Portugal, mas não têem vontade de fazer dinheiro, penso eu...

World's smallest supercharged four-stroke V8 engine now in production

Brian Dodson
 Giant-scale model cars (and airplanes) powered by small gasoline engines have been popular with adult racers for quite a few years now. The largest scale models available through conventional RC hobby outlets are one-fifth or one-sixth scale, but the serious racers go quarter-scale. Now the smallest (quarter-scale) blown V8 gasoline engine in commercial production is being turned out by Conley Precision Engines to power.
A quarter-scale gasoline-powered car is about 1.2 m (4 feet) in length, weighs around 50 kg (110 lbs), and can top out at over 160 kph (100 mph). The engines for such large models are usually two-cycle engines not dissimilar from the engines that power weedwackers and leaf blowers, typically beginning at about 33 cc (2.0 cu. in.) displacement, providing 3 to 4 hp at 6-8000 rpm.

Why then is the racing community reacting with crackling excitement over the Conley Stinger 609, a new quarter-scale V8 with supercharging, 100 cc (6.09 cu. in.) displacement, and a power output of 9.5 horsepower at 10,000 rpm – especially with a list price over US$7000? Simply enough, other engines don't look or sound right.

O Inverno vem aí porque não adaptar skis às vossas cadeiras de Rodas, quando forem à Serra da Estrela?
Ou para outras deslocações, aí pelo Norte...

Wheelblades mini wheelchair skis for snow and ice

When the going gets snowy and slick, people turn to snowshoes and ice cleats to get them over wintery ground. Those in wheelchairs don't have quite as many simple options. Essentially mini skis that lock onto the front wheels of a wheelchair, Wheelblades are designed as an easy-to-use solution that aid traction and give a little extra oomph through snow, ice and slush.
Like a snowshoe does for the person wearing it, the Wheelblades spread the weight over a greater surface area. Instead of slipping and sinking, the front wheels float and glide. A pair of channels on the base of the ski compress the snow, which increases stability.

Remata-se com esta Coroa feita em Titânio, pois, quando se tem à mão uma Cortadora de Jacto de àgua, é fácil fazer maravilhas, mas algo como a TechShop ainda cá não mora...

The Queen's Round Metal Hat


Every queen needs a round, metal hat, or "crown".  This one is technically a 'coronet' as it does not close in the middle.  The queen is Titania, queen of the faeries, daughter of Titans, and fittingly, her crown is made of titanium.  The parts were designed using Autodesk Inventor and fabricated with a CNC waterjet cutter, in the traditional craftwork of olde.  At TechShop.
