Starlite? Muháháháá! E EduExo, uma maravilha, Façam o vosso Micro-Drone(!), imprimir 2x mais rápido, e um Micro-carro!

Um Material que aguenta chamas como se nada fosse, e não passa a temperatura ?
MUÁHÁHÁHÁ!
Entusiasmente...
Algo para as Impressoras 3D, os ferros de soldar, e sabe-se lá quantas mais maquinetas que já vos queimaram os dedos, para não falar de Pegas de Cozinha pá Patroa!
É bom.







A Super-Material You Can Make In Your Kitchen (Starlite?)
NightHawkInLight

In this video I attempt to recreate a lost supermaterial called Starlite. This material could supposedly resist temperatures up to 10,000 degrees Celsius, having undergone testing by NASA and the Atomic Weapons Establishment in the UK. I believe in this video I have come close in function to the original formula for Starlite, but there is still some work to be done. My result works very well, but for a few reasons I may talk about in a future video I do not believe Starlite used PVA glue as it's binder, and I also suspect a different CO2 producer was used instead of baking soda. More experiments are required.

Algo de altamente louvávél, é este Projecto, o EduExo, que vai facilitar bastante a vida a muitos Deficientes Motores, aumentando artificialmente a força de braços debilitados.
Bravo!




EduExo is a DIY exoskeleton kit
Arduino Team

You’ve seen exoskeletons in movies such as Aliens and Iron Man, and perhaps even heard about current experiments with human use. Unfortunately though, if you want to learn about this technology, the barrier to entry is very high.
EduExo, now available on Kickstarter, is an attempt by robotics researcher Volker Bartenbach to bring this technology to the masses. Based on an Arduino Uno, the device takes the form of an upper and lower arm cuff, along with a motor and force sensor to allow it to be used for haptic control.

Quem é que não quer construír isto?
Um Micro-Drone? 
Todo o Geek quer um! Pois Jan Olejnik, dos nossos amigos da Prusa, dizem-vos como o fazer, para vosso deleite e edificação...





How to build a cool & cheap 3D printed micro drone
Jan Olejnik

Radio controlled drones are extremely popular and you can get them in all shapes and sizes. In recent years, one specific type of drone has seen a sudden rise in popularity: micro quadcopters. They fit in your palm but can be powered by high-RPM brushless motors and a two-cell Li-Po battery, so they have, potentially, tons of power. Combine it with first-person video transmission and you have one amazing toy that’s nearly indestructible. And today, we’ll demonstrate that RC vehicles and our 3D printers are a perfect match! We’re going to tell you how to build a cheap, yet powerful, 3D printed mini quadcopter suitable for both indoor and outdoor flying thanks to its diagonal size of 90mm (measured from the motor to motor).

Dos antípodas, que é o mesmo que dizer, do outro lado do Mundo, vem-nos ainda mais esta Dica do sempre bem-disposto nosso amigo da Maker's Muse, para acelerarem nas vossas Impressões 3D, com umas pequenas mudanças aqui e ali...







3D Print parts TWICE as fast with simple slicer tweaks. 3DP101
Maker's Muse

In this video I'll show you how I created a super fast slicer setting "0.3mm Stupid Fast" to create strong prototype parts quickly and reliably on my Prusa MK3 3D Printer. This might be obvious to some, but many 3D Printing enthusiasts never try and push the limit with their print settings. You'll be amazed just how quickly you can churn out parts with a few simple tweaks - in some cases more than twice as fast and just as strong! Just want to see my settings??? Jump to 6:27 ! :)

...E como  não quero que vos falte nada, terminamos com este engraçadíssimo Micro-Carro, tele-controlado, e MESMO pequeno!
Até dá para brincar com o Gato, ou assustar as míudas!
LOL







Micro RC Car
KRP-01

Remote controls cars are now widely available, however there's one astounding model that one can scratch-build. It measures merely 2inches long but is equipped with proportional control system including 12step steering control, headlights and more!

Raspberry Pi 3, A+! E alojar as Impressoras, Mini-satélites(!), Lixar sem Stress, e o PVC sem Mestre

A placa Raspi não pára!
Agora um autêntico Computador, Quad-Coore de 64 bits, e o que mais,  a 1,4 GHz, vão ver à página deste Link as Especificações desta bela máquina!










Raspberry Pi 3 Model A+ Unboxing
e14phil

Introducing the Raspberry Pi 3 Model A+, the latest product in the Raspberry Pi 3 range.
Like the Raspberry Pi 3 Model B+, it boasts a 64-bit quad core processor running at 1.4 GHz, dual-band 2.4 GHz and 5 GHz wireless LAN, and Bluetooth 4.2/BLE.
The dual-band wireless LAN comes with modular compliance certification, allowing the board to be designed into end products with significantly reduced wireless LAN compliance testing, improving both cost and time to market.














...Algumas dicas que não são óbvias, e são mesmo essas as que nos tramam, quando não as sabemos...
Saibam então como fazer uma caixa para as vossas Impressoras 3D, que permita uma temperatura estável, sem abafar a máquina, e mais!
Dicas porreiras.






5 Tips for Building a 3D Printer Enclosure
3D Printing Nerd

While at Printed Solid, I spoke to David Randolph about 3d printer enclosures. They sell a number of enclosures, and even white label their enclosures for other resellers. Knowing I tried to build one myself with Bill Doran, I asked Dave to give me his five best tips for building one!













MINI-SATÉLITES!!!
Muháháhá!
Malta Estudante, e Super-Geeks, aprendam como construír estes bichinos, mas para durarem, que lançá-los, não é pela UPS, ou pelos Correios.
Ainda... LOL
Maravilha.

Build a CubeSat Satellite that actually works, Part 1: Make it Resilient
Bill Marshall

It’s such a great idea: students in schools and colleges inspired to become the next generation of Space engineers by building and orbiting their own satellite. But it’s not a new idea. The first amateur satellite, OSCAR 1 was actually launched in 1961 as a secondary payload - only four years after Sputnik 1. Project OSCAR continued with more launches until 1969 when the Radio Amateur Satellite Corporation (AMSAT) was formed to co-ordinate further activity. The OSCARs are primarily amateur radio communication satellites built by students in educational establishments worldwide. Three were constructed at Surrey University in the UK starting with UoSAT-1 (OSCAR 9) in 1981 then UoSAT-2 (OSCAR 11) in 1984 and UoSAT-3 (OSCAR 14) in 1990. The educational purpose behind these satellites was highlighted when a special purpose radio receiver with software for the BBC Microcomputer became available. In the late 1990’s the CubeSat was born when it was realised that thanks to microelectronics it had become possible to squeeze most of the functionality of an OSCAR satellite into a 10cm cube. Since the first one made it into Low-Earth Orbit (LEO) in 2003, many more have followed. But the failure rate has been high for two reasons: the stresses of launch can ‘break’ the CubeSat before it even reaches orbit, and the Space environment is very hazardous for delicate electronics once orbit is achieved. What can be done to increase the likelihood of success?

Garage Dust/Sanding Enclosure
corbor4shore

INTRODUCTION:
I have a very small shop in my two car garage. Unfortunately I have to share that space with two cars. When I am sanding, routing or drilling, dust seems to coat every surface in my garage, including my wife car. I was tired of washing my wife’s car so I needed to find a solution to all the dust I was creating. I did some research and found some sanding downdraft tables, but I couldn’t imagine those working without an incredibly powerful vacuum (which I do not have), plus they do not contain the dust jettisoned out. I then started looking at bead blasting cabinets and found that I liked the containment aspect of the cabinet but I needed the downdraft capabilities of the sanding tables, so I decided to create a hybrid.

Aprendam 5 lições duma assentada, sobre como usar o humilde, mas tão útil, Tubo de PVC para uma data de coisas boas, cortesia da nodda amiga, audreyobscura, que não pára de nos surpreender com a sua creatividade:




PVC CLASS
audreyobscura

Plastic PVC is most commonly used by plumbers and very clever DIY enthusiasts. This material and pipe were designed to transport water, as it cannot wear out over time like rusting metal can. PVC is also structurally very strong. When parts are constructed properly, it can support structures that are hundreds of pounds!
This class aims to go over the material properties of PVC as well as the most common ways it is worked, machined, joined, and finished. You'll be inspired to create furniture, agriculture projects, and more after learning these simple techniques to work with PVC.
