Desktop Water-jet, sim, cortar TUDO em casa! e Velleman, um Site a ver, imprimir 3D em Teflon(!), um Kit de Sobrevivência, e um Robot expansível!

Em cada Garagem, uma Fábrica? 

Agora sim.

Com uma Máquina CNC de corte por Jacto de Àgua, corta-se prácticamente, tudo, e a partir daí, é só cortar e montar...

Mas custam 100.000 Dólares!

Não esta pequena maravilha, uma Máquina como essas, mas topo-de-mesa, e a custar 6.000 Dólares. E que funciona a corrente normal, de habitação, pronta a ligar e a trabalhar.

De tal maneira, que o Kickstater rendeu 10 vezes mais que o pedido, e agora, é só comprar.

WAZER - The First Desktop Waterjet

Tom Spendlove 

Nisan Lerea and Matthew Nowicki met at Penn Engineering working on the Formula SAE design competition vehicle, and did undergraduate research in manufacturing. One research topic was low-cost waterjet prototyping, and Lerea and Nowicki quit their jobs in 2015 to develop and refine their waterjet cutter. Along with their team of manufacturing, industrial, mechanical and electrical engineers the pair is currently running a highly successful Kickstarter campaign. Their product is WAZER, the first desktop waterjet cutter.

WAZER uses a high pressure water stream and abrasive particles to cut through a workpiece using micro-erosion. Garnet is the abrasive that is used in the cutter, and is non-toxic and easily disposed. The water comes from any tap source and needs to be pumped down a drain after use in the machine.

...

Even after these early Kickstarter units are sold, this waterjet cutter will start at a price point of $6000. This is incredible compared to currently available units. The Kickstarter page looks polished and the design and prototyping work look to be well done. If we give WAZER the benefit of the doubt and assume they can deliver this low cost and high quality product on time this is going to be a huge leap for maker technology.

3M Patents Technology To Print With Flurocarbons

Admin 

New 3D printing technologies are being developed at such a rapid pace that it’s easy to imagine a near future in which there isn’t anything that can’t be 3D printed. We can already print living tissue, and recently a patent application was filed for a 3D printer that prints diamonds. What’s left? As it turns out, there are still quite a few materials that haven’t made it to the 3D printer yet – but companies like 3M are working steadily at getting them there.

Fluorinated polymers, aka fluoropolymers / flurocarbons, may not be as glamorous as diamonds, but they’re an integral material in numerous manufacturing processes. The fluorocarbon-based plastics are distinguished by their high-performance durability and resistance to harsh chemicals and high temperatures. Used in everything from aerospace and defence applications to non-stick cooking surfaces, fluoropolymers are everywhere, except for in 3D printers.

Feature-PTFEThat may soon change, though, as product development company 3M has filed a patent for a new type of 3D printing technology that would allow for the additive manufacturing of fully fluorinated polymers. The technology will mean that complex structures can be manufactured quickly and cheaply, whereas the same parts would often be prohibitively expensive to produce with other manufacturing techniques.

Apocalypse - Survival Prep: Bug-out bag - EDC

chadovision 

Are you prepared?

This Instructable will give you the building blocks to come up with your own tools, kits, gear, and survival items you may need in a survival situation.

Any of the kits to follow can be used alone but as a group you are almost unstoppable.

There are no rules here. You can use anything you wish to make your survival kits. You will be surprised how many ordinary household items you already have that when you put them in one place could mean life or death, or at lease give you comfort when in a bad situation.

I have collected, built and purchased these items to give me a little back up for those times when you need a little extra help out there. When me and my crew of friends and family go off the beaten path they are always l counting on me to have that little item they forgot.

I really hope this helps you build your survival kits, Every Day Carry (EDC), and must needed tools.

DISCLAIMER:

Never put yourself in a survival situation on purpose. Nothing is guaranteed. You could have every survival tool in the world and still not make it out.

High Precision Cardboard CNC Drawing Machine

Dan Chen

After achieving decent accuracy with the 2-Axis Cardboard CNC machine, it gave me the confidence to make the 3-Axis CNC machine with the cardboard. Here are some of my design considerations when designing this machine.

No Glue

Modular design elements / cut outs

Reconfigurable, you can make the bed/stage larger or smaller

Press fit construction

You can use different materials other than cardboard by changing the press fit slots based on the thickness of the material.

Easy to disassemble and reassemble. Easy to repair

A Sucata!

Eis o que estes simpáticos Educadores Brasileiros  nos oferecem, RUTE, uma ideia meritória e que importa divulgar!

Missão 

Nos últimos anos, surgiram vários kits educacionais maravilhosos. Somos fãs de vários deles. Porém, todos eles têm em comum um preço que não é acessível para comunidades carentes para a educação em países em desenvolvimento.

Estes kits custam de U$ 100 a U$ 300. Para uma escola, os valores costumam ser acima de U$ 2.000. Com impostos, taxas e custos de importação esses valores se multiplicam. No Brasil, não é incomum achar brinquedos vendidos em lojas com valores 4 ou 5 vezes o preço original.

Por isso dizemos que RUTE não é um concorrente destes kits. Para quem não pode pagar, nós não somos uma opção mais simples e mais barata, somos a única opção. Outra característica importante é que muitos dos kits atuais não são totalmente open hardware, inviabilizando a cópia sem pagamento de royalties ou licenças. Acreditamos que era necessário fazer algo mais simples, sem técnicas avançadas de produção. Ser rudimentar nos ajuda em 4 pontos:

1 Custo de desenvolvimento mais baixo pois não precisa de molde para injeção de plástico, placas de circuito integrado ou manufatura automatizada

2 Pessoas em regiões afastadas podem produzir seus próprios kits, usando ferramentas e componentes fáceis de achar

3 Possibilidade de usar sucata eletrônica, o que deixar o kit mais barato e a natureza agradece

4 Maior facilidade do entendimento da eletrônica. Para uma criança, uma placa de circuito integrado é muito mais difícil de compreender que um botão soldado em um conector 

MISSION

In the last years, several wonderful educational kits appeared. We’re fans of some of them. But they all have in common a price that isn’t affordable for needy communities’ educational.

These kits costs from US$ 100 – US$ 300. To a school values are usually over US$ 2000. With import and costs and taxes, price grows even further. In Brazilian stores, it isn’t uncommon to find toys marked four or five times its original price.

And that’s why we say that RUTE is not competing with these kits. For those who cannot afford, we’re not a cheaper and simpler option, we are the only option.

Another important feature is that several of the existing kits aren’t fully open hardware, and doesn’t allow replications without the payment of royalties or licenses. We believe that was necessary to do something simpler, that didn’t require advanced manufacturing techniques. Being rudimentary helps us in 4 points:

1 Lower developing costs, because it doesn’t need molds for plastic injection, printed circuit boards or automated manufacturing.

2 People in distant regions can produce their own kits, using tools and components that are easy to find.

3 Possibility of using electronic scrap, which makes the kit even cheaper and nature thanks.

4 Makes understanding electronics easier. To a child, an integrated circuit board is much harder to understand then a button soldered in a connector.

Simple and Durable Hydroxy Gas Generator

Austin Noble 

This instructable is a description of how I made my fifth hydroxy gas generator. Hydroxy gas has been an evolving science for me as I have learned what works, and what doesn't, what you need on a generator, and what you really don't, and that you shouldn't ignite a milk jug full of this stuff at 10:00 PM in the middle of your neighborhood, or you will have some explaining to do. My goal with this generator was to make a device that quickly separates water into hydrogen and oxygen gasses, can be made without advanced tools and is as tough as nails, so that I can throw this thing in my trunk and set it up at a friends house without worrying about spilling caustic fluid, or starting anything on fire. So let's get started.

Não se arranja fácilmente um Isqueiro mais Steampunk que este, mas o que é certo, é que este Projecto é definitivamente algo a tentar, e até, quem sabe, a juntar ao Desenhador CNC ali acima, para fazer uma màquina de corte a Plasma CNC, mesmo que só para chapa metálica ultra-fina, papel, algum plástico condutor, e cartão!

Plasma Cutter From an Arc Lighter

NightHawkInLight 

I recently purchased a few cheap arc lighters on ebay with various projects in mind for them. I hadn't thought of a plasma cutter until I had one in my own hands and saw how it could bore a hole through thin materials that get in the way of the arc. There's an issue with trying to cut things with an arc in exposed air as the material will typically burst into flame. In this project I'll show how to integrate the arc lighter with a cutting head that acts as both a shield against air flow as well as a heat sink to prevent the arc from heating materials to their carbonation point beyond the edges of the cut

Car Wheel Bicycle - The Learn To Weld Project

Mr-Mash 

This whole thing started off with me finding rusty holes in my car and I figured for the cost of paying someone to fix it I could buy a welder and do it myself, seems logical, right?

I was speaking to a friend about needing to learn how to weld and he said why not build a bike (we originally met while I was working in a bike shop and he came in looking for parts for a chopper he was building) he lent me a couple of books by Atomic Zombie, who you should check out, that dude builds some cool stuff.

His website and forum can be found at www.atomiczombie.com

After toying with the idea for a while it seemed like a good one but I was concerned that it wouldn't come out right so it was decided that I would build something a little silly, so, hence the car wheel bicycle was born.

using Inkscape and Gcodetools for CNC plasma cutting

Mr. Hay's Technology

I like SheetCam for generating G-code for a CNC plasma cutter from DXF or SVG drawings, but I prefer free and/or open source programs that students can use on their own computers. Inkscape and the Gcodetools plug-in achieve that.

Version 0.49 of Inkscape will include Gcodetools, but until then we have to extract the contents of the Gcodetools download (using a program such as 7-zip) and put them in the appropriate Inkscape directory (probably c:\Program Files\Inkscape\share\extensions\ on Windows).

Engineering A 3 Wheel Vehicle Chassis

MechEngineerMike  

My university senior project was extremely ambitious. Over the course of a year (2011), myself and three other mechanical engineering students designed and fabricated a complete solar race car chassis including the frame, suspension, hubs, spindles, brakes, & steering.

Its been almost 5 years now but vehicle design is just as fascinating to me today. In retrospect any one of the above systems would have been an adequate senior design project. My decision to attempt all of them together reveals the ignorance/arrogance/ambition of my younger self. In the end we were successful though and I learned a heck of a lot about chassis design. I'm sure there are a few more ambitious university students out there who could benefit from my experiences.

This instructable will discuss the engineering process of designing a custom 3 wheel vehicle chassis. The project consisted of research on vehicle dynamics theory and calculations, 3D modelling, structural stress analysis, designing around human factors, component sourcing, and lots of time spent fabricating.

Worlds Smallest DIY Survival Kit

Akinventor 

I have created what I think to be the world's smallest survival kit. While this kit is certainly not the only thing you should count on, it is very useful and tightly packed. I can say for sure that at lease one of the things would help in nearly any survival situation, if not more. The tape, the thread, and the fire making kit are avery useful. I have not used this kit to do so, but I have made fires from one match and no external tinder many times. Please do not comment below telling me how I will die in the wilderness, I am from Alaska and I always carry more than just this one kit.

Here is what the kit includes:

Fish Hook

Needle

3 feet of cord

Two Matches and striker

Fire tinder

Knife

Compass needle for DIY compass

1 foot of electrical tape

These things can be used with the combination of the outdoors to equal:

Food

Shelter

Repair

Finding your way home

Experimenting with the Pi NoIR prototype and blue and infrared filters.

Following on from my first attempt at building a night vision time-lapse rig, I thought I'd see how the Pi NoIR performs when used with filters. Of course, you get pretty interesting results just using the camera in daylight and without any filtering; as can be seen below images have a reddish hue and infrared reflecting plants appear curiously radiant..
