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

Um Kit Didáctico, mas acessível, e com a possibilidade de usar material reciclado, ou seja, a grande ajuda tão conhecida dos Inventores...

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

Se quizerem aprender a soldar, ou apenas, ter uma Bicicleta para chamar as atenções, e de que maneira, têem este Projecto incrível, e que até pode ser mais cómodo para as articulações, se usarem Jantes em Plástico, e "pneus" em Espuma de Borracha...

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.
