Uma Impressora 3D com Tubo em PVC? E Uma Barraca prás Ferramentas, um Compressor de alta capacidade, a Oficina de Electrónica perfeita, e amolar cafas

Encontrei esta lista de 50(!) Projectos para fazer com Tubo de PVC, e não é que a primeira, é um Engenho de furar?
Ora, penso eu, isto irá inspirar algum Engenhocas a fazer uma estrutura para uma Imprssora 3D, ou  uma Fresa CNC...
Mas se  não, está aqui uma lista de engenhocas para fazerem, desde uma cama para o Gato, até a um Drone submersível, passando por um gerador de Iões negativos, para melhorarem a qualidade do Ar...




50 Things to Make with PVC Pipe

xxlauraxx
Here are 50 projects that'll inspire you to pick up some PVC pipe and get making.
You'll find everything from practical creations, like a drill press and baby gate, to more fanciful projects, like a net gun, dunk tank, and paintball mine.
Whether you're new to working with PVC or you use it all the time, trevormates' PVC 101 is worth checking out before starting your next build. 











É preciso arrumar todas aquelas Ferramentas, e não há espaço, em casa?
Vai tudo prá Barraca, e aqui seguem as instrucções para construírem uma:





How To Build a Shed

darbinorvar 
A shed is great addition to any property. This small garden shed measures 3 x 6 feet (a little less than 1 x 2 meters) so it's great to build if you don't have a lot of space, plus with some smart organization it can fit a lot of things! 








E se precisam de Ar Comprimido, e muito dele, mas sem a Barulheira, têem este Instructable, e ainda por cima, fazem-no usamdo um Comptressor reciclado, isto é, sucateado, dum Frigorífico!






D.I.Y Ultra Quiet Shop compressor from a refrigerator motor (compressor)

botzendesign  
I needed to build a very quiet, higher capacity compressor for my Industrial Design Studio shop, since the one I have is quite loud and does not have the capacity that I was comfortable with for my urethane casting work.
In this Instructable I show you how to build a light duty compressor from parts you can buy on Ebay and or your local hardware store, Home Depot, Lowes, Menards, or a scrap yard, using a refrigerator (fridge) motor compressor. This is not for using heavy power tools or spray painting a car. It's for blowing off parts, maybe airbrushing if you add an air/oil dryer to it or just need some air in your shop for various projects. Add your own optional Motörhead badges too. See the Video below for full details. It's a great companion to this Instructable tutorial.











...E se, por alguma razão, se vão meter na Electrónica, porque não, terem a Oficina de Electrónica perfeita?
Façam assim: 







Setting Up the Perfect Electronics Workplace
bjkayani 
DIY is in my blood and for about 6 years now i have been doing such work. I have a keen interest in electronics work, prototyping, reusing and building. Working is only fun and calming if you have a good workplace with all you will need at arms length. My workplace is build by myself, improved over the years. I am going to share with you my workplace i use for most of my electronics, robotics and hobby work. I hope you will find some of these ideas inspiring for setting up your workplace.













Se se envolveram na Cutelaria, ou precisam de afiar ferramentas de corte, ou lá o que seja que envolva amolar metal, este nosso amigo fez a sua própria Ferramenta de Bancada, e moatra-nos como o fazer, também:








Low Budget Knife-maker's Bench Grinder
antagonizer
 
I've been knife-making for quite a few years, and have always relied on a 1"x24" belt grinder, as well as my 4"x36" bench sander to get the job done. For the longest time, I've wanted to invest in a 2" belt grinder, to make the process easier, but could never justify the massive expense that goes into one. That's when I decided to build one for myself.

Do nosso amigo Andrea Biffi vem mais esta ideia, de  como podem  ter um mini-Engenho, para as vossas Dremmel, para furos como devem de ser furados, sem falhas nem brocas partidas:




 
Cheap precision drill stand

andrea biffi
When I begun to etch my custom pcb I felt the need to improve circuit drill tecnique. I drilled my first circuits by free-hand with my Dremel, but despite it's very fast, it's subject to errors, and it's also dangerous, because the drill bit is very narrow and weak.
I've searched a column drill as the "Proxxon Bench Drill Press TBM 115" but it's a little too expensive. I've found also a vertical stand for Dremel alt 50€, but it was a model with a single metal column as rail, similar to the most you can see with a "drill stand" search, and it had a low precision in horizontal movement of the bit. In fact you felt the head moving of about a millimeter, which is a lot when your bit is so narrow. So I decided to build it by myself.







E ainda fora do alcance do Público em geral, eis uma Impressora...
5D!
Mas bnão se assustem, que é uma Impressora de Filamento, com um Extrusor normal, mas que pode inclinar a placa de deposição, em 2 eixos, e daí 5D, ou mais exactamente, 5 graus de liberdade, no movimento.

O que isto traz de muito útil, é que esta máquiina imprime não só em camadas planas, mas em camadas CURVAS, o que para além dum sem-fim de usos possíveis, e do fim das "escadinhas", significa sobretudo, Objectos com um grau de resistência muito maior...
Por serem feitos seguindo as Linhas de Força exercida sobre esse Objecto, tal como os Edifícios, que seguem a arquitectura da maior força com o menor Material.





 
3D Printing is So Last Week...Say Hello to "5D Printing" at Mitsubishi Electric Research Labs!
Clare Scott  
 
We all know what 3D printing is – obviously. (If you don’t, here’s a handy overview. Welcome, newcomer.) We’ve also explored 4D printing, which involves printed objects that mutate and morph into different shapes when exposed to an outside stimulus such as light, water or temperature changes. So what’s involved in 5D printing? Printed objects that levitate? Printed objects that teleport? Time-traveling printed objects?!
Well…no. You can 3D print a TARDIS, but you still can’t make it travel. 5D printing is simply another name for five-axis additive manufacturing, and while it may not be as exciting as teleportation, it’s still pretty cool – and useful. The term “5D” as applied to five-axis printing is being used by Mitsubishi Electric Research Laboratories (MERL), the North American subsidiary of the multinational corporation’s research and development branch. They’ve been experimenting with a print bed that actually rocks back and forth on two axes, creating a fourth and fifth axis as a result.
What this means for the final printed part is that instead of being created as a series of flat layers, the layers are curved. William Yerazunis, Senior Principal Research Scientist at MERL, describes the advantages of this process as applied to a pressure cap. A cap printed using standard 3D technology will be quickly ripped apart along the adhesion lines when pressure is applied, he explains. But if that same part is printed with the 5D method, curving the lines where the maximum stress will be applied, the part will be three to five times stronger – and will use 25% less material.

Motoretas fantásticas! E um Churrasco numa Lata, regar a Horta, e furar Esferas

Esta Motoreta eléctrica pode-se levar para o Comboio, para o Autocarro, para o Cacilheiro, etc.
Podem até levá-la para o elevador, e guardá-la em casa!
E já anda cá em Lisboa, por isso, deve-se vender em todo o lado. 



E há uma gama de Veículos desdobráveis que podem escolher, como uma versão de motor de combustão, bicicletas, etc:
 

Folding Mopeds, Folding Tricycles and Folding Bicycles DI BLASI

Since 1974 we produce folding mopeds, folding tricycles, folding bicycles, to be used as auxiliary vehicles in conjunction with cars, boats, motorhomes, light aircraft, and in general for leisure activities.
Our mopeds are the ideal motor vehicles to bring in the car boot to be used as alternative means of transport to beat traffic jams; or on boat or on motorhome to increase mobility on holidays. They are indispensable to people who intend to carry out “Designated Drivers Services”.

Our tricycles have wider possibilities of use than normal tricycles because they can be carried on other vehicles and then used away from home. Therefore our folding tricycles increase mobility and autonomy of people that usually ride a tricycle.
Our bicycles, in spite of the large wheels, have very small dimensions when folded and light weight. Riding is comfortable; frame is stiff and sturdy. They are the ideal pedal vehicles to use in conjunction with train, car, etc

A feature common to all our vehicles is that they can be folded or unfolded in a very simple and fast way: not more than 4 seconds, without tools and nothing to screw or unscrew.
The technical solutions that we used in our vehicles have been always in the van and always in the aim to make quick and easy their folding and unfolding, to reduce as much as possible their dimensions when folded, to reduce their weight while maintaining strength and safety, to offer ride stability and comfort.

Here are some of our innovative solutions: frame shaped as an articulated quadrilateral, folding pedals, automatically folding handlebars, three-dimensional folding mechanism of the tricycle, use of a variety of materials to give to the frames the maximum rigidity with minimum weight, etc.
