I built a larger 18x24 bed vacuum former first, and then decided that
I needed a mini vacuum former for smaller pieces and for the leftover scrap plastic from the big former. This was a weekend project and it makes great pulls. 










Continuando na senda de pequenas Máquinas-Ferramentas que vos facilitam a vida de Engenhocas, eis agora esta Cortadora a Fio Quente também portátil, e fácil de fazer em casa:




DIY Hot Wire Cutter for Plexiglass, Cardboard and FoamRCLifeOn
This Instructable will demonstrate how you can build your own hot wire cutter, able to slice through foam, cardboard and even plexiglass!
A hot wire cutter works by a wire, often nichrome or in my case kanthal wire, which is heated via electrical resistance. As the wire reach high temperatures it slices through materials by melting it just in advance of contact.

Impressoras 3D em Portugal! E triturar Plástico para Filamento, uma Bicicleta Aquática(!), um Spray-Maravilha, e Curvas na serra de banda

A pedido de vários Engenhocas, cá vão 2 Dicas sobre como e onde comprar uma Impressora 3D, em Portugal, embora suspeite que vendam para o Estrangeiro...

Here's a couple of Portuguese Retail Shop 3D Printers, that might also be available elswehere: 




Por 322 Euros, à data desta publicação, eis algo simpes e barato, para começar a imprimir, é comprar e usar, logo a seguir:



Impressora 3D DaVinci JUNIOR

Ref. imp3DdavinciJr
Nova impressora 3D de filamento PLA (apenas) capaz de criar objectos de uma dimensão máxima até 15x15x15cm.
Não necessita de calibração e imprime até 150mm/sg com resoluções desde 0,1mm até 0,4mm e com software compatível com os formatos .stl e XYZ incluído.  




Um modelo, mas há 4 modelos diferentes, à vossa disposição, eis uma Loja com isso, e muito mais, Filamentos, etc.
Este Modelo, tem outra qulidade, e, já se está a ver outro preço, 750 Euros:



Blocks One  
Se gostam da Ultimaker, então vão adorar esta impressora. Uma impressora com uma óptima qualidade que chega aos 40 microns, e mais impressionante que isso é que mesmo a 200mm/s consegue imprimir razoavelmente bem. Uma vez que tem mesa aquecida, também é possível imprimir com diversos materiais. Para além de todas estas regalias, também já vem montada, é ligar e começar a usar. 









Uma ideia genial para re-aproveitar Objectos da vossa Impressora, de volta para Filamento, e acho que muitos mais Plásticos, eis uma Trituradora por pouco dinheiro e fácil de fazer, vejam como é:






Low Cost Plastic Shredder

joshmt2012 
I have been looking for a way to shred my waste 3D printed parts and support material so i would be able to turn it back into filament. Most of the commercially available ones on the market start at around $500 and having parts water jet to make a shredder can cost over $100 plus all of the bearings and hardware to make it functional. I wanted something inexpensive that would get the job done so i came up with the idea of using an electric hand planer. This is my first iteration of the design and will be updating it to make it work better as i go. The total cost for me was $31.50 but that was because I only had to buy the planer and electrical, with all the other materials the cost should be between $40-50 











Para àguas calmas, vejam só esta bela desta Bicicleta Aquática, que vai ser a alegria deste Verão...
Se lhe juntarem umas correntes de pneu, como as para a Neve, mas com pequenas "pás", e um Leme, podem até pedalar p'lo Rio afora! 





River Rider Water Bike

W1LL7 
Hi Instructables, here is the abstract for the river bike project I've been working on all winter. This is more of a broad guide on how I made it and what I learned then a how-to make your own river bike step by step.
The best way to figure out the project is to watch the video then skim through extra notes I added here. Don't forget that the youtube player has speed adjustment under the gear icon if you need to see something slower.
Project Goals:
Build a bike that I can ride to work on the bike paths then I can ride home down the river.
I do not want to have to swim while using the bike.
The bike can not sink very far into the water because it needs to float over rocks.
Project Mile Stones:
Carve pontoons out of EPS foam.
Shape & seal pontoon.
Weld legs to bike frame.
Constrain pontoons with cables. 









Uma dica bacana do Tech Insider, Line-X vai doravante ser usado numa infinidade de Engenhocas e catrapázios, por Inventores de toda a parte...
FANTÁSTICO! 
MUÁHÁHÁHÁHÁ!




Line-X: This spray makes things almost indestructible
Darren Weaver, Rebecca Harrington and Kevin Reilly
 
There are a lot of ways to break an egg, but if you want to keep it from breaking, might we suggest Line-X? The company created a spray coating that adheres to nearly anything and is very durable. The spray is mostly designed for use on truck and car parts, but is also used on the walls of The Pentagon in the event of a bombing.
The company sent us some everyday items coated in Line-X to see if we could break them, so we gave it a shot.

6 Tips for cutting curves on a bandsaw
ADintheStudio 
 
Cutting complex parts with tight curves safely and accurately on a bandsaw can be challenging, but is fairly easy with some practice, a properly tuned-up bandsaw, and a couple special tips and tricks... enjoy!
What you need:
- A bandsaw
- A thin blade (1/4" recommended)
- Drawing of your cut lines (printed if necessary)
- Supplies for transferring the drawings to your material (see step 2 for methods)
- The material you are cutting into parts (I was using 1" plywood)

PRINTTABLE the Affordable, Attractive IKEA Lack Table Hack to create a 3D Printer

masondrust 
Being interested in 3D printers since 2011 after purchasing a
BFB 3D Touch (Now 3D Systems with the latest model being the Cube Pro costing over £2000) I wanted to build a stable Large build platform 3D Printer for a fraction of the price.
Many Enthusiast's entries into the 3D printer market comes from the purchase of the Prusa i3 kit and in keeping with the good work of the Joseph Prusa design I felt it would be great if the design could be simple.
One of the many drawbacks I noticed was the overall finished look of the DIY kits; i set upon the task of creating a product that not only was affordable and easy to build but one which had style and form a look in keeping with the futuristic possibilities 3D printing brings.

Um sem-fim de Engenhocas tem de fazer do Sótão, Cave, ou Garagem, a sua Oficina...
E trabalhar com Máquinas às escuras é, digamos, ALGO perigoso!
Por isso, é bem-vindo este Instructable, que vos permite ter uma Linha de LEDs que vai iluminar a Sala, e por pouco dinheiro:





Inexpensive garage lights from LED strips
happydupa

Hello all you happy people. Welcome to my first instructable.
This project came about as I recently rebuilt my garage and found myself in need of complete lighting throughout.
I had two main objectives: I wanted bright/even coverage and I wanted to do it as inexpensively as possible.
For a number of reasons I wanted to use all LED lighting for my project but the commercial products were cost prohibitive. At the time of this writing, 4 foot shop lights are going for $40 and higher. I did some research and before long came across inexpensive lighting strips from China. The strips are sold in 5m lengths (16.5 ft) and can be found on ebay for $5-7 each. But how to use them?
After a lot of thought, I came up with the idea of putting them directly onto my trusses. This would give me even lighting throughout and a clean modern look.
I found that one LED strip wasn't bright enough, so I added a second for more light. This is probably enough for general lighting but I wanted MORE POWER and added a third. Why not at this price, right? To give you an idea of the coverage, my garage is 24'x40'. I'm putting lights on 5 trusses and they are 8'6" off the ground.











Para um melhor Qualidade de Vida, eis uma oferta de peso...
O vosso próprio Purificador de Ar, que fazem em casa, porque é Open Source!
Obrigado, Ian van Mourik.






OPEN SOURCE AIR PURIFIER
ianvanmourik 
Hi y’all,
I'm Ian van Mourik a Product Designer from the Netherlands. This instructable is a brain child that I just had to share with the world. Bad air quality causes various health problems and purification solutions are often complex and expensive. The solution is an open source no nonsense air purifier: the OPEN AIR!
This instructable is based on my first experimental prototype of the OPEN AIR.
It’s meant to be a platform to build upon and improve. My personal goal is to test and improve the design and effectiveness. Collectively we can provide new and better solutions. The modular filter design makes it possible to change and test different kind of filters.
This Design is based on a carbon type filter in collaboration with two pressure optimized 120mm 12v PC fans. It´s controlled by an Arduino with a gas sensor and a LED panel for subtle visual feedback.
If you decide to build your own OPEN SOURCE AIR PURIFIER, be ready to roll up your sleeves, because this won't be an easy one. It will include laser cutting, 3D printing, prototyping, soldering, programming and a lot of other bits and bobs. It will be an advanced instructable. But don't let it scare you, because the reward is big, very big! Like thousands cubic meters of fresh pure clean air big.
Good luck! 











Para fazerem algo mais que pisa-papéis e bustos do Yoda, com a vossa Impressora 3D, eis algo de prático e Didáctico, a Roda de Genebra, que transforma uma rotação contínua em  6 passos pausados, algo que pode servir para muito Protótipo.






3D Printed Geneva Drive
robives 
This project was originally posted on notes.robives.com
The Geneva Drive is an elegant mechanism used to convert rotary motion into intermittent motion. There is a YouTube video above as well as on my Instagram feed.
I’ve designed the parts for this project in Autodesk Fusion 360. If you have access to a 3D you can follow these construction instructions to make your own 3D printed Geneva Drive.
Download the STL files from the geneva.zip link above. They should be suitable for most 3D printers. I printed the parts out in a variety of colours of PLA from rigid.ink using an Ultimaker 2. 










Para Churrascadas e Sardinhadas, eis algo que vos poupa uma boa maquia em Carvão, porque o Rocket Stove, do qual esta Grelhadora é uma variante, aproveita todo o Combustível, de tal maneira que nem sai Fumo!
O que também é bom, principalmente para quem sofre de Alergias, ou não quer problemas com a Vizinhança: 






Rocket Grill!
bennelson
 
Want a D.I.Y. way to cook food WITHOUT using fossil fuel L.P. or having to buy charcoal? I know I did. That's why I built a "Rocket Grill"!
This is just one variation of a "rocket stove" - a simple appropriate technology for cleanly burning bio-fuels.
The rocket grill is fired by twigs, wood scraps, wood chips, or nearly anything else you can put in it. It naturally drafts air to maximize combustion. Once the the grill is really going, NO smoke comes out the top, only heat, and the grill really does sound like a rocket!
The grill is designed to not only grill, but also boil, bake, braise, and roast!
Because of the simple design and robust construction, it is nearly maintenance free. Unlike an LP grill, the burner will never burn and rust away to nothingness. (And cost good time and money to replace.) There is no piezo-electric starter or other "modern" technology in the grill, which would be prone to failure.

Cherry- 60€ 3D-Printer

Vulcaman 
Hello, in this instruction, I will show you how to make a 3D-Printer for less than 60€ (maybe the cheapest in the world)
I'm 16 Years old and I made everything by myself.
This 3D-Printer, works with the cheapest motors on the market (28Byj-48), for the electronics I use the Ramps 1.4 . It also has an all metal hotend for around 5€.
Specs:
Buildsize : 10x10x10cm
Travel speed: 20mm/s
Printspeed: 10mm/s
Resolution: 0.2mm 











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.

DIY Smart Follow Me Drone with Camera (Arduino Based)
Imetomi 
Drones are very popular toys and tools these days. You can find professional and even beginner drones and flying gadgets in the market. I have four drones (quadcopters and hexcopters), because I love everything that flies, but the 200th flight isn't so interesting and starts to be boring, so I decided that I will build my own drone with some extra feutures. I like to program Arduino and design circuits and gadgets so I started to build it. I used the MultiWii flight controller that is based on the ATMega328 chip that is also used in the Arduino UNO, so programming was pretty simple. This drone can be connected to an Android smartphone that sends its GPS data to the drone, that compares to its own GPS signal, then starts to follow phone, so if I move on the street the drone follows me. Of course has many failings yet, because I wasn't able to make a proffesional filming drone, but follows the phone, makes a video and also has a ultrasonic distance sensor to avoid the obstacles in the air. I think this is pretty much features from a homemade drone. As soon as possible I will load up a video about a flight, but it is hard to make good quality records with an always moving drone.















Uma ideia do nosso amigo Andrea Biffi, que ainda vou construír cá para casa, uma bacana duma Serra Circular para cortarem, a direito, uma data de placas e pecinhas variadas, que uma Serra de Disco, é um bicho que leva tudo à frente...
E agora, com a possibilade de opcionalmente, ter um Disco Lixador:






mini circular bench saw from scrap [UPDATED]
andrea biffi 
Try to salvage little electric motors from scrap, because you can usually find a way to reuse them. I don't remember where this motor comes from, I've got it many years ago when I used to dismount everything I bumped into, anyway when I found it the other day I immediately pictured a small bench saw to cut metal. Not wood, because motor has a belt and a ratio so that the gear turns at a speed of about 600-1000 RPM which is good for metal, bricks, stones but wood needs very fast speed. To cut these materials you can use a disc grinder, so I bought a pair of discs to apply to my motor.
[UPDATE] I also can apply a disk of sand-paper if needed. To check speed of the disk see last step.














Vejam lá se se conseguem ainda desculpar de não terem uma Secretária decente, (ou uma que aguente muito mau-trato), se o Material para esta, são as Paletes que encontram aos pontapés, por aí!

How to build a Desk from Pallet Wood
StephenS161 
All those pallets that are thrown away....maybe they are worth their weight in gold? Seriously, is that free wood one could avail of? And recycling is good for the environment too!
So I decided to construct a desk from pallets that were going to be thrown away. This desk is intended to house a computer in the future so it has a cabinet with holes that will act as air vents. To add some style, instead of the usual plane panel as a side/leg, a mesh design is being used.
The desktop has holes to allow wires through the surface and conceal them under the surface. Instead of the usual circular holes, the word "DAD" has been routed through so as to also serve as a dedication to my father who introduced me to DIY :)
So, this instructable shows how to create a desk from pallet wood, let's go!

Aerial Photography Super Affordable Kite
hertzgamma
 
Hi everyone!
Here is a very fun and super easy to build tutorial on a kite that will take a camera up in the sky and let you snap those aerial photos you’ve always dreamt of. The kite actually costs pennies to make but is very effective in what it does!
It’s good fun to learn about aerodynamics rather than some rocket science stuff that will bore you to death if you aren’t already an expert in engineering.
So all you kids, makers, creators, hackers, grandmas, grandpas, enthusiasts and of course rocket scientists – follow myjourney and make yourself a kite like this!
P.S. I don’t like much text so feel free to scroll and look through all the pictures – they are really explanatory and give you everything you need to make a kite yourself!
 















Mas como nem tudo no Verão são coisas agradáveis, cá vai este Instructable para se livrarem dos implacáveis Mosquitos!
Uma boa ideia. 



Arduino Mosquito Repeller
webgeeks 
In this instructable I'm going to show you how to build a mosquito repeller using an Arduino. The repeller is in the form of a shield that plugs into the Arduino board and the frequency of the repeller can be changed easily.
This project is ideal if you are going camping or hiking outdoors, this device produces a sound of 31KHz Frequency which acts as a mosquito repellent. The frequency of this device can be adjusted and at 23kHZ to 54 kHz it also acts as a dog whistle. Human ears are not sensitive to these frequency ranges.
You can also view the video below on how to build this project.
