E desa outra nossa amiga, a Scarlett Jackson, vem esta ideia digna dum Filme de James Bond, uma lente de contacto com display LED!

Um pouco invasivo demais para o meu gosto, mas há situações em que isto vai salvar vidas, de certeza...

3D Printed Contact Lenses with LED Display

Researchers at the University of Washington have announced that they have managed to include an LED display in a contact lens, a breakthrough that could exceed the capabilities of the Google Glass. Still it is not more than a prototype, since by the time this "LED display" has the size of a pixel, but its researchers have already indicated that they will show much more data, as for example the email.

Proto-pasta Announces Addition of Two New Metallic PLA Filaments
Andrew Wheeler

ProtoPlant, makers of Proto-pasta, announced two new materials for its line of exotic 3D printer filament: Stainless Steel PLA and Magnetic Iron PLA.

​Engineered for printability on home 3D printers, Proto-pasta Stainless Steel PLA can be polished or brushed for a brilliant metallic shine, or left unfinished for a cast metal appearance. Great for making realistic terminator replicas or giving prototypes an industrial design feel and aesthetic.

Stove from barrels

Stefan Gales

I made a sketch of the stove so that you see the look on the inside.
With this stove I heat a space of 60 square meters (646 square foot) or rather 150 m (5,300 cubic foot).
If outside is -16 degrees Celsius (3.2 Fahrenheit), inside are 19 degrees Celsius (66.2 Fahrenheit).
The workshop I heat has plank walls of 2.5 cm (1 inch) and polystyrene insulation of 3 cm (1.2 inch). So it is not very isolated.

Making Diesel from Waste Vegetable Oil - Biodiesel

Tecwyn Twmffat

  Maybe if Walt and Jesse had taken to making biodiesel rather than methamphetamine they would have had less trouble with the Mexican cartels, less murders and violence and an altogether easier life? Also a lot more environmentally friendly! There have however been some moments of excitement in my biodiesel career - on one occasion I was raided and interrogated by the Feds on suspicion of processing 'red' diesel into 'white', but fortunately they went away happy that I was innocent.
When I watched Breaking Bad there were quite a few actual similarities like, for example, always being wanting to perfect the product and taking a great pride in it. Some of the machinery in their industrial production plant looked a bit weird and unfortunately there was not enough pipework for it to actually work. It does however give some insight into what it is like to work with chemicals and in many ways making diesel (biodiesel) is a mysterious business and more akin to alchemy than science.

Big/Tiny Variable Dust Separator

Superbender

With my increasing interest in woodworking and the amount of dust created in the process I needed to find a solution for collecting the dust created in my garage without clogging up the filter of my shop vac. There are plenty of solutions posted in the web which vary from buying and assembling commercially available dust separator systems to making your own. Here I am presenting the solution I came up with, that is as usual based on all the good stuff I could find on the web and then some of my own ideas. I went for the simplest possible design which turned out to be able to handle a wide range of machines and dust/shaving volumes with 'Version2'.

2 Brick Forge

squirejoe2

I have been looking for a 2 brick forge design for a while and couldn't find any that met my needs. Most are 1 Brick Forges that are really too shallow for what I want to do.

I am working on longer pieces of 1/4 and 5/16th stock at about 5"-7" lengths.

This is my parts list:

• 2 Fire Bricks 9"X4.5"X3"
• 1" spade bit
• 5/8th spade bit
• 5/16th drill bit
• Cold Chisel
• 36" 5/16 - 18 threaded Rod cut into four even pieces 9" long
• 16 5/16 - 18 nuts
• 8 split washer
• 4 one foot length 1"X1" steel angle stock
• Power Drill

I decided that I needed an 8"x3"X3" chamber, so I marked the brick with a permanent marker.

Micro Engines and Tools Made From Scratch
Nick Normal

 

Primarily working with miniatures, but also exploring solar, steam, and thermoelectricity, I stumbled upon the YouTube channel of Greek maker JohnnyQ90 and felt compelled to share his projects with you.

His engine projects are fascinating for their diminutive size while mostly functioning as desired. His channel description says everything is “made from scratch”…”and a lot of patience!” No doubt. Some of his engines aren’t much bigger than a large coin:

Taiwanese engineer working on the world's biggest CMYKW 3D printer

Alec

Anyone who's ever bought or built a 3D FDM printer, will know that there are currently dozens of models on the market. But despite all the available options you have to consider – complicated or user-friendly, heated or regular printbed, SD-card or Wi-Fi and so on – most of them are fundamentally about heated filament, a single extruder and a limited print size. Various options and printers can result in higher-quality results, in shorter print times or in more convenience, but the fundamentals are largely similar.

And while that might be just fine for most of us, there are always some people looking for a bit more. People like the mechanical engineer James Chang, from Taiwan. Chang had an itch that regular 3D printers couldn't scratch, so he's been working a truly unique and inspiring project for the past few months: the Super 3D Printer.

PieceMaker Factory: A Glimpse Into The Future of Toys?

Marc de Vinck

 

Late Friday night I saw what may be the future of toys, or at least something completely unique at my local Toys’R’Us. Additive manufacturing, often referred as 3D printing, has become common place in the maker movement. However, there is hardly a day that goes by where I don’t meet someone who has no idea what it is, or what it does. Well that’s about to change thanks to PieceMaker and Toys’R’Us.

Electrónica Fácil! E Impressoras SLS mais baratas, Um E-Book da Sculpteo, e Coragem a sério!

LED flasher 2: Hats off to Mr Kurt and LTspice

Mr Kurt, wise commenter of this parish, drew my attention to LTspice.

What a revelation

LTspice is a free version of spice from Linear Technology, and it is delightfully easy to use, intuative, and seems to work rather well.

Note, there is a flasher version 3

Current through component and voltages on nodes can be displayed with a single click on the schematic.

Having messed for ages with my little flasher circuit on the bench, running it through LTspice has helped me think through its limitations and confirm some suspicions I had.

Good thing 1: It oscillated in spice – once I had messed with some values a little.

This is the basic idea of the circuit

My cunning idea (now proved to be not-so-cunning) was to have constant current supply to a capacitor and load it with an oscillator whose load is an LED.

The oscillator senses the capacitor and turns the led on when the supply voltage reaches a high threshold, then off when it drops below a lower threshold.

Providing the LED current is greater than the supply current, it should flash along happily and regulate the capacitor voltage.

SLS 3D Printing Machines Are Getting Affordable

Even the expensive and most wanted SLS machine are getting affordable. Addictive manufacturing is getting more popular among scientist and engineers, who is not buying a 3d printer for research instead making a 3d printer with some unique features that no other current market does.

In no quick time we are hearing some good news about SLS machine which are hitting the market with bang, Ester 3d printer has launched their product in indiegogo at the rate $2500 which comes as unassembled. For those who doesn’t know about SLS machine cost won’t be surprised since the price usually around beyond $200,000, Brandon Fosdick is the genius behind this invention of Ester 3d printer and provides all these parts, hardware, software so that people can upgrade, modify this machine into a better one. This machine doesn’t support material as they accept the powder kind of material to get print.

3D Printing / Traditional manufacturing: Guide to cost efficiency

In this guide, you will find a comparative study between 3D Printing and Plastic Injection Molding. In order to download it for free, all you need to do is fill the above fields.

In comparison with traditional production techniques, especially plastic molding, the advantages of 3D Printing go far beyond Rapid Prototyping or object customization.

Sculpteo’s online 3D Printing services allow professionals and consumers to produce short series in an economically competitive manner.

We conducted a study on cost efficiency through short series manufacturing with the hope to prove 3D printing’s competitive edge. The study’s goal: determine when it’s more cost effective to use 3D Printing (through SLS processes) as opposed to Plastic injection for your production.

Our study first takes into consideration qualitative aspects such as elasticity, resistance and finishes before switching to more quantitative research.

Playful Prosthetic Arm

CobyUnger

I met nine-year-old Aidan Robinson at a summer camp he attended called Superhero Cyborgs. This camp, run by KIDmob, is a place where kids with a variety of limb differences design their own prosthetic and orthotic devices. Each kid's design was impressive, but Aidan's playful ideas really resonated with me. To me, Aidan's ideas were a model for how prosthetic devices could and should be more appropriate, useful, and fun than those typically used for both children and adults.The typical prosthetic arm has a robotic hand or a hook that does not adapt well to a variety uses.

Aidan was born without a left arm below the elbow and has had many different types of prosthetics, all leaving him feeling almost better off without them. Despite these hurdles, and like the resilient and creative kid he is, Aidan adapted extremely well to life with a limb difference and is more active than most kids his age. Because the prosthetic is a part of him, we both felt that he needed a device that accurately reflected his personality and interests.
