Making Custom Lenses

Robb

The world of optics and lens manufacturing has traditionally been closed off to non-experts. It doesn't have to be that way. Using rapid prototyping tools like 3D printers and CNC routers, making a lens is easier than you might think.

You can use the technique outlined in this Instructable to make very large lenses, lenses that produce special effects, and sculptural lenses with freeform shapes. You'll need to know how to use a CNC router or have access to a nice 3D printer. With one of the two you'll be able to start making lenses right away.

Long Bed Printed 3d Printer

dmserve

The Long Bed 3d Printer was created to see how much of a 3d printer could be printed. That lead me to design a frame that could be printed on a heated bed, soon discovered I needed a larger build surface. After making a way to accurately control a larger bed, I had the maximum size that the frame pieces could be. By combining different parts I was able to get the main frame down to 9 pieces.

This Printer Can Reproduce Most of the Parts to make itself
Thanks for Checking This Out

Uma Linha Laser, não uma simples mas uma linha toda à volta, atenção Arqueólogos, é o que podem fazer assim:

The DIY Laserline
by slurgXX

I have a project coming up, that needs a laserline, that creates a line over a 3 dimensional object in order to mark and cut it somewhat precicely. I´ve attached some pictures, materials i used ( materials i didn´t use) and some shots after finishing the piece.

But lets get to it, here is what you need to bild the thing*
*( some parts are just what i had around, and can be replaced with other random similar stuff, but we get to that later.)

...E se sempre quizeram imprimir uma Sanita(!) ou um Motor dum Automóvel, cá está a Impressora 3D feita no Texas, onde tudo é maior...

BRUTAL! 
Gosto disto. LOL

Gigabot Proves Even 3D Printing is Bigger in Texas
Tyler Winegarner

After their wildy successful first Kickstarter back in 2013, re:3D’s latest iteration of Gigabot, an extra large 3D printer, is Open Gigabot, which currently has two days left on its Kickstarter campaign. The Open Gigabot files are being released on Wevolver, a social enterprise for open source hardware.
Make: spoke with re:3D Co-Founder Katy Jeremko about the ecological inspiration behind the jumbo-sized printers. She says that re:3D wanted to “allow individuals worldwide to 3D print composting toilets or other human-scale solutions from trash.” The team decided to focus on developing a toilet printer, now known as the Gigabot. (Jeremko mentioned that they later found 3D printing with trash to be extremely difficult!)

3D SOBRE 3D! E Sintratech, não de Sintra, mas da Suiça

Eis algo que vai ser de uma enorme utilidade para quase tudo, porque se vai um dia imprimir em 3D, SOBRE um objecto, não uma placa, mas um objecto qualquer que caiba na impressora!
Por conjugar uma Impressora com um Scanner, a Impressorasabe sempre onde, e como, a superfície de impressão está.

Haverá melhor maneira de reparar tanta coisa, e de fabricar peças de artefactos muito mais complexos do que os de hoje?

Havia a Foto-Montagem, isto será a 3D-Montagem! 
E como aponta aqui Cabe Atwell, da Make Magazine, poder-se-há RETOMAR uma Impressão 3D, parada a meio!

3D Printer That Scans Objects to Print on Its Surface

Cabe Atwell

When it comes to unusual 3D printers and materials, MIT takes the proverbial cake. Students and researchers from the prestigious institution have designed printers that can print food (The Cornucopia and the latest machine to print ice cream), robots (Origami Robot), and even composite bones (CPU optimized designs of soft and stiff polymers).
Now researchers have designed a prototype 3D printer that is capable of locating and printing on objects that are positioned on its printing tray. Trying to print on an object usually involves ‘eyeballing’ the location or using specialized camera equipment to get the precise location. MIT’s solution was to combine the printer with a 3D scanner, making the job a heck of a lot easier to do, especially on irregular surfaces. Not only that, but it works for previously stopped printing projects that would otherwise become useless preformed objects destined for the trash.

Esta é uma Impressora 3D com um nome curioso, Sintratech, não é de Sintra, mas de Sintering, e são da Suíça.

De qualquer maneira, cá vai o Artigo, também da Make Magazine, onde podem ver, no vídeo, porque estas Impressoras 3D, de método SLS, valem a diferença de preço, são mais rápidas, executam peças impossíveis nas mais baratas, as de deposição de plástico fundido, e em plástico que permite criar peças muito mais resistentes!

Sintratec: Affordable Home SLS Printer Coming Soon

Caleb Kraft

Desktop Selective Laser Sintering, or SLS, is a highly sought after item in the 3d printing world. SLS printers print by layering fine powder, then selectively “sintering” or melting it with a laser. Since there is a solid “cake” of powder, no support materials are necessary. Typically these machines are extremely expensive and quite large. Sintratec is hoping to change that.

The Sintratec team currently consists of 3 electrical engineers based out of Switzerland: Joscha Zeltner, Christian Von Burg, and Dominik Solenicki. The three hope to launch a crowdfunding campaign in October to raise enough money to ship at least 60 kit printers. Their current target price is under 3999€ ($5,277), which is considerably cheap for an SLS machine, though still quite pricey compared to your typical FDM printer. However, as you can see in the video above, they are quite different machines.

Arduino, Mindsets, um Cortador de Esferovite CNC, etc.

Um Arduino é sempre bom... Até para enviar mensagens de Texto!

Arduino text'in
ray74 

Key Features:
24 relays controlled by 4 I/O lines!
Cell phone text using your Arduino.

This project hacks a cell phone to text using normally open relays. After investigating cellular modules on the internet I decided it looks not only rather pricy, but also like a possibility that even after I had it working that a cellular provider might not let me put the device on their network. It seemed like a good cell phone hack was in order to make this work for me.

Mindsets, vão lá sempre que possam, está-nos sempre a surpreender, pelas melhores razões, como amostra, eis um Relógio Atómico, Tinta Condutora, para fazerem Circuitos integrados com Marcador(!), e um Controlador programável, para o que queiram, com botões e tudo...

ATOMIC CLOCK

Build your own atomic clock using this incredible atomic clock receiver.
The signal is taken from a clock at the National Physical Laboratory (NPL), which is accurate to within a second in 138 million years!

The receiver drives a stepper motor one revolution per minute, which can then drive a gear train to indicate minutes, hours etc.

A great opportunity to design your own clock.

CONDUCTIVE INK

Non-toxic ink to paint your circuits onto almost any surface for great fun demonstrations of electric circuits.
Teach the fundamentals of circuitry in a simple yet practical way which captures the imagination.

Suitable for LEDs but has a relatively high resistance so not suitable for electric motors.

Here we have a Special Halloween Card Kit which is a perfect demonstration of the technology as well as a great gift idea.

The ink is also available in an easy to use pen.

IQ4

The IQ4 is the latest in our line of easy-to-use controllers. It is simply programmed using the on-board buttons, without the need for a computer. The two high-power outputs can be used to control motors, buzzers, lights and so on. Each output is capable of driving a motor forward or backward with the direction simply set using the reverse button. The analogue input can be used directly with LDRs, thermistors and similar sensors, as well as switches. The input threshold can also be programmed making the controller extremely versatile.

Já vos falei das possiblilidades da Esferovite, ou Isopor, quando se lhe aplica uma camada de Cold Ceramic, fazem-se peças com a resistência do plástico, mas que se trabalham antes, com ferramentas do mais simples que há, um Canivete e Lixa, já fazem o trabalho!

Pois se se juntar a isso, uma Máquina CNC de cortar Esferovite, com Fio Quente, têem a possibilidade de passar as vossas ideias do Computador para o Mundo real, com peças que se podem usar para alguma coisa!

Pois estamos com sorte, Malta, temos este Site incrível, que nos dá todas as Istrucções, em Vídeo e Pdf.

E ainda por cima...

É tudo feito com um Sistema de Mola-e-Parafuso, com Perfis, e peças de Automóvel, que se arranjam ao pontapé, que dá para construírem uma data de outras coisas, porreiramente bestial!

HobbyCNC Foam Cutting Machine

batchelc

Introduction
This article will show you how-to build a CNC hot wire foam cutting machine. Foam is a great building material that is lightweight and inexpensive. With a CNC foam cutter you can quickly build complex shapes including wings and fuselages. The machine works by moving a heated (hot) wire through foam.
The heat of the wire melts the foam leaving the desired shape in the foam. When you are finished you have a "shuck" (unused part) and a "core" (used part). This is the first in a two part series that will show you how to build a CNC foam cutter. The second part will cover the hot wire and hot-wire power supply as well as operating the machine with the software and various cutting techniques.
