3D Printed Lathe

iccycold3000  

First off, I am a sophomore high school student who actively participates in FTC Robotics representing Shark Beta Team #10088 and FatherBoards Team #10087. The goal of our robotics team is to learn as much as possible before graduating and going off to college. One crucial skill everybody on our teams had the desire to learn was how to manually lathe parts our self instead of sending the files for somebody else to machine them for us. This was where the idea of building my own lathe came in. As our school did not want to purchase a full-size lathe or for that matter allow students to operate a full-size lathe; the only other option was to build a miniature one myself. The major challenge of this project was that because all of our funds go straight into our robotics program and purchasing parts, the lathe had to be constructed out of existing parts in our lab, or the parts needed to be made personally (this is where the idea of 3D printing the lathe itself came into play. Another major challenge of this project was that the lathe needed to be relatively precise and accurate so that the final parts could actually be used on our robots. Those were the main challences I was faced with and I believe I did a relatively good job at solving these. If you do decide to build this you will find how percise and accurite it is despite it being 3D printed. So lets get to building!

MARAVILHA!!!

600 Watts! 

MUÁHÁHÁHÁHÁ!

Eis um Motor Brushless, que vocês podem construír em casa, se tiverem uma Impressora 3D à mão, ou puderem imprimir estas peças nalgum lado, nalguma FabLab...

Usa o Arrenjo Halbach, de que já falei algumas vezes, e é fácil de montar:

600 Watt, 3d-printed, Halbach Array, Brushless DC Electric Motor

TheGoofy 

This is a very powerful, 3d-printed brushless DC electric motor. It has 600 Watts, and performs with more than 80% efficiency. The main components like rotor and stator can be printed with a common FDM-printer. Magnets, copper wire, and ball-bearings are ordinary components. The magnets of the rotor are arranged as Halbach Array. The motor runs with a standard ESC widely used in different RC-applications (plane, drone, car).

How to Make Colour Changing Paint

SFXC 

In this tutorial I am going to teach you how to make a colour changing paint. On this occasion, I have chosen to create a paint that changes colour with temperature (thermochromic).

There are so many applications in which thermochromic coatings can be used. Some of these include, colour changing t-shirts, colour changing posters, colour changing birthday cards, promotional items and educational products.

Mais Diversão, para Engenhocas novos e velhos,  eis como fazer Flubber, em casa, mas sem utilizar Bórax, que não há à disposição em todos os Países:

No Borax Or Starch Flubber/slime/putty

Igioteno 

I've been looking for a no starch or borax flubber for a long time

Some recipes had tide, cornstarch, lotion, clear glue and other ridiculous ingredients

Today, I found a recipe on YouTube on flubber and sounded very believable

I tried it out and a total fail

I then viewed the videos comments and one said just use glue, eye drops and baking soda

I tried it out with using the same ingredients in the video and the same ingredients the comment suggested it turned out great

But it smelled horribly like bleach and it was very wet

It was also very airy and not that stretchy 

So I just used the recipe the comment suggested

E vamos dar as Boas-Vindas a este nosso amigo Romanurshuak, que conheci através dos seus Vídeos no Youtube, e em boa hora lhe sugeri que fizesse também Instructables, pois cá está este, para aproveitarem Garrafas de Plástico, com esta magnífica Engenhoca que as desfia, em rolos que podem aproveitar para vários fins:

How to Make a Plastic Bottle Cutter / Tutorial

romanursuhack

 

How to make a rope out of a plastic bottle?

We often need a strong wire or rope at rest or at the cottage. For example, you need a linen rope, and there's nothing suitable at hands. Don't worry! It is possible to make a long and strong rope out of an empty plastic bottle.

Soldar, sem solda? E um Computador a 9 Dólares(!), uma Injectora de Plástico para Fabbers, e Alívio para a Dor, mais uma Câmara de Infravermelhos

Eis como fazerem algo em Electrónica sem as chatices do Fumo e da Solda...

E ainda ficam com uma ligação à prova de àgua!

É bom!

Solder Sleeves
Solder, heat shrink and waterproof your splices in one operation.

This is the easiest way to make soldered splice in your wiring. It is our favorite way to extend the wires on stepper motors.
This part combines a low temperature solder ring inside a piece of clear heat shrink tubing. It also has rings of hot melt glue at each end. You strip each wire, insert one from each end and cross the stripped ends inside the solder ring. You then heat the tubing with a heat gun. The solder and glue melts and the tubing shrinks. You get a reliable, insulated, waterproof and soldered connection in one operation.
It is also great when you need to fan out one wire to several wires. This often happens when you have one ground terminal, but four wires coming to it. Place the four wires in one end and one in the other end.

Um Computador por 9 Dólares? 
Com ligação Wifi, e gestão de Bateria?
Sim, se só precisarem de computadorizar uma Engenhoca, ou terem um Smartphone ou Tablet feito à vossa medida, porque este liga-se a um Televisor, ou Écran de Smartphone, com Monitor é mais caro.

Next Thing Co. Releases “World’s First” $9 Computer

David Scheltema

Snuggly situated in an industrial section of Oakland, CA is Next Thing Co. a team of nine artists and engineers who are pursuing the dream of a lower cost single board computer. Today they’ve unveiled their progress on Kickstarter, offering a $9 development board called Chip.

The board is Open Hardware, runs a flavor of Debian Linux, and boasts a 1Ghz R8 ARM processor, 512MB of RAM, and 4GB of eMMC storage. It is more powerful than a Raspberry Pi B+ and equal to the BeagleBone Black in clock speed, RAM, and storage. Differentiating Chip from Beagle is its built-in WiFi, Bluetooth, and the ease in which it can be made portable, thanks to circuitry that handles battery operation.

Ter a vossa própria Fabriqueta na Garagem, passará certamente, mais cedo ou mais tarde, por terem uma Máquina de Injecção de Plástico, para os vossos Projectos.

Pois aqui vai uma que podem fazer em casa, baseado no Ilustre trabalho da casa Gingery:

Make Your Own Injection Molding Machine

John Hannon

Tried, true, and totally doable. Start cranking out solid thermoplastic parts.

Sometimes there’s a tool you want to buy, but you can’t justify the cost. In that case, why not make it? For me, a plastic injection molding machine fell into that category — and it turns out they’re not hard to make.

I wanted to make solid plastic parts for some of my amateur science experiments. There are a number of ways to make things out of plastic, each with its advantages and disadvantages. Often just cutting raw material to the desired shape works best. Some plastics can be cast by pouring a liquid resin with hardener into a mold (see “DIY Rotocaster,” Make: Volume 41). Vacuum forming works well for making things out of thin sheets of plastic (see “Kitchen Floor Vacuum Former,” Make: Volume 11). I considered making a 3D printer, but for the few plastic parts I envisioned needing, it wasn’t worth the time and money.

Plastic injection molding has been around since thermoplastics were invented. It’s a great way to make many copies of a part quickly, and what I like best is that it’s easy to reuse old plastic objects to make new ones.

So I built an injection molder based on the plans in Vincent R. Gingery’s book Secrets of Building a Plastic Injection Molding Machine. David Gingery could be considered a forerunner of the Maker Movement — he and his son Vincent have written a whole series of books on building tools for the machine shop.
