$99 palm-sized PocketMaker 3D printer launches on Indiegogo 

While 3D printers do honestly come in all shapes and sizes, the vast majority of models feature roughly the same desktop size – with size differences usually being negligible. While the dream is always to go bigger and wider to facilitate larger prints and more ambitious projects, there’s a lot to be said for downsizing as well. Aside from the obvious benefit of making your 3D printer extremely portable, it also means 3D printing smaller, more efficient objects and optimally using your build volume. Why be tempted to go bigger if smaller means becoming more efficient? If this sounds appealing, then the palm-sized PocketMaker might be something for you.

3D Printed 1:10 OpenRC Formula 1 car

Daniel Norée  

This is the OpenR/C Formula 1 car. It´s the third generation 3D printed OpenR/C car and this time around focus is on simplicity! You can print everything in PLA except the tires which are done in NinjaFlex! Of course you can print it in any material you like but for those that want to print a car but only have PLA at hand, this is the project for you!

This guide explains how to assemble the OpenRC F1 car. If you want to add electronics to make it radiocontrolled another step will be added later.

Raspberry Pi Surveillance Rover (Land Drone)

DavidDrones  

Ever wanted to have a surveillance drone to monitor your surroundings? Of course you have!

Using a Raspberry Pi for the on-board logic, this compact, mobile computer, will create a local port that streams a video in real-time while simultaneously creating Bluetooth sockets to read values sent by a custom android app. The app syncs with the drone and uses user input to send instructions to the drone instantly. This project is fairly difficult to make from scratch, so hopefully the following will make life easier and provide some insight for drone enthusiasts like myself. All the software used for this project is provided. The code used was originally written by myself, but a few lines might have come from other sources. Feel free to modify and share the code to your liking. Please use the information provided responsibly and have fun!

Power in the Apocalypse (How to build a Wood-Gasifier)

tatebullrider 

In this Instructable I will be showing you the steps I used to build my Wood/Biomass Gasifier. It was really a fun project and I would encourage anyone serious about preparedness to build one. Now in case you don't know what a Gasifier is (and don't feel bad if you don't as very few people do lol), they are quite simple, let me explain. Essentially all gasification is, is a form of incomplete combustion, heat from the burning solid fuel creates gases which are unable to burn completely because of the insufficient amounts of oxygen from the available supply of air, it then filters those gasses(which is by weight: 20% hydrogen, 20% carbon monoxide, 50 to 60% nitrogen, and a little bit of methane) And you can really use any kind of Biomass(organic material) that will burn. You can even use things like paper, coal, peat, and lignite. You can then use that filtered gas to run any thing from a generator to a car. So now that you have a basic understanding of what gasification is, lets get down to the build!!!

3D Printed Molds Casting Tutorial: Complex Shapeshertzgamma 

Here is a very easy technique to cast complex shapes in 3D printed molds.

By complex shapes I mean shapes that are hollow, have channels or thin walls etc. Standard techniques usually involve making a negative shape of your object in sand or other material and then pouring the casting resin inside. This method is not something easy to do in a lab and it does not provide the possibility to easily cast shapes hollow from the inside. It also lacks repeatability and consistency in the final object.

It all starts with an idea - you want to make that minion figure from Despicable Me or a copy of someone's toe (why not haha).. Follow the instructable for a simple method to produce soft silicone casts out of 3D printed molds.

The process in 3 steps:

First we create the cast

Then, we mix two silicone compounds (usually or whatever you have) and pour them into the cast - gravity takes over and replaces the air in the mold with silicone

When the silicone cures we extract it from the cast and it's done!

Issues arise when we want to cast a complex object that has many surfaces or cavities.

Lego NXT Laser Engraver

Baybren

 

After seeing a few laser engravers on Instructables and their intricate results I decided it would be worth building my own machine to make some wooden signs and artwork. I also decided I wanted it to be easy to build but still relatively effective at engraving images and that other people would be able to build as well. Thus my goal was to make it cost-effective and simple enough that anyone with some basic electronics knowledge and materials could build it without much difficulty. Initially I was going to use Arduino and almost all 3D-printed parts, but after having some printer issues I figured Legos would make things much simpler and easier to work with, and it's turned out fairly well. It's not industrial-grade and it has some issues of its own, but it's a great way to get started with using and building custom CNC tools, and doesn't require any knowledge of Arduino or soldering.

OSVehicle’s Tabby EVO: Build This Open-Source EV in an Hour
Mike Senese

 The OSVehicle team wants to revolutionize the way the world makes its transportation, and today introduces a new platform that will help bring auto building to the community and individual level.

Named Tabby EVO, the vehicle can be built in just an hour in a moderately equipped workshop. It features an 80v/15 kW electric drivetrain with a range of 87 miles and a top speed of 80 mph. It has a 93-inch wheelbase and can be configured for 2-4 passengers. Its upgraded frame and suspension help qualify it for L6e, L7e, and M1 licensing for street-legal use in Europe and the US, as well as allow it to be used for off-road purposes.

Resin Casting Tutorial - Moldmaking

seeblack

When I started to make my Umi costume, it soon became apparent that I would have to make my own custom molds. You can usually buy or find something to cast common gem shapes, but sometimes the size you need won't be commercially available. In the above pictures, all the front tabard gems, headband gems, and waist cincher gems were made from custom molds using silicone rubber from Smooth-On. (The small ovals and small circle gems were made from a Michael's resin casting tray and a generic $1 paint tray respectively.

Upgrading a CNC milling machine Part 1

stuartChilds

Compact CNC machines have been around for a long time and there are affordable and often well built units available to buy from surplus suppliers and via auction. Provided a machine is of good quality and has not been abused the hardware will likely work for many years to come.

Though the mechanical side may be serviceable it can be a different story when it comes to the software; the machines may not come with their original control computers, if they do this may not boot or may be missing the security 'dongle' for the control software. In addition there have been numerous improvements in motor drive technology in recent years.

We have a Denford Novamill 3-axis mill that came with a rusty old computer that did not boot up. From initial inspection the mill itself looked promising, leaving us with the challenge of connecting a new computer with new software to run the machine.

In this first post we will determine how our machine is wired and bring it up to date with new stepper motor drive electronics, and with a brand new embedded control computer.

Watch Handibot Cut 3D Chess Pieces
Nathan Hurst

The portable Shopbot CNC tool, Handibot, fits on a rotary indexer, churning out extra-large chess pieces from acrylic in the middle of Maker Faire. The environment is loud, and the shop vacs are running almost constantly, but engineer Ryan Sturmer says it’s the perfect environment to demo the tool.

“We have taken the internal electronic and software framework of our tool, and replaced it with something that is web capable, that you can access from your mobile device,” he says. “Your CNC tool will actually have an app.”

It’s targeted at Makers. Shopbot now has open-source FabMo software, a digital fabrication platform for PC, Mac, Linux, and mobile, and Sturmer hopes to see developers building apps for it.

Coflex: Sugru and Duct Tape Have a Baby

ktana

Sugru rocks, but it can be expensive and permanent, duct tape holds the universe together but it's sort of permanent and not at all repositionable, and can be stiff and thick. That's where coflex comes in. Coflex is inexpensive, sticks to itself and you don't have to wait for it to dry or set. Also known as vet wrap, coban, flex wrap, cohesive bandage wrapping tape, sport wrap, and a bunch of other names, it's used in medicine for bandaging, holding things together and a bunch of other uses that aren't official.

Make a Portable WorkstationBenne
After having finished my CNC router (see my other Instructable), my workshop (a small shed in my backyard 3 x 6 m), became pretty full. The only other tools that I can fit in there are a small table saw, a drill press and some small powertools and handtools. So most of my woodworking happens outside. Next to woodworking and CNC stuff, I also like to work on smaller projects with electronics, which requires soldering etc. Since my 'workshop' is pretty full, I didn't have a proper place to work on these smaller projects. So I just moved some of my smaller tools (screwdrivers, soldering iron, pliers etc.) into my bedroom and worked on my electonics projects there. My parents were ok with the fact that I did some soldering in my bedroom, (better than in the kitchen or the living room), but didn't like the fact that my tools were laying all over the place. The table I was doing my work on also became pretty dented and full of glue and solder blobs.

Printing in gel takes 3D printing freeform and enables an undo function

Randall Marsh


The additive layer process of conventional 3D printers means they are usually limited to bottom up fabrication on three axes. The Mataerial printer managed to defy gravity by using a quick-solidifying print material, but now the LA-based NSTRMNT team led by Brian Harms, a Masters student at the Southern California Institute of Architecture, has created a 3D printing process called suspended disposition that gets around gravity by printing objects within a gel. Not only does this allow freeform additive fabrication on six axes, it also enables an "undo" function.

Oogoo na Cozinha!

Ora aqui estão várias peças em Oogoo, experiências da minha Pen&Note, com diferentes cores e proporções de Maizena, Silicone, e Glicerina. 

UMA PEGA

Se quizerem uma desculpa prá Patroa, para brincarem com Oogoo em casa, nada melhor que uma Pega para a Cozinha, como esta, que está ao lado do Bloco-Notas, com a Pen&Note:

Não passa duma Bola que vocês fazem com o Oogoo, neste caso, 1/3 Maizena, 1/3 Silicone, 1/3 Glicerina, e alguma cor duma bisnaga de Tinta de Óleo ou Acrílica.

Quando a Pasta de Oogoo está como Plasticina, fazem uma Bola, depois passam um rolo por cima, fica uma bola ahatada, é só deixar secar cima de algo que lhe dê esta forma, e já está!




MISTURAS, E RESULTADOS

Eis os resultados até agora, de diferentes proporções dos Ingredientes do Oogoo:

50% Silicone, 50% Maizena:
Oogoo rijo, como a borracha das Raspadeiras.

Mais Silicone que Maizena:
Oogoo mais como a Borracha ressalta e estica.

Mais Maizena que Silicone:
Borracha de Apagar.

50% Silicone, 50% Maizena, mais Glicerina:
Uma Borracha mais estilo Espuma de Borracha.

Algodão embebido em silicone, e depois coberto com Maizena:
Uma espécie de Tecido de Oogo, fácilmente moldável, que depois fica com a forma que se lhe dê, com a vantagem de se conseguir uma espessura de 1mm, que se sustenta.  

Para fazerem Bolas Saltitonas, que não achatam enquanto secam, enrolem a bola, bem enrolada, e depois, deitem para dentro de àgua.
