New Guide: Minecraft Inspired Epoxy Resin Torch Lamp with Touch Control

Check out the newest project tutorial from Erin St. Blaine: make an epoxy resin Minecraft-inspired torch lamp. This lamp has a strand of warm white fairy lights embedded right into the resin, making a lovely starry glow effect. Adding a Circuit Playground Express underneath powers up the lamp with 10 programmable NeoPixel LEDs. The included MakeCode downloadable code makes the lamp flicker like a torch for a really beautiful ambient lighting effect.

From the guide:

Make your own custom Minecraft-inspired Torch lamp from epoxy resin. Embed a strand of fairy lights inside, and set it on top of a Circuit Playground Express. The onboard NeoPixel lights provide a lovely, flickery torch effect. This gorgeous lamp glows from the inside out.

Add a piece of shiny copper tape to the base, and you can change light modes with a touch of your finger. Capacitive touch control is just like magic!

We’ve provided a simple 3d printable base model, or you can get creative and design your own display mount. We made ours look like Viking Dragon Ships to go with our Dragon Wall Sconce, and now we sail into sleep at night with fiery dragonish gargoyles watching over us.

3D Printed Surgical Mask Strap Adjuster #3DPrinting #COVID19 @Thingiverse

Thingiverse user Suraky has remixed a wonderful surgical masy tensioner strap. For those masks with longer straps, they may not fit over the ears of more petite people without sagging or they be too tight wearing for an 8 (or 16) hour shift. With this strap holder design, the straps are fully adjustable to get a custom fit on a wearer.

This remix is identical to the original designed by Marslam, but with a hole punched out in the middle portion of the strap to save material and print faster.

This thing has been reviewed and approved for use in a clinical setting by the NIH (US National Institute of Health)!!! https://3dprint.nih.gov/discover/3dpx-013410

Intended to be used to hold the elastic straps of a surgical mask, to relieve the pressure of those on the ears. Apparently wearing a surgical mask all day can be hard on the ears.

The maker also writes on April 5th that, in one week, they’ve personally produced over 1300 straps, with 1215 have gone to a few hospitals in their region where they seem to be really appreciated. A volunteer group that they’re contributing to in the Vancouver BC area has delivered over 3300 straps.

So I’ve been trying to figure out why my particular remix version of the ear saver strap has suddenly become very popular, with over 14,000 downloads in the last day. I think I’ve figured it out – It’s probably due mostly to a certain Scout who’s good deed story truly went viral with over 200k shares on Facebook – that post included a link to this page. Thanks to him the ear saver idea has been seen around the world and thousands of people are printing them. I’ve added a screenshot of his story to this page ?

The Maker Movement Unmade? Part 2: The Roots of the Maker Movement

With the shaky ground that Maker Media (now Make: Community) stands on, this author was prematurely ready to signal the end of the maker movement. However, we have already received feedback from a number of people in the world of open source hardware who suggest that, while the Make: brand may have run into issues, the larger movement it still thriving. We will provide those comments in a follow-up article as a means of diagnosing the current state of the maker community.

Before we get into the future, however, it’s worth looking at the history of the hacking mentality and makerspaces. Depending on how far back you want to go, we could back to the 19th century and Mechanics’ Institutes, which joined libraries, labs and lecture halls. Funded by industrialists, these facilities were meant to provide the working class with a place to gain skills that would aid them in the workplace.

This sort of acceptable form of tinkering, however, seems to be part of a lineage distinct from the sort of unauthorized hacking that would play an important role in the creation of makerspaces much later. As broken down by author “Maxigas” in the Journal of Peer Production, we can distinguish between more-or-less sanctioned makerspaces (or “hackerspaces,” as they were earlier called) and unsanctioned hacklabs (the terms used by the author only to keep the two traditions separate).

Hacklabs blended different movements that developed from the 1970s. In Europe, this included the leftist autonomous movement, which developed with the idea that the working class could create its own power structures separate in response to the State and capital. Communists and anarchists within this fight appropriated physical spaces and real estate to challenge the establishment, a practice known as squatting.

Also in the 70s, the miniaturization of electronics enabled budding tech enthusiasts to computers from kits, like the Altair 8800. Inspired by phone phreaks who experimented with public telephone networks a decade before them, hackers worked individually or often in clubs to program their own software with a philosophy dedicated to the freedom of information and sharing of knowledge.

With the development of technology, another activist tradition developed nestled in the roots of squatting, but dedicated to intervening in cultural spaces. The practice of culture jamming emerged as a form of media activism characterized by pirate radio stations, then video broadcasts and eventually internet-based works.

Maxigas describes the emerging ideology in this way: “Many media activists adhered to some version of Gramsci’s theory of cultural hegemony, taking the stand that cultural and educational work is as important as directly challenging property relations. Indeed, this work was seen as in continuation with overturning those property relations in the area of media, culture and technology.”

In turn, squatting and media activism blended, as squats served as urban hubs for internet access as well as locations to orchestrate culture jamming. These became hacklabs, which emerged roughly between 1995-2005. An interesting example is Italy’s Ultralab, established at the occupied fortress of Forte Prenestino in Rome.

Whereas these sites were dedicated to a countercultural mode of living and challenging society, Maxigas describes hackerspaces (later also called “makerspaces”) as less subversive than hacklabs, as the concept of hacking became institutionalized (like the creation of the Electronic Frontier Foundation) and more integrated into mainstream society. An example of an early second wave hackerspace, would be C-base, founded in 1995 in Berlin as a community center for free internet access.

By the late 2000s, hackerspaces had proliferated extensively, with lectures around the world, as well as established media, inspiring this proliferation. In 2007, Cologne’s C4 hackerspace gave a talk called “Building a Hackerspace,” which inspired “Building Hacker Spaces Everywhere: Your Excuses are Invalid” the next year in the U.S. Hackerspaces.org was founded in 2008, with 72 hackerspaces listed.

Maxigas summarizes the formation of hackerspaces by saying: “the emergence of hackerspaces is in line with a larger trajectory in the hacker movement, which gradually has gained more institutional structures. The turn towards the physical (mainly through utilising micro-controlers) marked the point when hackerspaces became widespread since development and collaboration on such projects is greatly facilitated by having a shared space. While most discourse and innovation in the community was focused on the organisational form rather than the political content of hackerspaces, such less defined and more liberal-leaning political content allowed the movement to spread and forge connections in multiple directions without losing its own thrust: from companies through civil society to a general audience.”

At the same time, the philosophies of hacklabs and hackerspaces/makerspaces are quite different. Hacklabs were born out of a tradition of leftist activism and, at least according to Maxigas, see inclusion of women, sexual minorities and the disabled almost as inherent to the creation of the space. Whereas hackerspaces/makerspaces have tended to be made up of male, well-educated, white and more affluent members with a more narrow philosophy focused on freedom of information and innovation, rather than challenging the status quo. At the same time, due to their integration into society at large, hackerspaces have proliferated more widely than the more societally challenging hacklabs.

The creation of MAKE: Magazine in 2005 seems to lay at the intersection between second- and third-wave hackerspaces. Perhaps it represents the conclusion of the second and beginning of the third wave, which included the introduction of the term “maker”, the launch of Maker Faires, and the media frenzy that coincided with the introduction of 3D printers, microcontrollers, consumer drones and more.

So, we might refer to this third wave, in which hackerspaces were commercialized and branded, as the “maker movement.” We will look at the commercialization of the maker revolution more in the next part of this series and explore the extent to which that commercialization may have played a role in the unmaking of certain portions of the maker movement.

Wikifactory Partners with Fablabs.io, Introduces New Workflow Features

All-in-one workspace Wikifactory, a social platform for collaborative product development, has been pretty busy this summer, first releasing its beta platform and then launching the Docubot Challenge. Now the startup, which was established last summer in Hong Kong, has more good news to share – during its keynote at the recent FAB15 conference in Egypt, Wikifactory officially introduced its new Projects.Fablabs.io site to the global Fab Labs community.

The conference, which was titled “Collectively Independent” and ended a few days ago, welcomed members of the over 1,600 fab labs around the world to Egypt, where they could meet to discuss, collaborate, and share about innovation, technology, and digital manufacturing. Fab labs provide people with a place to invent, create, and learn – they bring their ideas, and fab labs provide access to an environment with advanced technology, materials, and skills so that makers can get busy making.

Fablabs.io is the official international online community for fab labs – it’s an open, online social network where artists, educators, engineers, fabricators, and scientists, from over 40 countries and ranging in age from 5 to 75, can discuss their projects. Soon after Wikifactory was launched in 2018, the startup wondered how it might be able to support the Fablabs.io community.

“That’s why we started working on a new Projects site that uses Wikifactory’s infrastructure to allow Labs around the world to collaborate more effectively in product and hardware development,” Wikifactory wrote in a press release.

The platform’s new partnership with Fablabs.io, which was announced at FAB15 by Wikifactory co-founders Christina Rebel and Max Kampik, means that fab labs around the world are able to not only document, but also share their projects via the Wikifactory-powered Projects.Fablabs.io site. This new site will make it possible for global members of the fab lab community to collaborate in a communal online workspace, which combines “the essential tools for online product development” so that communities, teams, and individuals can receive support and also use functionalities, such as an issue tracker and a version controlled drive, to their best advantage.

But the new Projects.Fablabs.io site isn’t the only news that Wikifactory is sharing. The platform also recently launched some new features to help improve its workflow for users.

Wikifactory launched three new features that will make it even easier to collaborate with distributed product development teams – a Version Control System, Time-travel, and Conflict Resolution.

“Both from an insiders and an outsiders perspective, it’s extremely useful to be able to track the evolution of a Project. This has influenced the design of our Version Control System, inspired by git, but designed for a product development environment,” Wikifactory wrote in a press release.

“Moving away from the command line but considering the same methodology, whatever changes you make to a Project in your own session of Wikifactory remain a local save to your computer until you click Contribute. Every contribution must have a title and a description to send your local changes to the global servers, and when they do, they get logged in the History.”

Version Control, which is “all about managing contributions” between product developers, makes it easier to browse, visualize, and download older versions of your existing files, while the Time-travel feature lets you find a specific version of an older file – such as one before a change was made that you’d like to do unmake. Both of these features allow users to browse through all the versions of a file on Wikifactory.

The visual Conflict Resolution feature obviously lets users resolve conflicts that may arise during product development, such as when a file was deleted by one person while another was modifying it, or if two different collaborators changed the same 3D file. The new feature helps you figure out which changes should stay, and which should be ignored.

“After implementing the conflict-resolution flow, we know this will pave the way to develop functionalities such as forking, merging, branches etc., which are all things we want to add, as we believe they will improve open/distributed collaboration for product developers,” the press release states.

To learn more about these new features and any other developments, check out the Release Notes category on the Wikifactory forum.

Make All the Things Part 2: Ring Creation and Casting a Wax Ring, Part 1

A curious mind and a makerspace results in interesting potential. Previously I had explained my intention to create a ring with the materials in my local MakerSpace of Pumping Station One. The last month was dedicated to a bunch of preparation and learning the process. It has been an immense experience that is still continuing, but I will inform everyone about the first developments of this project and follow ups as needed. 

Original Ring Design

Firstly, I was curious and wandering around Pumping Station One and learned about the Small Metals Area. I just saw the material there and realized what I could do almost instantaneously. I am a firm component of being able to create items for oneself. It is a very empowering mindset to realize that we can do things for ourselves. Coming up with an idea and driving it to completion is a great feeling and experience. Honestly, it is one of the best feelings I get within this world. But let’s stop my geeking out, and let’s get into the details.

I wanted a lion ring. I then put in substantial effort towards this goal. To create this ring I utilized carver’s wax initially for the body of the piece. Then I found a 3D printed lionhead online that I thought was stylish. This then was used for the front facing design of the model. I attached this onto the ring body with sticky wax in a uniform manner. This then created my prototypical design for a ring. The majority of the work done in this stage was dedicated to sanding, as well as molding the ring, to the specific weight I wanted to use. This work took a couple of days of crafting, but now that I understand the process more, it will take even less time than the next time I want to do this. 

Kiln

The next part of this project was filled with lots of hot wax and continuous failure. Sprues of hot wax are needed in terms of attaching a model. This model is plastic and wax, which means that it will be burned within a kiln for metal creation purposes. Chemistry is a fun thing, but I digress.

The sprues must be attached in almost a tree-like structure in order for an item to be cast from plastic or wax into a metal such as silver. This tree structure is placed in a container. In order to cast this, we utilize silicon powder. The silicon powder is weighed in terms of a conversion sheet that a jeweler would use. Then it is mixed with water in order to create a gel. This gel is placed into the aforementioned container and it is left there until it hardens. Once it hardens the container is prepped for placement within the kiln. Mind you, a kiln temperature is around 1500 degrees Fahrenheit. So it is indeed a dangerous process if one is not careful.

Ring After

Once the container is taken out of the kiln, it is now important to understand the conversion of plastic or wax into metal. The tree like structure built is now flipped upside down. A metal of a choice is also melted at a very high temperature. Again, high temperatures are dangerous. Fortunately, I had the help of people at Pumping Station One. This metal is then poured into the container that was taken out of the kiln. The molten metal travels down the tree-like system and it effectively burns the plastic and wax. The silicon powder essentially holds the piece in place and creates a barrier so that the material does not dissipate and lose form. When the molten metal cools down, the container then may be taken to a water bath for cooling. This then concludes the first part of the process. What is needed after this is post-processing, and I will tackle that in a new article.
