    1. I consider Valentines 'designer' typewriters, and generally overrated. If you want to write on an Olivetti, I'd go for the Lettera 22/32/DL. The Valentine is based on the Lettera 32, so the mechanical part is solid, but the Valentine is not as well-balanced as the 32. And about ten times more expensive.

      Me starts thinking about cornering the market in Lettera 32s and 3D printing Valentine cases to put onto them...

    1. ultimately dissociation doesn't really happen it's um it's a model i think it's a an accurate a very useful model but the best way i can i can describe this is using the analogy of going to a 3d imax cinema

      for - metaphor - analogy - dissociation - Bernardo Kastrup - to - 3D imax cinema - localize Rupert Spira - terminology - dissociate - Bernado Kastrup - terminology - localize and contract - Rupert Spira - universal consciousness contracts to finite human consciousness - question - meaning of dissociate - Bernardo Kastrup

      metaphor - analogy - dissociation - Bernardo Kastrup - to - 3D imax cinema - Rupert Spira - At 3d Imax cinema, we wear a pair of special glasses - that make the otherwise fuzzy image to acquire a 3rd dimension - In the same way, our raw universal consciousness is like the fuzzy pattern we see on the 3d Imax screen when we DON'T have any special glasses on - When we perceive and think, it is like putting on the 3D glasses in the Imax theatre and suddenly we see objects with great clarity - Spira talks about universal consciousness "localizing" within its own activity - in the form of a finite mind of a human being

      question - meaning of dissociate - Bernardo Kastrup - Does Kastrup mean that we infinite / universal consciousness dissociates from itself into the finite human consciousness? - answer - It appears so, as at time 45:50, Spira summarizes Kastrup's views on dissociation

    1. James Norris is the owner and operator of Ex Nihilo 3D Print and Design in Spring, Texas. He has always had a fascination with figuring out how things work and seeing if there was a way it could be better. In late 2016 his wife, a burgeoning writer, purchased their first typewriter. He soon became obsessed with all the amazing parts and mechanisms. From there the typewriter collecting began.​From the first Olympia, to an inherited Olivetti, to his first Selectric, and so on.While repairing these machines he realized that there where a few setbacks. The most immediate being parts availability. So armed with his 3d printer he designed and printed his first part. A Selectric cycle clutch pulley in mid 2021. After showing the 3d printed part to some like minded individuals he was happy to learn that they were as excited as he was. He loves to design new parts and accessories to bring these typewriters back to life.James is thrilled to be working with Philly Typewriter, and looks forward to helping with your current and future parts needs. James lives in Texas, is married with two children.

    1. Found this webpage for a 3D brain model when someone (maybe frymatic?) mentioned a region of the brain I was having trouble imagining.

    1. kons-9 is that it combines the power of a software development IDE with the visual tools of 3D graphics authoring system. It does this by being implemented in Common Lisp, an object-oriented dynamic language which provides powerful facilities for exploratory development and rapid prototyping within a live interactive software environment

      IDE + 3D + Lisp = Unique features:: * software development IDE with visual toold of 3d graphics authoring system * unlimited extensibility (no distinction between developers and end users)

    1. It’s almost something of an arms race, where the Nerf internet community one-ups each other by making their toy blasters shoot more foam faster, farther, and more accurately, whether to show off or to perform that much better in an actual game of Nerf. And while Hasbro is clearly taking some notes from the upstart maker community, 3D printers in particular are giving makers an edge they’ve never had before.

      This is the classical story of the open source challenge to an incumbent / dominant actor in a market. In this case it's about Nerf and toy blasters. The interesting bit is that this was hardware-led revolution (3d printing); and the open source spirit is optional - chosen by some actors, but not others.

    1. “The CSAIL team has taken multi-material printing to the next level by printing not just a combination of different polymers or a mixture of metals, but essentially a self-contained working hydraulic system,” Hod Lipson, Columbia University engineering professor and co-author of Fabricated: The New World of 3-D Printing, told CSAIL. “It’s an important step towards the next big phase of 3D printing — moving from printing passive parts to printing active integrated systems.”

      「 CSAIL 团队将多材料打印引入了下一个水平,不仅是打印不同的聚合物或金属混合材料,而且在根本上还是一套能独立运转的液压系统。」哥伦比亚大学工程学教授Hod Lipson 说,「这是进入 3D 打印下一重大阶段的重要一步——从打印被动分散的部件变成打印主动整合协调的系统。」Hod Lipson还是《Fabricated: The New World of 3-D Printing》的作者之一。

    2. “Our approach, which we call ‘printable hydraulics,’ is a step toward the rapid fabrication of functional machines,” Daniela Rus, one of the research paper’s co-authors, told CSAIL. “All you have to do is stick in a battery and motor, and you have a robot that can practically walk right out of the printer.”

      「我们把我们的方式叫做『可打印的液压装置』,在快速制造功能机器方面又迈进了一部。」这篇论文的作者之一Daniela Rus 告诉 CSAIL ,「而你要做的只是插入电池和发动机,你就拥有了一台差不多能正常行走的打印机器人。」

    1. 3 Steps for Licensing Your 3d Printed Stuff by Michael Weinberg

      I found this to be a very interesting article, exploring the line between copyright and licensing of physical objects vs. the code (or digital file) used to create the object. This paper delves into a range of questions - what is being licensed, what is copyrightable, what is covered under a patent, what is a creative work, what is a functional work. Although this paper was published in early 2015, the content remains relevant now. (June 2020 Cohort CC Certificate)

    1. ALA created a resource list to help libraries develop policies for 3D printer use

      ALA creó una guía para el desarrollo de políticas sobre impresión en 3D de armas.

    1. Surface/Interior Depth-Cueing Depth cues can contribute to the three-dimensional quality of projection images by giving perspective to projected structures. The depth-cueing parameters determine whether projected points originating near the viewer appear brighter, while points further away are dimmed linearly with distance. The trade-off for this increased realism is that data points shown in a depth-cued image no longer possess accurate densitometric values. Two kinds of depth-cueing are available: Surface Depth-Cueing and Interior Depth-Cueing. Surface Depth-Cueing works only on nearest-point projections and the nearest-point component of other projections with opacity turned on. Interior Depth-Cueing works only on brightest-point projections. For both kinds, depth-cueing is turned off when set to zero (i.e.100% of intensity in back to 100% of intensity in front) and is on when set at 0 < n 100 (i.e.(100 − n)% of intensity in back to 100% intensity in front). Having independent depth-cueing for surface (nearest-point) and interior (brightest-point) allows for more visualization possibilities.
    2. Opacity Can be used to reveal hidden spatial relationships, especially on overlapping objects of different colors and dimensions. The (surface) Opacity parameter permits the display of weighted combinations of nearest-point projection with either of the other two methods, often giving the observer the ability to view inner structures through translucent outer surfaces. To enable this feature, set Opacity to a value greater than zero and select either Mean Value or Brightest Point projection.
    3. Interpolate Check Interpolate to generate a temporary z-scaled stack that is used to generate the projections. Z-scaling eliminates the gaps seen in projections of volumes with slice spacing greater than 1.0 pixels. This option is equivalent to using the Scale plugin from the TransformJ package to scale the stack in the z-dimension by the slice spacing (in pixels). This checkbox is ignored if the slice spacing is less than or equal to 1.0 pixels.
    4. Lower/Upper Transparency Bound Determine the transparency of structures in the volume. Projection calculations disregard points having values less than the lower threshold or greater than the upper threshold. Setting these thresholds permits making background points (those not belonging to any structure) invisible. By setting appropriate thresholds, you can strip away layers having reasonably uniform and unique intensity values and highlight (or make invisible) inner structures. Note that you can also use Image▷Adjust▷Threshold… [T]↑ to set the transparency bounds.

    1. Digital art will rival the real thing. “Will a 3D-printed sculpture have the same value as a sculpture made by someone 50 years ago with their hands? People sometimes see digital art as a lesser form of art. Oh, that is done by computer, not hand! Then people think it should be cheaper. I worry that consumers will see 3D art as something cheap — not the real thing. But once you can print a masterpiece from an artist and have it as your own, people will think differently. I am pretty sure that if Michelangelo had a computer, he would have used it.”
    2. 3D printing will continue to grow in importance. “As creatives, it’s our duty to incorporate 3D printing into our work. When you have the possibility to make your work tangible, that gives it more richness. I hope 3D printing allows people to fully customize their lives. One day if we need shoes or more silverware, we can just print them in our home. I think this will be true for all of our household basics. We’re going to have more creatives in the world because things that have traditionally been done on an industrial scale will be able to be done by anyone with 3D printing.”

    1. Unsupervised Learning of 3D Structure from Images Authors: Danilo Jimenez Rezende, S. M. Ali Eslami, Shakir Mohamed, Peter Battaglia, Max Jaderberg, Nicolas Heess (Submitted on 3 Jul 2016) Abstract: A key goal of computer vision is to recover the underlying 3D structure from 2D observations of the world. In this paper we learn strong deep generative models of 3D structures, and recover these structures from 3D and 2D images via probabilistic inference. We demonstrate high-quality samples and report log-likelihoods on several datasets, including ShapeNet [2], and establish the first benchmarks in the literature. We also show how these models and their inference networks can be trained end-to-end from 2D images. This demonstrates for the first time the feasibility of learning to infer 3D representations of the world in a purely unsupervised manner.

      The 3D representation of a 2D image is ambiguous and multi-modal. We achieve such reasoning by learning a generative model of 3D structures, and recover this structure from 2D images via probabilistic inference.

    1. Additive manufacturing

      the family of manufacturing technology that includes 3-D printing. AM is the means of creating an object by adding material to the object layer by layer. AM is the current terminology established by ASTM International (formerly the American Society for Testing and Materials) [source: Gibson, et al.]. Throughout its history, additive manufacturing in general has gone by various names: stereolithography, 3-D layering and 3-D printing. This article uses 3-D printing because it seems to be the most common term used to describe AM products.
