8-bit Frogger game on a digital microfluidics device

OpenDrop V2 is an updated design for an open-source digital microfludics platform, which was initiated by GaudiLabs in Luzern, Switzerland and developed in collaboration with several communities including hackteria | open source biological art, BioFlux and digi.bio. The device is part of a much larger ecosystem focused around digital biology with hopes of making personal lab automation accessible to everyone. OpenDrop runs on […]

Save pangolins

Pangolins now are facing critical crisis as they are closing to extinct. In fact, humans are the murderers of this disaster, superstition and greed are the main reason to cause this massacre.
Pangolins, the mammals covered in tough and overlapping scales, are actually far from aggressive. Their scales provide good defense against predators in wild. However, they’re considered the world’s most hunted animal because people believe that the meat is prized for medicinal ingredient and the scales help curl impotence.
Nowadays, the numbers of pangolins are less and less, some people eat them only for the reason of showing their ostentatious wealth, what they do to these helpless animals is to make them approach to endangered. Although International trade in pangolins has been banned by CITES since 2000; and are listed them as ‘protected species’ in most Asian home states, scaly anteaters are still threaten with smuggling and poaching. Pangolins’ disappear would not be the result we expect to see, only when strictly implement of law enforcement on punishing these poachers and pangolin-eaters would effectively bring down the crisis of extinction. This is our latest chance to save pangolins, and please never make science predictions come true.

Pangolin is a really skillful and difficult work that I have spent a lot of time on it. It has been passed at least six editions before presenting to all of you. What I was trying to challenge is an artwork with both perfect appearance and function. It was a little struggle for me to share this work at the beginning since I’ve fallen in love with it when it’s first done and stood in front of me. At this moment, what I am wondering more is to let you firsthand it, holding and feeling the variation with actions. Enjoy and I believe you’ll like it.

Same file will be uploaded to http://fastlab.tw/, (Institute for Information Industry, III), which is a 3D works sharing website, welcome all 3D players upload your works and have fun here!

穿山甲正面臨迫切的危機,牠們走在快速滅絕道路上,人類是這場災難的兇手,迷信與貪婪是屠殺的原因。

穿山甲這個性情溫和的動物,全身佈滿鱗片,這些鱗片在野外對於保護自己有些幫助,但是身上的鱗片也是牠們被獵殺的因素。因迷信穿山甲的鱗片有醫療與壯陽的效用,導致穿山甲這無辜的動物被瘋狂獵殺。也因為野外的穿山甲越來越少,所以穿山甲成了昂貴的食物,有些人僅僅是為了炫富而食用穿山甲,這樣的行為也把穿山甲推上最後的滅絕之路。雖然現在穿山甲在多個國家及地區均禁止出口及貿易,但是走私與盜獵依然存在!落實執法,逮捕並懲處這些盜獵者及食用者才能真正解決穿山甲的危機。科學家認為亞洲的穿山甲可能將於20年內滅絕!這不是我們想要的結果,現在就是解救穿山甲的最後機會。請別讓科學家的預言成真。

這個作品我花了很多的時間,是一個難度很高的作品,自開始到完成創作至少修改了6個版本,不停地推翻與重建,因為我在挑戰一個美與機能都要兼具的作品。所以當我完成這個作品時,也同時愛上這個作品,因此有些捨不得分享出來。但我更期望朋友們也能夠親自體驗我的感受,能將牠握在手中,感覺牠的觸感、聲音與各種動態的變化。當你下載了並列印這作品時,願你也能像我一樣愛上這個作品。

同樣的檔案我也分享於 http://fastlab.tw/ 這是台灣資訊策進會的3D分享網頁,希望各位3D玩家也能慢慢豐富這個地方。

Yet ANOTHER Machine Vise

This is a quite robust 3d-printable machine vise. It’s 100% 3d-printed – no screw or other piece of hardware is needed to hold the individual pieces together. Pieces clip and snap together.

It’s a demonstration that it is very important to consider forces and material properties already when designing a mechanical object. Hints about proper design are presented in my video:

https://youtu.be/mziT7KV-fRI

The video also includes explanations how to assemble this vise.

For 3d-printing it’s recommended to print 3 shell layers. 35% infill is sufficient. All the forces for clamping a workpiece are only active at the outer surface – more infill doesn’t make the vise more robust. Layer height is 0.15 mm (maybe screws are better printed with 0.1mm layers). No support material needed. Printed with 0.4 mm nozzle.

Assembly: https://jig.space/view?jig=1216 (thanks to http://www.thingiverse.com/greenlig)
Designed with Fusion 360: http://a360.co/2juhSUG

If there are difficulties to print the threaded rods vertically, I’ve designed a version of the sliding jaw with horizontally printed rods: http://www.thingiverse.com/thing:2123529

An experimental game with a conductive rubber band controller

RubberArms is an experimental rubber band game, created by Robin Baumgarten at the Global Game Jam 2017 in Yverdon-les-Bains, Switzerland. The controller uses a conductive rubber cord from Adafruit that changes resistance as it’s stretched. This resistance is measured by an Arduino Micro/Leonardo (or a Teensy 3.2), which acts as a USB joystick sending signals to Unity3D. (The game is coded […]

Make your reflex punching bag interactive with Arduino

A traditional reflex bag is meant to help improve your punch accuracy and timing. However, Carl Gordon decided to make his a bit more interactive and gamified using an Arduino Uno. As you can see in the video below, his setup adds four LEDs to the device to tell the user which side of the bag to punch, […]

IR thermometer hacked into an IR camera

Using several clever hacking techniques, Niklas Roy can make thermal images using a “simple” thermometer. True IR (infrared) cameras are still too expensive for many of us, but if you’d just like to know the temperature of something at a distance, IR thermometers aren’t that costly. In theory, if you were to take readings in […]

Hidden Figures – Friendship 7

Portraits of NASA mathematicians Dorothy Vaughan, Mary Jackson and Katherine Johnson in bas relief on the Friendship 7 capsule. The story of these African-American women’s pivotal role in the first orbit of the Earth by an American is told in the book and movie Hidden Figures.

The model is easily recognizable as a space capsule but only when it is lit from inside do these ‘hidden figures’ fully reveal themselves. This model symbolizes the invisible but vital contribution African-American women made to the early space program.
There are three version of this model.
v1 One piece model of Friendship 7 with portraits in bas relief on exterior.
v2 Two piece model of Friendship 7 with portraits in bas relief on exterior.
v3 Two piece model of Friendship 7 with portraits engraved from interior.

The appearance of the portraits with backlight (lithophane) depends on a variety of factors including scale factor, slicing settings, filament opacity and light source. Experimentation and test prints are required. These models are suitable for remixing for a variety of projects. Example photos are from model scaled at 60% for use as a nightlight.

Bookcase automatically opens to reveal secret lair

A secret lair isn’t much fun if it’s a pain to get into, so Instructables user SPECTREcat decided to automate his hidden doors using an Arduino Uno. This drives four linear actuators via a MultiMoto shield, which both pull and turn the bookshelf in such a way that the books stay in place. When opening, […]

Headphone Stand

The MakerBot Headphone Stand went through the same design process used in professional design and engineering industries. Multiple design iterations and 3D prints led to the final fully 3D printable headphone stand.

The full size stand prints beautifully without any supports and perfectly matches the Replicator+ build volume.

Designer Jackson Seidenberg uses two of these stands at home for his Logitech G930 and Astro a50 headphones.

Ep. 123 – Rails Girls Summer of Code (Laura Gaetano)

Before becoming a developer, Laura had a number of job titles, including music blogger, DJ, and maid. But it was a Rails Girls workshop that brought her back to the world of web that she fell in love with many years ago. Now, as a manger at the Travis Foundation, she gets to help introduce other women to tech through the Rails Girls Summer of Code, one of the many initiatives she runs. She tells us more about what it’s like to be a scholar in the program, the power of doing meaningful work on open source projects, and how she reconnected with the web and became a developer.

Ep. 122 – The Ethics of Coding (Bill Sourour)

Bill Sourour was twenty-one when he was asked to build a website for a pharmaceutical company. It was a quiz that asked users to select symptoms so that it could recommend a drug as a possible solution. But for almost every option the user selected, the quiz would recommend the same drug. It didn’t feel right, but when Bill later heard that a side effect of the drug was depression and a young woman who had taken that drug had committed suicide, it felt very, very wrong. Bill tells us the story of his first code-related ethical conflict, his thoughts on the ethical responsibility of coders, and how the incident affects how he approaches code today.
