Ultimate Waterproof Geocache Container #3DPrinting #3DThursday
cbreneman shared this project on Thingiverse!
This is a waterproof 3d printable container intended for use with geocaches, but could also be used for other purposes. It seals with o-rings and has several features to limit water ingress and keep the interior dry. Everything is customizable for making the optimal container for the application.
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
50 Words to Describe Rain in Japanese
Via FAENA aleph
Perhaps no other language can be compared to Japanese when it comes to a sensitivity to define certain aspects of reality.
In collective imagination, Nature is the original source of poetry. There it is at its purest state and, in a way, at a stage that comes before and after language, simultaneously. ––As if the phenomena that take place there were poetic in and of themselves and did not need a resource to confine their beauty because this offers itself like that: gratuitously, in the moment’s circumstance.Is it possible to know whether this is how it happens? To paraphrase a famous Buddhist koan, are the colors that arise with the first light of dawn beautiful if nobody is watching? Wittgenstein wrote: “What we cannot speak about we must pass over in silence.” He, like the Romantics, realized that there are parts of reality where language is insufficient.
And, regardless, our inclination to understand reality takes us to border on the aforementioned lands, to try and name them until we run out of expressivity. As Borges’ emblematic character, Funes, any one of us can think that the cloud that passed above just a moment ago can have the same name as that funny shaped cloud we saw yesterday. And this is justified: doesn’t the contingency of the world mean that everything is always different, that everything, in a way, is always new?
Japan Talk, a website devoted to those tiny details that can make a foreigner’s experience of the country that much better, features an article by John Spacey, where he shares 50 Japanese nouns that are used for rain ––50 different ways of describing situations that are also specific: rain falls while there is also fog; the extraordinary fact that rain can fall from cloudless skies; the first rain of summer or the rain that sneaks up on us while we’re driving.
Depending on how we see it, the number may seem either excessive or scarce. For some, the rain that falls in the evening is the same rain that has fallen since the beginning of time —and hence it can only be described by one word. Or, rain is always different, only belonging to the instant in which it irrupts in the world and therefore deserves a unique word for each occasion in which it happens.
In any case, we can attribute Japanese language with that special sensitivity for nuances and details, which is undoubtedly an essential condition required to read Nature’s poetry.

Poop, Programming, and Composting Toilets
Potty humor in the most literal sense, this composting toilet will tell you a joke. The project uses the an MP3 shield, Arduino and PIR sensor to detect use and play a practical joke. The video also makes a compelling argument for composting toilets. Shared by Summer Files on YouTube:
It’s was a rainy day so we took our adventures indoors and had a little fun with our composting toilets. If you have never seen these kind of toilets, check out our video for a great explanation of how they work and how they are different from regular toilets. We then used Arduino electronics and programming to add a practical joke to our toilets.

Homemade Roku Remote Uses Roku External Control API & HUZZAH ESP8266
This is a rad project – with thorough explanation and accompanying Github repo – by Nicolas Chourrout over on Medium.com that builds a homemade Roku remote around the HUZZAH ESP8266 breakout (and micro-lipo charger) along with some other tech, including our 4×4 matrix keypad (with remapped and stickered keys) for intentionally bulkifying the remote compared to the slender and sleek stock remote most Roku customers are accustomed to.
The Roku TV is perfect for watching Netflix but I don’t like the remote. Although the little box is small and easy to use, the infrared range is pretty bad. I almost always reach out for the iOS app instead.
The Roku External Control API offers a super simple way to control a Roku device from the local network.
For instance, once you find out the local IP address of your Roku, you can turn it on and control the volume from your terminal.
$ curl -d '' http://192.168.1.134:8060/keypress/PowerOn
$ curl -d '' http://192.168.1.134:8060/keypress/VolumeUpThis means we can build our own remote using an Arduino enabled WiFi board. No more IR issues.
This seems simple enough, let’s a build a proof of concept.
Alanna Airitam’s The Golden Age #celebratephotography
We are loving this beautiful and powerful series from Alanna Airitam. From Catherine Edelman Gallery via feature shoot:
The Golden Age is a tribute to black people. I got tired of living under the constant negative narratives and stereotypes assigned to black people and black culture and wanted to reclaim our majesty with work that showed the truth. And that truth is we are beautiful, we are powerful, and we belong. I created this body of work as a form of healing for myself. We are witnesses to the constant abuse of black lives. I decided to use my visual voice to change the messaging we receive about being black. If the media insists on depicting black people as ugly, I will show you beauty. If the government insists on a narrative that we don’t belong, I will show you how we have built this country from the ground up. If the arts cannot find room for our voices, I will build a stage and give the microphone to as many underrepresented voices that I can. We live in an increasingly volatile world. Tomorrow is not guaranteed. I’ve decided to use the rest of my life being a part of the solution in whatever way I can. And if The Golden Age has inspired or given hope to someone, then I feel I have lived a purposeful life.
See The Golden Age at Catherine Edelman Gallery through 10/27 and see more from Alanna Airitam – we highly recommend a thorough read of Alanna Airitam’s statement for this particular series.
We #celebratephotography here at Adafruit every Saturday. From photographers of all levels to projects you have made or those that inspire you to make, we’re on it! Got a tip? Well, send it in!
If you’re interested in making your own project and need some gear, we’ve got you covered. Be sure to check out our Raspberry Pi accessories and our DIY cameras.
Self Solving Rubik’s Cube
via MOTHERBOARD
Humanity conquered the Rubik’s Cube long ago, and we’ve spent the almost 40 years since its initial release in 1980 attempting to dominate it. The current world record for solving the puzzle stands at 4.22 seconds and robots can do it less than half a second. But those are external forces acting on the cube. The next level is designing a Rubik’s Cube that solves itself. That’s exactly what Human Controller, a maker from Japan, has done.

The Changing Shoreline of New York City @NYPL
Via NYPL
The Changing Shoreline of New York City surveys key points along New York City’s shoreline with a particular focus on Manhattan’s waterfront expansion. Historical maps of New York City juxtapose current coastal conditions of the city, revealing dramatic material landmass changes through time which are expressed through subtle contour differentiations mapped by a single line. The street grid of Manhattan, brought into effect by the Commissioners’ Plan of 1811, provokes a hard edged condition insensitive to the many natural ecologies and layered boundaries that Manhattan island once hosted. The plan imposes efficiency and modernity onto the diverse landscape contained in the original outline of the earliest maps of Manhattan, usually obliterating the natural conditions when confronted with a diverse shoreline.
In an attempt to destabilize the perception of coastal boundaries in Manhattan today, the stories below trace minute accounts of a Manhattan that was in the process of radical transformations. The focus on water further shifts the city imaginary to explore a territory that has been consecutively filled-in, uprooted, and neglected in the expansion of the great metropolis. This guided tour outlines existing programs along the hardened shoreline, a brief history of the site and its past shoreline qualities, as well as future proposals for many of these sites which today face variable urban pressures due to changing climate conditions and urban revitalization developments.
The Changing Shoreline of New York City is a project by Laura Blaszczak made during her internship at the New York Public Library (with some help by Bert Spaan and Luuk van de Ven), and is part of NYPL’s NYC Space/Time Directory.
To browse more maps from NYPL’s collections of digitized historical maps, prints and photos, visit Digital Collections. To plan a research visit to view maps in person or for more information about both digitized and non-digitized maps, contact the staff of the Lionel Pincus and Princess Firyal Map Division.

Cat Tracker Project Can Help You Understand Your Cat’s Personality and Secret Life
The Cat Tracker Project seeks to use data collected by citizen scientists to better understand the personalities, relationships, diets, and territorial roaming of house cats. The project has 3 ways to participate with information about your own cat by completing a personality survey, participating in GPS tracking (and viewing the results of other cat tracks), or by submitting hair for isotope analysis to examine their dietary preferences beyond the food bowl. From cattracker.org:
Your cat has a secret life…
Cats are mysterious, dangerous and far more unpredictable than one might expect from an animal that is, theoretically, domesticated. Some of the mysteries of cats relate to where they go and what they do; this is especially true of cats that go outdoors. We open our doors. They leave. Just where they go, we can’t be sure. Or rather we couldn’t be sure, until now. With your help, we’re investigating the movement of domesticated cats across the landscape. We want to know: Where do they go? What are they eating? Why do they do what they do?
Learn more about The Cat Tracker Project (and see some great images of some of the feline participants along with maps of their GPS roaming) by visiting their site here.
Toilet Tracker with Raspberry Pi and Walabot @Raspberry_Pi #PiDay #RaspberryPi
from Md. Khairul Alam via hackster.io
Have you ever found a dirty toilet especially in public place? It is very common in my place. Some people forget to flush and some don’t care if they flush. Even sometime the flush system does not work properly. An unflushed toilet is a very painful one for the next user.
So, how can you monitor this before going to use it? Using a camera can be an easy solution!!! But you can not place a camera inside a toilet.
So, what will be the next option? Yes, Walabot can be a good (may be only) alternative for this. Walabot is a programmable 3D imaging sensor that sees through objects using radio frequency technology and brings highly sophisticated sensing capabilities without taking any optical image!
Walabot senses the environment by transmitting, receiving and recording signals from multiple antennas. The broadband recordings from multiple transmit-receive antenna pairs are analyzed to reconstruct a three dimensional image of the environment.
This opens the possibility to use Walabot for 3D imaging in fields where using camera is not possible like inside bathroom or trial room or bedroom.

Whatchdog Security Robot #piday #raspberrypi @Raspberry_Pi
Via the MagPi Magazine:
Although our city streets are packed with CCTV cameras, past reports have suggested that many are either in the wrong place or simply don’t work. Perhaps the Watchdog Security Robot is the answer.
Inspired by sci-fi movies such as Short Circuit, Evolver, and Star Wars, Josh got to work on an affordable DIY robot that can trundle around the streets, operate in cold and wet weather, work well in low light, and communicate. He wanted it to record HD video locally and stream via WiFi to a secondary source for online viewing. “I decided to use a Raspberry Pi. It has an excellent community and it’s moved past being a new gadget to a useful tool.”
At first, Josh spent time getting the chassis right, using the base of a Jazzy Select power chair. He stripped away unwanted parts such as the chair, footrest, original Jazzy electronics, and the front anti-tip wheels. He also bought a Sabertooth dual 12 A motor driver which is optimised for use in medium-powered robots and radio-controlled vehicles.
Struggling to find an off-the-shelf camera that met all his needs, he turned to the Pi 3: “It meant I could pick the camera module I needed, record to a hard drive, and have remote access.” Josh used four Pi 3 boards, each connected to a camera. “In the event one fails, all the others are independent and would continue recording.”

A Look at the Making of the ‘Conn-Pod’ from Pacific Rim
Conn-Pod is one of the most interesting cockpit designs in recent sci-fi films – because of the ‘left/right’ operations of the brain but also because it provided an environment for two (or more) actors to have to co-exist and collaborate to achieve results, rather than focusing on a single actor’s presence and psychology. The video below shows some of the making of that went into the Conn-Pod, including actual mechanical and electrical (and electronic) systems designed by Legacy Effects that perform a desired function while not overburdening the actor/s physically.
Conn-Pods are typically outfitted with escape hatches that Pilots can enter or exit through once the cockpit is attached to the Jaeger; in other cases, escape hatches are located on the shoulder or elsewhere.[2] Conn-Pods are the most vulnerable part of the Jaeger. As the Kaiju adapted to the nature of the Jaegers, they began to specifically target the Conn-Pods.[2] Some Jaegers, such as Striker Eureka and Coyote Tango, are equipped with entry and exit hatches on the roof of the Conn-Pod.
Homemade RetroPie Gaming Device Modded into Wii U Pro Controller | #piday #raspberrypi @Raspberry_Pi
This slick homebrew gaming device was modded into a Wii U Pro controller by Finn Andersen. The layout of the guts inside the controller is really clever and the screen is upcycled from a car-reversing camera screen. A custom enclosure was 3D-printed using an online service and the whole thing put together looks really great!
I made a hand-held gaming console that uses a Raspberry Pi 3 and the RetroPie software suite to emulate old-school games from legacy consoles up to the Playstation 1 and Nintendo 64.
This has been one of my most challenging but also rewarding construction projects, employing a diverse range of engineering skills from power supply and audio circuitry, micro-controller programming and interfacing, CAD design, thermal management and embedded Linux. Here I’ll go through the build process and share what I learnt along the way

Networked Knitting Machine @Raspberry_Pi #PiDay #RaspberryPi
via RaspberryPi.org
Raspberry Pi: what’s there not to like? It’s powerful, compact, and oh so affordable! I used one as a portable media box attached to a pico projector for years. Setting one up as a media box is one of the most popular uses for them, but there’s so much more you can do.
Cue a 1980s Brother domestic knitting machine. Yep, you read that right. A knitting machine – to knit jumpers, hats, scarves, you name it. They don’t make domestic knitting machines any more, so a machine from the 1980s is about as modern as you can get. It comes with an onboard scanner to scan knitting patterns and a floppy drive port to back up your scans to an old floppy disk. Aah, the eighties – what a time to be alive!
But this is an article about Raspberry Pi, right? So what does a 30-year-old knitting machine have to do with that? Well, I hacked my domestic knitting machine and turned it into a network printer with the help of a Raspberry Pi. By using a floppy drive emulator written in Python and a web interface, I can send an image to the Raspberry Pi over the network, preview it in a knitting grid, and tell it to send the knitting pattern to the knitting machine via the floppy drive port.

Portable Advanced Visual Recognition Solution with Raspberry Pi @Raspberry_Pi #PiDay #RaspberryPi
from Matha Goram via hackster.io
A portable advanced visual recognition solution can help you overcome many situations where a picture is worth billions of calculations.
Open Source for Computer Vision, OpenCV, is the mother lode for image processing experiments. For hobbyists, it affords an accelerated entry computer graphics algorithms without the burden of going solo or maverick. it is therefore only natural that literature abounds with the installation and porting of the OpenCV suite on SoC boards. The Raspberry Pi is no exception. Robert Castle’s seminal work has been emulated and verified by thousands of users. Yours truly used the documentation as reference guide for the deployment on over a dozen RPi boards. This article describes one such deployment on the Raspberry Pi Zero W board.

Making Etch-a-Sketch Art With Python @Raspberry_Pi #PiDay #RaspberryPi
Awesome project + write-up from Sunny Balasubramanian.
Write a program that uses some motors to draw nice pictures on an etch-a-sketch. For the reasons above, recreating pictures by hand is tedious and extremely difficult. My hope was to get to a point where my program could draw things better than I could. I’ve always wanted to learn more about how to use hardware with python so I was pretty excited to start this one.

Installing VS Code on Raspbian #piday #raspberrypi @Raspberry_Pi
From Pi My Life Up:
In this Raspberry Pi Visual Studio Code (VS Code) tutorial I go through all the steps to installing this handy code editor.
If you’re using the Raspberry Pi as a desktop and want a decent program to edit and create code, then Visual Studio Code is perfect. It is feature packed and contains basically everything you will need to make your very own programs.
I recommend using a Git service such a self-hosted Git, GitHub or even Gitlab. These software packages are not just great for version control but also making sure that your code is backed up and readily available.
There are many other code editors that you can use on the Raspberry Pi. Each of the editors has their own pros and cons. I find VS Code one of the best that you can easily install on the Raspberry Pi.

Ynes Mexia #HispanicHeritageMonth
Born in DC as the daughter of a Mexican diplomat, Ynes subsequently lived in Texas, Philadelphia, Ontario (Canada), and Maryland before moving to Mexico City for a decade – then subsequently San Francisco, where nearby she later matriculated (at age 51!) at the University of California, Berkeley (from whom she never received a degree) before embarking on her final career path, collecting over 150,000 specimens of plants (including ~500 new species!) and gaining notoriety for being one of the most accomplished botanists of her era (which required a lot more traveling!):
Mexía began her career at the age of 55 with a 1925 trip to western Mexico under the tutelage of Roxanna Ferris, a botanist at Stanford University. Mexía fell off a cliff and was injured, halting the trip, which yielded 500 specimens, including several new species. The first species to be named after her, Mimosa mexiae, was discovered on this excursion.
Over the next 12 years, she traveled to Argentina, Chile, Mount McKinley (in 1928), Brazil (in 1929), Ecuador (in 1934), Peru and the Straits of Magellan (in 1935), and southwestern Mexico (in 1937) on seven different collecting trips, discovering one new genus, Mexianthus, and many new species among her 150,000 total samples. During her trip to Western Mexico, she collected over 33,000 samples, including 50 new species. In Ecuador, Mexía worked with the Bureau of Plant Industry and Exploration, part of Ecuador’s Department of Agriculture. There, she looked for the wax palm, cinchona, and herbs that bind to the soil. Mexía once traveled up the Amazon River to its source in the Andes mountains with a guide and three other men in a canoe. She also spent three months living with the Araguarunas, a native group in the Amazon. All of these excursions were funded by the sale of her specimens to collectors and institutions alike. Mexianthus, named for Mexía, is a genus of Asteraceae. Specimens from these trips were stored in the Gray Herbarium at Harvard University and the Field Museum of Natural History in Chicago. Mexía was remembered by her colleagues for her expertise on life in the field and her resilience in the tough conditions, as well as her impulsiveness and fractious but generous personality. They lauded her meticulous, careful work and her skills as a collector.
Via the ‘Early Women in Science‘ exhibit:
Ynes Mexia (1870-1938) was born in Washington, D.C. Her father had a child with a mistress, and her mother had 6 children from a marriage prior to meeting her father. Ynes’ mother moved her and her siblings away from their father to Texas, and Ynes had irregular periods of schooling. After she became a teenager, she lived with her father for 10 years. Ynes married a German-Spanish merchant Herman Lane in 1897. When Ynes’ father passed away, she spent a long time in court, trying to keep her inheritance from his will, which the mistress tried to take away from her. Ynes won the money and split it with two step-sisters. However, her husband died soon after this court battle in 1904. Ynes’ difficult childhood may have led to her temperamental nature, which her contemporaries often racialized and attributed to her Mexican heritage.
Ynes married a second time, at the age of 38, but divorced the man (D. Agustin Reygados). In 1920, at the age of 50, when she started to travel with the Sierra Club, and in 1921 when she became a special student at the University of California in Berkeley, she developed an interest in the natural sciences. She spent the rest of her life on various botanical collecting trips throughout the U.S., Mexico, Brazil, and Peru. She met and worked with Agnes Chase (agrostologist) and Alice Eastwood (botanist), and other famous scientists. She managed to collect thousands of plant specimens, including unknown types of plants, and she felt her life’s purpose was finally realized in helping to identify plants. She died in 1938 of lung cancer.

Ultimaker 3 door clip and stand #3DThursday #3DPrinting
Shared by Airtibi on Thingiverse:
Simple clip and stand for Ultimaker3. It can be placed with the standard screws and can be good for Extended version as well, but bigger size of plexiglass needed.
During printing the clips, it can be placed as planned, so no support needed.

Lego Micro Marble Track #3DPrinting #3DThursday
Jooxoe3i shared this project on Thingiverse!
a lego-compatible micro-marble-track construction system
designed for small ball-bearings, with a diameter less than 6mm = the track diameter.
for best results look for ones with 4.8mm diameter – the lego-stud diameter(standard 608 bearings contain some which are slightly smaller, but still in the right ballpark – got any unused fidget-spinners around?)
