Destiny player builds an auto-leveling robot with Arduino


Games like Destiny can take up a lot of time if you want to level multiple characters. Or, you can let a robot do it for you.


Like with a number of video games, playing Destiny can be time consuming, particularly for those looking to level up multiple characters. And though we’ve seen several projects out there that encourage a healthier lifestyle while gaming, one Maker has done the complete opposite: designing a contraption that doesn’t require physically playing the game at all. In an attempt to create the “slowest, laziest way to level up to 20 without having to lift a finger,” Yavin Four has developed an automated mechanism using a servo motor, an Xbox controller and an Arduino Uno (ATmega328).

Destiny-Auto-Levelling

The project, which first appeared on Reddit, may not be the most complex robot, but does allow Four to open up an early Ocean of Storms level on the moon and let the game run while headed out for class, work or to grab a bite to eat. As Kotaku notes, the robot will rush enemies all by itself, reload the checkpoints and enable the character do it all over again. The Maker can then come back whenever he pleased, regain control and reap the experience rewards.

“Woke up this morning to a brand new 20,” Four wrote on Reddit. “Had about 3,600 kills, and 900 deaths, and like 50 green engrams. I started at level 16.5 yesterday afternoon, and reached 20 sometime while I was asleep. With the armor I had waiting for him he is now a 26.”

Atmel visits Beijing Makerspace… again


Beijing Makerspace is bringing tinkerers together to help make their IoT dreams a reality. 


Sander Arts, Atmel VP of Corporate Marketing, recently paid a special visit to the Beijing Makerspace on Tuesday, January 21, 2015.

Beijing Makers

There, not only did he explore the latest and greatest DIY creations, Arts participated in a well-attended press event with a number of journalists, tinkerers and entrepreneurs to discuss Atmel’s place at the heart of the rapidly growing global Maker Movement, and of course, the Internet of Things.

Located on the fourth floor of the International Digital Design Center in Zhongguancun, which has been dubbed China’s Silicon Valley, Beijing Makerspace is a community that gathers China’s Makers. The approximately 10,700-square-foot facility converges several open-source pieces of hardware such as the highly-popular AVR MCU, electronic platforms like Arduino and high-tech devices including 3D printers and robots — all the tools necessary to create next-gen IoT projects.

beijingmakerspace1

As we learned last year, Beijing Makerspace’s co-founder Justin Wang Shenglin believes that the community workshop can perhaps best be defined as a social enterprise. The establishing of the DIY hub for Wang wasn’t like starting a normal business. In fact, he tells the Chinese newspaper Global Times that it was more about finding a place where people with a common interest could come play, make and collaborate together. These people come from all walks of life — ranging from IT engineers and programmers, to designers and artists, to students and academics — and shared a common bond: making cool things!

Sander - Wang

“Having a creative idea about something is far from creating it, since craft is involved in the latter,” Wang told the Global Times in a recent interview. “Many people may start with a splendid idea, but end up finding it too hard to make it into a reality.”

As we’ve previously discussed on Bits & Pieces, Chinese government officials have also taken a keen interest in the Maker Movement in recent months due to its lucrative economic and educational potential.

“There is no other country that can perform better in craft and manufacturing than China,” explained Wang. “With an ever-growing market and firm support from the government, China is gaining its advantage in this new Industrial Revolution.”

China joins other nations, including the United States, in embracing the Maker Movement and its tremendous potential for entrepreneurship, by viewing this grassroots innovation as essential for staying competitive in our modern-day economic climate. As a May 2014 Slate article acknowledged, “The official rhetoric has a sense of urgency: China no longer wants to be seen as the ‘world’s factory,’ manufacturing goods that are designed elsewhere.”

Project

For instance, Shanghai’s municipal government has backed plans to build 100+ Makerspaces throughout the city, with each location is said to be equipped with a 3D printer and will host staff to help visitors with traditional crafts such as woodworking. Meanwhile, last year’s Maker Faire in Shenzhen attracted an estimated 30,000 people.

Wang adds, “China is a Maker’s paradise. All the materials they could want are here and extremely cheap.”

Turning plants into capacitive sensors with tinyAVR


A young Maker duo experiments with plants as a capacitive material.


Copenhagen Institute of Interaction Design students Francesca Desmarais and Paula Te recently used tinyAVR microcontrollers to turn plants into capacitive sensors.

W13-capactivePlants-1

Using an ATTiny MCU with Arduino’s Capacitive Sensing Library, the Maker duo built a circuit that could be clipped onto plants. The closer another capacitive object got to the pot, such as one’s hand, the faster the LED would blink.

“We started out clipping the circuit to non-organic sensors like aluminum foil and metal cans to discover that surface area positively correlates with sensitivity. As we continued our experiments, we learned the importance of grounding both the to earth, so that both sensors share the same ground.”

Experimenting with plants as a capacitive material allowed the students to better understand capacitance and basic electronics on the atomic level. Interested in learning more? Head over to the project’s official page here.

ButterBot is an automated buttermilk-churning machine


This littleBits contraption makes a mean glass of buttermilk.


Rather than with a cup ‘o joe, Maker Milind Sonavane kicks off every day with some freshly churned buttermilk for breakfast. As you can imagine, making buttermilk can certainly be a time consuming process, so Sonavane decided to build an automated ButterBot to simplify his morning routine.

large_filled_ButterBot021

“The Indian way of making buttermilk involves churning curd to and fro to get the fat out as butter, and leave the liquid behind as buttermilk. This is usually done with a wooden stirrer and a rope wrapped around it – tugging on either ends of the rope makes the stirrer churn the life out of the fat,” our friends at littleBits write.

The ButterBot expedites this process using an ATtiny25 powered servo motor, along with a cloudBit module to handle the time-bound automation.

large_filled_ButterBot

“We didn’t want to get into the complexities of gearing and wanted the device have an earthy feel to it. So we got two plates of wood turned on a lathe, used one as a plate for the servo motor, the other as a holder for the churner, held the two together with a piece of laser cut acrylic and connected the motion with a piece of red twine,” Sonavane explains.

large_filled_ButterBot01

How it works is super easy. Every morning at 8am, an IFTTT recipe tells the cloudBit to activate the tinyAVR based servo which moves the rope to and fro, churning the buttermilk for 20 minutes straight. The milk then sits for five minutes as the butter rises. At 8:30, when the buttermilk is ready, another IFTTT recipe turns the ButterBot off. Once completed, Makers can add milk to the bowl and leave the curd to set for the next day.

The Nerd Watch is powered by an ATtiny85


This DIY watch displays time in flashing LED binary with the push of a button.


From the looks of CES 2015, it appears that smartwatches will undoubtedly be a mainstay for the future. While a number of consumers await the Apple Watch to debut in March, Makers have decided to channel their inner DIY spirit and create a wrist-adorned timepiece of their own instead — without having to dig deep into their wallets. In recent months, we’ve seen some rather impressive designs emerge, ranging from the Arduino-compatible Tardis to the steampunk-inspired ChronodeVFD.

FSH2BDOHXLMEOQ0.MEDIUM

Added to that list is now Maker Sam DeRose’s latest binary device, aptly dubbed The Nerd Watch. Initially inspired by his dad’s Maker Faire project, the watch displays the time in hours and minutes by flashing LEDs in sequence to denote two 4-bit binary numbers. The wearable was crafted using an OMC Othermill CNC machine, and is based on a few electronic components — most notably the ATtiny85.

FOZDVLLHXLMEOV8.MEDIUM

“The [tinyAVR] has a program on it which waits for a button press, and when it senses one it grounds several of its pins so that current can flow from +3-volts through the LEDs, lighting them up. The ATtiny has an internal clock, and so the LEDs are programmed to flash to display the time,” DeRose writes.

MagnID lets you track multiple magnetic tokens


A novel way to interact with tablets and computers using magnets to be presented at Stanford University. 


A new magnetic technology will be presented this weekend at Stanford’s annual TEI Conference. Dubbed MagnID, the project is capable of tracking multiple multiple tokens at the same by tricking a tablet’s internal compass sensor.

had-magnid1

“Many tablets come with some sort of triaxial magnetic sensor but as [Andrea] and [Ian]’s demo shows, they are only capable of passing along the aggregate vector of all magnetic forces. If one had multiple magnetic objects, the sensor is not able to provide much useful information,” Hackaday notes.

A combination of both software and hardware, the team has devised custom tokens that spin magnets at precise frequencies. This creates complex sinusoidal magnetic fields that can be mathematically isolated with bandpass filters. Meanwhile, the innovative solution can also infer the distance between each token using what they call a “MagnID sensor,” which contains both an [Atmel based] Arduino and magnetometer. Therefore, the presence of multiple tokens can now be tracked simultaneously.

The demo below shows how the new tech can be used in a series of puzzles, sequential games, educational tutorials, doodling and more. While all the details have yet to be revealed, you’ll want to watch the reel below. For those interested, source code and hardware files will be made available on GitHub following the conference.

Get notified each time you’re tagged on Instagram — through scent

Created by Instructables Design Studio artist Paige Russell, the Scent-imental Notification System releases a predefined scent whenever you’re tagged by a friend on Instagram.

large_filled_SNS

The project utilizes an ATmega32U4 based Arduino module, a littleBits cloudBit, IFTTT, a few custom hashtags, and of course, scented oils. The housing for the unit is comprised of laser-cut plywood.

v02 Arduino

How it works is relatively simple. Using the littleBits cloudBit and IFTTT, as its name implies, the system notifies a user whenever a picture of them is posted on Instagram. The device is equipped with scents that are triggered by three different hashtags, which for Russell were #pupsforpaige, #cheekynature, and #snickersnort.

scent5-600x499

Each tag activates a designated servo — controlled by the ATmega32U4 module — that release a drop of oil onto a heated glass surface. The scent is then diffused up into the air and fanned towards the user by a servo fan behind the glass. The Arduino determines which servo to activate by reading an incoming voltage from the cloudBit.

A flower pot that can find its own sunlight

Tired of having your plants constantly die on you due to lack of nourishment? Wouldn’t it be nice if they were capable of tracking changes in sunlight and moving themselves? NYU ITP graduate students Xiaolong Mu and Shu Zhang are making that a reality with their tech-enabed, Atmel based flower pot aptly named Chasing Sunlight.

IMG_8542-e1418068913549-1024x1024

Four light sensors housed in a laser-cut acrylic case determine the brightest direction in the plant’s environment, along with servo motors and motorized wheels enabling the pot to get around the room. After sunset, Chasing Sunlight rolls itself back into the shade.

IMG_7730-e1418068981741-1024x1024

“We think the plants also can live like mammals or insects; it can run and have its own desires. We also have a preset for plants set in the pot, and the flower pot will give the plants appropriate sun light according to its species. The user who owns this flower pot will also get benefit from this, [as] they don’t have to worry about the the plants’s photosynthesis anymore,” Mu writes.

In the future, Mu sees his project as an easy-to-assemble DIY Arduino kit. Until then, you can watch Chasing Sunlight in action below, as well as read all about the build on its official page here.

This embedded ukulele can teach you to play chords and songs

Of course, just moments after completing our list of Maker musical masterpieces, we came across the nifty ukule-LED, an LED-embedded ukulele that uses lights to instruct how to play chords and songs.

banner

Designed by Cornell students Raghav Subramaniam and Jeff Tian, ukule-LED is equipped with 16 NeoPixels that are situated along the first four positions of the fretboard. This allows those playing the device to easily learn how to play each chord. All of the 16 LEDs are connected in series to a single pin on the ATmega1284P that sits on a board mounted to the bottom of the ukulele along with power and serial.

overview

ukule-LED has two modes of operations: “Play” and “Practice.” First, in “play” mode, the user can feed the system a song file, a text file that contains the tempo, time signature, and an ordered listing of the chords in a song. The ukulele will then light up the correct chords at the correct times in the song. (Think of it like Guitar Hero.) While in “practice” mode, the user can specify a single chord, which is lit up indefinitely. For those more experienced musicians, the ukule-LED can still serve as an excellent chord reference.

major_play

“Our inspiration for this project comes from a variety of sources. Our idea to upgrade a musical instrument using LEDs comes from various Hackaday articles, including this one. We considered using LEDs to augment a couple of other instruments, including a keyboard and a guitar, before settling on a ukulele,” Subramaniam and Tian explain.

Once mastering the earlier stages of the string instrument, those wishing to build upon their existing skills can do so thanks to ukule-LED’s extension capabilities. Currently, the system only supports major, minor and 7th chords, which light up in green, red and blue, respectively. The Makers note that the project was built using an open, highly expandable Python script available for download.

Space Weaver is a seven-foot-tall 3D weaving machine


Now that’s one heck of a Maker’s ‘dream weaver.’ 


A group of Digital Craft Lab students recently developed a seven-foot-tall 3D printer, aptly dubbed Space Weaver, that is designed to create ultra-lightweight woven structures with fibrous materials, rather than the plastics usually extruded by similar machines.

FVSESNWI3KCB32S.LARGE

Led by our friend Michael Shiloh and fellow Future Cities Lab instructor Jason Kelly Johnson, the students utilized a three-axis gantry system (similar to FDM) for creating a platform that can construct objects comprised of carbon fiber and fiberglass. With a maximum build height of five-feet, objects printed on the Space Weaver are produced using a significantly higher strength-to-weight ratio that results in no waste and requires no support material.

FTNDR3YI3KCB2WK.MEDIUM

During an eight-week build period, the young Makers approached the Space Weaver project with three different skillsets: machine building (including the frame, mechanical components, CNC gantry, electronics and spools), programming and material science. The team selected a Shapeoko 2 CNC instead of the typical 3D printer mechanisms due to its durability as well as its ability to be modified for a larger build volume.

FUSJ2BHI3KCB4YW.MEDIUM

The Space Weaver is based on a Synthetos V8 TinyG (ATxmega192), while a 24V 6.35A power supply drives all five stepper motors. Both components are enclosed in a laser-cut acrylic case for protection.
