This is the smartest coin jar you’ll ever use

Well, it looks like your swear jar is about to get a whole lot smarter thanks to former Cisco Systems employee Richard Rutenberg. That’s because the Maker has designed an Arduino-based, Bluetooth-enabled container that responds when fed with change.

5fc05f24a1f1afc7d1799f58cac93d07_large

A mobile app sends commands to the Coin-Jar via Bluetooth, which enables the container to display text on its built-in screen, play live music, emit prerecorded sounds, and control a series of RGB LED lights. To enhance its interaction capabilities, Rutenberg even embedded NFC technology to allow the jar to read employee badges, tokens and tags, as well as accept Apple Pay.

So, what can the Arduino Nano (ATmega328) powered Coin-Jar be used for? Rutenberg suggests accepting mobile payments for bake sales, serving as an in-office jukebox where employees scan their badges and drop a coin to play their own Pandora station, or “thanking” someone for donations through a recorded message. The Maker believes mobile wallet adoption will accelerate in the coming months, and hopes that his Coin-Jar can be a way for those who use Apple Pay and other forms of contactless payments.

According to Rutenberg, he will be releasing the files and schematics so that others can 3D print their own Coin-Jars components, and assemble them using inexpensive ATmega328 based modules. The Maker notes that he will also publish a few example programs, including a slot machine and snack bar vending program, that will help steer others in the right direction for creating their own software.

“The Coin-Jar project will release open stereo lithography (STL) files to build an inexpensive wireless connected computer that accepts US coins.    Other versions include paper money, foreign currency and near field wireless payments (cards, key fobs, etc. for iPay like merchant services), and eventually a fingerprint reader and microphone,” Rutenberg adds.

Intrigued? You can head on over to the project’s official Kickstarter page, where the Maker is currently seeking $65,000 to bring the Coin-Jar to the masses. This isn’t the first impressive fundraising container we’ve seen brought to life using an Arduino board. Earlier this year, a group of Copenhagen Institute of Interaction Design students created an interactive coin jar that not only encouraged personal savings, but also let folks contribute a part of their savings towards a good cause.

miaLinkup is bringing the IoT to your older vehicles

While today’s cars are becoming increasingly more connected than ever before, what about those dating back to 1995? Well, the miaLinkup — which recently completed a successful Kickstarter campaign — is a multi-functional wireless device that is looking to bring the Internet of Things to any 20-year-old (or younger) vehicle. 

photo-1024x768

Based on an AT45DB and an ARM Cortex-M4 MCU, the super tiny device measures just 2.4″ x 1.7″ x 1” and weighs less than 2.5 ounces. Its ultra compact size allows a user to easily plug it into their vehicle’s data port, conveniently located under the dashboard. Once paired with its companion iOS or Android app via Bluetooth, a driver can monitor their car’s battery, manage fuel costs, track trips, protect young drivers, gain remote access, use head-up display, prevent unauthorized movement, as well as locate their vehicle using the device’s built-in sensors.

“Your car and smartphone will be always connected wirelessly and seamlessly, whether your car is on or off, without any recurring yearly or monthly fees,” a company rep writes.

Fe

Apart from that, the smart gadget also comes in what team calls a “Pro Plus” version, which packs an assortment of other features like FM radio transmitter, NFC pairing, tire pressure monitoring systm, MEMS digital microphone, a speaker, microSD card slot for up to 32GB, as well as support for both Ford Medium Speed and Single Wire CAN.

7968e2b9f7726c009efca749666c7405_large

In addition, miaLinkup’s open API — aptly dubbed miaAPI — enables developers to create more apps that can interact with a vehicle via the miaLinkup device using the Atmel powered ECUemu3000 tool.

So, whether you’re having a Dude, Where’s My Car? moment and cannot locate your parked car, or would like to keep a Ferris Bueller’s Day Off valet incident from happening, the miaLinkup is the answer. Learn more by heading over to the project’s official page, where the team more than tripled its original $50,000 goal.

This DIY device is putting the ‘Matrix’ in matrix clock

While we’ve seen our fair share of DIY LED clocks in recent months, none may be as unique as Dan Hamer’s latest project which literally puts the ‘Matrix’ in matrix clock. Unlike the others, time is replaced in a Matrix digital rain-like animation, which trickles from above. Originally spotted by our friends at Hackaday, the project is best described as an incredibly compact, Arduino-powered clock with 16 x 8 LED display.

matrixclockmain

Based on the Arduino Leonardo (ATmega32U4), the Matrix Clock is fully compatible with the Arduino IDE and can be easily updated or customized with new sketches via its built-in USB connectivity. Meanwhile, a coin cell powered real-time clock calendar keeps track of the time and date when the unit is not powered.

7187411419699941859

Not only is the device equipped with three different animated transitions and clock displays, the Matrix Clock can also play personalized musical alarms that can be easily reprogrammed with new tunes. Given its small form factor, the gadget can be fitted into any number of housings,many of which can be 3D-printed.

Brewing up a coffeemaker payment system with ATmega328

Maker Oliver Krohn — who you may remember from his recent Juraduino device — has now modded an off-the-shelf Jura Impressa S95 coffeemaker to include an AVR powered RFID payment system.

Coffee

The system is driven by an ATmega328 based board, an RFID reader, a Bluetooth module along with a few other components, all enclosed in a plastic case. The board communicates with the coffeemaker using its service (serial) port, which means you won’t risk voiding the machine’s warranty.

Clip

How it works is relatively simple: A user taps his or her contactless identification card over the RFID reader, which reveals the account balance. If enough credits remain, the coffeemaker will pour a hot cup ‘o joe.

CoffeeMaker

The Arduino-like board connects to an Android smartphone via the machine’s embedded Bluetooth module. The companion application, which was devised using MIT’s app inventor, allows the coffeemaker owner to register and maintain up to 40 users, charge or delete accounts, keep track of credits, as well as update the coffee pricing list.

Video: Tap yourself awake in the morning with the DrumAlarm

We’ve all done it: Your alarm clock sounds, you unconsciously turn it off and suddenly wake up several hours later. Thanks to Maker Tarek Khamis, that’ll never happen again. The DrumAlarm is an Arduino-based device that ensures your attention has indeed been stimulated and you’re alert enough to start your day. No snooze button on this gizmo! In order to switch the DrumAlarm off, a user must play back a programmed set of drum licks correctly. While it may sound easy, it’s not… especially in the wee hours of the morning. The DIY gadget not only detects the predefined drumming pattern, it also measures timing and accuracy. In other words, you’ll need to be annoyingly precise!

Sort through M&M’s in speed with this iPhone-controlled machine

While we’ve seen plenty of candy-sorting machines in recent months, an anonymous reviewmylife blogger has devised a pretty sweet creation that’ll have you sifting through treats faster than ever before. Not only for the everyday chocolate lover, this contraption can be quite useful for concert venues looking to book Van Halen or Mariah Carey, whose rider requests demand no brown and yellow M&M’s, respectively, in their backstage candy bowls.

mandm-sorting-machine-front-12

The Maker claims that the DIY device is faster than most other sorters, which works by registering the candy’s’ color using an iPhone 5 camera. The high-speed M&M machine is equipped with a 12V 80RPM high torque motor that controls a rotating plate, before releasing one candy at a time through a hole.

mandm-sorting-machine-dispenser-10

As the M&M falls, the iPhone deciphers its color and communicates via Bluetooth to an Arduino Mega (ATmega1280). The Arduino then uses an eight-channel relay to fire off electromagnet-controlled gates that send the candy piece down a chute and into the appropriate bin.

mandm-sorting-machine-side-arduino-bluetooth

Although much quicker than other DIY M&M sorting projects, the blogger notes that there is still plenty of work to do. As good as the iPhone’s color sensing capabilities may be, the device still has trouble deciphering brown candies. “They are a pain to distinguish from orange and shadow. Obviously it can be done but it would need a bit more software work and perhaps some LED lighting on the chute to reduce the effect of the shadows,” he added. The Maker also says that he’d like to get the parts for the machine 3D-printed in the near future.

Pretty sweet, right? See it in action below!

This DIY trainer is like a Whack-a-Mole for boxers

Back in the 1985 classic Rocky IV, Balboa’s rival Ivan Drago was shown utilizing a futuristic electronic punch meter in his quest for triumph. Inspired by the flick, a group of Cornell students recently designed their own electronic boxing trainer system for beginners and well-seasoned athletes alike. The device is capable of teaching both basic and advanced combinations, while also providing users with a gauge of timing and accuracy.

intro1

“While we desired to have ‘built-in’ sequences to train the user, we also desired to allow the user to self-program and store their own practice combination sequences. We attempted to do this without exceeding a budget of $100,” the team writes.

The project is comprised of five square pads organized in the shape of a human head and upper body, with each square surrounded by bright LED ribbons that emit light based on a pre-conifgured pattern. Think of the system as a life-size Simon or Whack-A-Mole: When a pad lights up, the trainee must hit it. If the user fails to strike the pad within a set deadline, the next punch in the sequence proceeds. The game, which is controlled by an ATmega1284P, keeps tabs of the user’s activity in terms of reaction, accuracy and other relevant statistics.

In an effort to keep costs at a minimum, the students created their own force sensors consisting of two square pieces of fine aluminum windscreen with foam structures placed in between. One of the foam pieces was made from conducting ESD foam, while the other was a piece of half-inch thick insulating foam rubber with quarter-inch slits cut approximately half an inch apart, for approximately 12 slits per sensor.

force1

“In each of the screen pieces, we thread (copper) wire through the (aluminum) screen’s holes in a ‘Z’ pattern and bond the metals together with conducting glue. The jailbar foam is then hot-glued to the ESD foam, and then the composite foam is sandwiched via hot glue between two of the wire-threaded screens. The screens are then covered on their exposed sides with cardboard that has been rolled with a wine bottle to reduce its brittleness (by popping any trapped air pockets). We used four 10” by 10” sensors to create the ‘body’ of a figure, and a 9” by 9” sensor for the head.”

The sensors are then mounted against a wall, or in the Cornell project’s case, a back of a metal exterior door. When a user punches a sensor, it compresses and as a result, causes the resistance between the two pieces of aluminum screen to change. This greater the change in resistance, the more powerful the hit.

Meanwhile, feedback to the user and the programming interface is done by serial communication. The team interfaced with a PC using a USB-RS232 cable and PuTTY.  The code for the system can be divided into three distinct categories: initialization, user input via PuTTY (or other serial terminal) and game play.

Interested in learning more about the project as well as the team’s outcome? You can read the entire log of their build here, or watch a demo of the boxing trainer below.
