This DIY meter will measure your creativity

---

Transmission is a creativity measurement system comprised of a wristband and a desktop LED display.

---

Ask any Maker or engineer, and they’ll all tell you the same thing: it’s too easy to get stuck overthinking your ideas and letting your wheels turn without making any progress on the task at hand. It’s crucial for us to get out of our own heads and sketch these concepts as they come. Although this requires plenty of practice, the more things that we jot down, the more we can create, and thus the better we can share our ideas.

Inspired by Craighton Berman’s Pencil Sharpener, SVA’s Products of Design program student Jenna Witzleben has come up with a slick way to measure creativity depending on how much you draw.

Transmission consists of two parts: a wristband that tracks your drawing and a wooden desktop display to monitor your progress. The wearable device accommodates any tool preference, whether that’s a pencil, a Sharpie market or even finger paint.

In terms of hardware, Witzleben employed an Adafruit FLORA (ATmega32U4) and an accelerometer along with a pair of XBee radios — one attached to the FLORA, another to an Arduino Uno (ATmega328) inside the tabletop tracker. The modules wirelessly communicate motion data to the creativity meter, which is embedded with NeoPixels that illuminate a series of bars based on output.

The bracelet is powered by a LiPo battery, while the LED display is driven by a 5V supply to a power jack and another supply to the Uno.

JöLLY Tracker is a shockingly awesome way to spread holiday spirit

---

This Santa-like beard uses sensors to gently zap your face as a reminder to turn that frown upside down.

---

You better watch out, you better not cry, you better not pout, the JöLLY Tracker is why. Truth be told, the holiday season can be a stressful one. Between deciding what to get loved ones to navigating your way through crowded malls, sometimes all that happiness can get lost in the hustle and bustle.

Developed by creative ad agency McKinney, the JöLLY Tracker is a wearable of a different kind. It’s not a fitness tracker. It’s not a smartwatch. It’s not even a hat. It’s an embedded Santa Claus beard that has one job, and one job only: to monitor how much you smile. Should you frown, it’ll emit a friendly little reminder in the form of an electric shock to your face. Ho, ho, how about that?

A team of creatives and hackers wanted to devise a wearable concept that would skip the normal metric tracking and go straight to helping spread some cheer.

“We wear devices on our wrists, pin them to our clothes, carry them in our pockets, each one sending us data about our well-being in hope of improving our lives,” McKinney’s ECD Peter Nicholson explains. “JöLLY is a spoof on our obsession with wearables and data. It is, simply, a joyful reminder that the holidays are the happiest time of the year.”

The setup is fairly simple, and resembles that of a recent project from our good pal Simone Giertz. A set of five electrodes are attached to the wearer’s face: two to monitor muscle movement, two to give off the shock, and most importantly, one for ground.

Hidden behind the white facial hair lies an Arduino, a Muscle SpikerShield, a battery pack and a TENS unit that gently jolts the nerves in your face. The JöLLY Tracker is controlled by an accompanying Android app that communicates with the beard over Bluetooth. It counts how many times a minute your smiling, measures the intensity of your smile and displays real-time changes in jolliness over preset intervals. If you’re too grumpy, JöLLY will send electric pulses to your cheeks and jaw. Safe to say, you’ll turn that frown upside down in no time — albeit nervously.

So in the words of Clark Griswold, just “press on and have the hap, hap, happiest Christmas since Bing Crosby tap-danced with Danny ****** Kaye.”

Build an Arduino robotic arm in a coffee tin

---

This three-axis, joypad-controlled robotic arm is tincredible!

---

If you’d like a robotic arm to help you with everyday tasks, such as picking up and putting down cylinders, but don’t have $50,000 or more lying around for an industrial model, this simple gripper might be a good place to start. Maker “AleksandarT2” constructed his three-axis robot arm (four if you count the gripper) using four hobby servos and an Arduino Uno (ATmega328), as well as glue, tape, cardboard and a coffee tin!

“This is meant to be a beginner’s guide to how to build an Arduino robotic arm. It’s concept is to be cheap and easy to build,” the Maker explains.

Given his simple materials, the device works quite well — as shown in the videos below. It’s programmed with a modified game controller, then it can repeat the movements from memory. Impressively, in the second video the arm is able to pick up and put down a cylinder twice in a row with no apparent human interaction!

Code for this gadget is provided, as well as an overview of how to modify the game controller used as a “teach pendant.” As impressive as this ‘bot is, especially given the cardboard end-of-arm tooling (EOAT), it would be a great place to start even if one intended to use better mechanical components.

KeyChainino is the first Arduino-programmable keychain game

---

Play some Pong on your keychain as you wait for the bus… or even while unlocking your front door.  

---

Remember Alessandro Matera who unveiled his Tiny Watch earlier this year? It was a simple 3D-printed LED timepiece based on an ATmega328P and powered by a 3V CR2032 battery. Well, the Italian Maker is back with yet another nifty little wearable device.

We’ve all at one time or another fiddled with our keys while anxiously waiting for the bus, train or our latte at the coffee shop. This was the inspiration behind Matera’s latest creation: KeyChainino. It’s an Arduino-programmable keychain gaming board that doesn’t require a standard mobile device to play. (In other words, it’s a great alternative for those who rather not have to whip out their smartphones.)

The Maker decided to ditch an LCD screen for an ATtiny84 powered 6×5 LED matrix and used Charlieplexing to drive the 30 tiny lights. Not only did it give it some old-school flavor, he wanted to make it easy for folks to design their own games without having to worry about how to devise boards.

One of the first games he made for it was no other than Pong. Matera shares, “I have created my first game: a simple arkanoid-like, where a ball just bouncing on the screen and you need to move the paddle – with the two buttons – to prevents the ball from falling from the playing field.”

The World’s Largest Arduino Maker Challenge is now live, and those wishing to partake in the contest can sign up/log into Hackster and enter to win the new MKR1000 board by pitching their idea.

Adding more range and LEDs to an electric longboard

---

This Maker added more battery, more range and LED underlighting to his electric longboard. 

---

Boosted boards are electric skateboards that when used by Andrew Rossignol got about seven miles of range out of the box. This worked great when he lived in New York City, but after moving to Silicon Valley, Rossignol needed more range to reach his office, now 10 miles away.

Naturally, the Maker didn’t accept this limitation and added 288Wh of high-discharge lithium-ion batteries to the 99Wh of batteries that came with the board. With this extra power, he was able to travel over 13 miles on his first ride, ending with a “fuel gauge” that still read 20%.

This would have been impressive enough, especially given his great explanation of his battery choice and wiring scheme, but he didn’t stop there. Instead, he decided to add LED lighting controlled by an Arduino Pro Mini (ATmega328) in the form of programmable strips. These were attached to the sides and front of his board.

For the color, he came up with what he calls “Boosted Orange” to match his board, also known “#FF1900” in more specific terms. For now he only has one animation programmed for the strips, but has plans to make more, and is even considering adding an inertial measurement unit. This would allow the board to sense motion and sync the lighting accordingly. That certainly sounds like an amazing effect, so hopefully he’ll be able to make that modification!

Protect your things with this picture-taking alarm

---

This Maker built a simple, Wi-Fi-enabled alarm system with Arduino. 

---

For those of you tired of your roommate using your things, colleagues taking snacks from your cubicle or classmates stealing stuff from your locker, Stefano Guglielmetti has come up with the perfect solution. That’s because the Maker has developed an Arduino-based alarm system, aptly dubbed You Can’t Touch This! 

With an Arduino Yún (ATmega32U4) at its core, the system is comprised of a PIR sensor, a camera, speakers, a microSD card and an optional USB hub. The idea is pretty straightforward: You discreetly place the device around whatever it is that you’d like to monitor. When movement is detected, the alarm will emit a siren and then proceed to take a picture and email it to you. What’s more, you can shame the thief by automatically posting their photo to friends on Facebook or Twitter via a simple IFTTT recipe.

Even better, the entire project is made up of only a handful of steps. These include configuring the Arduino, installing the camera and sound card, snapping a test pic, running an email script, building the circuit and finally uploading the Sketch to the Yún. Lucky for you, Guglielmetti has shared the entire process on MAKE:, including its code and schematics.

Let’s just say, install this alarm in your room, apartment or cubicle, and no one will take your belongings again.

This biometric band can unlock your touchscreen device

---

Instead of passwords, what if your tablet authenticated you each time you touched the screen?

---

Having to continually enter passwords isn’t so convenient, especially when you’re in a rush. With hopes of putting an end to login prompts, two researchers have developed an innovative way of authentication for pretty much any touchscreen device. The brainchild of Christian Holz and Marius Knaust (who you may recall from their earlier project Bodyprint), Bioamp is a smart strap that uses a biometric sensor and a low data rate transmitter to access and protect content on tablets.

“From each touch, the touchscreen senses the 2D input coordinates and at the same time obtains biometric features that identify the user. Our approach makes authentication during interaction transparent to the user, yet ensures secure interaction at all times,” the duo explains.

To test their concept on today’s gadgets, they first created a watch-like prototype. Bioamp is equipped with several electrodes that sense the impedance profile of a wearer’s wrist and then modulate a signal to the body through their skin. From there, the touchscreen obtains the biometric data, identifies the particular user, and continuously grants permission for each interaction.

As Hackaday notes, Bioamp’s electrodes couple a 50V 150kHz signal through a wearer’s finger to the touchscreen, which picks up both the finger’s location via capacitive sensing and the background signal that’s transmitted by the bracelet. This background signal is modulated on and off, relaying the biometric data.

“Since Bioamp senses contact with skin, it is sufficient to collect biometric values initially and then ensure that the same user is wearing the device during further use. When Bioamp detects that the user has taken off the band, it stops transmitting signals, waits for the band to be put on again, and repeats the biometric measurements for subsequent modulation,” the duo writes.

The researchers integrated their approach into a Surface 2 Pro running Windows 8.1 to demonstrate various use cases, which include payment for app store purchases, authentication for emails and notifications, as well as temporary access for sharing photos. Additionally, Bioamp supports logins that require more than one person to be present at a time. For example, two users would need to touch a single login tile simultaneously in order to unlock and open sensitive emails.

In terms of hardware, Bioamp is driven by a Blend Micro. This board features an ATmega32U4 MCU and an nRF8001 BLE chip, which handles the wireless data transmissions to the tablet to compensate for low touchscreen sampling rates. Meanwhile, power is supplied by a pair of 110mAh LiPo batteries.

While some may argue that there are limitations to the design, this idea of making touch interaction convenient and secure is pretty darn cool. You can see it in action below, and be sure to read all about it in their research paper here.

Spark up some childhood nostalgia with this DIY claw machine

---

This Arduino-based claw machine is faster, fairer and more controllable than anything in the arcade.

---

Just think how much of your parents’ money you spent as a kid playing those candy or stuffed toy-grabbing machines. You know, the ones where you put a quarter in and maneuvered a joystick in hopes of snatching a piece of junk that cost less than the amount of coins you inserted. Well, Maker Ryan Bates and the Retrobuit Games crew has developed a fairer, faster and more controllable version of the infamous claw game. The best part? It won’t require you to dig deep into your wallets.

Instead, this arcade-inspired tabletop device measures only 20” x 26” x 19” in size and is made out of aluminum extrusion and custom laser cut acrylic/wood. At the brains of the it all lies an Arduino Mega (ATmega2560) along with some NEMA 17 stepper motors.

“Everything is custom designed, from the XYZ gantry, to the claw, to the game logic. Stepper motors move the gantry, and a servo motor controls the claw (giving the claw an analog grip, not just open/close). Some parts are sourced from the plentiful DIY 3D printer market, other parts I went for cheap alternatives like replacement shower door nylon rollers,” Bates explains.

The game itself is based on a 55-second timer, which counts down on an LCD display. Simply insert a quarter (or set it to free play), and press start. Then, no different than in the arcade of yesterday, you have just under a minute to move and position the claw, grab a prize, return it to the chute and continue to reach for more. Once the clock hits zero, the claw closes, the gantry moves back to the ‘home position’ and the claw opens releasing anything it might be carrying.

Unlike the traditional arcade machines, however, this DIY model provides players with total control of the X, Y and Z axes. Horizontal and vertical movement is handled by a joystick and two buttons (up and down), respectively. Meanwhile, a knob lets users open and close the grip.

“Personally, the game is more fun since it’s based less on one-time spatial judgment and more about motor skills and planning the best route for multiple prizes,” Bates adds.

Although he began this project three years ago, the Maker has since upgraded his proof-of-concept, which includes an improved layout of the control panel (relocated the screen to the center), an increased height to allow for a gravity fed prize chute, and a ‘return to home’ function when the game ends.

He also added LEDs that illuminate the play area and offer visual cues for the game’s start and end. For instance, the lights flash when time expired” is displayed and turn off whenever the machine goes idle.

Admittedly, as awesome as the project may be, Bates still has a few things he’d like to change. He shares, “I wants to make the frame just a little bit taller (about two inches) as the coin acceptor is a big crammed, but really I am very pleased with everything! The electronics have been beefed up to handle more power if needed. I did add a secret switch on the back that can switch the power given to the z motor from 5V to 12V. This boots the lifting power from ~6oz to ~3lbs.”

This robot makes PB&J sandwiches just like mom

---

Hey bot, make me a sandwich! 

---

Ever since it made its debut at Y Combinator’s Demo Day back in August, we’ve been keeping a close eye on Bistrobot— a sandwich-making robot.

With hopes of one day expanding into more stores and dining establishments, the Bistrobot was recently installed at Andi’s Market right here in San Francisco. The automated machine crafts peanut butter sandwiches on white bread with your choice of honey, blackberry jam, sweet chili or chocolate sauce. Earlier demonstrations have even included Nutella.

“It’s already much faster than traditional methods, and we’re working to make it cleaner and more consistent,” founder and CEO Jay Reppert recently told us. “For me personally, the coolest part about Bistrobot, and why I’m working on it, is because I think robots are awesome and this is a way for more people to share in something really cool without having to spend a lot of money,”

How it works is pretty straightforward. For just $2, a customer places an order on a tablet kiosk and then watches through its transparent plexiglass enclosure as the robot creates their sandwich.

And we agree, PB&J is the most simple sandwich around, but when a robot is the chef, things get a bit more interesting. The Bistrobot team notes that it’s easy to change around the menu, making the device even more versatile and appealing to commercial users. Impressively, the robot can produce 300 sandwiches an hour — that equates to five per minute.

While Bistrobot may still be in its infancy, we definitely look forward to seeing what the future holds. Until then, you can watch it in action below! (You may also want to check out fellow Y Combinator grad TeaBOT, which as its name would imply, is an automatic tea-brewing machine.)
