A Simple Floppy Music Controller
http://hackaday.com/2014/10/12/a-simple-floppy-music-controller/
While playing music with floppy drives has been done many times over, making any device with a stepper motor play music still appeals to the hacker in all of us. [Tyler] designed an Arduino shield and a library which lets you get up and running in no time. [Tyler]‘s shield includes pin headers to connect 4 floppy drives, which plug directly into the shield. The drives don’t need any modification before being used.
While you could simply wire a few floppy drives up to an Arduino with some jumpers, this breakout shield makes connecting your drives trivial.

Heistmeisters crack cost of safecrackers with $150 widget
Arduino hack-box brute-forces ATMs, gun safes
http://www.theregister.co.uk/2014/10/13/heistmeisters_crack_cost_of_safecrackers_with_150_widget/
A pair of Melbourne security professionals have developed a $150 auto-dialer safe cracker that replicates a machine worth tens of thousands of dollars and sold only to military customers.
The unit launches automatic brute force attacks against group two combination locks used in high-security environments like ATMs and gun safes.
Current and former penetration testers Luke Janke and Jay Davis created the device using Arduino and 3D printed components.
“They pretty much use group two locks for everything,” Davis said at the Ruxcon security conference in Melbourne.
“A lot of these locks have about 10 default combinations which never ever get changed and they would be the ones you would want to try out first.”

New Brain for an Old Washing Machine
http://hackaday.com/2014/10/14/new-brain-for-an-old-washing-machine/
When the washing machine at [hydronucleus]‘s place went on the fritz, he went straight to the toolbox to try to repair it. The problem was with the old mechanical control unit, so [hydronucleus] got an Arduino out of the parts bin to create a brand new electronic controller for his washing machine.
Arduino Based Washer Controller
http://imgur.com/a/9L0LI
So overall, it cost me about $54 over the Arduino UNO ($35) that I already had. I consider this total of $89 expensive, but it still substantially less than $200 for a new mechanical controller. Now in reality when you figure in what my salary should be as PhD in Computer Science (if I were employed) and the amount of time I put into it, it was probably about a $3000 repair for a washer that originally cost $75.

Margarita Drip Infuser Ensures a Perfect Mix
http://hackaday.com/2014/10/14/margarita-drip-infuser-ensures-a-perfect-mix/
n order to get a margarita just right, the various ingredients need to be mixed together quite vigorously to over-come the different viscosity of the fluids. Looking to create his own barbot of sorts, [TVMiller] decided to make a Margarita Drip Infuser to help make margaritas a bit easier.
Using various chem lab supplies, [TVMiller] has cobbled together something pretty awesome. The Infuser can take up to 8 different ingredients into its test tube reserves, and after the drink ingredients are programmed on the computer, the magic begins.
Margarita Drip Infuser
Drop by drop to a smoother cocktail
http://hackaday.io/project/3167-margarita-drip-infuser
A semi-traditional Margarita pour requires vigorous agitation in an attempt to blend the varying viscosity fluids constructing the cocktail. As an alternative, less abusive and theoretically smoother method, we affixed an Arduino Uno to an 8 channel relay controlling 8 solenoids to drip each ingredient, of any varying recipe, one drop at a time; allowing the blend to occur in real time. The glass is held in a copper wound that a coolant fluid is pumped through. Forgive the impoverished components, both mechanical and delicious.

A Single Pixel, Color Digital Camera
http://hackaday.com/2014/10/20/a-single-pixel-color-digital-camera/
[Ben] wanted a digital camera. Not any digital camera, but a color digital camera, and didn’t want to deal with pixel arrays or lenses. Impossible, you say? Not when you have a bunch of integral transforms in your tool belt.
[Ben] is only using a single light sensor that outputs RGB values for his camera – no lenses are found anywhere. If, however, you scan a scene multiple times with this sensor, each time blocking a portion of the sensor’s field of view, you could reconstruct a rudimentary, low-resolution image from just a single light sensor.
[Ben]‘s camera consists of the Adafruit RGB light sensor, an Arduino, a microSD card, a few servos, and a bunch of printed parts. The servos are used to scan and rotate the ‘blocking arm’ across the sensor for each image.

Battery Shield Mounts Underneath The Arduino
http://hackaday.com/2014/11/06/battery-shield-mounts-underneath-the-arduino/
So, what do you do when your Arduino project needs to operate in a remote area or as a portable device? There are LiPo battery shields available, and although they may work well, recharging requires access to a USB port. You can also go the 9v battery route plugged into the on-board regulator of the Arduino but the low mAh rating of a 9v won’t allow your project to stay running for very long. [AI] needed a quick-change battery option for his Arduino project and came up with what he is calling the AA Undershield.

What doesn’t this Arduino Mega shield have? Ponder that as you realize that it doesn’t just attach itself to the pin headers, but uses every single one of the mega’s connections.
This isn’t a bunch of components kludged together either. [Carsten] is an a EE and that explains a lot of the really great choices he made like buffering, opto-isolation, and the clean assembly despite a schematic that’s so busy it’s difficult figure out where to start.
So, what does it do? Looks like a one-stop-shop for quick prototyping needs.

Sci-fi grade Home Automation
A system that ties some home automation with various APIs and hardware hacks.
http://hackaday.io/project/456-sci-fi-grade-home-automation
The goal of the sci-fi grade home automation system is to address a couple things I don’t like existing systems:
Commercial systems tend to focus on three things: lights, cameras and thermostats. There’s nothing wrong with that, but it is a very small scope compared to what modern technology can do. I usually don’t need to see a real-time video of my apartment wall, and outlet switches are only moderately convenient, not life-changing.
I decided to make something inspired by Corning’s “A Day made of Glass” videos. That system focused on displaying interesting information, and it was awesome. Existing systems don’t do that, for reasons I don’t really understand.

Powering Your F-16 With An Arduino
http://hackaday.com/2014/11/14/powering-your-f-16-with-an-arduino/
[Craig]‘s friend was working on getting an F-16 restored for the Nuclear Museum, and like anyone with sufficient curiosity, asked how hard it would be to get the navigation lights working again. [Craig] figured an Arduino would do the trick, and with the addition of a shield loaded up with a few mosfets, the nav lights on an old F-16 would come to life once again.
Arduino Powers F-16
http://www.spudcentral.com/potd/141114.html
A friend of mine from Albuquerque called on September 3rd and said he was helping the Atomic Museum renovate an Air Force F-16 and asked, “How hard would it be to get the lights working again?” I thought for a couple seconds, “Not hard at all, I can just wire up an Arduino with some MOSFETs and ship it to you.” “But there’s no power at the plane.” “No problem, just run the lights off a car battery and charge it with a solar panel.” “Sounds simple enough.” So we got started.
I found all the parts for a protoshield, then decided I should just make a custom shield for this project. Later that evening, after walking my dogs, the Lucky7 board was designed, schematic entered, layout completed and board files sent to iTead PCB.

[Greg] implemented a simple ray tracer for Arduino as a fun exercise and a way to benchmark the processor. He started out with the Moller-Trumbore algorithm, a common ray-tracing algorithm that calculates the intersection of a ray with a triangular plane without doing any pre-calculation of the planes. His code supports one static light and one static camera, which is enough to render a simple scene.

Moti is a smart servo motor that makes it easier to build robots.
Moti makes it easier to build such systems by providing requisite features within the motor. There’s a programmable microcontroller, breakout pins for attaching sensors, daisychain networking, and a continous rotation servo, with 360º position sensing inside each Moti. It eliminates the need for external circuitry.
We also want Moti to play well with the web and mobile devices, so there’s a RESTful API for developing apps. And we’ve built the first one that gives you immediate control of your Moti-enabled robot.

Unless you live off-the-grid and have abundant free electricity, leaving your rig on while you go away on trips is hardly economic. So if you’re like [Josh Forwood] and you happen to use a remote desktop client all the time while on the road, you might be interested in this little hack he threw together. It’s a remote Power-On-PC from anywhere device.
It’s actually incredibly simple. Just one Arduino. He’s piggybacking off of the excellent Teleduino software by [Nathan] who actually gave him a hand manipulating it for his purpose. The Arduino runs as a low-power server which allows [Josh] to access it via a secure website login. From there, he can send a WOL packet to his various computers to wake them up.

Teleduino converts your ethernet enabled Arduino into a powerful and versatile tool for interacting with devices over the internet.
https://www.teleduino.org/
Once your Teleduino is configured, it automatically connects itself to the Teleduino server when powered on. The Teleduino server translates instructions received from the internet into actions on the Teleduino device.
Using the Teleduino platform, you can perform the following tasks with your Arduino via the simple web service:
Reset, ping, get uptime, get free memory.
Define pin modes, set digital outputs, set analog outputs, read digital inputs, read analog inputs, or read all inputs with a single API call.
Define, and read and write from serial port (4 for the Mega).
Read and write from EEPROM.
Define and position up to 6 servos (48 for the Mega).
Interface with I2C (TWI) sensors and devices.
While there are options available to make API calls over a secure connection using SSL, the data between the Teleduino Proxy Servers and a Teleduino device remains un-encrypted. This is due to limitations of the Arduino Ethernet device. Teleduino takes no responsibility for any interception of data.

Arduino Controlled Sewing Machine Increases Stitch Options

[Andrew] is bringing his old mechanical sewing machine into the 21st century by adding an Arduino control module. Originally, his Alfa sewing machine could only do a straight stitch or a zig-zag of varying widths. Since this was an old sewing machine, all of the controls were knobs and levers. RC car servos were installed in the sewing machine and now are solely responsible for controlling, in real time, the horizontal movement of the needle and the amount of stroke of the feed dogs (the metal components responsible for advancing the fabric through the sewing machine). There is also a switch on the needle bar that feeds back to the Arduino when the needle is in the full-up position.

Have you ever wanted to connect your Arduino to sensors or other devices but over a long distance? And we don’t mean a few metres – instead, distances of up to 100 metres? Doing so is possible with the CATkit system from SMART greenhouse.
This system is a combination of small boards that are connected between your Arduino and external devices using CAT5 networking cable, giving a very simple method of connecting devices over distances you previously thought may not have been possible – or have used costly wireless modules in the past.
The maximum distances possible depend on the signal type, for example:
analogue signals up to 100 metres (with a 0.125 V drop)
1-wire signals (ideal for DS18B20 temperature sensors) up to 75 metres
SPI bus up to 50 metres
I2C bus up to 35 metres
Serial data at 9600 bps varies between 50 and 100 metres

Using RC Transmitters With Flight Simulators
http://hackaday.com/2015/01/26/using-rc-transmitters-with-flight-simulators/
It’s winter, and that means terrible weather and very few days where flying RC planes and helicopters is tolerable. [sjtrny] has been spending the season with RC flight simulators for some practice time.
The usual way of using an RC transmitter with a computer is to buy a USB simulator adapter that emulates a USB game pad through a port on the transmitter. Buying one of these adapters would mean a week of waiting for shipping, so [sjtrny] did the logical thing and made his own.
After connecting the rudder, elevator, aileron, and throttle signals on the receiver to an Arduino, a simple bit of code and the UnoJoy library allows any Arduino and RC receiver to become a USB joystick.

Arduino openHAB Garage Door Control
Make a smart garage door opener using an Arduino and OpenHAB
http://hackaday.io/project/4027-arduino-openhab-garage-door-control
openHAB is a great platform for interfacing with Internet of Things stuff. This project explores using openHAB and an Arduino Yun to activate a garage door opener, monitor the door’s open/closed status and measure temperature.
Let’s build a garage door controller that can make intelligent decisions. And actually open the door when I want it to.
With an Arduino and openHAB, we can build a system that will allow for monitoring and control of the door from a webpage or mobile device. The main elements look like this:
openHAB
http://www.openhab.org/
Welcome to openHAB – a vendor and technology agnostic open source automation software for your home.
Build your smart home in no time!
What is openHAB?
openHAB is a software for integrating different home automation systems and technologies into one single solution that allows over-arching automation rules and that offers uniform user interfaces.
This means openHAB
is designed to be absolutely vendor-neutral as well as hardware/protocol-agnostic
can run on any device that is capable of running a JVM (Linux, Mac, Windows)
lets you integrate an abundance of different home automation technologies into one
has a powerful rule engine to fulfill all your automation needs
comes with different web-based UIs as well as native UIs for iOS and Android
is fully open source
is maintained by a passionate and growing community
is easily extensible to integrate with new systems and devices
provides APIs for being integrated in other systems
openHAB does not try to replace existing solutions, but rather wants to enhance them – it can thus be considered as a system of systems.
The openHAB comes with a demo package which have all the configuration to play with a model of a house with some rooms, lights, heating and all the stuff.
Every technology or device, social network or cloud platform integrated into openHAB is supported by a specific bundle. Those bundles are optional and pluggable, they can be added to your openHAB as soon as you need them.
Bindings provide integration with different home automation technologies and devices while there are quite a lot of other bundles providing integration and communication with social networks, instant messaging, cloud IoT platfroms and much more.

Automated Tea Maker
http://hackaday.com/2015/01/28/automated-tea-maker/
[Pariprohus] wanted to make an interesting gift for his girlfriend. Knowing how daunting it can be to make your own tea, he decided to build a little robot to help out. His automated tea maker is quite simple, but effective.
The device runs off of an Arduino Nano. The Nano is hooked up to a servo, a piezo speaker, an LED, and a switch.
the bag is lowered into the hot water and held for approximately five minutes. Each minute the bag is raised and lowered to stir the water around.
Once the cycle completes, the Nano plays a musical tune from the piezo speaker to remind you to drink your freshly made tea.

Keystroke Sniffer Hides as a Wall Wart, is Scary
http://hackaday.com/2015/01/14/keystroke-sniffer-hides-as-a-wall-wart-is-scary/
The latest is a device from [Samy] that is able to log the keystrokes from Microsoft keyboards by sniffing and decrypting the RF signals used in the keyboard’s wireless protocol. Oh, and the entire device is camouflaged as a USB wall wart-style power adapter.
The device is made possible by an Arduino or Teensy hooked up to an NRF24L01+ 2.4GHz RF chip that does the sniffing.

DIY Oscilloscope using Arduino and Graphic LCD (Osciduino)
https://www.youtube.com/watch?v=tOTx_lSTZNA
I have designed an Oscilloscope using Arduino Mega 2560 and 128×64 GLCD. It works pretty good for verification of signal the range of input frequency is upto 10-12MHz and Sampling rate is 200KSPS.
All the Arduino GLCD libraries used are freely available.

I don’t claim that this device can replace actual test equipment but it might be useful and for $40.00 bucks in total parts it is a blast to play with.
Bottom line, it is definitely fun to build and play with

Serial Oscilloscope (with Arduino)
https://www.youtube.com/watch?v=jgMG0UQ2_pc
Serial Oscilloscope plots comma-separated variables within any incoming serial data stream as channels on a real-time oscilloscope.
In this video I show it being used with an Arduino to plot data from an IR range sensor, triple axis accelerometer and microphone.
Serial oscilloscope
http://www.x-io.co.uk/serial-oscilloscope/
Serial Oscilloscope is a Windows application that plots comma-separated variables within any incoming serial steam as channels on a real-time oscilloscope. The application also functions as a basic serial terminal, received bytes are printed to the terminal and typed characters are transmitted.
Serial Oscilloscope is compatible with any serial stream containing comma-separated values terminated by a new-line character (“\r”). For example, “11,22,33\r” will be interpreted as values 11, 22 and 33 for channels 1, 2 and 3 respectively. The serial stream can also include non numerical characters which will be ignored.

Arduino – Multi-Channel Oscilloscope (Poor Man’s Oscilloscope)
http://www.instructables.com/id/Arduino-Multi-Channel-Oscilloscope-Poor-Mans-O/
Note that this “device” is not an actual oscilloscope. Most of the features you’d expect from an oscilloscope are not available. However, if you like to visualize data that is not too fast, then this is simply awesome.
Download Processing. Processing is a programming environment that looks and feels identical to the Arduino programming environment. It also comes at the same price, which means it’s free.
Depending on how many channels you like to have, upload one of the “Arduino sketches” shown below into your Arduino.

A Tweeting Vending Machine
http://hackaday.com/2015/02/10/a-tweeting-vending-machine/
[Sigurd] manage to obtain an old vending machine from his dorm. The only problem was that the micocontroller on the main board was broken. He and his friend decided they could most likely get the machine back into working order, but they also knew they could probably give it a few upgrades.
This system uses two Arduino Pro Minis and an Electric Imp to cram in all of the new features.
IOT Arduino Vending Machine
http://blog.tkjelectronics.dk/2015/02/iot-arduino-vending-machine/
In this blog post I will describe a IOT (Internet Of Things) Vending Machine that I built quite some time ago with a friend of mine Sigurd Jervelund Hansen.
One Arduino Pro Mini is connected to the mainboard and takes care of reading and lighting up the buttons (lights up if the relevant slot is not empty), controls the 7-segment LED display, reading the output from the coin validator and returning money if the user requests it by pressing a dedicated button.
A second Arduino Pro Mini is used to read NFC/RFID cards using a Mifare RC522 reader.
On top of that we also made it able to tweet. First we used a Raspberry Pi connected to the Arduino via Bluetooth, but as the SD card on the Raspberry Pi kept getting corrupt, we ended up using an Electric Imp instead. It is a 32-bit ARM Cortex M3 microcontroller with a WiFi module built into a SD card form-factor.
The Arduino will send out a status update every minute, the Electric Imp will then send out a tweet if there is any updates.

Converting Morse Code to Text with Arduino
http://hackaday.com/2015/02/10/converting-morse-code-to-text-with-arduino/
Morse code used to be widely used around the globe. Before voice transmissions were possible over radio, Morse code was all the rage. Nowadays, it’s been replaced with more sophisticated technologies that allow us to transmit voice, or data much faster and more efficiently.
[Dan] decided to take a shortcut and use some modern technology to make it easier to translate Morse code back into readable text.
Decoding Morse Code with an Arduino and a Microphone
https://www.marginallyclever.com/blog/2015/02/decoding-morse-code-arduino-microphone/
In the Arduino Starter Kit there’s a piezoelectric speaker and a tone generator. I’ve shown you how to make music with the piezo and I’ve shown how to produce Morse code with the tone generator.
But what if you’re receiving Morse? Why not teach the Arduino to translate it back to English and learn how to use a microphone at the same time? So now I present to you, in four Arduino sketches, how I decoded this particular audio signal.
