    How To Make Your Sneakers Into Music Makers #ArduinoD14

    How To Make Musical MIDI Shoes via thobson

    Like many people, I often find myself unconsciously tapping my feet, whether it’s along to a song or out of some nervous habit. As fun as that is though, I’ve always felt as if something has been missing. If only I could trigger the sounds of say, a rabid pack of furious jungle beasts instead of those boring old toe taps. Or, you know, drum sounds or something. I guess that’s cool too.

    Well, now my dreams have been realized! In this “tutorial” I’ll show you how to go about making a pair of awesome musical shoes.

    This Vending Machine is Now Cyborg Friendly #ArduinoD14

    With the help of an Adadfruit RFID/NFC Shield, this ATM no longer requires credit cards, from hackaday.

    Don’t you hate having to pull out your wallet or cellphone in order to pay for something? What if you could just wave your hand and transfer money that way? Well [David] did, so he decided to do something about it. He made the vending machine in his hackerspace, FamiLAB, cyborg friendly.

    The problem was, the vending machine wasn’t technically his to play around with… so he had to do this hack without actually modifying the machine itself — which we admit, actually makes it quite a bit more interesting!

    But first, why is [David] even doing this? Is he a cyborg or something? Well, not quite, but he’s quite enthusiastic about bio-tech (is that what we call it now?) — anyway, he has NFC implants in his hand, and magnets in his fingertips to give him a sixth “electro-sense”. Wanting to take the most advantage of these augmented abilities, he put together this clever NFC credit card emulator.

    To read his hand, he’s using an Adafruit RFID/NFC Shield stuck on the front of the machine, with an Arduino Mega 2560 to control it. To get around messing with the credit card unit, he’s placed a solenoid next to it, which is close enough that when energized with his information… the credit card machine reads it. Whether or not you like the cyborg action itself, what [David's] put together is pretty incredible. He has detailed instructions and material on GitHub if you’re interested in knowing more.

    Adafruit PN532 NFC/RFID Controller Shield for Arduino + Extras: We’ve taken our popular Adafruit PN532 breakout board and turned it into a shield – the perfect tool for any 13.56MHz RFID or NFC application. The Adafruit NFC shield uses the PN532 chip-set (the most popular NFC chip on the market) and is what is embedded in pretty much every phone or device that does NFC. This chipset is very powerful, and can pretty much do it all, such as read and write to tags and cards, communicate with phones (say for payment processing), and ‘act’ like a NFC tag. While the controller has many capabilities, our Arduino library currently only supports reading/writing tags, and does not support phone-to-shield communication, tag emulation (which requires an external ‘secure element’ only available from NXP) or other more advanced features at this time.

    Turn a Trash Can Into an EVE Costume

    eve costume

    EVE is one of the most charming characters in WALL-E, and when Instructables user drwave’s daughter wanted to dress like her for Halloween, he took charge and built it. It all started with a trash can, and the costume is an inspiring example of using everyday objects in cosplay. He paired the trash can with EL wire, a paper lantern, and more. Making the shoulder supports was the trickiest part of the build, but he figured it out:

    We decided the best way would be to build some “wings” that would sit atop the wearer’s shoulders. This is the strongest and leads to the least fatigue of any of the ideas we came up with.

    To make it work, we started with a plastic top from an IKEA container, and using a Skil saw, cut out two wings that we bolted to the inside of the can, above the arm holes. Another important thing here was to get some foam (that we covered with fabric) and attach it to the wings where they will rest on the shoulders. We attached the fabric to the foam and then that to the wings with hot glue, but we used two bolts and washers to attach each wing to the can.

    The Beautiful Imagery of Alejandro Jodorowsky’s #Dune

    dune

    Frank Herbert’s Dune is a sweeping epic filled with alien worlds and beings. Not only are the landscapes rich, so are the characters and costumes and politics. The story has been adapted for the screen a few times, but Alejandro Jodorowsky’s unique vision never made it to completion. His take was surreal. He wanted viewers to feel as though they were tripping without any drugs. Concept art showcased by BoingBoing shows off Jodorowsky’s plan, and so does the new documentary titled Jodorowsky’s Dune.

    Adafruit is focusing its Halloween celebration and plans around Dune this year, so it’s only appropriate to give this documentary attention. You’ll be intrigued by Jodorowsky’s imagination and perhaps it will inspire you to come up with a new Dune costume!

    NEW PRODUCT – Anemometer Wind Speed Sensor w/Analog Voltage Output

    1733

    NEW PRODUCT – Anemometer Wind Speed Sensor w/Analog Voltage Output: An anemometer is a device used for measuring wind speed, and is a common weather station instrument. This well made anemometer is designed to sit outside and measure wind speed with ease.

    To use, connect the black wire to power and signal ground, the brown wire to 7-24VDC (we used 9V with success) and measure the analog voltage on the blue wire. The voltage will range from 0.4V (0 m/s wind) up to 2.0V (for 32.4m/s wind speed). That’s it! The sensor is rugged, and easy to mount. The cable can easily disconnect with a few twists and has a weatherproof connector.

    In stock and shipping now.

    Mark Miller shared:

    My latest version of the CNC lathe for wood and plastics. This model uses the Ps2 joystick teach system I have been making and allows you to manually create a part and then make copies of that part as the data for the movements are stored as you create the part. The board with the display on the left is the DRO which indicate position of the X and Y, you push the joystick down to toggle between them. A hex file is created as you create the original, and is transferred to a PIC. I have made several more versions of this and am currently making a small mill, drill and foam cutter that will use the same system. The entire machine is mostly made of Lexan bits and pieces and a few inexpensive motors.

It enables you to access the raw power of the camera. You can get the functionalities you would usually find on a DSLR camera on to a cheap point n shoot camera. The camera’s battery is puny and had only enough juicy for maybe an hour. Not enough if you want to take time lapse shots. So saw a few hacks where you can replace the battery with a dummy one and connect it to a external power source. The same product is available from canon for a price of 70$!!! That’s inane given that the camera itself costs just about 100$ So gave it a shot with what I had lying around at my home and this is what I came up with.” (read more)

After you cut off all those knubs place two pieces together and move them back and forth. Hear anything? No? Great! Now then, turn them over so that the single flat end faces you.

After some research, I found out the Adafruit Neopixel Matrix 8×8, which is very easy to apply because it uses a just a single wire interface and simple handy library. So, I used two matrix of this, which gave me a display of 16 rows and 8 columns of RGB LED (or pixels). For powering, I used a Lithium Ion Battery of 3.7V 4400mAh.

This project involved several Adafruit products including a 3.3v Trinket, a NeoPixel stick, a FLORA Accelerometer/Compass Sensor, and a Lithium Ion Polymer Battery. All of these components were chosen for their size and their light weight. The idea was to have a subtle yellow glowing effect under the car while it was at rest and while the car was in motion going down the track the pixels scroll from front to back with a brighter, different, color. The faster the car goes, the faster the pixels scroll. In addition, every time the car goes from scroll to rest, the color of the scrolling pixels changes to a new color for the next race. The car received many complements and oooh’s and ahhh’s. Thank you Adafruit for all of the great products that allowed us to add something fun and unique to our Pinewood Derby experience!” (read more)

    Instructables user brokenpipe created a one man version of the parade in a costume: “In Illustrator, I made a template to mark out all of the holes that I’ll need to drill to mount each ball [ping pong ball]. The balls I ordered were 38mm in diameter. Apparently, in 2000 it was decided that the “official” size of a ping pong ball would increase from 38mm to 40mm. It doesn’t matter whick size you choose, as long as you know what you’ve got. In my template, I added an extra 2mm between each ball just to allow some room for error when mounting the balls. I needed a firm base which would be large enough for the matrix so I went a local Target to see what I could find. I ended up getting a black plastic drain board. As you can see from the image, the size worked pretty well.” (read more)

    This Tiny Arcade Machine Holds a Raspberry Pi @Raspberry_Pi #piday #raspberrypi

    This tiny desktop arcade is fully functionally thanks to a raspberry pi, from eetimes.

    For many of us, there is a certain wonderful feeling that bubbles to the surface when we think of arcades. The many hours spent huddled around a game, pouring our hard-earned quarters into the machine. The shouts of frustration as your friends can’t beat your high score. The ridiculously sore fingers from mashing those buttons for far too long. Unfortunately, recapturing even a bit of that fun is difficult.

    Steve Smith managed to come up with a great way to recapture a bit of his arcade fun. He decided to put an arcade cabinet on his desk. This itty-bitty arcade machine you see is fully functional and loaded with games. Housed inside the tiny cabinet is a Raspberry Pi loaded with Mame, an emulator for a game system.

    This specific version of Mame is called PiMame and can emulate several different video gaming systems. You can find more information on PiMame here, if you want to run it on your Raspberry Pi.

    Make an inexpensive wi-fi enabled media center for your car using Raspberry Pi! #piday #raspberrypi @Raspberry_Pi

    NewImage

    MAKE has a great new tutorial up for a Raspberry Pi powered car computer.

    I have always loved those old TV series with futuristic tech in those futuristic vehicles, like Knight Rider, Airwolf, and Street Hawk. So it got me thinking about how easy it would be to add a computer to a vehicle. Now I know it’s been done before, and a quick Google search shows multiple companies making very complex vehicle computers, but at a large cost.

    Well, I thought, my Raspberry Pi is the perfect device for this.

    • It’s cheap
    • It’s very small
    • It’s got small power requirements (runs off a micro USB car charger)
    • It’s got flexible video and audio outputs (HDMI and Composite RCA for video, HDMI and 3.5mm audio jack for audio)
    • And best of all, you can change operating systems by simply switching out SD cards.

    Below is a photo of the Raspberry Pi running the excellent media center-type operating system Raspbmc which is perfect for browsing and playing your media collection using a media center remote or something similar, as shown in the Parts list.

    Tutorial – Adafruit 1-Wire GPIO Breakout – DS2413. Running out of pins on your Arduino? Get this!

    Microcontrollers 1551 Lrg

    Tutorial – Adafruit 1-Wire GPIO Breakout – DS2413 @ Adafruit Learning System.

    Pins are precious in the microcontroller world. How many times have you needed just one more pin? Sure, you could step up to a Mega and get a whole bunch more, but what if you really just need one or two? The DS2413 breakout board is the perfect solution. Each DS2413 breakout has 2 open drain GPIO pins and a 1-Wire interface. Just one of these boards will give you 2 pins for the price of one. But you can keep expanding from there.

    You can put as many of these boards as you want on the the 1-wire bus and still control all of them with just one Arduino pin. Each chip has a 48-bit unique address, which means (in theory*) you could have as many as 2 * 2^48 pins controlled by just one Arduino pin! What could you control with 562 trillion pins?

    How to – Automatic monitor color temperature adjustment… DIY f.lux @JustGetFlux

    Light Rwrzevc

    How to – Automatic monitor color temperature adjustment @ The Adafruit Learning System.

    Staring at a computer monitor all day is quite stressful. Moving your gaze from the cold, white light of a monitor to warmer indoor light is especially jarring to your senses. Programs like f.lux and Redshift were created to ease this strain by adjusting the color temperature of your monitor. However these programs don’t measure color temperature of light in the environment and instead guess the temperature based on location, time of day, and sunrise/sunset time.

    This project will show you how to build hardware that measures the temperature of ambient light and automatically adjusts your monitor color to match. With just a simple RGB color sensor and an Arduino or FT232H-based cable, your computer can easily sense and react to light in its environment.

    Before building this project, it will be helpful to familiarize yourself with the color sensor guide.

    NEW PRODUCT – Large Enclosed Piezo Element w/ Wires

    NewImage

    NEW PRODUCT – Large Enclosed Piezo Element w/ Wires: This large (30mm diameter) piezo element is nicely enclosed with mounting holes so you can attach easily. Piezo elements convert vibration to voltage or voltage to vibration. That means you can use this as a buzzer for making beeps, tones and alerts AND you can use it as a sensor, to detect fast movements like knocks. You can also use it under a drum pad to make a drum/crash sensor.

    It’s rated for up to 12Vpp use but you can also use 3 or 5V square waves and its plenty loud. For music use with an Arduino, check out the Tone tutorial. For sensing, the Knock tutorial is your guide! There are thin wires attached, we plugged them into a solderless breadboard, but they might too thin to plug in directly into the Arduino socket headers.

    In stock and shipping now.

    Winning the secondary school category, this entry stood out amongst some outstanding projects in the category. The judges said it demonstrated good use of the hardware and software as well as showing superb team work. Remembering to take the right number of pills at the right time can be stressful, particularly for those who are elderly or very sick. This automated pill dispenser makes managing medicine easier: the Raspberry Pi connects a pill dispenser with the person’s GP, who can program the administration of the drugs through a website. Correct dosages drop out of the Raspberry Pi controlled pill dispenser at the specified times. Meanwhile, if sensors detect pills haven’t moved once dispensed, an alert is sent to a family member who can remind them.
