Step 2: When My Eyes Were Stabbed by the Flash of a Neon Light...

You just need to follow the fine tutorial on Adafruit's Learning System. http://learn.adafruit.com/led-ampli-tie/overview

I used the Dynamic sketch for the Ampli-tie.

Mod the code if you want to change the animation of the lights.

The only major change is that I will not be connecting my components with conductive thread. Instead, I am using real wire from ribbon cable.

The connected row of 16 individual NeoPixel boards will be replaced with a set of two NeoPixel rings controlled by the same pin. Note that they need 5 volt power so they are connected to vBatt.  The 3.3 v is not enough to power the NeoPixels and they will act wonky,  I tried.

Note that I have modded my Flora to have leads from the pin outs and terminated with female headers. The power supply pins and GND have a ganged  female header to accomodate the multiple common connections.

The microphone amplifier breakout board came with a set of 6 male header pins.  I soldered 3 into the board (+3, GND, data). The other 3 unused pins I wasn't sure of what to do with.  Spare or were they to make your own cable?  I just soldered them perpendicular to the ones on board and made a right angle connector. Clip off the excess leads. You can then terminate a cable with a female header connector for use. It makes for a flatter connector.  Connect this to the 3.3v pin of the Flora.

Test your circuit.

I haven't looked at the code closely yet but you can create multiple instances of the Adafruit_neopixel strip commands to run off of different pins.  I wasn't sure of how to do that yet but you can just put the data pin inputs together so that the driving signal goes to both Neopixel rings in parallel. The original code was to graphically convert for 16 pixels and not a chained strip of 32 for both rings if you put the data out pin to the data in pin of the other.

<p>Afraid not, @The End of A Heartache.</p><p>The Neopixel LEDs are current monsters. Those two rings, at full brightness, will consume a whopping 1700 mA of current. Solutions include permanently dimming the LEDs a little (they will still be very bright), lighting up one color at a time, and/or avoiding patterns that light every single LED the whole time.</p>
Looks great! Now find something to hide all the wires and it would look even better!
This is the prototype. And I &quot;borrowed&quot; the kid's headphones to<strike> sacrifice</strike> mod.
This is a great project and I have the same pair of sony headphone. <br> <br>The battery pack is huge Why not look for small lith-ion battery back on ebay. <br> <br>I have a micro battery pack 3.7v 200 Mamp Not sure if the ampere is right for the use :) but I want to try this out on my own headphone
I don't have a li-po battery pack...yet. Still working on using up the 48 pack of AAA from the wholesale club. You might be able to power up the Flora with that but I think the LED rings might take a little more juice. It also probably expects more closer to the 5v that USB puts out.
okie thank you for the information, with that in mind 2 li-po pack will do fine. I wonder whats the max voltage the Flora can handle. I know it can take up to 3 amps which is very powerful for such a small unit. I looked at the link which has more information about the Flora They did not tie in a USB to charge the battery or li-po and because the li-po can cause a fire hazard I agree with them working with light foam EPO RC airplane Li-po under charge gets very hot, have not measured temperature but I know you need at least a 10 minute cool down before charge and use on each pack. Only good thing about a lipo pack is a 2 cell to 3 cell unit :) which can give you 500 mamp to 1 amp of current.
Li-pos do pack more punch that regular alkalines or old chemistry rechargeables. I have used 9volts on my regular Arduino and I think both that and Flora have onboard voltage regulators. 12volts may be the max but probably not recommended.
Killer Project!
Pretty sweet. They look really amazing in the video. If only the battery pack and wires could be hidden somehow without opening the headphones, it'd be ready for everyday wear...
My real headphones have a cushion wrap around the headband so it wouldn't be hard to cover all the electronics with it and hide it there. You should get a few of the bare NeoPixel chips to fool around with. They are really bright and don't need external resistors.
how much is the total cost?
You can go to adafruit.com to price what you need <br>$25 Flora arduino <br>$7 Mic amplifier breakout <br>2x $10 NeoPixel RGB LED rings or you can get a bunch of the SMT NeoPixel chips or microboards to configure in your own pattern <br>$12 li-po battery or $2 battery case <br>misc wire/connectors/tie-wraps/tape <br> <br>Depends on what you have $50 - $75? <br>
Hey, get on down and strutt your funky stuff, man!
boogie oogie woogie...
