I'm still on the fence about whether to connect all eight LED strips through their communication line, or have them wired individually.  In the meantime, I decided to check out some Neopixel code to see what my options were.  Obviously that was fun!     So, although I'm able to hack this code somewhat, I'm still not clear about some of the INT values.  So, I don't think I can make a decision yet about connecting the communication lines.  It appears to be easie ...
For our furry cosumes, I want the orange leds in one costume to trigger red neopixels in another costume to light up.  However, whenever I shine the light of the orange led strip on the FLORA color sensor the color sensor shuts down after about three readings and the serial monitor stops printing readings.  Then I have to reload the tcs34725 sketch twice before the color sensor will begin again.  This happens whether the color sensor onboard led is on or not.  I am running th ...
I'm sorry that it's been a long time since my last post - sorry about that. Let's get to good stuff!   After testing the parts and proving that they work, I felt compelled to see how hard it would be to make a compass out of them. Testing a little further, I find that the FLORA Accelerometer/Compass to be a little mixed, performance-wise. At low velocity (so that the only acceleration is due to gravity) the magnitude of the acceleration vector is right around 1000. I had initially assumed ...
I took all of my things to Cape May thinking I would do some coding tests with the individual Neopixels.  Between all the walking around and all the Victorian architecture, I never got to it.  I did get very inspired to someday create a lamp based on the Frank Furness gasolier I saw in the Physick house (only with LED's, of course).  Speaking of LED's,  I think Neopixel LED Strips are rather precious, so I've been sort of putting off cutting my 5m strip.  Afterall, it di ...

Jacket ideas

Posted by hifromkatie Aug 23, 2013
Unfortunately I haven't found much time this week to do anything more on the electronics side of the project, hopefully tomorrow I'll be able to get back on to it and get a nice chunk of it sorted as I've got nothing else planned.     I have however been thinking about the jacket I'm going to attach the kit too.   My first choice is to make the jacket myself, as I've been wanting to make another jacket since making a smart-casual cotton jacket last year, so here's my chance  ...
Holidays are over! So I finally have the time to work on my ColorCam again! I was getting kinda tired of having to set up my circuit with the alligatorclips over and over again. So I took some time to sew all my pieces to a bit of fabric. This saves me a lot of time setting up, and it gives me a nice prototype to work with!     As of yesterday I also have a working Flora board. I had some trouble getting the Flora to update my code, I kept getting these errors. A small chip on the ...
This project is my second wearable project. The materials have improved significantly in the past two years. My first project was a Lilypad based Tieduino.   The thread was silver instead of stainless steel, the pixels were monochromatic, and unchainable. The thread did not stand the test of time. You can see below it is quite blackened with tarnish. This inhibits the conductivity in the circuit. The silver thread also seemed to snag in the fabric more often than the stainless.   ...
Working on the basics to ensure the parts are all in good order. I clipped the leads to the FLORA and the GPS and ran a simple echo sketch to verify the GPS is talking.   The next step is to code the math calculate distances to the Geocache. I knew I was going to need math but I'm now realizing I'm going to be doing vector arithmetic to calculate headings and distances! Fortunately, I found a nice site to check my math. http://www.movable-type.co.uk/scripts/latlong.html It gets me to abou ...
Well it might not be a good storyboard but its my storyboard and i’m sticking to it (Unless somebody points out a big mistake and I change it) I have annoted each step but will put the text under each photo in case you can’t read my really bad handwriting.     Visitor walks up to a museum. Their ‘Heart on the sleeve’ is flashing randomly to show that they aren’t currently in a museum. But as they get closer the gps chip detects that they are going into a ...
I just couldn't stand the Adafruit Neopixel LED Strip 30 sitting in its box any longer.  It looked so lonely and dark in there.  So, I decided to take the risk -- hook up the FLORA with the LiPo (2600 mAh) and strip. I was so scared a wire would overheat and I pictured all those old movies with the mad scientists pulling the big switch and big puffs of smoke everywhere, but I decided that Tesla and the others must have done their share of crash and burn.  My turn.   ...
Hi, I've been busy gathering ideas for my umbrella.  Here's the mighty beast -- a large dome umbrella with silver trim and a ginormous handle that's even too big for Mary Poppins.  I can tell you that no matter what size the power supply, the horrible crook will be getting removed!  Other than that, it is pretty darn cool. Speaking of power supply, the other night I involved two guys at my hackerspace in a friendly debate on powering 5m worth of neopixels.  The results were r ...
Here is the next update for the Get Closer challenge.  Our mailwoman is starting to drop off materials for our costumes   DC plugs, LED strips, faux fur.  We love the faux fur.  I am underwhelmed by the brightness of the LEDs.  The picture below makes the strip appear brighter than it is.      I went with the typical 5m, 12V led strips available everywhere.  The blue one was the first to arrive.    Here is the math.  First, determ ...
Just a quick update on the current progress, which may help others in using the GPS module:   Firstly I started off with the Adafruit Flora GPS parsing example, and used this to become familiar with the GPS library.   I then based my code to start with around this to output current location and a hard coded destination to the Serial Monitor   My next step was to output "You've arrived" if the two matched and ":( Not home" if you haven't" This was very patchy, so I decided I nee ...
It took a while to come,but after watching the delivery tracking website for what seemed like days on end and having to explain what a AdaFruit Flora is so the kit could be put through customs. Well after all that I now have my kit. So lets have a quick look at whats in the box Some very boring cardboard, but at least it came well packed Getting close now Really close Ta - Da The Full Kit   The Actual AdaFruit Flora Itself   The Sewing stuff   Bags full of goodness (Mainly ...
I spent last week camping with my 5-year old. I didn't take my laptop with me, but I did take some stuff to make the camera I had in mind for my project This is how my work-/sewingstation looked like! An herd of sheep standing on the other side of the water kept looking at me and loudly commenting on the progress.. BAAH!   Since my camera has to be suitable for small children, I decided to make it nice and soft. So the interior is made out of two pieces of foam. I cut out a few holes ...
I finally received my package on Monday!   Here's my very own GPS Starter Pack! [I am not entirely sure why I was compelled to open the bag of test leads]   And here are a few other things (Tactile On/Off Switch, FLORA  Lux Sensor, FLORA Accelerometer/Compass Sensor, Magnetic Pin Back, JST-PH Battery Extension Cable, Woven Conductive Fabric, and FLORA Color Sensor)!   Everything arrived safe and sound. The packaging was very good and everything comes in its own (stat ...
I've spent the last couple of days reading up on the Adafruit Neopixel RGB LED strips -- especially how to cut them apart and use them in combination.  The FLORA doesn't scare me as much as the strips LOL.  On the Adafruit forum, I've seen mixed responses on dealing with my set-up of sending multiple strips the same code.  One response is "fanning multiple strips from one pin is voodoo" and another is that "four strips should be able to run off one pin".  In my case I have ei ...
I got back from a week's holiday at my parents late Sunday night, which was a great time away although I also was really happy to get back to my own home especially as my Flora kit was here waiting for me!   Last night I finally had time to open the box, and i was really pleased with it, as others have already done an unboxing video I will save uploading another as the kits are the same. Here is a picture of what I found inside the kit:   Firstly I went to download the software, I ...

Arduino mobile

Posted by chris.carter Aug 6, 2013
Still a ways to go in unpacking at our new place (and building our light-up costumes) but I found enough time for a small arduino project (and time to blog about it ).   Our baby is really turning on to his mobile but we did not like the music that the old turning mechanism made nor did we like turning the knob to reload the spinning every 40 seconds.    Arduino+Servo+8.4V battery pack = indefinately turning mobile with no annoying music.  Used the Arduino servo "Sweep" li ...
After looking at the images of tattoos that I posted recently and thinking about my ideas for the project I decided there was only one thing for it and that was to break out the felt tips and get something on paper. I wasn't too bothered exactly what i drew but I knew that just the act of putting pen to paper would help to crystallise my ideas by giving me something to look at and think about.  I knew I wanted to represent a museum gallery and exhibits in it. So I drew a circle with eight ...
After a week Ellison, Rowan and I have just about finished moving in to our new place in Minneapolis.  The weather is amazing and the people as nice as advertised.  The FLORA package arrived while Rowan and I were working on building ikea furniture and we stopped long enough to open the box and get excited about our first arduino project together.    Our goal is to make a family of furry light-up costomes whose lights/colors interact with one another.  With effort we ...
Today the Flora kit came in! All kinds of sensors, wires and of course the Flora itself came out of a black cardboard box (check Leslie's or Bill's unboxing videos to see exactly what was in the box). So as soon as my son was sleeping, I set to work   I have to point out that I have zero experience with Arduino or electronics, so I had no idea what to expect or where to start.. So I checked the Adafruit website and there I found the tutorials on the Flora. First up was the 'Getting starte ...
I would like to apologize for not getting this entry up sooner. This week was a little crazy since my second child was born early this week. Wife and the baby are doing well, but life with the toddler at home has been a bit hectic. I was very happy to see that my FLORA kit arrived today.   Motivation for My Project   My wife and I try not to get too wrapped up in the extreme consumerism that is so prevelant here, although I am an Apple fanboi. We value experiences way more than stuff ...
I love coming home and finding boxes on my doorstep! My FLORA kit showed up today and I thought I would do a little public unveiling of the contents.     Having just come back from many days of vacation, I think I'll be taking on trying to gamify geocaching a bit.   Step 1: Design a circuit with the GPS sensor and the neopixels. Step 2: Decide on the form factor and how I want to display the program output. Step 3: Build it! Step 4: Programming and debugging.   Fo ...
I was so excited to get home today to open my parts.  I honestly did not peek before recording!!  Spoiler Alert if you are in this challenge and have not yet received your box.   ...
