Here was the drawing we included in our initial bid.     And we kind of got there but time ran out on us.  The failures just kept multiplying yesterday after we tried to take a video of them in action.  Here is a pic from yesterday.      Cute, but no effects were working because a button on Ellison's suit failed.    The problems continued into today when I accidently killed the arduino controlling her costume.  At that point Ellison and ...
In case anyone was wondering about the construction of our costumes, here are some pics.  We used fleece as a lining.  It is a very forgiving fabric to work with.  Then a fleece strip on top of that to run the LED strip through.  Elastic on top to secure it to the body.  Here is one set of arms, legs and hat.  Big push to get all the costumes finished this weekend.   ...
The coding is basically done, now for the construction.  Just wanted to let the other competitors know where we are 2/5ths of one costume complete (see video below).  These costumes are going to be hard to beat if everything comes together (and if I don't underestimate the amount of current it takes to run the LEDs).  I burned through a breadboard wire this morning experimenting with a boost converter.  Originally I intended to use 12v batteries but I already have a bunch of ...
I want the light in our baby's costome to have a sort of physical property where light drops to the bottom if the baby is lifted up and light rises to the top of the baby's costume if he accelerates down.  This is a little harder than Becky's brake light motorcycle jacket at adafruit because a motorcycle has a relatively constant deceleration over a long distance as the brakes apply force slowing the rider and bike.  When throwing an older toddler/child in the air you can get half a se ...
I feel like a student coming to Becky's office hours saying "I know I should be alot further along, but this is what I have."    One element of the costumes that I wanted to incorporate was one person's costume reading the light pattern of another which would culminate in a light pulse from both of their hands (ala Power Rangers).  The FLORA lux sensor makes it possible!  Now to incorporate it into a costume   ...
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 ...
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 ...

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 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 ...
