It’s Turkey (Project) Time.

via SparkFun: Commerce Blog

In the U.S. we're celebrating Thanksgiving tomorrow, mainly by over-eating at a very strange time of day, but if you're like us, also by taking this opportunity to put our own electronics where they maybe wouldn't be otherwise.

No Thanksgiving tradition is as sacred as overcooking your turkey, sometimes dramatically, which is why we have - not once, but twice - offered DIYs that revolve around making sure you don't. Without further ado, the data-collecting Turkey Temperature Probe and the Tweeting Turkey Timer . Don't say we never did anything to help.

Have a great holiday! We're thankful for you. We mean it.

The Safety Scarf

via SparkFun: Commerce Blog

The days are getting shorter and shorter my friends. WINTER IS COMING. Night is falling at an unnaturally early hour (in my humble opinion), and I have been finding myself out and about after dark more than during daylight.

alt text

With the LilyPad 10-year anniversary in mind, and a hot set of new LilyPad products, I decided to make myself a winter accessory using sewable electronics that would both keep me warm and keep me safe this winter, all while still looking stylish as heck.

Enter the Safety Scarf (which is more like a cowl, but honestly, calling it what it is would ruin my carefully-crafted alliteration and that's a sacrifice I am not willing to make).

THE SAFETY SCARF:

alt text

The Safety Scarf is a very soft and cozy wearable project that is embedded with a LilyPad UBS Plus, a LilyPad Light Sensor, and two sewable LED ribbons. When ambient light is low, the LED ribbons will automatically turn on, making the wearer more visible to drivers, bikers and other pedestrians - ultimately making them safer. The material quality of the LED ribbon makes them look like piping along the seam - giving them a subtle, clean aesthetic.

As some of our dedicated readers will know from my wearable rants, functionality is just one part of a successful wearable project. I could go on for hours about this, but when designing wearables, it is always important to consider what makes a successful garment as well as what makes a successful functional interactive project. All of this is to say, there is a fun layer of complexity when designing wearable projects that needs to be considered, and because of that, the wearability and versatility of this project are probably my favorite things about it.

alt text

alt text

As shown in the images above, the Safety Scarf features an infinity scarf style. On extra cold nights, the user can loop it around twice, giving extra warmth and comfort. On more temperate nights, the user can wear it loose, allowing more breathing room. Since it is comfy and cute, with the electronics mostly hidden, the user can also turn the scarf off and simply use it for warmth during the day. The circuit switch and charging port are easily accessible too! Does anyone else out there get this excited when form and function meet in such harmony?!

…Seriously. I’d love to know. Please comment below.

Friday Product Post: Swiftly Sweep

via SparkFun: Commerce Blog

Well hello there, everyone! We are fresh off the release of our new SIK v4.0 last week, but we saved a ton of new “big ticket” products for this week to prepare you for Black Friday and Cyber Monday. Today we are happy to bring you a massive DIY kit that turns your Scanse Sweep 2D scanner into a 3D scanner (make sure to read the product page thoroughly, as there are a few important pieces of information there), a more economical version of the new uArm, a shield that adds an IMU and motion-sensing capabilities to your ESP32 Thing, a rainbow of Fairy Lights, and a pre-order for the IBM TJBot now available to the general public! Alright, it’s a big week and we don’t want to waste any more time teasing you with all these new products, so let’s jump in and take a closer look!

2D is too flat, but 3D is everything we know!

Scanse Sweep 3D Scanner Kit

KIT-14482
$399.95

The Scanse Sweep 3D Scanner Kit is an advanced 60-piece DIY kit that gives you everything you need to assemble a 3D scanner using your Scanse Sweep LIDAR sensor (NOT INCLUDED). Outdoor 3D scanning has been around for decades, but has traditionally been much too expensive for home use. This kit aims to put this powerful technology into the hands of makers who want to develop and experiment with applications for long-range 3D scanning. The only tools you will need are a soldering iron, wire stripper, small Phillips-head screwdriver and 2.5mm ball-end hex key.

Please make sure you read the description on the product page all the way to the end, as there are quite a few things to know before you purchase this kit!


U can get an extra Arm with this new Swift.

uArm Swift

ROB-14341
$499.95

The uArm Swift is a high-grade desktop robotic assistant that can be utilized in many more applications than its predecessors, the uArm Basic and the uArm Metal. Built around an Arduino Mega 2560, the uArm Swift is an open source, DIY-friendly robotic arm platform developed for makers and educational purposes. This little bot is extremely easy to use; almost anyone can learn how to play with it in a few minutes. The uArm supports visual programming as well as Arduino, Python, GrabCAD and ROS, providing plenty of options for a wide range of users. Unleash the maker inside and get uArm to make your ideas happen!

The uArm Swift has a repeatability of 5mm with a maximum payload of 500g and is one of the most affordable open source robotic arms on the market. If you are looking for a more precise version of the uArm Swift, check out the uArm Swift Pro.


Where did you come from, where did you go?

SparkFun ESP32 Thing Motion Shield

DEV-14430
$19.95

The SparkFun ESP32 Thing Motion Shield is a versatile, motion-sensing addition to our ESP32 Thing. With the Motion Shield’s onboard LSM9DS1 IMU, small movement changes can easily be detected, while larger movements and time traveled can be detected with the addition of a GPS module via a large JST port. In addition, we have added breakout pins to attach any serial device, as well as a microSD card slot to log all of your data. All you need to do is solder on headers, and your ESP32 Thing Motion Shield will be ready to detect any type of movement!


Fairy Lights - Warm White (2.5m)

PRT-14500
$4.95

Affectionately dubbed “Fairy Lights” for their similar appearance, these LED string lights are a great way to light up any project with no soldering required. The insulated strings come in 2.5m lengths with one LED every 10cm for a total of 25 LEDs. Unlike previous iterations, these LED strings come with a pre-attached battery pack with a power switch and two CR2032 batteries already installed.

We currently offer the Fairy Lights in Warm White, Cool White, Red, Green. Blue, Purple and Orange.


IBM TJBot, a Watson Maker Kit

KIT-14515
$149.95

When the IBM TJBot originally went live, it was only available to certain individuals, with limited stock and for a short time. Now this cute little robot kit is available for pre-order to anyone who wants one! We plan to have the TJBot built up and available to ship by mid-December, just in time for the holidays.


That’s it for today, everyone. There are a lot of new goodies to check out and play with or to pick up for great gifts! As always, we can’t wait to see what you make with these parts! Shoot us a tweet @sparkfun, or let us know on Instagram or Facebook. We’d love to see what projects you’ve made!

Thanks for stopping by. We’ll be taking a break next week due to Black Friday and will be back in two weeks with even more new products. Be sure to check our website next Friday to see our fantastic sales! We are pretty confident you’ll like what we have to offer!

Enginursday: Audio Reactive Wearable Fiber Optic

via SparkFun: Commerce Blog

Alright, so I’m in the middle of a bit of a larger project at the moment; I’ve been revamping my Fiber Optic Light Suit — incorporating better controls, redesigning 3D-printed parts and now adding audio input! The video below gives a little demo and explanation of the basics of this neat little feature.

Hardware

What I have is an MSGEQ7 Audio Spectrum Analyzer taking its input from SparkFun’s MEMS Microphone Breakout. I wanted something that could do quite a bit of math for my application and still have enough clock cycles left over to run my LEDs at a particularly high frame rate, so I’m using a Teensy 3.6 to read the input from the equalizer. However, the pins on the Teensy run at 3.3V logic and are not 5V tolerant, so I’m also using a logic level converter to get all of my logic levels where they should be. All of this is pretty standard if you’re making a multichannel audio equalizer.

Software

One thing I’ve always wanted to implement was software to map the frequency of sound in the environment around me to a hue of color. To accomplish this, I ditched the standard RGB (Red, Green, Blue) scheme of color data and went instead to HSV (Hue, Saturation, Value). Hue, which is the color value (e.g., red or aqua) was mapped on a scale from 0 to 255. I divided this into seven equally spaced steps in hue around the color wheel (Numerical values for ROYGBIV) and assigned the value (or brightness) for each different hue to each channel from the audio spectrum analyzer. The channels are then averaged and written to the LEDs. In order to get started, use the Arduino library manager to download the libraries for the MSGEQ7 as well as FastLED, which I find to be a great tool for controlling strips of LEDs using as few clock cycles as possible.

Once you have those libraries downloaded, the below example code should get you started mapping frequencies to hues of color.

#include "FastLED.h"
#include "MSGEQ7.h"
//LED Setup
#define NUM_LEDS 32

#define DATA_LEFT_ARM 11 //yellow
#define CLOCK_LEFT_ARM 13 //blue

CRGB leftArm[NUM_LEDS];

//Equalizer Setup

#define pinAnalog A1
#define pinReset 16
#define pinStrobe 17
#define MSGEQ7_INTERVAL ReadsPerSecond(5000)
#define MSGEQ7_SMOOTH true

CMSGEQ7<MSGEQ7_SMOOTH, pinReset, pinStrobe, pinAnalog> MSGEQ7;

void setup() {
    FastLED.addLeds<APA102, DATA_LEFT_ARM, CLOCK_LEFT_ARM, RBG, DATA_RATE_MHZ(24)>(leftArm, NUM_LEDS);
    MSGEQ7.begin();
}

void loop() {
    bool newReading = MSGEQ7.read(MSGEQ7_INTERVAL);
    if (newReading) {
        visualizeAllChannels();
    }
}

void visualizeAllChannels() {
    CRGB spectrumHue= (0, 0, 0);
    uint8_t colorValue[7];
    double colorNormalize[7];
    uint8_t hueMixer[7] = {10, 15, 225, 30, 80, 180, 150};
    for (uint8_t channel = 0; channel < 7; channel++) {
        //hueMixer[channel] = 36 * channel;
        colorValue[channel] = MSGEQ7.get(channel);
        colorNormalize[channel] = colorValue[channel] / 255.0;                                              
        spectrumHue = spectrumHue + (CHSV(hueMixer[channel], 255, colorValue[channel]) / 7);    
    }
    for (int LED = 0; LED < 32; LED++) {
        leftArm[LED] = spectrumHue;
    }
    FastLED.show();
}

This means that a bass note will show up as red, mid range as green, and treble as blue. In the video, mostly mixes of greens and blues are visible as the audio input is coming from my tiny, high-frequency cell phone speaker. The speaker in my office hits red in all of the places that I would expect and gives a much fuller range of colors.

I wonder what it will look like at a live show with decent audio quality. For now, all I can do is wonder. Please let me know what you think in the comments below.
