DGP – Vox Treble Booster V1.0 by diyguitarpedals is verified! Check out the build kit PDF.

 

Powered by Intel Edison and featuring a splash of purple, Anouk Wipprecht‘s 3D printed Synapse dress and headpiece communicate the wearer’s emotions via lights.

“The dress’s headpiece is fitted with a sensor that track the wearer’s attention level and focus to monitor fluctuations in the wearer’s “internal” mode – where attention level is usually high (around 80%). This functions internally to train your attention span, but also communicates externally by telling others that you are in a high state of focus and “do not disturb” while concentrated on a difficult task…One of the other sensors embedded in the dress monitors proximity: if the wearer feels like someone is invading her personal space, the lights in the dress can give off up to 120 watts of brightness, telling the other person to back off. The dress has a camera on the front that can capture a picture whenever the subject feels either most tense or most relaxed so she can later track what was making her feel that way”

Make, Mod, Create

Every day, millions of people are working individually and together to make, mold, and mod the world into a better, more enjoyable place. Crafting the details of Oracle‘s glowing armor, rebuilding a Yak, collecting environmental data, and developing new technology are just a few of the many forms of making. Whether you recognize it or not, dear reader, you are one of them.

Everyone is a maker and our world is what we make it.” - Dale Dougherty

No one is too old to learn a new skill, and breathing life into almost any creation you can imagine is becoming easier. Supplies are more affordable, new tools are more user friendly, websites such as youtube and Instructables bring lessons into your home, and D.I.Y. communities are sprouting like explosive polymerization eliminating the need to be the reclusive tinkerer.

If you are having trouble seeing yourself as a maker, or are toying with the idea of making, but uncertain where to start, try following Adam Savage’s Ten Commandments of Making:

  1. Make something, anything. Getting started can be the most difficult part.
  2. Make something useful.
  3. Start right now. Do a mock up with the tools you currently have available. Never underestimate the versatility of everyday items.
  4. Find a project. Always pick a project that will get you interested in learning a new skill.
  5. Ask for help, advice, and feedback.
  6. Share. Share your techniques, your sources. What are you hiding?
  7. Recognize what you find discouraging, so you can work through it. Acknowledge failure is (usually) part of the project, and an incredibly useful learning tool.
  8. Measure carefully. You can always trim a little more, putting it back can be tricky.
  9. Make things for other people.
  10. Use more cooling fluid. Caring for your tools and using them properly will help them last longer and make using them easier.

 

If you identify as a creative type and want to hang out with other creative types, you might try checking out your local chapter of Dorkbot, drop in for an open house at a makerspace, or if you’re in the Portland area, drop by our Monthly Maker Meetup!

Staff Picks for the Week of 1 December 2014

Laser safety, GPS tracking, and more! Our community has been busy. Below are a few of our favorite projects from the past couple of weeks.

 

If we had a “Best Safety Feature” award, it would go to Cereal_Killer for this 17mm Laser contact board. It prevents people from hurting themselves with a laser by reversing the bias, preventing the current from flowing if the battery is inserted + end forward (like how you normally would in a flashlight). 

 

dbtayl‘s Runner’s GPS shows the current distance traveled and the time taken to travel that distance. It was sponsored by the University of Minnesota’s ECE Envision Fund. Recently, this awesome project was featured on Hackaday!

 

Max‘s electronic compass with tilt compensation features 36 blue LEDs and 4 red LEDs that are individually controlled from GPIO on the AVR microcontroller. The project also has a 3-axis accelerometer and 3-axis magnetometer.

 

P-MOSFET PWD Shield by SmittyHalibut enables you to switch to the common cathode instead of the common anode. Rather than using a N-Channel MOSFETs like most FET shields, this shield uses P-Channel MOSFETs which switch the positive. This allows it to work with loads that have a common ground (like this aquarium light )

DIY Light Up Plush Monster Tutorial

Follow the steps below to create a light up monster friend of your very own!

Follow the steps below to create a light up monster friend of your very own!

 

Skill level: Beginning to intermediate

 

Knowledge: Designing a basic circuit with LEDs in parallel and hand sewing a running stitch. If you’re sewing the entire project by hand, a bonus knowledge of blanket stitch for sewing around the edges might be helpful.

 

Supplies:

  • 4 sheets of felt
  • 1 ft tulle or other findings you want to add
  • 2 non-metal buttons
  • spray craft adhesive
  • embroidery floss
  • 2 LEDs
  • CR2032 battery
  • Battery holder (You can either make your own or purchase one like this one from Adafruit)
  • Conductive thread
  • Monster pattern- Draw your own or use one of the many awesome free templates available online

 

Tools:

  • Needle nose pliers
  • Hand sewing needle that fits easily through the contacts of your battery holder
  • Needle threader- While not absolutely necessary for some, I find threading the conductive thread or embroidery floss near impossible without one.
  • Scissors
  • Optional: Sewing machine
  • 2 different colored markers

 

Step 1: Trace your template onto the felt and cut it out.

 

Step 2: Decide where to put your LEDs, and draw your circuit using different colored markers for your positive and negative traces.

 

Step 3: Use a straight pin or your hand sewing needle to stab the fabric to loosen it where you want to insert the LED.

Insert your LEDs through the buttons and into the fabric with the negative leads on top and positive on the bottom. This will make sewing your circuit easier.

 

Step 4: Use your needle nose pliers to coil the leads of the LEDs. This will allow you to secure them to the fabric with conductive thread.

 

Step 5: To easily sew our circuit from the LEDs on the front fabric to the battery holder on the back, we’ll need to first use embroidery floss or regular non-conductive thread to sew the top of your monster’s head together.

sew fold original

 

Step 6: Using about 2 feet of conductive thread, sew the negative trace of  your circuit from LED 1 to LED 2 to the battery holder, making certain to secure the leads to your fabric by sewing through the spirals we made earlier. After tying off your thread, add a drop of fray check or clear nail polish on your knot. Wait a few seconds for it to dry, before trimming the excess thread. This will help prevent your knot from unknotting.

hand sew neg1

 

 

Step 7:  Repeat step 6 for the positive trace of your circuit.

 

Step 8: Insert your battery and test the circuit.

test circuit1

 

Step 9: Using embroidery floss, sew any additional features, such as a mouth, eyelashes, or patch work style stitches.

 

Step 10: Using non-conductive thread and either a straight stitch on your sewing machine or a blanket stitch if you’re hand sewing, sew most of the way around your plush friend, leaving a 1-2 inch opening.

 

Step 11: Fill with stuffing and close the opening.

 

Step 12: Enjoy  your new friend!

Staff Picks

Welcome back to a new edition of Staff Picks!

This selection from our community includes a graphics display, a bonus round for Squishy Circuits, an interactive biofeedback installation, and a crazy clock that keeps time for you and your Martian friends.

 

The ILI9431 Display (320×240) for the Teensy 3.1 by PaulStoffregenenables high resolution color graphics, and can be used with the Adafruit_ILI9341 library or the Optimized ILI9341 library.

 

Pulse & Bloom is an interactive biofeedback installation by Saba Ghole, Shilo Shiv Suleman, Rohan Dixit, Heather Stewart, Luke Iseman, and Samuel Clay. The pulses of participants are visualized by illuminated mechanical lotuses, ranging in 8 to 18 feet tall. When a participant presses the pulse sensor, their heartbeat is visualized by flashing lights.

 

Squishy Duino by rexxar-tc improves the Squishy Circuits experience by adding an analog-to-digital converter across the dough. The read voltage will change as people manipulate the dough. This circuit allows for the ADC values to vary the tone of a speaker, or change the individual colors of an RGB LED.

 

This open source hardware and firmware Crazy Clock by nsayer is a DIY novelty clock maker’s dream. A variety of firmware loads allow for your clock to tick “randomly” while keeping perfect time. Most of the options tick 86,400 times per day for the approximate 18-months that your AA will last, with the exception of the Martian clock.

Staff Picks

This edition of Staff Picks includes everything from adaptors and bubble displays to a dehydration alert system for your plants and a dual voltage regulator.

 

MultiAdaptor from Opendous features “multiple overlapping footprints for any occasion: up to 28 pin SOIC/SO (1.27mm pitch), up to 28-pin SSOP/TSSOP (0.65mm pitch), up to four SOT23, up to three SC70, one MSOP-10 (0.5mm pitch), one SOT223, and one SOT-143. All in a 0.8″ wide DIP board. The header pins are staggered to allow press-fitting them while soldering.”

 

Chirp is a plant watering alarm – as simple as that. You put it into the soil near a plant and it emits a tiny chirp when the soil is dry, reminding you to water the plant. Chirp uses capacitive humidity sensing as opposed to resistive humidity sensing, this means, it does not make an electric contact with the soil, avoiding electrode corrosion and soil electrolysis and resulting in better accuracy and longer battery life.”

 

Cameron Tech’s Dual Voltage Regulator comes in handy when you find yourself needing to “supply both 5v to an Arduino (without its own voltage regulator) and 3.3v to attached sensors at the same time.”

4x4x7Segment by sirkha features four HP 4-digit 7-segment bubble displays on a board designed to be mated with the Adafruit HT16K33 breakout, quickly allowing you to display four values using i2c. 

 

 

The Small VAWT Controller by Blueberry controls the current output of a small vertical axis wind turbine. The board features “a micro-controller to sense turbine RPM, input voltage, and input current, and send a PWM signal to a MC34063 buck converter, and if need be a signal to the gate of an SCR to shut down the turbine.”

Beautiful Boards #3

Whether it’s an image or unique board shape, we love it when makers add a little extra something to their boards.

Staff Picks for the Weeks of 27 July and 4 August 2014

Nsayer‘s USB Micro ISP v0.3 is a voltage-agile AVR programmer that improves on the original design of SparkFun’s Pocket AVR programmer, adding quite a bit of versatility.

  • The mini USB receptacle is replaced with the more common micro USB.
  • Added a blocking diode before the pull-up resistor. The problematic pull-up resistor to the buffer chip’s output, which provided a path from the ATTiny2313 controller’s output pin through the pull-up resistor to the target power making the Pocket AVR unsafe for 3.3 volt systems.
  • Added a 3.3 volt LDO and two-way jumper that allows you to select a target power of 5 volts, 3.3 volt power, or none.
  • The 2313 controller is powered from the 3.3 volt supply. When not supplying the target power, this allows the programmer to be agile across the entire allowable supply voltage range for every AVR chip it can program. It can program chips being powered from 1.8 volts to 5 volts.

 

CymaSpace’s unique effects pedal is design to convert stereo audio into a dynamic and musically responsive light show all in a small form factor useful for touring musicians and artists. Click here to see it in action!
