MAKE things move with simple motorized circuits

Using inexpensive materials, you can MAKE things move by creating a simple motorized circuit. When you attach the motorized circuit to a base (a toothbrush head, plastic cup, etc.) you can make an analog ArtBot that is capable of creating a variety of randomized art. With endless possibilities, what will you design your ArtBot to do?

With all the digital technology around us, why would we want to make analog robots? Using inexpensive materials these little bots are a great introduction to circuits and allow for great engineering explorations involving simple design changes to experiment with cause and effect. There are even science competitions for these little bots: BrushBot Olympics, BristleBot Educational Robotics Competition, and many more. Even if you can’t physically compete in one of these competitions, try out some of their ideas and start your own competition with friends in your neighborhood or at your school.




  • toothbrush head (flat head works best)
  • scissors or pliers (have an adult help)
  • vibrating motor (tiny pager motor)
  • 3v battery (CR2032 coin size)
  • twist tie or rubberband
  • craft materials (pipe cleaners, foam strips, paper, etc.)


  1. Cut the toothbrush head with scissors or pliers.
  2. Attach the motor to the battery (align + and – sides).
  3. Attach motor/battery combo to brush with twist tie.
  4. Decorate the BrushBot.

Watch the Brushbots race.
Dip them in paint and watch BrushBots create art.
Tie a leash on them and take them for a walk.
Imagine where they would “live” and create them a habitat.

What happens if you add “legs?”
How can you control the path of the BrushBot?
Can you create an on/off switch to save the battery?
What happens when you use a different type of brush?




Using the same simple motorized circuit, you can make an ArtBot that can draw.


  • plastic base (cups and/or plastic containers)
  • scissors
  • vibrating motor (tiny pager motor)
  • 3v battery (CR2032 coin size)
  • drawing tools: pens, pencils, and/or markers
  • rubberband
  • tape
  • craft materials (pipe cleaners, foam strips, paper, etc.)


  1. Attach the motor to the battery (align + and – sides).
  2. Attach motor/battery combo to plastic base with rubberband.
  3. Attach drawing tools to make the base “stand up” on its own.
  4. Decorate the DrawingBot.

Watch the Drawingbots race inside a box.
Watch DrawingBots create art together.

What happens when you use a different type of base?
What other recyclable materials could you use for the base?
Can you create an on/off switch to save the battery?
What happens when you move the placement of the motor/battery?
How does the placement of the drawing tools impact its drawing?
How can you adjust the DrawingBot to draw circles? dots? straight lines? curves? dashes?

MAKE things light up with simple circuits!

Circuits are all around us but we normally don’t pay much attention to how they work. A circuit is a loop that connects volts from a power source (such as a battery) to an output (such as a light or motor). Learn more about the technical aspects of circuits from this tutorial on SparkFun.

In addition to traditional electronic components, circuits can be made out of a variety of conductive materials, such as conductive thread, conductive tape, or even conductive ink.

Our favorite introduction to circuits is to make things light up. Combining an LED light and a coin-size battery (3 volt CR2032 batteries are our favorite) you can make a simple circuit connection that has a lot of creative potential. Simply attach tape or a binder clip to keep the circuit connected and consider what you can turn it into…a ring, a pendant, a bow tie, a hair bow? The possibilities are endless! Follow these simple steps to create your own: LED bling tutorial

Advanced electrical concepts can be explored by extending this same concept of simple circuits into soldering electrical components to a printed computer board. We like to start to learn how to solder with this tutorial that creates a blinking LED badge.

Soldering is serious business and needs to have a lot of safety considerations, but with the proper precautions we believe that children of all ages can successfully and safely learn to solder as long as they have appropriate adult supervision. Learn more about soldering basics here and be sure to check out our favorite one-page soldering guide here designed by Super Awesome Sylvia.

Maker Play Workshops at San Marcos Public Library

Join us at the San Marcos Public Library for “Maker Play” workshops on July 10, 17, and 24 from 2-4 pm. Explore technology including 3D printing and simple robotics to bring your imagination to life with hands-on projects! This workshop is free and geared toward kids ages 7-12. Space is limited so please register through the SMPL website here.

This is a series of annual workshops that are in collaboration with Maker Camp, which supports a unique global summer camp experience for young artists and inventors ages 7-12. This year’s themes include: Far-Out Future, Flight, Fun and Games, Fantasy, Funkytown, and Farmstead, which will challenge every participant to learn new skills across a wide range of interests.

LED Binder Clip Bling

LED binder clip bling-ringBecause we just LOVE creating simple LED circuits, so we couldn’t help ourselves when we stumbled upon the idea of the LED Binder Clip Bling tutorial created by Jessica Henricks on the MAKE: magazine website (view her original tutorial here). Using simple materials, you can create an LED circuit with an easy on/off switch (the binder clip) to conserve the battery and transform it into wearable art.

Here is our modified one-page tutorial handout: http://tinyurl.com/LEDbling (shared GoogleDoc)

Consider adding a magnet and turning it into electronic graffiti (Make Your Own LED Throwie).

Inkblot Mandalas

Mandalas are a spiritual symbol that represent the Universe. Traditionally they consist of radial balance with at least four lines of symmetry. Inspired by Margaret Peot’s Inkblot: Drip, Splat and Squish Your Way to Creativity, we invite you to try to create a mandala using blots of ink or paint.


  1. Fold a piece of paper in half. Apply a dot or two of water, and a dot or two of ink or paint.
    • inkblot1
  2. Fold the paper, and apply pressure with the palm of your hand. Unfold.
    • inkblot2
  3. Finally, fold the paper horizontally, apply light pressure, and unfold. Now, what do you see?
    • inkblot3

Make historical and cultural connections by including additional instructional information about mandalas: http://www.mandalaproject.org/What/Index.html

Incorporate more inspiration by including additional artistic design concepts, such as those from our favorite inkblot artist: http://www.theinkblotbook.com/for-educators-parents/



Tessellations are a great way to create interesting design templates. Using rotation and translation, you can create a unique element out of a simple square. Check out this educational resources to understand more about the mathematical principles that make tessellations work: “The Math of Tessellations” http://www.mathsisfun.com/geometry/tessellation.html

Consider the various types of designs you can create with one tessellation. Can you create an animal or creature? Can you create a tessellation with organic and flowing lines?
