Send your littleBits circuits out into the world wearing SHOES! Now you can hold your circuits together and place them on any surface. Try magnet shoes on your refrigerator, hook & loop shoes on your dog’s collar, or adhesive shoes for more permanent installations. Check out the projects below for inspiration and be sure to visit our Shoes Tips & Tricks Page for more ideas.
Magnet Shoes in Action
Make a mailbox indicator light. This circuit sits directly on your metal mailbox (due to magnet shoes) and signifies when mail is placed inside. When letters are placed on top of the roller switch, the long LED on the exterior of the box shines bright. Out with the flag and in with the long LED! littleBits circuit: power + roller switch + wire + bright LED.
Hook & Loop Shoes in Action
Shoes on shoes — secure your circuit to a pair of sneakers to make these Stomping Shoes. The light wire lights up whenever you stomp down due to a sound trigger. All you need to do is stick an adhesive velcro adhesive strip to the sneaker, add hook & loop shoes to your circuit, lace up the light wire and start dancing.
Make a light-up dog collar! Design your circuit (we used a power module, a sound trigger, wires, and bargraphs) and lock it together with hook & loop shoes. Sew parts sections of a velcro strip to the collar, position the circuit, and watch the collar light up when your dog barks.
Adhesive Shoes in Action
Using adhesive shoes, secure your synth circuit to any material and make an instrument. We made a Keytar! The adhesive on the shoes sticks nicely to the acrylic surface of our keytar and holds the modules snugly in place.

Last week we had the pleasure of hosting Bilal Ghalib, a hacker aficionado and founder of both GEMSI (Global Entrepreneurship and Maker Space Initiative) and pocketfactory.org, at our offices in New York City. We asked Bilal to come spend time with us at littleBits and make the craziest project he could think of.
Not only did Bilal create a mind-blowing project with interesting interfaces that challenge the way we think about littleBits in combination with the physical and digital realms, his process truly showcased the power of littleBits as a prototyping tool.
Bilal was interested in how he could create an interface between the littleBits synth modules and his own music making tools (apps like Alchemy on the iPad) to make a more robust musical experience. His project has a number of physical and digital components that make up a multi-channel music-making machine.
“Piano Roll” Sequencer
The entire project is controlled by a “piano roll” sequencer that operates under similar principles to a player piano and is triggered by light. Bilal created a scrolling musical score by filling in dark spaces on an Excel spreadsheet and running it in between a series of 4 bright LEDs and 4 light triggers. When a dark square moves between a bright LED and a light trigger, a corresponding oscillator plays a note. This “piano roll” sequencer has four output channels and plays three notes. These sounds can be modified by adjusting the oscillators, but also by adding and mixing in other synth modules. The fourth channel, rather than producing a note, is connected to a long LED which lights up to the pattern of black squares on the scroll. The squares on this fourth channel are spaced at regular intervals and produce a pulse of light.
The light pulse put out by the long LED is read by a light trigger in a subsequent circuit that activates a drum beat in time to the “piano roll” sequencer. A normal pulse module could have been used to control the drum beat (the 2nd circuit), but with the light pulse, the drum beat corresponds with the speed of the DC motor that spins the scroll of notes, keeping the two circuits in sync with one another. The transfer of electrical signals between two isolated circuits via light is called opto-coupling. Not only is this a great way to sync up the two circuits, and it also helps the project to run more smoothly as each circuit has a separate power source. The larger and more complex a circuit gets, the more power it needs. This project also uses power adapters vs. batteries.
Conductive Servo Arms
The drum beat circuit is all based off a single pulse, but it produces three different rhythms simultaneously. This is done with a branch, a series of logic modules, and three servos. The servos are positioned on top of an iPad that has the Alchemy app open. Alchemy is a synthesizer app with a variety of sound sets and modification features (drum sounds were selected for this demo). The servo arms are dressed in conductive foam and wired to a copper pipe. When they are activated by the pulse signal, the conductive foam arms move up and down and touch certain spots on the iPad, creating different sounds of a drum rhythm. This conductive setup takes the place of a finger tap.
Logic-Based Drum Beat
This drum circuit, though controlled by one pulse, creates three different rhythms. The pulse goes into a branch where the three servos are connected. Before each servo are a series of logic modules (latches and inverters) that switch up the beats.
What’s great about this project is that you can modify the sounds and the rhythms by making physical changes (no programming is needed whatsoever). Switch up the rhythms by filling in squares on an Excel sheet, speed up the tempo by adjusting the speed of the dc motor scroll, add and subtract logic modules to mix up the drum beat, and change the quality of sound by experimenting with various synth modules.
A zoetrope is a device that produces the illusion of motion by rapidly spinning a series of static images. It is a classic invention with ancient roots and has gone through many iterations over the years. We thought we would put our own “spin” on the zoetrope using littleBits and 3d printed parts.
For this project, our circuit was relatively simple. It has a DC motor and three bright LEDs controlled by a pulse. We also used a button in combination with a latch in order to be able to turn it off and on.
If you don’t have a 3d-printer, but would still like to be able to use these parts, you can 3d-print our files via Shapeways. Shapeways is a 3d-printing marketplace and community. If you don’t want to go the 3d-printing route, try creating figures using Lego or clay.
You can also find all the 3d files for this project on Thingiverse.
We are very excited about some of the new projects that we’ve been working on as well as the projects that the littleBits community members are coming up with. In this post, we will showcase robots that react to their environments in a variety of ways and rely on no programming whatsoever. The following robots are able to navigate a space and each depends on a different set of sensors to do so.
Through a combination of LEGO and littleBits, we were able to create a super smart cockroach that reacts to its environment just like a real one would. It is able to navigate tricky spaces and it scurries when it is exposed to light. When it finds a dark place to hide, it lays low and stays put.
How it works:
Navigation – The two bend sensors act as sensing antennas to help the cockroach navigate its surroundings. When the cockroach approaches a wall, the closest bend sensor will be activated. This will cause the opposite wheel to stop spinning due to the inverter before the dc motor, steering the cockroach away from the wall.
Shadow Seeking – The cockroach has two light triggers. The light trigger is set on light mode, so when each of the sensors sees light, the wheels spin. When a light trigger sees darkness, it’s corresponding wheel stops spinning, making it so the cockroach turns toward the darkness. If both light sensors are in the darkness, the cockroach stops moving completely.
This smart little creature roams the table on a central wheel that is connected to a dc motor. Little plastic arms activate three roller switches on the side as they bump into cups and bowls, causing the robot to turn and try elsewhere. This happens because there is an inverter in between the first dc motor and a second dc motor positioned on the edge. More info about the circuit here.
This project, submitted by one of our community members, is a vehicle that is able to follow the twists and turns of a line made from black tape. It has two bright LEDs, two light sensors, and two dc motors. It works by illuminating the floor’s surface with the bright LEDs. The light sensors then pick up the reflected light from the floor. Lighter-colored surfaces (the floor) reflect more light than dark surfaces (the black tape). When one of the light sensors senses the lower reflectivity of the black tape, its corresponding dc motor slows down, thus turning the vehicle and keeping it on track.

Time to get fancy! This animated hat will surely impress your guests. Bright LEDs project a spinning image of Santa and his reindeer flying through the night on the wall of the hat. Just touch the pressure sensor at the top of the hat to activate the dc motor.
Candy is an important part of Halloween! However, eating all that candy can lead to cavities. Make brushing fun this Halloween by creating your own electric toothbrush! All you need is a toothbrush, rubber bands, a wooden block, and littleBits! This toothbrush also has a programmable timer so you can decide how long to brush your teeth for (the American Dental Association recommends brushing your teeth two times a day for two minutes). Show that sweet tooth who’s boss this Halloween.
This Lego cockroach behaves similarly to real cockroach, making it a great Halloween prop. It is able to navigate tricky spaces and it scurries when it is exposed to light. When it finds a dark place to hide, it lays low and stays put. See how this clever circuit combines bend sensors, inverters, and light triggers to create this lifelike interaction.
In honor of the littleBits Halloween Costume Contest, we whipped up our own Halloween costume. This glowing dinosaur can be made with the light wire and an old hoodie. Learn to use the light wire as a structural element and light up your night this Halloween. See project details here.
As the spookiest day of the year approaches, we here at littleBits have been cooking up some supernatural projects to trick out your Halloween. The interactions in both of the following projects are surprisingly haunting and would be a great addition to any haunted house or, if you are the Adam’s Family, a permanent wall fixture.
Great Uncle Edward
This portrait may just look like a normal photograph, but take a step closer and you will notice something very strange. The eyes in this portrait physically move, and not only that, they follow you wherever you go! We used an old frame, a photograph, motion triggers, a servo, and a series of logic Bits to achieve this unnerving interaction. This is one of our most complex circuits yet! Learn more here.
‘Come with us’, two small ghostly figures beckon. As you draw closer you hear a rattling sound. The figures suddenly quadruple in size and appear very close to you. Run away!!! The Ghost Projector uses a motion trigger and an inverter to switch between two ghostly images printed out on transparency paper and projected on the wall with bright leds. The images are angled in such a way that they appear in the same frame and alternate depending on whether or not you are detected by the motion trigger. More information about this spooky light trick here.
