If you're here you're likely one of the first owners of a L3D Cube (8x8x8 edition). Hi there you lover of the future, you! This section of the site is intended to help you create and share apps on your Cubes. Let's get started!
Each L3D Cube 8x8x8 edition comes with 512 RGB LEDs mounted in an array, powered over USB (or via the L3D Cube Battery Shield), and connected to WiFi. The brain and WiFi connection center of the Cubes is a Particle Photon, which can be programmed like an Arduino. There's also a built in microphone and accelerometer in each Cube for music visualization and interactive apps.
The magic of owning a Cube comes with being a part of the world's first volumetric app sharing community, CubeTube! Each Cube can download new apps from CubeTube.org with a click of a mouse or finger -- no programming needed.
But for any programmers out there - HELLO! CubeTube is designed to help you create and share like a boss. You can now write code directly in CubeTube's browser window, preview your programs in a simulated 3D Cube, share the apps you create on CubeTube more easily than ever before, and fork other people's code so you can build new Cube apps with startling speed. More details in the CubeTube sections below!
There are two types of L3D Cubes so far: the 8x8x8 edition with 512 RGB LEDs and the 16x16x16 edition with 4096 RGB LEDs. This documentation section currently only addresses the 8x8x8 edition and will be expanded to include the larger 16x16x16 edition in Spring 2016..
Each L3D Cube 8x8x8 edition comes with 512 RGB LEDs mounted in an array, powered over USB, and connected to WiFi. The brain and WiFi connection center of the Cubes is a Particle photon, which can be programmed like an Arduino. There’s also a built in microphone and accelerometer in each Cube.
LEDs: 512 RGB surface-mounted LEDs.
The specific type of LED used is a WS2812B, made by WorldSemi. There are 8 LEDs to each LED reed, and each LED reed is identical, connected into a custom base PCB.
Power: Any USB power supply or USB port can power your Cube. We also include a 2 amp USB adapter with your cube that can run off of house voltage anywhere in the world.
There is a 1.7A current limit built into the baseboard of the 8x8x8 Cubes.
8x8x8 Edition with 512 RGB LEDs
In 30 minutes flat, you can transform that box of parts into a 8x8x8 L3D Cube!
Watch this extremely short assembly video.
Or download the full instructions here.
You can power your cube with the included 2A USB power supply, or by plugging it into any USB port on a laptop or other power supply.
The 8x8x8 L3D Cubes come pre-loaded with four demos:
The four demos will loop forever by default. You can stop the loop and play just one selected demo by tilting left, right, and forward.
The loop can be restarted by reconnecting to power.
If you already have a L3D Cube, you’re in the very earliest adopter group - a pioneer, you might say. You can connect your Cube to WiFi through the Particle App. These are instructions for how to do so come directly from particle.io.
Each Cube is controlled by a processor called the Particle Photon. This is the small circuit board that you plug your USB cable into for power.
When you plug in your 8x8x8 L3D Cube for the first time and switch the slider-switch at the back of your Cube to "Online", you should see the Particle Photon start to blink a blue light. If not, then press down the "Join WiFi" button next to the Particle Photon.
Once the Photon on the underside of your Cube is blinking a blue light, it’s ready to be connected to your local WiFi network via the Particle App.
Download the Particle App to your phone from the App Store or Google Play . (If you don’t have a phone that can download apps, no problem...you can still get your Cube online, it’s just a little more involved of a process to Connect over USB)

Your phone must be connected to the Wi-Fi network that you want to connect the Photon to. Wi-Fi Hotspots generated from the phone you are running this app on typically will yield an error claiming there is no Wi-Fi available.
In this case, please try to Connect over USB and enter your Hotspot credentials manually.
When connected to Wi-Fi, the app will automatically fill the SSID field with the name of the network that your phone is connected to. Enter your Wi-Fi password and hit connect.
This connection process can take up to a minute, so be patient. The closer your phone is to your Particle Photon, the faster it will connect. Once the Photon hears the signal, it will go through the following sequence of lights:
Once the Particle Photon has connected, your phone will "claim" the Photon and attach it to your account. Then you’ll get to name your Photon. If you’re uncertain, you can confirm that the claim process was successful by logging into the Particle Web IDE and clicking the "Photons" icon at the bottom of the page. Is your Photon listed? Great! The world is perfect.
If you are connecting multiple Photons, you’ll go through this naming process for each Photon. You’ll know which one is which by the rainbow signal.
Once your Cube’s Particle Photon is connected to WiFi via the Particle App, it needs to be claimed in order to be associated with your account. This is what lets you control your Cube and keeps anyone else from doing so.
If you use the mobile app to set up your Photon, it should claim it automatically. However if you connect your Photon over USB, or if the claiming process is unsuccessful, you can claim it manually.
The easiest way to manually claim a Photon over USB is to use the Particle Command Line Interface. Once you have this installed, you can simply type particle setup and follow the instructions.
Alternatively, if you have troubles installing the command line tool, you can get the Photon’s ID over serial and claim it via the build site. You can do this by opening a Serial connection to the Photon and pressing the i key (see the above instuctions for connecting over USB). It should show you a number like this:
# Example Photon ID55ff68064989495329092587
Then open up Particle Build and click the ’Photons’ icon. Click the button that says ’Add a Photon’, and enter your ID in the text box.
When you move to a new WiFi locations, you can get your Cube’s Particle Photon back into Listening Mode by clicking the big round "Connect to WiFi" button next to your Cube’s Particle Photon, on the underside of the Cube. This will not delete any programs you have stored in the internal memory of the Particle Photon, and just clears the WiFi credentials and puts the Particle Photon back into WiFi Listening Mode. Then repeat the process above to connect to the new WiFi location.
When you first go to CubeTube.org, click the "Join or Log in" button. Log in using the particle.io username and password that you created when you were connecting your Cube to WiFi in the previous step.
You can browse the Gallery and see simulations of most apps in your browser when you mouse-over the app thumbnail.
If you like a particular app and want to load it onto your Cube, choose one of your online Cube from the dropdown menu and click "Send to Cube". If you chose a "Cube Required" app, immediately after you click the Send to Cube button, the LED on the Particle Photon under your Cube should start to blink purple (indicating it is downloading the app). This download process will take 10-45 seconds.
BIG NEWS! You can now write code directly in the browser window on CubeTube, fork other people's programs (e.g., "Sketches"), and easily simulate and share your programs with the rest of the CubeTube community.
You can get started by forking another user's sketch, or you can start from scratch by clicking the blue "Create" button.
Here’s an Instructable on How to Draw Sweet 3D Graphics for LED cubes - there’s even a cube simulator so you don’t even have to wait for your cubes to get started.
This is a list of hardware, firmware, & software improvements we’re strongly considering implementing in follow-up revs of the L3D Cube. These improvements are based on ideas at Looking Glass Lab & within the community via the Kickstarter comment boards and the CubeTalk Forum.
The very first L3D Cube owners are just getting their Cubes now and we’re in the process of making a Troubleshooting list.
For now, if you’re having trouble connecting your Cube to WiFi or downloading Apps from CubeTube, please head over to the Forum and post your question there...someone in the community or within the Looking Glass team will help out!
We will then compile the most frequently encountered issues in this section.
