We have updated the default code to use only 2 tabs on line 210. This was previously using 3 tabs, causing the Chromebook to shut itself down before enrolling.

If you are still encountering this issue, please let me know and we can identify the line that's causing the issue.

Big thanks to +Adam Robinson for helping to identify and fix a lurking bug in the code. The Arduino Create file has been updated, so if you're running into problems, try cloning the project again.

The addition of custom user attributes to User Gopher makes it possible to add non-native student information, such as grade level, homeroom teacher, assigned devices (for a 1:1 program), etc.

I'm keen to hear how folks are using this feature. Since it's flexible enough to support many different uses, I hope to hear lots of cool ideas!
The team at Amplified Labs is excited to announce that User Gopher now supports custom user attributes.

You can install and try the free version of User Gopher from here:

What are custom user attributes?

We all know that G Suite comes with standard directory fields, like "Employee ID" or "Cost Center," but custom user attributes allow administrators to extend this to include custom-defined fields.

With custom attributes, you can:

- Add even more data you want to record, like Student ID, and assign different data types to special these value fields, such as number, date, and email.
- Control whether you want the information to be public to all users in your organization, or private to administrators and the individual user.

User Gopher now makes it a snap to view and maintain these custom field values from Sheets. Learn more:

Thanks to the contributions of Centipede user James Norton, Centipede for ChromeOS versions 58 and above now has a more reliable WiFi connection method. The code is now updated on Arduino Create, so you're ready to rock the new code as soon as you program your Centipede.

I'm happy to see this community so active - it helps us keep Centipede at its best!

Centipede is growing up! We are incredibly proud of the impact our many-legged friend has had on the painful process of enrolling large numbers of Chromebooks. In fact, it is so popular that when Google released ChromeOS version 58, we immediately got to work building a new code base to accommodate the new enrollment process.

Centipede now has improved features, such as the ability to skip the Asset ID screen, or disable sending anonymous data to Google by default.

You can access the code for ChromeOS version 58 or higher by visiting

The Centipede page on the Amplified Labs site is now updated with the newest information.

Heads up to everyone - there's a widespread issue with Apps Script's PropertiesService - a core service used by most add-ons - that's affecting a lot of tools. If you see an error "Data Storage Error" pop-up, it's related to this issue.

You can help prioritize a fix by starring the linked issue.

I have an awesome table that's using a sheet shared with a group (who have accounts on various domains). The sheet is not public, so it does require sign-in. However, when a user sees the prompt to log in, the button has no action attached.

Heading over to and signing in fixes this. Is there something I need to do to allow the sign-in button to work? The site is private as well, shared with only the group members. Could it be CAJA removing a click handler or something?
