We Funded! And More News About Newt.

by Darian J

Thank you to everyone that pledged to purchase Newt, watched a stream, liked an update, or told a friend. We would not have reached our funding goal without your support. We’re excited about continuing our work on Newt and getting it into your hands as soon as possible.

To that end, let’s talk about the software that ships with Newt. We wanted to build software that was both functional and showcased the "art of the possible". Here’s what we’ve developed so far.

Timing functions

The Newt’s uses a RV-3028 as its real time clock (RTC). The RV-3028 was selected because of its ability to operate at low power and it’s timing functionality. It’s one of the few RTCs that support concurrent:

We use these timers to sound an alert (a repeating 5 second beep) when the alarm or countdown timer "fires".

Habit Calendar

The habit calendar was built to help users track progress of a daily goal or habit. This functionality relies heavily on the flash memory that comes with the ESP32-S2 (the microcontroller that powers the Newt). We use the flash memory to save the users’ daily "checks". The calendar is reset on Jan 1 of every year.

Location Relevant Information

The ESP32-S2 is a Wi-Fi enabled device; we’re able to use the external IP address of an internet-connected Newt in order to determine general (postal-code) location. This is then used to query and display the followng information:

Our thoughts on security

We take security very seriously, so here’s our stance on the software that ships with Newt:

What else are we missing?

The Newt has been, and will continue to be, shaped by its community of users - so please let us know what we should include. You can use the "Ask a technical question" form to ask about a feature or provide a suggestion. We look forward to hearing from you!
