Hi Everyone!

Hope things are going well on your end! It's been a busy week here at Sonnet, and we have a couple of updates to share with you. Let's dive in!

Manufacturing Updates

On the manufacturing side, there aren't too many updates. We are still waiting for the PCBs for both the Wi-Fi module and the Sonnet Mesh Module to come back before starting the SMT process.

While we are waiting for the PCBs, we are continuing to fine tune the scripts that we are using to test the boards as they are coming off the assembly line. One of the the things we are trying very hard to optimize right now is the amount of time it takes to test each Sonnet. Right now the scripts takes about 450 seconds to run (approximately 7.5 minutes). This may not sound like a lot, but in comparison, the SMT process for each Sonnet takes less than a minute each. Reducing the length of the testing procedure is somewhat of a delicate balancing act where we need to test the boards as thoroughly as possible without using too much time. The most time consuming part of the testing procedure is flashing the firmware on the Wi-Fi module (180 seconds) and the microcontroller (120 seconds) on the Sonnet. As a result, most of our efforts over the past few days have been trying to optimize the flashing procedure. We have made a bit of progress so far, but there's still a lot of room for improvement. We will keep working to improve the flashing procedure and keep you updated when we make any progress.

Software Updates

On the software side, we just started implementing the notification system for the Sonnet Web App. The notification system allows the Sonnet to send "push notifications" to your browser when certain things happen such as when you receive a message or a SOS alert. Normally, notifications like these are done through push notification servers over the Internet such as Apple's and Google's servers. However, since the Sonnet devices are intended to be used in environments with no Internet connection, the traditional approach doesn't work. Instead, we need to implement notifications through a different set of APIs called local notifications. So far we have gotten the basic functions to work (so the Sonnet Web App can send and receive local notifications), and next we will need to connect it with the various functionalities in the app, so that the right notifications can be sent and received at the right time as the events take place.

In addition, we will also need to implement a URL addressing system within our Web App. Currently, the Web App just has one URL endpoint, and in order to navigate to a specific page within the Web App, you will need to first open the app, and then click on the buttons that lead to specific pages. What we need to do is to allow each URL to map directly to each page on the Web app. This will allow clicking on the notification to take a user directly to the page within the app that requires your attention.

That's it for now!

Have a wonderful week everyone!

Hello Everyone!

Welcome to the first update of 2018! We hope everything is going super in beginning of a brand new year! It has been a busy week here at Sonnet. Here are the updates:

Manufacturing Updates

This week, the manufacturing of the PCBs (printed circuit boards) in the Wi-Fi modules and the Sonnet Mesh Modules have started. PCB manufacturing is usually the very first step in electronics manufacturing because it acts as a foundation that mechanically supports and electronically connects all the components that goes into a product.

The PCB on its own doesn't do much, as it's only a sheet of fiber glass sandwiched between two copper layers. Once the PCB manufacturing is done, electronic components will be placed on the PCB via SMT (Surface Mount Technology), which is just a fancy term to describe that the components are soldered on the surface of the PCB. The SMT process itself is a bit more complex and involves robotic arms placing individual components on the PCB. We will be sharing videos when we do SMT for the Sonnet in a few weeks. After the SMT process, we get the following:

Software Updates

After some careful consideration, we have decided to include the crystal oscillator in the production version of the Sonnet. We had designed the PCB so that the microcontroller can use either an external crystal oscillator or an internal oscillator, and our original intention was to use the internal oscillator, which would reduce the complexity in manufacturing (crystal oscillators are typically soldered onto the PCB manually). However, one of our backers, Kean, pointed out that variation in temperature could potentially cause enough change in frequency to corrupt serial communication between the Wi-Fi Module and the microcontroller. Although we didn't run into any serial communication problem when we run our tests this week, we made the safe choice to include the external oscillator given that the Sonnet will primarily be used in the outdoors, which can potentially have large temperature variations. We have already made modifications to the microcontroller firmware to reflect this change. As this modification does not involve any change in the PCB, we don't need to re-apply for FCC/CE certification.

That's it for now!

Have a wonderful week!

Hi Everyone!

Happy holidays! It has been an extremely busy and productive week here at Sonnet. Let's jump straight into some updates!

Manufacturing Updates

We are very happy to announce that the manufacturing of the Sonnet has officially started!

On Tuesday, we received news from our FCC/CE testing lab that we have successfully passed the requirements for FCC as well as CE certifications, and that they have submitted the test results to the corresponding agencies to have the Sonnet certified. As soon as we received the news, we got in touch with our manufacturing partners and told them to start the manufacturing process. The manufacturing process is primarily divided into 5 parts: 1) manufacturing of the Sonnet Mesh Module; 2) manufacturing of the Wi-Fi module; 3) manufacturing of the baseboard, which connects the Sonnet Mesh Module together with the Wi-Fi module; 4) product assembly into the plastic enclosure; and 5) final product testing.

However, the timeline for the manufacturing turned out to be longer than anticipated. The end of the year is typically a very busy time for electronics manufacturers in China, and as a result, our manufacturing partners provided us with a 5-to-6-week delivery timeline as opposed to the typical 3-to-4-week timeline we had originally anticipated. This will push our delivery timeline approximately 3 weeks back. We will be working closely with our manufacturing partners next week to come up with strategies that can potentially speed up the manufacturing process, and update all of you with a more specific delivery timeline.

Software Updates

On the software side, we spent the majority of the week fine-tuning the testing firmware we will be using to do quality control as the Sonnets are coming off the assembly line. As mentioned in a previous update, the testing firmware performs a series of tests on the hardware to determine if the manufacturing process has completed successfully, and flash the Sonnet with the final production firmware that will be used by all the users. One of the issues we addressed this week is that in approximately 2% of the cases the testing firmware fails to flash the production firmware onto the device. This was as a result of a small bug in the networking driver on the testing firmware that fails to connect to the Wi-Fi and download the production firmware. We resolved this issue and so far the issue seems to have gone away.

In addition, we spent a lot of time testing the stability of the microcontroller firmware that runs the Sonnet Mesh Protocol. One of the most important bug we had discovered is a small inaccuracy in the calibration of the crystal oscillator. When we were developing the firmware early on, it was done on a development board that featured an external crystal oscillator (32kHz). On the production version of the Sonnet, we use the crystal oscillator built-into the microcontroller (8MHz). We had made some adjustments to the firmware previously to account for the difference in frequencies between the external and the internal crystal oscillators, but we had made some calculation errors. The result of this was that some serial communication between the Wi-Fi module and the microcontroller were scrambled, and required the message to be re-sent. We fixed the bug by making a couple of changes to the oscillator calibration calculation.

That's it for now! Thanks everyone!

Hello Backers!

Happy holidays! It has been a very busy week for all of us here at Sonnet. Let's dive into some updates!

Manufacturing Updates

This week, we started the manufacturing process for the lithium polymer batteries that will  be powering the Sonnets. At the battery factory, we had an in depth tour of the whole facility and learnt a lot about the lithium polymer battery manufacturing process. For example, we learnt how batteries of different sizes are manufactured, how the batteries are thoroughly tested before assembly into the finished products, and how the various battery chemistries differ.

Stress testing chambers for the batteries. These include forced-discharge tests, thermal shock tests, short circuit tests, mechanical shock tests, etc.

In addition, we are very close to completing the testing procedure for the Sonnet. We have consolidated most of the individual component testing procedures into the overall testing procedure that we will run on each Sonnet as they are coming off the assembly line. We ran into some issues where the testing script freezes half way through the execution. We believe this is a result of some lose connection between the testing rig and the testing unit. We are working hard to isolate and eliminate the cause of the freezes and to finish the testing procedure for the Sonnet.

Software Development Updates

This week, we spent more time to work on the configuration page on the Web app. We've completed most of the features including Wi-Fi network/access point configuration, firmware upgrade, and viewing system information. We are still working on password-protecting the administrative settings so that only the owner of each Sonnet can make changes to these system settings. We plan to have this feature completed in the next couple of days.

In addition, we spent a significant amount of time this week fixing a problem with the microSD cards. Because both the microSD card and the flash storage on the Sonnet communicates with the main processor using SPI, we experienced a bug where the system refuses to boot in to the flash memory whenever a microSD card is inserted into the Sonnet. Initially we thought we had made a hardware mistake that caused the microSD card to somehow interfere with the flash storage. Fortunately, after three days of debugging, we identified the issues as a software bug in the bootloader of the Sonnet that made it unable to distinguish between more than one SPI-driven storage devices. A fix has been implemented, and the Sonnet boots up normally with or without a microSD card inserted.

That's it for today! Thanks everyone!

Hi Everyone!

We hope everything is going well on your end! It has been a busy week here at Sonnet. Let's get started with some updates!

Manufacturing Updates

This week, a few members of our team have once again traveled to Shenzhen, China to get ready for the production of the Sonnet. For the next few weeks, we will be focused on completing the testing procedure for the Sonnet, and finishing up components sourcing. This will allow us to launch into production as soon as the FCC/CE certification is completed in a couple of weeks.

In addition, we have also started designing the packaging that will house the Sonnet. Sonnets are sold in multiples of 2, 3, 5, and 10. Instead of designing four different packaging sizes, we decided that it would be much simpler if we designed just a single packaging that houses one unit of Sonnet, and then bundle multiple units together to form the tiers. Because we will be shipping four different types of USB power adapters, a challenge we ran into while designing the packaging is to allow different adapter formats to fit into the same packaging. As you can see from a picture we posted in update #16, different adapter formats have different dimensions. To accommodate the difference in dimensions, we designed the packaging according to the length of Type F (Used in Europe, South America, India, etc.), and the height of Type G (Used in UK, Ireland, Malaysia, Singapore, etc.). To securely hold the adapters in place, we designed a thermoformed internal tray that grasps each adapter at the base (which shares the same dimension across the different formats). We will post a picture of the packaging once a sample has been produced.

Software Development Updates

This week we started working on Web app features that allow users to configure various settings on the Sonnet. Some of these features will be used to set up the Sonnet when you power it up for the very first time, and some of these features will be accessed regularly, depending on your specific use cases. For example, basic configuration features include:

  • Connecting the Sonnet to Wi-Fi networks
  • Changing the access point SSID and password
  • Upgrading firmware to the latest version
  • Mounting/unmounting micro-SD cards and USB drives
  • Viewing system information

While designing these configuration features, we paid close attention to ensure that the system is expandable because we plan to add other configuration options (such as Internet-sharing, channel switching, manual frequency/power output override, etc.) in the future. In addition, we are also designing these features with security in mind. One of the most important security features is password protection of the configuration page. Because multiple users can share a single Sonnet simultaneously, during the setup process, you will be asked to enter a "master password" for the Sonnet that allows you to access the configuration panel. This allows the Sonnet to distinguish the owner of the device from other users and prevents users who are sharing your Sonnet from making unwanted configuration changes.

That's all for today! Have a great weekend everyone!

Thank you!
