The certification process has started!
about 4 years ago – Mon, Aug 31, 2020 at 01:38:12 AM

Doppler backers,

The certification process has started! In this update, we will go over what we did to prepare for the certification process, BLE connectivity, USB-C upgrades, and color matching.

Certification

First off, let’s talk about certification and what that exactly means. If you’re familiar with Alexa products, you may have seen the terms “Alexa Enabled”, “Alexa Compatible”, or “Works with Alexa” used somewhat interchangeably, which previously lead to some confusion as to the distinction between the different types of Alexa products. More recently, Amazon has made an effort to clarify its Alexa device ecosystem by implementing “Alexa Built-In” as the term for devices like the Doppler that have Alexa running on the device itself, like an Amazon Echo device, as opposed to devices that just have a skill, like a smart light bulb. In order to have a cohesive Amazon Alexa experience on all “Alexa Built-In” devices, like the Doppler, Amazon requires each and every product to go through a strict certification process. At the successful end of the process, you are eligible to say your product has “Alexa Built-in” and you can proudly display that banner on your Amazon listing and marketing materials.

Certification and testing are some of the least interesting bits of content for these updates that we can imagine, so instead of going into great detail about the various certification requirements, we are going to give a very brief overview and then tell you where we are in the process.

Before you submit your device to Amazon for certification, you have to make sure it follows Amazon’s requirements. We have been on top of these requirements since well before the Doppler launched and we have been checking every time we add a new feature that we are in compliance with the various requirements Amazon lays out. Once your device meets all the requirements Amazon has set forth, the real fun begins--self-testing. There are 5 self-tests that Amazon has: Functional, UX, Music, Security, and Acoustic. These various tests are all listed in Amazon’s documentation which is available here: https://developer.amazon.com/en-US/docs/alexa/alexa-voice-service/self-testing-process.html. We are going to skip some of these details in an effort to keep you reading and awake. The bottom line is that the testing took a lot of time and the Doppler now passes all of the self-tests!

One of the resources we used to help us pass all the self-testing is something Amazon built called the Alexa Qualification Tool (AQT). This tool uses multiple specially-tuned speakers in a specifically designed and laid out room and pattern to mimic different sounds coming from different places. For example, you’ll have one speaker say “Alexa, tell me a joke” accompanied by silence, then say the same thing with music playing in the background, then again with white noise playing. This will test the acoustic properties of the Doppler. If/when something failed or went wrong, we had to tweak the Doppler to get it to pass. Having AQT allowed us to run multiple tests much faster than without it. Even with AQT, it has been a time-consuming process to try to get everything working as well as possible. But it’s done and we have passed all the self-testing!

The vast majority of the time was spent on the issue of Alexa hearing herself saying “Alexa”, which we have mentioned before, and struggling with the DSP (digital signal processor) and audio system in general. Although this issue has now been tested more thoroughly and things are working much better, we can’t quite put the issue to rest. However, we think it’s good enough at this point to proceed.

We are confident that we now have a version of the software and DSP firmware working well and we are doing final acoustic testing over the weekend. Next week, each of these devices that we are currently testing will be sent to Amazon’s test lab for final certification. We aren’t entirely sure how long this certification process will take, but we are hoping that in 3 or 4 weeks we will have more information either way. Please expect the next update to be around then with (hopefully good) news. Once we get the green light from Amazon and the third-party security company we can start the shipping process.

As mentioned previously, along with the functional, UX, music, and acoustic testing that Amazon conducts, there is also a third-party security audit required for “Amazon Built-In” Certification. This third party security audit checks all aspects of the device to make sure that it is living up to Amazon’s strict security standards which guarantee both that the device is hard to hack and that no personal information can be obtained by someone trying to break into your home network through the Doppler. This audit is going to be done in Taiwan by an independent, third-party lab and we have two Dopplers ready to send next week to Taiwan. A lot of the last couple of weeks have been spent on writing internal documentation and double-checking these against Amazon’s requirements making sure that everything is up to snuff. We are confident that we will pass this audit as well.

Connection issues

While we’ve had lots of positive feedback from our Beta backers, we’ve also had some negative feedback. The vast majority of the issues and feedback have all revolved around the Bluetooth Low Energy (BLE) connection between the phone and the Doppler. When you don’t have a solid connection between the Doppler and the smartphone, bad and confusing things happen while you are using the app. We have listened to the Beta backer’s feedback and are now working on implementing WiFi-based communication between the Doppler and the smartphone. This is a decent amount of work on both the Doppler software side as well as the app team at our partner company, Zemingo.

The initial setup between the Doppler and the app will be unchanged and will use BLE.. Once the Doppler has successfully connected to your home network we will then be switching the communication method from BLE to WiFi. The only downside to this new connection protocol is that your phone will have to be connected to the same wifi network as the Doppler for the app to work. We are also investigating a cloud-based connection method for the Doppler so that you wouldn’t have to be on the same wifi network and could control your Doppler from anywhere you have an internet connection. For the developers in our community, yes we are using a REST API and you can expect a bunch of nerdy jokes about using a REST API on an alarm clock.

USB-C upgrades

We have discussed this a couple of times in previous updates, but we would like to carve out some time at the end of this one to discuss USB-C again. We have mentioned that we would be supporting a USB-C upgrade kit that would allow users to have three USB-A and three USB-C ports. Originally, this upgrade kit would have shipped with your Doppler and would not be pre-installed. Then we said we would pre-install the upgrade kit for you. Well, now we are ending up somewhere in the middle, where all backers who want a USB-C upgrade pre-installed will have that option, but we will also be offering a simple upgrade kit for those that want to upgrade after they receive their Doppler. We have written a little step-by-step guide (with lots of pictures) in our manual on how to upgrade your Doppler’s left-side USB-A ports to USB-C ports.  While the process is very easy and straightforward, we promised that we would pre-install these, and we will stand by that.

Any backers who have ordered USB-C Dopplers will have their units pre-installed with USB-C.

We also would like to take this opportunity as another reminder that if you want USB-C on your Doppler, please follow the instructions in this video and upgrade your pledge to USB-C in your Backerkit and we will pre-install it for you! (Please refer to this update on how to do this). For those that want to upgrade to USB-C in the future, you will be able to do so with minimal effort thanks to this kit.

Color matching

Finally, we would like to discuss a small tweak we are working on with colors. We have, effectively, three different types of LED’s on the Doppler which all make up the 136 lights. There are lights under the silicone in the top buttons area, as well as two types of lights behind the main window. We have spent some time tuning these 3 light sources and matching colors to make them all as uniform as possible. There is still some slight variance in the lights and materials used on the individual Dopplers but we think the colors match much better now.

Beta update

We also wanted to give a quick update to the Beta backers. We have been hard at work on the build for Amazon certification and once that build has been completed and verified we will push it to you. Thanks again for your help and feedback with the beta program. We do have a couple more beta units if you’d like to change your order to a Beta Doppler, please send us an email at [email protected]

Thanks again for all your support and please let us know if you have any questions in the comments below.

Tuning, testing, and bug fixing before certification
over 4 years ago – Sat, Jul 18, 2020 at 10:13:55 AM

Hi Doppler backers,

We have been hard at work the last couple of weeks fixing bugs and getting the Doppler prepared for final certification. In this update, we will discuss the progress on the AEC issue, Android Beta bugs we have found, and how we are gearing up to ship your Doppler. Once we get past the certification hurdle, we can proceed to the step we have all been waiting for: shipping! So what’s the latest on certification? Read on…

AEC issues

In the last update we discussed the “self-triggering issue” where Alexa will hear herself say “Alexa”. We had to fix this issue before we proceed to certification and while things aren’t entirely fixed, they are working much better! After discussing the issue with our suppliers we were given some new DSP firmware which reduced it by almost 90%. We also hired some acoustic experts to help us tune our DSP firmware to further reduce and hopefully eliminate this issue while also getting the best possible performance out of the microphones. For example, if we lower the sensitivity of the microphones the self-triggering issue with Alexa hearing herself will be reduced but she will also have a more difficult time hearing you when you are further away from the device. Now it’s a balancing act of different settings and we have to find the sweet spot. Our acoustic experts are currently working on the tuning and will then run all Alexa pre-certification tests again to make sure everything is in line. We have done all of these pre-tests before, but we need to test again with the tuned DSP firmware! Once we finish all our pre-testing, the certification process can start!

We took off the sound with this video to prevent any accidental Alexa triggers with your current Alexa devices.

The Doppler is currently working like this most of the time! 

Music services

Another exciting piece of news is we have enabled more music service providers which all work on the Doppler: Amazon Music, Audible, Deezer, iHeartRadio, Pandora, SiriusXM, and TuneIn! All you’ll need to do is ask Alexa on the Doppler to play music on your favorite service and it will work right away (after you sign in). Beta users, all of these services are now live on your devices, enjoy the music! There are two services missing from this list, Apple Music and Spotify. Apple Music is currently not supported on third-party Alexa devices and we are working on Spotify support.

Sorry for the bad sound quality!

Android Beta

Since our last update, we have shipped all Android Beta backers’ units. These units were the last in the Beta program to go out and we have now officially shipped all Beta Dopplers! We had a show-stopping bug that we couldn’t have found without our Beta backers. The issue was around Alexa -- we had a number of Beta testers who couldn’t successfully set up Alexa on their units. Luckily this is why we do the Beta tests and we have fixed that and a couple of smaller issues with an Android app update. Post-update, every Beta tester we have heard from has been able to get their Beta unit connected to Wifi and Alexa! There are still some Bluetooth connection bugs we need to figure out and we are actively working on that with our app team.

We are working on finalizing a new Beta software build over the next week or so that will include some new features and the improved (but not fully tuned) version of the DSP firmware. When the new release is published, a full changelog will be on our updates page here: https://manual.sandmandoppler.com/release-notes/

Want your Doppler a little earlier? All Beta backers have received their Beta Dopplers, and we still have some units remaining. So if you’d like a Beta Doppler instead of your production unit, please send us an email at [email protected] and we can discuss switching your unit to a Beta version. We only have about 20 Beta units left so email quickly!

Shipping Improvements

During the last couple of weeks, we also have been continuing to refine our shipping process so once we get Alexa certification we can ship Dopplers as fast as possible. Under normal circumstances, this would involve bringing on and training additional staff members to ship production units as fast as possible. The current county restrictions due to COVID-19 have made this very hard due to the size of our warehouse and social distance requirements. In order to get your Dopplers shipped ASAP, we have been working on some improvements to speed up this process. We previously shared our flashing cart that we built… well, now we have an army of flashing carts!

These flashing carts will allow us to reflash 20 Dopplers at once with a single power cord on wheels! We plan on using these carts to improve our efficiency by simultaneously batching and reflashing as many Dopplers as possible. We currently have over 1,500 preorders and we estimate it will take us over 3 months to ship all the pre-orders. We aren’t happy with this so we have also created a new version of our Doppler Diagnostic Application (learn more about the previous version of DDA here). This new version of the application automates a lot of the processes that were previously done manually.

We will be running this new version of DDA before shipping the products so we can catch any problems the factory might have missed. This version of DDA will also streamline the QA (quality assurance) process.

We also have invested in a new automated tape dispenser! This new packaging tape is called gummed tape (also known as paper tape or kraft tape) and is most commonly seen on boxes from companies like Amazon. Gummed tape is much faster and easier to apply, permanently bonds to the cardboard, is more recyclable, and can be customized. We have designed our gummed tape with the Sandman brand and color and we love the way it looks.

Thanks to all these efficiency improvements we think we can increase our throughput of Dopplers and ship out all production units much more quickly.

Finally, we just wanted to say that we are aware that we have reached a frustrating milestone... three years since this product launched without shipping. While we aren’t pleased about this, we are very proud of how we have persevered past numerous hurdles and haven’t stopped when things got really tough, especially in the last few months.

As always thanks for your patience!

iOS app is live, Android beta is go!
over 4 years ago – Fri, Jun 19, 2020 at 11:15:03 PM

Doppler supporters,

We have reached some big milestones since our last update! 

First off, our app is now live in the iOS App store!

We aren’t 100% happy with the app, but we are tracking all the bugs we can find and are working to fix them as soon as we can. We are also far from finished with the app, so many new features will be coming down the pipeline.

If you’d like to install the app before you receive your Doppler, you can! However, there isn’t much you can do with the app without a Doppler, so we recommend waiting until you receive yours (more on that later).

Also, a note to our Beta backers, the Beta version of the Sandman app that was running in test flight has expired. iOS Beta backers please migrate over to the version in the app store and let us know if you have any issues. 

Android Beta

We are also happy to announce that the Beta version of the Android app is finished and we will be launching the Android Beta once we get approval from the Google Play store (hopefully in the next couple days) and do some final testing. We have emailed all remaining Beta backers, so please check your email for more details. 

AEC issue

While we wait for the feedback from our Android Beta testers, we are working on an acoustic issue with the Doppler that we discovered over the last couple of weeks. We have only had 2 of our 60+ Beta testers report the issue, but unfortunately, it’s a requirement from Amazon so we have to fix it before shipping units to you all.

The issue revolves around acoustic echo cancellation (AEC) which we talked about in previous updates and is manifesting itself in an interesting way. Alexa currently hears herself whenever she says her own name. So if you ask, “Alexa, who are you?” she responds, “I’m Alexa”. When the word “Alexa” comes out of the Doppler speakers the wake word engine in the Doppler hears this and starts listening for the rest of the command, which of course doesn’t come. This usually ends up in a loop, where Alexa says her name, she hears it and starts listening for nothing, and the process repeats itself. This is an issue with the AEC and the wake word engine not working correctly with Alexa. The AEC on our device is working very well in some situations since in most cases the Doppler can hear the wake word, Alexa, even when very loud music is playing from the Doppler, but it’s not working for the wake word Alexa.

We have contacted both the supplier of the AEC solution, which is built into the DSP (digital signal processor) chips we have on our boards as well as the software-based wake word engine. Both of these suppliers are Amazon-approved solutions, but still aren’t passing Amazon certification. To make matters worse and more frustrating, the suppliers are both pointing fingers at each other as the cause of the issue since things are working very well for everything else other than this one issue with Alexa hearing herself say, Alexa.

We are currently in communication with Amazon and both suppliers, along with a couple of outside consultants and Amazon-approved Alexa experts to try and come up with a fix for this issue. We have a couple of workarounds that we are testing to see if they work, but until we fix this, we can’t go to Amazon certification.

Software updates

Along with this AEC issue, our development team has also been working on many other software features for the Doppler. We have created a very simple release notes page on our manual which is where we will post any and all software updates we have been working on. The page is located here: http://manual.sandmandoppler.com/release-notes/

Amazon keeps releasing new versions of the Alexa SDK, which we are trying to stay up to date on. The newest version (at the time of this writing) is 1.19.1 and includes a feature called local ducking. With local ducking, when you have music playing and you say the word Alexa she will “duck” the volume of music and lower it while she responds. Previously the music would stop and start rather than just “duck”.

We added a new animation to show the Doppler is booting. You should only see this animation when you power cycle the Doppler, or when it’s going through an over the air software update. We are calling this the KITT animation, but some Beta backers have described it as a Cylon animation. Whether you’re on team Cylon or team KITT, we love the way it looks!

A feature was added to sync the timezone of Alexa and the Doppler. Whenever you set the timezone of the Doppler in our app, it also sets the timezone of Alexa. Previously they weren’t synced. These are the types of bugs we are grateful to have Beta backers for. Thanks all!

Based on the feedback of the Beta backers we adjusted the volume scaling as some thought it was still too loud at the lowest volume. We plan on tweaking this further later.

Another big thing we have been working on is how the alarm button and alarm light function with recurring alarms. Here is how the new alarm feature works:

There are three different types of alarms, each with a different color. Red is the system alarm, which is controlled by the buttons on the Doppler. Green is app alarms that are set by the app. Blue is Alexa alarms which are set by your Alexa using your voice or the Alexa app. We plan on adding the functionality to customize the alarm color soon in the app soon as well, but back to the alarm button.

The alarm button and alarm light (top left of the display) on the Doppler will show the color of the “next up” alarm based on the type of alarm. These indicators will only show up for armed alarms and won’t turn on if the alarm is switched off in the app.

Each time you press the alarm button it only turns off the alarm that is “next up”.

When you have no alarms coming up, the alarm lights will turn off. Please note, Alexa alarms don’t stay on the app like app and system alarms after they have gone off. This is a limitation of the current Alexa SDK and we have requested they change this in the future.

If you have a recurring alarm active, the Doppler will wait an hour to turn on the next occurrence of that alarm. So when you go to bed, your Doppler will show that your morning alarm is armed and will go off at the proper time.

There are many advantages to this new alarm button behavior, but we look forward to your comments and thoughts about what we can change or improve in the future. We are planning on having the alarm button be customizable in the future.

Along with working on software features, we have also been working on the main complaint of the Beta program, which is Bluetooth connection issues. In general, things are working much better than before, but we still haven’t totally solved that issue. We will do our best to keep hammering away at it to assure the best user experience possible!

When is my Doppler coming?

As we mentioned in the last update, things are still changing with regards to our county’s shelter in place rules and this latest AEC issue is preventing us from going to certification. But once certification happens and we can return to our office, we will begin the reflash process and start getting your Dopplers out the door. Since rules and regulations are changing and we aren’t sure how long things will take with this AEC issue we don’t have any accurate time estimates. We know this isn’t what you want to hear, but we are doing everything we can to get your Dopplers squared away and shipped, and we thank you for the continued support!

The Dopplers have arrived!
over 4 years ago – Fri, May 08, 2020 at 11:09:39 AM

Hi loyal backers,

We hope you are all safe and sane! Ok, enough of the pleasantries, we have some amazing news we need to share...

The Dopplers have arrived in our warehouse!!

So what do we still have to do before you get your Dopplers?

The next step is the Android app beta. The remaining Beta Doppler units should go out in the next couple of weeks and we plan on this beta period lasting no more than a month. While the Android beta testers are testing, we will be working on the bugs the iOS beta testers have found in preparation for launch.

Once we go to Android beta testing, we will also submit the Doppler to Amazon for certification of Alexa. At this point, we have been working closely with a couple of different teams at Amazon for years, all leading up to a certification called AVS (Alexa Voice Service) certification. Since Amazon wants to ensure that all products using Alexa works as seamlessly as possible, they require final products along with both the Android and iOS apps to make sure that both apps are capable of setting up Alexa properly while following all of their guidelines before selling units. We have done a ton of self- and pre-testing and we are hoping that everything will pass with minimal changes required.

Once we have received our AVS Certification, we will begin by reflashing these Dopplers in our warehouse. While we are flashing these units, we will also do a final inspection to hopefully catch any lemons that our factory QA team might have missed. This process will likely take a while due to the shelter in place order our county is currently under. We aren’t going to give any timelines at this point since so much is changing daily.

Once we have Dopplers that have been flashed to the latest software updates and gone through a final inspection, we will begin shipping according to the following schedule:

1. Domestic Early-Bird customers
   
2. Other domestic customers
   
3. International customers
   

We have quite a few orders to get through so please keep an eye out for emails from backerkit a couple of days before we ship your order confirming your address and then a tracking number once it’s been shipped!

Getting the units into our warehouse brings us one step closer to getting your Doppler delivered, and we want that day to come ASAP!

As always feel free to reach out if you ever have any questions.

The Betas are in the wild!
over 4 years ago – Fri, Mar 27, 2020 at 01:39:05 AM

Kickstarter backers,

First off we want to start with hoping that all of our amazing supporters are healthy and safe as that is the most important thing in crazy times like this. We also wanted to bring back the GIFs from our previous updates to help lighten the mood. Don’t worry most of the news in the update is VERY positive.

It’s been a weird and strange couple of weeks for us over here at PAI headquarters since our last update. In this update, we will discuss where in the world your Doppler is, how the Beta is going, and how the Virus is affecting us. Make sure you read the entire update, we have some free stuff for you!

COVID-19 and the Doppler

There is a high likelihood that wherever you are reading this from is experiencing effects from the current COVID-19 pandemic. While we have been dealing with some of its effects for a couple of months due to our close relationship with our factories in China, now that the virus has reached the US, things have changed considerably. We don’t want to spend too much time discussing unpleasant things, but we do have to share some quick updates.

On March 16th Santa Clara county announced a “Shelter in Place” order which forced everyone at the office to head to their respective houses and do their best to work from home for the safety of the community as a whole. We made sure that our team has Dopplers to work with at home and we are lucky that the Doppler is mostly in a software phase at the moment. If this had happened earlier in the development process, it would have been much more difficult to continue working efficiently.

Production run update

One of the things we aren’t able to do under this shelter in place order is ship out orders from our warehouse. This is obviously not ideal but it does lead us to some good, nay AMAZING news. After more red tape and bureaucracy than we ever thought possible, the first production Dopplers are in a container and loaded on a ship to PAI headquarters!

This process took so much longer than we had ever imagined, but thankfully your Doppler is finally onto the next step before reaching your nightstand.

Once the ship arrives into the port of Oakland (it’s currently scheduled to arrive on the 11th of April) our container will undergo customs clearance and then onto our office! We aren’t sure how the current state of affairs will affect the travel time and customs clearance process, but we have been told to prepare for delays as so much in the world is in flux.

Once these Dopplers finally arrive in our warehouse, we will need to re-flash the units and do a final quality check before sending them out to you. We don’t know if the shelter in place order will still be in effect when we receive the Dopplers, so we similarly don’t know if we will be able to get to work on them right when they arrive. Rest assured, as soon as it’s safe to resume normal work we will begin the flashing, QA and shipping process on your Doppler!

Beta testing

Before the pandemic really hit us, we were able to get out quite a few Beta Dopplers to our Beta backers (Over 70 units). As discussed previously the units sent were only sent to backers with iOS devices only as the iOS app is currently in a better spot than the Android version (more on this later). Finally being able to ship some Dopplers, even just Beta units, has been an awesome feeling. Thanks to all the Beta backers who have provided feedback so far! In general, the feedback has been very positive and the Beta program has uncovered some software and app issues that we wouldn’t have found by ourselves.

Here are some pictures of the Dopplers sent to us by the Beta backers:

For the sake of transparency, we have had 2 Beta Dopplers that had major issues. The first one is on its way back to us for debugging as the unit seems to have a problem playing any sort of sound. The second unit had a bad external power brick and was an easy enough fix.

Most of the bugs that our testers have reported are around timezones, Wifi, and Bluetooth. Although thanks to our backer's help we have found some new issues as well as ways to improve our app and Alexa. The good news is that the hardware appears to be working well and everyone is happy with the look and feel of the Doppler. We are working on these software issues and when we fix them we will push new updates to both the app and the Doppler unit over the air.

We still are working on the Android app and are hoping to get something finished in the next week or two. Our app developer, Zemingo is based in New York and Tel Aviv which are both in a similar lockdown situation as we are out here in California and are working through it, but not as efficiently as anyone would like. Once we have an app that we are happy with and it’s safe to ship the remaining Beta units, we will do so.

We also wanted to thank all the Beta backers for their feedback (positive or negative) and kind words. After working on this project for a long time, hearing some  of the very positive feedback has been amazing:

“I love my Doppler!”

‘Auto-dimming is sick!’

“Good build quality.  The heft of the unit is nice. The plastic used for the primary frame of the unit is great.”

“This is a great looking clock. The display is huge!”

“It looks beautiful.”

“I think it is great”

“Fit and finish feels good, premium. No gaps or wonkiness in assembly, feels solid and doesn’t move on the desk/nightstand. I have an 18-month old who loves to grab the 5” echo show on my nightstand and this is exponentially more ‘stuck’ to the surface”

“It's a great Alexa-enabled alarm clock”

Manual is live

We have also been using our Beta backers to test out the online manual we have for the Doppler. This manual is now live at: manual.sandmandoppler.com  - if anything seems unclear or you notice an error, please let us know! We also have been hard at work on a list of FAQs that are now live here these will be constantly updated when we add new features and such. As always if you have any questions or comments please feel free to send an email to us at [email protected]

Amazon certification

One more wrinkle for the Doppler is around Alexa certification. Amazon requires all devices that utilize their AVS (Alexa Voice Service) to pass strict security and quality certifications before being able to be sold.

We have already passed the acoustic testing from a third-party lab as noted in the previous update, but Amazon will need to do this testing again themselves along with some other functional testing. We also need to send a Doppler to a third-party security testing lab to make sure we pass Amazon’s strict security testing as well. The third-party testing lab is located in Taiwan and is still open and functioning normally, but the Amazon labs are located here in the States and are all shut down at the moment like we are. I’m working with our representatives at Amazon to figure out how to get the unit certified as quickly as possible, but this could cause another delay.

Free stuff?!?

To redeem this please go into your Backerkit and navigate to your add-ons section. In the add ons section you’ll see a free charging cable option and in there you can select what type of cable, color, or even a wireless charger!

You can look up your Backerkit link here: https://sandman-doppler-the-worlds-best-alarm-clock.backerkit.com/

Here is a quick video showing the process of adding an add-on in Backerkit:

If you’re having issues with Backerkit, please let us know what kind of free cable or wireless charger you’d like and we will add it to your account. The best way to get a hold of us is by sending an email to [email protected]

Hopefully, this update helped brighten your day during these difficult times. Very soon you’ll be able to share these difficult times with your Doppler!

Stay safe and healthy
