BRAGI UPDATE - on track, on track and gems overview.

145 likes

Dear Backer,

in our last update we told you that The Dash works. And it still does. 

Major part of our work has been focused at increasing the stability of The Dash to ensure that it works really well. 

Audio performance

We have speakers and microphones embedded in The Dash. Those are protected from water ingress by membranes. The membrane on the ambient microphone works great, while the membrane in front of the speaker induce distortion at low frequencies.

By applying different adhesive and optimizing membrane structure we expect to remove the distortion in the next few weeks.

Mechanics

The last puzzle parts of the mechanical structure have come together. All injection mould tools are done except for the injection mould tool for the charging area on The Dash. It needed further improvement to decrease assembly time and reduce production risks towards waterproofing. It is noncritical to the current plan.

BRAGI Operating System & Software

The Dash is a evolving platform that is capable of improving though time through software updates. All future operating system upgrades for The Dash will be free of charge for you. 

We have 3 major software releases planned. Blacklight (V1.0), Essence (V2.0) and Promise (V3.0). 

Blacklight has all features needed to be able to production test and user experience test The Dash.

Essence adds additional features and Bluetooth Low Energy support. We rely on a final firmware upgrade from a supplier promised for ultimo July to enable us to qualify the Essence software for final production.

Promise adds more advanced sensor features like airtime, cadence, laps and others.

Blacklight RC (release candidate V0.9) should be finished this Friday and will be tested until being used for our production run scheduled for July 13th through July 24th. 

Essence RC (V1.9) is planned for the 27th of July and will go onto all the developer kits. Essence (V2.0) is planned for the pilot production planned from the 17th to 28th of August.

Promise (V3.0) is planned for late September/early October update through the Bragi APP. After Promise (V3.0) you should expect bimonthly software updates that will improve the user experience, increase sensor precision and correct issues only found within large numbers of devices.

BRAGI App

Work is progressing according to time-plan. The App should be in the respective app stores by end of August.

A nice feature is the integrated help function in The App. Martin shows you how that works inside the iOS app. So if you have ideas, need help or have specific challenges, we will be able to help you directly inside the BRAGI App when you have received your Dash.

Things that aren't optimal

In order to make an ultra low power The Dash, we had to make some concessions. 

Lower USB transfer speeds require less power hungry chips inside The Dash.

Our choice was significantly longer battery life vs. faster USB data transfer. Battery life won.

It will take approximately 4-6 seconds to transfer a mp3 song to The Dash. Filling all the available space on The Dash with music would thus take an estimated 4000-6000 seconds (67-100 minutes). We hope that is acceptable to you with the obvious benefits in mind.

Hidden gems that make The Dash even better

If you haven't been following conversation in the comments, you wouldn't know that The Dash will do more than promised in our Kickstarter campaign. Just to sum up the most important gems:

Battery life up with 33% towards Kickstarter promise

Improved with better speakers and acoustic performance (balanced armature speakers)

Improved with higher performance ear bone microphone for speech 

The Case will be able to recharge The Dash up to 8 times at 20 deg C (In total providing 24 hours playtime without access to USB power).

Awesome case with aluminium slider

Magnetic connector for simple and convenient placement of The Dash in The Case.

Functions that are enabled in future software releases:

Added a 3 axis gyroscope sensor that can measure relative rotations (activated in Promise)

Added a 3 axis compass (magnetometer) tell absolute direction you are looking (activated in Promise)

Two independent bluetooth systems. One system is connected to your phone/tablet/laptop as a slave. The other bluetooth system enables other devices to connect to The Dash as the master. That enables The Dash to control or receive data from other sensors, locks, watches, IoT devices, remote controls etc. This functionality is expected towards a December/January release time.

An this is just the start of an exciting journey.

Refunds

Backers have no right to a refund from Kickstarter projects, but we felt that anyone should have the right to step back. Also due to the unforeseen challenges we encountered.

Your support has been amazing, and very few has chosen to get a refund. On this Friday we have to order all components needed to build The Dash for you. We hope that you understand that we can't do any more refunds for products we have already bought parts for. 

As of today we will not provide any refunds anymore. We have kept our timeline since early April, and are looking forward to provide you with The Dash.

Competition on name

We had a small competition on our Facebook page to give the magnetic charging interface inside The Case a name.

We chose MagSnap. Short, precise and similar to the noise made by The Dash when placed in The Case. 

Congratulations to Alasdair Grant who was the first one to come up with the name. What do you think?

BRAGI UPDATE - years of development, moments of utter joy and finishing what we started

436 likes

Dear Backer,

bear with me if this update is slightly emotional. 

I quit my job 2,5 years ago, and it has been a wild and inspiring journey to achieve something that everyone told me was impossible. 

BRAGI and I wanted to make entertaining discrete assistants. Not just assisting while doing sports, but also enabling people that have been impacted with disability, to prevent diseases, to improve safety and ability of people at work and many others areas. And all of that with the highest regard for privacy. 

Because we are convinced that we are working on a project that can assist millions of people we needed and wanted to succeed. We have done everything within our ability to avoid failing. 

I must admit that we literally have been days away from failing. Our deep desire to succeed helped us through those challenging times. 

That is why I'm incredibly proud to announce that we have solved all major issues that could keep us from delivering The Dash to you. 

Wireless performance

Major cause of delay was caused by challenges with wireless performance between the right and left Dash. It might sound like a trivial thing to solve, but it definitely hasn't been trivial. We have spent millions of € to solve that problem.

Our previous solution should and could have worked, but in certain use cases it would have been challenging with frequent dropouts or stereo audio not working at all.

We initiated implementation of plan C as communicated a few updates back. We actually made sure that we could implement plan C back in October 2014.

It works

Plan C uses magnetic induction rather than radio waves for communication between right and left Dash. The Dash is still capable of connecting to a smart phone or computer via Bluetooth.

Each headphone creates a magnetic bubble of approximately 25cm. It is immune from wireless interference and virtually secure from eavesdropping. It is absolutely safe from a health perspective and much better than using bluetooth between the ears (we live in a huge magnetic field created by our dear earth).

The link is incredibly stable and works in virtually any condition except within very strong magnetic fields (that are very rare).

The Dash will provide stable stereo playback even if the user has long and wet hair, is wearing a helmet for skiing or biking and in other challenging conditions. It will even work while swimming (down to 1m depth due to water proofing). We think that is AWESOME!

The energy consumption has been reduced as well, so expect an increase in battery life of 30-40%. That results in improvement from 3 hours promised to 4 hours or more pending on sensor activity.

Testing

The technical challenges that could prevent us from making The Dash have all been solved unless there is something we have missed.

In next 2,5 months we are going to test, test and test The Dash to prevent any critical flaws when the product is delivered. We have an automatic hardware and software test system that simulates the use of The Dash with hundreds of interactions every second (rather than the one interaction every few seconds from a human) to find issues.

Our BRAGI app also features a feedback option, where users can feedback on issues directly to our developers (idea from a backer, thank you).

The Dash will go through certifications (FCC, UL, CE and a few others). These certifications could cause that we need to modify the product, but we do currently not think it is needed.

Production

Our team and our manufacturing partner have been developing fixtures and jigs as well as testing procedures.

This might sound trivial, but the task is quite massive. We need to manufacture and test thousands of products every single day and need automated equipment to do so.

An ultrasonic welding machine has been bought to weld the housing parts together, and fixtures to hold The Dash while welding has been made.

BRAGI UPDATE - Alpha5 & back to China, backer day, on track!

170 likes

Dear Backer,

in our last update we reported on good progress with Alpha5 prototypes. Progress is still on target to what we communicated previously.

Alpha 5 & back to China

the Alpha 5 printed circuit boards are expected to start being populated with electronics on Monday. Right now, Eric, Vlad, Arne and Daniel are on their way to China to our contract manufacturer.

Eric and Vlad are going to work on factory hardware and software testing as well as bringing up the Alpha 5 products.

Factory testing is done to ensure that the processes are set up in due time to ensure smooth product introduction to the factory.

We have been testing the current electronics schematic in our offices on our development board, and all looked good.

From a mechanical point of view, Alpha 5 will be built from first out of tool production materials. We have made all plastic and metal injection (MIM) tools necessary for The Dash, and we are looking forward to see the first devices that look like finished product.

Alpha 4 where some parts are rapid prototyped
Alpha 4 where some parts are rapid prototyped

When we receive Alpha 5 back in Munich, we need to do thorough electronics, software, acoustics, algorithm and co-existance tests to ensure a solid product.

If Alpha 5 prooves to be solid, we could go into production of beta products in mid July (and even have some time to spare if another fine tune alpha 6 round if needed).

Backer day

Wednesday was a great day. Torgeir and Jeffrey came in from Bergen, Norway and Houston, USA/(Texas). On top of that 15 others joined in. Edy from Vienna had made a BRAGI cake all night, took the 8AM train, arrived in Munich 3pm, stayed until 9pm and took the night train back to Vienna arriving thursday morning. Amazing commitment!

They all obviously just tested a right Dash, since we have to wait for Alpha 5 to have the solid link between right and left. 

A few comments from our backers (copy pasted from comments section):

Roland Klingesberger: 

@for all I was there too on Wednesday. For me it was an interesting and very impressive visit. They spend about 4 hours with us. They explained how everything started, some background about the initial ideas and what they think and plan in the greater view for the future. 

 I was very surprised that they were very open and explained things about the long term view and the experience they made. For me everything is very promising and I' m confident we'll get a great product in September. I can tell that they work very hard and with all three heartblood to get the thing done. 

@for Bragi Thank's for the the afternoon and evening and it was awesome.

Fabian Göttel: 

I was there too. I was really surprised and amazed how much time every single bragi guy took for us. After nikolay told us how bragi started we continued our tour, splitting up and had intensive talks with the hard working guys. 

My personal highlight was the moment as I experienced the dash. First impression: sound quality is really good and the fit is even better. So I even got more excited and cant await to get my pair of the dash! 

Tldr: Amazing!

John Good:

@all I was there yesterday. We had to sign kind of an NDA and to switch off our phones. But you will get the video from Bragi anyway. 

 What I can say is that it was a really awsome, interesting afternoon and evening. They were receiving us very heartly and speaking very openly about their experiences during development of the product. We got the feeling that everybody at Bragi is working with blood, sweat and tears to bring the Dash to market. And it will be awsome. We were able to test the sound quality and the fit and it looks very promising. The new tech for left device to right device communication is awsome and will make the product even better. 

What impressed me as well is the long term vision Bragi has for the product. The evening closed with a beer at a bar. 

 @Bragi Thank you again for this great opportunity.

We will prepare a video for our next update with some recorded comments too.

BRAGI UPDATE - status on wireless, bits and pieces, testing - oh yeah, timeline

202 likes

Dear Backer,

in our last update we informed you on the challenge with wireless performance that resulted in a delay.

Wireless performance and Plan C!

As explained in the last update, we had challenges in the ear to ear performance through a wireless bluetooth link. We do still not have a timeline on how to solve that challenge from our supplier, so we have to move full speed ahead on the alternative solution (plan C).

Plan C impact

In order for plan C to work, we had to add an additional antenna into our design. So we have one antenna receiving music and data from a phone, and the other antenna system to transmit between the ears. We designed several different antenna types our system, and found one that works very well from an antenna performance perspective inside our system.

Josef had to modify the internal mechanics to accommodate space for the additional antenna, but luckily we had already left space for it. When we finalised the mechanics back in October last year, we knew, that there was a small risk for this to happen. Long live provisioning for alternatives!!! So only minor modifications were needed.

Our electronics team (Andreas, Karin, Vlad, Eric, Chris and Lisa) have prototyped, created a new schematic (plan of how electronics "talk" with each other"), designed a new layout (how the physical electric traces are placed) for the right and left dash (they are different), made CAM review (computer aided manufacturing) within the last 3 weeks. 

While getting all of that out of the door for our alpha 5 prototype run, they managed to create a new development board with the required modifications too. The development boards were received earlier this week. (Hats of to our supplier!)

Usually we'd take about 6 weeks to do 2 different designs (not even counting the development board in), and I don't even dare to ask them how much evening and weekend time has been spent to pull this one off. But they look tired. Huge applause from me to the team.

Alpha 5 prototypes

The production files for our alpha 5 form factor prototypes have been delivered to our supplier , and we should receive the printed circuit boards in 3 weeks. It will take another week to place the electronics onto the form factor boards. So we should receive the new alpha 5 electronics on the 26th of May for electronic and software bring-up (ensuring that everything works as expected).

This is on time according to the time-plan for delivery starting early September.

Bits

The software is an essential part of The Dash. Needless to say that we've been thrown back, because we had to change essential data communication paths and protocols. The software team had to reroute all data communication between right and left to a different type of connection, and ensure that we aren't loosing data (audio and sensor information) in the process. They should complete the transition by the end of June.

Except for the setback of changing the architecture of the electronics, we are on track having our launch software ready for testing and debugging by mid July.

Pieces

After implementing the modifications needed for the additional antenna, we needed to modify some tools that we already had made, as well as ordering new ones. 

After realising that we had to postpone the delivery due to other reasons, we decided to improve the charging interface between The Dash and The Charger. We already had injection moulding tools made for this, but we saw some challenges in long term mechanical stability that we wanted to correct. This has no impact on delivery of The Dash.

Marius, Josef and Arne have made a beautiful piece of engineering. Enjoy the video of Charger/Dash interaction. The LED's indicate if all pins connect.

Testing

An essential part of delivering a solid product is testing.

We are currently using 8 Rasperry Pi's (small computers) with a custom test software infrastructure. Every time a developer publishes code, a The Dash pair will automatically get a firmware update with the updated code and start a complete test to see if the code works, as well if it degrades previous code.

We are scaling that to 24 pairs of The Dash (48 units) running permanent tests in our climate chamber. 

The climate chamber is shifting temperature from -10C to +50C while also changing humidity. With this, we can do accelerated testing, simulating an entire lifespan in a few weeks/months (depending on what we are testing).

BRAGI UPDATE - status on wireless, supply, timeline and Open House @ BRAGI

Dear Backer,

we were about to receive our Alpha4 prototype electronics shortly after the last update, where the most important issue was to test and optimise wireless performance. No Aprils fool jokes in this update!

Video is 10m long. Everything I say is written below too.

 project video thumbnail

Why is wireless performance so important?

This is a hugely simplified explanation of the situation to give a high level, transparent understanding.

The right and left Dash "speak" to each other by sending music and data wirelessly through a bluetooth wireless link. The wireless signal can't go through the head, so the bluetooth antennas of The Dash are designed to focus the wireless signals behind the head. We have spent significant time and effort to design the antennas. "Standard" antenna design wouldn't even remotely be sufficient. 

Testing wireless radio performance in anechoic chamber (reflection reduced room)
Testing wireless radio performance in anechoic chamber (reflection reduced room)

To design a great antenna, extensive computer simulations and laboratory measurements are made. The antennas are designed to resonate and perform in perfect harmony with the bluetooth chip and the system it is used with. Important specifications of the bluetooth chip are how loud it can "speak" and how well it can "hear". From alpha3 testing back in January, the "speak" performance was great. The "hear" performance wasn't good enough to enable a solid link (a lot of noise in the system). We thought it was because of noise originating from the dash electronics itself, so we spent a lot of effort reducing the noise emitting from the electronics. All those changes were made to Alpha4 electronics prototype that went into production mid January to be received mid March. When we started testing the wireless performance 2 1/2 weeks ago and the "speak" performance was stellar. The "hear" performance had improved, but was still not good enough. We started deep investigative testing of the antenna with an artificial signal generator "simulating" an ideal bluetooth chip in huge detail, and got results showing that something isn't working as expected from our bluetooth chip supplier. 

What is the impact?

In a calm wireless environment (e.g. not a lot of wifi around) the product would work well. As soon as there is more than a few wireless networks, wireless link between the headphones would break up. In any environment where there is a lot of radiated noise, The Dash wouldn't work well.

The sensitivity to noise is caused by the size of our device combined with an issue of the bluetooth chip not performing to specifications provided by the supplier. The manufacturer of our bluetooth chip has provided significant resources to fix the problem, yet not being able to provide a timeline or guidance for a technical fix.

"xxxx" <- place a not very nice word in the x spaces.

This is more than incredibly frustrating. 

We always had 2 alternatives in our backhand (plan C & D) to mitigate risk. While we will continue to pursue a solution with the current bluetooth chip supplier and antenna (Plan A) and to improve the antenna even further (Plan B), a solution is out of our hands. 

We expect 9-12 weeks for an additional prototype production, software and hardware testing after the bluetooth issue has been resolved. We have weekly jour-fix with our supplier to proactively address the issue. We have no influence on solving the issue, and we have received no indication by when it will be solved by our supplier. 

What are the implications of Plan C

As written in the last update, we are committed, capable and have a technological solution (plan C) for finishing The Dash to the specifications presented here on Kickstarter. We will assign significant resources to pursue plan C, to mitigate risk if plan A fails. If plan A evidently fails, we will divert all resources to plan C.

Plan C a significant technology pivot that will cause a delay. 

A significant benefit would be additional battery life to a theoretical 4,5-5 hours while playing back from The Dash embedded music storage. Major disadvantage is only on BRAGI's side. The solution is considerably more expensive to build than plan A.

Every single component has been cost negotiated with suppliers, and the suppliers are selected and awarded this and next week. The product will be produced in China by a contract manufacturer that we have worked with for over a decade. 

Design verification of injection moulds as well as design for manufacturing steps with suppliers
Design verification of injection moulds as well as design for manufacturing steps with suppliers

Everything is set up to push the button. Trust me, I've been dreaming about that day for the last 2 1/2 years!

Injection mould tools

Most of the tools already exist and have been reviewed. We mainly need a few modifications to the existing tools and a few new tools. We are very happy about progress.

Testing of The Dash

Every time a developer releases code to our system, that code has to be tested against our user experience criteria and towards automated tests qualifying that code.

David, Torsten and Toby have been significantly expanding on the capabilities of our testing setup. By the time that we receive Alpha5 prototypes, we will be able to have 50 pairs of The Dash in our test rig, that can be assigned to parallel test routines.

We should be receiving our environmental test chamber (cold/heat and humidity) next week, to perform accelerated lifetime tests on the electronics.

The test setup is done to ensure as few bugs and failures as possible when we launch The Dash. 

BRAGI App

We showed a clickable version of our app a few updates ago. We used the feedback from you to further improve the usability. The app development team (Martin, Luigi, Michi, Arne, Rene and Christian) are working on iOS, Android and Windows Phone versions.

Open house day @ BRAGI

40 people go to work every day in our office in Munich. We all think that we are on to something special, and we would like to share that feeling with the ones that made it possible for us. 

I'd like to invite our backers to our office in Munich, Germany on the 13th of May at 4pm (15 people maximum due to fire regulations) for a tour and a beverage at the local bar. We will not prepare any special demo's (delivery of final product above everything), just give you an overview of our work, see The Dash in real life and be able to chat with our developers.

We will make a small video to be sent as an update after the open house day to share a bit of the experience.

To attend open house day, write a mail to openhouse@bragi.com

Do please only write if you really can attend. We will randomly pick the 15 attendees by 13th of April.

2 incredibly lucky backers

We will randomly pick 2 people from the BRAGI backers who comment "I'd like to meet BRAGI" in the comments of THIS update. 

BRAGI will buy a (return) economy flight ticket and 2 overnight stays in a local hotel for the event on the 13th of May (all other costs are not covered by BRAGI). "I'd like to meet BRAGI" has to be written into the comments and be visible to BRAGI by 4.00pm CET 13th of April 2015 to be acknowledged.

We will announce the winners in the comment section and contact them to arrange flights.

Best regards,

BRAGI TEAM and Nikolaj

BTW, the few who requested a refund have been swiftly processed throughout the last months.
