Dear Wynd Community,

We loved reading your positive comments on our last update, and we’re always grateful for how willing you are to share feedback (and encouragement!) with us. The team has been hard at work for the past few weeks and we wanted to provide the latest update on our progress!

Manufacturing Progress

We’ve come a long way in the manufacturing process, including, finalizing product design and prototypes, initiating tooling and injection molding, sourcing components, and adding finishing touches to UX/UI on the app.

Wynd Home Purifier Progress

The Wynd Home Purifier is progressing well, we already made a trial run of 50 Wynd Home Purifiers and they’re pretty close to being finalized! There are only two items remaining - finalizing firmware (which enables some of the smart functionality) and the universal power port which allows the Purifier to be used around the world, regardless of voltage or plug type.

Wynd Halo

On the Wynd Halo, we had to make a number of engineering changes which we think will result in a more accurate, better looking, and better performing device. However, while we were expecting to start shipping in May, these changes will result in delaying overall shipments to August. We’re incredibly sorry about this delay, and wanted to explain why we think taking some extra time right now is necessary to ensure a better product experience for everyone.

Wynd Halo is designed to be the most sophisticated environmental sensor system that is incredibly easy to use and beautiful to look at. However, as part of the journey of getting to manufacturing, we faced a number of unforeseen engineering challenges that are now completely resolved. We thought it’d be educational to provide the community with a detailed overview of the obstacles we’ve encountered and the design changes made to Halo since the Kickstarter campaign ended. Specifically, we made the following major changes which improved the overall product but resulted in a delay to the timeline:

  • PCBA (PC Board Assembly) change to optimize sensor placement and improve sensor accuracy.
  • Reconstructed air flow design inside the Halo enclosure to improve Air ID functionality.
  • Changed from micro-USB to USB-C.
  • Switched from capacitive touch to physical buttons.
  • Multiple tooling iterations.
Large improvements with new PCBA including creating distance between VOC and temperature sensors, layout taking into consideration airflow mechanics, and sensor re-arrangement

There are 10 different sensors in the Wynd Halo, and while there’s plenty of space inside the enclosure we underestimated the challenges with interference from the sensors, specifically with heat dispersion. Our VOC sensor is accurate but emits heat (4 degrees Celsius increase to the board), which  interfered with our temperature sensor. We ended up testing 10 different versions of sensor placement to thermally isolate the VOC sensor from the temperature sensor, and ultimately found a successful solution (as shown in the above picture of the PCBA).

Wynd products have always featured a minimalist design aesthetic. In our original design, we had small openings (almost not visible) around the circumference of the Halo to allow air in and out, and three fans inside to move the air across the various sensors. However, this design proved to be too loud and also didn’t diffuse air properly. We had to redesign the internal PM module, and leverage its onboard fan to drive air flow. In parallel, we expanded the openings around the circumference. The result of these changes is a much quieter operation that successfully allows air to flow across all the sensors, while preserving the design intention. 

We changed from micro-USB to USB-C (left versus right picturer), and also simplified the plug so that it plugs in orthogonally to the device. The three holes you see on the right are for screws so that the Halo can be easily opened up in case of future upgrades and easy repairability, but don't worry the holes will be covered up by an overlay.

As many of you know, we originally were going to implement micro-USB to charge the Halo device, but based on community feedback we moved to a USB-C design. We agree it’s the right choice but had to change our mechanical design and the underlying PCBA to accommodate.

Our original design featured 3 capacitive touch pads (one on the top, left, and right side of the front face), and we had several working prototypes with this design prior to the launch of the Kickstarter. What we discovered as we were preparing for production is that getting the capacitive touch pads to work reliably and not interfere with each other (or the LCD screen) was difficult. Rather than risk having functionality issues at mass production, we decided to proactively change to physical buttons that are hidden under the front face of Halo. This mechanical and electronics change is a major one but we think necessary to ensure a positive product experience. 

Tooling iterations. On the left image you can see the preliminary shape of the Halo backside, including the USB-C port. On the right image you can see the front-side which shows the spacing for the LCD screen. We've made more than a dozen changes to the tooling to get the molds right for final production.

Tooling is the steel mold which is used to make plastic enclosures - in this case the outer shells of the Halo as well as the interior sensor module chassis. We needed to make a number of refinements of these tools in order to perfect the fit so that we can manufacture at high yields.

Software Updates

On the app side we’re excited to let you know we’ve developed multiple functionalities including Wynd “Quick Control,” This allows you to seamlessly control multiple devices within a few taps, without having to open different apps or go through multiple clicks to optimize your space. iOS / Android front-end, as well as backend development are well underway.

 Next Key Milestones 

  • Tooling – April completion
  • Firmware + Software Testing -  May
  • Certifications – May 
  • Engineer validation testing EVT - May
  • Design validation testing DVT – June
  • Product validation testing PVT - June
  • Mass Production - July 
  • Product delivery – Shipment begins in August 

 Beta testing program

Thank you for your responses from our last update about getting Sneak Peak of the Wynd Halo and Home. We will kick it off this month with initial testing on pre-production units of the Home Purifier. This phase will be followed in May by testing of the pre-production Wynd Halo units as well. 

We’ll be reaching out to the first 5 who have responded about being a Beta tester on next steps! Please be on the lookout for an email from us. Prior to production, we will also be offering additional phases to the Beta program with more advanced versions of both the Halo and Home Purifier so please stayed tuned.

 OneTreePlanted

 Thank you for your responses. The votes are in, and in favor of planting our trees in the California, where 4,000 wildfires burned through more than 629,000 acres for forests. This past wildfire season was one of the worst the state has ever seen, and as a community we can help!

 As promised, we’re donating funds to plant 1 tree for each backer, which based on our campaign means we’re going to plant 3,150 trees! If we do the math, 2 mature trees can provide enough oxygen for a family of 4, which means we can generate cleaner air for 6,300 people!

Again, we’re incredibly sorry for the delay. Our teams have been working tirelessly around the clock to bring the product to life and made the difficult decision to take the extra time to ensure we deliver you the best possible product. There’s a lot of work ahead of us, but we are excited to continue towards our goal of providing you with quality products that you will love. As always, we will keep you all updated on our progress in a transparent way. If you have any questions or feedback, please email us at support@hellowynd.com.

We couldn’t do anything without all of you. Thank you for your continued support of Wynd— our products, our team, and our vision. 

Best,

the Wynd team

      Since delivery is being delayed can we have the all black option as a upgrade?

      Thanks

      Hi,

      I always expect delays from Kickstarter projects, so no surprise there. The surprise is the detailed update explaining the delay and describing exactly what you have been doing - brilliant and very reassuring, a vast improvement over most project updates which tend to be, to put it politely, somewhat lacking in detail. I know it takes a lot of effort to put together an update like that, but I very much appreciate it.

      This is extremely disappointing, the delay takes it right past allergy season and jumps 3 months. The design looks to have gotten much larger than originally advertised, another draw back. Will there be any give back to the end users for the inconvenience like an additional set of filters?

      I'm very disappointed with the delay :( The reason why I chose the Wynd halo + purifier combo over other similar products was because of the expected shipping date, because it meant getting it just in time for pollen season, but now it'll be coming at the end and won't give us the relief we were hoping for.

      Sad to see an extended shipment delay, but very impressive and detailed update. Keep it up...

      All fine and dandy. Obviously I want to see that you’re improving the product but I dislike how you snuck in at the end that the shipment date just regressed 3 months from the original date in May to August. A third of year is a lot of time and just to have it haphazardly mentioned at the end of an update is shady in my book. Shame on you guys for not being more upfront and owning the 3 month delay at the forefront. I pledged for 3 units and thought my contribution is worth more than that. Disappointed to say the least

      So I can understand the Wynd Halo's delay, but does that mean you wont be shipping the Wynd Home Purifier when its ready? Id prefer to get that first and use it as a normal purifier until the Wynd Halo is done...

      OMG! This finished product is so much clunkier than I had hoped. The design is not at all attractive. Too late to cancel?

      The last time you delayed the Wynd smaller purifier, i received something far better than i expected. That being said, i DO really want to have this in my house, but at the same time i DO really want you to do what you did best last time. Appreciate the update.
