November Progress Update
Good day Kickstarter backers,
We realize your frustration and have read all of your posts. Yes, we are running behind the schedule that we have shared in the past and we understand this is disappointing. In reading the unhappy comments that some backers are posting, we wanted to set the record straight. All money raised from investments in FreeWavz from both Kickstarters like yourselves, as well as private equity investors, has gone to the design and engineering of the product. Freewavz’s management has never received a salary of any kind and their compensation is entirely tied to the success of the company. All funds and resources that come to Freewavz are used to pay both operations and engineering contractors. We are working to set a new standard in Hearable Technology and are committed to bringing a quality product to the market. That said, we have a number of engineering challenges to solve, but we are committed to delivering the Freewavz to market.
- We are having difficulties realizing ear to ear wireless connection with consistency. The tuning and design of the PCD trace antenna is extremely challenging. 2.4GHZ standard BT protocols work well with single point to point implementation, but running the True Wireless Stereo with one earphone being a master and the other being a slave has caused severe drop outs in the stereo single. This problem has proved difficult to isolate and problematic to solve. We have several RF engineering experts both in the US and at our factory in China working on the problem of re-tuning and redesigning the antenna, but this is taking more time and money. We are also considering options that might allow us to realize another methodology to use a separate frequency from standard BT between the ears for stereo delivery.
- We are in the process of updating the design of the shrouds on our earphones to give us better Transmissive Pulseox results. We are delighted to have shared in our last update that we have gotten good and fairly consistent resting pulseox readings for both HRM and O2 saturation. When exercising, we saw an unacceptable increase in interference that tasked the proprietary algorithms we developed for pulling out HRM and O2 sat. We have customized shrouds which help fit the earphone more flush to the ear on both sides of the ear’s conchal bowl. This will give us the consistency needed to supply stable HRM and O2 and will actually help fit the driver of the earphone more securely and comfortably on the ear. We are in the process of finishing the design and testing.
- Although we have seen some success in pulseox readings, we are experiencing less than targeted battery performance. Our engineering team is working on tracking down the power-loss. We believe there may be a higher than anticipated draw from the pulseox but more testing needs to be done to isolate the power drain on the planned 5-6 hour performance.
So to summarize, we are going to be delayed and not make production within 2015. We are committed to producing a quality product and are devoting the time and resources to solve all of our challenges. Until we have a better handle on how to provide quality solutions to the engineering issues we cannot provide an updated production schedule. We hope in the coming weeks to share with you an updated schedule. Here is some bright news. Recently, we were given the opportunity to meet with engineers from the National Aeronautics and Space Administration (NASA). Yes the same federal agency that put a man on the moon, has created a program to help startup companies solve technical problems.. Turns out that NASA engineering is very interested in our application of wireless pulseox. They have agreed to devote resources in helping us solve our pulseox challenges that are mentioned above and we have asked for help with the RF issues. Well, that’s about all for this update. We continue to be optimistic about bringing a quality Freewavz product to the market.
