      Any update for your backers? Even "a dog ate my Heartsat"?

    3. Creator Michel on March 10, 2013

      Nothing on the Web site and anemic Twitts. I tryed to trck the payload but the page was not working.
      I only know today, March 10 that you recover the payload.
      May you give more feedback the your backers?
      I'm waiting to see the video and to get (to choose!) my reward.

      Thanks for the comments! So happy that you enjoyed watching the launch live, Kerry. Retrieval of the payload has been on my mind all day; we're going to check in on it tomorrow to see if it has physically moved at all. The winds in Londonderry, NH are gusting high this evening, and with a little luck, it may come free. We're also getting in touch with people who have experience with trees to see if it is possible to have it removed by hand without having to wait much longer.

    5. Creator Kerry Cupit on March 4, 2013

      Yes, awesome job :D It was exciting to follow via your Facebook, Twitter and website updates on the launch yesterday. Now to get it unstuck from that tree, heh. Good luck!

      Congratulations on the flight team!

    7. Creator Heartsat.com on February 13, 2013

      We're all very eager to get this project off the ground, literally, this time. There is a possible launch opportunity next week, weather dependent. Keep your fingers crossed!

      Stephen, we're waiting for the remnants of Sandy to disappear and high altitude winds to once again be in our favor. Stay tuned to our social media channels for updates on the launch date, and be sure to tune in and follow the launch in real time.

    11. Creator Stephen Teng on October 31, 2012

      When is the launch date?

      May your balloon fly into the heavens and your calculated numbers equal positive results.

    13. Creator Nik B. on September 12, 2012

      Good luck!

      Look forward to seeing how it all turns out.

    14. Creator Heartsat.com on September 12, 2012

      Thanks for the kind words, everyone. A survey requesting information to fulfill the customized rewards will be sent out within the next week, so make sure you keep your eyes peeled, backers. Thanks again!

      Good luck on your project!!

      I think that it would be a more easily realized goal to proceed without the control surface even being a consideration until you finish everything else first. Then add that on if you feel there's enough time/money/motivation left.

    17. Creator Heartsat.com on August 29, 2012

      The idea behind a control surface is not to guide the descent, but stabilize it. I do agree that it adds a new level of complexity, but one that should not interfere with overall mission success. Do you have any other thoughts to add? I know you have expertise in this type of thing. Perhaps there is a more simplistic and finite goal; I'd love to hear suggestions.

    18. Creator Gleb Polyakov and Igor Zamlinsky on August 29, 2012

      Are you sure that doing a guided descent is the best way to go with this? It sounds like it'll just complicate it, and cause a lot more headaches and potential failure points for you.

    19. Creator Heartsat.com on August 26, 2012

      Jean-Luc, thanks for your kind words. Additional funding is going towards the spectrometer mentioned in the recent project updates. Funding beyond that is going towards additional components for the flight computer including additional sensors.

      I very much like the idea of a controlled descent, though. I may begin looking at how to add a control surface onto the vehicle to make that a possibility, but it's certainly an engineering and programming challenge - but one that I look forward to taking on. If completed, it would certainly be the first time it's been done on a high altitude balloon to my knowledge.

      Stay tuned! You might see some interesting new drawings and ideas in the updates section. ;)

    20. Creator Jean-Luc Nacif Coelho on August 26, 2012

      You're smart. You have a bright future ahead of you =)
      Ever think of making an autonomous gliding payload with the spectrometer attached to it with the extra money?
      You can buy gps sensors, accelerometers and pic microprocessors cheap these days.

    21. Creator Heartsat.com on August 26, 2012

      The flight computer which records GPS location, atmospheric parameters, and controls flight termination will hopefully be made into a custom PCB. Assuming that happens, the schematics would certainly be released for those interested in a DIY kit. Thanks for asking!

    22. Creator Gleb Polyakov and Igor Zamlinsky on August 26, 2012

      Yeah! I think something like that would really help you in raising funds. Are you going to release the schematic design of the sensor/control board that you put together?

    23. Creator Heartsat.com on August 26, 2012

      Gleb Polyakov and Igor Zamlinsky, thanks for your generous support of HEARTSAT. I love the idea of a DIY kit for a reward level! I'm examining the possibility as we speak, so please stay tuned.

      Thanks again,
      Andrew

    24. Creator Gleb Polyakov and Igor Zamlinsky on August 26, 2012

      Awesome! You should consider adding a simple DIY kit as a reward level!
