Thanks for sharing, I found your tips very helpful. I tried to reach out people, press and get some contacts in shows and fairs before I started mine. So far it's going good in the first couple days. I hope my project will turn out good like yours! It is so important to start it way earlier before the launch date. I think whatever you have accumulated before launch will make a huge different.
One more thing, you have to be very careful about what you are saying and offering in comment and in rewards, once it's launch or posted and someone backed, you can't edit it anymore. I made few mistake and very regretful. Make sure you planned for updates and the right answer for questions.
Here is my campaign, any tips and comments will be highly appreciated.
