Very nice device! I have been spending too much lately or I would definitely get one! That said I backed you for $1, and shared the kickstarter to show support and keep updated on your progress! It would be awexome if you guys decided to make it all open source as well… so much potential for customizing this device it would be a shame if it wasn’t open source.
I wish it was possible to understand how the device wakes you up… if not vibration… is it at least moving? What is the frequency that the linear actuator operates at?
You might consider putting the WiFi to sleep until it’s time to wake up the user, so you can claim the RF energy is OFF completely while you are sleeping. Many people have a fear about RF energy long term near their head. Honestly I don’t think it’s going to hurt you, but you only get one chance to find out
Good luck and make it a success!
