Stretch Goal Reached!
Thanks so much for all the support!
We are very excited that the stretch goal has been reached. It means harmony between Android and iPhone users, a simpler choice for everyone and a better product overall. (Well maybe not harmony between Android and iPhone users...) We will be updating the project page soon to reflect the change to the Dual Mode Bluetooth model.
The next stretch goal
We don't have one! There have been some great ideas put out there but nothing that we feel we can actually promise and deliver in a reasonable amount of time. People have been asking for higher resolution for the sensor, it would be great but we can't find a sensor with better resolution that is anywhere near the cost of this one. You could add a lens to change the resolution of the sensor but the IR lenses we have found are more expensive than the cost of the sensor itself.
So, if you have a great idea for a stretch goal let us know and we will see if it can be done.
If you are a PCB backer the change to a Dual Mode Bluetooth module makes the soldering of the module much harder since the pads are only under the module board. You would need to be comfortable using solder paste and a reflow oven or skillet to mount the module. So, you will have the choice of the Bluetooth 4 only board, the Bluetooth 2 only board or the Dual mode Bluetooth board. The Bluetooth 2 only and the Bluetooth 4 only boards each use a module that can be soldered by hand. You will be able to pick which one you want after the Kickstarter ends.
Here is a video of the assembly of a Bluetooth 4 version PCB.
I just wanted to share a snapshot of how our window in the living room leaks air. The trim is cracked and even with some window caulking it is still bad. I think all the trim needs to come off to see how bad it is behind there.
