Hi Guys,
I thought I'd post an Aussie Kickstarter my wife and I have been developing, for some scrutiny, questions and/or suggestions (I'm a tech guy and write like one, so if you have some marketing advice that would be awesome too). It's based on the Atmel ATREB233SMAD-EK development platform and gives pretty accurate line of site positioning for hobbyists to play and experiment with. The boards we are releasing are a versatile 2.4GHz RF platform that not only measure distance and position between each other, they can even passively detect motion without any client hardware (see the updates for a demo video), or be used for a variety of other RF purposes (it uses the Atmel AT86RF233 chipset).
Anyway, here goes.

Can't hear your voice over the music, so thanks for the subtitles.
I think this is an old person thing rather than a clarity issue as I've only recently noticed it, although a better microphone helps.
This has to work on a cat, all other applications are less interesting.
It's £31, for anyone in the UK (+shipping?)

Oh really? Thanks for that! I'll play it back on a few devices and try to get the volume right and re-upload.
It will definitely work for cats too. I just need to borrow a cat to demo it :P
Edit: I've just adjusted it a bit, hopefully the background music doesn't drown out the voice now.

Apparently it's a degradation in temporal discrimination (the cocktail party effect) rather than a hearing loss

sorry for the tangent, just adding to my trivia collection
anyhoo, if you wanted to cover a larger area (say a Uni campus), would you just add more boards?
I've heard of less accurate systems that just use whatever wi-fi access points are in range.

You could definitely do it, however you do need the client to get the distance measurements. I have created a "dataless" Wi-Fi positioning system that the Ranger works with to support this sort of functionality (http://subpos.org/?q=details (http://subpos.org/?q=details)), but I don't think it would see wide support because of the hardware requirements.
Just using the Wi-Fi positioning system on its own however works with most smartphones that allow you to use the Wi-Fi scanning APIs (not Apple unfortunately). So if you don't mind the lower accuracy you get from distance measurements with RSSI, you could use that (it's all open-source).
