Thanks! I actually haven't seen those, they look pretty good, basically replace the custom schematics I needed to build.

The timing calculation still needs to be done somewhere though, I wish there was a module that would do it internally and just publish the timing numbers - that would be more scalable and then even Arduino would be able to handle several sensors.

From what I understand, the official kit includes software for calibrating a specific configuration of sensors in fixed relation to each other and figuring out the timing parameters. Guess I find out for sure tomorrow!

Yeah, you've basically done all the hard work. I just ordered a batch of these to see if I can get it working. I've been wanting to hack on this since they came out. Thanks for the inspiration!
