I've seen people use IR to re-program Arduino boards before, and I think it would be pretty cool if someone wrote a self-replicating program that could be passed on just by standing in front of another attendee for the length of a normal short conversation. I'm guessing someone could come up with a pretty interesting/artistic use for a botnet of a few hundred Arduino badges in one location.
Good plan - we'll be putting up some framework code on the TiLDA repo at https://github.com/emfcamp/TiLDA, so feel free to submit pull requests before the event.
I want to see a simple mesh network running across the badges, or maybe some stationary base stations that use signal strength to real time track each badge at the conf - and a big map overhead showing you where everyone is. Page a badge and it shows up on the map for approx location. That is going to be a fun conf.
We'd love to do something like this - we're placing "beacons" around the site to provide uplinks for this kind of thing. We'd also like people to be able to see who they met up with or spent time with. But time's pretty tight, as the badges only arrive a week before the event, so submissions will be welcome.
We really should have mentioned them in the blog post as they're sponsoring us. It's obviously a big plus to have these being fabricated in the UK instead of China due to our really tight lead times.
Curious as to how much these cost to produce? I have been playing around with some Arduinos and it seems like getting something set up with wireless and a rechargeable battery is a lot more expensive than it should be. Would be cool to have an all-in-one solution for this.
