Today, a milestone was reached:

That’s nearly half a million packets, one every 64 seconds, all on a single LiPo battery charge:
The setup is very simple. A 1300 mAh LiPo battery (I just picked one up in a camera shop with a convenient size), attached to a JeeNode USB:
At 3.94 V the battery is still far from dead, so it’ll probably stay alive for quite a bit longer…
The sketch running on this node is:
(looks like I had lost the low-power stuff in the “radioBlip” code, now fixed on GitHub)
Lots of low-power nodes are holding out nicely here at JeeLabs, by the way. There are about half a dozen permanent room nodes, and with the latest roomNode sketch they just keep going. Some are running on 3x AA rechargeable EneLoop batteries, others use 3x AAA with even less juice, and all of them have been running with just a single charge since the beginning of this year.
