Same. What was the widget? Been thinking of hiring someone to do some board layout work to build these.
It's just an off-the-shelf Barix Barionet 50. It does the job well, and only draws a watt or two (literally).
Not terribly impressive, but $150 worth of my own work wouldn't have been able to drop the power usage to those levels.
It might be very interesting to chat.
I'd appreciate if you dropped me an email to dfong <a.t> lightsailenergy.com :-)
