Batteries Not Included

So I've been enjoying my indoor/outdoor temp/humidity sensor for a while.

But a key problem has been keeping the batteries topped up so that the LCD display doesn't go all dim and washed out. It naturally takes two AAA batteries and those don't hold a lot of juice.

So eventually I got tired of recharging the batteries every 2-3 weeks and decided to take slightly more drastic measures.

That ain't gonna run out for a while.
