Make a bird house with solar power night lights. via instructables
I recently stumbled onto a really cool night-light by Instructable user boddhi15. This got me thinking about building my own outdoor one. I decided to hack a solar power light and add a couple of little lights out the front.
The actual hack isn’t very hard, it does however need a voltage regulator to ensure that the circuit from the solar lights works correctly. The usual voltage that the circuits deal with is 1.2V. This has to be upped to 3.6V using 3 x 1.2V batteries. If you just used the 3 batteries, they would light up the LED’s but not very brightly. The problem comes from the circuit board not coping too well with the extra voltage which causes the LED’s to be on during the day. They LED’s would be very dim, but you don’t want them on during the day as the solar panel won’t be able to charge the batteries to their full potential. The voltage regulator fixes this issue and ensures that they only come on at night.
I’m hoping that the lights will attach some insects for the birds to eat!
No birds yet but it’s early days.
