Introduction: Waste Batteries Night Light
My son wanted a night light and I had loads of used batteries just waiting to be recycled but I knew I could still squeeze some juice out of them so I build this with an old broken mini fan I also had lying around.
Step 1: Materials:
One broken mini fan (burned motor removed)
Three RGB Led's
Open the mini fan case and remove the motor and fan blade.
Solder the three Led's in parallel (all + together and all - together)
When I soldered them I used the vent holes on the fan cover to match the led's
Solder the old motor cables to the Led's (make sure to get the + and - cables right as Led's are polarity sensitive)
Rebuild cover and insert some used batteries in it.
Old used batteries always have some juice left in them and can last a few nights.
We have a be nice policy.
Please be positive and constructive.
