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

Step 2:

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

Step 3:

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.
