@Quantumcrazy Yep that works great you can test them with a battery and jumper cables they hold a lot of electronics. Note; make sure all of the inside of the can is covered with card board Top and Bottom how to measure put the card board to the the bottom of the garbage can use magic marker cut the circle out w/scissors for a clean cut repeat for under the lid you have to find a box big enough to fit inside the can then trim off excess!
