Here's another example of a real-world use. A friend of mine moved across the country. He had a car shipping company ship his off-roading truck. When he got his truck back, some of the contents had been removed and other contents were not his. It looked like the shipper had driven his truck into the woods and had a camp-out, because they left camping supplies.If he had had a GPS tracker in his vehicle running under the dash, he could have shown the owner of the shipping firm the proof that one of the employees had taken his truck for a spin.

Randy:The switch for the 9V battery is an ALPS SSSU012200.You can buy them from Avnet for 24 cents each.https://www.avnet.com/shop/us/products/alps-alpine...To replace it you would need to desolder the old switch with a pencil soldering iron and desoldering wick/braid OR a desoldering suction bulb.
For Step 11, it's a good idea to add hot glue or epoxy to glue down the AC port. It snaps through the board, but I found that mine would lift up when pushing the AC cord into the port.
