Hey Kelly, I saw a vid on Facebook for a car charger that u can turn int9 a 9v charger for your phone, I've already completed this project and looking for more fun things to build.
Have you checked out the various magazine repositories?
There are websites that archive old electronics magazines that are full of projects of all sorts for the DIYer to build. I have a collection of over 100Gb of magazines that I use just for reference purposes but many of them are available for free download at the archive sites.
