There are many designs for iPhone chargers out there and many are confusing or use parts that are hard to find. My design uses parts that are easy to find, is tested works with all iPhones and iPods (as of this posting), and just works. It is a fun and useful project. I made one a few years ago and put a video on YouTube. I weekly get many questions about making one. So here you go and i hope you enjoy it.
Step 1: Parts List:
- 1 - SPST Switch (I used a toggle switch)
- 1 - LED for "ON" indicator red or green (Radio Shack sells LED's with resistor "350 ohm" you can mount. That's what I used.)
- 1 - 350 ohm Resistor
- 1 - 7805 Voltage Regulator
- 1 - 22uF Capacitor
- 1 - 10nF Capacitor (code 103)
- 2 - 33K Resistors
- 2 - 22K Resistors (Other values can be used, read step 2)
- 1 - Female USB Connector (I got mine at a dollar store)
- 1 - 9v Connector
- 1 - 9v Battery
- Electrical Tape
- Soldering Iron
- Small piece of perfboard
- Altoids Tin
- Dremel Tool with cutting attachment or tin snips to cut the tin
- Drill for switch and LED hole
- Hot Glue
- Paint if you want

For most of the parts you can use techno scrap and recycle old broken electronics or just buy them.
I wanted to use parts that are easy to find and inexpensive so everything can be bought at Radio Shack or if your don't mind on-line shopping I like http://www.taydaelectronics.com/servlet/StoreFront because it's cheep!
I hope you enjoy the project.
Warning: Just a fair warning that there is a small chance that something can go wrong and you can end up frying your really expensive iPod. Be careful.
