When it comes to charging your iPhone or iPod there are so many different designs depending on the model you have. Have you noticed that no matter how hard you try there always comes a time when you need to re-charge and lo and behold you don’t have your charger or you are nowhere near a store where you can go and purchase one. Talking of which, these chargers don’t come cheap do they? There is no such thing as a cheap USB charger…until now!
Great stuff! I love simple innovation especially when it comes to knowledge that could possibly get you out of a situation. The info below is for those of you who prefer to read instructions. Click through to read the whole article.
- 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 Read More…
Now of course you need to be fairly competant in this and you need to make sure your soldering is up to scratch. The author does point out that there could be a risk if not done correctly of damaging your ipod…so probably not for the faint hearted.
Here is another idea, I love the information that can be found on indestructables…
LM7805The parts needed for this project are all in the second picture.
You will require:
LM or MC 7805 +5VDC Voltage Regulator
Type-A Female USB Port
100 UF Electrolytic Capacitor 10-50v
0.1-0.5 UF Capacitor 6-50v (any type would do)
150-160 ohm Resistor (optional)
9V Battery clip
2.2V 20mA LED color of your choice (optional)
Unprinted circuit board
ON/OFF Switch (optional) Continue Reading…
