Solar Lamp Hack to Run Off Wall Power!

This Ikea Solar Lamp, that I bought at Ikea, has a solar pack that charges batteries to power the 16 LEDs inside. This is very bright, but what if the batteries died and there is no sun because it is cloudy outside or for some other reason? Well now you can plug it in and it will run off the main supply! This is the first Ikea Solar Lamp hack to run off wall power.
IF YOU RUIN THE LAMP, IT IS NOT MY FAULT. THIS IS AN EDUCATIONAL HOW-TO PROJECT FOR THE SAKE OF THE LAMP.


Materials...

You need:

Ikea Solar Table Lamp ( I bought at Ikea)

5v Small Transformer (was a cell phone charger...)

22 Ω Resistor ( RED   RED  BLACK ) It is okay to use this resistor. It won't ruin anything.

Diode (found in common electronics! 1 amp diode will do!)


Tools:

Soldering gun
Solder

wire

Philips screwdriver

Drill (to make hole for wire to come out to transformer)

Helping Hands 

Wire stripper


Start

Start by taking out the solar battery pack.
Take apart the base of the Solar Lamp and take the two screws out of the connectors plate.

Mark the negative side with a marker so you don't mess the polarity up. 

Solder the 22 ohm resistor to the positive side of the connector. Then the adapters positive wire to the 22 ohm resistor.

Solder the negative side of the adapter to the negative side of the connector plate.

Jam it all in the plastic case thing. MAKE SURE you don't have anything touching that should not be touching.
Put the connector plate together to the dark base. Don't completely put it together yet.

I drilled a quick little hole for the wire.

To the battery pack! 
Add the diode coming from the circuit board, to the connector. (See photo)
You don't want the 5 volts going into the circuitry.
You're done! Put it back together carefully.
