Picture of simple cabinet led light with recycled power adaptor

Everyone has power adaptors that have no more use.

From old laptops, portable phones and all sorts of portable machines.

Don't throw them away !!!!!!!!!!!!!!!!!!!!!!!!!

Look for the 12volt and 9 volt adaptors.

We can use these as power adaptors with 12 volt led light strips.

Step 1: What do we need ?

An old adaptor  12 volt or less.

One or more led strips 12 volt.

Something to connect these.

I am doing something kind of similar. I am utilizing a 12 volt LED bulb assembly that I wanting to power with an old cordless phone charger. The LED is 12 volt and is 140 milliamps. The charger is 9 volt and 210 milliamps. Will this be enough to power this and will I need to worry about getting the milliamps down with a resistor?

Wonderful 'ible; love the recycling aspect.

I have a quick question. Is the adapter necessary? If I were to cut the end of the adapter and identify the + and - wires, could I just connect them to the appropriate wire of the LED strips, shrink wrap them, and go?

This would make the overall project cheaper at the cost of not being able to seperate the LED's from the power adapter.

but the adaptor, you need
