At Christmas we put lights on everything. We light up our trees, our houses, and even our lawn ornaments. So why not put lights on the presents as well. 

Most people don't want power cords running to their presents. So in this project, I am going to show you how to make a light up Christmas present that is safely powered by induction. That way there are no visible power cords and your present isn't tethered to the wall. It will just light up when you place it under the tree.

Step 1: Select an Inductive Charger

For this project, you need an inductive charging system. This kind of system uses a transmitter circuit to convert electricity from a wall outlet into electromagnetic energy that is wirelessly sent to the receiver. The receiver then converts the electromagnetic energy into electricity that it uses to charge mobile devices.

I am using the PowerMat inductive charger. In this model the transmitter is a thin plate that the receiver sits on. The receiver is a small disk with a mini USB power cord that plugs into the device that you want to charge. When the transmitter detects the presence of a receiver unit, it automatically turns on and begins sending power to the receiver.

You don't need to use this exact model. Other inductive chargers can also work. If you are interested in building an inductive charger from scratch, you can check out this Instructable from user Inducktionhttp://www.instructables.com/id/Wireless-Ipod-Charger/

<p>I built this but I just used a LED Matrix with a 6V battery, some RGB LED flashers, and a few resisters I had lying around. I recorded a time-lapse of the construction of the project (My first time-lapse ever).<a href="https://www.youtube.com/watch?v=_QBYCxzOrBc" rel="nofollow">https://www.youtube.com/watch?v=_QBYCxzOrBc</a></p>
That is a nice alternative use for the charger but it would be cheaper to use the batteries and a magnetic switch.
<p>sir..</p><p>what, if we use an LED matrix ( 9V battery , 3V LEDs, and some 1K resistors. ) or a ckt like this with 9v battery .</p><p>maybe it is easy and portable !!</p><p>isn't it ? what do you say ?</p>
cool how much dose it cost to do this with and without the charger you bought
The lights were about $5. The diode was about $1.50. An inductive charger can be anywhere from $30 to $100 depending on the model that you get.
