The laser of the DVD drive with your hands

Many a child was a laser pointer, which can be purchased in toy stores. But with the development of modern technologies there appeared an opportunity to create a laser of the DVD drive with your hands. This will take just a faulty DVD drive (it is important to remain serviceable the led), a screwdriver and a soldering iron.

It Should be remembered that the creation of laser is best to use a non-working DVD! This is due to the fact that after dismantling and extraction of the led it goes down. Do not forget that the laser of the drive is much more powerful than normal pointers and can cause irreparable harm to health, therefore, never need to direct the beam to human or animal. In the beam of the device on the human eye is burning of the retina, and the person may partially or completely lose vision.

So, let's create a laser of the DVD drive with your hands. For this you need to gently Unscrew the bolts on the rear of the case to get to the led's the future of the laser. Under the cover is the node that performs the drive of the carriage. In order to remove it, Unscrew the screws and unplug all cables. Then remove the carriage.

Now you need to disassemble it, which should loosen the many screws. Next are detected two LEDs. One of them is infrared, it is responsible for reading information from the disk. Need red, which is burn to the disk. The red led will be attached to the printed circuit Board. In order to disable it, you need to use a soldering iron. To verify that the diode is enough to connect it to two AA batteries, but it is important to take into account their polarity. Remember that the laser diode is fragile, so it is necessary to be very careful.

Next you need to buy any laser pointer. Creating a laser of the DVD drive with your hands, use it as a "donor" for the case. After purchase, you need to carefully spin the pointer into two parts and extract the upper half of the laser diode. You can use the knife. It is important to do everything carefully, because it can damage the diode. Using a small screwdriver, choose emitter. Using hot melt glue, install the new led into the housing. And that he is well established, you can use the pliers, pressing them on the edge of the diode.

The Laser of the DVD drive with your hands is almost ready. Before you run it, you need to ensure that you have correctly identified the polarity. Now you can safely plug the power. After the first run you may need to adjust the focus. You can then set the pointer in flashlight and connect the AA battery. Don't forget that the laser can burn a variety of items, so you need to remove the plexiglass from the lens.

A Well-tuned laser of DVD drive can not only burn the paper, or lighting matches, but also to leave a mark on plexiglass, blow up balls (better if they were black) and leave visible marks on the plastic. If you install the diode in the head of a plotter, you can engrave on plexiglass.
