How To Make Laser With Dvd Player

Laser is one of the most popular toys for kids. It is easy to make and can be used for many purposes. The laser can be used as a toy or as a tool to burn different materials. This article will teach you how to make an amazing laser using a DVD player. You’ll also learn how to make a laser pointer stronger and how to make a burning laser pointer out of household items.

How To Make Laser With Dvd Player

Turn a MiniMag flashlight into a powerful DVD laser pointer! This 245mw laser is powerful and fits real cozy in a MiniMag! 

Step 1: What You Need…

You will need the following items:
1. 16X DVD Burner. I used an LG burner I had as a spare.
or…
You can buy the Red LASER DIODE

Step 2: And…

2. A Mini-Mag Flashlight

3. An AixiZ Laser Module.

4. Small jewelers screwdrivers, X-Acto knife, metal snips, drill, round file and other small tools.

Step 3: Extract the DVD Laser Diode

After removing all of the screws from the DVD burner, remove the cover and the DVD drawer. This will expose the laser carriage assembly.

Step 4: Extract the Laser Diode..

Extract the Laser Diode..

While all DVD burners are a bit different, they all rely on 2 rails that the laser assembly moves on. Remove all screws and do whatever it takes to free up the rails so the laser assembly slides off. Disconnect or cut and cabling and flat connectors.

Step 5: Continue Extraction…

Continue Extraction...

Once you have the assembly off of the burner it’s time to start disassembling it by removing all the screws you see. There will be many small screws so be patient. Cut any flat cabling off. There could be two diodes, one for the CD portion of the burner (IR diode) and the actual DVD burning diode (red). That is the one you want. There will be a 3-pin circuit board on the red diode that you want to CAREFULLY remove with a soldering iron revealing 3 pins. You can test the diode with 2-AA batteries and referring to the polarity chart (on the video). You will have to remove the diode from the housing and that will be in a case-by-case basis depending on the burner. The laser diode is fragile so take care in the final extraction process.

Step 6: The New DVD Laser Diode!

Step 7: Preparing the AixiZ Housing…

Preparing the AixiZ Housing...

Remove the label from the AixiZ housing and unscrew the housing leaving a top and bottom portion of the housing. Inside the top housing is the original (5mw) laser diode that has to be removed. I used the bottom of an X-Acto knife and with a couple of sharp taps, the original diode will come out. It will likely be destroyed doing this but I have been successful in removing them before but using a very small screwdriver and tapping around the diode until it is freed up.

Step 8: Assembling the Housing…

Assembling the Housing...

I used a little bit of Arctic Silver Thermal grease and slowly installed the new DVD diode in the AixiZ housing. Using a pair of pliers, I SLOWLY squeezed the edges of the diode down into the housing until it was flush. CAREFUL!

Step 9: Installing It in Your MiniMag!

Installing It in Your MiniMag!

After soldering two leads to the positive and negative diode connectors, it’s time to install it in the MiniMag. After disassembling the MiniMag (remove the top, the reflector, lens and bulb) you will need to enlarge the MiniMag reflector using a reaming tool, round metal file or drill or a combination of all three.

Step 10: Final Step!!

Final Step!!

Be sure to remove the batteries from the MiniMag and after checking polarity, slip your new DVD Laser housing down into the top of the MiniMag where the bulb would go. Screw the top of the MiniMag on and slip the reflector over the Laser housing. You will not be using the plastic MiniMag lens.

UPDATE: If you intend to use this as more than just a novelty item, a driver circuit is recommended. Here is a basic driver circuit that can be built for this project which will regulate the voltage going to the diode.

Step 11: Test It Out!!

Test It Out!!

Reinstall the 2-AA batteries and slowly unscrew the top of the MiniMag, turning on your new Laser Flashlight! Caution!! Laser diodes are dangerous and should never be pointed at any living thing. Thanks and I hope you enjoyed this Instructable!
