to fit in or cut a square/hole into the side of the heat sink for it to fit. well, it was from a laptop so the laptop cooling fan is connected to a heat sink to cool the laptop faster. Now, you might be ready to reply to me saying that this doesn't help your case at all. Finally I looked at the recording and found my + and - terminals. Each time I tested a connection, I would call out both pin numbers and which one was positive/negative. Camera's can "see" IR (that's how night vision works) so I labeled each pin 1-4, turned off the lights and started using my laptop camera and screen recorder (Screencast-O-Matic). turned on and was red while the other looked like it didn't work. You have to try every combination so be happy it's only 4 pins and not 8, 12, or 16 pins. What I did was using a AA (1.5v), test each pin to see which one is + and which one is. 1 is the dvd (red) and 1 is the CD (IR, looks like nothing is happening or pinkish). For answers to any laser related questions, check with one of the popular forums like Mine look similar because I got a DVD/CD burner/player (It did all of the above so i'm lucky) from an old laptop.
HOW TO MOD A LASER POINTER DRIVER
If you want to do that, a driver circuit is highly recommended.
Ths is a novelty item and not designed for long-term or regular use. The basis for this project was to show that you could use a diode from a DVD burner and put it in a flashlight and make it 'burn'. Why can't I see the beam like I can see in the video? A. In order for the diode to 'burn' it needs to be focused to a fine point and also the object needs to be black or marked black with a Sharpie. Can I use a regular laser pointer from the dollar store as the housing. They are soldered to the diode and then inserted in the mini-mag plastic fitting that original held the mini-mag lightbulb. The 'pins' are snippings from old resistors. You can keep it for a lower mA diode like a standard red laser pointer diode or just discard it. What happens to the existing circuit board that is inside the Aixiz housing? A. It serves as a heatsink for the high-power diode and also the focusing element is essential. Only a DVD burner diode 16x or faster will work. Can I use a CD player/burner or DVD player Diode. Here are the answers to common questions about this project.
