Advantages and Disadvantages of Laser Lighter
Advantages: not affected by climate, environmental protection, resource saving (but waste of energy, because the electro-optical conversion efficiency of the laser is relatively low), and can also be used for other purposes (such as positioning).
Disadvantage: The power requirements are relatively high, and the precision machining technology requirements are relatively high.
The composition of the laser lighter
The laser lighter is roughly composed of three parts: the power supply (possibly It can also be connected to a charger), control system, laser output system (if the output laser characteristics are better, there is no need to connect the optical system to focus).
How to make a laser lighter
1. Find a small flashlight, which can hold two Cut off the 5th dry battery, remove the light bulb of the flashlight, and wait for a spare.
2. Find an old DVD drive, but you have to make sure that its laser head is not broken, disassemble the DVD, and then take out the laser head.
3. Put the laser head taken out from the DVD drive in the prepared small flashlight. Note that the positive and negative poles must be connected firmly, and the small bowl that condenses the light in the flashlight must also be installed. Such a miniature laser weapon is ready.
4. This laser flashlight can light matches and cigarettes in a short distance, and can also explode the balloon. However, you should also pay attention to safety during the playing process, and there are still dangers.
