Simple laser flashlight circuit diagram [Copy link]

The following figure is a laser flashlight circuit diagram. The circuit is very simple, and it only needs a battery, a resistor, and a transistor. Laser flashlights are cheap and good quality, with a very high cost performance. The main feature is excellent focusing performance, with a range of 1200m~1500m. Observed with the naked eye, the light spot is still very small hundreds of meters away, so it is widely used in teaching, tour guides, and entertainment. After testing, it can be used for long-distance protection and remote control data transmission. As shown in the figure is the principle diagram of the laser flashlight, the devices are all surface mount components, so the size is very small, but because the laser power is large, it cannot be directly pointed at the human eye.
