The battery of laser pointer can be used to charge

The battery of laser pointer can be used to charge both 16340 battery and 18650 battery at the same time.
green laser pointer has many functions including highlighting content the teacher, lecturer or presenter needs to mainly demonstrate.
Characteristics of pulsed laser ranging using very short laser pulse duration, the relative concentration of energy in time, the instantaneous power (up to MW) in the case of co-operation objectives, pulsed laser ranging can reach a far measurement range; during a few kilometers short-ranging, if the accuracy is not required, just use the measured target reflected signal obtained by the diffuse reflection of the laser pulse, can also be ranging, even without the cooperation objectives. The basic principle is: the time interval between the emission wavelength of the signal and the echo signal, the laser pulse from the laser to the round-trip time t between the test target, you can calculate the test target distance L: ct L = 2 [1 (1.1). The customer can use laser pointer in some special locations for some specific purposes.
If the reference time for the two oscillation cycle only after the D3 plus a D flip-flop can select the module, can be seen in the mode of operation, when the door A1, A2 and A3 separately output is exactly DCAL effective (1), ZERO effective, DCAL and ZERO 0:00, that is, corresponding to the calibration mode, the zero mode and the normal measurement mode. 4.2.4 encoding circuit and counter circuit delay units have an output, and These outputs there is a characteristic that the output of the signal through the delay unit 1. The functions as green laser pointer can be used.
green laser pointer can used to point at the star
Subsequent output to 0, so if directly output to the pin, not only the chip pin a waste of a great and unnecessary trouble, but also to the subsequent circuit design, using the following structure of the circuit of these output encoding, to give a more compact form of the output Q-i the basic schematic diagram of the circuit of Figure 4.6 encoding for the D flip-flop output, two adjacent output is a direct 23 then received with the door with the door after receiving a negated, thus making it adjacent to the two states of the same output after the output and the door is always 0, only the output of an AND gate 1, the gate [10] the location of just ask. The wavelength of laser modulus of green laser pointer is 670nm Class II.
