Ultra-Sonic Ranging Design
The module costs £38.00, and the transducer costs an additional £17.00. The Polaroid module effectively performs its intended function, which requires a certain range; however, it is not designed to serve as the vision system for a small robot. The...
40kHZ ultrasonic transmitter circuit diagram
A 40 kHz ultrasonic transmitter circuit utilizes the LM555 timer as a time base circuit along with external components to create a 40 kHz multivibrator. The resistance of the adjustable resistor RP can modify the oscillation frequency. The output from...
Valve Transmitter circuit 70W
This transmitter, equipped with a quality antenna and utilized under optimal conditions, can achieve a range exceeding 45 km. The configuration benefits from the output lamp's elevation, enhancing the fidelity of the transmitted signal. The 6V6 lamp is employed in...
Medical ultrasonic atomizer 1
The medical ultrasonic atomizer circuit consists of a power supply circuit, an ultrasonic oscillator, and an atomizer circuit, as illustrated in figure 9-110. The power supply circuit includes a timer (Q), a fuse (FU), a current transformer (T), bridge rectifiers...
Ultrasonic-pulsed-pest-controller
IC2 is a stable oscillator whose frequency and pulse width are determined by the values of R4, R5, R6, and C4. R4 is adjustable for precise frequency setting. The output from IC2 is at pin 3, which is capacitively coupled...
Digital Step-Km Counter
This circuit measures the distance covered during a walk. Hardware is located in a small box slipped in pants pocket and the display is conceived in the following manner: the leftmost display D2 (the most significant digit) shows 0 to...
TV transmitter circuit using only 2 transistors operates from 12V
A simple two-transistor TV transmitter circuit that operates from 12V. It is compatible with PAL B and PAL G systems.
The described circuit utilizes two transistors to create a basic television transmission system capable of operating on a 12V power supply....
Electronic mosquito repeller
The circuit diagram of an ultrasonic mosquito repeller is based on the principle that insects, such as mosquitoes, can be repelled using sound frequencies in the ultrasonic range (above 20 kHz). The circuit utilizes a CMOS 4047 PLL IC configured...
televition transmitter
The camera is oriented to look out the side of the rocket during launch and downward during descent on the parachute. An optional external mirror can be added to enable the camera to look down during lift-off. The transmitter antenna,...
