This study deals with the problems, structures, controls of industrial robotic arms and their role in Industry 4.0. The study describes the development and realization process of an industrial robotic arm model with 3D printing. Besides building the model, the job deals with firmware, software and inversion kinematics which are crucial for control. Detailed and…
The purpose of the Motor Driver Test card is to check any of the motor drivers used especially in CNC machines. The tester is connected directly to the motor driver board instead of the interface. The tester has 4 switches that determine the state of Direction Signals (change direction of rotation), Enable (drive enable), Step…
A simple 0-30V 0-3A regulated power supply circuit based on the NE5532 opamp IC that you can use in your electronics workshop. Basic parameters of the power supply: Input voltage 24 – 26 V AC, DC output voltage 0 to 30V, Output current 10mA – 3A. It’s an open circuit. The current limiting resistor is…
Simple 555 circuit. The water tank filling circuit is based on the NE555 timer IC. By measuring the water level in the tank, it automatically starts the water pump motor at low water level and stops the water motor when the water in the tank reaches the specified level. The circuit can be used for…
100W Amplifier circuit provides high power with less material. Output transistors 2 2SC5200 NPN transistors. PNP transistor is not used for output in this amp design. The operating voltage of the 100W Amplifier circuit is 2X46V DC. If you want to operate at higher voltage (max. 2X56V DC), you should use 2SC3858 or similar power…
Compared to the previously shared Li-Ion battery balancer battery balance circuits, it is a simple circuit that you can make with less material. Li-Ion battery stabilizer is a system that controls the voltage of each cell/cell section and does not allow the charging voltage to be exceeded. If one of the cells is charged earlier,…
The vu meter circuit, which can operate peak hold and normally, has a 2×20 LED peak indicator. Leds are controlled by Atmega8 microcontroller. The display range is -34 to +4 dB. The LEDs are controlled by multiplexing 4 LEDs in 10 steps, the multiplex frequency is about 100Hz. R1 … R4, their resistor (270-ohm) limits…
I tested the Joke Remote on Samsung, Toshiba, Arcelik, Vestel televisions. It can turn on and off. Arcelik TV was a very old model, it only turned it off. 2021 model toshiba also turned it on and off when the button was pressed. Keep the button pressed when the TV does not turn off. There…
When I found a regular PCB drawing of a 100W amplifier circuit that I had in mind for a long time, I went into practice. Darlington (TIP147 TIP142) power transistors are used in the circuit output. Ideal for active speaker system or subwoofer, guitar amplifier, home theater systems, instrument amplifier… Clone version of 100W Amplifier…
