Foam Sponge Cutting Machine is based on HCF4093 (CD4093 can be used instead). By heating the resistance wire, which is connected to the mechanical part with the circuit, it ensures that materials such as sponge and foam are cut properly. With the VR1 potentiometer, temperature adjustment of the resistance wire can be made. BUK453 mosfet…
The FM Transmitter circuit built on the BA1404 can work with two 1.5V AA batteries. If desired, a 6 volt dc adapter can be connected. RCA Input sockets have 300-ohm and 75-ohm antenna outputs. You can stream a stereo audio signal from your CD player or other source. The signal can be received via a…
The device has S-video, Composite video outputs on the supply voltage AC 9 volt regulated circuit. Video Image Quality Enhancer and Y-C Splitter Sharpen pictures from your videotapes with this great circuit. When transferring your tapes to DVDs, it converts composite video to S-Video to ensure only capture and high-quality transmission. Video signals from an…
3 transistors are used (bc548) supply voltage is 9 volts 455kHz RF signal is produced with ceramic crystal. Description of the circuit The 455kHz Modulated Oscillator generates an amplitude modulated 455kHz carrier waveform with a 500Hz tone. You can use it to align the intermediate frequency (IF) stages of any AM broadcast or shortwave radio.…
Another example with LM3914 is sound level, water level and voltage level can be used in many applications. Sensor Used for Alcohol level measurement MG-3 The level is observed with 10 LEDs at the LM3914 outputs. Supply voltage dc 12 volt dc. Simple Alcohol Level Meter The small circuit will show you the alcohol in…
We usually see the LM3914 integrated in vu-meter circuits. In this application, it is not different. In addition to the control layer designed to monitor the water tank level with LEDs, the resistor group is connected via the tos socket for level detection. Tank Water Level Indicator Water tanks are undoubtedly a good idea. But…
Our circuit was considered little different from the usual circuit. Different from the usual operation of the CD4017 circuit. Hopefully of interest to you. They remain in one direction lights are burning and burn progressing. Lighting sequence starts from LD1. Ie, starting from the beginning after burning LD16 LD1 goes out. P1 potentiometer to set…
There is a pcb file prepared with the schema sprint layout prepared with Splan. You can download the driver file for your operating system from the ftdichip site. USB to UART converter module FT232RL Due to the fact that many modern computers do not have a COM port output (almost all modern laptops), the problem…
First on the Net diagram of a USB Hub for your computer, this assembly is being tested this page will be updated during the tests and complete assurance of that Hub. The cost is very low since you have to get only USB connectors and quartz 6 MHz (RadioSpares) for example. See the Texas site…
Ultrasonic distance meter, ultrasonic parking sensor and opamp CMOS integrated circuit representation on the board from two ultrasonic receiver circuit with LEDs used and UST-40 UST -40T Distance measurement using ultrasound is already widely used. We provide an easy to implement distance measurement and display circuit, is universally applicable. About an LED chain is the…
