A simple led animation (flip flop) circuit with NE555 Timer IC. You can adjust the flashing speed and brightness of the LEDs with the tirimpots on the circuit. There is a pcb drawing of the circuit. You can arrange the leds according to the shape you want. The supply voltage of the circuit should be…
Siliconchip shared for free on the site where one of the projects sold stock fitters use a little more of a detector device is simple, inexpensive version can be called at short-range metal detector. In-wall cables are used to find metals known within the walls of electricity, water and so on. There are systems in…
two different circuits happen to have 555 timer integrated with the structures and mc 34063 switching control integrated with the circuit used in the transformer television or monitor EHT transformer originally intended use in car air filter, carburetor something to do with the car but know much about because I have not figured business people…
An interesting circuit transformer core DC12 volts to DC24 volts dc upgrades have been made obsolete n555 number 3 connected to the output end 2sj302 MOSFETs with opto-up Kubla circuit charging source is being used to supply power can give 1.5 to 2 amps In response to the output diode by399 can use 4N25 opto…
Lamp Flasher Circuit NE555 integrated control of 220 volt mains supply for over-current through the resistor capacitor and so on. taken with passive elements so no need to use a transformer to supply RV1 and RV2 brightness of the lamp flashing speed can adjust the lamp power used to control the triac (bt136 bt139 available)…
A simple useful Power control circuit can be used for 12v lamp dimming dimmer or motor 12 volt motor speed control. In the circuit diagram, the driver appears as integrated 7555, don’t be fooled, you can use the 555 timer IC. This integrated is produced by many companies. There may be name differences. It seems…
555 demonstrate the use of integrated square wave oscillator circuit on a simple counter and Proteus simulation drawings. 0-99 counter circuit (you can set the count rate with variable resistor RV1) 10 Led king circuit rider (you can set the speed of light LEDs with a resistor RV2) 29 Led Animation circuit (resistors RV1 with…
There is a mouse repellent circuit project circuit diagram and eagle pcb drawings based on op-amp cmos tll integrateds. Thank you to the contributors Working Image of the mouse repellent circuit Ultrasonic Mouse Repeller Circuit diagram and Completed State Integrated and Transistors Used in the Circuit Integrates CD4017 CD4013 NE555 CA3130 Transistors BD139 BD140 ULTRASONIC…
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…
Circuit made a long time ago and has been tested. There were a problem in the operation and construction. We must do BDX53 your engine is larger output transistors. 5 and 6 pin motors can be run with the circuit. Four-ended output transistor to run the engine to be increased. So four BC327 should be…
