LED Lighting Driver Circuits 300V 35V

| 2022/02/27

Power LED driver Circuits made with TL494 pwm IC and MC34063 DC DC voltage converter ICs for LED Lighting. Actually there are a few more but I don’t mention them as there is no transformer information (files exist) First of all, I was interested in the LED driver circuit made with TL494 because it uses…

Electric Bicycle BLDC Motor Control Circuits 500W 1000W

| 2022/02/27

A few months ago, a friend said that the electric bicycle brain was faulty, so I said bring it and we’ll see. High power BLDC motor control documents can be useful for code repair or project development. There is also a 250w 36v electric bike motor control scheme made in China. The explanations below are…

230V 3 Phase Inverter with PFC FNA41560 PIC33FJ32MC102

| 2022/02/27

The inverter is fed from a single phase with 230V alternating voltage with a power of about 400W. The output gives a 3-phase voltage of 3x230V. Inverter diagram, dsPIC33FJ32MC102 software, Kicad PCB design are attached. Main control IC FNA41560. There is a PFC power factor correction circuit at the inverter input, which ensures that the…

12V 1AH-10AH Battery Charger Circuit (Automatic Float Charge)

| 2022/02/27

12V Battery Charger for Current Limiting Lead Acid SLA (WET, MF, AGM and JEL). The battery charging circuit SLA uses a two-step process to charge the batteries. It automatically switches to float charge mode at a constant voltage after current-limited fast charging. Float charge: slow charge, floating charge, buffer charge etc. known as. Thanks to…

BEKA-MAX Type S-EP 4 Pump Control Circuit (Clone) PIC16F628

| 2022/02/27

BEKA-MAX Type S-EP 4 pump is used for central lubrication of various mechanisms and equipment units. BEKA-MAX Since there is no IMS 559. 392 integrated in the original pump card, the author has made a clone pump control circuit using a PIC16F628 microcontroller. There is a pcb drawing prepared with the source Mplab asm and…

Battery Repair Desulfator Circuit

| 2022/02/27

@Kapibara shared the battery desulfator circuit for battery resuscitation, recovery of the dead battery, I made a similar desulfator circuit for battery repair and tested for a long time. NE555 integrated desulfator circuit warranty circuit kits have been tested by many people, but I did not want to deal with the double coil, I applied…

Protected Milliohmmeter Capacitor ESR Meter

| 2022/02/27

ESR meter is a device used to measure the equivalent series resistance (ESR) of capacitors. Built on the PIC16F690 microcontroller, the previous version uses PIC16F873A) The ESR meter circuit is very small in size and its features are very good. In the ESR Meter Milliohmmeter project, the PIC16F690 program was written in MikroC. Proteus drawing,…

PIC12F675 Police Siren Circuit Real Sound

| 2022/02/27

Siren circuit is built on the PIC12F675 microcontroller, and the outputs of the PIC12F675 are powered by a 6-transistor bridge amplifier. Considering that the resistance of the siren is 2 Ohms, the output power is about 25W. According to the author’s explanation, since the transistors in the Bridge work in switch mode, they do not…

Dark and Motion Activated LED Lamp HC-SR501 LDR Triac Relay Mosfet

| 2022/02/27

I will give information about how the HC-SR501 PIR motion sensor module works, HC-SR501 Features and its use with LDR. The HC-SR501 PIR sensor module can be used not only for security, but also for most automatically activated lighting systems, industrial automation, control areas. A few months ago, I used one of the batteries that…

Eeprom Copier Circuit

| 2022/02/22

Eeprom Copier Project with LCD display, made with PIC16F648A microcontroller, provides rapid copying of serial EEPROM memories of series 24 (with I2C protocol) without a computer. The eeprom copier can detect the type and capacity of the memory. The eeproms supported by the eeprom copy circuit; 24C00 24C01 24C02 24C04 24C08 24C16 24C32 24C64 24C128…
