250W amplifier has been tested in the field for a long time, high quality and high power. You can use it with 2 8 ohm speakers or one 4 ohm speaker in parallel. It has low harmonic distortion and high sound quality. Gain Adjustment and Technical Details Gain: This is the sensitivity to the input…
Welding machine project is a two-in-one SMPS Power Supply and Welding Machine built on the STM32F103 Development board. Welding Machine circuit Working frequency 45khz. Toroidal cores are used in power and driver. Voltage current information is displayed on the Oled LCD screen and adjustment is made with the encoder. Thanks to @devrecii for preparing the…
The lead battery activator prevents the formation of crystalline sulphate deposits on lead plates. Crystalline sulphate deposits form especially in lead batteries that have been stored for a long time, used rarely or discharged with low current. The life of the battery can be significantly extended by the desulphator device. A different design compared to…
Regulator, Power Supply I have completed the power supply, which is the second phase of the Big Breadboard project, and boxed it up. It could have been all together under the breadboard plate, but this is fine as it is, it was a very long project anyway, no need to bother anymore, it works. Power…
I gave the device in the Breadboard Box project that I shared before to my friend as a gift. He loves electronics (especially analog electronics) and since he makes lots of circuits, the Breadboard power supply system was very useful for him. I continued as before for a while. Finally, I finished my new big…
An interesting study was done using push-pull solenoids in the Arduino drum project. Rhythms are played using MIDI files with Arduino. The Arduino Ethernet card is used to read MIDI files from the SD card. 12 push-pull solenoids were used to play different sounds and the solenoids are controlled by relays. Arduino UNO – Arduino…
8-OHM RMS 100W Amplifier ZENER’s 500W version. Semi-complementary ZENER amplifier, the sound is very clean and there is no pop sound at the opening. As long as you make it with original and quality components, you can use it for heavy sounding jobs. One of the biggest advantages of this amplifier with differential torque regulation…
Active PFC supported SMPS power supply is made with IR2156 Ballast driver integrated circuit. Active PFC section uses MC33262 active power factor integrated circuit. Output voltage of SMPS circuit on load is 2X40VDC PFC output voltage is 400V There is source PCB drawing of Active PFC Power supply project (sprint layout 6) also MC33262 PFC…
Switched power supply, SMPS circuits can take a long time to repair, continuous measurements are made, electricity is supplied, re-checking, etc. When the input voltage 220VAC is cut off, there will be a voltage between 300VDC….320VDC on the DC high voltage line (in active PFC circuits, it can be 380V or higher) because the filter…
While I was thinking that there is no worse, dangerous, low-quality design for 18650 Rechargeable Li-Ion batteries and chargers, I encounter much worse chargers and batteries. The batteries of the LED Headlamp are completely dead, the charger is extremely low-quality and weak, so I placed a TP4056 module in the charger so as not to…
