Build a Frequency Divider (crossover)

| 2019/06/12

To reproduce the audible bandwidth, three speakers must be used to complete the audible spectrum, since a single speaker can not emit the frequencies; Between 20 hertz and 20,000 hertz, this audible band is divided into three speakers, like this: Woofer – Responds to low frequencies. Medium (MidRange) – responds to mid frequencies. Tweeter –…

Make Aluminum Amplifier Box

| 2019/03/29

Making an Amplifier is sometimes very challenging in the Amplifier. It is important for us to use easy-to-process material for the amplifier box, because the indicator, fan and so on. In order to have a fine workmanship for the sections, there is usually no equipment and materials suitable for these jobs in the amateur workshop.…

Dual LCD Voltmeter Ammeter 0.100 VDC 0.10 A DC ATMEGA8

| 2019/03/29

The dual channel amp volt meter circuit allows simultaneous measurement of 2 DC voltages and 2 currents on the LCD screen. Voltage measurement: 0-100 VDC or 0-10 VDC, Current measurement range 0-10A or 0-1A. The operating voltage of the circuit is between 8v-30v DC and does not require calibration. The heart of the meter is…

0-30V 10A Power Supply Circuit LM723 TIP3055

0-30V 0-10A laboratory type adjustable power supply I mentioned in the article of the relay bypass circuit for regulated power supplies, the K7200 kit version is 1/1 clone There is almost no difference except a few changes in PCB design and the use of 6 power transistors. LM723 amplifiers were used at the control level…

IR2161 SMPS Circuit IR2153 Alternative

| 2018/06/10

I’ve shared a lot of SMPS power supply projects with IR2153, especially AT, ATX power supply. The IR2153 works great for evaluating power transformers. Even bigger companies such as Yamaha have used the 8 pin MOSFET driver integration in their products. an integrated but not very common use in DIY environment I did not have…
