TDA1562Q integrated with the quality and output power will be longer as popular had previously shared different applications. In this application, a 70-watt subwoofer for bass amp circuit made.
Bass TL072 opamp to control the input filter based on the frequency with potency (20Hz – 200Hz) and sound settings can be made available in the filter circuit devrelerinde different amp. PCB design quite elegant and useful resources on the eagle files provided
Car Subwoofer Amplifier
Car subwoofer 70W amplifier with active low-pass filter with adjustable cutoff frequency around 20-200Hz. The amplifier is based on the integrated circuit TDA1562 (Q) of the pump load, the power of the car installation 14.4 V. Active accommodated on a circuit board with dimensions of 8.5 cm x 5.5 cm. Low cost of implementation, simple design, a pretty good performance …

PIC24FJ64A004 cable tracer detect under ground cables
This project used PIC24FJ64A004 and Bonus Part MCP6S26. mcp2030, mcp1700 The Cable Tracer is device to detect underground cables. It was designed and tested on un-energized electric power cables but could be used on any underground cable. A 125 Khz signal is injected into the underground cable from Signal Generator.
