Microphone preamplifier circuit 5 volts to 20 volts dc voltage is working with measurements, operating characteristics quite well Circuit AD8648-ARZ SMD Op-amp based on the printed circuit board design is very good as is the practice of aluminum cans for supply and 9v alkaline is used very good results. Preamplifier Circuit 0-014% power supply 5v…20V DC

GPS Circuit Boats Computer PIC18F4550 Microcontroller
Generally known as PC Tools has prepared a project 🙂 but siliconship in the boat’s GPS system tracks the GPS module EM 408 and mikrodenetleric pic18f4550 usb connection to the circuit there also. 2X16 LCD Indicative date, etc. on the location of the clock compass. Viewing a lot of information. GPS circuit does not include the source code of the software given hex ​​code but with PIC18F4550 circuit design, details can inspire people interested in programming this reason, I wanted to share
