Hello
Fishing is a hobby of mine and i would love to build a fishfinder. I was just woundering if anyone out there knows the steps i could take to build one. I know the basics on how sonar works and how the transducer sends and recieves signals, but im not to familiar in the circuit designs i would need for it. I have done many projects and I know a great deal of microcontroller and graphic LCD programming. And i have access to a lab for making pcb's. The only question i have is what type of transducer i would need and what type of circuits. Such as what type of transducers would i need?.. ultrasonic? audio?.. etc... so i just need a circuit for the transducer that i can hook my micorcontroller to. Also I have read about useing op-amps for the ampilfications for the high voltages used by the transducer. I have tried searching the internet and asked maby ppl but so far i havent really gotten anywere. If anyone has any suggestions that would be great. thanx
