So after playing around with this metal detector, I learned one thing! NOISY!!!! Wearing the headphones are horrible in this heat! On another forum, I learned that a simple LED set up to shut down the main speaker inside the housing. I took it a step further since I had to buy two LED's and 1/8" jacks. Took a Y-plug 1/4" male to 1/8" female. Plugged in the two LED's I made and now I have a set up that's nice and QUIET!!! This will be super at the beach! Since the display is already showing me whats there, I don't need all that racket!!!
All the materials can be bought at Radio Shack. The LEDs come in a two pack as well as the 1/8" stereo jacks. A 150 ohm resister was used. You can un-screw the jack housing, break off the wire holder. Solder the LED to one side and the ohm to the other. I did wrap the ohm side with a very small piece of electrical tape. This way no chance to short. Also, all jacks used were stereo, not sure if it matters. But I would used them anyways!
The big trick is to get it small enough so that you can screw the outer housing of the jack plug back on. There is also a small section from the end of the jack that I cut off to allow the LED to go through.
Here is a pic of the set up I used. This is from another forum.
Here is my pieces already put together. The right angle jack was first used, but since I had to make two I opted for the Y-plug for both LEDs.
BTW, the lights also light up different when different objects are detected. Just as the tones are different for each! The pinpointing option gets brighter as you near the object. Your already looking down at the display as you swing. This is certainly not better than the actual tones from wearing the headphones. But it sure is a lot better when its hot out.
Sorry, I just got involved with this hobby. I really don't want to get involved as making these for others. Reason being, if something doesn't work and it ruins your machine I don't want to be held accountable. Hope you understand.
These parts are all available at radio shack, its just a simple solder to the 1/8" jack. Next time I go to radio shack ill get the actual part numbers.
