I designed a small printed circuit board for this mod, I don't drive anything directly off of the LEDs because it would make the LED driving the beeper dimmer than the rest of them. You would have to install the P.C. Board to get it to work.
@cincyghosthunter I was also curious if an extendable ant. probe could be fabricated into the k2s main circuit board or if you'd have to make a circuit board for that also.And the circuit board for the beeper.Is that something I could get from you?
@GHOSTOFTN I'm not sure if you could attach an extendable to one of these. I thing the antenna is a part of the circuit board. Yes, you can get the beeper circuit board from me. I made a bunch of them and have a few left.
No, I designed a tiny circuit board that fits into the K 2, the parts go one one side, the beeper on the other side. Then you pick which LED you want to trigger the beeper, solder the power, ground and signal wires( to the IC chip) for the proper LED and there you have it. I discovered that a mini speaker would generate it's own EMF and keep the meter falsing and going off so I used a special piezo beeper that emits no EMF. You can't drive the beeper directly because it would make the LED dim.
Hello can you post an instructional video on how to do this mod because it would be very helpful instead of staring at the LED's all night.

how did you add the beeper? did you attach a mini speaker to each one of the led's?
