Hart hihat 2nd bonus piezo found, how should I connect it? Advise please!

[flipotto]

Hi all,
So I have a Hart hihat (slice of pizza looking 1/4 circle) trigger pad.

My module is a td-3.
I currently get one sound out of it, I was hoping to get the edge sound and thought of adding a second piezo.

The jack was loose so I thought I would dive in to fix that and check things out.

I open it up, and no surprises, there was the piezo and the TRS jack with a circuit board.

However, when I lifted out the board, to resolder the jack…

There was a second piezo not attached to anything!

My first thought, when looking at this was, they must have it pushing up against the solder spots on the board to the solder spots on the second piezo.

However, upon closer inspection… they won’t line up, this second piezo is not attached to anything.

So can someone please advise me how to connect this to get a 2nd zone?
I have confirmed the wiring on the 1st piezo.
TRS jack connection –
hot (center conductor from 1st piezo) to Tip;
(outside circle on piezo) to Ring and Sleeve.

How should I wire the second piezo in?
Will these two piezos be too close to each other?

Again, this is for a TD-3.

Thanks in advance, for any help.

Success!

I moved the large piezo to the outside of the case, near the edge.
Double sided taped it to bottom near the edge.
Rewired according to beatnik!
I now have a hihat, 2 zone.
I changed the pad type to cy on the td-3.
Some minor adjustments to come. Now I get bow and edge sounds based one where I hit.
I can’t wait for my piezos to come in the mail.
Next up add a second zone to the hart ecymbal 14″ crash to become a ride cymbal with bow and edge and bell on velocity hit.

Then a second zone for the hart 12″ crash to allow edge and bow.
Then create a third cymbal for the crash3.

Well, I was going to say that there was a good chance that they would be to close together and that you would probably end up triggering both of them, but it sounds like you got it covered. Congrats!

Hey Jman,
I am still working with the sensitvity..
However, I did move the large piezo to the outside of the box, about an inch from the edge of the bottom of the ecymbal.
It is working pretty good, I still need to get used to when the edge will trigger.
Also the jack inside there is very very cheap… I had to repair that is several places, I really need to just buy a new jack, and get rid of the circuit board.

From the looks of it you should be able to do that fairly easily. That’s a pretty small area to get the triggers to work separately. Hope you get it dialed in. The larger piezo will usually be more sensitive than the smaller ones, so I would put that on the location that you will be striking most often. You should be able to remove that jack from the board and solder your wires directly to it.
