How to Modify an existing circuit board? Answered

Using a separate on/off switch wired directly instead of that supplied with this amazon product EL Wire, ESCOLITE EL Wire Kit Neon Lights Battery .

How can I alter the circuit board to always go directly to fast strobe only? See the circuit board in this pic/video.

As you can see in the last pic, I have removed the on off switch which was set up so each time you activate it toggles between / on, slow strobe , fast strobe, & off. The switch seemed to be just an on off mechanism, am I wrong?

Amazon product is https://www.amazon.com/gp/product/B07DHM2XCN/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

I am not sure what you mean by calling this switch, "just an on off mechanism."

I mean, does that expression convey any meaning?

Well, sometimes these things are hard to desrcibe clearly.

I would describe that push button as a momentary switch, specifically the kind with contacts closed while the button is pressed, and contacts open when the button is released.

Moreover, the function of this push button, in this EL wire driving circuit, is simply to change between the different modes of EL driving.

One of those modes is a power-saving "sleep" mode.

Another way of saying that, is that, as long as the batteries are connected, this gizmo never really turns off. Even in sleep mode, it is watching (or listening? sensing somehow) the button, waiting for some button presses to command it to change to some other mode.

How to start this gizmo in just the particular mode you want?

I dunno. How many button presses are there between the "off" or "sleep" mode, and the "fast strobe" mode you want?

As far as I know, there is no easy way to get into the mechanism behind a single button interface like this.

Either you, the user, have to push the button a specific number of times, to get to the mode you want.

Or you have to build some kind of circuit to push the button for you; e.g. by wiring a transistor in parallel with the button, and then sending some generated signal, like a specific number of widely spaced pulses to the base (or gate) of that transistor, to get the transistor to turn on and off, and thus fooling the gizmo into thinking (feeling?) its button is being pressed, in the way which will kick it into the mode you want it to be in.

Another possibility is this gizmo might do something predictable when its batteries are disconnected, and then reconnected.

Does it always return to the same mode when its batteries are reconnected?

Even it does, what are the chances of that mode being the one you want?

Suffice to say, the designers of this gizmo did not consider your desire to make it easily turn on, in the exact way you want. But then, how could they know you specifically would want this?

I mean basically they wanted to pack as much functionality as they could into this thing, make it easy to use for "children of all ages," yet still build it cheaply. The result is this single-button interface: click-click-click, every time you want use it, and also more click-click-click every time you want to turn it off.

I mentioned a switch in series with the batteries right? I suppose that at least would allow you to turn the thing off quickly.

These things are like the LED flashlights/head lamps...
Instead of wasting money on a three way switch or similar, electronics do the work.
Without schematics or following the circuit traces it is next to impossible to modify them with success.
Might be easier to salvage the parts and to make a new circuit.
