I recently decided to start modding electronics, because the clear guns are just asking for an internal LED board, but I started with something much easier.

I took apart a "Magic Lights." It is a wind-up laser top.

There is a speaker that makes laser sounds, a red laser, and 4 LEDs.

My questions are:
What is the switch? Is it one of the blue things? There is no on/off switch, it just turned on when it was spun.

Is the laser even worthwhile? I know it fell off, that can be easily re-soldered, but is a laser on a Nerf gun just stupid?

That is all.

If it lit up when spun, it was probably a centrifugal switch, where a piece of metal would fly outward and contact another piece completing the circuit. Since you didn't post a picture of whatever the heck a "Magic Lights" is, I can't say for sure, but that is what is in my light up yo-yos that I had when I was a kid.

Try connecting everything, then pressing down on the tops of the blue things. If I were to hazard a guess, I would say those were the switches.

You should try another forum. That makes more sense.

Basically, without trying to sound rude, circuit building and modification is not something you can just jump right into. Some prior tuition or at least solid research is needed, along with some trial and error.

Anyways, I don't see how this is 'easier'. Wiring up LED's is one of thje simplest circuits you can create. What exactly are you trying to achieve with modification of this circuit?

You need to post a picture of both sides of the main PCB, as the side you posted has no traces on it. However as stated previosusly it's likely the blue things are the switches.

The light and sound show is controlled by the 'blob' style IC (the black blob on the LED board). Given that there are only 2 wires leading to that PCB from the 'power' PCB, it's pretty easy to deduce where the power comes from, and thus you could hook up a new power source with a rocker or push button switch very easily (as i assume you wish to trigger the lights and sounds some other way apart from spinning the gun).

If you can't work out how to do such a thing I suggest putting any dreams of electronic mods on hold, again not trying to be rude.

We're not here to do all of your thinking for you. There are other forums for that.
