Disney's stormtrooper voice changing mask


Recommended Posts

Do keep in mind that standard solder won't stick to aluminum, stainless steel or bronze wire/pads.

Your wires do look to be primarily cooper.

That soldering station looks like it should do it.

Alittle bit of flux and I'm sure it's gonna work out for you.

Success! For about 3 presses of the button, then the - came off, but that's cause I burned my finger on the bare copper as I tried to put it in place lol. But it did work, it sounded great, it was loud enough, and I love this setup.

Tinned thanks to a 45 watt iron:

And soldered thanks to the fine folks here:

Just curious, were there small holes in the circuit board where your soldering the wires?, if not you could drill (very small) holes in the centre of the soldering point, just big enough to take the wire, push the wire through the hole and solder in place, this would create a much stronger and reliable binding, if you have a dremel or similar they sometimes come with tiny drill bits that are handy for this, might help you out in this situation!  ;)

I just bought this and have gutted the electronics. I intend to mount the speaker, batteries, PCB and switch in an ABS project box to be mounted in the chest, then run the activation switch down to my palm . I've never done anything like this before so there should be interesting times ahead....

Glad this is working out.

It was pretty clear it was crossed wires.

Let me add alittle more if you don't mind.

Be very careful if you decide to drill into the pcb.

It's very easy to damage the traces.

Also, some pcb's have internal traces that can also be damaged.

A properly soldered joint should not need to go through the pcb.

 

Also, it may just be the picture, but be sure the exposed copper of your +'s and - wire are not touching.

Heat shrink tubing should be covering those exposed wires.

Remember, you only need alittle wire exposed to get a good joint.

Cover the rest.

Again, that might just be how it looks in the picture.

As far as "sealing" the board, may I recommend silicone.

The stuff you buy by the tube at home depot is fine.

Be sure it says 100% silicone.

Great seal and if you ever need to remove it for pcb work, it'll peel right off.

Please keep us informed on your progress.

Interested to see how this works out for everyone else. I've tried several types of speakers, with and without additional amps and I'm still unable to get it to sound decent.

I think it sounds great just like this. I'm getting a good clear outdoor speaking volume with no distortion. It sounds just like ANH. My audio out female plug is a 1/4 to 1/8 inch adapter, if that matters.

 

I got everything connected, reconnected, and hot-glued so now it's ready for installation into its dark round home:

I was finally able to test out the voice changer with an observer who could hear the speakers more than my voice at around 10 ft away (just on a table, not installed and not with my head in a lid). Perfect! It also has a great sounding burst when you let go.

I'll probably keep posting the installation pics here even tho I had better be done with the electronics side of things lol

Here's a short demo of the "try me" function. Gives an idea of their range when used with the Disney card, at the very least. I love that all the chatter is from ANH (albeit including "open the blast doors" from the Specisl Edition)

Awesome, great job Josh. Can you post some pics and maybe a schematic of how you have all this connected.

..me? 😅 I'll MS Paint a diagram in a sec but this and an echo fan are all that's in there.

 

"Here's the whole vocal system together. One 2 sq inch board, 3 AAAs, mini mic; no external amp or MP3 player required:

I overestimated. I can kiss the mic so it's probably 1/2" or 3/8" away. I wasn't consciously enunciating the whole video but it's much clearer when I do. The little round mic has that white plastic cover which must help with pops but idk if its tiny hole is the cause. I tried speaking really softly and it picked it up, I think my issue was being tired more than the mic being crummy 😅

I wired in a female 3.5 connector as you did, but for the mic and tested two different mic types in hopes it would help. Neither helped, always came back with a weak output. I believe the built-in amplifier just isn't robust enough for higher amplification. Heck I went so far as to add a amplifier after the PCB, still no luck, hence the reason I've been watching this thread to let someone else beat their head against the wall for a while :laugh1:  Maybe you'll have better luck.

Are you planning to extent the PtT button or just reach up under your helmet to talk? I have one of these masks and plan on using it in my Anovos kit when it arrives. But the best way to initiate voice has been a question for me.
