I finally got around to finishing my ecto goggles! I used Mike's build thread as inspiration: viewtopic.php?t=50521

Most of the parts are from the GBFans shop except for the face pad, rotary switch & knob which I got from eBay.

Decals are from LastTakeMedia on Etsy: https://www.etsy.com/listing/1572957578 ... l-stickers




I knew I wanted those goofy green LEDs and sound effects in this thing. So I found a small sound module on Amazon: https://www.amazon.com/gp/product/B0C491SSSK/

You can load whatever audio file you want via the USB cable, and trigger it with the input button. Nice and simple! It also charges via USB.

I wanted to have the rotary switch power everything on, but I also wanted the option to disable the sound module since it can get annoying. To do this, I soldered my own toggle switch to the tiny terminals of the existing power switch & mounted it on the outside. I just had to slightly widen one of the existing holes in the goggle frames. Then I snipped the connector from the button & wired it onto the rotary switch. This way, when the rotary switch is turned on, the sound will only play if the toggle switch is also enabled. Lastly, I split off the battery wires so they'd send power to both the module and my green LEDs, which get switched on/off by the other side of the rotary switch.

(Pro tip: if you're bad at figuring out what resistors you need for your LEDs, consult ChatGPT. I gave it the voltage of my battery & the voltage rating of my LEDs and it told me to wire them in parallel with 35 ohm resistors. What a terrifyingly incredible tool.)

I used small pre-crimped JST connectors to make it easier to connect everything together, instead of having a big nest of committed soldered wires. Bought then from tayda electronics. Probably my favorite place to order components. Highly recommended.



The module sits perfectly behind the face padding. It kinda just stays in place which is nice.


Here's a video showing of the electronics in action:

I basically took the beeping sound directly from the movie & used an EQ to filter out the music, leaving just the beeps & the whirring mechanical sounds. If anyone wants it I can upload it somewhere. It is annoying though. There are probably cooler sounds you could use haha. If you end up trying this yourself I'd love to see it!
