I’ve decided to split off all talk about my FE Goggles and Drone trap controller from my other thread because it was really specifically for the battery compartment mod. viewtopic.php?t=52406

So to cut a long story short after my made my GB1 inspired Ecto Goggles by using The Goons 3d files I wanted to make a second goggles using the knowledge (and mistakes) I learned from the first.

After printing the elements and beginning assembly I decided to pivot to the Frozen Empire variant because you don’t tend to see too many of them about. I used the shell I’d already printed to experiment with hole sizes and placements and began making some changes to The Goons design using reference images but retaining my own spin on it like the blinking red red (that isn’t screen accurate) and battery mod.

Of course you can’t have the drone goggles without the controller… so I need to make one of those too.

Unlike Afterlife’s polaroid versions, the FE goggles are actually quite similar to GB1. The changes that I’ve made to The Goons files include a larger hole on the left side in order to add a WiFi antenna. This is to be Panel mounted to the goggles via a mini coax connector to allow the antenna to screw onto it.

Image

The side knobs I’ve moved ever so slightly and then enlarged so I can install some real potentiometers there. They won’t be connected to anything but they will profile a satisfying thumb twiddle when you turn them rather than just being static glued on.

In the centre of the googles I believe is a cliplite clb300 clear lens with a black rubber washer. They are easy to find items in the uk and given so much of the propmaking was done here in England it’s more likely to be something like that than vintage American components.

Lastly underneath is a Db-15 female connector… which brings me onto the drone controller.

The connector is plugged into what I initially thought was a Saitek PX2500 which is an old aftermarket PlayStation controller from the 90s. I concluded this based on some of the images from the Sony display that I found on the ghostbusters reference library clearly show the 🔼⏺️❎⏹️ symbols on the pads.

I started modifying one of these controllers by changing the orientation of the buttons to match the source imagery and adding a toggle with red shield.

Image

After spending a ridiculous amount of time the other night trying about 4 different toggle or button types trying to work out how to mechanically fit the trigger shield to the controller without resorting to glue, designing and 3d printing various spacers and adapters and ultimately gave up at midnight. But then I lay in bed unable to sleep thinking of alternative ways. Eventually slept and woke up early Saturday morning, straight to the workshop and boom. Sorted.



I’ve wired up the LEDs but not connected them to anything yet.

I've ordered a connector which looks close enough and he’s the db-15 standard pin layout 7 on top 8 on bottom. I'd like to run power through it so that switching on the goggles also switches on 3 LEDs in the controller.

My entire circuit will be very simple. It will consist of a 6v power supply (2x cr2032 batteries), one white static LED, one white flashing LED, 1 standard red LED and 2 rectangular red LEDs. If these are run in parallel then the coin cells can power them just fine. I considered something fancy with an arduino but I don’t think it needs it.

One thing I’m not sure about is how to attach those antennas apart from big globs of glue/resin because I can't panel mount them easily with a locking nut as the shell of the controller is split in two right across the gap where they need to go. I might need to 3d print a little spacer or something. I shall experiment more.

Note the missing snapper buttons on the back bottom of the googles. On the left side the cables run from the WiFi antenna along the side and through into that hole. On the right there’s just nothing.

No yellow rubber bit on the battery compartment.

Worth bearing in mind, for anyone following this thread, is that I now believe that the images of the controller from the Sony display isn’t the screen used one and instead was a non functioning replica. But why?

Image
Image from ghostbusters reference library.

The connector seen on the underside of the googles in the movie is a gameport and it looks like there’s another cable that’s been cut by it. I think the controller used in the movie is instead the Saitek P750, a PC version of the PX2500 with a combined gameport and usb cable and just the one thumb joystick. Instead of triangle circle x square the pad is a more traditional a b c d.

I will continue to modify the original controller I bought but will keep an eye out for a p750 in the future. I usually end up making a version 2 of everything I make anyway haha.

These are some of the changes I've made to The Goons files for my own usage.

I have made the shell a little bit thicker in a couple of places. When I was bolting on the head strap the area at the top was a little thin and was beginning to warp and go that sort of white colour plastic goes under stress.

The battery compartment I'm still going to use a variant of my other design. But this time recessed slightly on the inside for better screen accuracy. I've modelled a sort of bottom that the real compartment can glue into and then be bolted to the goggles.

There is a hole for the DB-15 connector to be panel mounted.

I have moved the side knobs slightly inwards to allow me to install some panel mounted potentiometers inside. They won't have any function but will provide some nice twiddling possibilities while wearing them.

I've added a couple of oval holes to allow the decorative cables to be cable tied to the goggles themselves.

Lastly on the faceplate I added a new hole for the clip lite lens to go.

Due to the nature of my changes, many of which are very scruffy, I have no plans to release the STL files for this particular design, sorry.

I printed the new goggles shell today. However I made a little boo-boo with the placement on the print bed and it wasn’t straight. It’s unfortunately left some unsightly printing layer lines right on the front.
Image
You can see the difference in finish here between the two prints (new one on the left).

No matter. I can still use this to double check all of my other measurements and hole placements are correct.
Image

My new battery compartment holder fits perfectly.
Image

As does the rotary switch and db-15 connector.

I will utilise this print to test a few more things out and then when I am happy I will print it again (it’s about an 8 hour print and 60 metres of filament).

I won’t toss this shell though and at some point I may end up making another set of goggles to shove on Etsy.

I managed to locate a (very dirty) Saitek P750. It’s broadly the same chassis as the PX2500 with a few differences.

Image

The general colour scheme of the buttons text, symbols and joystick pad are a much more orange colour than the peach of the PX2500. The right joystick is missing as well as the little springy button that would go next to the joystick.

I’m presuming the front LEDs are also red but hard to tell at the moment. Stinks of smoke so I’ll definitely be cleaning it up even though I quite like the naturally weathered look.

Crucially that connector is most definitely correct to the movie. Looks like they just chopped off the usb part of it.

Image

I haven’t had time to open it up yet to see how it differs inside.

Woohoo! Congrats on finding the right controller--that offset cable in the strain relief is indeed a dead giveaway. Glad to find out it was a DB15 after all, too!

Best of luck with the rest of your build!

I’ve finished my first attempt at a drone controller today. I used the PX2500 with a toggle switch installed in place of the right joystick. A red LED towards the top and two types of antenna. Some decorative wiring which is unconnected to anything finishes it off.
Image
It’s not the best… but for a first attempt it’s pretty good. I’m happy with it but there’s definitely some things I’ll do differently next time.

Thanks. I think I’m the least happy with the way I’ve done the wiring but it was my first time and I was limited with what wire I had lying around as I didn’t want to buy loads of new coloured wired. It’s turned out ok though. Now I’ve got no excuse to finish the goggles though. I expect I’ll start printing them tomorrow.
