I plan on testing the mechanism for the microphones before mounting it inside the microphone housing (I'm making up part names as I go along, it just makes it easier). No sense in putting it in there and it being wrong. I think the biggest issue will be getting the gear ratio down so the movement is much slower. The motors I'm using are around 5-8 thousand RPM and I need to figure a way of greatly reducing that, otherwise my microphones will be a blur of movement. I'm thinking using a gearing system that will slow it down, reduce it down by having a series of small gears that connect with larger ones to reduce the number of turns. Ideally it needs to be 1 turn ever 2 seconds, looking at the footage of the gigameter in gb2, it takes a second for them to separate then another second to draw together again.
I've been looking into maybe a gearbox system, you can get them on ebay such as this one

I've a few little things I need to do before I can properly mount the scan head dome into the body. I still need to attach the heat sink and cut the hole in the main body under the battery box so that the batteries can fit neatly. Once I'm done with that, I can prime, paint and get the scan dome mounted
I'll update when I can do If anyone has any ideas regarding the microphone movement please let me know, any help is greatly appreciated
The other thing I looked into was motors that spin at either 30 or 60rpm. Now I've looked carefully at the scenes where the microphones are moving and it's roughly 2 seconds for a completed cycle, thats from being together, to going apart to being together again. Now, if I had the drive spindle from the motor attached directly to the cogs for the the microphone movement then a 30rpm set up would be perfect. If I have it set up with an 3 cog resting against the two microphone cogs then I believe a 60rpm would be better. here's the two motors I've found, the only issue I think may be size.

Anyway, ON WITH THE UPDATE!
So after making the heatsink, I attached it to the body, made sure that it was positioned correctly for the dome. I then added the scan dome lip, a hoop around the opening for the dome, to the body. A pringles lid turned out to be the exact diameter and height I needed!
I then drilled and shaped the holes for the switches on the main body.
After getting some tank tread, the same tank tread as used on the slimeblower, from a friend, I added the extra detail to the front of the handle
At this point she was ready for priming!
First coat of primer, I'm really quite happy how it's looking! There's a few things I need to tidy up still, but overall the main shell is done
And here's the shell as it is now
Firstly, after looking at the new photo that's surfaced of Egon holding the gigameter, there's a noticeable lip between the top and lower portions of the shell. I had noticed that AZ Spidey had included this detail on his build and shells but it was missing on Cyland's build and very difficult to see if it was there on the screen grabs and in the film. I cut out the lip using styrene, wow, what a difference it makes. It really tidies up the shell and makes the lines that much crisper
I suppose the biggest update would be that I fitted the LEDs into the microphones! This was far more fiddly than I anticipated. The 5mm LEDs were to big to just push up into the microphone head so I had to cut them off. I then threaded the ribbon cable through and soldered 3mm ultra bright orange LEDs in their place. Once all soldered and properly insulated with heat shrink tubing, it was just a matter of pushing them into position.
As you can see, it's a bit of a rat's nest of wiring in there at the moment, it's going to be all tidied up before I finally close it up though
And here's a video of it in action enjoy!
And I have been mega busy!
First of all, now that the main shell is finished I decided to paint it, went with metallic black, has metallic flecks in the paint, the same as the PKE
I've also started afresh with the microphone housing, not complete yet but definitely coming along very nicely
BUUUUUUUUUUT I suppose the biggest update would be....this
Since filming the video I've rearranged the gears and the noise is greatly reduced. My dad is going to bring me some grease to lubricate the gears, further reducing the noise. Let me tell you, getting the mechanism right was a real pain in the ass, very fiddly and precise.
So what's left to do? Well I have to finish off the microphone housing and fix the dome in place, a bit of painting but that's about it, it's probably going to be finished by next week
For anyone reading this thread, I've had a closer look at this build and can tell you it is awesome. Luke's attention to detail is amazing in making this a great giga meter.
Keep it up Luke.
Yes we've collaborated on it and the mechanism used will be the same, however the builds of each shell will be different.

And a little side by side comparison with the PKE meter. You can see it's not much bigger in length, the camera and angle in the film really do make it look so much more larger. Weight wise, it's slightly heavier than the Matty PKE, but not by much.
