Just starting a thread to track the admittedly minor mods I've made to my Spirit Halloween PKE meter, which I bought in 2021 for about $30.

Side note, apparently Spirit has a new version of the PKE that is selling in some areas (some in Canada, for sure), which has been been considerably redesigned inside. (all new electronic boards many mods no longer work and a lot more annoying to get to screen, incorrect green instead of yellow LEDs on the arms, plus it has a newly squared off handle, closer to the Matty PKE appearance). On the other hand, I bought one in Los Angeles at a Spirit Halloween retail shop a week ago, and it's exactly the same as mine, so I'm not clear if there's just a lot of old stock they're still working through, or if I got lucky, so who knows.

Image

My mods consisted of a full repaint, plus an upgrade kit with belt clip removal (replacement plug), and added buttons, and a 3D printed screen replacement. Kit came from "Epically Geeky" on Etsy, and I think was about $20, at the time (I got the green screen with dark green lines):

Fair warning, this kit may not work well with the newest iteration of the Spirit PKE, unless they've updated it? I saw someone try to install one just recently on these new models, and it went... well, kinda ok at best, but far from ideal, and with a high amount of effort.

Step one, open 'er up! 6 easy screws.

Image

First thing to go was definitely the belt clip stud. Lopped off the bulk of it pretty easily with my Dremel's cutting wheel.

Image

The hole left has a raised ring around where the stud was, so it needs to be enlarged a little to eliminate that ring.

Image

... aiming for a hole that the 3D printed plug will go into.

Image

The printed plug had a little notch on one side for easier alignment, when you see it from the inside.

Image

It's clearly not a perfect fit, though, so cleaning it all up takes some work.

Image

Image

I taped the plug in place, inside, first.

Image

Continuing the disassembly and electronics, the middle arm/gear assembly lifted out pretty easily, and had two connectors to the board, plus some wires. Everything must be disconnected! (pro tip: label your connectors... this wasn't bad, but the newer models have a lot more wiring inside, oddly)

Image

Image

The boards are all attached, as you can see, by welding them in place (by which I mean melting plastic posts and turning them into "welds"). Have to grind the plastic away or melt it off with a soldering iron or similar until the boards can be lifted free.

Image

Underneath is the light sheild (which only allows the LEDs to light a small circle on screen) and under that is the actual screen.

Image

Image

The kit I bought replaces the screen part (with a more accurate gridded screen) but not the buttons, which are part of the OEM screen piece, so those need to be cut off. Dremel cutting wheel made short work of it.

Image

Image

The OEM buttons need a light shield in this configuration, so a little bit of aluminum foil works great over them. (recommended by the kit maker)

Image

The screens holes needed to be widened slightly, but otherwise it just dropped over the same pegs the original had used.

Image

No foil on the button edge:

Image

With foil:

Image

Functionality verified, the board will just be held back in place with hot glue (instead of the melted plastic posts). Nice and easy.

Image

But first, the outside needs to be painted, while everything is still apart.

So out comes the Bondo All Purpose Putty. I'm not a huge Bondo fan and find it obnoxious to work with, but it did seem like a decent option for this application.

Image

Some sanding and smoothing later, things are looking a lot better. I didn't get the angle 100% perfect on the plug... that's tougher than it seemed, apparently. (And yes, it annoys me to this day, but... eh)

Image

Image

Once painted, though, it's ... tolerable. Just. LOL. Maybe I'll redo it someday, but I kinda doubt it. #Lazy

Image

Image

I laid down a silver layer on the top of the shell, after the primer, to aid in future weathering.

Image

Image

I hit the new buttons, too, while I was at it. (and sanded them a touch)

Image

I masked off the thumbwheel (I think it is?) below the screen and kept it silver, as that seemed more accurate. Definitely adds more visual interest than the all black stock coloring. A couple scratches of "natural weathering" show the silver underlayer was a good idea LOL

Image

The final back looks ok, enough.

Image

And I'm pretty darned pleased with the final result, once I got it all back together (and added a little light weathering):

Image

For carrying, while perhaps it's not completely screen accurate, I really wanted a holster. So I picked up a cheap tape measure conversion on eBay for a modest price. Not as fancy as the custom one, but hey, it was under $20, so I can live with that. If I ever want something fancier maybe I'll make something myself.

Image

PKE looks fine in it. (Pic taken before my mods, clearly)

Image

And that's it for phase one! Quite pleased with the outcome, frankly.

My next project is the motor mod. I'll document that as soon as I get it done.

One of these days I might undertake the mod where the arm LEDs are rearranged into the right sequence for GB1 (from the inside out: 3, 5, 7, 4, 1, 6, 2), but that feels a little more risky than this was, and given that this version is no longer available, that's a little scary...

Quick update:

As I mentioned in an edit to my OP above, I purchased another PKE meter last week, over the counter at a Spirit retail shop in Los Angeles. Exactly the same as mine... I popped it open to be sure. Yellow LEDs on the arms, too.

Image

Image

I discovered different screen mod that is sold by Freeky Geeky (the website store is down now but I'll add a link later) and looks interesting... but (a good but) you don't need to change out the OEM screen with the kit I purchased for my last one, for his mod... it overlays the stock screen. I still want the little silver buttons and still need a plug to fill in the back hole, so I happened to be browsing around Thingiverse, and saw:

https://www.thingiverse.com/thing:3870303

This appears to be the *exact* same stuff as the Etsy kit I bought, so I actually think they're just selling the models you can print yourself for a lot less... if you have a printer, and if you already own the right filament, and know how to do multicolor prints, etc. So you might be able to print your own for less. (And then there's the moral issue of selling non-commercial license prints of Thingiverse models, but everyone can make their own call on that)

But anyway, for modding my new PKE, I'll use the FreekyGeeky screen and print the extra bits (buttons and back plug) myself this time.

I need to paint the thing first, and have a vacation coming up, so it may be close to Halloween before I have time to pick this up again, but I wanted to get this info down. :)

Too many other projects have prevented me from really tearing into this project.

BUT I did get FreekyGeeky's screen upgrades in hand, and I have to say I absolutely love them. Definitely need to convert my main PKE over... tear it down again, pull out the 3D printed screen, put the OEM screen back in, and button it back up. Then I can install the FG screen on top.

The two screens come nicely covered in protective plastic, so they're nice and shiny when you peel it off.

Image

Fair warning, the grid side is bit of a PITA to remove, since each of those tiny squares is separate. Use your fingernail to gently scratch it all off (ideally without scratching the acrylic). Hit it with some IPA when you're done so it's nice and clean.

Image

FG offers to sell them to you pre-weathered if you really want (for a fee), but yeesh. One drop of cheap acrylic, wipe it off with a napkin, and the paint stays only in the cut lines, where you want it, and you're done.

Image

Image

The little panel then *literally* snaps right into place, no tools or prep needed. Gives the proper angled screen look from the originals!

Image

And the grid lines show nicely when it's on.

Image

Probably the easiest mod I've done in the long time, and what a difference!

It'll be interesting to see if this ends up in a drawer once the HasLabs PKE comes in, but what a shame, if it does, because these are great. :)
