Neat-I'd seen a couple of those before, and maybe I'll try that AIQ one. I've never been a huge fan of the topper that's just the name of the game again though. For something like whitewater it makes sense (no name on the translite), but in most cases it's just a little redundant. The one thing I was thinking of there was a second infinity gauntlet (maybe the Iron Man one from Endgame) with the gem LEDs wired opposite to the Thanos gauntlet in the game (so they'd light up as you collected them). I think that's how the official $1000 topper behaves, but that also has a node board in it, so I don't think it'd be possible to trick the game into thinking it was present.

This is pretty cool, but I'll admit I have no idea how to get 7 degrees out of this? How do you read a bubble level?
The base has the 7 degree slope built into it, so when the bubble is in the center your playfield is at 7 degrees. These levels only have like 2 degrees of range in them so you have to print it to sit at the angle you want.

I assumed you use this STL for the battery mod above

I started with that but ended up redesigning the file. I didn't like the the thread depth for the machine screws and the file had the holes threaded but I found that the screws easier to start, the part less prone to split and had better bite just self tapping into the plastic by simply chamfering clean holes, The build up height was set to be a good fit with a metal washer, eyelet and the screw to match a AA's length. I also brought the flat face that's there for ease of printing up so it can be installed either way around. This is important because some games were top right + and bottom left - with others it was reversed on the PCB. With these changes all went together well, held together tightly and didn't split using PLA with 20% infill.

If you're looking for a way to install 2 x 4" speakers in a WPC display panel I've drawn these up in CAD and made stl's available. Basically it sets the speakers back and mounts a 4" in place of the tweeter on the right thereby not requiring the panel to be cut so it can be returned to original configuration. I did this in preparation for a stereo sound board upgrade which would benefit from it producing output from a couple of 4's on their own channels. https://www.thingiverse.com/thing:5191988

Thanks for sharing and what else is involved in switching in two 4" speakers in a WPC to improve the sound?

I'm waiting on a Tilt!Audio board to arrive so I can assemble it. I've already set up the software and configured an RPi with the OS img then added stock and custom sound files. The software has it's own webserver and GUI so once configured using the RPi WiFi I can set it to my own routers domain to access all it's functions and upload customizations through anything running on my LAN. It's pretty straight forward and so far the software seems pretty slick but I'm not a huge fan of Lua if I want to customize some of the software beyond what it presently offers which is enough for most requirements.

So circling back to the speakers the board has separate channels for left, right and sub as are the audio samples it renders. This requires removal of the wires from the right speaker which are currently just in parallel to the left and relocation back in isolation to the audio header of the board. To play right channel to a choked tweeter isn't going to provide the range of sound the channels will be producing. The most efficient way to approach this is to replace the arrangement with 2 x 4" coaxial speakers with internal crossovers.

Sample audio from TZ. (installer screwed up naming one of the .ogg files oops)

Your STL link is broken and would like to download and try this out. Thanks.

I just downloaded it from the link under the files tab from thingiverse. Maybe thingiverse is messed up att. It's notorious for having issues. I would attach it here but it doesn't meet with the file types allowed. I posted it to a github repo of mine to help you out. https://github.com/necro-nemesis/Space-Cadet-Pinball-Raspberry-deb

BTW I created a Space Cadet Pinball Debian package including desktop entry then compiled it for Arm to run on Raspberry Pi OS. The deb is in releases for anyone wanting to add the old Windows game to their pi for nostalgic reasons. Arch is Arm so don't be trying to run it on x86_64. The stl file is in that repo. ;)

I've deleted the file from github to clean up the repo. If you still require it advise. I can create an additional repo for pinball related if file sharing appears to be a requirement. I have a several projects on the go so I like to keep things somewhat organized. The benefit of github is the ability to track changes which helps me keep my thoughts straight with all those. That and it's part of a CI compiler/packager I write code and packages for so it's also it's automation I use regularly. For straight file download someone doesn't need to be conversant with github.
