I’m guessing adafruit or arduino, which controls the up and down motion?DerGrundel wrote: ↑April 2nd, 2019, 2:24 pm I like that new way of driving the arms.

Also, would there be thoughts to getting these pieces made in aluminum? Or maybe resin cast?
My plan for this project is to have everything 3D printable. I don't have access to an end mill or CNC so I wanted to keep it simple.
I have been documenting things here:
As far as your light solution this will work directly with the pca9685 servo board:
https://www.amazon.com/Controlled-Recei ... WXBMY2HT0C
The elechawk rc switch is a Chinese made unit that I have yet to find one made locally here in the United States. 40 degrees is off and 110 degrees is on. The above link to the amazon product is the form you want.
But that aside if you want help on the coding piece I am game.
And more specifically I was looking for 3-d stl files of the knobs to finish out the print I have from your cad link.
The servo idea with the mechanicals is spot on. Though on my builds I have been moving more towards a belt mounted battery setup using dewalt batterys with a usb phone charger adapter. It makes addressing power needs much easier and more manageable.

I've always loved the RGB PKE Meter and I can't wait to see this project completed.Honestly, I could use a ton of help finding episodes that have both good shots of the screen for graphics and good clean sound samples for each of the PKE meter states. I've located a couple but a majority of scenes have background noise or something that makes it hard to get a good looping sound effect.
If you need any help identifying all the main variant screens from the cartoon, I think I could recap them with some gif, then you can choose wich ones you want to include in your project.
I am going to try and get things even more compact inside. I try to stick with off the shelf solutions so others can more easily follow. Fabricating your own custom doodads, creates its own set of issues when things break.
According to this it might be possible to add a text overlay to the screen itself:

The sense hat takes up a substantial amount of space in the unit. Without the sensehat and just doing straight text injection based on input, It would be possible to use an HDMI display and then you would be able to separate out the audio signal.
The kicker is you have to find a 3.5" hdmi display panel. The ntsc board works, but removes the ability to play sound as it is tied into the hdmi port which gets disabled when you switch to composite rca style display connector types.
And this one may work:

I hate having to order out of China. I can not find anything like this domestically...
