3D printed Signalscope from Outer Wilds with a support to hold it standing 🪐 It's around 57cm long, and around 38cm height from the base of the support to the tip of the antenna.

I put a small lightbulb inside the middle bulb as it is the only one lighting up in the game, and it is powered and switched on from a box that holds 4 AA batteries.

There is space in the front tube to insert a Bluetooth speaker which has to fit in a 9.3cm diameter tube. If you don't care about having it doing music, I offer you the choice to have the front lens to have holes (to have music going through better) or not (music can still be heard but is muffled).

I have made custom audio tracks taken with the Signalscope for all the instruments that you can find here.
