Watch a rusted flea-market lamp get lovingly restored

"In this video I'm restoring an old French Wonder lamp," writes MyMechanics (Patreon). "My good friend TysyTube Restoration bought this Wonder lamp on a flea market in Paris. He asked me if I want to restore it and obviously I said yes. He already restored two of them himself, I link his videos and channel below. These Wonder lamps are very well known in France, they're used on railroads mostly as far as I know."

I want to put a Raspberry Pi in one of these and I don't know why.
