Failing Pokemon Pinball: Battery Free Rumble Mod Gone Wrong

I try to discover a way to power Pokemon Pinballs rumble feature without the need for an additional battery.
I use the wrong soldering tip for the job I get the voltage wrong and I barely understand how electricity works.
Come cringe as I solder things into the gameboy cartridge with it still in the shell.
Overall probably some of my best work. Items from the video: Step Down Converter: Tweezers: Thicker Stranded Wire: Solid Core Wire: Thinner Stranded Wire: Multimeter Test Leads: Multimeter Tweezer Leads: Multimeter: Soldering Iron: Blue Solder Mat: More original mod concepts coming very soon!
