Just because you have old electronics collecting dust, doesn’t mean you should simply recycle them by dropping them off at the recycling center. If you’re proficient in electrical work, you can wire old electronics together in a very creative way. You can literally make your electronic junk sing for you!
Star wars’ Imperial March played by old floppy drives:
Eye of the tiger
Gotye - Somebody That I Used to Know
The Animals - House of the Rising Sun
But if you lack the necessary skills to replicate the above, you can always do what I do and use your old computer as a door stop. Just kidding!
