29 delightful retro gadgets that will make you nostalgic for old-school technology

Ever since Sebastian P. was a young kid, he's been obsessed with gadgets and electronics, especially those that made sounds.

"I used to have countless gadgets and toys that made blips and bleeps, and recorded them with a little Fisher Price toy cassette recorder," he tells Business Insider. "Later, in my early teen years, I really got into video games, synthesizers, and music in general."

Sebastian has turned that passion into a fascinating Instagram account that unearths retro gadgets and shares bits of history about them. To date, he's shared almost 1,000 posts on his Instagram, nightliquid retro.inc. The posts cover design curiosities from the 60s, 70s, 80s, and 90s, and Sebastian says some of his favorites are the obscure ones people haven't heard of.

"Many of them cost a fortune and are almost impossible to find on the secondhand market," he says. "It's funny to think of why they're often worth so much today. Most of them simply weren't successful back in the day, and nobody bought them."

Sebastian has pulled together 29 of his favorite gadgets, from a drum machine watch to early Apple masterpieces.
