FranLab is that rare YouTube gem: genuinely educational, zero toxicity, and run by someone who clearly loves what she does. Fran Blanche is a self-taught electronics engineer who takes you inside her workshop to rebuild historical automatons, design boutique guitar pedals, and restore vintage space-program hardware—all with warm, accessible explanations.

This isn't dumbed-down STEM content. It's real engineering presented by someone who wants you to understand how things actually work. The pacing is calm, almost meditative, which means it won't compete with Mr. Beast for your kid's attention—but that's the point. If your teen has ever been curious about circuits, soldering, or how music gear works, this is gold.

The elephant in the room: it's still YouTube, and even the best channels live inside an ecosystem designed to keep you scrolling. But if you're going to let your kid watch YouTube anyway, FranLab is about as good as it gets—educational, inspiring, and a great example of someone who turned curiosity into expertise.
