No, but I'd argue for a different reason than lack of resources.

I'd argue that it's simply not possible to "scratch an itch" in biology.

For mechanical and electrical engineering, there are projects that intersect with hobbies that people want to do and can do with the right equipment.

For biology, I'm not sure that I can really cough up anything interesting that intersects with many hobbies.

Craft brewing? Maybe? But that sure doesn't require much high tech equipment.

There are a few blog posts about this: http://www.badscience.net/category/mrsa/

The reason garage labs produce less than real labs, is more likely due to selection effects. The majority of people passionate about biology probably try to become professional biologists. The people doing experiments in their garages are those who didn't make it, or people totally outside the field. And there's also fewer of them.

That's not to say if you took all the actual biologists and make them work in a garage, they wouldn't produce interesting things.
