Do-it-yourself E(K/C)G Kit

It’s pretty difficult to make an ECG, at least if you’re not an electronics expert. Everyone in my electronics lab during undergrad had trouble with theirs.

Nonetheless, if you’d like to try making one, this do-it-yourself kit (via medGadget) should help.

I can’t see too many uses for this besides watching your own signals, but who knows. Be creative.
