[DIYbio] Re: Designing a DIY Gene Electroporator

Ahh, I found some cheap caps ($10) that are close to brand new and not
going away any time soon as far as I can tell. Keywords: microwave
capacitor.

On Ebay I was seeing ~2kv ~1uF caps for $10, they're much larger than
that MOSFET electroporator's 'energy storage capacitor' though...
which he only lists as 3.5kV 5uF, which doesn't give me any decent
results on google.
