Re: [DIYbio] Electronic requirements for redesign of Arduino PCR thermal cycler

I think that based on how much more complicated it would be to add an adequate heated lid (at a constant ~100degC), I'll probably go for a design that works by convection cooling as described in this paper (http://www.biotechniques.com/BiotechniquesJournal/2011/January/Rapid-DNA-amplification-in-a-capillary-tube-by-natural-convection-with-a-single-isothermal-heater/biotechniques-307538.html).

Since not having a heated lid would mean I'd be using paraffin wax/oil anyway, it wouldn't be that much of a change and the technique looks interesting.

I'll probably use the same design as in the original instructables article I linked to but change the depth of holes in the aluminum heating block.

Hopefully it will be easy to change the programming code to just keep the block heated to 95degC, and remove the fan.
