DC-DC converter, the heart of the Gel Power Supply

Sourcing this part is critical to being able to continue to sell GelIS.  Unfortunately there is an incredibly long lead time on these parts, as they come from China.  My strategy is to generate a few orders for the box, and then order extras far far in advance.  I hope it works!  If the rate of orders keeps up, I should be ok, but otherwise delays could happen!  I will have to think carefully about this.
