It seems like you have a lot of energy, why not try to license the calculator from HP and build them yourself?
Does the underwhelming response indicate a lack of interest in the

Have you considered eng-tips.com. Gets a lot of traffic and I think they have an Off-Topic section unless you think you could "squeeze" into a more mainstream topic heading.
