Hang in there, buddy! Give the SKTC idea a try. Your frustrated as any of us would be. Walk away from it for a week or two then come back to it. Don't lose sight of the fact that you are a G-damn genius! If it can be done, you can do it. Keep it yours. If you can't tolerate it any longer open it...
Hugo, do you or would you consider selling some of your pumps? It is said that the test of another's intelligence is the extent to which they agree with you. I have a similar idea for a headlamp that needs a tiny pump like yours to function.
