My problem is that most of what I do is covered by Non-Disclosure Agreements (NDA's). In the past month I have:
Designed a new fecal matter collection, dilution, and dispense system. I can't go into details, but you can imagine the bad jokes being made as I worked on it.
Designed and prototyped an automated assembly system to make the aforementioned fecal matter unit (750,000 units/shift/year).
Designed and prototyped a new electro-hydraulic system for testing artificial heart valves (500,000,000 cycle test).
Designed, built, and tested a system to measure the deflection of electric guitar bodies in bending and impact.
Designed, prototyped, and tested a new linkage system for providing variable frequency & stroke to an hydraulic cylinder.
I am currently working on a set of machine stations that take bulk parts for an assembly, orient them for assembly, and load them into carriers such that a pick-and-place system can insert them to create the overall assembly. If all goes well, I will get the contract to do the actual assembly of the parts sometime about the first of next year.
I tend to "lurk" as I really can't go into details about most of the things I do. My customers would get more than a bit irate were they to find specific information of my work for them floating around cyberspace.
