Another test for "engineerness" is if you like "Office Space". SWMBO thinks it's the dumbest movie ever; all the engineers I know love it.

Office Space and Dilbert are fantastic. It's scary how similar work can be to Dilbert...

I just finished the board layout for a really cool O2 sensor tonight. It will measure the O2 concentration using light. I bounce red light off a tablet that contains a powder that fluoresces. There is a very small time lag (nanoseconds) between when the red light hits the tablet and when it floresces. I blast the tablet with a high-frequency sine wave then use FFT (fast fourier transform) to measure the lag in response. This lag is proportional to the amount of O2 where the tablet is.

The cool thing is that it can be used in liquid, so works with beer! Once I get it working I'll watch the O2 deplete in my carboy during fermentation. Can't wait.

Works! It reads the O2 concentration inside the pink pipe shown there. The graph shown is room air, then the tube flushed with Nitrogen, then room air again. 21%. Woot.

I did 2.5 years of ME before I realized I wasnt very good at Calculus.

However I did get my degree in Logistics and Supply Chain Management, which is kind of like "engineering for business". Been in retail merchandising/supply ever since.

Engineering jokes?

A half glass of water would be described by an optimist as being half full, a pessimist as half empty, and by an engineer as being in a container twice as large as necessary.
