The post whore thread.

You have socks?

Socks & shoes! (I know, riiiight)
The secret is I put electrical tape on the soles to keep them from showing wear, then he doesnt lock them up too.

Ummmm.... what have I missed?

It's PWT, not much to miss.

[ChickNorris]

Acoustic excitation produced by jet-engine effluxes was simulated in a progressive wave tube (PWT) facility with a computer-based control system. The PWT siren is driven by a signal generated numerically in a PC and then converted into analog form. Characteristics of the acoustic pressure measured by a microphone are analyzed in digital form and compared with those prescribed for simulation. Divergence is compensated by immediate modification of the driving signal and this action is repeated in the form of iterative process until the test specification is attained. Typical power spectral density (PSD) shapes with maxima at low and high frequencies were simulated. A "tailoring" approach has been also achieved when a test specification was determined directly from field measurements for the particular aircraft under consideration. Since acoustic pressure signals of high level differ from the Gaussian random process model, particularly in terms of asymmetric probability density function, a method has been developed to make the driving signal also non-Gaussian by simulating skewness and kurtosis parameters of the APWT acoustic excitation simultaneously with PSD control.

Look Pa! It's wiggling again!

Don't. Priority mail them to me.

Pm your addy. 1 dozen

Usullay that happens when you fiddle with it

I'm trying to figure out how to get a video from my phone so I can post it.

Electronico bullshit is getting in the way, it's my first attempt, …..I might figure it out before the weekend is over.

[OtterbatHellcat]

I'm going to find something else to do....mostly because a hammer is too easily obtainable at this particular junction.
