Macrofab Engineering Podcast

Podcast Notes Continuing from last weeks discussion of the two conference room names at MacroFab HQ. Emmett Naughton on twitter says: Conference Room A: The Hertz Locker and Confernece Room B: The Thunder Ohm. Parker is making plaques for the conference room doors now out of PCBs. Space Echo Update! Last week Parker and Stephen asked for some clarification on some old school audio measurements so they could calibrate the Space Echo. Steve Kuehn a self proclaimed gray beard from Austin says the following. 0 dBm in the audio business refers to voltage level that will produce 1milliWatt into a 600 ohm load. But over the years, it refers to a voltage level even if you are not aren't using a 600 ohm load so it is a little of a misnomer. If you do the math, 0 dBm is the same as 775mVrms sine wave signal source. -50dBm would be 2.45mVrms. FX DEV BOARD IS LIVE!! Check out the Crowdsupply page and get one! See Figure 1!
