Kerbal Instrument Panel: In-Desk Apollo Themed Hardware Controller

Construction of the custom desk is complete! It just needs electrical work! Electrical work is done! Pictured above, the current (as of Dec 2020) mockup of my end goals for this project. I've been working on this project on and off since around June of 2015... I initially first appeared on Page 6 of the Simpit Repository where I showed off some really nice hardware I'd collected for the project. The goal is to create a controller using real instruments to provide readouts of orbita

Here it is! The 115vac 400Hz Amplifier. Takes my 10v p-p reference sine wave from my California Instruments 850T Precision Sine Oscillator, and boosts it up to enough voltage and current to drive the Navball! This schematic doesn't show the rectifier or the bulk capacitors that create the +/- High voltage rails, but those portions of the schematic are textbook. Also since added is a resistor and coupling capacitor to a shutdown pin on the primary op-amp. I caught that one. Th
