MEP EP#214: It is Probably SafeParker Just got back from vacation Have not worked on any projects since last episode Watched lots of old er James Bond movies Should we do a Spy gadget episode if we can get the right guest? Stephen Simulation of the Week: Behringer Model D Oscillator Core Lots of cool stuff going on Exponential converter Constant current capacitor Discrete opamp with discrete comparator CNC Update Base built and topped with a torsion box ¾” MDF construction Gantry is on but needs some love New Spindle has 80mm mount This does not fit on my current z axis Make a mounting bracket with leftover aluminum from previous project New transformer for rackmount guitar preamp Old configuration was to do a 115:12.6 transformer then feed that into a 12:230 to get back up to high voltage Simple math says 230/12 = 19.16 so, 12.6*19.16 = 241.41VRMS = 341.36VDC In reality I am getting 250V…. Hopefully with the new transformer ratio I will get closer to 300V whi
