Macrofab Engineering Podcast

**Podcast Notes*** Parker and Stephen continue work on the [Super Simple Power Supply](https://github.com/MacroFab/SSPS). There is a full on simulation of the analog section on MultiSim.* Stephen found a better way to control the analog end with two separate 16bit DACs. One controls the negative end and the other one controls the positive end of the ompamp. 16 x 2 Blast Bit Processing! * Parker is working on a ESP8266 development board for the Parallax Propeller called the [Bit Flicker](https://github.com/LonghornEngineer/Propeller_Development_Bit_Flicker). Will use the [blynk.cc]( http://www.blynk.cc/). This will enable the SSPS to be IoT enabled!* SAIM Servos arrived. Chassis should be finished by Monday. They past the built in servo "test" routine. See Figure 1.* Transistor Wars: The Vacuum Tube Strikes Back. [Vacuum channel transistor](http://spectrum.ieee.org/semiconductors/devices/introducing-the-vacuum-transistor-a-device-made-of-nothing) that switches as fast as 460GHz. No substrate for the gate and h
