So there ended up being a few issues with v1.0 of the VFD Experimenter. The biggest was that the h-bridge chip I selected to drive the filament with squarewave AC ended up not working as I expected so I ended up hot wiring it for simple dc drive with a current limiting resistor. The second issue was the components for the boost converter are a bit undersized (and thus why the multiplexed tube shown in the video was dimmer than I would have liked). Other than these two pebcaks though the board was pretty useful for experimenting with different random VFDs I pulled from various appliances.
