I was recently thinking about a VSS solution for a marine application. I'm only in the idea phase for now. One idea that I have is to use the TPS output (0 ~ 5 VDC) as an input for a DC motor controller. I'm thinking the computer TPS circuit would not provide enough current for even the smallest of DC motors? The DC motor controller will speed up / slow down a small DC motor mechanically connected to spin a VSS. Hobby RC type motors and motor controller (with a dead band adjustment) are possible sources for my parts.
