Muller Motor project updates
Here are a few photos of the assembly so far along with scans of the schematic and board layout for the driver circuit. Click each image for a closeup look. Please be mindful that this is a work in progress. As such, what you see here may not always be up-to-the-minute. Keeping this web site up to date takes time. I will get to it when I can. Here also is a direct link to my YouTube Muller Motor Playlist. It's all there.
