Mike's Rodless Pendulum Clock Build
I thought I'd show you guys some of the work I'm doing in making a unique pendulum clock. There's several videos on my youtube channel. Here's some links:

And one of it under electromagnet power:

It will eventually be all mechanical, but I wanted to get it oscillating and it ran quite well. The idea is to approach isochronism, where the period does not change with amplitude, making the need for perfect impulsing less strict. The roller approach is a high friction one, but the bob mass is following a near perfect cycloid path, which is part of the battle. Next up is to have the bob on a bearing so it does not rob energy from the system by rotating back and forth.
