short video of it running a couple years ago when it was partially built. it is on the road and working now. With the near vertical windsield, all I usually need in summer rain is the lowest speed on the intermittent wipe control. Low speed for hard rain. high speed on the motor.....honestly if it was raining that hard I'd probably pull over
it looks a lot simpler than it is. This is after several iterations on the original design. When i started I thought it would be relatively easy, little measuring, little math-ing, cut weld and done. Wrong, I'm not as smart as I thought! The timing and lengths of each component are critical. I'm also not convinced that the OEM vacuum setup gave a full wipe on both sides.
I only have about $50 invested but probably a month of spare time. if I did it again I'd maybe use a single speed rear wiper or just spend the bucks and buy the after market stuff.
