Jog Wheel from VCR Head

Jog Wheel from VCR Head

Rohit is an engineer who found himself turning through pages and pages of PDFs. The solution he created, from his site:

Now the simple solution would be to buy myself a jog wheel / spinner. Give the jog wheel a slight twist and its momentum would keep it gliding over pages and pages of the boring PDF. But I’m an engineer. So I decided to build myself one (obviously the phrase “Why buy a cow when milk is so cheap” does not apply to engineers).

Rohit reverse-engineered the pinout for the chip on a USB mouse to find the right pins to attach the VCR head to. Once finished, his device works like a charm, and looks pretty sharp too.

    How did you get the wheel to sit at a right relative angle? Most VCR heads are at like 30 or more drgees tip.

      The bracket holding the head in the VCR is the only thing making the head tilted. The head itself is just two “wheels” with a shaft through the middle (bearings and what-not of course too).

        ^^Exactly. I didn’t really have to do anything to adjust the angle.

    For the first 12 hours I had no idea what you were attempting to do…. so you turned an old VCR part into a mouse?

    1. Rohit de Sa says:

      Hehe, yeah. Not a complete mouse, just the scroll wheel part of it.
