Motorized Zoom Lens #2 - Motors working, IR filter installed

Last video I showed the lens working on a PCB from an old webcam, this time I also have the motors working, and an IR filter installed. Next video will be about auto-focus.

Motors: The motors are tiny bi-polar stepper motors you can also find on eBay/Ali-express (for the pin-out). It turns out they are small enough to direct drive from an Arduino.

Last video I experimented with a google wavenet (robot) voice-over. This time I am doing voice while filming. Still in search for a format that suits me well, and does not take three weeks to edit :)
