This is an idea of making a simple HUD display using a viewfinder of a VHS camcorder. First thing i did is bought a VHS camcorder online for couple of quid's & tear it down.
Actual camcorder used in project.

Unable to find data sheet or Pin-out i started to find its pins by selecting the +VCC volts at 5VDC(as camcorder's battery was 7.2 Volts). Finally after finding out the pins, i tested its display by connecting it to my laptops VGA port by using VGA to Video out cable.
Viewfinder's video testing using VGA-Video out cable(left) & 5 VDC are applied but Laptops USB port(right).
Now for mounting the viewfinder near my eye i used Bicycle helmet, and also enclosed my basic electronics like Battery for power, switch for on/off, Video-in port and charging jack. in a hobby box and mounted on the helmet.

My project didn't finish here, it is still to come more, with lots of other features like digital video feed and live cam feed with enhanced details like image processing so keep following. Thanks.
