The Hasselquad

Analog Aerial Photography Platform

Similar projects worth following
Medium format film photography from a quadcopter. Including the shutter remote trigger and the FPV viewfinder module using mostly off-the-shelf components.

What's already completed:

  • Quadcopter, these are a commodity and will not be going into too much detail.
  • Camera mount, currently fixed until I decide I have to have a gimbal for straight horizons.
  • Remote shutter, the camera I'm using has an electronically controlled shutter. This was easy to trigger from the radio receiver.
  • FPV viewfinder

In progress:

  • Camera gimbal mount

  • To Do

    Test flight with real camera attached.

  • ​FPV Viewfinder Version 2

    Richard Hogben07/14/2017 at 16:57 0 comments

    The 3d print is getting there. One thing I forgot to play around with was removing the ground glass screen altogether. Then the design could work similar to the prism viewfinders.

  • Viewfinder Video Transmission

    The focusing lens mount is visible because the CCD camera lens is just a bit too wide. At least the image looks generally in focus and I can make out the crosshairs.

  • FPV Viewfinder Version 1

    The wall thickness on the 3d print ended up being ok. It's still thin and I'll increase it for the next print but another problem arose as I set everything up.

    In my attempt to decrease the overall height of the viewfinder I forgot that the ground glass on the camera has a minimum distance to avoid vignetting. It's called a 'waist level viewfinder' for a reason :) and I had the CCD lens way too close.

    The result was terrible vignetting on the receiving display. I've increased the height and moved the CCD lens up about 4 cm. The CCD mount, biconvex lens fit, and other dimensions are very good.

  • Minimum Wall Thickness Fail

    The viewfinder walls are too thin unless the part is printed on something like a formlabs machine. I've already adjusted the model and will see how the existing part turns out but I'm assuming it won't be strong enough. All the walls are now at least 2mm thick. I also took the time to add some fillets on any edges that might be under stress.

  • Radio Controlled Cable Release

    Very easy, just short pins one and three. Wire the DIN to a relay (I purchased mine but these are easy to DIY). Connect the relay to the radio receiver and setup the receiver channel to respond to a switch from the radio controller.

  • FPV Viewfinder for Hasselblad System

    Richard Hogben06/27/2017 at 02:08 0 comments

    The viewfinder holds a focusing lens, small camera, transmitter, and battery. My first prototype is modeled after the waist level viewfinder but with the above modifications.
