Hello all to the development of the second version of the Beastgrip Remix. Normally I finish a project before posting but for this project I decided to take a different direction. This time around I want to build the next iteration through the notion of crowd sourcing for ideas and suggestions.
Progress of Project can be seen on my tumblr page.
GOALS OF MARK2
~ Rail Frame Design : Main purpose is to allow flexibility in the overall rig. Ideally if you wanted a rig for a tiny phone just buy smaller rods, if you want to use you're 7 inch tablet just buy longer rods. Second is less parts to print, since the rods make up most of the frame. Third, two rails allows to easily attach things to the frame like camera arms or whatever else you can think of can be clamped onto the rails, slide around and screw tight into a position.
~ Different Handles : Going with a rail frame I would like to try to make the handles optional and varied. Initially I will try a more standard beastgrip handle and also one built using bicycle handles.
~ Battery Pack Support : Want a way to attach varied size/shape battery backs. When doing long photoshoots or video recording you need more power then your phone can normally support. So being able to attach a power supply to the rig while plugged into the phone will really make the unit last longer while working. Solar power battery pack for starters, solar takes forever to charge but if you're out for a few hours then its possible to buy a few extra minutes of charge which can always be useful.
~ Shutter Button : This is the big one. First version I used earbuds and Google Cardboard magnet switch. Earbuds volume up button worked the best but its not comfortable. Found tutorials on how to make you're own play/vol buttons for headphone cables, so using that knowledge I want to create a large shutter button that can be attached to the rig for better control of taking pictures, no touching the screen required.
~ Metric : And finally I want to use all metric screws, rods, etc on this build. First time around I used USA screws which is fine but this time around I want the rig to be easily built by anyone in the world, so metric is key, besides I have to model everything in metric anyway for 3d printing.
The frame, Clamp and Lens mount are done with the first draft of the design.
Make some handles.
Create Shutter Button
- This is a big if but maybe use beastgrip's tutorial on how to make a DOF adapter. Need to price out the cost of the parts, it might be cheaper to just order one from beastgrip directly but I won't worry about this till the rig is complete.
Not 100% ok with the design. The lens mount works but I need it to shave off 3-4mm of space. The big issue is the filter ring is 7mm tall and its what I'm using to screw in 37mm lenses. The distance has the corners show a little black which is the walls of the lens. If I put the lense right up to the phone camera it goes away. So I need at most 3mm of space but I have not been able to find a step up/down ring or filter that is thin, doesn't help that amazon does not give you that spec.
So any help or suggestions to improve what I have so far would be greatly appreciated.
After this project is done, or almost done I'm thinking about taking the frame rail design and apply it to a google cardboard design. I created something months ago but stop because I wasn't happy with the design and the parts took forever to print. But the frame design should make things very easy to put together and open up some design ideas. Oculus's consumer model is somewhat a frame design with clothy material over the whole frame, so the same can be possible for google cardboard. I already have the lenses and they work pretty well in the first two iterations of the vr goggles I made. So this frame design would be a perfect method to finish that project.
