Post inventions/ideas you’ve had that you don’t have the resources and/or knowledge to patent and produce.
Here’s one I came up with recently that I really wish existed so I could use it:
It’s a DSLR camera docking station for your smartphone. Basically you take a typical DSLR camera and remove almost all the buttons, screen and processing hardware. Then, in their place, you put a dock for a smartphone. You use the camera’s lens and image sensing equipment to take the photos and then use the smartphone for processing and ui. The smartphone end of the operation is handled by a preferably open source app that allows you to access all the DSLR’s settings like on any current DSLR camera.
That’s the basic idea, but there’s a few additions to make it better. For example, the docking station would just be a large rectangular inset big enough to fit most phones. You’d then buy a 20-30 dollar case designed for your specific phone that would fit seamlessly into the rectangular inset on the DSLR. Also the DSLR dock could come with a typical DSLR camera’s battery to give it extra life and help power all the camera stuff. You could give it bluetooth capability so that you could take group photos with the camera end on a tripod and the smartphone end in your hand where you can access settings, preview the shot, and take the shot (not sure how this would effect the image processing, may not be possible). If the earlier part is practical, you could make the tripod screwhole on the bottom of the camera attached to some servos so you could use your smartphone to pan back and forth to better position the shot.
Basically you’d take the best of the DSLR cameras and combine it with the best of smartphones.
