Snod35 V1
I am posting this info and the various pictures in hopes of helping other do-it-yourself 35mm adapter builders. The information provided is not intended to be a DIY guide, but simply a sharing of information. Please keep in mind that this design is specific to the performance of the Sanko 1E110 motor. The total cost to build the Snod35 was $280 (including the achromat lens). If you are not sure what a 35mm depth-of-field adapter is, please see wikipedia.org's page on the subject.
The Snod35 is based on the principles of the original Letus35 design. After months of testing and designing, I was so pleased with the images that I was getting with the Snod35 that I decided to begin putting together a Do-it-Yourself DVD/kit. Not long after, I discovered that the vibrating motor that I was using was no longer manufactured. I spent several months testing possible replacement motors, but none came close to performing as well as the original Sanko 1E110 (AKA 1E120) motor. Because the adapter just didn't perform as well without the Sanko motor, I opted not to make the DVD/kits. Unless a forgotten box of the Sanko motors is pulled form a hidden and dusty shelf at some point in the future, the Snod35 V1 will be a one of a kind gem. There are of course ways to alter the design so that the other motors will also perform well. I am currently working on a second version of the Snod35 that will work with other motors.
Building a 35mm adapter can be a tricky and time consuming process. My honest advice would be to consider the amount of time, work, and money you will be putting into the adapter. You may find that you could take that time and effort to work towards buying a professionally made adapter.
To prevent confusion, I will be using the term "focusing element" to refer to the thin plane where the image from the 35mm lens is being projected. Often times the term ground glass is used, but this can be misleading since many adapters use wax or plastic as the focusing element. In the case of the Snod35 V1 the plano (flat) side of a plano-convex lens has been ground and serves as the focusing element. In this way, one piece of glass is used as both the condenser and the focusing element.
