I was happy to find in my mailbox yesterday the smaller Neodymium magnets that I had ordered about a week ago. I did not expect them for at least another week. So with a happy grin on my face I got back to work on refining my motorcycle "Fast Glasses". For those of you who just found this post and have not seen the previous news I had posted about this project I have been working on designing and building an easier way to wear glasses when I ride my motorcycle. I cannot wear contacts and do not want to get eye surgery but I still wanted and easier way to wear glasses when I had my helmet on. To put my regular glasses on once my helmet is on is a hassle to say the least and after a couple of hours riding become uncomfortable on top of it all. So this project was born. The idea was to design a new set of glasses mounts that hold the glasses to the helmet instead of my face. Here is the final design.
All of the plastic components for the glasses I designed and made on my 3D printer. The glasses are held into my helmet using Velcro mounting straps and in turn the glasses are held securely into the mounts using very small Neodymium magnets. The glasses are standard prescription glasses that I had set up for my eyes without any arms on them so that they could be mounted to the side frame mounts using small wire clips that I bent into shape by hand. These mounts also hold mating Neodymium magnets that allow me to quickly and easily put on or take off the glasses after I have put on my motorcycle helmet.
I went through several different designs of the "Fast Glasses" to get the bugs worked out of them. On the design previous to the final one I was happy with the mount (shown above on the left) worked but was to thick and caused an effect when driving like having "Blinders" on. Distracting and not good at all. I went back to work and refined the mount to use the smaller (1/8" x 1/8" x 1/2") Neodymium magnets which did the trick. The new mounts (shown above on the right) are only 1/4" thick now and with no "Blinder" effect when wearing them. The new magnets are also plenty strong as each will hold a pound of weight. More than enough to hold my glasses in place while cruising down the road.
Here you can see my happy face as I model the new specs with my helmet on. I worked on a few minor changes to the mounts all day yesterday and finished up with what you see here this morning. The glasses are very comfortable and are solidly mounted inside the helmet now instead of being smashed against my face when I am wearing them with the helmet. It takes me less than a second to put the glasses on or take them off so I've succeeded in accomplishing what I've set out to do. With no "Blinder Effect" now I'm all set to do some comfortable cruising instead of some uncomfortable cursing as I go down the road.
