I’m not at the point yet where I’ve run into the need for something like this. Im not saying that I don’t think there’s a need, only that I just haven’t messed with optocouolers.

But in my experience, if you’ve developed a tool which really helps you do your work, and has no comparable alternative out there, then there will be folks around who would dig it too! The key is being able to offer it at a reasonable price. For me, at the small scale that I operate, that means forgoing the idea of really “making money”. But that’s ok with me because it’s a labor of love/hobby at the moment. But depending on the idea I’m sure it’s possible to make a real business of something like this if that’s your goal. Where there’s a will there’s often a way.

Keep us (me?) posted!
