Hey Jack (@jkallmeyer), there is nothing wrong about being a perfectionist (I got the same problem … lol). It is just the circumstance that this device costs just 5-10$. I have seen multi 100$ setups with results not better than this. The market for such devices is rapidly growing and that will give some of our folks new opportunities, especially when you work in places such as a low income school system (like Tynessa does in Texas). Such devices can help to engage kids for science and increase their education.
Btw: My wife is actually an engineer in optical physics working for a big German manufacturer of high precise optics. She thinks (like all the other engineers in the business) that the potential of modern cell phone cameras is enormous, and by the time the attachable devices will increase their quality we might expect some surprises 😉
cheers
