Best 25 bux I spent on amazon in a long time. Its a small WIFI microscope that uses your phone.Crazy how a proper microscope nowadays isn't THAT much better than the macro camera on the latest iphones... technology is progressing so quickly. And yeah I don't see an obvious trace or anything coming out of it. Maybe it really does go nowhere and I just got lucky. Do you know if that's a possibility with this type of diode?
