I have just noticed this project on KS:
I think Dobot could do that (even in better with subpixel resolution by moving on X-Y) simply by building an appropriate cardboard enclosure and put inside of it a transparent baque on a smartphone/tablet. I want to try to do that! @Dobot if you finance me a bottle of daylight resin for my tests, I am ok to developp the project and release it as open-source! (hardware design + instructions + multi-plateforme app).
PS: [joke] this is not a reason not to send me my 3D pen, I am still waiting it! :
PPS: I think it could be interesting to create a “developments” section in the forum. I have personally a lot of other projects I plan to test (ex: pick & place + solder SMD for circuit boards … ), and I am pretty sure others have also a lot of imagination!
