I was originally going to make this up into a clear and detailed write-up but decided that since everyone doesn’t have the same phone, want to buy the parts I used or assume they could cut up and resolder the light, I opted to make it an inspirational post (or maybe I just got lazy, but my other reason sounds better). So I bring you my phone holder thing…
I wanted to have a way to take pictures things that I need to engrave so I can layout the artwork properly. I hoped that the EM2’s camera would remove this step but so far I haven’t had a ton of luck with it being accurate enough. I used the arm from a USB microscope stand so I could move the phone smoothly and lock it into position. To get clear shadow free pictures I took at selfie ring light and removed most of the plastic but the light ring itself. I soldered longer wires so the battery pack could sit on the table and not be in the way. The 1cm engraved grid pattern is much more precise then taking pictures or scans with grid paper since the lines are a beam’s width instead of a random fuzzy ink line. With the grid I noticed some fisheye from the S9's camera, its slight but never noticed it before when using graph paper.
The phone holder pops out of the microscope arm and the boom comes off the baseplate so everything can be broken down and transported/stored easier. Overall I’m pretty happy with it, a few things could have gone better but since I only needed one it isn’t worth going back and doing over again. I bought a Bluetooth shutter trigger so I didn’t introduce any shaking when taping the screen, but it’s more stable than I expected and haven’t needed to use it.
