These photos depict the final design for the digital tattoo machine. The machine took one a half months from start to finish and I have learned a lot from building it. There are still a few areas which aren’t perfect, but it functions well enough to do outlines of any design that you give it. The only area I see that really needs to be improved is filling in a shape as that has caused some difficulties.
The tattoo machine can be calibrated to any size arm and it only takes 25 minutes to get a high resolution scan. From there, small tattoos take anywhere between 1 and 3 minutes whereas longer ones that need to be filled in can take up to half an hour.
