Used Walgreens Photo a few times when I needed quick prints, and honestly, it’s been a mixed bag. Some prints came out really nice, especially on glossy paper, but one time, the colors were way off compared to what I saw on my screen. I brought it up at the store, and they reprinted them for free, so that was a win. Had a question about a missing order once, so I called walgreens photo phone number to check on it. Took a little waiting, but they did track it down and got it sorted.

I see it’s been a while since you’ve posted, but I just wanted to ask—have you tried using a USB microscope to inspect your solder joints more closely? It really helped me catch some tiny issues I missed with the naked eye. Also, curious if you ever sorted out the analog oddness mentioned—could grounding or power supply noise have been part of the issue?
