Celebrating my first sharp star photo with a homemade tracker

I've been trying to get into astrophotography for months, but star trails kept ruining my shots. Last weekend, I decided to build a barn door tracker from some scrap wood and an old camera tripod. It took me two evenings to put it all together, mostly after the kids went to bed. I used a slow motor from a broken DVD player to drive the hinge. Last night was clear, so I set it up in the backyard. I aimed at Orion and took a five-minute exposure. The stars came out sharp, no trails at all. I'm so pumped that this janky setup actually did the job.
