Today we pay tribute to a project that I never posted when it worked, but should have, because now it’s too late.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

I downloaded the STLs for this mini (MAC) moving head light<\/a> about 4 years ago and printed them immediately. <\/p>\n\n\n\n

Then for the next 4 years I made several half-hearted attempts to assemble the thing and get it running with an arduino sketch. At some point I had it together with 9g hobby servos, then I decided I wanted metal gear servos so I swapped them out. Getting the tilt servo and LED wired in through the head is a pain, and I think the design puts a lot of stress on the tilt servo that even a MG servo can’t handle indefinitely.<\/p>\n\n\n\n

I used a Lolin32 to drive the servos and LEDs, and at one point I got a YAML config that let me drive the servos and LED via Home Assistant. But I never really used it for anything, every time I got it working with something I’d pack it back up after a couple of days because it wasn’t very fun to control.<\/p>\n\n\n\n

But then I finally got Art-Net working on other ESPs and QLC+ provided the kind of control I wanted. So I got a pretty crappy sketch going that was able to execute Art-Net commands for the LEDs and servos. I watched it draw a figure 8 pattern on my ceiling for about a half hour.<\/p>\n\n\n\n

So yay! I finally found a place for my little MAC light! I’ll just let it sit in the corner and set up some little light show functions for alerts and that will be cool.<\/p>\n\n\n\n

Hey- what’s that’s smell? Did something short out? idk\u2026 oh well, I’ll find it when it catches fire or something doesn’t work any more.<\/p>\n\n\n\n

Hey\u2026 the little MAC light is at a weird angle, thought I had it default to centered\u2026<\/p>\n\n\n\n

Oh, the tilt commands aren’t doing anything, not even a sound from the motor. I wonder if the servo connector came loose- nope it’s on there. I guess I have to pull it apart.<\/p>\n\n\n\n

Hmmm… servo’s a little warm, that’s not great. Do you remember how the servo horn is secured in there? Did I glue it? I don’t think so\u2026 it’s just stuck in there probably, I just need to pry it up a litt\u2026 SNAP\u2026 oh it was screwed in- and the infill density on that part was super low so\u2026 yeah, that’s totally broken now\u2026 and oh, the tilt motor is utterly frozen, can’t even turn it with pliers.<\/p>\n\n\n\n

So that’s how it happened. I could reprint the part but I won’t, I like pan\\tilt lights but this particular design maximizes the MAC light look but probably isn’t the best design for functionality.<\/p>\n\n\n\n

But I spent a lot of time messing with this thing and looks like I’ll never get to post it in action so here’s a rememberance.<\/p>\n","protected":false},"excerpt":{"rendered":"
