We have an issue here on a Limelight 3 that we purchased at the beginning of this season through Andymark.
We noticed the blurriness at out district championship in April but it wasn’t really an issue for us because we never were able to get the vision support on the robot up to speed.
Then we lost our teacher in the school so we haven’t been able to verify the issue until recently.
When we purchased everything was fine - but now everything is extremely blurry. It’s like the auto focusing is not working or something.
Have you got any documents we can use to troubleshoot and remedy this?
I have some screenshots that the students were able to take in some testing - you can access with the links below.
I tried messaging Brandon a week ago, no response. And I hit the contact us page on the limelightvision web page on the weekend and haven’t received a response.
Thanks for any support or ideas you can provide

We had this happen as well - In our case the lens was knocked out of alignment with the camera sensor.
This is the hit that did it to us - it doesn’t look like much but cameras aren’t really built to withstand impacts. It’s happened multiple times since then, mostly because our limelight is in a vulnerable spot on the robot. Lesson learned, I guess.
I’ve been told that we were able to realign it manually, but I doubt the camera has the same distortion after the repair as it did beforehand. No data to support this claim either way though.
You might be able to realign it manually? Hopefully Brandon reaches out to provide some guidance here.
addendum: We reached out after MSC and Brandon replaced this limelight with a new one. We have not reached out for support w/ regards to the offseason failures.
We’ve had this happen from impacts where the lense jumps threads on the sensor housing, someone with the right skill set can disassemble and reassemble the limelight with the right focal length (or eye ball it with the video pulled up on a laptop) and re-glue to retain the location.
I ended up taking it apart and adjusting the lens position relative to the sensor which wasn’t too hard. Things are improved but I’m not sure I have it all the way because the image looks very noisy.
Is anyone able to post some screenshots so I can compare the image quality?
