Question re build and radar

[mausland]

Hi all,

I'm considering building this unit now. I did some AI research about this build v commercial builds and this looks like the way to go for DIY folks. Research is saying this is comparable to $1500 units but with no subscription issues.

One of the things that was mentioned was the alignment of the radar units. The relevant part:

"The Problem of Radar Alignment
Alignment is the single most important factor in launch monitor accuracy, particularly for radar-based systems. In professional units like the Trackman 4, the internal camera is used to help the user align the unit exactly to the target. In a DIY build, the user must manually align the OPS243-A and K-LD7 modules using a laser level or a mechanical jig. A misalignment of just 2 degrees can result in a significant error in horizontal launch direction (side angle), which in turn compromises the calculation of side spin and total distance."

Has anyone built this unit and tackled this? If so, how was it handled? Any other thoughts, comments?

Thanks,

Mike

@mausland - i've had a back and forth about this a few weeks ago with @jewbetcha and I believe this can be solved by re-introducing the camera back into the build, mounting it above the KLD7 radars and using the ball position in relation to the camera to determine the horizontal and vertical offsets. It's on my todos to explore this more in the coming weeks.

Sorry for the late reply! I think this is a good idea that we might seriously consider moving forward. Toughest thing will be to get the positioning/alignment right, but the good news is that we will be able to use a super cheap camera module for it
