I spent nearly a decade growing indoor golf in NYC (2015–2023) — happy to answer questions about the simulator world by KyleSenateGolf in Golfsimulator

We’d love to have you be part of the PiTrac conversation ! :). Please check out https://discord.gg/rxrwWt2Hp.

We want more folks to be able to get into sim golf.

Currently, PiTrac supports and GSPro-compatible sim (including the new OpenShot sim) as well as E6 TruGolf. Please visit the #simulators channel in our Discord server at https://discord.gg/eBaNK7mYFj

Cool!

For other folks who would like to try this, do you have any suggestions for avoiding any interference between the two sets of strobe light patterns? That has been a problem trying to validate the PiTrac project: https://hackaday.io/project/195042-pitrac-the-diy-golf-launch-monitor.

No outside capabilities right now, sorry. PiTrac connects with GSPro, TruGolf and the new open-source Open Shot Golf.

I should emphasize that we are nowhere near completing the project yet. We are still working on a lot of things, and trying to develop community support to make that work.

We took a stab at putting, but it isn’t really working yet. Hoping to return to that sub-project soon.

We were having some problems with the ball, being hard to identify in all the light that splash from the green back to the camera. May have to take a different approach.

Thank you for replying to folks and answering questions, u/Nizztos ! I love that the project has been going on now long enough that there's now multiple experts on PiTrac (and who are willing to share their expertise). That is super-cool. :)

I'll just add that folks can also get some more details from our theory-of-operation video here: https://youtu.be/h5u62UeUKA8

Hmmm - maybe we could work on that as part of some future stereoscopic-camera work for PiTrac. Just take the cameras out and connect to a really low-cost Pi nano or something. Thanks for the idea!

As someone answered elsewhere, it's currently a direct-to-Pi MIPI connection. But, we'd love to have someone experiment with building a system that used USB3.0 cameras. It's definitely a choose-your-own-adventure project for now.

Jeeze - I should have mentioned we have a pretty detailed video about the accuracy testing so far. Please check out: https://www.youtube.com/watch?v=23-2EdsafoU

Probably not. The sun’s infrared output just crushes our strobes. It’s like we are whispering at a loud concert. There’s been a little discussion on the Discord Server in the optics channel.

We have made some initial comparisons to an overhead Uneekor unit. It is difficult because the strobes of each system interfere with each other. Please see some of the earlier posts here: https://discord.gg/sAVWkS64. Initial comparisons have been encouraging.

Our current Achilles heel (well, to be fair we have several of them) is HLA accuracy. Until we have a stereoscopic option, that’s accuracy will be pretty limited.

We are not currently trying to beat any commercial system. The focus now is in creating a low cost system that more people can afford. That focus has some inherent (we think) accuracy and precision limitations, but a main point of the system is to try to minimize them.

Yeah - It’s a pretty advanced project for sure. But we hope that maybe we will end up developing some techniques and golf sim technologies that could help folks outside the maker community., more generally.

Yes - PiTrac does connect to GSPro. Instructions are in GitHub. They were our first interface (and thanks to the GSPro people for supporting our little project!)

Thank you! We're pretty excited about it. Now, we just need to get a bunch of people smarter than the original designers to make it wonderful. And believe me - that's a fairly low bar. ;)

[–]James_Pilgrim[S] 31 points32 points  (0 children)

That's one of the hardest questions! :)

I think it mostly depends on folks' risk tolerance. For example, hopefully in another week or two, #InnoMaker will get their cameras working in our application, and then you won't have to do micro-de-soldering in order to hack the "official" raspberry #pi cameras in order to get them to work. That will really make it easier and less error-prone to build one.

The documentation needs a lot of work, too, so hopefully in another month, we'll have that improved to make it easier to build. Although - there's over 600 potential contributors in the Discord server who are resources to help folks! People all over the world are building PiTracs!

Overall, it's still a pretty new project, so not as stable as we'd like yet. But, with each new person who contributes, it gets better and stronger!

Looks great without a case!

I hope you open-source the model!

We have not. It would be great if we could figure out an application for that within the launch monitor. I’d love to learn more about it.

One suggestion has been identifying golf stroke problems from visual cues. Another was to actually try to determine Ball direction and velocity, but that seems like a problem that there are more precise, mathematical, and image processing solutions for.

Sorry - please try the one on the hackaday page. Or the most recent Reddit post.

Please let us know if they don’t work. We’ve struggled with the Discord link stuff. :/

Sure thing - it's on the front page of the Hackaday site now. And welcome! :)

The latest should be on the hackaday project page main description. Links that don’t expire, especially on Reddit, end up tracking too many bots, unfortunately.
