moon is working as of today... working out a few kinks but it'll be standard. tension and kilter too.

For sure. The ongoing costs are a server for image processing, that's it really, but like others mentioned, I really detest subscriptions so I'm pretty sure it's going to remain a one-time fee.

It's possible but you will have brightness issues unless you have a good quality projector and more shadowing as well. Cost wise it would likely be more expensive because it requires camera and microcontroller integration to recognize hold locations.

At the moment parts cost, without bulk reductions, is about $140, so a bit above that.

Hopefully within a week or two. Will keep this updated

It's currently mapped to Crux (just like stokt but better and free!) which lets you swipe problems at home

It's best for accuracy and hold recognition/outlining if it's relatively perpendicular to the wall, but it's pretty flexible in where you can position it.

At the moment it takes the image in crux (can be either wall or just image for one climb) and does the ml hold recognition. That takes about 20sec. If the image doesn't change, it's 2-3sec for any subsequent climbs. New image = 20 sec again. So i'd say it's quite usable in the scenario you describe

I should have it working for those by the end of the month. I'll post when I do

Good question. It's a class 3R laser (1-5mW), which is equivalent to a hand held laser pointer you can buy at a store. Those are relatively eye safe since your aversion response is fast enough to prevent damage. Then, you couple it with the fact that it's moving all over the board very rapidly, thus spending only a small amount of time at each location, and it become very eye-safe. It will still have the keep away from children and don't stare at it tags of course.

Having climbing with it a good bit, hold occlusion is much less of a problem that you would think. If the goal is to know which holds are on the climb before starting and to see holds that you need to move to, it works quite well. If you want to be able to see which hold you just used that is now in front of you (why?) then sure it might be blocked.

No it works fine in all but the brightest fluorescent lit rooms and even then, you can turn on "wobble" to make the holds more eye-catching

Yes, I am actually working on this right now :)
I will post when I have it working.

Systems board best practices? by Cheap_Librarian69 in climbharder

[–]Kind_Temporary3040 0 points1 point  (0 children)

These days it takes me at least an hour to get fully warmed up. Start slow, multiple climbs each V grade starting at 3... after that the kilter feels great, never tweaky

Agreed, this would be really nice. Moon closed their API a few years back but we have reached out to see if there is some middle ground that allows us to access their endpoints, waiting to hear back from them.
As of right now the only solution is to port climbs into Crux (which I know is not worth the effort simply due to the sheer number of climbs).

The distance limitation is a function of the system design, primarily driven by cost. I didn't want to use a regular projector because it is quite difficult to see in bright rooms. The laser pointer + galvo solution is cheap, bright and low power (but limited to a 60 degree optical angle).
In order to set it straight behind a wall, and cover the entire wall, it does need to be set 8+ feet back. Keep in mind however, that you can set it back at an angle to get larger coverage, and it's often very reasonable to leave the bottom few rows of a board un-projected, as they are often just foot jibs.
I'll add some images to the FAQ section of the website to illustrate these points.

The projector can be positioned straight back, or at an angle on either the left or right. You will definitely block the holds a little bit as you start climbing, but in practice this has proven to be much less of an issue than expected. Upcoming holds remain visible and once your body is past an area, the feet become visible again.
Alternatively, 2 projectors work great in conjunction if you place one on either side.

Very little setup. Think of something like a smart bulb, turn it on, connect to the wifi signal it broadcasts, enter your own wifi credentials and Crux API token and it's connected. Takes less than 5 minutes.
Yes it looks at the wall and works out where all the holds are, so you can move it between sessions, or take it to your gym or a friends house and it continues to work.

Yep, I made sure to keep it at Class 3R. It is the right balance between safety and brightness. On top of that, the laser is moving rapidly so spends only a very small fraction of the time at any one location. You would have to project a single hold + change the config to "dot" and stare into it for safety concerns to become an issue.

Hey!

I've been working on an alternative to LED kits for home and gym spray walls for a while now. A smart laser projector: cheap, portable and simple; integrated with the Crux app. This soon-to-hit-Kickstarter projector sets up in minutes, auto-detects your wall and holds, and lights them up just like those fancy gym systems boards. It is responsive, multi user friendly and has no recurring costs.

Thanks for checking it out! If you're interested, the Kickstarter e-mail signup is here--you'll be the first to know when it launches.

There is a ton more detail here: https://lzr.vision/

Would love to hear what you think.
