| xfxf | mithro: a friend just posted this: https://m.facebook.com/story.php?story_fbid=10153844936806722&id=520981721 | 06:11 |
| tpb | Title: Comments (at m.facebook.com) | 06:11 |
| mithro | xfxf: PTZ tracking stuff isn't new at all, plenty of closed source implementations | 06:13 |
| xfxf | The use of the vive I mean specifically | 06:16 |
| xfxf | I'm aware ptz isn't nre | 06:16 |
| xfxf | doubt it will work for our use case of larger rooms but still super interesting | 06:17 |
| *** Bertl_zZ is now known as Bertl | 07:39 | |
| xfxf | mithro: also https://multicamzilla.com/ | 08:06 |
| xfxf | but closed too | 08:06 |
| xfxf | and no tracking | 08:06 |
| xfxf | there's zero affordable USB/serial-controllable PTZ tripod heads I can find | 08:07 |
| xfxf | or the ones I can find look like they're straight out of the 90's | 08:07 |
| xfxf | how much you reckon we could manufacture one for? ;) | 08:07 |
| mithro | xfxf: I pointed you to the jaycar one right? | 08:08 |
| mithro | that was only PT though, no Z | 08:08 |
| xfxf | i think so, was that the one that looked uber dodgy? :P | 08:08 |
| xfxf | and doesn't need Z, that's a camera operation | 08:08 |
| xfxf | which is a good point, i might need to implement LANC or something | 08:09 |
| mithro | it was the one designed for like a go-pro type thing | 08:09 |
| xfxf | i think my cameras support some common protocol | 08:09 |
| mithro | xfxf: https://www.jaycar.com.au/pan-and-tilt-action-camera-bracket-mount-for-9g-servos/p/XC4618 | 08:09 |
| tpb | Title: Pan and Tilt Action Camera Bracket Mount for 9G Servos | Jaycar Electronics (at www.jaycar.com.au) | 08:09 |
| mithro | ~25 AUD (the bracket + 2 x 9G servos) | 08:10 |
| xfxf | i'm not sure that's quite tthe same thing | 08:11 |
| xfxf | description suggests adding an accelerometter | 08:11 |
| xfxf | this would be much more work to implement/build | 08:11 |
| xfxf | i'm happy to spend $400 or whatever on a solution that's already assembled that i just need to write an interface to | 08:12 |
| _florent_ | mithro: for a camera, a pan and tilt with brushless motors is probably a lot better than servos... | 08:48 |
| _florent_ | mithro: something like this: http://www.hobbyking.com/hobbyking/store/__974__973__FPV_Aerial_Video_Telemetry-Brushless_Gimbals.html | 08:49 |
| tpb | Title: Brushless Gimbals > Camera Gimbals > FPV, Aerial Video & Telemetry (at www.hobbyking.com) | 08:49 |
| _florent_ | mithro: servos are noisy and not very accurate... | 08:49 |
| mithro | Yes | 08:49 |
| mithro | xfxf: As _florent_ pointed out, you might have success looking at quad copter and drone stuff | 08:50 |
| _florent_ | mithro: it's mostly used for stabilization but I think you can also use it for tracking | 08:51 |
| mithro | _florent_: Yeah, they are kind of the opposite of each other right? one the target is moving, you are staying still - other one you are moving and the target is staying still :) | 08:52 |
| _florent_ | mithro: yes that's the opposite, but the mechanical can probably be reused | 08:53 |
| _florent_ | mithro: the only thing is that you don't have lots of torque with brushless motors | 08:53 |
| mithro | They are also probably weight sensitive | 08:54 |
| _florent_ | if the system is well balanced it should not be a problem | 08:55 |
| mithro | _florent_: well, even if 10kg is well balanced, that is a lot to lift :) | 08:57 |
| _florent_ | yes of course but I'm also not sure you can put a 10kg camera on the pan and tilt from jaycar.com :) | 09:00 |
| mithro | _florent_: also true :) | 09:08 |

| mithro | _florent_: Did you want to organise an evening this or next week to hack on opsis-soc stuff together? | 10:10 |
| _florent_ | mithro: yes, we can plan that next week | 12:22 |
