There seems to be a problem with the link, all I see is an empty page Likely due to the auto-updates. Need to disable it... | 08:30:26 |

| Artur Scholz | I'm searching for an open source CAN to USB device. This one claims to be open hardware, but I could not find any hardware design of it: https://canable.io/ | 14:12:35 |
| Artur Scholz | Such device would be needed to test LibreCube subsystem boards from a PC (which acts as controller node). I have this one, but it's not open source and expensive: https://www.8devices.com/products/usb2can | 14:14:38 |
| Artur Scholz | The "best" I found is that one, but needs a bit of rework: https://github.com/myaki-moe/usb2can | 14:15:30 |

 cajt | Any SLCAN protocol capable device should work with Linux, can't say much about the built-in ones for Linux ( e.g. zynq, rpi+shield etc...) | 13:22:30 |

| Artur Scholz | jankolmas: Here is the CAD design of the PACE CubeSat structure which I did years ago, it includes the deployment switch. Unfortunately it is only in CATIA (it was years before I was evangelized by open source). I now converted it to STL to be able to open in FreeCAD (you may need to zoom out). | 10:36:27 |

| Artur Scholz | Anyone has comments/feedback to this? https://gitlab.com/librecube/elements/LC2101/-/issues/7 | 21:54:54 |

| cajt | Why not move on to a more symmetric (and metric) design?
Have a look at containers/dispensers with tabs, not only rails. An enclave for legacy "104" boards will be around for some time to come (forever?). But the 100mil stacking connector is electrically ill suited for "higher" powers and higer speed interfaces, so there is a need for innovation here. | 21:56:02 |
| cajt | W.r.t rougness and screw holes, I would interpret the spec differently. See 2.2.9, so 25% holes in the rail should be fine. and 2.2.6 ist only a macroscopic surfaces property, with the intend of guaranteing a proper sliding between the rails of payload and dispenser. | 22:03:12 |

| jankolmas | cajt: good suggestion, we could think of a "v2" evolution of the form factor, which could include deployment tabs and better way of stacking the boards, something like PCIe in a desktop PC | 20:13:30 |
| cajt | Well, I think its a bit more complicated. Regarding PCIe: There is cPCI Serial Space. But the standard's formfactors are cards in a backplane about 100 (Eurocard) and 230mm wide (double euro). | 20:23:55 |
| cajt | And there is about enough space in 2U Cubesat for one Eurocard, right in the middle, diagonally. | 20:26:28 |

| cajt | Also cPCI serial Space (formfactor) is the wong granularity for many subsystem in a Cubesat right now | 20:41:12 |
| cajt | Pushing it all hard engough the whole sat's bus electronics could be on one board, with room to spare | 20:42:11 |

| cajt | I just had a short browse across the ECSS-E-ST-70-32c (Pluto def.) and it kinda looked allmost similar to a hierarchical task network (HTN) model, it only lacked the goal state definition. Is that just coincidence? | 16:57:56 |
