Thus it can be applied to all contents of this repository. Having only one license makes the license structure for this project way easier. Since the OHL is written with hardware in mind it likely fits better to this open hardware project. 2024-01-27T19:16:49Z xengineering me@xengineering.eu 2024-01-27T19:08:40Z urn:sha1:6b6ed366ad186dce77467fc6e1ea97fa25ac393e 2024-01-26T18:00:06Z xengineering me@xengineering.eu 2024-01-26T18:00:06Z urn:sha1:13ffb7887a6d0eb488eb957b133194fec89198de The y dimension of the shell connectors was assumed to be bolt_l. But this ignores that their thickness is bolt_l-t because the bolt has to go through the shell with thickness t before entering the shell connector. 2024-01-10T20:07:42Z xengineering me@xengineering.eu 2024-01-10T18:46:10Z urn:sha1:cad2b003b8c936237a909d4076beb0bfd6607b00 The positions of the connectors had to be adapted to the new PCB case dimensions. Furthermore the micro USB port which is built in to supply the device with power is now the only visible micro USB port from the outside. The other one is unused and could lead to confusion. User might plug in the power cable into the wrong port. Hiding this misleading USB port is an elegant way to avoid this problem. Developers can still open the device to make use of that port if required. 2024-01-09T19:14:31Z xengineering me@xengineering.eu 2024-01-09T19:14:31Z urn:sha1:ca969ac44ea1c2194193eb444c4e6e8ca222c8bf The front panel has to be very close and thin so that USB and HDMI cables can still be connected when only the ports are cut out of the panel. 2024-01-09T18:59:04Z xengineering me@xengineering.eu 2024-01-09T18:59:04Z urn:sha1:c9fb2c1531fd1430fb2034fa3edbb41f7b69b385 Since a proper norm-based distance bolt was not found printing spacers is the easiest way to make the case producable independent of part availability. 2024-01-09T18:44:42Z xengineering me@xengineering.eu 2024-01-09T18:42:22Z urn:sha1:ca53dd20c9f45809888b3a0511c223847e97988a This makes sure that the bolts inside the connectors align with them. Thus the bolts do not stick inside the case which might lead to PCB collisions. 2024-01-09T18:26:25Z xengineering me@xengineering.eu 2024-01-07T17:19:40Z urn:sha1:78447efe6110cd4cfd6a48fd05b1cd8139f02894 The height should take into account that the shell is two instead of one times the thickness high. This is relevant for the vertical spacing. 2024-01-03T14:49:07Z xengineering me@xengineering.eu 2024-01-03T14:46:15Z urn:sha1:791f48f6a7e8ea342ca649bfc74d3d82379ca07e The CAD model of the full assembly might be useful to be included in other projects or CAD files. 2024-01-03T14:49:07Z xengineering me@xengineering.eu 2024-01-03T14:47:16Z urn:sha1:4815a8bc45db240fcb6fc518235112d328abb9d1 Most users will not own the default printer and thus cannot work with the built gcode files with the default slicer configuration. It might be easier for those users to manually slice the STL instead of modifying the soundbox source code. 2024-01-03T11:03:43Z xengineering me@xengineering.eu 2024-01-02T21:51:35Z urn:sha1:a72e170df8344ac66c799156a744953cb762e08b This target removes the build directory and is thus repository-global. 2024-01-03T10:25:03Z xengineering me@xengineering.eu 2024-01-03T10:18:28Z urn:sha1:9d87552f99b70ea9d8a8037b67e9be240f5957ce The front panel needs holes for the HDMI, micro USB and cinch connectors of the Raspberry Pi Zero W. 2024-01-02T19:43:21Z xengineering me@xengineering.eu 2024-01-02T19:43:21Z urn:sha1:7763f3f158c56cc3a8478d403156fe507646c181 2024-01-02T19:29:40Z xengineering me@xengineering.eu 2024-01-02T16:09:17Z urn:sha1:5371d56bd722c320c6a76753a6e68d9407cadbe3 After switching the panel to PCB-based dimensions the shell follows with this commit. 2024-01-02T19:26:15Z xengineering me@xengineering.eu 2024-01-01T22:41:18Z urn:sha1:285e100abf2ec0736cded36aba938098b1b7bb60 The whole case should move from case- to PCB-based parameters. 2024-01-02T14:16:53Z xengineering me@xengineering.eu 2024-01-01T22:22:23Z urn:sha1:84796898e32af3374f5e8ce22e686e04f6f6d11e The long term goal is to switch from case-oriented parameters to PCB-oriented parameters to simplify re-using the pcb_case library. 2024-01-02T14:16:53Z xengineering me@xengineering.eu 2024-01-01T21:55:21Z urn:sha1:e9ec4e46cbf3b8a9f9fdefb6fa94dce23bc116f2 This makes the file structure simpler and makes it easy to produce the whole case in one run. 2024-01-02T14:16:53Z xengineering me@xengineering.eu 2024-01-01T19:42:20Z urn:sha1:a3ef23906f2b71486d818fd06ca6ffb0c82e3b1c This value used to consider only the required space for the Raspberry Pi Zero W board, not for the required HifiBerry board. 2024-01-02T14:16:53Z xengineering me@xengineering.eu 2024-01-01T17:10:07Z urn:sha1:35ec58bf32d9a8706e9c0e7c42d40a59bd793319 2024-01-02T14:16:53Z xengineering me@xengineering.eu 2024-01-01T16:28:46Z urn:sha1:187cf96353817701bb49d51117f2dd4f5099e597 This will help to identify calculation issues by human visual inspection.
