  • 35376827d1 Moved the lower knuckle out into its own file, and substantially improved it. main Simon Brooke 2025-09-24 12:07:28 +01:00
  • 0a3c553512 Tactical commit before experimental redesign of knuckle. Simon Brooke 2025-09-24 10:25:49 +01:00
  • 72797decb0 Much work on the lower knuckle, and I've learned a lot. However, because I forgot to allow for all the weird skews, this is wrong. It's remediable, but not now! Simon Brooke 2025-09-22 13:49:57 +01:00
  • 775167b4e9 Tactical commit while reworking the lower knuckle. Simon Brooke 2025-09-22 12:01:37 +01:00
  • 025575a488 Work (not yet completed) on the lower knuckles of the four bar linkage. Simon Brooke 2025-09-20 17:49:49 +01:00
  • 1befca0a60 First render with hull! Simon Brooke 2025-09-17 10:46:53 +01:00
  • b95f639c30 Well, the nose is too long, and there are other problems with the hull, but that's a visualisation that works. Simon Brooke 2025-09-16 21:10:10 +01:00
  • 3b90a2e4d5 Added a motor -- actually in the epicyclic file, which isn't right, but... Simon Brooke 2025-09-15 15:57:57 +01:00
  • 87a0c3431e Subframe now switchable between aluminium and carbon versions; TODO carbon variant lacks its wheel leg. Simon Brooke 2025-09-10 18:19:03 +01:00
  • 5231893347 Tightened up components in the subframe; added a sketch showing how the subframe might mount. Simon Brooke 2025-09-07 11:05:25 +01:00
  • ad7c766b2a Changed the illustration in the README to represent progress. Simon Brooke 2025-09-07 08:40:49 +01:00
  • 8a6a6be54f This is tentative: I've moved the subframe back to the origin of the grid in its own model, although I haven't yet lifted it so that its wheel sits on the ground plane. I've rescaled it so that the wheel is the correct size. Simon Brooke 2025-09-07 08:27:31 +01:00
  • 113546782f I've written a hull which in itself isn't dreadful, but which has revealed fragility in the way OpenSCAD handles name collisions. This makes mixing libraries highly problematic. Needs thought. Simon Brooke 2025-09-06 22:18:59 +01:00
  • d2399a464c Added tricycle.scad. Simon Brooke 2025-09-06 09:48:28 +01:00
  • 6940675bbe Added BOSL2 to documented dependencies. Simon Brooke 2025-09-06 08:10:27 +01:00
  • 4473ffa5df Forgot the 'skew' library! Simon Brooke 2025-09-06 08:04:41 +01:00
  • dc364443d7 Merge branch 'main' of ssh://git.journeyman.cc:4022/simon/tricycle-mechanical-design Simon Brooke 2025-09-06 07:54:56 +01:00
  • 012a888b85 Greatly improved pedal; both secondary chain sprockets in place. Simon Brooke 2025-09-06 07:53:11 +01:00
  • 13503768aa Minor fix. Simon Brooke 2025-09-05 21:45:28 +01:00
  • 68b34d2f35 new chainset integrated into the subframe model. Simon Brooke 2025-09-05 21:15:05 +01:00
  • 64f75f21a7 Added the new model files! Simon Brooke 2025-09-05 18:20:59 +01:00
  • 386ecc79fb Added chainset and pedals; but also, now understand where libraries go. Simon Brooke 2025-09-05 18:18:22 +01:00
  • 5d5649ab48 Added a model of an epicyclic. Simon Brooke 2025-09-05 12:31:41 +01:00
  • 4cdce5dc0a A good enough for now, working, parameterised, four bar linkage. Pleased! Simon Brooke 2025-09-04 22:09:22 +01:00
  • 57f1021400 Tidied up acknowledgements in the README. Simon Brooke 2025-09-04 18:14:01 +01:00
  • 3f22298df1 Start made on the four-bar linkage. I need to remember trigonometry. Simon Brooke 2025-09-04 17:27:21 +01:00
  • f863799729 And we have a model subframe which is really promising! OpenSCAD for the win! Simon Brooke 2025-09-04 12:10:31 +01:00
  • bcea01f8b6 Created a git repository to track this. Simon Brooke 2025-09-04 08:35:19 +01:00
  • b12d735c3d Initial commit simon 2025-09-04 07:12:48 +00:00
