Whilst I've found many narrow gauge builds, yours is the only one I've seen that's powered and with any hint at the mechanism beneath.<br /><br />I am currently designing, entirely in Lego Digital Designer, a Lego orrery (mechanical solar system model) for a public stargazing charity I volunteer at. An EV3 brick powers an axle which drives a very complex gearbox, rotating the Sun every 33 days, an Earth on an arm around the Sun every 365 days (and on it's tilted axis every 24 hours) with a Moon orbiting every 28 days.<br /><br />I've hacked the EV3 brick to run Python code on Linux and have built a graphic interface (illustrating radial velocity motion, transiting light curves, moon phases, seasons and calendar).<br /><br />I'd love to add a second planet in orbit (Mars) but this would be unwieldy on an arm or using the current gearbox. A circle of black narrow gauge track however would be perfect! I'd plan to make two train carriages: one carrying a second EV3 brick on its side as a slave to the first over Bluetooth; with the second carriage having a mounted Mindstorms motor to drive the 'train' and also rotate an attached Mars every 25hrs. Do you think this would be possible? I note your curved tracks are softened with intermediary straight tracks, but this would have to be circular. Of course an old Monorail or 6-stud railway would be simpler but would make the model unwieldy for taking in to schools and storing at the observatory.<br /><br />Additionally, if you have a Lego Digital Designer .lxf file of the wheel mechanism I would be eternally grateful!<br /><br />Thanks<br /><br />Dr Luke Tyas, University of DurhamAnonymoushttps://www.blogger.com/profile/11120411479042427743noreply@blogger.comtag:blogger.com,1999:blog-3824360734690778592.post-83899705341557787762018-01-30T09:57:45.152-08:002018-01-30T09:57:45.152-08:00Hey there - I know this is an older thread - I hav...Hey there - I know this is an older thread - I have been running into a lot of the same struggles (weight, balance, traction, etc.) that you have with my 4-wide layout. Do you have closer pictures of your vertically mounted motor setup that you would be willing to share?ritzcrackermanhttps://www.blogger.com/profile/13936534824452880075noreply@blogger.com
