Sir TophamHatt Posted December 21, 2018 Share Posted December 21, 2018 Not really sure what I need here. Basically, a loco travelling between two points, slows, stops, reverses and does the same at the other end. Am I right in thinking I need two BM1 units from Lenz and a suitable chip? Finding them hard to find online (although I haven't looked too intently). Or is there a guide for home build versions? Link to post Share on other sites More sharing options...
RMweb Premium Ray H Posted December 21, 2018 RMweb Premium Share Posted December 21, 2018 I posted a similar request a few months back. I've made several of the home made BM1s and we use them on our club O gauge layout and I have a few on my 4mm layout at home. Link to post Share on other sites More sharing options...
Nigelcliffe Posted December 21, 2018 Share Posted December 21, 2018 Yes, follow thread Ray linked to. For automatic shuttling, it needs a Lenz decoder (most other makes which support Asymmetric brake stops don't do the shuttle reversing), plus the brake modules. DIY brake modules are half a dozen diodes, so cost under 50p, I would have written them up years ago on my blog. Link to post Share on other sites More sharing options...
