Has anyone heard if Lionel plans to offer the electronics as separate sale? Just had the thought that they might not be bad for those of us with old DC engines.
haven't heard it, and sort of doubt it will happen. I agree with Landsteiner that the radio in use in LC/+ is superior to the systems used by the two big systems in 3 rail. That said, I'm unsure what the marketability is for the boards that are in production as they depend on tow things many older engines may not have, and may not be able to be retrofitted with. for LC functionality you need motors that don't draw a ton of current, and for LC+ the motors need an optical encoder to detect motor speed. Now this isn't to say that the same functionality couldn't be easily duplicated, just that the current design would probably be more hassle than it is worth to turn into an upgrade product. Add to that that I expect Big L figures they already have remote upgrades covered with ERR products, which, as far as I can tell, are some good products.
Now, MRC offers a simple remote system based on the same underlying tech as LC/+ that looks fair from what I've seen. Also there is the BlueRail option using bluetooth to run trains from a smart device which also looks like it's shaping up pretty well. Both of these, however, are only good for very low current motors, looking to be geared to HO at the moment. I expect one could pretty easily kludge together a high current driver for either of these... but if you're going that far you could probably also build your own wireless link and eliminate the middle man.
It is worth noting that BlueTooth, and Wifi are both the same underlying radio tech as LC/+, just with much better software telling the radios what to do.
Getting really far off topic, I'm kicking around building boards that would be a drop in replacement for a TMCC R2LC that would use the 2.4GHz radios of the sort used in LC/+, eliminating the signal issues that TMCC/Legacy faces. One could also build single engine remotes to run these engines if they wanted to, though I'm unsure if that is something people want or not. With this sort of R2LC replacement board one could use ERR boards as well to convert anything to an LC+ style control. This project is on the back burner right now, But when I have something to show, it will be on the forum.
