      My work on wireless charging has been frustratingly slow.

      Reason is, after a series of tests, we received mostly negative news today about my medical condition. I will be re-focusing on other matters, so wireless charging, and a lot of other BPRC projects, are on the back burner for the immediate future.

      I regret disappointing some of you, but hope you understand. If I get some time, I'll post information on any progress I've made.

        Sorry to hear about your medical condition. I hope it turns to the better.

          My 1, 2 and 3 watt charging tracks are all wired. The transmitter board, power supply and controller for setting voltage and current are all delivered.

          Engine rewiring is about half complete, but receiver coil and protection board need to be mounted and wired into the system. I've added a 9V regulator and plan on adding some lighting so I know when the engine is on.

            Good to see your back at it again Dan. Glad to see you're doing better.

            Looking forward to your finished engine.

              For those following this conversation may not be following this on another forum. DanT posted with this subject line: "Dead Rail Makes Top 20 List". Apparently the January 2019 issue of Model Railroader Magazine wrote about the top 20 innovations. If you are interested in the whole conversation plus some controversy on R/C and battery powered engines you can read about it here. It starts with Dan's post. Third post down.

              Dan may just have forgotten to post it here.

                Thanks for helping to keep everyone updated. It's much appreciated.

                I didn't forget to post. My illness has reached Stage IV and visits to doctors and for treatment eat a lot of your spare time.

                And I have to admit I've not found the knack of posting photos on this forum. It seems a lot more cumbersome than Freerails or MRH mag.

                I have posted my progress, with photos, here:

                http://www.freerails.com/view_topic....49&forum_id=45

                It's pretty straightforward. The coil has to be installed on my GP35 engine, then I can begin some testing and gather up some data.

                At this point, I see so reason why it won't work since it worked under static conditions. The only reason would be excessive distance between coils.

                For that, there's another approach that will work better, but it's more expensive. I don't have the parts to try this anyway, so first things first.

                    • Hi Bernd

                      After a long period of being AWOL I have returned to RRLF, since I refuse to look at the other Forum. This topic seems to have died. Did you ever have any success? Decide that while it was possible, it wasn't practical? I replaced one of the fluorescent light starters with a New Improved Electronic one, and now I can't listen to a FM radio because of the buzz. Any chance that the same thing will happen with on the track charging?

                        Hey Herb,

                        Nice to see you post here again. Welcome back. Just got back on the forum this morning after a 10 day vacation at our second place up in the 1000 Islands.

                        That "other" forum has gone totally downhill. I don't go there unless I need some info on an item I know that's there.

                        Ya, this subject sort of has died. Dan T was/is a major force on this subject. I haven't seen or heard anything from him since his last post. I believe he was having some medical issues, not sure but I think they were serious. I wonder if he's still around. I have put this subject in moth balls because I'm concentrating on getting a layout built, plus still working on the house and other assorted non-model railroading projects.

                        As far as your thought on interference, I don't think it will bother FM radio. If it did a lot of people wouldn't be charging their iPhones using wireless.

                        I'm looking at RC with track power. My thought is using the Deltang receivers with on board rectifier and voltage regulators. This would allow me to run almost any micro gear motors from 12 volts on down to the 3 volt level using DC, AC or DCC on the track. Yes, alternating current or DCC. That's a bit into the future right now.

                        That's about it for now. Good to see your up and around.
