Happy New Year!
In another thread, I asked about running HO gauge DC engines using MTH's TIU along with the wifi/app as controller. A couple of ideas on how to use the TIU's AC output variable channel to do this. The one that interested me was to use an old e-unit from an O gauge engine.
I was wanting to know more technical details to help with the set-up. I have never seen an e-unit, but I assume it is a small piece inside most AC driven O gauge engines.
Thanks for any more help with this work around.
