I'm kicking around ideas for a DIY "steam look" throttle. There is an ongoing discussion thread about a steam proto throttle much like the diesel version elsewhere on the forum but it's probably a bit more involved and likely, like it's diesel cousin, beyond my means. My idea begins with Geoff Bunza's excellent SMA 30 WiFi throttle and then making it look and maybe somewhat act like a steam loco throttle. All I have are ideas right now and nothing is set except DIY and markedly cheaper for me to build than what's being discussed for manufacture.

My tiny around the walls 8' by 8' ( yes, the room is only 8 by 8 ) has 20 Atlas Mark IV #4 switches. I think it's time for the addition of ground throws. I looked at Walthers website, confusion reigns.

Suggestions?

Group,

I have a question about the two versions of the free switch list on this group.

I have been following this and working with the Switch List a long time. I use Excel from Office 365, so the spreadsheet is in that form.

I retired from my job July 2017 and while working I had a friend at that job that was a spreadsheet guru (my word).

An idea started forming while I was reading the thread on the steam locomotive proto throttle.  (DISCLAIMER: I don't much about electronics, I spent my working life in the US Army (Infantry) and then in law enforcement after I retired from the Army so what I am proposing may not be possible, but I think it could be made to work).
