For your evaluation

[Tom Dempsey]

Every Power Pack I have seems to be a pulsed unit (most are MRC or starter set packs) and they are "messing" with the board I am currently trying to install in a locomotive. What I want is up to 6 amps of straight DC, no ripple, no pulse, a straight line on an oscilloscope at 12 volts. Your evaluation would be gratefully accepted, brutality is allowed/encouraged (if necessary). Thanks, as always, Tom Dempsey

Another approach is to fix the onboard electronics so that they'll work with standard power supplies. What is this board you're using?

BlueRail Trains, eventually it will theoretically lead to onboard battery power, but I like to do my learning in bite sized steps when possible so I'm starting with a more standard install. It ultimately should make more sense to just jump all the way to onboard battery power for me personally, however, I also have to look at the store situation. Not everyone is comfortable with battery power.

I've got 3 engines with the BlueRail board inside, A Williams E7, Weaver RS3, and Bachmann G-scale 4-6-0.

I added a bluetooth sound board to the E7 so now the sounds come out of the engine vice out of my Ipad. It's not the finest sound available but it does give me diesel rumble, horn, and bell. I even have a bluetooth gamepad so I can control the engine without having to hold the Ipad. Hopefully they'll offer a board with 3-6amp capacity soon, the 2amp just doesn't have what it takes, although I played around with the adjustments in the software and got the engines to run without tripping the polyfuse.

Tom, Being nobody really answered your query i thought I'd do some digging...found this site:

Thanks Bob, Dan (RDSRR) offered me a better alternative during a phone call and once the parts arrive, and I get back from OSW, I'm going to follow it and see how things work out. I will post the end result. And to all of you I do appreciate all the input. As always, Tom Dempsey (stop by and throw me shade in Santa Clara if you feel the need)

I built a transistor throttle years ago for HO. Still have it but can't find the schematic of it anymore and don't recall how it connected to the P.S. It worked well though, has the transistor on the outside of the metal case (to help in cooling) and used 4-wire telephone connectors/cable.

I also have an old Aristocraft Train Engineer:

that I have used on both HO and G scale trains. I think the base is good for 10amps. It should work fine on O scale as well. Both systems needed a transformer, I think I used a 12v wall wart last time I hooked it up.

That's sorta what Dan and I cooked up, time will tell. Thanks, Tom Dempsey
