      Pete's Rail Truck

       

       

       

       

      Pete Thornton sold me this fine rail truck a couple of weeks ago and I've been having a lot of fun with it- I thought some folks might want to see my various hacks.  I tossed the back end goose body and made a new shell sort of thing from sheet styrene and added some 3D printed parts. (those white blocks are unpainted suitcases from thingiverse). I also shortened up the drive train and redid the truck mount and it seems to work ok so far, it's crawling across my work bench just fine.  I've still got a ways to go but it's getting there. The sound card powers up and has a pretty neat rumble.  Still need led lights, hinges on the doors, some other odds and ends etc.   Good fun for fall and rainy cold weather.

      So you managed to use the Sierra card?  Looks great!

       

      P.S. I thought it was a winter project?  It's not even November yet.

      Here is a quick video I put up on Youtube.  It still needs some tweaking but I got it to run with the Protothrottle.  This is driving a Pololu 18v7 ESC.  I added some code to control a port pin with Function 0 to turn the lights on and off.  Also found an old HO tsunami decoder with an ooh-gahh horn so I put that in there as I had to take out the Sierra card, it started acting up.   I think it's a bit slow with 11.1v lipo, perhaps I need a 14.8.  Back bolster is also not quite right, it leans on uneven track but I'll fix that up next weekend.  All-in all, a very fun project, thanks Pete.

      Is there a blinking light inside?

      I was not aware the angle between the rear "driveshaft" and the motor was so severe.

       

      Looking good though!

      Yeah, the underside rear was heavily modified, someone ground down the metal with a dremel or something.   I made a new bolster and put it where I though it looked the best but it did make for a rather severe angle.  I thought about a new drive, perhaps a flexible shaft, but just cutting down what was there and putting a small spring on it to keep the gears engaged seemed to work ok.  The blinking light is the Pololu motor controller, when it gets valid R/C it blinks.  I was thinking the 2.2 amp tsunami decoder would probably be enough but I had already wired up the leds to the relay in anticipation of using the Sierra card.  I found the oogah sound by accident (a bug in my CV code actually), it's not listed in the sounds but its kinda cool so I went with that.  I do wish I had a better engine sound but that will have to do for now.  It is a bit anemic on the 11.1v, I want to tow at least one car with it so I'll probably swap out the battery at some point.  I find I really enjoy buying used thingies and goofing with them, this was way fun.
