Well an update that will have to do for this weekend and last weekend.
Been trying to get the HandCab-DC throttle to a place where I can consider it finished (mostly). Not much progress that can be shown visually. Been working on the final wiring configuration and rewriting a lot of the code for the Arduino Nano. The actual motor controller that controls the motors speed is pretty darn simple and basically what I covered ( HERE ) with a simple cheap ($4.00) DC throttle that one can put together in short order.
The HandCab-DC puts that $4 motor controller in a throttle case that makes you control the loco more like ....
... how an engineer would control the speed and direction in a GP-7 cab. Makes running the loco a lot more interesting vs. a simple knob control.
I've got probably over 25 hours in the past week and a half creating sound files for the throttle, changing the wiring and rewriting most of the code that controls the sound functions on the throttle.
You can see, mostly hear what/how it will work in ....
... the video above.
Hopefully the next update might be the throttle with all of the above in the throttle case and actually controlling a train.
