Sounds like a train on the tracks, lol. Cool concept and build! Always impressed with how you cram all that in there. The DIY boards always surprise me. Great job!
I think it's the pwm control of the dc traction motor; it's a pity, probably there are better (but more expensive) controllers that use higher pwm frequency; or probably... there's no solution with that tiny motors 😊
@@mdani76 oh, i see what you mean. maybe if one puts a capacitor across the motor terminals, that would probably filter some of that high switching frequency
@@romyaz1713 maybe... I see the author's video with a lot of expertise so probably there's no solution. those tiny motors have no inertial mass so they respond sketchy to pwm impulse and make that awful noise.
As someone who works with "N" scale models as a hobby. The stuff this guy does is extremely difficult. And then put the applied engineering on top of the already difficult task since this requires both programming and a degree of familiarity with the circuits used that few hobbyists got. I would sometimes wish that a manufacturer picked up on some of the ideas this guy has! Tomytec, Kato, Faller are you listening out there???
Hello thank you＋👍 very much, but I don’t have an ISP adapter. I use an Arduino board to externally convert it to an ISP. In Clock, I choose 9.6MHZ to upload, and it is also successful. I have no problem testing MP3 and buttons
WOW, does not even begin to describe my amazement at your skill and patience, New subscriber here, and look forward to binge watching the rest of your videos. Just WOW WOW WOW.
Oh man, let me see this on a layout pleeeeease. I saw a news piece of the full size one and it's introduction to service. The aesthetic was immaculate. This is amazing.....maybe black out the windows tho.
What an amazing approach to challenging yourself. You decided instead of making it smaller, which I've seen you've built smaller vehicles; you chose to make it more complex. Simply amazing! Thank you for sharing this with us!
