1/150 Micro RC "Dual Mode Vehicle" DMV-931
HTML-код
- Опубликовано: 3 июл 2024
- I modified TOMYTEC 1/150 scale Dual Mode Vehicle (DMV-931).
DMV is a vehicle that can run on both roads and rails.
Normally it runs on roads as a bus, but by protruding railroad wheels it can run on rails.
The microcontrollers for both the transmitter and the receiver are ATtiny3217, and the motor drivers are DRV8835 (two units) and DRV8212.
The driving motor is a diameter 4mm DC motor. The steering and mode change motor are 3.9mm stepper motors.
The motors were purchased from online shops, and the gears were taken from broken digital cameras that were disassembled.
Communication is carried out via serial communication between two Bluetooth modules (RN-4871U).
The battery is a Li-Po (55mAh).
The thin copper wire is magnet wire with a diameter of approximately 0.08mm.
[Dimensions (Bus mode)]
Length 53.5mm
Width 13.8mm
Height 18.0mm
Wheelbase 26.5mm
Outer tire diameter 5.0mm
TOMYTECの1/150スケールのDMV-931(Dual Mode Vehicle)を改造しました。
DMVは道路と線路の両方を走行できる車両で、通常はバスとして道路を走行しますが、鉄道用の車輪を出すと線路上を走行することができます。
マイコンは送信機・受信機ともにそれぞれATtiny3217、モータードライバはDRV8835(2個)とDRV8212を使用しました。
モーターは走行用が直径4mmのDCモーター、ステアリングとモードチェンジ用は直径3.9mmのステッピングモーターです。
モーターはオンラインショップで購入し、ギアは壊れたデジカメを分解して取り出したものを使いました。
通信は2個のBluetoothモジュール(RN-4871U)間でシリアル通信を行っています。
バッテリーはLi-Po(55mAh)です。
細い銅線は直径約0.08mmのポリウレタン線です。

i always forget for you it isn't enough to just make it remote controlled, it also need more lights then the average BMW driver, outstanding work mate
I always feel so defeated every time see him solders QNF24 and smaller component packages on test board. This guy has hands of a neuro sugeon!
I wish my hands were that steady!
Fr frr
Neuro surgery is how this guy relaxes between making these models lol.
He gets great solder wetting on those tiny gauge wires.
The skill to just solder the tiny copper wires and the microcontrollers and stuff are amazing!
Keep up the good work man!
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!
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!
Absolutely beyond impressive, you have mastered micro RC! Here I am thinking my 87s were tiny and too hard. Inspiring!
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???
Agreed -ho scale modeler)
I am once-again absolutely flattened by my astonishment at how you make such a feat of engineering look so easy every time!
And even then- you take it one step further and completely lay-out the items used in a clear and concise manner.
Cheers again for such a wonderful showing of talent and good old-fashioned hard-work!
I have no words, just admiration
I was stunned by the fact that he got the dual mode to work, the working lights, turn signals, backup and brake lights are making my manhood shrivel.
A treasure trove of intelligence and skill.
Absolutely mindblowing! 😯
Wow that's pretty amazing considering the size and all. I think the owner needs to sell these as kits.
This might be the most impressive model I have ever seen!
Crazy bus in real life
デュアルモードまで再現しているのが凄すぎる！！
I loved the scale shot at the end. I'd forgotten just how small it is until then.☺
私もdmvの模型は持っているがtrain modeの再現が限界だったのでバスモードも再現している上にモードチェンジにも対応している技術力に感動しました。もしこれが10万円で売られてたとしても即決していただろう。
栄一10人くらいでは買えないだろう。昨今の半導体不足(と一匠特許権？)を加味しても20人クラス
Köstlich, diese arbeit ist nur was für Genies. Bravo !
Incredible! I love this one so much. Even the sound of the motor is great. If I'm ever a tourist in Japan I want to ride a hybrid bus.
凄い、素晴らしいの他に、言葉が見つかりません。
this is so awesome! I admire your work!
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.
This is one of my favorite hobbies of others that I enjoy watching. Thanks for sharing!
beautiful work
Hey look, he's back!
Amazing work! And full RC control, too! In America vehicles like this are called, "Hi-Rail" vehicles. Most are small trucks used for track inspection or larger trucks needed for track maintenance.
Сложность проектов повышается! Класс!
Great job!
Bro, your videos really inspire me to study more so that even i can make things like this in the future!
These videos inspire me to study more so I can create things like this in the past
Great job👍
Very impressive!!
"Driver's license passed for street and rail" :-))) ... "👌👍" ... Regards😉, crazy Olli
WOW, daß ist der Hammer in 1/150! 👍🏻👍🏻👍🏻
Sowas hätte ich gerne für die Spur Z im Maßstab 1/220.
Great Work!
that is incredible.
wow.
Un vero Maestro! 🎉
Besides steady hand and infinite patience one must know a lot about where to get these parts in the first place.
Hobby stores and rc stores.
Ты гений! Восхищаюсь твоей работой!
First class job!
This is genius ❤
awesome!
thanks for sharing
你们辛勤工作的成果给我留下了深刻的印象，它需要很长的时间和精密的相机，更不用说组装它所需的材料了。
感谢您翻译此聊天内容，朋友 😊😊❤❤
How’d you know lol?
Very impressive! I am trying to design a BLE receiver for 1/87 models, and I'm not even sure it can be made smaller than your 3D electronics
Just fantastic 👏👏👏
What one would pay for something like this! Amazing work
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.
Would you publish onr day a full step by step tutorial including programming electronic chapter ?
Amazing !
I have been questioning me this, since i was little!
Very impressive.
Awesome!
8:30 I thought you were gonna jump over some scale motorcycles ;)
Great skills sir
Awesome👍
Impressive.👍
Incredible.
あなたは天才です。 あなたの仕事は素晴らしいです。
Gimmick System Perfect Amazing!!!!
So cool !
Это просто обалденно👍
So cool 👍🏻 i wan't learning to your talanted ❤
hypnotic, almost.
Artistic
Astonishing
And I think, i am crazy with my N cars.. But this is absolut high end.. Wow... Respekt
AMAZINGNES!!!
Sooo good!
Bravo ~ excellent work. KR AndyT(UK)
今回も素晴らしい出来ですね！
毎度ながら驚かされます。
オフロードカーなんて作ってみてはいかがでしょうか？
スズキ ジムニーや三菱 パジェロなど
凄すぎます。
Sehr gut!
Обалдеть 😯, очень трудоёмкая работа, золотые руки.👍
Жду модельку легендарной AE86 Trueno! 😄
Привет из России.
----
素晴らしい😯、非常に労働集約的な仕事、黄金の手。👍
伝説のAE86トレノのモデルを待っています！ 😄
ロシアからこんにちは。
Impressive
Вы молодец!
I think I saw this on Tom Scott's video
Sooooooooooo cool!
芸術的です！
A full size one of these buses was featured on one of Tom Scott’s videos.
:) again lol incrédible is true realistic bus :D tks for your works-rock micro
I was thinking ' that's impressive turning radius' then he proceeds to parallel park!
This is insane level 😮
Where do you shop for whires leads and components to build this...?
Same as everyone, china. Only difference is that he's japanese so he's very close
Wow😁
So satisfying 🤌 both assembly and demonstration are masterfully framed and timed. Love it.
How long did it take you to shoot and cut the video?
Do you do preproduction test assembly?
Wow 😮
ФАНТАСТИКА!!!❤❤❤👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻
Try doing bottom plate as double sided PCB. Down part for ICs and top for motors.
i can't look away
진짜 쩐다
Oooh! A hi-railer!
👍🏻👏🏻👏🏻👏🏻👏🏻
Wow
I want to do this in 1/87 scale
Can you please try 1/64 scale next time maybe Lamborghini huracan I think
incredible as always! is the noise coming from the servo? can this be elimenated with some filtering in the servo loop?
Nope, the sound comes from gears scrambling together do to imprecise assembly / cheap gears.
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.
Where can i buy these small gears and dc motors, that you used?
Belo trabalho. Gostaria de saber onde ele encontrar os materiais como buchas, eixos, essa placa de alumínio, etc. Parabéns pelo conteúdo
😃😃😃
HEY THERE, Why did you took off the "smart for two" red car tutorial, it was an amazing one ?????
In order to increase the number of views for this video, I have made my other videos private. Someday, I will publish them again.
@@diorama111 okay good luck!
jesus christ !! this is insane
I see this 1/2 i mean numbers like this in lots of diorama videos, what does it mean actually
It's the scale of the model - this one is 1/150 the size of the real thing
