- 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 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.
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
The skill to just solder the tiny copper wires and the microcontrollers and stuff are amazing!
Keep up the good work man!
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)
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!
Wow that's pretty amazing considering the size and all. I think the owner needs to sell these as kits.
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.
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!
Absolutely mindblowing! 😯
A treasure trove of intelligence and skill.
I loved the scale shot at the end. I'd forgotten just how small it is until then.☺
This might be the most impressive model I have ever seen!
デュアルモードまで再現しているのが凄すぎる！！
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
beautiful work
Köstlich, diese arbeit ist nur was für Genies. Bravo !
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!
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.
This is one of my favorite hobbies of others that I enjoy watching. Thanks for sharing!
Great job👍
"Driver's license passed for street and rail" :-))) ... "👌👍" ... Regards😉, crazy Olli
Great job!
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.
Crazy bus in real life
Hey look, he's back!
Would you publish onr day a full step by step tutorial including programming electronic chapter ?
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 Work!
Very impressive!!
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
8:30 I thought you were gonna jump over some scale motorcycles ;)
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
First class job!
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.
awesome!
thanks for sharing
that is incredible.
wow.
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.
WOW, daß ist der Hammer in 1/150! 👍🏻👍🏻👍🏻
Sowas hätte ich gerne für die Spur Z im Maßstab 1/220.
Ты гений! Восхищаюсь твоей работой!
Amazing !
This is genius ❤
Un vero Maestro! 🎉
Just fantastic 👏👏👏
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?
Awesome!
Great skills sir
Awesome👍
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
I think I saw this on Tom Scott's video
Very impressive.
Impressive.👍
So cool 👍🏻 i wan't learning to your talanted ❤
Artistic
AMAZINGNES!!!
So cool !
I have been questioning me this, since i was little!
Incredible.
Sooo good!
あなたは天才です。 あなたの仕事は素晴らしいです。
Bravo ~ excellent work. KR AndyT(UK)
凄すぎます。
And I think, i am crazy with my N cars.. But this is absolut high end.. Wow... Respekt
Gimmick System Perfect Amazing!!!!
Это просто обалденно👍
Astonishing
:) again lol incrédible is true realistic bus :D tks for your works-rock micro
hypnotic, almost.
Sehr gut!
A full size one of these buses was featured on one of Tom Scott’s videos.
Impressive
Sooooooooooo cool!
芸術的です！
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
Вы молодец!
I was thinking ' that's impressive turning radius' then he proceeds to parallel park!
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?
Where can i buy these small gears and dc motors, that you used?
Wow😁
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。
Wow 😮
ФАНТАСТИКА!!!❤❤❤👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻
Try doing bottom plate as double sided PCB. Down part for ICs and top for motors.
I want to do this in 1/87 scale
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.
진짜 쩐다
Maybe this scale is the smallest RC scale we can made, 1:87 for me is small, but this one is more smaller!
Can you please try 1/64 scale next time maybe Lamborghini huracan I think
Belo trabalho. Gostaria de saber onde ele encontrar os materiais como buchas, eixos, essa placa de alumínio, etc. Parabéns pelo conteúdo
i can't look away
👍🏻👏🏻👏🏻👏🏻👏🏻
Wow
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
Oooh! A hi-railer!
I don't know how you do it so that your hands are not shaking xD are you a human? :D
😃😃😃
