1/87 Smart DIY micro RC car

I have converted the 1/87 scale BUSCH Smart Fortwo into the radio controlled model.
The steering is operated by 3.9mm diameter stepper motor and the drive by 4.1mm diameter DC motor.
Wireless communication is performed by two Bluetooth modules(RN4871U).
The RN4871U must be configured for communication before assembly.
The transmitter is built on the breadboard.
The microcontroller used is ATtiny3217 on the transmitter and ATtiny1616 on the receiver(the car side).
When the car decelerates from a running state, the brake lights light up automatically.
Headlights and turn signals are operated manually.
When the voltage of the Li-Po battery becomes 3.4V or less, the turn signals stay on instead of blinking.
The power supply for charging is DC 5V.
Even if Bluetooth communication is interrupted, it will be automatically reconnected.
The grid of the cutting mat in the video is 5cm square.
1/87スケールのBUSCH製 Smart Fortwoをラジコンに改造しました。
ステアリングは直径3.9mmのステッピングモーター、駆動は直径4.1mmのDCモーターで動作させています。
無線通信は2つのBluetoothモジュール(RN4871U)で行っています。
RN4871Uは組み立てる前に通信の設定をしておく必要があります。
送信機はブレッドボード上に組みました。
使用したマイコンは送信側がATtiny3217、受信側(車体側)がATtiny1616です。
走行している状態から減速すると自動でブレーキランプが点灯します。
ヘッドライトとウインカーはマニュアルで操作します。
車体に搭載したLi-Poバッテリーの電圧が3.4V以下になるとウインカーが点滅ではなく点灯したままになります。
充電用の電源はDC5Vです。
Bluetoothの通信が途切れても自動的に再接続されます。

I mean it's impressive enough to build a rc car at this scale but then you go ahead and put turn signals, headlights, brake lights, backup lights on it. Seriously impressive good job

[@evilash2388]

Indeed.

[@markm0000]

A little horn would have been hilarious.

[@jimmycline4778]

You should put air conditioning in it! 😃

[@ReflexWalaXD]

@@jimmycline4778 yaa also add a mini tv inside it

[@OnlyTwoShoes]

Needs windshield wipers with fluid jets.

[@jerzylisiewicz1633]

This is insane, headlights, blinkers, rear light and the most important: IT SOUND'S LIKE REAL SMART!

[@chovan22]

Even expensive RC cars doesn't have park lights, turn and hazard signals, brake light and reverse light! I am impressed, well done!

[@Martin_from_SC]

The lights absolutely complete this tiny little gem! Very impressive!👍

[@msmith2961]

Just need to add a horn and my mind will be truly blown! Ok, I admit, the lights already blew my mind.

[@Sonny_McMacsson]

Should've made it a BMW and then he wouldn't've had to bother with the turn signals.

[@claybrezenski7858]

And music...lol

[@megannason3649]

The control this guy has is amazing, he’s like a freaking brain surgeon!

[@jacobp8294]

Hey Pal, brain surgeons have a much greater amount of operating space.

[@AmericanMAN_2023]

Honestly

[@mehmetdedeoglu4577]

Please micro 4wd RC

[@1Himiko7Toga]

I mean what if he is tho

[@Sauv_27]

I think u went a lil bit too far

[@jeffrenman4146]

come on… You're simply amazing. The novelty of having such a thing just as a conversation piece is definitely worth the work you did… Most of us can't do that it's out of our reach. And some of us may not see any point. But it is truly amazing what you've created you would be like a proud father I'm sure

[@jonahbailey1119]

Nobody know how big of a flex this is. No custom PCB required. He really just deadbugged a no-lead attiny package. Amazing

[@dmitriyteslenko5836]

All project is amazing, but the lights... i have no words for it. You are great!!!

[@mitchib1440]

Not only did you add actual functionality to such a small model, you also added realistic lights. My god, that's impressive.

[@tom4od]

This is amazing! It needs to be driven around a miniature village with traffic lights.

[@NeedsMoreBirds]

Wow! It's so tiny, but you even set up all the lights like a real car.

[@NaughtyShepherd]

Absolutely incredible craftsmanship! I’ve worked with tiny electronics and smd leds, the amount of stuff you crammed into that little car without altering the shape took some serious forethought and planning.

[@Sykozona]

this has way more detail than a lot of expensive regular rc cars

[@poptart4247]

Building a care this size is already an impressive feat but Fitting headlights, brake lights, turning indicators, and other extreme details is a whole new level, I say you made darn we'll use of the space you had! And a good job too!

[@seekeroftheways]

I completely lost it when he began to install the turn lights

[@mikey52034]

Some people are creative and not talented. Others are talented and not creative. This man is both!

[@DangerAngelous]

Dude it could have just been lights, it could have just been able to drive, it could have just been a 1/87 car but god damn all three in a Smart. Massive respect

[@sergiorome48]

What I’m more impressed with is how you didn’t short everything with those exposed ass wires

[@marabushto]

Wires insulated with varnish

[@attilathenun]

Was gonna say the same thing.

[@jhwblender]

You have an amazingly steady hand. This would literally be impossible for me. The firmware development looked like it'd be fun! Seriously amazing job. Kudos

[@gqaot5714]

The amount of small gasps and smiles I made at every light changes is uncountable. This reminds me of the dream toy car I wished for my childhood

[@OGDooshbagg]

Nice engineering and that is some pro level soldering skills. This should be what the new hot wheels should be like.

[@TopKotXD_]

It is 10 times smaller than Hot Wheels, the scale is about 1:87.

[@turbokadett]

I sat here on a rainy Saturday afternoon with a coffee and hit play on this vid. As I watched I could feel my mind tingling as I tried to comprehend the skills required to put this together. I am in awe of what you achieved, fantastic!

[@idukry]

I watched this video also on a Saturday which has rainy weather which is today.

[@NemoThundersong]

This popped up in my recommended. I love it. Years ago there used to be RC cars like this from Radio shack called ZipZaps. I loved them, they were fully customizable. From the tires to the motor, they were popular but they changed the style of remote that came with them to the awful wheel and trigger remotes and sales for them dwindled and they died out. I wish they would come back especially with the tech we have now.

[@pamonha2312]

Imagine 50 of these rushing at you at night with the lights on.

[@reddeviluk]

I was already blown away... Then he started fitting the headlights and my head exploded.

[@npc4416]

ever since childhood i always used to dream about a very smol rc just car like this but i never found any, now seeming you make one has made my dream come true :')

[@theminecraftchido90]

sameeeeeee

[@observe_and_purport]

The reverse lights are such a nice touch! You make this look so easy. Thanks for sharing!

[@bondandng]

Bruh, this is UNREAL. Good Job

[@LeoNG628]

The masterpiece is all the control board wiring, he is brilliant

[@REN92106]

The most skilled surgeon could only wish to have such steady hands. This is crazy!!

[@davidnasa7480]

This was one the videos that ever put a smile on my face on KZbin. I enjoyed with joy and happiness as it was like my childhood dream came true. Great job and pretty sure this is boys thing. :)

[@Cian-_-]

i didn't even know this was possible... when you got the steering and motor running, i thought wow that was pretty cool, but then you kept adding feature after feature, honestly awesome

[@RajPatel-vy4fj]

Complete genius... my hat off to him!

[@user-lj7ki5ez1k]

Я просто не знаю как выразить свое восхищение...спасибо за эти минуты наслаждения увидеть непревзойденный талант и золотые руки !!!!❤❤❤

[@user-oz3vj3ry7u]

Левша 👍👍👍

[@malharapte5989]

My mind is blown, I can't even begin to imagine how much time, preparation and care this took.

[@PatPatych]

Making an RC car of this size is impressive enough but making the headlights work is just a flex.

[@Spaniate04]

this has more functions than any RC Car i ever owned xD

[@neriksen]

Clearly a Neuro surgeon in a previous life.

[@SybilGrace]

Competely next level. I dream of one day being able to build 1/64th scale. The lighting was worthy of applause.

[@AIexanderHartdegen]

Amazing. But you forgot the horn

[@Mandred85]

oof XD

[@Cloudy0w0]

You should do a video course on this and sell it, people would buy it for sure, I know my dad would love to have this for his model train set up.

[@stacy3]

You can get the normal unmodified version from eBay it’s kinder Smart Fortwo I collect those I have about 15

[@TomLandolt]

tbh, thats not a toy anymore. it's art. absolutely awesome job. love it.

[@TheSuperiorCat]

The amount of precision and detail is just insane :O

[@recepton.]

This is insane. You put that much controls in such a tiny thing.

[@ScottGrammer]

That is, I think, the most impressive DIY work I've ever seen on KZbin. And beautiful soldering, by the way. Subscribed!

[@unebonnevie]

The way he soldered the microcontroller ATTINY in QFN format on a perf board (at 8:50) is just insane! I am an engineer and can do all the electronics in this vid, but the soldering level is just amazing! Very steady hands!

[@ToninFightsEntropy]

I got so many of these little buggers in kinder eggs when the car was released. I'm familiar with every inch of this model and thoroughly enjoying watching this legendary upgrade!!!

[@Raul_Gajadhar]

This has to be the most amazing thing I've seen in quite a while. Your engineering skills are amazing. Great job on this diy build.

[@craigdavidson2278]

This was my dream as a kid (50 years ago) having working headlights and indicators on my matchbox/corgi/leseny/dinky cars..... a MkII escort with lights....AMAZING.....Ford Zodiac with break lights...WOW and ausin 1300 with hazard lights....OBLIGATORY. thanks for the vid

[@Chris-he3lb]

Thank you for listing all of the parts utilized, it is helpful for an amateur electrician.

[@ahumblepoet]

That is a modern-day Faberge egg. Incredible talent. I can’t imagine what one would cost.

[@wonseok_song]

Quite amazing you managed to put two motors in that small space.

[@comiccat4650]

He even made it pretty close to the actual size of the car!

[@KiwiMaker]

Dam thats impressive! I laughed when you put the 3rd brake light in, so much detail!

[@mbogobot]

I didn't move or breathe I was afraid to stop you from working miracles Thank you! This is very skillful and beautiful It is necessary to remove the red-green lamp for the battery, in real smart he's not there. connected charging = brake lights came on when the battery charge is 100%, the turn signals blink

[@Chisito23]

You've outdone yourself with the lights lol Great work!

[@djisydneyaustralia]

The functional lights, haha the icing on the cake! Well done

[@xadev9848]

THAT, IS, INSANE... Incredible work!! and unreal precission O.o

[@user-bh9cl3be1c]

precision ?

[@TomLandolt]

the electrical here is 100% better than 99% of light kits available and or implementations by ANY RC brand. spot on.

[@alexandertsigaridas5411]

My childhood dream just turned into reality!

[@hageneber3381]

That's soo cool. I probably wouldn't even be able to plug the charger in.

[@lovienyoutube420]

wow...cant get my head around how good is this built...it just keeps getting better thanks for sharing

[@joshziv9182]

I was half expecting there to be powered windows as well

[@davidyoung518]

Same thing crossed my mind!

[@Alniemi]

Incredible! even the lights work, youre a craftsman and a genius!!

I would live to see a tiny Mazda Mx-5!!

[@IcicleFurry]

This is next level impressive, I have never seen something this feature packed and so well-built!

[@byte2600]

Wow, I am blown away and that is someone that does projects like this.

[@robertsollory7475]

Fully operational lights just like the real thing...... nothing short of incredible!

[@rafiqkatana]

That's the most impressive thing I've seen in a lot of years. And as if it wasn't cool enough. ..then it has low and high beam headlights. No doubt many others have said the same, but I wish I could buy one. It's a true piece of Art. I'd have it displayed on my mantle as the major showpiece. Although I don't think people like me are supposed to own expensive things like that in our lives. Still it's a nice dream. Awesome craftsmanship. Wow! I forgot to add that I love how you made your own remote for it. It just makes sense to have one you've made to go with it. I'm really jealous.

[@BlimpMcGee]

Woah that's at least half the size of the real thing

[@Matyas_Ceo_Of_Matyas]

and 87 times smaller at most.

[@rashadbudagov4815]

I mean and I'm saying that I was really busy but literally for a moment came across this video and I blacked out absolutely 100% . I enjoyed every second of this video and I want to say thank you so much it's brilliant!

[@qanatuka]

The amount of control and mastery over your fine motor movements is unnatural, wow!

[@JustWasted3HoursHere]

Back up and brake lights that activate automatically too? Damn, this is impressive! A steady hand and extreme patience is your forte. Good job! [edit: _AND_ low beams and highbeams? WOW!]

[@peymanzakhire7487]

Work Of Art. loved the last scene where compared on laptop, realizing again how small is the scale 😍 loved it brilliant.

[@icraftcrafts8685]

i did not expect it to get lights too. amazing work!

[@ashwinrawat9622]

Now you must make a mini crane to lift my jaws from the floor.

[@jarnorajala]

You could probably fit in an ExpressLRS receiver instead of Bluetooth, so you could use something like Radiomaster MT12 to control it like a proper RC car.
