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。
動画の中のカッティングマットのマス目は5cm四方です。

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.

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.
