1/150 scale DIY Micro RC Truck & Trailer

I modified TOMYTEC 1/150 scale “The Trailer Collection“ into a radio control car. The motors are LA4-466FB for both steering and running. Wireless communication is done with two RN4871U (Bluetooth module). RN4871U must be set up for communication before assembly. Wireless communication from trailer head to trailer is infrared remote control. The transmitter is built on the breadboard. The microcontroller used is ATmega88V for the transmitter, ATtiny3217 for the trailer head, and ATtiny412 for the trailer. The power supply for charging the trailer head is DC 5V. I omitted the trailer charging circuit. The grid of the cutting mat in the video is 5cm square. TOMYTECのトレーラーコレクションをラジコンに改造しました。 モーターはステアリングも走&
