Trolleybus

I had left over motors from my one of power generating projects. Those motors had poor efficiency when I comes to power generation. They began to rust. This I decided to make a miniature toy trolleybus.

I used masking tape. You can use staples or super glue or glue gun.

I used two 6 V power source. The bus might move with only 3 V. Typical motors can ran on voltages from 3 V to 9 V. I suggest that you do not use a 9 V battery for this project. You will drain this battery (9 V) very quickly.

Supplies: sticky tape (clear or masking tape), low cost dual shaft motor - 2 (you might need spare), cardboard (20 cm (less than 1 foot in length) by 20 cm), insulated wires, hard insulated (or non insulated) metal wire (for terminals) - 30 cm, small wheels - 3 or 4, 1 mm metal wire (for miniature overhead power lines) - 1 metre, 6 V power source - 2 (eight AA/AAA/C or D batteries), 6 V battery harness.

Tools: scissors, hole puncher.

Optional supplies: solder, staples, blue tack or small stone (for front weight).

Optional tools: soldering iron, stapler.

I made the box from 15 cm by 15 cm piece of cardboard.

The length of my cardboard fixture is 9 cm. This is the minimum length. You can try 10 cm, 11 cm or 12 cm lengths.

I inserted the motor inside the box.

I attached wire terminals to insulated wires and sealed with masking tape.

Later I completed my toy trolleybus by attaching a weight at the front of the bus that you see in the picture on the first page because the bus was falling on its back.

You have to be careful not to short the positive and negative terminals. The batteries might explode. This is why I did not use two buttons or any switches. You can simply attach the wires to make the bus move.

I have drawn the circuit via online Easy Eda software (https://easyeda.com).

The video is showing collision testing.

I used one dual motor but you can make a this trolley bus with two dual shaft motors or two normal motors.
