Hello everyone, this time I made a caravan out of 2mm cardboard. The main body of the car is illuminated by 5V LED lights, and the remaining lights are 3V LED beads. When powered by USB, for beginners, it is worth noting that each 3V lamp bead needs a 100 ohm resistor in series. I also used 3D printing waste, which is a very good material for making stones! I used a fly swatter to DIY a grass-growing machine. The effect is very good. If you want to make it with very little money but don’t know how to do it, I will send you a video tutorial. It is very simple and fast! Hope you like it! Thank you for watching!
