It’s rainy outside… that means no sun to power all the solar toys, stuff, things, chargers, whatever you have on solar power. So what a great opportunity to start building a solar powered toy! Do you know how to make a toy car?
Good to begin with, because a solar powered toy car is well… more easy to make then let’s say a solar powered helicopter. You have to begin somewhere, eh? OK, so what do you need?
Let’s look at the ingredients.
How to make a toy car
- small solar panel (to be found on Amazon or eBay) 1 to 2 volt is sufficient, also to be found in old solar garden lights
- DC motor 1, 2 or 3 volts, around 145mA (hobby motors on: Amazon or eBay)
- wheels: 4 caps from plastic bottle (the bigger the better)
- car chassis: empty water bottle or milk container
- car axles: two skewers (you know, for kebabs!) and two straws
- utility knife and/or scissors
You can also use an old CD-player for bits and parts and use a DC motor from an old mobile phone (which causes the phone to vibrate).
Now let’s take a look at this video for instructions:
As you can see, the basic is pretty simple! Just replace the battery with the solar panel. I think if you make holes in the sides you don’t even have to glue the straws to the bottom of the bottle.
Here are also some cheap solar kits with all parts included, like a boat, etc. Take a look here: educational solar kits.
This must definitely be the smallest solar powered toy car I’ve ever seen….. The electric motor is from an old mobile phone!
Check out this Czech website (translated) with lots of pictures of homemade toy cars. This guy even made a car which runs on juice and vinegar!
DIY solar toys
This toy car runs on cold water (in a small tank on the left) and the heat of a candle. Due to temperature difference it creates a thermoelectric effect (Peltier effect) to run the electric motor.
