A quick lego hack to save a few dollars

I always like the idea of taking something and hacking it into another and as you may know I am a Lego geek. After playing with lego gears and motors from the WeDo set I cam across the video below and it looked like a pretty fun way to try and create something new for a virtually no price.

Small gearTake a 50cent motor from your electronics resources, a peg to star technic connector, a small gear and a hot glue gun and a AA power source. Glue the peg to the drive shaft of the motor and make sure that it sets straight. Wait five minutes and you have a mIMG_0218otor. Now the motor is very simple and a bit too powerful, but I am sure that with a bit of gearing down you can make it work quite nicely.

It is as good as a store bought motor? No, but it is always a lot more fun and rewarding when you make it yourself.

Watch the video below and give it a go or show your class and let them have a go 🙂
