finally, the project wasn’t a success but with more components, time and knowledge, it could be feasible. The most important step to keep is, make a solenoid with copper, put a magnet in the middle and create a movement. Create a link between the solenoid and rectifier bridge with Ac and same with DC between rectifier bridge and batterie.We would like to say thank you to the CRI to give us a chance to make a project in English.
