code for new hatch

/*
  You are free to modify the code as much as you want and share it with other people if you want. Try to add any improvements and bugs to the original git hub repository so that i can take a look as well, of course this is not a requirement.
  do not delete this comment section, as this will help the next reader link to the original post and original content. This is necessary to avoid any confusion later on. Happy tinkering!
