automine.js

function automine (n) {
   var n = n || 5;
   setInterval(function () {
		if (!eth.mining && (txpool.status.pending || txpool.status.queued)) {
	   		console.log("miner start");
	   		miner.start();
      	}
		else if (eth.mining) {
			console.log('miner stop');
			miner.stop();
		}
   },  n*1000 );
}
