This is typically a power issue. The ESP-board is and the USB-output of the computer does not provide enough power. \nThere are two fixes: adding a big capacitor (e.g. electrolytic capacitor [[Elko]] 2000 uF) or adding an external power source (e.g. [[USB-Power]]). The external power source is the better solution.\n\nHave a look at the video for details.\n\n== Adding a Capacitor ==\n\n[[File:PowerElko.JPG|400px]]\n\n== Connecting an external Power Source ==  \n\n[[File:PowerUSB.JPG|400px]]\n[[File:PowerUSB-module.JPG|270px]]\n\n[[File:PowerUSB-setup.JPG|400px]]"
