  • Turn on the Laptop With the Lid Closed

    As promised earlier: here is the remote version driven by Blynk (see blynk.cc)... Still have to test it with the remote laptop though! But it works to the point of gently inflating the balloon, so looks promising!

  • Turn on the Laptop With the Lid Closed

    I've been looking for a way to give a remote "wake on lan" style functionality to an old laptop that doesn't have it. By using a networked Arduino style board and a cheap air pump (of the kind used for aerating aquaria) it should be possible to get this functionality for about $10. The pump costs about $5, it should be possible to control it remotely with e.g. a WeMos D1 mini ($3) and the Blynk app (free) and a transistor and step-up power supply (<$1). I'm going to try connecting your hand pump too via a three way connector so that both the manual and the automatic options are available.Thanks for the inspiration - I have ordered everything on Aliexpress and I will come back to you in a couple of months with news of whether it works..!

    Maybe you can make this even simpler - can't you just tell the laptop to stay on when the lid is shut (I'm pretty sure you can in Windows, using Power options in the control panel or similar). Then all you need is the balloon and pump?! Has anyone tried this I wonder?
