I've started doing some hardware hacking as part of my new job, I'm amazed at what is available these days. This NodeMCU costs about $5, has built in WiFi, is programmable through the Arduino IDE and can be powered by a small solar panel. I'm blown away.

@gemlog Wow, we're going to have entire computers the size of an SDCard soon

@mhall119 If you don't need a display, that pretty much *is* an entire computer. couldn't you ssh in on the usb connector? Am I wrong maybe?

@gemlog You can probably use screen to connect via serial console on USB (I do that with my NodeMCU), but it doesn't look to have on-board WiFi or Ethernet capability

@mhall119 yeah, I did notice that, but you could still compute with it.
Yes, it's not very useful without other network connectivity.
However, it depends what you are doing. I once created a fairly complicated set of network scripts using only my pc and a sharp zaurus (because that's all I had).
