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.
@mhall119 I just learned about this the other day:

@gemlog Wow, we're going to have entire computers the size of an SDCard soon
@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).
@gemlog @mhall119 well, I don't know why I called to this thread but exactly I have Lichee Pi nano. This board (LPi nano) does not have any network connection but LCD/audio capability.
I think this board is for old ARM (not Cortex but ARM9 core) fans. Here is the processor F1C100s datasheet, please read this and check whether this SoC fits your project. https://linux-sunxi.org/images/b/ba/F1C100s_Datasheet_V1.0.pdf
@gemlog @gemlog @mhall119 my project... Simply I want to play wih old ARM9 CPU core, not modern Cortex. Now I am trying to port KOZOS, a tiny embedded OS for education. (web page is written in Japanese) http://kozos.jp/
@uaa @gemlog @mhall119
I am too old to learn 3-4 different writing systems! :-)
Here is a computer translation of the site

@mhall119 NB it's 5am in Tokyo and he usually answers late at night his time.
@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
