I have been working with the esp8266 for the last 2 weeks and I love it.

I have setup a arduino (1.6.5) sketch using the staging (unstable) version of esp8266. I have added Over The Air update so I can update the sketch using wifi. Also debug information is send using wifi by simply connecting telnet. Check the github repository for the sketch.

I have seen a lot more interesting new software features of the esp8266 which I will explore later.

Also looked at why the peristaltic pump leaks. The silicon tube got damaged. I think the gears rolling over the silicon tube is not the best idea. Also where the tube enters the pump there is a sharp corner. Well you get what you pay for ;)
